Description

Technical Field

[0001] The utility model relates to the field of switches and sockets, in particular to a wiring terminal mounting structure and a switch and socket. Background Art

[0002] Switches and sockets are generally equipped with terminal blocks to facilitate wiring operations. Current terminals are generally copper stampings, including terminal blocks connected to conductive copper plates. The terminal blocks are generally frame-type structures and are equipped with screws.

[0034] Reference below Figures 1 to 8 The wiring terminal installation structure according to the embodiment of the present invention is described.

[0035] like Figures 1 to 8 As shown, the terminal mounting structure according to the embodiment of the present invention includes: a top cover 100, a bottom cover 200, and a terminal base 300, wherein the bottom cover 200 covers the bottom of the top cover 100; the terminal base 300 is installed between the top cover 100 and the bottom cover 200, and the terminal base 300 is provided with a wire insertion hole 301, and a side wall of the terminal base 300 is provided with an elastic portion 310;

[0036] The bottom cover 200 is provided with a terminal groove 201 which opens upward and is used to install the terminal seat 300. The bottom of the terminal groove 201 is provided with a wire threading hole 203 corresponding to the wire threading hole 301 for the wire to pass through the wire threading hole 301. The surface cover 100 is provided with a downward extending pushing portion 110. The pushing portion 110 is provided with a pushing inclined surface 111. The pushing portion 110 is provided corresponding to the elastic portion 310. When the surface cover 100 and the bottom cover 200 are covered, the pushing portion 110 moves from top to bottom and pushes the elastic portion 310 laterally through the pushing inclined surface 111, thereby elastically pushing the terminal seat 300 to abut against the groove wall of the terminal groove 201, thereby improving the compactness and stability of the installation of the terminal seat 300.

[0037] In some embodiments of the present invention, the elastic portion 310 protrudes from the outer wall of the terminal base 300 to abut against the pressing inclined surface 111 .

[0038] In some embodiments of the present invention, the terminal base 300 is a frame-shaped structure formed by stamping a conductive metal plate, and the elastic portion 310 is stamped from the conductive metal plate.

[0039] Specifically, there is a U-shaped gap between the elastic part 310 and the terminal base 300, and the root of the elastic part 310 is connected to the terminal base 300. During stamping, the elastic part 310 is stamped along the U-shaped gap so that one end of the elastic part 310 is separated from the terminal base 300 to form a cantilever structure, and the elastic force of the metal plate is utilized to make the elastic part 310 have elastic deformation properties.

[0040] It is conceivable that in some embodiments of the present invention, the terminal base 300 may also be an integral casting or manufactured by cutting machine.

[0041] It can be understood that in some embodiments of the present invention, the elastic portion 310 can also be an elastic component such as a metal plate, which is provided on the outer wall of the terminal base 300 by welding or other means.

[0042] like Figure 5 As shown, in some embodiments of the present invention, the elastic portion 310 is provided with a pressure inclined surface 311 corresponding to the pushing inclined surface 111 to further enhance the pushing effect between the elastic portion 310 and the pushing portion 110 .

[0043] Specifically, when the elastic part 310 is stamped and formed, one end of the elastic part 310 is connected to the terminal base 300, and the other end of the elastic part 310 is separated from the terminal base 300, so that the elastic part 310 as a whole has an inclined structure, thereby forming a pressure inclined surface 311 on the outer surface of the elastic part 310.

[0044] It is understandable that in some embodiments of the present invention, the pressure-bearing inclined surface 311 may also be formed on the outer surface of the elastic portion 310 by machining or other methods.

[0045] like Figure 6 、 Figure 7 As shown, in some embodiments of the present invention, the side wall of the terminal slot 201 is provided with an avoidance opening 202 extending from top to bottom, and the elastic portion 310 is provided corresponding to the avoidance opening 202. When the top cover 100 and the bottom cover 200 are covered, the pushing portion 110 is inserted into the avoidance opening 202 from top to bottom and pushes the elastic portion 310 laterally.

[0046] Specifically, the elastic portion 310 corresponds to the avoidance opening 202 , and the avoidance opening 202 can cooperate with the elastic portion 310 to guide the terminal seat 300 into the terminal slot 201 , thereby facilitating the installation of the terminal seat 300 . At the same time, the avoidance opening 202 can also guide the insertion of the pushing portion 110 .

[0047] like Figure 3 、 Figure 4As shown, in some embodiments of the present invention, the terminal seat 300 is electrically connected to an L-shaped conductive member 390, one end of the conductive member 390 is inserted into the wire insertion hole 301 so that it can be conductive with the wire, and the L-shaped conductive member 390 of the avoidance opening 202 is installed along the avoidance opening 202 to the bottom of the bottom cover 200 and is pressed by the terminal seat 300.

[0048] Specifically, in this embodiment, the L-shaped conductive member 390 is used as a switch contact of the switch seat.

[0049] In some embodiments of the present invention, there is a gap between the outer wall of the terminal seat 300 provided with the elastic portion 310 and the inner wall of the terminal groove 201, and the pushing portion 110 is inserted into the terminal groove 201 along the gap between the outer wall of the terminal seat 300 and the inner wall of the terminal groove 201, and the inner wall of the terminal groove 201 is used to improve the pushing effect of the pushing portion 110.

