DETAILED DESCRIPTION

[0028] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0029] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0030] like Figure 1 The limiting device of this embodiment includes a conductive bracket 2, a spring 1 and an insulating push block 3. A pin is connected to the lower end of the conductive bracket 2. After being assembled into one, it is installed in a Figure 5 A complete connector structure is formed in the insulating shell.

[0031] like Figure 2 As shown, in this embodiment, the conductive bracket 2 has three sides, of which the two opposite sides are limit baffles 2-1, whose main purpose is to limit the horizontal movement of the spring piece 1 and the insulating push block 3, and also to limit the vertical movement range of the insulating push block 3. The bottom of the spring piece 1 is fixedly connected to the conductive bracket 2 by a snap-fit ​​method, and the floating section of the spring piece 1 is arranged in the conductive bracket 2 and is in close contact with one side of the conductive bracket 2. The insulating push block 3 is arranged between the spring piece 1 and the conductive bracket 2, and slides in the conductive bracket 2.

[0032] like Figure 5 As shown, the insulating housing includes an insulating front cover 4 and an insulating rear cover 5, which can be connected and assembled into one body. The entire insulating housing includes a plurality of mounting holes, each of which is used to mount a wiring device. In the mounting hole, the inner diameter of the insulating front cover 4 is smaller than the inner diameter of the insulating rear cover 5, so that the mounting holes of the insulating front cover 4 and the insulating rear cover 5 form a step for locking and limiting, as shown in FIG. Figure 3 As shown in , in order to provide the step with a better locking and limiting effect, the side wall of the insulating rear cover 5 is arranged as an inclined surface, so that the insulating push block 3 can be completely in contact with the inclined surface during the locking process, thereby increasing the plug-in area and improving the force-bearing surface.

[0033] In this embodiment, the most critical point is that the insulating push block 3 can realize the function of automatic limit locking during the movement. A guide groove 3-1 is set on one side of the insulating push block 3. From top to bottom, the spring piece 1 is set in the guide groove 3-1, and the insulating push block 3 slides up and down on the spring piece 1 along the guide groove 3-1. A guide slider 3-2 is set on the other side of the insulating push block 3 opposite to the side where the guide groove 3-1 is set. The guide slider 3-2 is a protruding structure. On the guide bracket 2 opposite to the guide slider 3-2, that is, on the side of the limit baffle 2-1, a protruding protrusion 2-2 is set, and the protrusion 2-2 is in close contact with the guide slider 3-2 of the insulating push block 2.

[0034] like Figure 3 As shown, in the free state, the bottom of the insulating push block 2 is in free contact with the floating end of the spring sheet 1, and the guide slider 3-2 is in free contact with the protrusion 2-2. When the insulating push block 3 is subjected to a vertical thrust, the insulating push block 3 compresses the floating section of the spring sheet 1 downward, and the floating section of the spring sheet 1 begins to deform and simultaneously applies an elastic force to the insulating push block 3. Figure 4 As shown, during the sliding process, the insulating push block 3 uses the protrusion 2-2 as a fulcrum, and after receiving the elastic force of the spring sheet 1, the insulating push block 3 tilts and changes the force direction, so that the top of the insulating push block 3 is axially offset, and the locking step 3-4 at the top of the insulating push block 3 is pressed against the limit step in the insulating shell by the elastic force applied by the spring sheet. During the locking process, the spring sheet 1 provides vertical and horizontal forces to the insulating push block 3, and the insulating push block is locked in the installation hole under the limit of the protrusion 2-2 and the insulating shell.

[0035] If the limit is to be released, use a tool to move the top of the insulating push block 3 so that the locking steps 3-4 of the insulating push block 3 are separated from the insulating front cover 4, changing the position and shape of the insulating push block 3, thereby changing the force direction of the insulating push block 3. The spring piece 1 applies a force in the vertical direction to the insulating push block 3, which can cause it to bounce up quickly.

[0036] Because the conductive support 2 is provided with a limiting groove 2-3, and the corresponding insulating push block 3 is provided with a limiting step 3-3, the limiting groove 2-3 and the limiting step 3-3 cooperate with each other to prevent the insulating push block 3 from falling off from the conductive support 2.

[0037] This embodiment can connect wires to one mounting hole individually, or connect wires to multiple mounting holes simultaneously, so as to achieve synchronous rapid limiting and locking during the connection process.

[0038] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
