Technical Field

The present invention relates to electrical connectors, and particularly to an electrical connector and a terminal.

Background

Chinese utility model patent publication No. CN202454786U discloses an electrical connector for a docking connector to be plugged in a first direction and a second direction. However, the electrical connector and the mating connector are only one type of mating mode, that is, the mating connector faces the same direction regardless of whether the mating connector is plugged into the electrical connector in the first direction or the second direction. Since there is only one mating mode between the electrical connector and the mating connector, the electrical connector does not have a positioning structure or a locking structure that can provide a positioning function or a locking function in two mating modes.

In addition, when the butting connector is butted with the electric connector, the terminal salient points of the clamping terminals of the electric connector are in contact with the sheet-shaped terminals of the butting connector, the terminal salient points are usually formed in a stamping mode, so that the other side surface opposite to the convex surface is usually in a concave hollow shape, the terminal salient points are easy to shrink and deform after being collided for many times and damage, and the connector cannot be plugged and pulled out for many times. However, in order to overcome the disadvantage that the terminal is easily damaged, there is another terminal in which the clamping terminal does not have a terminal bump, but a first guiding portion and a second guiding portion for guiding the sheet-like terminal to enter are respectively disposed thereon in the first direction and the second direction.

During the mating process of the second connector 2 with the first connector 1 along the front-back direction D1 and along the up-down direction D2, the two stoppers 114 are slidably received in the two guiding slots 212 a. The first jack 112 and the second jack 113 facing different directions of the first connector 1 enable the second connector 2 to be mated with the first connector 1 in different directions, and the stopper 114 of the first connector 1 and the contact surface 214 and the guide groove 212a of the second connector 2 provide stopping and guiding functions no matter the second connector 2 is mated with the first connector 1 in the front-back direction D1 or in the up-down direction D2. When describing the direction of the second connector 2, forward means the direction of the second connector 2 facing relatively to the first connector 1 during mating, and backward means the direction of the second connector 2 facing relatively away from the first connector 1 during mating. In addition, although the number of the stopper 114, the guiding groove 212a, the shoulder 213 and the contact surface 214 is two in this embodiment, it is understood that the number may be one or three or more in other embodiments, and should not be limited to this embodiment.

Referring to fig. 2, 3 and 7 to 9, for the positioning function between the first connector 1 and the second connector 2, the insulation body 11 of the first connector 1 further has a plurality of first positioning structures 117a and a plurality of second positioning structures 115a formed on the inner wall surface of the insertion slot 111, in detail, the plurality of first positioning structures 117a are formed on the rear wall 117, and the plurality of second positioning structures 115a are formed on the bottom wall 115.

When the second connector 2 is mated with the first connector 1 along the front-back direction D1, the mating portion 212 is inserted into the slot 111 from the first receptacle 112, and the third positioning structures 212b and the first positioning structures 117a are correspondingly engaged with each other; when the second connector 2 is mated with the first connector 1 along the up-down direction D2, the mating portion 212 is inserted into the slot 111 from the second insertion opening 113, and the third positioning structures 212b and the second positioning structures 115a are correspondingly engaged with each other. In the present embodiment, the plurality of first positioning structures 117a and the plurality of second positioning structures 115a are positioning concave portions, and the plurality of third positioning structures 212b are positioning convex portions, but in another embodiment, the plurality of first positioning structures 117a and the plurality of second positioning structures 115a may be positioning convex portions, and in this case, the plurality of third positioning structures 212b are positioning concave portions. In addition, in the present embodiment, the number of the first positioning structures 117a, the second positioning structures 115a, and the third positioning structures 212b is four, but in other embodiments, the number of the first positioning structures 117a, the second positioning structures 115a, and the third positioning structures 212b may be one, two, three, or five or more, respectively, and is not limited thereto. With the first positioning structure 117a and the second positioning structure 115a of the first connector 1 and the third positioning structure 212b of the second connector 2, the positioning function can be provided no matter the second connector 2 is mated with the first connector 1 along the front-back direction D1 or along the up-down direction D2.

