The first return spring 48 acts to return the trigger block 50.

As shown in fig. 11, a plurality of barbs 44 are uniformly arranged on one side of the elastic pressing piece 36 through a semicircular plate 72.

In the invention, the barb 44 is arranged on one side of the elastic pressing block 36, so that the purpose of limiting the electric wire 3 is achieved, and the electric wire 3 is not easy to pull out. The semi-circular plate 72 is designed and installed to prevent the elastic pressing block 36 from affecting the limiting effect of the barb 44 on the electric wire 3 when the electric wire 3 is pulled out.

In the invention, if a user forcibly pulls out the electric wire 3, the electric wire 3 can be pulled out, but the wrapping layer 4 on the electric wire 3 is pulled to be damaged, and the wrapping layer 4 needs to be cut again.

As shown in fig. 12, a first telescopic rod 47 is inserted into the first return spring 48, one end of the first telescopic rod 47 is fixedly mounted on the mounting plate 41, and the other end of the first telescopic rod 47 is fixedly mounted on the spring mounting plate 46.

The reset inclined plane 56 is used for facilitating resetting of the fixture block and the L-shaped limit plate 55, and when the L-shaped limit plate 55 limits the fixture block 57, the L-shaped limit plate 55 is in contact with a straight section on the inclined end face of the fixture block 57 for limiting.

As shown in fig. 14, the second telescopic rod 58 is inserted into the third return spring 59, one end of the second telescopic rod 58 is fixedly mounted on the corresponding sliding plate 35, and the other end of the second telescopic rod 58 is fixedly mounted on the end surface of the corresponding first mounting chute 15.

As shown in fig. 4, the insertion groove 26 has a third seal ring 73 therein. The third sealing ring 73 seals the socket housing 70 and the socket 26.

The specific working process is as follows: when the connector designed by the invention is used, if the electric wire 3 meets the requirements, after the electric wire 3 is inserted, the electric core 5 of the electric wire 3 extrudes the corresponding elastic pressing block 36 in the inserting process, so that the elastic pressing block 36 deforms, extrusion force is generated through the deformation of the elastic pressing block 36, the inserted electric core 5 is compressed, and the compression after the electric core 5 is inserted is ensured; after the battery cell 5 is inserted into contact with the trigger inclined plane 52 on the trigger block 50, the battery cell 5 presses the trigger block 50 through the trigger inclined plane 52 to enable the trigger block 50 to slide towards one side away from the battery cell 5, the trigger block 50 slides to drive the second connecting plate 49 to slide, the second connecting plate 49 slides to drive the limiting block 45 to slide, and meanwhile, the first return spring 48 stretches; after the limiting block 45 moves to be separated from the limiting rod 40, the limiting rod 40 loses the limiting on the limiting block 45, at the moment, the battery core 5 which is continuously inserted drives the mounting plate 41 on which the limiting block 45 is mounted to slide towards one side far away from the sliding plate 35 through the elastic pressing block 36, when the L-shaped limiting plate 55 is separated from the clamping block 57 in the sliding process, the L-shaped limiting plate 55 loses the limiting on the clamping block 57, namely loses the limiting on the corresponding sliding plate 35, at the moment, the sliding plate 35 moves downwards under the action of the third return spring 59, the sliding plate 35 moves downwards to drive the two pressing plates 60 and the clamping plate 62 to move downwards, so that the first sealing half rings 64 mounted on the two pressing plates 60 are in contact with the second sealing half rings 65 on the corresponding lower sides and extrude the wrapping layer 4 inserted into the electric wire 3, and the inserted electric; and the sealing strength is provided by the downward force of the third return spring 59; meanwhile, the clamping plate 62 moves downwards to extrude the wrapping layer 4 of the inserted electric wire 3, so that the inserted electric wire 3 is clamped and limited; the two pressing plates 60 and the clamping plate 62 are in sliding sealing effect through the second sealing ring 63; the double sealing by means of the second sealing ring 63, the first sealing half-ring 64 and the corresponding lower second sealing half-ring 65 provides a sealing effect for the inserted electrical line 3.

If the electric wire 3 is thicker than the plug jack, the electric wire 3 cannot be matched with the plug, and the plug cannot play a connecting role; in the case where the electric wire 3 is thicker than the connector insertion hole, whether the electric wire 3 corresponds to the type of the connector can be determined directly by whether insertion is possible.

If the wires 3 are thin relative to the connector insertion holes and the difference is large, the connector cannot perform a clamping connection function on the wires 3 after the wires 3 are inserted.

In the invention, if the electric core 5 of the electric wire 3 meets the requirement, but the wrapping layer 4 of the electric wire 3 is relatively thin, after the electric wire 3 is inserted, the joint can play a certain role in clamping and connecting the electric wire 3, but cannot meet a good sealing effect; the qualified degree that moves down of the relative parcel layer 4 of the degree that slide 35 moved down this moment is great, and fixture block 57 just can move down the downside that L shape triggered the board, if pulling electric wire 3 this moment, electric wire 3 just can carry out small amplitude slip to the joint mutually, and the parcel layer 4 that explains electric wire 3 this moment is relatively thin, and is unsatisfactory, need dial out, and after dialling out, need insert through the electric wire 3 that meets the requirements, resets fixture block 57 the back, inspects again.
