Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a foolproof terminal socket. Background Technology

[0002] Terminal sockets are core basic components in the field of electrical connections. As a key interface for achieving safe and efficient power and signal transmission, they provide stable and reliable pluggable connection solutions for various wires through a precisely designed metal conductor and insulating shell structure. They are widely used in industrial control cabinets, home appliances, communication equipment and power systems, etc. They are characterized by convenient installation, simple maintenance, various protection levels and the ability to withstand high current and voltage. They are an indispensable and important part of modern electrical wiring to ensure circuit continuity, modular organization and improve safety.

[0003] Traditional screw-driven pressure plate terminal sockets have two approximately symmetrical cavities within the socket due to the pressure plate separating the wires. This makes it easy for operators to mistakenly insert wires into the unsecured cavity due to visual errors or operational habits, leading to serious hazards such as loose connections, false connections, or even power failure. Therefore, an effective foolproof design is introduced. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foolproof terminal socket, including a base body and a clamping assembly, wherein the clamping assembly includes a pressure plate slidably installed inside the base body, a baffle fixedly connected to one side of the pressure plate, and a single cavity formed between the base body and the baffle and the pressure plate, the cavity being a clamping cavity for placing cables.

[0006] In at least some embodiments, the seat is provided in multiple ways, each seat has a groove on one side and a slide plate on the other side, the slide plate of an adjacent seat is inserted into the groove of another seat, and the combination is achieved by friction.

[0007] In at least some embodiments, the clamping also includes a screw, and a through hole is provided on one side of the base body, with the screw being rotatably mounted at the through hole position of the base body.

[0008] In at least some embodiments, a mouth-shaped plate is slidably installed inside the base body. The mouth-shaped plate is slidably installed inside the slot of the base body, and a mouth-shaped cavity is opened inside the mouth-shaped plate. The pressure plate cooperates with the mouth-shaped cavity of the mouth-shaped plate to form the clamping cavity.

[0009] In at least some embodiments, one side of the mouth-shaped plate is screwed to the screw, and one side of the mouth-shaped plate is fixedly connected to an insert plate. The insert plate is used to weld onto the control board. In use, rotating the screw drives the mouth-shaped plate to move laterally relative to the seat. At this time, the seat moves towards the control board, changing the size of the clamping cavity, thereby realizing the clamping action of the wire and the fitting and fixing action of the seat and the control board.

[0010] In at least some embodiments, a limiting plate is fixedly connected to one side of the baffle, and the screw passes through the limiting hole of the limiting plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, when the operator inserts the cable into the specially designed clamping cavity on the base, the integrated design of the baffle and pressure plate, along with their precise fit with the base structure, ensures that the entire socket is no longer divided but forms a single, clearly oriented cavity. This fundamentally eliminates the possibility of accidentally inserting the cable into other invalid cavities. The clamping assembly applies uniform and vertically downward pressure to the cable placed in the single clamping cavity from top to bottom, and achieves stable and reliable clamping contact through the cooperation between the bottom of the pressure plate and the bottom platform of the base. The entire process does not require the operator to identify the cavity, achieving a foolproof effect of "only one hole, guaranteed to be pressed correctly," greatly improving the accuracy and safety of wiring.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Implementation examples, based on Figures 1-4 As shown in the figure, the present invention provides a foolproof terminal socket, including a base 1 and a clamping assembly 3. The clamping assembly 3 includes a pressure plate 306 slidably installed inside the base 1. A baffle 304 is fixedly connected to one side of the pressure plate 306. A single cavity is formed between the base 1 and the baffle 304 and the pressure plate 306. The cavity is a clamping cavity 7, which is used to place cables.

[0017] The aforementioned foolproof terminal socket, when the operator inserts the cable into the specially designed clamping cavity 7 on the base 1, due to the integrated design of the baffle 304 and the pressure plate 306 and their precise fit with the structure of the base 1, the entire socket is no longer divided but forms a unique, clearly oriented single cavity, thereby fundamentally eliminating the possibility of accidentally entering other invalid cavities from a physical structure perspective. Subsequently, when driven by rotating the screwdriver, the clamping assembly 3 will apply uniform and vertically downward pressure to the cable placed in the single clamping cavity 7 from top to bottom, and achieve stable and reliable clamping contact through the cooperation between the bottom of the pressure plate 306 and the bottom platform of the base 1. The entire process does not require the operator to identify the cavity, and achieves the foolproof effect of "only one hole, must be pressed into the correct position".

