Description

Technical Field

[0001] The utility model belongs to the field of electric connectors, and in particular relates to an electric connector and a connector assembly. Background Art

[0002] In the prior art, the connector assembly mainly includes an electrical connector and a docking connector that matches the electrical connector. The electrical connector can be a cable connector or a board-end connector. The cable connector mainly includes an insulating shell, a circuit board and a cable, etc., and a lock is provided on the insulating shell; the board-end connector mainly includes an insulating body, a conductive terminal group and a metal shell covering the insulating body, etc.

[0003] Due to the design of the shell, the existing electrical connectors generally have problems such as difficulty in demolding, manufacturing and assembly. In addition, there are also problems such as oblique insertion and mis-insertion during docking. Even if the assembly is completed successfully, the retention force of the assembled connector components is not high, the overall reliability of the connector is poor, and the service life is short.

[0004] After the existing connector assemblies are connected through the lock, they are generally unlocked by pressing. The connector assemblies that are unlocked by pressing usually have the following defects: 1. When the board-end connectors are arranged in a very small gap array, the gap between the two connected board-end connectors is very small. At this time, it is difficult for fingers to reach into the gap between the connected cable connectors to pull out the cable assembly, and the operability of the product is affected; 2. Two steps are required to separate the cable connector from the board-end connector. The first step is to press to disengage and unlock the lock, and the second step is to change the holding position to pull the cable connector out of the board-end connector, and the unlocking efficiency is low.

[0005] The cable outlet direction of the existing electrical connector is either parallel to the mating direction or perpendicular to the mating direction. Both horizontal outlet and vertical outlet occupy a large space. Utility Model Content

[0054] Embodiment 1:

[0055] like Figures 1 to 5As shown, an electrical connector provided in this embodiment includes an insulating housing 4, a circuit board 3, a retainer 2, and a cable 1. The circuit board 3 is arranged in the insulating housing 4 and extends forward from the insulating housing 4 to form an insertion portion 31, specifically, it is arranged in the first shell 41 and extends forward from the first shell 41 to form the insertion portion 31. A retainer 2 is arranged inside the insulating housing 4, one end of the cable 1 passes through the retainer 2 and is electrically connected to the circuit board 3, and the other end of the cable 1 is tilted downward from the retainer 2. The angle between the outlet direction of the cable 1 in this embodiment and the docking direction of the insertion portion 31 is an obtuse angle, and the angle between the outlet direction of the cable 1 in this embodiment and the docking direction of the insertion portion 31 is 150°. The cable 1 in this embodiment is tilted downward, and an electrical connector with a desired tilt direction and tilt degree is selected according to the requirements of the use environment. By tilting the outlet, the problem of large space occupation of the existing electrical connectors perpendicular or parallel to the docking direction is solved; and the tilt outlet angle of the cable 1 is maintained by the retainer 2 to ensure that the tilt outlet angle of the cable 1 is stable.

[0056] The retaining member 2 includes a connection retaining portion 21 and a wire outlet retaining portion 22. The connection retaining portion 21 at least covers the electrical connection area between the cable 1 and the circuit board 3, and the other end of the cable 1 obliquely passes through the wire outlet retaining portion 22. The connection retaining portion 21 covers the electrical connection area between the cable 1 and the circuit board 3 to ensure the connection stability between the two. The wire outlet retaining portion 22 maintains the shape of the cable 1 so that the wire outlet is inclined at a desired angle.

[0057] The material of the retainer 2 is polyvinyl chloride, nylon or thermoplastic polyurethane elastomer rubber, which ensures good insulation and stability of the tilt angle of the cable 1.

[0058] The insulating housing 4 includes a first shell 41, a docking portion 42 and an anti-slanting insertion portion 43 formed by protruding forward from the first shell 41, and there are gaps (including a first limiting groove 5, a second limiting groove 6, a third limiting groove 7 and a fourth limiting groove 8) between the anti-slanting insertion portion 43 and the docking portion 42, and between the anti-slanting insertion portion 43 and the insertion portion 31. The docking portion 42 and the circuit board 3 are connected to the docking connector 15, and the anti-slanting insertion portion 43 is provided to prevent the oblique insertion.

