[0003] In the existing switching device, a separate power-taking board is arranged on the switch body. The power-taking board is inserted and fixed on the switch body or fixed on the switch body through other fixing structures. An elastic structure is arranged on the power-taking board, and the elastic structure is used for making conductive contact with the incoming line terminal to realize the power-taking function at the position of the incoming line terminal.

[0061] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in the present utility model generally represents an "or" relationship between the front and rear associated objects.

[0066] In the embodiments of the present utility model, the same reference numerals represent the same components. And for the sake of simplicity, in different embodiments, the detailed description of the same components is omitted.

[0067] As Figure 1 , Figure 2 and Figure 3 shown, this embodiment provides a switching device, which can be a circuit breaker, a contactor, etc. It includes a switch body 1 and a power-taking board 2. On the premise of ensuring that the power-taking board 2 can be stably fixed on the switch body 1 and can realize the power-taking function, the manufacturing process of the switching device can be simplified, the assembly efficiency of the switching device can be improved, and the production speed can be accelerated.

[0068] Among them, the switch body 1 includes a housing 11 and a wiring terminal 12 disposed in the housing 11. An elastic member 13 is electrically connected to the wiring terminal 12, and at least a part of the elastic member 13 extends out of the housing 11. The power-taking board 2 is clamped between the elastic member 13 and the housing 11, and the power-taking board 2 is provided with a conductive portion 21. The elastic member 13 can conductively abut against the conductive portion 21 under the action of its own elastic force, so as to realize the conductive connection between the wiring terminal 12 and the power-taking board 2.

[0069] The switchgear provided in this embodiment realizes the acquisition of the electrical signal at the position of the connection terminal 12 through the power-taking board 2 arranged outside the switch body 1. When installing the power-taking board 2, the power-taking board 2 is inserted between the elastic member 13 and the housing 11 of the switch body 1. The elastic member 13 cooperates with the housing 11 of the switch body 1 under the action of its own elastic force to jointly clamp the power-taking board 2, so that the power-taking board 2 is stably installed on the switch body 1. Moreover, the elastic member 13 abuts against the conductive part 21 on the power-taking board 2 under the action of its own elastic force (see Figure 2 and Figure 6 ), enabling the conductive part 21 to be electrically connected to the connection terminal 12 through the elastic member 13, realizing the power-taking function of the power-taking board 2. Since the elastic member 13 has a certain pressing force on the conductive part 21, the contact between the elastic member 13 and the conductive part 21 can be ensured to be stable, reducing the contact resistance and improving the power-taking stability and reliability. Moreover, the elastic member 13 abuts against the conductive part 21 with a certain elastic force, avoiding rigid contact with the conductive part 21 and preventing wear of the conductive part 21.

[0070] By arranging the elastic member 13 on the connection terminal 12 and making at least part of the elastic member 13 extend out of the housing 11 of the switch body 1, the switchgear can not only clamp and fix the power-taking board 2, but also realize the electrical connection between the connection terminal 12 and the power-taking board 2, without setting other structures for fixing the power-taking board 2 on the switch body 1, which can simplify the manufacturing process of the switchgear, improve the assembly efficiency of the switchgear, and speed up the production speed.

[0071] See Figure 3 , a connection post 15 and a connection frame 16 are also arranged in the housing 11. The connection terminal 12 extends into the connection frame 16, and the connection post 15 is threadedly connected to the connection frame 16. After the lead wire enters the connection frame 16 through the connection port on the housing 11, the connection post 15 is screwed to press down the connection terminal 12, pressing the connection terminal 12 against the lead wire to realize wiring.

[0072] In the switchgear, the power supply or voltage signal is usually collected at the incoming line terminal to realize the intelligent control of the switchgear. The connection terminal 12 in this embodiment is specifically an incoming line terminal, and an incoming line terminal is arranged at each connection port of the switchgear. The power-taking function of the power-taking board 2 can be realized through the elastic member 13 arranged on the incoming line terminal. It can be understood that if the switchgear includes multiple incoming line terminals, an elastic member 13 is electrically connected to each incoming line terminal, and the number of the conductive parts 21 on the power-taking board 2 is adaptively set according to requirements. For example, if the power-taking board 2 needs to collect the electrical signals on four incoming line terminals, four conductive parts 21 are arranged on the power-taking board 2, and are in conductive contact with the four elastic members 13 one by one.

[0073] In this embodiment, the conductive part 21 is a conductive pad arranged on the power-taking board 2.

