Technical Field

The technology disclosed by the present specification relates to a female terminal.

Background

as an example of a conventional female terminal, a female terminal described in japanese patent application laid-open No. 2014-53205 (patent document 1) is known. The female terminal is manufactured by pressing and bending a metal plate. Further electroplating the processed female terminal. The female terminal has a square-cylindrical box portion into which the male tab terminal is inserted and a conductor crimping portion for crimping a conductor of the power supply line on the rear side of the box portion. The box portion is provided with a plate spring and a protruding piece receiving portion inside. The plate spring is provided on an upper wall of the inside of the box portion and elastically contacts the male tab terminal. The protruding piece receiving part is arranged on the lower wall in the box part and contacts with the male protruding piece terminal.

The male tab terminal is manufactured by pressing and bending a metal plate. The processed male tab terminal is further subjected to plating treatment. The male tab terminal has a rod-shaped male side body portion.

When the male body is inserted into the box portion of the female terminal, the male body is sandwiched between the plate spring and the protruding piece receiving portion. Thereby, the male tab terminal and the female terminal are elastically contacted and electrically connected.

Disclosure of Invention

problems to be solved by the invention

When the male tab terminal is inserted into the box portion of the female terminal, the male side body portion of the male tab terminal is inserted while being elastically pressed by the leaf spring inside the box portion, and therefore, the plating applied to the female terminal is worn at the contact portion between the male tab terminal and the female terminal. In particular, in the case where the male tab terminal needs to be inserted and removed many times, the wear of the plating layer increases. In order to prevent such plating abrasion, it is generally necessary to reduce the contact pressure of the plate spring of the female terminal. However, when the contact pressure of the plate spring of the female terminal is lowered, there is a problem that: the reliability of connection between the terminals is lowered, and poor connection between the terminals is likely to occur due to vibration or the like.

Means for solving the problems

a female terminal disclosed in the present specification is a female terminal to be fitted to a male terminal, and includes: a box-shaped female body having a top wall and a bottom wall opposed to each other in a vertical direction, into which the male terminal is inserted, and being opened in a front-rear direction; a first contact pressure applying portion provided between the top wall and the bottom wall of the female body portion, the first contact pressure applying portion contacting the male terminal from the top wall side to apply a contact pressure to the male terminal; and a second contact pressure applying portion that is provided at a position vertically opposed to the first contact pressure applying portion, and that is brought into contact with the male terminal from the bottom wall side to apply a contact pressure to the male terminal, wherein a first contact point portion at which the first contact pressure applying portion and the male terminal are brought into contact is arranged offset in a front-rear direction from a second contact point portion at which the second contact pressure applying portion and the male terminal are brought into contact, and a contact pressure applied to the male terminal by the first contact pressure applying portion is lower than a contact pressure applied to the male terminal by the second contact pressure applying portion.

With this configuration, the contact pressure applied to the male terminal from the bottom wall side in the female-side body portion by the second contact pressure applying portion can be set to a high contact pressure, and the contact pressure applied to the male terminal from the top wall side in the female-side body portion by the first contact pressure applying portion can be set to a low contact pressure.

Here, the high contact pressure is a contact pressure at which the contact portions of the female terminal and the male terminal are not electrically disconnected when vibration or the like is applied to the fitted male terminal and female terminal. When the male terminal is inserted into and pulled out of the female terminal in a state where such a high contact pressure is applied to the male terminal, plating applied to contact portions of the male terminal and the female terminal is worn. On the other hand, the low contact pressure is a contact pressure lower than the high contact pressure, and is a contact pressure to the extent that the plating layer applied to the female terminal does not wear at the contact portion between the male terminal and the female terminal even when the male terminal is inserted into and removed from the female terminal.

In this way, the plating layer applied to the female terminal is worn at the second contact point where the second contact pressure applying portion having a high contact pressure contacts the male terminal, but is less susceptible to vibration or the like, and a connection failure between the male and female terminals is less likely to occur. On the other hand, in the first contact point portion where the first contact pressure applying portion having a low contact pressure and the male terminal are in contact with each other, abrasion of the plating layer applied to the female terminal can be prevented, and therefore, abrasion of the plating layer due to multiple times of insertion and removal of the male terminal can be prevented, and conduction can be ensured. Therefore, the plating layer is allowed to wear at the second contact pressure applying portion having a high contact pressure, and the reliability of connection between the terminals can be ensured, and the plating layer is prevented from wearing at the first contact pressure applying portion having a low contact pressure, and conduction can be ensured even if the male terminal is inserted into and removed from the female terminal a plurality of times.

