[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0028] like Figure 1-Figure 8 As shown, a relay installation mechanism proposed in one embodiment of the present application includes:

[0029] The relay housing 1 has a wiring chamber 2 inside, and the wiring chamber 2 is used to place electrical components;

[0030] A plurality of wiring assemblies 3 are respectively arranged at both ends of the relay housing 1. The wiring assembly 3 includes a wiring shell 301 with an opening at one end. A conductive sheet 302 is arranged at the inner bottom of the wiring shell 301. A conductive rod 303 with an end extending into the wiring cavity 2 is connected to the conductive sheet 302. The conductive sheet 302 and the conductive rod 303 are both made of copper. The free end of the conductive rod 303 is electrically connected to the electrical component. An adjusting column 3010 is rotatably penetrated at the top of the wiring shell 301. A slot 305 is arranged at the bottom of the adjusting column 3010. The slot 305 is provided with a The movable plug is provided with an insertion rod 306. Preferably, the cross-section of the slot 305 is rectangular, and one end of the insertion rod 306 located in the slot 305 is configured with a rectangular block, which slides and fits with the slot 305, so that the insertion rod 306 can slide along the slot 305. At the same time, when the adjustment column 3010 rotates, the insertion rod 306 can be driven to rotate synchronously. The bottom end of the insertion rod 306 is connected to a card block 307, and the card block 307 is provided with a card slot 308 for clamping the wire. An elastic member for applying elastic resistance to the insertion rod 306 is provided in the slot 305. The terminal housing 301 is provided with a fixing member 304 for fixing the adjusting column 3010. When the wire is installed and connected, the wire core is inserted into the terminal housing 301, and the wire core is inserted into the card slot 308 and overlapped with the conductive sheet 302. The card block 307 is pressed and held on the wire core by the elastic member 309 (preferably, the card block 307 is a hard insulating rubber block, and the bottom end of the card block 307 does not contact the conductive sheet 302), so that the wire core is effectively attached to the conductive sheet 302, and then the adjusting column 301 is rotated. 0. Since the wire core is clamped in the slot 308, when the adjusting column 3010 rotates, the wire core will be spirally coiled, and finally the adjusting column 3010 will be fixed by the fixing member 304. The overall structure of the device clamps the wire core through the slot 308, and then the adjusting column 3010 is rotated to spirally coil the wire core to fit the conductive sheet 302, and finally the elastic member 309 is used to elastically press and hold, so as to connect the wire core with the conductive sheet 302. The spiral coiling cooperates with the elastic pressing and holding to effectively connect the wire and the conductive sheet 302, thereby improving practicality.

[0031] like Figure 4As shown, in some embodiments, the elastic member 309 includes a resistance spring 3091 arranged in the slot 305, and the elastic resistance of the resistance spring 3091 is utilized to apply an elastic resistance force to the insertion rod 306, so that the block 307 applies an elastic pressing force to the wire core, and a slide plate 3092 overlapping with the resistance spring 3091 is slidably inserted in the slot 305, and a linkage member 3093 is arranged in the wiring shell 301. When the adjusting column 3010 rotates, the linkage member 3093 drives the slide plate 3092 to slide along the slot 305 and squeeze the resistance spring 3091. Through the set slide plate 3092, when the adjusting column 3010 is twisted to coil the wire core, the linkage member 3093 drives the slide plate 3092 to squeeze the resistance spring 3091, thereby increasing the pressing force of the block 307 on the wire core, and further ensuring the stability of the connection between the wire core and the conductive sheet 302.

[0032] like Figure 7 As shown, in some embodiments, the linkage member 3093 includes a sleeve 30931 fixed on the inner top wall of the wiring shell 301 and coaxial with the adjusting column 3010, a spiral groove 30932 is provided on the outer surface of the sleeve 30931, and a through groove 30933 connected to the slot 305 is provided on the outer surface of the adjusting column 3010. A shaft rod 30934 is provided on the slide plate 3092, and the free end of the shaft rod 30934 slides through the through groove 30933 and the spiral groove 30932 in sequence. When the adjusting column 3010 is twisted to rotate, the slide plate 3092 and the shaft rod 30934 are driven to rotate synchronously. Due to the spiral structure of the spiral groove 30932 and its sliding guidance of the shaft rod 30934, the shaft rod 30934 slides in a spiral manner in the spiral groove 30932, thereby driving the slide plate 3092 to slide vertically along the slot 305, thereby achieving the effect of squeezing the spring 3091.

