Description

Technical Field

[0001] This invention relates to the field of electrical technology, and more particularly to a spring contact structure. Background Technology

[0002] With increasingly stringent requirements for the stability of electrical products, spring-loaded terminal blocks are becoming more and more widely used. Traditional spring-loaded terminal blocks consist of a spring and a metal conductor. One end of the spring is fixedly connected to the metal conductor, and the other end abuts against the metal conductor. When wiring, the wire is inserted between the end of the spring that abuts against the metal conductor and the metal conductor. The spring presses the wire in place, ensuring a stable connection between the wire and the metal conductor.

[0003] In the existing technology, when disassembling the wire, a screwdriver is usually used to hold the spring clip, and the hand keeps applying force to the screwdriver to deform the spring clip and detach it from the wire. This is the only way to pull the wire out from between the spring clip and the metal conductor, which is not convenient for disassembling the wire. Summary of the Invention

[0004] The purpose of this invention is to provide a spring contact structure that improves the ease of disassembling wires.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The spring contact structure includes:

[0007] The base is symmetrically equipped with two first sockets and two second sockets;

[0008] Two conductors are symmetrically arranged on the base;

[0009] A contact base, two of which are symmetrically arranged on the base, each contact base including a first fulcrum;

[0010] Two springs are symmetrically arranged on the base. One end of each spring is located on the base, and the other end of each spring selectively fits onto the contact seat and can cover the first and second sockets. A second fulcrum and a third fulcrum are provided on the spring at intervals.

[0011] A wire is selectively inserted into the first socket, and the sidewall of the wire abuts against the conductor. When the wire is configured to be inserted into the first socket, the wire pushes the other end of the spring away from the contact seat, and the other end of the spring abuts against the wire.

[0012] Optionally, one end of the spring is hook-shaped, and one end of the spring is wound around a protruding post on the base.

[0013] Optionally, the other end of the spring sheet is provided with a first bend and a second bend that are connected to each other, the second fulcrum is located at the first bend, and the third fulcrum is located at the second bend.

[0014] Optionally, the base includes a base plate and a side plate fixed to the periphery of the base plate. The side plate and the base plate together form a receiving cavity. The conductor and the spring are both located in the receiving cavity. The first socket and the second socket are both located on the side plate.

[0015] Optionally, the contact seat includes a top plate, one end of which is connected to the side plate, and the top plate extends in a direction parallel to the bottom plate. The first fulcrum is located on the top plate and protrudes in the direction of the spring sheet.

[0016] Optionally, the spring contact structure further includes a cover plate, which covers the opening of the receiving cavity.

[0017] Optionally, the contact base further includes a guide plate connected to the edge of the top plate, and the guide plate has a through hole on the side away from the side plate, and the through hole is directly opposite to the first socket.

[0018] The outer side of the guide plate and the side plate form an inlet channel, and the inlet channel is correspondingly provided with the second socket.

[0019] Optionally, the conductive surface of the conductor is configured as an inclined plane.

[0020] Optionally, the other end of the spring sheet is provided with an elongated dividing hole, which extends along the length of the spring sheet.

[0021] Optionally, the conductor is made of copper.

[0022] The beneficial effects of this invention are as follows: In the spring contact structure provided by this invention, when the wire is not inserted into the first socket, the other end of the spring contacts adheres to the contact base and covers the first socket. When the wire is inserted into the first socket, the wire pushes that end of the spring contacts away from the contact base, and that end of the spring contacts presses against the wire, so that the wire abuts against the conductor. The elastic force of the spring contacts locks the wire and the conductor in a locked state. By providing a first fulcrum on the contact base and a second and third fulcrum at intervals on the spring contacts, the line connecting the first, second, and third fulcrums forms a triangle. When it is necessary to remove the wire, a screwdriver is used. Insert the screwdriver into the second connector. The end of the screwdriver pushes the other end of the spring away from the wire. One side of the screwdriver shank abuts against the first fulcrum, and the other side abuts against the second and third fulcrums, which are spaced apart. With the first fulcrum as the fulcrum, the clamping force of the second and third fulcrums on the screwdriver is greater than the weight of the screwdriver, keeping the screwdriver stable and preventing it from slipping out of the second connector. This keeps the other end of the spring detached from the wire. At this point, the wire can be removed with one hand, while the other hand does not need to keep pressing the screwdriver, improving the efficiency and convenience of wire removal.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0041] This embodiment provides a spring contact structure, which includes a spring contact body and a wire. The wire is selectively inserted into the spring contact body. This spring contact structure facilitates the removal of the wire from the spring contact body, improving the ease of wire disassembly.

[0042] Specifically, such as Figures 1-6 As shown, the spring contact body includes a base 100, a conductor 200, a contact seat 300, and a spring 400. The base 100 is symmetrically provided with two first sockets 121 and two second sockets 122; two conductors 200 are symmetrically arranged on the base 100; two contact seats 300 are symmetrically arranged on the base 100, and each contact seat 300 includes a first fulcrum 311; two springs 400 are symmetrically arranged on the base 100, with one end of the spring 400 attached to the base 100 and the other end attached to the base 100. The spring 400 is selectively attached to the contact base 300 and can cover the first socket 121 and the second socket 122. The spring 400 is provided with a second fulcrum 411 and a third fulcrum 421 at intervals. The wire 500 is selectively inserted into the first socket 121, and the side wall of the wire 500 abuts against the conductor 200. When the wire 500 is configured to be inserted into the first socket 121, the wire 500 pushes the other end of the spring 400 away from the contact base 300, and the other end of the spring 400 abuts against the wire 500.