In addition, the first contact pressure applying portion and the second contact pressure applying portion may be arranged in two in a direction intersecting with an insertion direction of the male terminal, and the female terminal may include: a third contact pressure applying portion that is provided between the adjacent first contact pressure applying portions, and that is in contact with the male terminal from the top wall side to apply a contact pressure to the male terminal; and a fourth contact pressure applying portion that is provided at a position vertically opposed to the third contact pressure applying portion, and that is brought into contact with the male terminal from the bottom wall side to apply a contact pressure to the male terminal, wherein a third contact point portion at which the third contact pressure applying portion and the male terminal are brought into contact is arranged at a position shifted in the front-rear direction from a fourth contact point portion at which the fourth contact pressure applying portion and the male terminal are brought into contact, and a contact pressure applied to the male terminal by the third contact pressure applying portion is higher than a contact pressure applied to the male terminal by the fourth contact pressure applying portion.

With this configuration, the male terminal is given a high contact pressure from the bottom wall side by the two second contact pressure applying portions, and is given a high contact pressure from the top wall side by the one third contact pressure applying portion.

For example, when the male terminal is housed in the male housing, the male terminal in the male housing may be rattled in order to facilitate fitting of the male terminal and the female terminal. In the case where the male terminal is caused to have such a rattling state and there is only one pair of the first contact pressure applying portion having a low contact pressure and the second contact pressure applying portion having a high contact pressure, when the male terminal passes through the second contact point portion of the second contact pressure applying portion having a high contact pressure, the male terminal is displaced toward the ceiling wall side by rattling in the male housing, and the male terminal and the first contact pressure applying portion having a low contact pressure come into contact with each other with a high contact pressure and slide. Thereby, the plating layer of the first contact pressure imparting portion becomes worn.

However, as described above, by applying a high contact pressure from the third contact pressure applying portion not only from the bottom wall side but also from the top wall side, even when the male terminal is shaken, the male terminal can be inserted and removed into and from the female body portion without abrasion of the plating layer of the first contact pressure applying portion.

Further, the second contact pressure applying portion may include a second vertical piece extending perpendicularly from the second contact portion toward the bottom wall, and an end surface of the second vertical piece may be brought into contact with the bottom wall by insertion of the male terminal.

With such a configuration, when the male terminal is inserted into the inside of the female-side body portion, the second contact point portion of the second contact pressure applying portion that is in contact with the male terminal is displaced toward the bottom wall. Accordingly, the second vertical piece of the second contact pressure applying portion is also displaced toward the bottom wall, and the end surface of the second vertical piece abuts against the bottom wall. However, since the second vertical piece extends perpendicularly from the second contact portion toward the bottom wall and is therefore hardly flexed, the second contact portion is hardly displaced toward the bottom wall when the second vertical piece abuts against the bottom wall. Therefore, the second contact pressure imparting portion can impart a high contact pressure to the male terminal.

Further, the third contact pressure applying portion may include a third vertical piece extending perpendicularly from the third contact portion toward the ceiling wall, and an end surface of the third vertical piece may be brought into contact with the ceiling wall by insertion of the male terminal.

With such a configuration, the third contact pressure applying portion can apply a high contact pressure to the male terminal, as in the second contact pressure applying portion described above.

Detailed Description

< embodiment >

The present embodiment will be described with reference to fig. 1 to 9.

the female terminal 10 of the present embodiment is formed by punching and bending a copper metal plate. The processed female terminal 10 is further subjected to plating treatment with silver or the like. As shown in fig. 1, the female terminal 10 includes a female-side body 11 and a wire connection portion 18 provided behind the female-side body 11. The female terminal 10 is fitted to a male terminal not shown.

The male terminal is not shown in the drawings, is in the form of a plate, and is formed by punching or the like a metal plate. The processed male terminal is further subjected to plating treatment with silver or the like.

