[0033] Referring to Figures 1 to 9 The embodiment of the utility model provides a kind of connector of stable connection, comprising: connector plug 1, PCB board 2, wire harness rubber plug 3, first inner front mould 4, first inner rear mould 5, metal shell 6, tinplate 7 and wire harness 8;
[0034] As Figure 1 Shown, the connector plug 1 of this embodiment is TYPE-C plug, is provided with multiple groups of connecting terminals 11 in connector plug 1, one end of connector plug 1 is in abutment with PCB board 2, and connecting terminal 11 is welded with PCB board 2, and the other end of PCB board 2 away from connecting terminal 11 is inserted with wire harness rubber plug 3, and wire harness 8 is arranged on wire harness rubber plug 3 and is welded with PCB board 2 to realize conduction with connecting terminal 11;
[0035] Tinplate 7 is fixedly connected to the rear side of connector plug 1, for wrapping connector plug 1 end, PCB board 2 and wire harness rubber plug 3 and wire harness 8, and its specific setting is, as Figure 2 Shown, the tinplate 7 of this embodiment is composed of the first shell 71 and the second shell 72 that are symmetrically arranged, and the first shell 71 and the second shell 72 are provided with matched first buckle hole 73 and first buckling piece 74, and when assembling, first buckle hole 73 of first shell 71 is inserted with first buckling piece 74 of second shell 72, and first shell 71 buckling piece and first buckle hole 73 of second shell 72 are inserted, to realize the mutual buckling of first shell 71 and second shell 72, to facilitate the position matching of first shell 71 and second shell 72 when assembling, first shell 71 and second shell 72 are provided with first alignment recess 75 and first alignment protrusion 76 matched with first alignment recess 75, and first alignment recess 75 and first alignment protrusion 76 of the same shell are arranged on both sides of the same shell, and when assembling, the first alignment recess 75 of different shell is matched with the first alignment protrusion 76 of different shell, which can not only improve the efficiency of assembly, but also improve the waterproof and shielding function of tinplate 7.
[0036] First abutment 77 for wrapping connector plug 1 is provided at the front end of tinplate 7, and the shape of first abutment 77 is matched with the shape of connector plug 1, so that they can be more fitted when assembling, and second abutment 78 for wrapping wire harness 8 is provided at the rear end of tinplate 7, and the shape of second abutment 78 is also matched with the shape of wire harness 8, and the edge of second abutment 78 is slightly extended outward to form wrapping part 79, for wrapping wire harness 8, which can improve the stability of wire harness 8 assembly and reduce the bending of wire harness 8 under stress.
[0037] To further strengthen the connection strength and assembly efficiency of tinplate 7 and connector plug 1, in this example, as Figure 4As shown, the rear end of the connector plug 1 is provided with a first protruding part 12, and the inner wall of the tinplate 7 is provided with a first clamping groove 70 matched with the first protruding part 12. When assembled, the first clamping groove can directly wrap the first protruding part 12 to limit it, effectively clamping the connector plug 1, making the connection between the tinplate 7 and the connector plug 1 more firm and not easy to fall off.
[0038] The metal shell 6 of the embodiment is a hollow shell made of metal material, which can be aluminum alloy. The first inner front mold 4 is fixed to the connection between the tinplate 7 and the connector plug 1, and the first inner rear mold 5 is fixed to the connection between the tinplate 7 and the flat cable 8. The metal shell 6 wraps and clamps the first inner front mold 4 and the first inner rear mold 5. The front end of the first inner front mold 4 is provided with a stepped part 42 with a height difference from the front end of the metal shell 6.
[0039] The first inner front mold 4 and the first inner rear mold 5 are both integrally formed plastic members by pouring or injection molding. That is, after the tinplate 7 is installed, the connector can be placed in an injection mold to form the first inner front mold 4 and the first inner rear mold 5 by injection molding. The first inner front mold 4 and the first inner rear mold 5 of the embodiment are respectively arranged at the connection between the tinplate 7 and the connector plug 1 and the connection between the tinplate 7 and the flat cable 8, which can improve the structural rigidity of these two connections, reduce the risk of bending and breaking under stress, and improve the service life of the connector.
[0040] As shown in Figure 6 and Figure 7 , the rear end of the first inner front mold 4 is a plug-in part 41 for plugging into the metal shell 6. The end of the plug-in part 41 is a guide part 411 gradually inclined from inside to outside. Thus, the outer diameter of the guide part 411 is smaller than the inner diameter of the metal shell 6. A second protruding part 43 is arranged between the stepped part 42 and the plug-in part 41. As shown in Figure 8 a, a second clamping ring body 61 is arranged on the inner wall of the front end of the metal shell 6 and abuts against the second protruding part 43. When assembled, the metal shell 6 can directly pass through the guide part 411 to the end of the second protruding part 43, so that the second protruding part 43 cooperates with the second clamping ring body 61 to achieve clamping. This structure can make the assembly more convenient and fast.
[0041] Preferably, in order to reduce the thickness of the metal shell and the first inner front mold 4 after assembly, the height of the stepped part 42 is lower than that of the plug-in part 41. Thus, a relatively thin stepped part 42 can be formed, which can reduce the thickness between the connector plug 1 and the metal shell while ensuring the rigidity of the rear side of the connector plug 1. When used, it can adapt to different electronic products, facilitate the plugging of the connector plug 1, and improve the flexibility and adaptability of use.
[0042] Based on the above, in some preferred embodiments, a second rear outer mold 9 may be additionally provided behind the metal outer shell 6. The second rear outer mold 9 wraps around the first inner rear mold 5 and is then fastened to the metal outer shell 6. The second rear outer mold 9 is a plastic component integrally formed by casting or injection molding. The resulting structure of plastic components on both sides of the intermediate metal outer shell 6 can improve the feel and aesthetics during use, especially since both outer shells can be made of aluminum alloy.
[0043] like Figure 9 As shown, a third convex ring 91 and a fourth convex ring 92 are sequentially provided at the front end of the second rear outer mold 9, and a third engaging groove 93 is formed between the third convex ring 91 and the fourth convex ring 92, as shown. Figure 8 As shown in Figure b, the inner wall of the metal shell 6 at the end away from the first inner front mold 4 is provided with a fourth snap-fit groove 62 that matches the third convex ring 91. During assembly, the second rear outer mold 9 can be directly inserted into the rear end of the metal shell 6, so that the third convex ring 91 is snapped into the fourth snap-fit groove 62, and the rear end portion 63 of the inner wall of the metal shell 6 is placed in the third snap-fit groove 93. This double snap-fit structure can facilitate efficient assembly, has a good connection effect, does not require the setting of other accessories, and further improves the aesthetics. The rear end of the second rear outer mold 9 is provided with a wire part 94. The wire part 94 can protect the ribbon cable 8 connected to the connector, prevent bending at this position from affecting the soldering effect of the ribbon cable 8 and the PCB board 2, and prevent breakage.
[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