[0043] The spring contact structure provided by this invention allows for the following configuration: when the wire 500 is not inserted into the first socket 121, the other end of the spring 400 is attached to the contact base 300 and covers the first socket 121. When the wire 500 is inserted into the first socket 121, the wire 500 pushes the end of the spring 400 away from the contact base 300, and the end of the spring 400 presses against the wire 500, so that the wire 500 abuts against the conductor 200. A first fulcrum 311 is provided on the contact base 300, and a second fulcrum 411 and a third fulcrum 421 are spaced apart on the spring 400. The line connecting the first fulcrum 311, the second fulcrum 411, and the third fulcrum 421 forms a triangle. When it is necessary to remove the wire 500, a screwdriver 100' is inserted into the second socket 122. The end of the screwdriver 100' pushes the other end of the spring 400 away from the wire 500. One side of the screwdriver 100's shaft abuts against the first fulcrum 311, and the other side of the shaft abuts against the second fulcrum 411 and the third fulcrum 421, which are spaced apart. The first fulcrum 311 is the fulcrum, and the clamping force of the second fulcrum 411 and the third fulcrum 421 on the screwdriver 100' is greater than the weight of the screwdriver 100', so that the screwdriver 100' remains stationary and prevents the screwdriver 100' from sliding out of the second socket 122. This keeps the other end of the spring 400 detached from the wire 500. At this time, the wire 500 can be removed with one hand, while the other hand does not need to keep pressing the screwdriver 100', which improves the efficiency and convenience of wire removal.

[0044] Optionally, the base 100 includes a base plate 110 and a side plate 120 fixed to the periphery of the base plate 110. The side plate 120 and the base plate 110 together form a receiving cavity. The conductor 200 and the spring piece 400 are both located within the receiving cavity. The first socket 121 and the second socket 122 are both provided on the side plate 120. The conductor 200 and the spring piece 400 are disposed within the receiving cavity to protect the conductor 200 and the spring piece 400 from external damage.

[0045] Furthermore, the contact base 300 includes a top plate 310, one end of which is connected to the side plate 120, and the top plate 310 extends in a direction parallel to the bottom plate 110. A first fulcrum 311 is provided on the top plate 310 and protrudes in the direction toward the spring piece 400, so that the contact base 300 and the spring piece 400 can fit better when the wire 500 is not inserted into the first socket 121.

[0046] In this embodiment, the spring contact structure also includes a cover plate, which covers the opening of the receiving cavity to protect the conductor 200 and the spring 400.

[0047] Furthermore, the contact base 300 also includes a guide plate 320 connected to the edge of the top plate 310. The guide plate 320 has a through hole on the side away from the side plate 120, which is directly opposite to the first socket 121. The outer surface of the guide plate 320 and the side plate 120 form an inlet channel, which is correspondingly arranged with the second socket 122. The insertion end of the wire 500 passes through the first socket 121 and the through hole in sequence. The through hole can further limit the wire 500 and prevent it from shaking. When it is necessary to remove the wire 500, the end of the screwdriver 100' is inserted into the second socket 122 and enters the inlet channel. The inlet channel plays a guiding role, ensuring that the screwdriver 100' can quickly enter the receiving cavity, thereby improving the disassembly efficiency.

[0048] Optionally, one end of the spring 400 is hook-shaped, and one end of the spring 400 is wound around the protruding post on the base 100 to improve the fixing reliability of the spring 400.

[0049] Furthermore, the other end of the spring 400 is provided with a first bent portion 410 and a second bent portion 420 connected to each other. A second fulcrum 411 is provided at the first bent portion 410 and a third fulcrum 421 is provided at the second bent portion 420. The first bent portion 410 and the second bent portion 420 connected to each other form an S-shaped structure to provide sufficient clamping force to the screwdriver 100'.

[0050] Preferably, the conductor surface of the conductor 200 is set as an inclined surface, and the conductor 500 enters the cavity along the conductor surface, which improves the efficiency of the conductor 500 being inserted into the first socket 121.

[0051] Optionally, the conductor 200 is made of copper, which has high conductivity, flexibility and high adaptability, and good corrosion resistance.

[0052] When two 500mm wires need to be inserted into the contact body of the spring contact, such as Figure 7 As shown, an elongated dividing hole 430 can be provided at the other end of the spring piece 400. The elongated dividing hole 430 extends along the length of the spring piece 400 and divides the other end of the spring piece 400 into two spring strips. When one of the wires 500 needs to be removed, a screwdriver 100' can be used to press against one of the spring strips to move the spring strip away from its corresponding wire 500, and the wire 500 can be removed.

[0053] The usage process of the spring contact structure provided in this embodiment is as follows: The wire 500 is inserted into the first socket 121, pushing the spring 400. The elastic force of the spring 400 locks the wire 500 and the conductor 200 in a locked state. When it is necessary to remove the wire 500, a screwdriver 100' is inserted into the second socket 122. The screwdriver 100' pushes the spring 400 to disengage it from the wire 500, and one side of the screwdriver 100' presses against the first fulcrum 3 on the contact seat 300. 11. The second fulcrum 411 and the third fulcrum 421 on the spring 400 exert a reaction force on the screwdriver 100'. The clamping force of the first fulcrum 311, the second fulcrum 411 and the third fulcrum 421 on the screwdriver 100' is greater than the weight of the screwdriver 100', preventing the screwdriver 100' from slipping out of the second socket 122. At this time, the wire 500 can be taken out without having to manually press the screwdriver 100' all the time, which improves the convenience of disassembling the wire 500.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