As for the locking function between the first connector 1 and the second connector 2, the insulating body 11 of the first connector 1 further has two locking recesses 116a formed on the inner wall surface of the slot 111, and in detail, the two locking recesses 116a are formed on the two side walls 116. The two sides of the insulating housing 21 of the second connector 2 in the left-right direction D3 are respectively provided with two elastic locking strips 23, two ends of which are respectively connected with the insulating housing 21 integrally and can be pressed, the two elastic locking strips 23 extend forwards and backwards, each elastic locking strip 23 is provided with a locking protrusion 231 located at the front and a pressing portion 232 located at the back of the locking protrusion 231 and can be pressed. When the second connector 2 is mated with the first connector 1 along the front-back direction D1 and the up-down direction D2, the locking protrusions 231 of the two resilient locking strips 23 are inserted into the two locking recesses 116a, so that the housing 21 of the second connector 2 is locked to the housing 11 of the first connector 1. At this time, when the user presses the pressing portions 232 of the two resilient locking strips 23, the locking protrusions 231 of the two resilient locking strips 23 will be disengaged from the two locking recesses 116a, thereby unlocking the insulative housing 21 of the second connector 2 from the insulative housing 11 of the first connector 1. By the locking protrusions 231 of the flexible locking strips 23 of the second connector 2 and the locking recesses 116a of the first connector 1, a locking function is provided when the second connector 2 is mated with the first connector 1 along the front-back direction D1 and along the up-down direction D2, so as to prevent the second connector 2 from being separated from the first connector 1. Moreover, since the two ends of the flexible locking strip 23 are integrally connected to the insulating case 21, the two flexible locking strips 23 can be prevented from being wound and pulled with other cables. It should be noted that the number of the locking recesses 116a and the number of the elastic locking strips 23 may be only one, or even three or more in other modified embodiments, and the number in this embodiment should not be limited.

Referring to fig. 1 to 3 and 6 to 7, in addition, in the present embodiment, the insulation body 11 of the first connector 1 is formed with two first fool-proofing structures 116b extending along the front-back direction D1 and two second fool-proofing structures 116c extending along the up-down direction D2, specifically, the two first fool-proofing structures 116b are two convex keys respectively formed on the inner side surfaces of the two side walls 116 and extending along the front-back direction D1, the two second fool-proofing structures 116c are two guide grooves respectively formed on the inner side surfaces of the two side walls 116 and extending along the up-down direction D2, and the two guide grooves are communicated with the two latch recesses 116a in the present embodiment. The mating portion 212 of the insulating housing 21 of the second connector 2 is formed with two third fool-proofing structures 212c corresponding to the two first fool-proofing structures 116b, and two fourth fool-proofing structures 212d corresponding to the two second fool-proofing structures 116 c. In detail, the two third fool-proof structures 212c are two key slots extending forward and backward and cooperating with the two first fool-proof structures 116b (the two convex keys), which are defined by the bottoms of the two resilient locking strips 23 and the outer side surface of the abutting portion 212 of the insulating housing 21 together in this embodiment, and the two fourth fool-proof structures 212d are two convex rails extending forward and backward and cooperating with the two second fool-proof structures 116c (the two guide slots), which are formed on the outer side surface of the abutting portion 212 and located above the two resilient locking strips 23 in this embodiment. When the second connector 2 is mated with the first connector 1 along the front-back direction D1, the two first fool-proof structures 116b and the two third fool-proof structures 212c are correspondingly mated with each other, and when the second connector 2 is mated with the first connector 1 along the up-down direction D2, the two second fool-proof structures 116c and the two fourth fool-proof structures 212D are correspondingly mated with each other. The mating relation between the first fool-proof structure 116b and the third fool-proof structure 212c and the mating relation between the second fool-proof structure 116c and the fourth fool-proof structure 212D prevent the mating portion 212 of the insulative housing 21 of the second connector 2 from being erroneously inserted into the slot 111 of the insulative housing 11 of the first connector 1 in the front-rear direction D1 and the up-down direction D2. It should be noted that the number of the first fool-proof structures 116b and the third fool-proof structures 212c, and the number of the second fool-proof structures 116c and the fourth fool-proof structures 212d can be adjusted according to the requirement, and the number thereof can be one or more than three, which should not be limited by the number in this embodiment.

