A wiring bridge for switch

Abstract

The present invention discloses a wiring bridge for a switch, including a shell, a terminal and a mounting groove. The shell has a receiving cavity penetrating along the length direction. The receiving cavity is used for fixing the terminal and routing the wiring harness. A left-right symmetrical slider is arranged in the cavity. The slider is used to fix the terminal. A slot is arranged on one side of the slider facing the inner wall of the shell cavity. An auxiliary part is arranged in the slot. The auxiliary part is used for auxiliary movement of the terminal. The roller of the present invention abuts against the inner wall of the shell, and the entire terminal is subjected to the pulling force of the wire. The movement of the terminal is facilitated by the action of the roller. It should be noted that when the roller and the inner wall of the shell are subjected to force, the compression spring is compressed, and the slider moves toward the end, so that there is a gap between the slider and the inner wall of the shell where the roller contacts the inner wall of the shell. This makes it easier to move the entire terminal and avoids directly tearing the wire harness when pulling the wire harness or deforming the terminal pin.

Description

Technical Field

[0001] The invention relates to the field of wiring bridges, and in particular to a wiring bridge for switches. Background Art

[0002] As the power grid's requirements for intelligence are getting better and better, the requirements for the intelligence of switch components are getting higher and higher. It is required that the control of the switch is intelligent, and the control of the switch on and off must be controlled by intelligent components. Due to the limited switch space, the intelligent control components are designed on the bottom plate of the switch, but during the installation and use process, when the terminal needs to be retracted into the wiring groove and the wiring bridge is installed, it is often necessary to adjust the retracted terminal, that is, the terminal needs to be moved and adjusted to the threading port. The conventional adjustment method is to directly pull the wiring harness connected to the terminal to move in the wiring bridge. This operation will cause the wiring harness to be torn off from the terminal. If it is poked from the insertion end of the terminal, the terminal pin will be deformed by force, thereby damaging the terminal pin. Summary of the invention

[0003] An object of the present invention is to provide a switch wiring bridge that solves at least any aspect of the above-mentioned technical problems.

[0004] A further object of the present invention is to avoid the problem of inconvenience in adjusting the terminals after they are placed in the wiring bridge housing.

[0005] Another further object of the present invention is to improve the moving effect of the terminal in the wiring bridge housing to facilitate the adjustment of the terminal position.

[0006] In particular, the present invention provides a wiring bridge for a switch, comprising: a housing, wherein the housing has a receiving cavity penetrating along the length direction, wherein a left-right symmetrical slider is arranged in the cavity, wherein a side of the slider facing the inner wall of the housing cavity is provided with a slot, wherein an auxiliary member is arranged in the slot;

[0007] A terminal, the terminal being disposed in the cavity of the housing and fixed between the sliders;

[0008] The mounting grooves are arranged at four corners of the housing cavity.

[0009] Furthermore, the auxiliary component has a rotating shaft vertically fixed in the slot, and a roller and a pull rod installed on the rotating shaft, the roller and the pull rod are integrally connected, and a preset angle is set between the roller and the pull rod.

[0010] Furthermore, a through hole communicating with the slot is provided in the sliding block, and a pull wire connected with the pull rod is provided in the through hole.

[0011] Furthermore, a compression spring is provided on a side of the sliding block facing the terminal.

[0012] Furthermore, a reverse support member is arranged in the installation groove.

[0013] Furthermore, a through groove is provided in the middle of the accommodating cavity of the shell.

[0014] Technical effects and advantages of the present invention:

