The plugging plate 3 is fixed to the insulating housing 1, one end of the plugging plate 3 extends out from a socket (not shown) of the insulating housing 1 and has a plurality of contact portions for electrically connecting with the mating terminals 81 of the mating connector 200, the other end of the plugging plate 3 is provided with a plurality of welding portions for connecting a plurality of cables 7, and the cables 7 extend outward from the insulating housing 1; the cover body 4 and the insulating shell 1 are mutually fastened and fixed; the inner membrane is arranged in a cavity formed by enclosing the cover body 4 and the insulating shell 1 and is coated and fixed at the joint of the plugboard 3 and the cable 7. The locking member 2 is mounted on the upper portion of the insulating housing 1, and the locking member 2 is used for locking with an outer shell 9 of the mating connector 200 or unlocking and releasing from the mating connector 200, so as to realize stable connection or unlocking separation between the electrical connector 100 and the mating connector 200.

Referring to fig. 4, 5 to 7, the locking member 2 includes two latching portions 21 for locking with the mating connector 200, a connecting portion 22 connecting the two latching portions 21, and a force-receiving portion 23 formed by bending and extending forward from a front end of the connecting portion 22, and the locking member 2 further includes a fixing portion 25 fixed to the insulating housing 1, two U-shaped elastic portions 24 connected between the fixing portion 25 and the connecting portion 22, and a cross member 26 connecting the two U-shaped elastic portions 24. Each latch 21 extends forward and has a protrusion 211 protruding from the upper side of the insulating housing 1. The force-bearing portion 23 includes an extension portion 231 connected to the connecting portion 22, and a folding portion 232 folded and extended downward and backward from the front end of the extension portion 231, and the folding portion 232 and the extension portion 231 form an acute angle. When the force-bearing part 23 is subjected to a downward acting force, the force-bearing part 23 can move downward, directly drive the latching part 21 to move downward or drive the connecting part 22 to indirectly drive the latching part 21 to move downward, so that the latching part 2 is unlocked and released from the butting connector 200; when the acting force on the force receiving portion 23 is removed, the force receiving portion 23 is restored by the U-shaped elastic portion 24.

Referring to fig. 1 and 2, fig. 6 and 7, the upper portion of the insulating housing 1 has a mating plate 16 for mating with the mating connector 200 and inserting into the housing 9 of the mating connector 200, a receiving space 13 for receiving the mating connector 200 is provided below the mating plate 16, and a mating surface 14 is provided behind the receiving space 13. Wherein, the force-receiving portion 23 and the butt-joint plate 16 are disposed at an interval in the up-down direction Z, and projection portions in the up-down direction Z overlap. Since the docking plate 16 is inserted into the housing 9 of the docking connector 200, a portion of the housing 9 will be located above the docking plate 16. Therefore, the U-shaped elastic part 24 is arranged so that the fulcrum of the downward pressing of the locking fastener 2 is back, the force-bearing part 23 extends forwards to the length range of the butt plate 16, so that the force-bearing part 23 can be relatively far away from the U-shaped elastic part 24, and the acting force required by the downward moving of the force-bearing part 23 can be reduced; although the housing 9 occupies the space below the force receiving portion 23, the force receiving portion 23 is bent upward from the connecting portion 22, so that the force receiving portion 23 can be raised upward, and thus more space is provided below the force receiving portion 23 to prevent the force receiving portion 23 from abutting against the housing 9 downward.