Referring to fig. 2, 4, 10 and 11, each first terminal 12 is a blade-shaped terminal extending along the front-back direction D1 and the up-down direction D2 and has a blade 121. The sheet 121 has a first surface 121a and a second surface 121b opposite to each other, a top edge 121c, a bottom edge 121d, and two side edges 121 e. The sheet body 121 is provided with a convex hull 121f formed on the first surface 121a, two fixing portions 121g formed on the two side edges 121e respectively and extending outward, and a plurality of concave recesses 121h formed on the first surface 121a and the second surface 121b adjacent to the bottom edge 121 d. The bottom wall 115 of the insulating body 11 of the first connector 1 is penetratingly formed with a plurality of first fixing grooves 115b for fixing the plurality of first terminals 12, two fixing portions 121g of each first terminal 12 are clamped in the corresponding first fixing grooves 115b, and the convex hull 121f interferes with the inner wall surface of the corresponding first fixing groove 115 b. The bottom edges 121d of the first terminals 12 are soldered to the circuit board 200, the recesses 121h on the first surface 121a are located between the convex protrusions 121f and the bottom edges 121d, and the recesses 121h can receive solder to prevent solder from climbing too high. In addition, in the present embodiment, the convex hull 121f is formed by stamping and is approximately located between the two fixing portions 121g, so that the second surface 121b is formed with a concave portion 121i corresponding to the convex hull 121f, and the plurality of concave pits 121h located on the second surface 121b are located between the concave portion 121i and the bottom edge 121 d. The convex protrusions 121f interfering with the inner wall surfaces of the first fixing grooves 115b can further increase the holding force between the first terminals 12 and the insulating body 11. Therefore, the design of the convex hull 121f and the plurality of concave pits 121h provides better holding force and avoids the problem of too high tin-climbing during soldering.

Referring to fig. 4, 5 and 12 to 14, the second terminals 22 are holding terminals for holding the first terminals 12, and each second terminal 22 has a butt-joint section 221 and a wiring section 225. The insulating housing 21 of the second connector 2 is formed with a plurality of second receiving grooves 215 from the rear end surface forward, and the front end of the abutting portion 212 of the insulating housing 21 is formed with a plurality of abutting holes 212e respectively communicated with the plurality of second receiving grooves 215 and having an open bottom, the plurality of second terminals 22 are disposed in the plurality of second receiving grooves 215 from the rear to the front, and the abutting sections 221 of the plurality of second terminals 22 are received in the plurality of abutting holes 212 e. When the first connector 1 is mated with the second connector 2, the first terminals 12 of the first connector 1 enter from the corresponding mating holes 212e to be held by the mating segments 221 of the second terminals 22 in the corresponding mating holes 212e for mating with each other. The wiring segment 225 is connected to the rear end of the docking segment 221 and is used for electrically connecting the corresponding conductive wire 300.

In detail, the docking section 221 has a base plate 222 extending forward, and two side plates 223 connected to two sides of the base plate 222. The base plate 222 and the two side plates 223 together define a mating space 224 into which the first terminal 12 extends and which has a pair of forwardly facing mating ports 224 a. Each side plate 223 has a frame 223a, at least one elastic arm 223e, and a plurality of contact portions 223h extending into the mating space 224. Each frame 223a has a side frame strip 223b spaced apart from and arranged on the substrate 222, and a front frame strip 223c and a rear frame strip 223d connecting the side frame strip 223b and the substrate 222 and spaced apart from and arranged on the front and rear sides of each other. The at least one elastic arm 223e is formed by extending from the rear frame strip 223d toward the front frame strip 223 c. One of the contact portions 223h of each side plate 223 is formed at the side frame strips 223b of the two side plates 223, and the rest of the contact portions 223h are formed at the at least one elastic arm 223 e. The frame 223a of the side plates 223 provides a contact portion 223h for contact, increases the structural strength of the terminal as a whole, and simultaneously protects the at least one elastic arm 223 e. The distances between the contact portions 223h and the pair of interfaces 224a are at least two different lengths, so that the spark tendency during hot plug can be generated only in the contact portion 223h closest to the pair of interfaces 224a, thereby preventing the spark during hot plug from affecting the other contact portions 223h, and the contact portions 223h having different distances from the pair of interfaces 224a can reduce the insertion force during docking. Further, the contact resistance between the first terminal 12 and the second terminal 22 can be reduced by the plurality of contact portions 223h of the two side plates 223.