[0074] See Figure 3 、 Figure 4 and Figure 5 , a first through-hole 111 is provided on the housing 11, and the elastic member 13 passes through the housing 11 through the first through-hole 111 to jointly clamp the power-taking plate 2 with the housing 11.

[0075] See Figure 2 and Figure 7 , the elastic member 13 includes a connecting piece 131 and a clamping piece 132. Among them, the connecting piece 131 is electrically connected to the terminal 12 to realize the electrical connection of the entire elastic member 13 with the terminal 12. The clamping piece 132 is bent and connected to the connecting piece 131 and abuts against the conductive part 21. The bent connection between the clamping piece 132 and the connecting piece 131 enables the entire elastic member 13 to have a certain elastic deformation ability. When the connecting piece 131 is fixed on the terminal 12, the clamping piece 132 can elastically deform relative to the connecting piece 131 and the terminal 12, so that the clamping piece 132 can provide a certain clamping force to firmly clamp the power-taking plate 2, making the power-taking plate 2 abut against the housing 11 of the switch body 1 with a certain pressure, improving the installation stability of the power-taking plate 2.

[0076] Furthermore, the clamping piece 132 includes a bent portion 1321 and a contact portion 1322, and the contact portion 1322 is connected to the connecting piece 131 through the bent portion 1321.

[0077] Among them, the bent portion 1321 extends in an arch shape, and the bent portion 1321 protrudes away from the housing 11, which is used to realize the bent connection between the clamping piece 132 and the connecting piece 131, enabling the clamping piece 132 to elastically deform relative to the connecting piece 131, and ensuring a smooth transition at the connection, avoiding stress concentration, and preventing the connection between the clamping piece 132 and the connecting piece 131 from breaking.

[0078] See Figure 4 , the contact portion 1322 extends in an arch shape, and the contact portion 1322 protrudes toward the housing 11 and abuts against the conductive part 21. One side of the contact portion 1322 facing the housing 11 is an arched surface, which can prevent wear and scratch of the conductive part 21 when elastically abutting against the conductive part 21. In addition, since the contact portion 1322 protrudes toward the housing 11, there is a gap between one end of the contact portion 1322 far from the bent portion 1321 and the housing 11. The existence of this gap enables the power-taking plate 2 to be smoothly inserted between the housing 11 and the clamping piece 132 of the elastic member 13 through this gap. Moreover, one end of the contact portion 1322 far from the bent portion 1321 has a guiding arched surface, which can play a certain guiding role for the power-taking plate 2 entering between the elastic member 13 and the housing 11.

[0079] Moreover, the bent portion 1321 and the contact portion 1322 extending in an arch shape can increase the strength of the elastic member 13 to a certain extent. Exemplarily, both the bent portion 1321 and the contact portion 1322 extend in an arc shape or an elliptical arc shape.

[0080] See Figure 7 , the connecting piece 131 includes a first connecting section 1311 and a second connecting section 1312. The first connecting section 1311 is attached to and electrically connected to the terminal 12, ensuring stable contact between the connecting piece 131 and the terminal 12, reducing the contact resistance, and ensuring good electrical conductivity. The second connecting section 1312 is spaced from the terminal 12. Its first end is bent and connected to the first connecting section 1311, and the second end of the second connecting section 1312 extends out of the first through-hole 111 on the housing 11 and is bent and connected to the clamping piece 132. Specifically, the second end of the second connecting section 1312 is connected to the contact portion 1322 through the bent portion 1321. The bent connection between the second connecting section 1312 and the first connecting section 1311 enables the second connecting section 1312 to have a certain elastic deformation ability relative to the first connecting section 1311, thereby improving the elastic deformation ability of the entire elastic member 13.

[0081] Further, it is defined that the portion of the terminal 12 connected to the elastic member 13 extends in a first direction, and its thickness direction is the second direction, and the first direction is perpendicular to the second direction. Both the first connecting section 1311 and the second connecting section 1312 are substantially parallel to the terminal 12, that is, they extend in the first direction, and the clamping piece 132 extends substantially in a direction perpendicular to the second connecting section 1312, that is, it extends in the second direction, so that the entire elastic member 13 has the ability to elastically deform in the first direction and the ability to elastically deform in the second direction. Specifically in Figure 4 , by operating the clamping piece 132, it can be elastically deformed in the left-right direction and can also be elastically deformed slightly in the up-down direction.

[0082] See Figure 7 , an installation groove 121 is recessed in the terminal 12, and the first connecting section 1311 is clamped in the installation groove 121. On the one hand, when installing the elastic member 13 on the terminal 12, the existence of the installation groove 121 plays a positioning role; on the other hand, the clamping fit between the first connecting section 1311 and the installation groove 121 can improve the stability of the elastic member 13 after being installed on the terminal 12 and prevent the elastic member 13 from shifting.

