Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Embodiment 1, as shown in fig. 1 to 4, a product in this technical solution is formed by injection molding, the number of pins of the pin socket plug-in connector is most commonly 48 pins, in the injection molding process, the pins are first assembled with a primary block, and the pins and the primary block are arranged in an interference fit, so that a gap between the pins and a base due to expansion with heat and contraction with cold can be effectively prevented from being formed in the injection molding process, the waterproof effect is good, the product can be more conveniently plugged in an electrical connection process, the conductive connection is more stable, and the conductive performance is good, two positioning devices 13 for positioning during circuit board installation are arranged on the surface of the base, the positioning devices 13 can provide a more intuitive butt joint for connecting with other connectors or circuit boards, when being connected with other connectors or circuit boards, the misplacement device in the end hole 11 can also play a role of preventing incorrect installation of the plug, and grooves for matching and embedding with the misplacement device 14 are arranged on other connectors, and can also play a role in fixing and stabilizing after connection.

Protection part 12 can play certain contact pin root guard action, the condition that the contact pin takes place to warp has been stopped more to the use of dog 2 appears, guarantee that the contact pin has better position degree and depth of parallelism, be convenient for be connected with other connecting terminal, because in actual production and application, the stitch under the contact pin many conditions is longer, the longer contact pin of length receives the exogenic action easily and takes place bending deformation promptly, specifically speaking, place dog 2 between the stable limit of both sides at first, when inserting the caulking groove strip 21 on dog 2 in location side recess 3 again, the contact pin can insert in the plug-in hole portion, until caulking groove strip 21 contacts and supports the fender chimb, at this moment, caulking groove strip 21 can't be again inwards removed in location side recess 3. Meanwhile, in order to position the stopper 2 provided on the pin holder connector, a protrusion may be provided on the pin.

In order to prevent the stopper 2 from accidentally falling from the positioning side groove 3, an anti-falling part can be further arranged at the caulking groove strip 21 and the positioning side groove 3, and if the anti-falling part is buckled with the strip end latch 5 through occlusion between the anti-falling sawtooth 4 and the strip end latch 5, the anti-falling sawtooth 4 and the strip end latch 5 are matched with each other in shape, just like the matching between the tooth groove and the tooth teeth.