The contact portion 223h of the at least one resilient arm 223e is adjacent to the pair of interfaces 224a than the contact portion 223h of the side frame 223b, and the contact portion 223h of the at least one resilient arm 223e is formed at the end of the at least one resilient arm 223 e. In detail, in the embodiment, the elastic arm 223e includes a first elastic arm 223f and a second elastic arm 223g, the first elastic arm 223f is located between the second elastic arm 223g and the side frame 223b, and the contact portion 223h of the first elastic arm 223f is most adjacent to the pair of interfaces 224a, that is, the distances between the contact portion 223h of the first elastic arm 223f, the contact portion 223h of the second elastic arm 223g, and the contact portion 223h of the side frame 223b and the pair of interfaces 224a are different, so as to further reduce the insertion force of the butt joint. In addition, since the contact portion 223h of the first elastic arm 223f, the contact portion 223h of the second elastic arm 223g, and the contact portion 223h of the side frame strip 223b are first in contact with the first terminal 12, and finally in contact with the contact portion 223h of the side frame strip 223b, the contact portion 223h of the side frame strip 223b and the contact portion 223h of the second elastic arm 223g can be used as a main contact which is less affected by a spark, and the contact portion 223h of the first elastic arm 223f can be used as a sub contact. In an alternative embodiment, only one of the elastic arms 223e may be adjacent to the pair of interfaces 224a than the contact portion 223h of the side frame strip 223b, for example, only the contact portion 223h of the first elastic arm 223f or the contact portion 223h of the second elastic arm 223g is adjacent to the pair of interfaces 224a than the contact portion 223h of the side frame strip 223 b. In the embodiment, the first elastic arm 223f and the second elastic arm 223g are connected to the frame 223a and surrounded by the frame 223a, but in a modified embodiment, one of the first elastic arm 223f and the second elastic arm 223g may be formed outside the frame 223a, that is, one of the first elastic arm 223f and the second elastic arm 223g may not be surrounded by the frame 223a, in this embodiment, one of the first elastic arm 223f and the second elastic arm 223g that is not surrounded by the frame 223a may not be connected to the frame 223a, and therefore, the embodiment of the embodiment should not be limited.

Referring to fig. 13 and 15, in the present embodiment, a stop portion 223i is formed between the ends of the back frame strips 223d of the two side plates 223 far away from the substrate 222 and is opposite to the substrate 222 at an interval. A snap spring arm 215a is disposed in the second receiving slot 215 of the insulating housing 21 of the second connector 2, and when each second terminal 22 is inserted into the corresponding second receiving slot 215, the stop portion 223i is snapped into the snap spring arm 215a, so that the second terminal 22 is held in the second receiving slot 215.

Referring to fig. 1, 6, 16 and 17, each of the body 121 of each first terminal 12 is formed with a guiding edge 121j at the side edge 121e facing the first inserting hole 112 and the top edge 121c facing the second inserting hole 113, and the guiding edge 121j can reduce the insertion force between the second terminal 22 and the first terminal 12 when the second connector 2 is mated with the first connector 1 along the front-back direction D1 or the up-down direction D2, so as to make the mating smoother.

In summary, in the electrical connector 100 of the present invention, the first receptacle 112 and the second receptacle 113 of the first connector 1 facing different directions enable the second connector 2 to mate with the first connector 1 along different directions, and the stopper 114 of the first connector 1 and the contact surface 214 and the guide groove 212a of the second connector 2 provide stopping and guiding functions no matter the second connector 2 mates with the first connector 1 along the front-back direction D1 or along the up-down direction D2. In addition, the first positioning structure 117a and the second positioning structure 115a of the first connector 1 and the third positioning structure 212b of the second connector 2 can provide the positioning function when the second connector 2 is mated with the first connector 1 along the front-back direction D1 or along the up-down direction D2. Furthermore, the locking protrusion 231 of the flexible locking strip 23 of the second connector 2 and the locking recess 116a of the first connector 1 provide a locking function when the second connector 2 is mated with the first connector 1 along the front-back direction D1 and along the up-down direction D2, so as to prevent the second connector 2 from being separated from the first connector 1. Moreover, since the two ends of the flexible locking strip 23 are integrally connected to the insulating casing 21, the flexible locking strip 23 can be prevented from being wound and pulled with other cables. Secondly, the design of the convex hull 121f and the plurality of concave pits 121h provides better holding force and avoids the problem of too high tin-climbing during soldering. Finally, the frame 223a of the side plates 223 provides a contact portion 223h for contact, thereby increasing the structural strength of the entire terminal and also protecting the elastic arm 223 e. Since at least two different lengths are provided between the contact portions 223h and the pair of interfaces 224a, the spark tendency during hot plug can be generated only at the contact portion 223h closest to the pair of interfaces 224a, thereby preventing the spark during hot plug from affecting the other contact portions 223h, and the contact portions 223h having different distances from the pair of interfaces 224a can reduce the insertion force of the butt joint.

The above description is only exemplary of the present invention, and should not be taken as limiting the scope of the invention, which is defined by the appended claims and their equivalents.
