Technical Field

The present invention relates to a transmission conductor holding structure of an electrical connector, and more particularly, to a transmission conductor holding structure of an electrical connector, which has high bonding strength to a resin, high stability of male and female mating, and is not easily loosened and damaged during separation.

Background

The board-to-board connector is used for connecting different circuit boards, and is provided with a socket connector and a plug connector which are respectively arranged on the different circuit boards, so that the circuit boards are mutually connected. The holding structure at the two ends of the socket connector not only can provide a certain protection effect for the insulating colloid, but also mainly aims to strengthen the locking effect of the plug connector so as to achieve the purpose of maintaining the embedded state between the plug connector and the socket connector.

On mobile devices such as smart phones, the size of the board-to-board connector assembly is very small, which results in the reduction of the structural strength and the service life of each connector, and the link between the plug connector and the socket connector is usually not detached after being embedded, and when a user wants to remove the plug connector, the user applies force to the sidewall of the plug connector or directly pulls the circuit board, and no matter the user applies force in the opposite direction of the plugging direction of the plug connector or shakes the plug connector from side to side, each detachment and separation action increases the risk of damage of the board pair, so the above-mentioned holding structure can effectively improve the service life of the board-to-board connector.

However, the above-mentioned board-to-board connector holding structure has the following problems and disadvantages to be improved:

first, the bonding strength between the holding structure and the insulating colloid is insufficient, which causes the holding structure and the insulating colloid to loosen easily when the plug connector is detached.

Second, the stronger the holding structure helps the mating strength of the male and female connectors, the higher the possibility that the holding structure of the receptacle connector is pulled out when the plug connector is detached, and it is difficult to balance the bonding strength and the mating strength.

How to solve the problems and deficiencies of the prior art is a direction in which the authors of the present invention and the related manufacturers engaged in the industry need to research and improve.

With the above description, it can be understood that the structure of the present technology can achieve the advantages of good bonding strength to the colloid, strong stability of the male and female butt joints, and less possibility of loosening and damage during separation according to the corresponding cooperation of the structure, and the detailed description will be described below.

As can be clearly seen from the figure, the electrical connector 100 of the present invention is a female connector of a board-to-board connector, when in use, the female connector 2 is soldered and fixed on a circuit board, so that the opening direction of the accommodating groove 11 of the female connector colloid 1 is upward, so that the male connector 4 is combined in the female connector 2 and the accommodating groove 11 when being plugged, and the key technology of the present invention is the female holder holding structure 3 on the different ends of the female connector colloid 1, wherein the female holder holding structure 3 is made of metal material and has basic anti-collision strength, so as to coat the two ends of the female connector colloid 1 to effectively exert the anti-collision effect.

In addition, the coupling strength of the female housing holding structure 3 of the present invention to the female housing colloid 1 is strengthened by abutting the end plate portion 31, the side plate portion 33, the end latch arm 32, the clamping plate portion 34, and the locking arm 36 from a plurality of surfaces of the female housing colloid 1, respectively. Specifically, the end plate portion 31 is covered and fixed from the upper surface 15 of the female housing colloid 1, the side plate portion 33 is covered and fixed from the outer side surface 14 of the female housing colloid 1, the clamping plate portion 34 is clamped by the outer side surface 14 and the side end surface 13 at the same time, and the clamping action of the clamping plate portion 34 is matched to make the end fastening arm 32 abut and fixed from the inner end surface 12 of the female housing colloid 1 and make the locking arm 36 abut and fixed from the side end surface 13 of the female housing colloid 1, so that the female housing holding structure 3 is made to respectively abut and fix from multiple surfaces of the female housing colloid 1, the bonding strength of the female housing holding structure 3 and the female housing colloid 1 is enhanced, the two sides of the receiving groove 11 adjacent to the side end surface 13 after bonding are the locking arms 36, and each locking arm 36 is provided with a clamping portion 361 in this embodiment, which is a bump, and is used for tight fastening when the male connector 4 is plugged and bonded. The male connector 4 includes a male colloid 41, a plurality of male terminals 42 disposed side by side on the male colloid 41, and two male holding structures 43 disposed on the male colloid 41 and located on opposite sides of the male terminals 42, so that when the male connector 4 is mated with the electrical connector 100, the male holding structures 43 can be accommodated in the accommodating groove 11, and the engaging portions 361 are fixed on the male holding structures 43 in a manner of abutting against each other, thereby enhancing the mating strength of the male and female connectors.

Furthermore, one side of the clamping plate 34 has a downwardly extending protruding leg 35 inserted into the limiting hole 16 of the female housing glue 1, and the limiting hole 16 is a hole with a certain depth or a through hole penetrating through the female housing glue 1, so that when the protruding leg 35 inclines, the wall surface of the limiting hole 16 is used to limit the inclination. Specifically, when the male connector 4 is engaged with the electrical connector 100, since the engaging portion 361 is pressed against the male holding structure 43, the force of the user pulling out the male connector 4 will act on the female holding structure 3 with a high probability, however, since the protruding portion 35 is inserted into the position-limiting hole 16, unless the male connector 4 is pulled out in a direction completely opposite to the insertion direction, the direction of the force applied to the male connector 4 will cause the male connector 4 to tilt if there is a slight deviation, so that the force of the male holding structure 43 acting on the female holding structure 3 is biased to a certain side, further, the end of the protruding leg 35 is blocked by the wall surface of the stopper hole 16 when the protruding leg 35 is inclined, so as to limit the inclination range, prevent the female housing holding structure 3 from loosening from the female housing colloid 1, and thereby reduce the damage of the pulling action of the male connector 4 to the female connector of the electrical connector 100.

As shown in fig. 2, 3 and 5, the bonding strength between the female housing holding structure 3 and the female housing colloid 1 can be enhanced by enhancing the friction force between the end-fastening arm 32 and the side plate 33 to the female housing colloid 1. Specifically, the inner end surface 12 of the socket colloid 1 has a groove 121, and the end-fastening arm 32 has at least one first hook 321 formed thereon, so that when the end-fastening arm 32 is combined with the groove 121, the first hook 321 abuts against the sidewall of the groove 121 to increase the combination strength. In addition, the outer side surface 14 of the female socket colloid 1 has a limit bump 17, one side of the side plate portion 33 extends downward to have a limit pin 331 and a second hook portion 332, the limit pin 331 and the second hook portion 332 are disposed on two sides of the limit bump 17, and are jointly fixed on the limit bump 17, and the second hook portion 332 is used to support the side wall of the limit bump 17, so as to increase the bonding strength.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, so that the present invention is not limited by the accompanying drawings.