As shown in fig. 5, the female body 11 has a box shape and opens in the front-rear direction. The female-side body 11 has a top wall 12 and a bottom wall 15 facing each other in the vertical direction. In the following description, the fitting direction of the female terminal 10 and the male terminal is defined as the front, and the direction from the bottom wall 15 of the female body 11 toward the top wall 12 is defined as the upper direction.

As shown in fig. 2 and 5 to 7, the top wall 12 includes: two first contact pressure imparting portions 20, the first contact pressure imparting portions 20 imparting a low contact pressure to the male terminal; and a third contact pressure imparting portion 40 imparting a high contact pressure to the male terminal.

Here, the high contact pressure is a contact pressure at which the contact portions of the female terminal 10 and the male terminal do not interrupt the connection when vibration or the like is applied to the fitted male terminal and female terminal 10. When the male terminal is inserted into and removed from the female terminal 10 in a state where such a high contact pressure is applied to the male terminal, the plating layer applied to the contact portion between the male terminal and the female terminal 10 is worn.

On the other hand, the low contact pressure is a contact pressure lower than the high contact pressure, and is a contact pressure to the extent that even if the male terminal is inserted into and removed from the female terminal 10, the plating layer applied to the female terminal 10 at the contact point between the male terminal and the female terminal 10 is not worn.

As shown in fig. 5, the two first contact pressure applying portions 20 are formed to extend rearward through the first base end portion 13, and the first base end portion 13 is folded back inward of the female-side body portion 11 from the front end edge of the top wall 12. The first contact point 21 is provided on the rear end side of the female-side body 11 and is formed in the female-side body 11 so as to protrude downward in an embossed shape. The first contact portion 21 is in contact with a male terminal not shown.

As shown in fig. 2 and 6, the third contact pressure applying portion 40 is disposed between the two first contact pressure applying portions 20. The third contact pressure applying portion 40 includes: a third contact portion 41 that contacts a male terminal not shown; a third inclined portion 42 inclined from the third contact portion 41 toward the first base end portion 13 on the top wall 12 side; and a third vertical piece 43 extending perpendicularly from the third contact portion 41 toward the top wall 12. The third contact portion 41 is provided forward of the first contact portion 21 of the first contact pressure applying portion 20 that applies a low contact pressure. Although the end surface 44 of the third vertical piece 43 does not abut against the top wall 12, when a male terminal, not shown, is inserted into the female body 11, the end surface 44 abuts against the bottom wall 15. When the male terminal is further inserted into the female-side body 11 with the end surface 44 in contact with the ceiling wall 12, the third vertical piece 43 is pressed against the ceiling wall 12 by the male terminal. However, since the third contact point portion 41 extends perpendicularly toward the bottom wall 15, the second contact pressure imparting portion 30 hardly deflects. Therefore, the contact pressure applied to the male terminal by the second contact pressure applying portion 30 becomes a high contact pressure.

As shown in fig. 2 and 5 to 7, the bottom wall 15 includes two second contact pressure applying portions 30 that apply a high contact pressure to the male terminal and one fourth contact pressure applying portion 50 that applies a low contact pressure to the male terminal.

As shown in fig. 2, 5, and 7, the two second contact pressure applying portions 30 are provided at positions vertically opposed to the first contact pressure applying portions 20. As shown in fig. 5, the two second contact pressure applying portions 30 include: a second contact portion 31 that contacts a male terminal not shown; a second inclined portion 32 inclined from the second contact portion 31 toward the second base end portion 16 connected to the bottom wall 15; and a second vertical piece 33 extending perpendicularly from the second contact portion 31 toward the top wall 12. The end surface 34 of the second vertical piece 33 does not abut on the bottom wall 15, but when a male terminal, not shown, is inserted into the female body 11, the end surface 34 abuts on the bottom wall 15. The second proximal end portion 16 is folded back inward of the female-side body portion 11 from the front end edge of the bottom wall 15. The second contact portion 31 is provided forward of a fourth contact portion 51 described later. In this way, the second contact pressure applying portion 30 has the same shape as the third contact pressure applying portion 40, and can apply a high contact pressure to the male terminal.

As shown in fig. 2 and 6, the fourth contact pressure applying portion 50 is provided at a position vertically opposed to the third contact pressure applying portion 40. The fourth contact pressure applying portion 50 is formed to extend rearward through the second base end portion 16. The fourth contact portion 51 is provided on the rear end side of the female-side body portion 11 and is formed to protrude upward in an embossed shape inside the female-side body portion 11. The fourth contact portion 51 is in contact with a male terminal not shown.