[0083] In some embodiments, the first connecting section 1311 is welded to the terminal 12 to ensure stable connection and achieve electrical connection between the two.

[0084] In other embodiments, see Figure 7, on the wiring terminal 12, riveting posts 122 are provided on the bottom wall of the installation groove 121. Riveting holes are provided on the first connection section 1311. The riveting posts 122 pass through the riveting holes of the first connection section 1311 and are riveted after passing through, so as to realize the riveting of the elastic member 13 on the wiring terminal 12.

[0085] Optionally, the elastic member 13 includes at least two clamping pieces 132, and there is a gap between adjacent clamping pieces 132, which can further improve the contact stability between the elastic member 13 and the conductive part 21.

[0086] In this embodiment, each elastic member 13 includes two clamping pieces 132, and the contact parts 1322 of the two clamping pieces 132 are both abutted against the conductive part 21 to ensure stable contact with the conductive part 21.

[0087] In this embodiment, the elastic member 13 is of an integral structure and is formed by processes such as bending and cutting, so that while having sufficient elastic deformation ability, it also has sufficient strength and can simplify the production steps.

[0088] The elastic member 13 is made of a conductive metal material. Exemplarily, the elastic member 13 is made of a copper sheet or a copper alloy sheet and has better conductivity.

[0089] It can be understood that this embodiment only exemplarily shows the shape and structure of the elastic member 13. In other embodiments, the shape and structure of the elastic member 13 may not be the same as Figure 4 and Figure 7 the shown structure. For example, the connecting piece 131 of the elastic member 13 is a flat sheet, and the clamping piece 132 is also a flat sheet. The whole elastic member 13 is generally L-shaped, and the clamping piece 132 is located outside the housing 11, and it can also realize clamping the power-taking board 2 and contacting the conductive part 21 on the power-taking board 2. Further, contact protrusions or contact elastic pieces can be provided on the side of the clamping piece 132 facing the housing 11 to contact the conductive part 21 on the power-taking board 2 more stably.

[0090] See Figure 2 、 Figure 5 and Figure 6 , one or more positioning holes 24 are provided on the power-taking board 2, and positioning posts 113 corresponding to the positioning holes 24 on the power-taking board 2 are provided outside the housing 11. The positioning posts 113 pass through the corresponding positioning holes 24 to realize the positioning of the power-taking board 2 on the housing 11 and can increase the stability of the power-taking board 2 after being installed on the housing 11.

[0091] See Figure 2 and Figure 8, the switchgear further includes a housing 3. The housing 3 is detachably connected to the housing 11 and covers the power-taking board 2, playing a role in protecting the power-taking board 2 from dust, moisture, etc. The housing 3 abuts against the side of the elastic member 13 facing away from the power-taking board 2, so that the elastic member 13 abuts against the conductive portion 21 with greater pressure. On the one hand, it further improves the clamping stability of the power-taking board 2, and on the other hand, it can improve the contact stability between the elastic member 13 and the conductive portion 21, preventing poor contact between the two.

[0092] See Figure 4 and Figure 7 , the portion of the elastic member 13 extending out of the housing 11 further includes an extension portion 1323. The extension portion 1323 is connected to one end of the contact portion 1322 away from the connecting piece 131, and the extension portion 1323 is spaced from the power-taking board 2. Combining Figure 8 and Figure 9 , the inner wall of the housing 3 is convexly provided with an abutting rib 31. The abutting rib 31 abuts against the side of the extension portion 1323 facing away from the power-taking board 2, so that the contact portion 1322 abuts against the conductive portion 21 more stably, realizing stable electrical conduction contact between the elastic member 13 and the conductive portion 21.

[0093] See Figure 9 , exemplarily, the abutting rib 31 includes a first rib 311 and two second ribs 312 arranged at intervals. The second ribs 312 are vertically connected to the first rib 311. The arrangement direction of the two second ribs 312 is the same as the arrangement direction of the two clamping pieces 132 in the elastic member 13. The extension portions 1323 of the two clamping pieces 132 respectively abut against the first rib 311 and the corresponding second rib 312.