[0033] like Figure 3As shown, in some embodiments, the fixing member 304 includes a limiting groove 3041 that penetrates and is opened on the adjusting column 3010, a fixing plate 3042 is provided on the wiring shell 301, two sliding rods 3043 are provided on the fixing plate 3042, and a limiting plate 3044 is slidably sleeved on the two sliding rods 3043, and a limiting block that is plugged and matched with the limiting groove 3041 is constructed on the limiting plate 3044, and a limiting spring 3045 sleeved on the sliding rod 3043 is installed between the limiting plate 3044 and the fixing plate 3042. When the adjusting column 3010 is rotated, the limiting plate 3044 is first slid away from the adjusting column 3010. The column 3010 makes the limit block disengage from the limit groove 3041, and makes the limit plate 3044 squeeze the limit spring 3045. After the adjusting column 3010 is rotated and adjusted, the limit plate 3044 is loosened. Under the elastic resistance of the limit spring 3045, the limit plate 3044 slides and resets, so that the limit block is movably inserted in the limit groove 3041, thereby achieving the effect of fixing the adjusting column 3010. It should be noted that since there is only one limit groove 3041 and it is opened on the adjusting column 3010, the adjusting column 3010 can be locked every 180 degrees of rotation. Figure 6 As shown, the adjusting column 3010 is rotated 720 degrees and the wire core is coiled twice before the adjusting column 3010 is fixed.

[0034] like Figure 4 As shown, in some embodiments, a support rod 4 is hinged on the limiting plate 3044, and a bending portion is constructed at the free end of the support rod 4, and the bending portion is engaged with the fixing plate 3042. When the clamping block 307 is used to clamp the wire core and the adjusting column 3010 is rotated to wind the wire core, the bending portion of the support rod 4 can be clamped with the fixing plate 3042 first, so as to temporarily fix the limiting plate 3044 so that it does not interfere with the rotation of the adjusting column 3010. After the adjusting column 3010 is rotated, the clamping of the bending portion of the support rod 4 and the fixing plate 3042 is released, and then the adjusting column 3010 is fixed by the insertion and cooperation of the limiting block and the limiting groove 3041, thereby further improving the convenience of installation.

[0035] like Figure 5 As shown, in some embodiments, guide rods 5 are slidably penetrated on opposite sides of the inner wall of the wiring shell 301, and pressure plates 6 are provided at opposite ends of the two guide rods 5. A holding spring 7 sleeved on the guide rod 5 is installed between the pressure plate 6 and the inner wall of the wiring shell 301. When the core of the wire is spirally wound, as the adjusting column 3010 continues to rotate, the larger the core is wound, the more the wound core will contact the two pressure plates 6. Under the elastic force of the holding spring 7, the two pressure plates 6 will apply an elastic clamping force to the core, further improving the stability of the fixation of the core. It should be noted that the pressure plate 6 is made of a hard insulating rubber plate.

[0036] like Figure 8As shown, in some embodiments, the slot 308 is constructed in an arch shape, and the inner arc surface array of the slot 308 is constructed with a plurality of racks 8. The slot 308 is constructed in an arch shape to increase the contact area with the wire core. The constructed racks 8 are used to increase the contact friction with the wire core, so that the wire core can be better fixed under the elastic pressure and resistance.

[0037] like Figure 3 and Figure 4 As shown, in some embodiments, a closing plate 9 is hinged at the open end of the wiring shell 301, and a wire groove for the wires to pass through is provided at one end of the closing plate 9 away from the hinge point. A first magnetic strip 10 is provided on the wiring shell 301, and a second magnetic strip 11 that magnetically cooperates with the first magnetic strip 10 is provided on the closing plate 9. By setting the closing plate 9 and the opened wire groove, when connecting the wires, the closing plate 9 can be opened around the hinge point to provide a sufficient installation field of view. When the wires are installed, the closing plate 9 is moved around the hinge point to seal the opening of the wiring shell 301, and fixed by the magnetic cooperation of the first magnetic strip 10 and the second magnetic strip 11. At this time, the wires are just located in the wire groove, and the closing plate 9 seals the wiring shell 301 to reduce the exposed space, prevent dust and impurities from entering the wiring shell 301, and ensure the electrical connection between the wire core and the conductive sheet 302.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