As shown in fig. 5, a first excessive deflection preventing portion 14 is provided behind the top wall 12 of the female-side body portion 11. The first excessive deflection preventing portion 14 is formed by knocking a portion of the top wall 12 and ejecting the portion inward of the reverse surface of the top wall 12. Thus, even if the first contact pressure applying portion 20 is deflected upward by insertion and removal of a male terminal, not shown, the first contact pressure applying portion 20 contacts the first excessive deflection preventing portion 14 from below, and the first contact pressure applying portion 20 is prevented from being excessively deflected and plastically deformed. Even if the third vertical piece 43 is pushed rearward by insertion of a male terminal, not shown, in the third contact pressure applying portion 40, the third vertical piece 43 comes into contact with the first excessive deflection preventing portion 14 from the front, and the third contact pressure applying portion 40 is prevented from being excessively deflected and plastically deformed.

As shown in fig. 5, a second excessive deflection preventing portion 17 is provided behind the bottom wall 15 of the female-side body portion 11. The second excessive deflection preventing portion 17 is also formed in the same manner as the first excessive deflection preventing portion 14, and prevents the second contact pressure applying portion 30 and the fourth contact pressure applying portion 50 from being excessively deflected and plastically deformed.

As shown in fig. 5, the wire connecting portion 18 is formed to protrude rearward from the rear end of the bottom wall 15. An electric wire, not shown, is connected to the electric wire connection portion 18, and the female terminal 10 and the electric wire are electrically conducted.

Next, the operation of the present embodiment will be described.

When the male terminal is inserted into the female-side body portion 11 of the female terminal 10, the male terminal comes into contact with the two second contact pressure imparting portions 30 imparting a high contact pressure on the bottom wall 15 side and the third contact pressure imparting portion 40 imparting a high contact pressure on the top wall 12 side, although not shown. Thereby, the male terminal slides with the second contact point portion 31 of the second contact pressure applying portion 30. In addition, the male terminal slides with the third contact point portion 41 of the third contact pressure applying portion 40. Thus, although the plating layers applied to the second contact pressure applying portion 30 and the third contact pressure applying portion 40 of the female terminal 10 are worn away, the electrical connection is not interrupted by vibration as will be described later.

On the other hand, the first inclined portion 22 of the first contact pressure applying portion 20 is provided at a position vertically opposed to the second contact portion 31, and the fourth inclined portion 52 of the fourth contact pressure applying portion 50 is provided at a position vertically opposed to the third contact portion 41. However, since the male terminal is applied with high contact pressure from both the bottom wall 15 side and the top wall 12 side, even if the first inclined portion 22 and the fourth inclined portion 52 have the second contact portion 31 and the third contact portion 41 which are opposed to each other in the vertical direction and which apply high contact pressure, high contact pressure is not applied, and the plating layers applied to the first inclined portion 22 and the fourth inclined portion 52 are not worn.

When the male terminal is further inserted into the female body 11, the male terminal comes into contact with the first contact point 21 of the first contact pressure applying portion 20 and the fourth contact point 51 of the fourth contact pressure applying portion 50, which apply low contact pressures, although not shown. Thereby, the male terminal slides on the first contact portion 21, and the male terminal slides on the fourth contact portion 51. However, since the contact pressure applied to the male terminal by the first contact pressure applying portion 20 and the fourth contact pressure applying portion 50 is low, the plating layers applied to the first contact portion 21 and the fourth contact portion 51 are not worn.

When vibration is applied to the male and female terminals 10, the contact point of the male and female terminals 10 also becomes shaken, but as described above, since the male terminal is given high contact pressure by the two second contact pressure giving portions 30 and the one third contact pressure giving portion 40, the electrical connection between the male and female terminals 10 is continued without interruption.