[0059] The anti-oblique insertion portion 43 includes a first wall 431, a second wall 432, and a third wall 433. The first wall 431 is arranged above the docking portion 42, the second wall 432 is arranged outside the docking portion 42 and the insertion portion 31, and the third wall 433 is arranged below the insertion portion 31. Through the cooperation between the first wall 431 and the docking portion 42, the cooperation between the second wall 432 and the docking portion 42 and the insertion portion 31, and the cooperation between the third wall 433 and the insertion portion 31, the anti-oblique insertion positioning of different positions at various locations can achieve a good overall anti-oblique insertion effect.

[0060] Among them, at least one of the first wall 431, the second wall 432, and the third wall 433 has a partition 434. The partition 434 of this embodiment is set in the middle of the first wall 431 and the third wall 433, and the second wall 432 is not provided with a partition 434. Through such a setting, the partition 434 of the first wall 431 provides sufficient space for the lock member 11; the second wall 432 has no partition 434, so that the length of the second wall 432 is long enough to stably provide a limiting effect and achieve a good anti-oblique insertion effect; the partition 434 is set in the middle of the third wall 433, so that two left and right third walls 433 arranged at intervals are formed below the insertion portion 31, and they cooperate with the left and right second walls 432 respectively, so as to achieve the required anti-oblique insertion limiting effect. There is no need for the third wall 433 to span the first shell 41, which saves more materials and reduces costs.

[0061] Among them, a first limiting groove 5 and a second limiting groove 6 are formed between the anti-oblique insertion portion 43 and the docking portion 42, the first limiting groove 5 is located above the docking portion 42, and the second limiting groove 6 is located outside the docking portion 42.

The first limiting groove 5 and the second limiting groove 6 are used to achieve the anti-oblique insertion effect from different sides, which is used to achieve the positioning of the outer side wall of the metal shell connected to the docking connection. The third limiting groove 7 and the fourth limiting groove 8 are used to achieve the anti-oblique insertion effect from different sides, which is used to achieve the positioning of the conductive terminal group of the docking connector 15.

[0062] A fifth limiting groove 9 is formed between the insertion portion 31 and the docking portion 42. The fifth limiting groove 9 can form upper and lower limits when the circuit board 3 is docked with the conductive terminal of the docking connector 15, so as to prevent the circuit board 3 from being inserted obliquely.

[0063] The first wall 431, the second wall 432, and the third wall 433 are connected together to form an enclosing structure, enclosing the insertion portion 31 and the docking portion 42. The first wall 431, the second wall 432, and the third wall 433 are connected to each other on each side to form a closed limit on each side.

[0064] The first wall 431 is parallel to the upper end surface of the docking portion 42, the second wall 432 is parallel to the side end surface of the docking portion 42 and the side end surface of the insertion portion 31, and the third wall 433 is parallel to the lower end surface of the insertion portion 31. In this way, the first limiting groove 5, the second limiting groove 6, the third limiting groove 7, and the fourth limiting groove 8 formed can better match the docking connector 15.

[0065] The end of the anti-oblique insertion portion 43 away from the first shell 41 has a guide surface 10. The guide surface 10 plays a guiding role.

The insulating shell 4 is divided into two parts, and the first shell 41 and the second shell 44 are clamped together by the first clamping portion 45 and the second clamping portion 46, which not only simplifies the production process, but also makes assembly more convenient and quick. The ends of the first shell 41 and the second shell 44 abut against each other, directly forming a cavity 47, and the cavity 47 has a large space.

[0068] The device further comprises a locking member 11 disposed on the upper side of the docking portion 42 and a drawstring 12 for pulling the locking member 11 to unlock the device. The unlocking method using the drawstring 12 is convenient for unlocking.

[0069] The second shell 44 has a drawstring hole 13, one end of the drawstring 12 passes through the drawstring hole 13 and is connected to the lock member 11, and the connection is located above the drawstring hole 13. By providing the drawstring hole 13 and the drawstring 12, the drawstring 12 can be pulled to achieve rapid unlocking and removal of the electrical connector. When in use, the drawstring 12 is pulled, and the lock member 11 is pulled downward to be unlocked.