[0015] The present invention is to install sliders on both sides of the terminal when in use, clamp and fix the terminal through the sliders, and install the terminal together with the terminal in the shell of the wiring bridge, manually retract the terminal into the wiring bridge, and after the wiring bridge is installed and fixed, when the terminal needs to be adjusted, pull the pull rod by pulling the wire, and an angle is set between the pull rod and the roller. When the pull rod is offset by force, the roller moves toward the inner wall of the shell, and the roller presses against the inner wall of the shell. At the same time, the entire terminal is subjected to the tension of the pulling wire, and the movement of the terminal is facilitated by the action of the roller. It should be noted that when the roller and the inner wall of the shell are subjected to force, the clamping spring is compressed, and the slider moves to the side where the slider is at the end, so that there is a gap between the slider and the inner wall of the shell where the roller contacts the inner wall of the shell. This makes it easier to move the entire terminal and avoids directly tearing the wire harness when pulling the wire harness, or deforming the terminal pin. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The scheme of this embodiment provides a wiring bridge for a switch, including a shell 1, a terminal 2 and a mounting groove 101, wherein the shell 1 has a accommodating cavity penetrating along the length direction, the accommodating cavity is used for fixing the terminal 2 and routing the wiring harness 4, a left-right symmetrical slider 6 is arranged in the cavity, the slider 6 is used to fix the terminal 2, the slider 6 is provided with a groove 601 on one side facing the inner wall of the cavity of the shell 1, an auxiliary part 7 is arranged in the groove 601, and the auxiliary part 7 is used for auxiliary movement of the terminal 2; the terminal 2 is arranged in the cavity of the shell 1, and the terminal 2 is fixed between the slider 6, and the slider 6 has a protrusion that can clamp the terminal 2, as shown in the specific Figure 4 The mounting groove 101 is arranged at the four corners of the housing 1 accommodating cavity, and a pad 1011 for reversely supporting the terminal 2 may be provided in the mounting groove 101, wherein the pad 1011 may be an arc-shaped protrusion made of rubber material.

[0028] It needs to be further explained that if Figures 4 to 7As shown in , the auxiliary component 7 has a rotating shaft 702 vertically fixed in the slot 601, and a roller 701 and a pull rod 703 installed on the rotating shaft 702, the roller 701 is integrally connected with the pull rod 703, and a preset angle is set between the roller 701 and the pull rod 703, and the pull rod 703 and the roller 701 form a shape of a tilting rod, when the pull rod 703 deviates toward the direction of the wiring harness 4, the roller 701 moves toward the inner wall of the shell 1, and the roller 701 is in direct contact with the inner wall of the shell 1. It should be noted that a clamping spring 3 is arranged between the slider 6 and the terminal 2, and the clamping spring 3 presses against both sides of the terminal 2. When the roller 701 is pressed against the inner wall of the shell 1, the force between the terminal 2 and the slider 6 increases, thereby squeezing the clamping spring 3, so that a gap appears between the slider 6 and the inner wall of the shell 1, which is convenient for the sliding of the mixing wheel. At the same time, the pulling force of the pull wire 704 drives the terminal 2 to move, thereby achieving an effect of easy adjustment.

[0029] It should be further explained that a through hole connected to the slot 601 is provided in the slider 6, and a pull wire 704 connected to the pull rod 703 is provided in the through hole. The pull wire 704 is provided at the same end as the wiring harness 4 to facilitate the position adjustment of the terminal 2. The size of the adjustment displacement of the terminal 2 depends on the size of the force pulling the pull wire 704.

[0030] It should be further explained that a compression spring 3 is provided on a side of the slider 6 facing the terminal 2 , the compression spring 3 is located inside the slider 6 , and the compression spring 3 presses against the fixed terminal 2 .

[0031] It should be further explained that a through slot 5 is provided in the middle of the accommodating cavity of the housing 1 , and the through slot 5 is used to facilitate observation of the adjustment degree of the adjustment terminal 2 .

[0032] Working principle of the present invention:

[0033] When in use, first install the sliders 6 on both sides of the terminal 2, clamp and fix the terminal 2 through the sliders 6, and install the terminal 2 together with the terminal 2 in the housing 1 of the wiring bridge, manually retract the terminal 2 into the wiring bridge, and after the wiring bridge is installed and fixed, when the terminal 2 needs to be adjusted, pull the pull rod 703 through the pull wire 704, and an angle is set between the pull rod 703 and the roller. When the pull rod 703 is offset by force, the roller 701 moves toward the inner wall of the housing 1, and the roller 701 presses against the housing 1. The inner wall of the housing 1, and the entire terminal 2 is subjected to the pulling force of the pull wire 704, and the movement of the terminal 2 is facilitated by the action of the roller 701. It should be noted that when the roller 701 and the inner wall of the housing 1 are subjected to force, the compression spring 3 is compressed, and the slider 6 moves toward the end, so that there is a gap between the slider 6 and the inner wall of the housing 1 where the roller 701 contacts the inner wall of the housing 1. This makes it easier to move the entire terminal 2 and avoids directly pulling the wiring harness 4 or deforming the terminal 2 pin.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