Even when the male terminal is pulled out from the inside of the female-side body 11, the plating layer is not worn at the first contact point 21 of the first contact pressure applying portion 20 and the fourth contact point 51 of the fourth contact pressure applying portion 50, which apply low contact pressure, in the same manner as in the above-described male terminal insertion. Further, the plating is worn away at the second contact point portion 31 of the second contact pressure applying portion 30 and the third contact point portion 41 of the third contact pressure applying portion 40, which apply high contact pressure. Therefore, even if the plating layer abrasion due to the sliding between the male terminal and the second and third contact pressure applying portions 20 and 30 applying a high contact pressure is allowed, the plating layer abrasion due to the sliding between the male terminal and the first and fourth contact pressure applying portions 20 and 50 applying a low contact pressure can be prevented.

As described above, according to the present embodiment, the contact pressure applied to the male terminal from the bottom wall 15 side in the female body 11 by the second contact pressure applying portion 30 can be set to a high contact pressure, and the contact pressure applied to the male terminal from the top wall 12 side in the female body 11 by the first contact pressure applying portion 20 can be set to a low contact pressure.

Here, the high contact pressure is a contact pressure at which the contact portions of the female terminal and the male terminal 10 are not disconnected from each other when vibration or the like is applied to the fitted male terminal and female terminal 10. When the male terminal is inserted into and removed from the female terminal 10 in a state where such a high contact pressure is applied to the male terminal, the plating layer applied to the contact portion between the male terminal and the female terminal 10 is worn. On the other hand, the low contact pressure is a contact pressure lower than the high contact pressure, and is a contact pressure at which the plated layer applied to the female terminal 10 is not worn at the contact portion between the male terminal and the female terminal 10 even when the male terminal is inserted into and removed from the female terminal 10.

In this way, although the plating layer applied to the female terminal is worn at the second contact point 31 where the second contact pressure applying portion 30 having a high contact pressure contacts the male terminal, it is less likely to be affected by vibration or the like, and poor connection between both the male and female terminals is less likely to occur. On the other hand, in the first contact point portion 21 where the first contact pressure applying portion 20 of low contact pressure contacts the male terminal, the plating layer applied to the female terminal can be prevented from being worn, and therefore, the plating layer can be prevented from being worn by inserting and extracting the male terminal a plurality of times, and conduction can be ensured. Therefore, the second contact pressure applying portion 30 having a high contact pressure allows plating wear and ensures reliability of connection between the terminals, and the first contact pressure applying portion 20 having a low contact pressure prevents plating wear and ensures conduction even when the male terminal is inserted into and removed from the female terminal 10 a plurality of times.

In addition, the male terminal is given a high contact pressure from the bottom wall 15 side by the two second contact pressure applying portions 30, and from the top wall 12 side by the one third contact pressure applying portion 40.

For example, when the male terminal is housed in the male housing, the male terminal in the male housing may be rattled in order to facilitate the fitting of the male terminal to the female terminal 10. In the case where the male terminal is caused to have such a rattling motion and there is only one pair of the first contact pressure applying portion 20 having a low contact pressure and the second contact pressure applying portion 30 having a high contact pressure, when the male terminal passes through the second contact point portion 31 of the second contact pressure applying portion 30 having a high contact pressure, the male terminal is displaced toward the top wall 12 side by rattling within the male housing, and the male terminal is brought into contact with the first contact pressure applying portion 20 having a low contact pressure and slides. Thereby, the plating layer of the first contact pressure imparting portion 20 becomes worn.

However, as described above, by applying a high contact pressure from not only the bottom wall 15 side but also the top wall 12 side by the third contact pressure applying portion 40, even when the male terminal is shaken, the male terminal can be inserted into and removed from the female body portion 11 without abrasion of the plating layer of the first contact pressure applying portion 20.

In addition, when the male terminal is inserted into the inside of the female-side body portion 11, the second contact point portion 31 of the second contact pressure imparting portion 30 that is in contact with the male terminal is displaced toward the bottom wall 15. Accordingly, the second vertical piece 33 of the second contact pressure applying portion 30 is also displaced toward the bottom wall, and the end face of the second vertical piece 33 abuts against the bottom wall. However, the second vertical piece 33 extends perpendicularly from the second contact portion toward the bottom wall, and therefore hardly bends, so that the second contact portion 31 is hardly displaced toward the bottom wall 15 when the second vertical piece 33 abuts against the bottom wall 15. Therefore, the second contact pressure applying portion 30 can apply a high contact pressure to the male terminal.

In addition, the third contact pressure applying portion 40 can apply a high contact pressure to the male terminal, as in the second contact pressure applying portion 30 described above.
