In order to eliminate the fit clearance between the anti-drop mechanisms and ensure that the socket outer frame 2.1 and the plug outer frame 3.1 are combined more tightly and not loosened, expansion salient points 2.1.7 are arranged on the socket outer frame 2.1 to support the elastic claw hooks 3.1.4 to be matched with the buckle convex shoulders 2.1.4. Finally, as shown in fig. 28, the plug and the socket are mated, so that the whole link is complete and tightly combined.
The elastic claw hooks arranged on the two sides of the plug outer frame can form an anti-falling mechanism when the elastic claw hooks catch the buckle convex shoulders on the two sides of the socket outer frame, so that the plug component and the socket component in the socket can be tightly combined without loosening.
At the joint of the outer socket frame and the outer plug frame, a plurality of low convex contact points, namely expansion salient points, are arranged on the outer socket frame. The anti-drop mechanism has the function of eliminating the fit clearance between the anti-drop mechanisms and completely tightening the anti-drop mechanisms, so that the socket component and the plug component are connected more tightly and reliably. After the assembly is completed, the socket part and the plug part are integrated.
As can be seen from fig. 27 and 28, the support bars provided on the base plate of the base have two functions. Firstly, after the plug part and the socket part are connected, the plug part is supported by the support bars to prevent the plug part from being suspended, and further, the connecting piece inside the plug part and the socket part can be prevented from being influenced by acting force generated by the dead weight of the plug part and the dead weight of the cable; secondly, the largest gap between the supporting bars is used as a guide groove. When the plug component is to be connected with the socket component in a matched mode, the guide keys on the outer frame of the plug can only be matched with the maximum gaps among the supporting bars, guiding is completed, and the plug component is favorably connected with the socket component in a matched mode.
As shown in fig. 29, arrows in the figure indicate installation directions, and according to practical application requirements, six groove rail fixing holes 1.1.1 are formed in the base substrate 1.1 in the embodiment, wherein the groove rail fixing holes 1.1.1 may include two second through holes or four third threaded holes. The fixed connection can be realized in two modes, one mode is that four third base fixing bolts penetrate through four third threaded holes to tightly push the base substrate against the groove rail; and the other type is that two second base fixing bolts sequentially penetrate through a second through hole on the base substrate and a second fixing through hole on the groove rail, and the back surface on the groove rail is matched with a nut, so that the base substrate is fixed on the groove rail.
When the electrical connector is installed in the vertical groove rail, the weight of the whole electrical connector and the cable is fixed and supported by only the movable buckle 1.2 in the fixed bottom plate assembly, and the requirement on the bearing capacity of the movable buckle 1.2 is high. Due to the fact that the gravity of the cable and the gravity of the connecting piece are large, the electric connecting piece can slide downwards, the cable or the connecting piece can touch other equipment, and unnecessary accidents are caused. To above-mentioned problem, six fixed orificess have been seted up on base substrate to this application, can realize the fixed of two kinds of modes: one way is to use four fixing screws to tightly press against the rail of the slot track; another way is to use two fixing bolts to fix on the back plate of the groove rail. In either way, the electrical connector can be prevented from slipping down. The problem of the electrical connector vertical installation in the groove rail in the past, easy landing has been overcome.
In the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. For the system disclosed by the embodiment, the description is relatively simple because the system corresponds to the method disclosed by the embodiment, and the relevant points can be referred to the method part for description.