[0050] Specifically, in the above structure, the side wall of the terminal slot 201 may not be provided with the avoidance opening 202, or the outer side wall of the terminal seat 300 provided with the elastic portion 310 corresponds to the inner side wall of the terminal slot 201 without the avoidance opening 202.

[0051] like Figure 8 As shown, in some embodiments of the present invention, the pushing portion 110 is provided with a slide 112 corresponding to the elastic portion 310, and the pushing inclined surface 111 is provided in the slide 112. When the pushing portion 110 and the elastic portion 310 move relative to each other, the elastic portion 310 slides in the slide and presses against the pushing inclined surface 111. The slide 112 makes the matching accuracy of the pushing inclined surface 111 and the elastic portion 310 higher, and the stability of the mutual pushing is higher.

[0052] Specifically, the slideway 112 is an inclined long groove provided on the pushing portion 110 , and the pushing inclined surface 111 is located at the bottom of the long groove.

[0053] like Figure 3 、 Figure 4 、 Figure 8 As shown, in some embodiments of the present invention, the surface cover 100 is provided with a supporting platform 120 corresponding to the terminal groove 201. When the surface cover 100 and the bottom cover 200 are covered, the lower end of the supporting platform 120 is pressed against the upper end surface of the terminal seat 300, thereby improving the stability of the terminal seat 300 during installation.

[0054] like Figure 3 、 Figure 4 、 Figure 8As shown, in some embodiments of the present invention, a plurality of internal pressure blocks 130 are provided at the lower end of the supporting platform 120, and the plurality of internal pressure blocks 130 are distributed corresponding to the openings of the wire insertion hole 301. When the top cover 100 and the bottom cover 200 are covered, the internal pressure blocks 130 can be inserted into the inner side of the opening of the wire insertion hole 301. The position of the terminal seat 300 is positioned by cooperating with the inner side of the opening of the wire insertion hole 301, thereby improving the installation stability of the terminal seat 300.

[0055] like Figure 8 As shown, in some embodiments of the present invention, the outer side of the internal pressure block 130 is set as a slope structure 131. When the surface cover 100 and the bottom cover 200 are covered, the internal pressure block 130 can be inserted into the inner side of the opening of the wire insertion hole 301, and the slope structure 131 abuts against the inner side of the opening of the wire insertion hole 301. Through the setting of the slope structure 131, when the surface cover 100 and the bottom cover 200 are covered, the terminal seat 300 can be guided to move to the set installation position, thereby improving the assembly accuracy.

[0056] like Figure 8 As shown, in some embodiments of the present invention, the middle part of the support platform 120 is a concave structure, which is aligned with the wire insertion hole 301 and the threading hole 203. The concave structure forms a wire avoidance structure, so that a longer wire can be inserted into the wire insertion hole 301. When tightening the screw, it can ensure that the end of the entire screw is pressed against the wire, thereby improving the reliability of the electrical connection.

[0057] like Figure 8 As shown, in some embodiments of the present invention, the supporting platform 120 is a cylindrical structure, and the pushing portion 110 extends downward from the edge of the supporting platform 120 and gradually narrows to form a pushing slope 111 .

[0058] like Figure 7 As shown, in some embodiments of the present invention, the inner wall of the terminal slot 201 is provided with a plurality of ridges 220 extending from top to bottom. When the terminal seat 300 is installed in the terminal slot 201, it abuts against the ridges 220, thereby improving the compactness of the installation of the terminal seat 300.

[0059] Specifically, the ridge 220 is tightly fitted with the outer wall of the terminal seat 300 to achieve the effect of firmly installing the terminal seat 300. The contact between the ridge 220 and the outer wall of the terminal seat 300 can reduce the friction between the two, making it easier for the terminal seat 300 to be installed in the terminal slot 201.

[0060] like Figure 7 As shown, in some embodiments of the present invention, the upper portion of the ridge 220 is a guiding slope to guide the terminal seat 300 to be installed into the terminal slot 201.

[0061] In some embodiments of the present invention, the ridge 220 extends from top to bottom to the bottom of the bottom cover 200 (or the bottom of the terminal slot 201), connecting the side wall of the terminal slot 201 and the bottom of the slot, thereby strengthening the structural strength of the side wall of the terminal slot 201, making it less prone to deformation, etc., and ensuring the stability of the installation of the terminal seat 300.

[0062] The switch socket according to the embodiment of the second aspect of the present invention includes the terminal installation structure of any embodiment of the first aspect of the present invention, which can improve the stability of the installation of the terminal and facilitate the wiring operation of the switch socket.

[0063] Specifically, the terminal base 300 is installed between the surface cover 100 and the bottom cover 200 through the above structure. The terminal base 300 is installed compactly without looseness, so that the wire insertion hole 301 of the terminal base 300 can be accurately aligned with the wire threading hole 203 of the bottom cover 200, thereby improving the accuracy of threading, making it less likely that the wire will be forked, and improving the reliability of the electrical connection.

[0064] Of course, the invention of the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