Referring to fig. 2, 3 and 7, two bosses 11 are protruded from the upper portion of the insulating housing 1 and spaced apart from each other in the left-right direction Y, a channel 12 is formed between the two bosses 11, and the two bosses 11 are located below the connecting portion 22. Thereby, the connection portion 22 is located above the boss 11, when the force receiving portion 23 is moved downward by an external force, the position of the latching portion 21 is adjusted to be unlocked from the counterpart connector 200, and the downward movement distance of the force receiving portion 23 can be limited by the boss 11. In the process that the locking fastener 2 deforms under an external force, the stress part 23 is bent upwards from the front end of the connecting part 22, so that the stress part 23 can be lifted upwards relative to the connecting part 22, and enough downward moving space below the stress part 23 is ensured to perform elastic deformation; the connecting portion 22 is relatively low and the boss 11 is arranged below the connecting portion 22, the connecting portion 22 is supported by the boss 11 after moving downwards to a certain degree, so that when the stress of the stress portion 23 is too large or the connecting portion 22 directly receives downward acting force, the downward moving distance of the stress portion 23 and the connecting portion 22 can be limited by the abutting joint of the connecting portion 22 and the boss 11, and the lock catch piece 2 can be prevented from being damaged due to excessive deformation. Further, in this embodiment, the top surface of the boss 11 is used to limit the downward movement distance of the force-receiving portion 23, the lower surface of the connecting portion 22 and the top surface of the boss 11 are disposed opposite to each other and spaced from each other in the up-down direction Z, and the distance between the lower surface of the connecting portion 22 and a part of the top surface of the boss 11 in the up-down direction Z gradually decreases from front to back. Therefore, the stress part 23 is allowed to drive the connecting part 22 to move downwards, and further drive the latch part 21 to move downwards to realize unlocking; because the downward movement distance of the position of the connecting portion 22 away from the force-receiving portion 23 is smaller as the connecting portion 22 moves downward, when the connecting portion 22 is pressed down to contact with the boss 11, compared with a case where a larger constant distance is directly set, the boss 11 of the present embodiment can have more area to contact with the connecting portion 22, so as to better support the connecting portion 22. Further, as shown in fig. 3 and 6, the top surface of the boss 11 includes a front inclined surface 111 and a rear horizontal surface 112 connected to each other, the front inclined surface 111 is inclined downward from back to front, and the lower surface of the connecting portion 22 faces the front inclined surface 111 and the rear horizontal surface 112 in the up-down direction Z. The distance between the lower surface of the connecting portion 22 and the top surface of the boss 11 in the up-down direction Z can be gradually reduced by the front inclined surface 111, and in the case that it is ensured that the connecting portion 22 has a sufficient downward movement distance and the inclination of the front inclined surface 111 matches with the inclination of the connecting portion 22 after downward movement, if only the front inclined surface 111 is provided, the front-back length of the boss 11 is smaller, and in this embodiment, the rear horizontal surface 112 is further provided, so that the supporting area of the boss 11 on the connecting portion 22 is increased; in addition, under abnormal stress (for example, being squeezed by an external object during transportation), the rear part of the connecting part 22 may be directly subjected to a downward force, and at this time, the connecting part 22 will directly move downward vertically, and this embodiment can limit the downward movement distance of the connecting part 22 by the rear horizontal surface 112, so as to avoid the damage of the connecting part 22 caused by excessive deformation under abnormal stress. Further, in the front-rear direction X, the force receiving portion 23 extends forward beyond the front end surface 113 of the boss 11, and the front end surface 113 of the boss 11 does not exceed the insertion surface 14. Therefore, on the premise of not affecting the butting connection between the mating connector 200 and the electrical connector 100, the length of the boss 11 in the front-back direction X is extended, and the front end surface 113 of the boss 11 of the embodiment is flush with the plugging surface 14, so that more space can be made for the force receiving portion 23 to move downwards, and the probability of butting between the boss 11 and the mating connector 200 is reduced. Of course, in other embodiments, the front end surface 113 of the boss 11 may be located behind the insertion surface 14. Further, an opening 27 is formed between the cross beam 26 and the connecting portion 22, and the upper surface and the rear end surface 114 of the boss 11 are spaced from the U-shaped elastic portion 24. Therefore, the U-shaped elastic portion 24 of the present embodiment has better elasticity, so as to reduce the stress required by the stress portion 23, and the boss 11 is retracted from the U-shaped elastic portion 24, so as to provide a required deformation space for the U-shaped elastic portion 24, but at the same time, the boss 11 can prevent the U-shaped elastic portion 24 from being excessively deformed, so as to prevent the U-shaped elastic portion 24 from being damaged by being squeezed due to elastic fatigue. In this embodiment, the boss 11 protrudes upward from the upper side surface of the insulating housing 1.

Referring to fig. 1, fig. 2 and fig. 7, the electrical connector 100 further includes a pull strap 6, wherein one end of the pull strap 6 is connected to the force-receiving portion 23 and is sleeved outside the folding section 232. Therefore, an arc-shaped chamfer can be provided for the pull belt 6 through an acute angle formed between the inflection section 232 and the extension section 231, the pull belt 6 is prevented from being scraped off after being pulled for multiple times, and the inflection section 232 can guide the pull belt 6 along the pulling force direction. And compare in turn back section 232 with extension 231 mutually perpendicular, this embodiment can also reduce the risk of the structure that the atress portion 23 atress moved down the time and leaned on its below, and can set up relatively longer turn back section 232, the bending punch forming of being convenient for turn back section 232. The draw tape 6 passes through the channel 12 between the two bosses 11 and extends outwardly at its other end. Therefore, the displacement of the drawstring 6 in the left-right direction Y can be limited by the two bosses 11, the pulling force can be relatively concentrated, the drawstring 6 is prevented from being deviated and inclined when being pulled, the pulling force required by unlocking can be reduced, the stress part 23 can be prevented from being subjected to larger torsion due to the inclined drawstring 6, and the stress part 23 is prevented from being damaged due to torsional deformation. The cross beam 26 of the locking element 2 has a first limiting surface 261 for limiting the upward movement of the pull strap 6, and the first limiting surface 261 is lower than the top surface of the boss 11 in the vertical direction Z, so that in combination with the force-receiving portion 23 being higher than the top surface of the boss 11, the pull strap 6 of this embodiment always maintains a bending angle during pulling, so that a downward component force can be generated when the pull strap 6 is pulled horizontally to pull the force-receiving portion 23, and the bending angle can be maintained even after the force-receiving portion 23 and the connecting portion 22 are moved downward, thereby avoiding that the pull strap 6 tends to be horizontal and is difficult to maintain the downward force-receiving portion 23 when the force-receiving portion 23 is moved downward to a certain position, and avoiding that the force-receiving portion 23 is elastically restored when the latch portion 21 is not unlocked. It should be noted that, in addition to the force-receiving portion 23 being able to release the latch 21 from the mating connector 200 by pulling the pull tape 6, a user may also directly apply a force to the force-receiving portion 23, so as to directly press down the force-receiving portion 23, so as to cause the latch 21 to release from the mating connector 200.