[0018] In this embodiment, there are multiple seat bodies 1. Each seat body 1 has a groove 4 on one side and a slide plate 5 on the other side. The slide plate 5 of an adjacent seat body 1 is inserted into the groove 4 of another seat body 1, and the combination is achieved by friction.

[0019] Adjacent bases 1 are combined by the insertion and engagement of their unique sliding plates 5 and sliding grooves 4 on their side walls. During installation, simply push the sliding plate 5 of one base 1 into the sliding groove 4 of another base 1. With the precision-designed interference fit generating sufficient frictional resistance, multiple bases 1 can be quickly and stably assembled without tools to form a neat modular terminal block.

[0020] In this embodiment, the clamping mechanism also includes a screw 301. A through hole 2 is provided on one side of the base 1, and the screw 301 is rotatably installed at the through hole 2 position of the base 1. A mouth-shaped plate 302 is also slidably installed inside the base 1. The mouth-shaped plate 302 is slidably installed inside the slot 6 of the base 1, and a mouth-shaped cavity 307 is provided inside the mouth-shaped plate 302. A pressure plate 306 cooperates with the mouth-shaped cavity 307 of the mouth-shaped plate 302 to form a clamping cavity 7. One side of the mouth-shaped plate 302 is screwed to the screw 301, and... A plug plate 303 is fixedly connected to one side of the mouth-shaped plate 302. The plug plate 303 is used to weld onto the control plate. When in use, rotating the screw 301 drives the mouth-shaped plate 302 to move laterally relative to the seat 1. At this time, the seat 1 moves towards the control plate, changing the size of the clamping cavity 7, thereby realizing the clamping action of the wire and the contact and fixing action of the seat 1 with the control plate. A limit plate 305 is fixedly connected to one side of the baffle 304, and the screw 301 passes through the limit hole of the limit plate 305.

[0021] The core of the clamping function of this foolproof terminal socket is achieved by the precise linkage of the screw 301, the orifice plate 302 and the pressure plate 306 assembly. When it is necessary to clamp the wire, the operator uses a tool to rotate the screw 301 installed in the through hole 2 on one side of the base 1. Since the screw 301 and the orifice plate 302 are threadedly engaged on one side, and the orifice plate 302 is slidably locked in the slot 6 in the base 1 through its two side structures and is constrained by the limiting hole on the limiting plate 305, its rotational freedom can only move horizontally. Therefore, the rotational motion of the screw 301 is converted into the lateral linear motion of the orifice plate 302. At this time, the baffle 304 fixedly connected to one side of the pressure plate 306 and the limiting plate 305 connected thereto jointly ensure that the pressure plate 306 assembly will not rotate with the screw 301 and can only move vertically. When the orifice plate 302 is driven by the screw 301 to move laterally in the direction of the principle control plate, the relative position between the orifice cavity 307 opened inside it and the fixed pressure plate 306 changes, resulting in a reduction in the volume of the only clamping cavity 7 formed by the two, thereby evenly clamping the wire placed in the cavity from all sides to achieve reliable clamping. Meanwhile, since one side of the orifice plate 302 has been welded and fixed to the control board via the insert plate 303, when the orifice plate 302 is driven by the screw 301 and cannot move on its own, the reaction force will drive the entire seat 1 to move smoothly along the surface of the orifice plate 302 toward the control board until the bottom of the seat 1 is tightly attached to the surface of the control board. Finally, the secure clamping of the wire and the installation and fixing of the terminal socket body on the control board are completed simultaneously. The whole process achieves two effects through mechanical linkage: it not only solves the problem of misinsertion caused by the traditional pressure plate 306 cavity division, but also simplifies the installation steps and greatly improves efficiency and reliability.

[0022] The working principle of this utility model is as follows: When the operator inserts the cable into the specially designed clamping cavity 7 on the base 1, due to the integrated design of the baffle 304 and the pressure plate 306 and their precise cooperation with the structure of the base 1, the entire inside of the socket is no longer divided but forms a unique, clearly oriented single cavity, thus fundamentally eliminating the possibility of accidentally entering other invalid cavities from a physical structure perspective; subsequently, when driven by rotating the screwdriver, the clamping component 3 will apply uniform and vertically downward pressure to the cable placed in the unique clamping cavity 7 from top to bottom, and achieve stable and reliable clamping contact through the cooperation between the bottom of the pressure plate 306 and the bottom platform of the base 1. The entire process does not require the operator to identify the cavity, achieving the foolproof effect of "only one hole, must be pressed into the correct position".

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
