[0025] The utility model provides a connector.

[0026] like Figure 1As shown, the connector provided by the embodiment of the utility model includes an interface shell 10, a circuit board 20, a protective shell 30 and a connecting wire 40. The interface shell 10 is formed into an annular shell with a hollow cavity 11 by an integral molding method. The circuit board 20 is installed in the hollow cavity 11 and connected to the connecting wire 40. The protective shell 30 is covered on the outside of the interface shell 10 and the circuit board 20.

[0027] The interface shell 10 is formed by stretching and deforming a seamless steel tube. Therefore, in the present technical solution, since the interface shell 10 is formed by stretching and deforming a seamless steel tube, there is no gap on the interface shell 10, so that the waterproof performance of the connector can be significantly improved during subsequent use.

[0028] In addition, the circuit board 20 includes a connecting portion 21 exposed outside the interface shell 10 and a plug-in portion 22 accommodated in the cavity 11. The interface shell 10 is provided with an opening 12 arranged opposite to the circuit board 20.

[0029] 40 is welded and connected to the connecting portion 21, the protective shell 30 covers the interface shell 10 and the outside of the circuit board 20, an injection molding flow channel is arranged in the protective shell 30, an inlet for injecting packaging glue is arranged at the top of the protective shell 30, and an outlet is arranged at the bottom of the protective shell 30, the outlet is located above the connecting portion 21, and the inlet and the outlet are both connected to the injection molding flow channel. This technical solution changes the installation process of the connector. After the wires are welded, the protective shell 30 is installed first, and then the packaging glue is injected through the injection molding flow channel arranged on the protective shell 30. Then, when the packaging glue flows to the circuit board 20 and covers the wires, the protective shell 30 will no longer damage the packaging glue, which significantly improves the protection ability of the packaging glue to the wires, thereby improving the service life.

[0030] Please refer to Figure 2 The plug-in portion 22 is provided with a blocking block 23 for separating the plug-in portion 22 into a first connection portion 221 and a second connection portion 222. The number of the connecting wires 40 is two, and the two connecting wires 40 are respectively welded to the first connection portion 221 and the second connection portion 222. In this embodiment, the blocking block 23 blocks the first connection portion 221 and the second connection portion 222 to prevent the packaging glue at the two locations from mixing.

[0031] At the same time, two blocking blocks 24 are also provided on the plug-in portion 22, and the two blocking blocks 24 are respectively arranged at one end of the first connection portion 221 and the second connection portion 222 away from each other. Therefore, the blocking block 24 can block the encapsulating glue that flows down, wherein, after the wires are welded, the protective cover outside the wires can block the opening 12 of the first connection portion 221 or the second connection portion 222 (surrounded by the interface shell 10, the blocking block 23 and the blocking block 24), and form a space with an open top and closed around, so that when the encapsulating glue flows down, the encapsulating glue will not overflow, so that the amount of encapsulating glue flowing down can be quantitatively controlled. And according to the thickness of the wire, different volumes of encapsulating glue flow down, so that the volume of the encapsulating glue is greater than the volume of the cube formed by the plane parallel to the circuit board 20 at the top of the wire, the circuit board 20, the interface shell 10, the blocking block 23, the blocking block 24 and the protective cover of the wire. And the volume of the encapsulating glue is smaller than the volume formed by the plane parallel to the circuit board 20 where the lowest and highest points of the interface shell 10, the blocking block 23, the blocking block 24 and the protective cover of the wire are located. It can be understood that the height of the wire is lower than that of the interface shell 10, the blocking block 23, the blocking block 24 and the protective cover.

[0032] Please refer to Figure 3 , the injection molding runner includes a main runner 33 and two branch runners 34, the first end of the main runner 33 is connected to the inlet, the first ends of the two branch runners 34 are connected to the second end of the main runner 33, and the second ends of the two branch runners 34 are respectively located above the first connection part 221 and the second connection part 222. The protective shell 30 includes an upper shell 31 and a lower shell 32, the circuit board 20 is located between the upper shell 31 and the lower shell 32, the upper shell 31 and the lower shell 32 are detachably connected, and the injection molding runner is arranged on the upper shell 31. In this embodiment, when the upper shell 31 and the lower shell 32 are butt-connected, the outflow outlet of the branch runner 34 needs to correspond to the upper position of the first connection part 221 and the second connection part 222, so that when the packaging glue flows down through the injection molding runner, the glue amount can be accurately positioned and controlled.

[0033] In addition, a mounting strip 50 is provided on the upper shell 31 or the lower shell 32, and mounting holes 51 are provided at both ends of the mounting strip 50. In this embodiment, the connector can be fastened to other fastening holes or fastening bolts of the terminal through the mounting holes 51. Figure 4 In another embodiment, the orientation of the mounting hole 51 may also be set horizontally to adapt to different styles and improve compatibility.

[0034] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