[0094] Exemplarily, the housing 3 can be installed on the housing 11 through a snap structure; and / or, the housing 3 is connected to the housing 11 through a fastener 4. See Figure 9 , the housing 3 is provided with a fixing post 32. See Figure 5 and Figure 6 , the housing 11 is provided with a fixing hole 114, and the power-taking board 2 is provided with an avoidance notch 25 opposite to the fixing hole 114. The fastener 4 sequentially passes through the inner hole of the fixing post 32, the avoidance notch 25 of the power-taking board 2 and is connected to the fixing hole 114 of the housing 11. Further, the fixing hole 114 is a threaded hole, and the fastener 4 is a screw, which is screwed into the fixing hole 114.

[0095] Such as Figure 10 , Figure 11 and Figure 12As shown, the switch body 1 further includes a circuit board 14, and the circuit board 14 includes a main board body 141 and a connecting board 142. Among them, the main board body 141 is installed in the housing 11; the connecting board 142 extends out of the housing 11 and is electrically connected to the power-taking board 2, so that the electrical signal collected by the power-taking board 2 from the wiring terminal 12 is further transmitted to the circuit board 14 of the switch body 1, enabling the circuit board 14 to obtain the electrical signal and facilitating the intelligent control of the switching device.

[0096] By providing the connecting board 142 that extends out of the housing 11, the electrical connection between the circuit board 14 and the power-taking board 2 can be achieved by operation outside the housing 11, without the need to additionally provide wires or connectors to connect the power-taking board 2 and the circuit board 14 inside the housing 11, which is more convenient to operate and assemble.

[0097] See Figure 5 , a second through-hole 112 is provided on the housing 11 of the switch body 1, and the connecting board 142 extends out of the housing 11 through the second through-hole 112 to be electrically connected to the power-taking board 2.

[0098] In some embodiments, a card slot 22 is provided on the power-taking board 2, and the connecting board 142 penetrates through the card slot 22. A first solder pad 23 is provided on the edge area of the card slot 22 on the power-taking board 2, and a second solder pad 1420 corresponding to the first solder pad 23 is provided on the connecting board 142. The second solder pad 1420 is welded to the first solder pad 23 to achieve the electrical connection between the circuit board 14 and the power-taking board 2. The connecting board 142 is clamped in the card slot 22 of the power-taking board 2, which can improve the connection stability between the connecting board 142 and the power-taking board 2, and at the same time make the layout of the connecting board 142 and the power-taking board 2 more compact. In addition, the distance between the connecting board 142 penetrating through the card slot 22 and the power-taking board 2 is closer. The first solder pad 23 and the second solder pad 1420 are respectively provided on the surfaces of the two close to each other, and then they can be electrically connected together through the soldering process to achieve signal transmission between them. Moreover, the second solder pads 1420 can be arranged on both side surfaces of the connecting board 142 in the thickness direction. Similarly, the first solder pads 23 can be arranged on the edge areas on the opposite sides of the card slot 22, so that the layout space of the first solder pads 23 and the second solder pads 1420 is larger.

[0099] See Figure 11 , the connecting board 142 has an electrical connection board surface 1421 facing the first solder pad 23, and the second solder pad 1420 is provided on the electrical connection board surface 1421. That is, the side surface of the connecting board 142 in the thickness direction is the electrical connection board surface 1421, which is the surface close to the power-taking board 2. The electrical connection board surface 1421 is in contact with the power-taking board 2 or the gap between it and the power-taking board 2 is less than the gap threshold, which is convenient for welding the first solder pad 23 and the second solder pad 1420 together, and at the same time improves the welding quality and firmness after welding between the first solder pad 23 and the second solder pad 1420, thereby improving the signal transmission ability at the welding point.

[0100] Specifically, referring to Figure 11 , the electrical connection board surface 1421 abuts against the groove wall of the card slot 22, or the gap between the electrical connection board surface 1421 and the groove wall of the card slot 22 is less than the gap threshold value. The value of the gap threshold is exemplarily greater than 0 mm and less than 0.5 mm.

[0101] In some other embodiments, the connection board 142 can also be located on one side of the power-taking board 2. For example, referring to the orientation in Figure 12 , the connection board 142 is located on the left side or right side or upper side or lower side of the power-taking board 2. At this time, the side surface of the connection board 142 close to the power-taking board 2 is the electrical connection board surface 1421, on which a second pad 1420 is provided, and a first pad 23 is provided in the area of the power-taking board 2 opposite to the connection board 142. The first pad 23 and the second pad 1420 are welded together, and the signal transmission between the circuit board 14 and the power-taking board 2 can also be realized. In this embodiment, the electrical connection board surface 1421 of the connection board 142 can also abut against the power-taking board 2 or the gap between the connection board 142 and the power-taking board 2 is less than the gap threshold value.
