Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of junction boxes, and more particularly to a component for controlling the continuity of circuits in junction boxes. Background Technology
[0002] A junction box is a product that uses wire harnesses as a transfer connection, making troubleshooting easier and allowing for more flexible operation during fault injection testing without damaging intact wire harnesses. Most current junction boxes use a standard banana plug with a T-connector to control continuity. Current assembly methods involve many parts, are cumbersome, and the T-connector protrudes unsightly, resulting in high overall material costs.
[0003] Therefore, in order to address the shortcomings of the above-mentioned problems, a component for controlling the continuity of circuits in a junction box is proposed. Summary of the Invention
[0004] This invention overcomes the shortcomings of the prior art and provides a component for controlling the continuity of circuits in a junction box.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a component for controlling the continuity of a junction box circuit, comprising: a double socket and a shorting pin;
[0006] The double socket includes: two housings, two U-shaped contact pieces disposed between the two housings, and a spring expansion sleeve disposed between the two U-shaped contact pieces;
[0007] The two U-shaped contacts are located between the two housings, the two spring expansion sleeves are located between the two U-shaped contacts, and the shorting pin is plugged into the double socket.
[0008] In a preferred embodiment of this utility model, the two outer shells are ultrasonically welded together, and both sides of the two U-shaped contact pieces are rounded. Ultrasonic welding technology can ensure a tight connection between the two outer shells without gaps, thereby improving the structural strength and stability of the entire component. The rounded shape of the U-shaped contact pieces is not only aesthetically pleasing, but also increases the contact area with the shorting pin, ensuring a more stable electrical connection.
[0009] In a preferred embodiment of this utility model, each of the two U-shaped contacts extends a welding pin at one end. The welding pin enables the U-shaped contacts to be welded to the circuit, thereby realizing the connection of the circuit. The welding method is more stable than the plugging and unplugging method, and is not easy to loosen, which can ensure the long-term stable operation of the circuit.
[0010] In a preferred embodiment of this utility model, an open cylinder is formed between the two U-shaped contacts. The U-shaped contacts and the spring expansion sleeve are both made of conductive metal to ensure smooth current transmission and reduce resistance and heat loss. The spring expansion sleeve provides a certain degree of elasticity between the U-shaped contacts, which can adapt to shorting pins of different sizes and ensure tight contact.
[0011] In a preferred embodiment of this utility model, the U-shaped contact piece is covered with spring expansion sleeves on both sides by arcs. The spring expansion sleeves can fix the position of the U-shaped contact piece and prevent it from moving or deforming during use. The elasticity of the spring expansion sleeves can ensure tight contact between the U-shaped contact piece and the shorting pin, reduce contact resistance, improve electrical performance, and absorb and buffer vibration, protecting the connection between the U-shaped contact piece and the shorting pin from vibration.
[0012] In a preferred embodiment of this utility model, the outer circumferential wall of the shorting pin is provided with a drum spring. The drum spring can increase the contact area between the shorting pin and the U-shaped contact piece, thereby improving the stability and reliability of the electrical connection. The elasticity of the drum spring can adapt to U-shaped contact pieces of different sizes, so that the shorting pin can be widely used in different types of junction boxes, and can reduce the resistance during the insertion and removal process, so that the shorting pin can be easily inserted into and removed from the double socket.
[0013] In a preferred embodiment of this utility model, the drum spring is made of conductive material, which can ensure the electrical connection between the short-circuit pin and the U-shaped contact piece, thereby realizing the on / off control of the circuit. The conductive material drum spring has low resistance and high conductivity, which can ensure smooth current transmission.
[0014] In a preferred embodiment of this utility model, the shorting pin is located in the middle of the double socket, and the outer circumferential wall of the shorting pin contacts two U-shaped contact pieces. The shorting pin can be replaced by a conventional banana plug. The shorting pin being located in the middle of the double socket ensures that it contacts both U-shaped contact pieces simultaneously, thereby realizing the on / off control of the circuit. Furthermore, the shorting pin can be replaced by a conventional banana plug, increasing the compatibility and flexibility of the product, allowing users to easily connect and disconnect the circuit.
[0015] In a preferred embodiment of this utility model, elastic buckles are provided on both sides of the double socket.
[0016] In a preferred embodiment of this utility model, after the shorting pin is inserted into the double socket, the upper surface of the shorting pin is flush with the upper surface of the double socket, which can ensure the flat appearance of the product.
[0017] This utility model solves the defects existing in the background technology, and has the following beneficial effects:
[0018] (1) This utility model provides a component for controlling the continuity of a circuit in a disconnect box. By setting up a double socket and a shorting pin, the drum spring on the shorting pin is made of conductive material. When the shorting pin is inserted into the double socket, the drum spring contacts the cylindrical cavity wall formed by the U-shaped contact piece, thereby realizing the conduction of the soldered pins on both sides of the double socket. Conversely, when the shorting pin is pulled out of the double socket, the conduction of the soldered pins on both sides is broken, making the entire device body easy to mass-produce. This not only significantly reduces the height of the product, but also reduces the weight, and further reduces the material cost of the device body.
[0019] (2) This utility model provides a component for controlling the continuity of the circuit in the disconnect box. After the shorting pin is inserted into the double socket, the shorting pin is flush with the upper edge of the double socket, ensuring the product has a flat appearance. In addition, the shorting pin can be replaced by a conventional banana plug, increasing the compatibility and flexibility of the product. Attached Figure Description
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments;
[0021] Figure 1 This is a first-view structural diagram of the device body of a preferred embodiment of the present invention;
[0022] Figure 2 This is a second-view structural diagram of the device body according to a preferred embodiment of the present invention.
[0023] In the diagram: 1. Double socket; 2. Shorting pin; 3. Housing; 4. Spring expansion sleeve; 5. U-shaped contact piece. Detailed Implementation
[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0025] like Figure 1 As shown, an assembly for controlling the continuity of a junction box includes: a double socket 1 and a shorting pin 2.
[0026] like Figure 2 As shown, the double socket 1 includes: two housings 3, two U-shaped contact pieces 5 disposed between the two housings 3, and a spring expansion sleeve 4 disposed between the two U-shaped contact pieces 5;
[0027] Two U-shaped contact pieces 5 are located between two outer shells 3, two spring expansion sleeves 4 are located between two U-shaped contact pieces 5, and the short-circuit pin 2 is plugged into the double socket 1;
[0028] The two outer shells 3 are ultrasonically welded together. Both sides of the two U-shaped contact pieces 5 are rounded. One end of each of the two U-shaped contact pieces 5 extends out as a welding pin. An open cylinder is formed between the two U-shaped contact pieces 5. The U-shaped contact pieces 5 and the spring expansion sleeve 4 are both made of conductive metal. The rounded sides of the U-shaped contact pieces 5 cover the spring expansion sleeve 4.
[0029] The outer circumference of the shorting pin 2 is provided with a drum spring, which is made of conductive material. The shorting pin 2 is located in the middle of the double socket 1, and the outer circumference of the shorting pin 2 is in contact with two U-shaped contact pieces 5.
[0030] It should be noted that the insertion of the shorting pin 2 into the double socket 1 allows users to easily switch the circuit on and off, greatly simplifying the operation process and improving ease of use. The arc design of the U-shaped contact piece 5 and the elasticity of the spring expansion sleeve 4 together ensure a tight and stable contact, effectively reducing circuit faults and enhancing connection reliability. Furthermore, the device itself is simple and easy to mass-produce and assemble, reducing material and production costs while improving production efficiency. The compatibility design of the shorting pin 2 allows it to be replaced with a conventional banana plug, further increasing flexibility. The outer shell 3 of the double socket 1 is fixed by ultrasonic welding, ensuring a smooth and aesthetically pleasing appearance.
[0031] like Figures 1-2 As shown, both sides of the double socket are equipped with elastic buckles. After the shorting pin is inserted into the double socket, the upper surface of the shorting pin is flush with the upper surface of the double socket, which can ensure the flat appearance of the product.
[0032] It should be noted that after the shorting pin 2 is inserted, it is flush with the upper surface of the double socket 1, which improves the overall aesthetics of the product.
[0033] In use, the outer shell 3 serves to limit the spring expansion sleeve 4 and the U-shaped contact piece 5, and is placed symmetrically on the left and right. The two outer shells 3 are formed into one piece by ultrasonic welding technology, which firmly fixes the spring expansion sleeve 4 and the U-shaped contact piece 5, thus forming a complete double socket 1 component. One end of the U-shaped contact piece 5 extends a welding pin for connecting to the wire harnesses at both ends.
[0034] When the shorting pin 2 is plugged into the double socket 1, the drum spring on the shorting pin 2 makes tight contact with the cylindrical cavity wall formed by the U-shaped contact piece 5, thereby achieving conductivity between the soldered pins on both sides of the double socket 1. At this time, the wire harness connected through the double socket 1 will also be conductive, realizing the connection of the circuit.
[0035] Conversely, when it is necessary to disconnect the circuit, simply pull the shorting pin 2 out of the double socket 1. After pulling it out, the contact between the drum spring on the shorting pin 2 and the U-shaped contact piece 5 is broken, and the soldered pins on both sides of the double socket 1 are also disconnected, thus achieving the disconnection of the circuit.
[0036] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
