Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a high-temperature resistant single-core connector. Background Technology

[0002] Thermal batteries, as a type of energy source with high specific power and specific energy, have a wide range of important applications, and the products require high levels of processability and reliability. Among these, the connection between the battery cover terminals and the wires is particularly important, serving as the channel for battery activation and energy output. Because it is close to the battery body, the connection point must withstand high temperatures after battery activation. A common process involves directly soldering the wires to the terminals and then applying adhesive, which is not only complex in operation and process, but also makes the solder joints and adhesive highly susceptible to melting and aging at high temperatures, leading to overall battery failure. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a high-temperature resistant single-core connector. It uses a connector to replace the original connection process, and adopts a threaded locking structure for more convenient and reliable connection. In terms of electrical structure, it uses a flexible socket combined with a rigid pole and a fastening ring to ensure reliable contact in high-temperature environments. It balances structural reliability, electrical contact reliability and high-temperature operation reliability in a very small space.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This utility model provides a high-temperature resistant single-core connector, including a pole and a single-core connector plug. The single-core connector plug includes a fastening ring, a resilient socket, a gasket, and a housing. The gasket and the resilient socket are sequentially installed into the housing. The fastening ring is connected to the pole. The pole is inserted into the resilient socket and connected to the housing by a thread.

[0006] Furthermore, the pole post includes a cylindrical structure and a thickened cylindrical structure, one end of the cylindrical structure is hemispherical, and the thickened cylindrical structure is provided with threads;

[0007] Furthermore, both ends of the outer casing are open, one end has a thread on its inner side, which engages with the thread on the thickened cylindrical structure to connect the pole post and the outer casing, and the other end is open to expose one end of the elastic insertion hole, and the outer side of the outer casing has a mesh pattern.

[0008] Furthermore, the fastener is made of copper alloy, the fastener has a ring structure, and the inner side of the fastener is provided with a fastener bevel.

[0009] Furthermore, the flexible socket is made of copper alloy, and the outer side of one end of the flexible socket inserted into the pole is provided with a socket bevel, which cooperates with the bevel of the fastener to ensure the single-core connector plug is in contact with the pole when the pole and the single-core connector plug are locked. The other end of the flexible socket is connected to an external wire.

[0010] Furthermore, the gasket is made of polytetrafluoroethylene, and the outer shell and the pole are made of an expanded alloy.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model of a high-temperature resistant single-core connector reduces the cumbersome process of soldering wires to the terminals and applying adhesive. During connector manufacturing, the wires are directly soldered or crimped to the root of the flexible socket. When connection is needed, the outer shell is simply locked to the terminal via threads to achieve a reliable connection. Furthermore, the compact structure of the single-core connector meets the requirements of use in confined spaces. On the other hand, it significantly improves maintainability and reliability. When repair or replacement is required, simply unscrewing the threads separates the terminal and the single-core connector plug, eliminating the tedious adhesive removal and desoldering processes. Simultaneously, because the wires are now connected to the root of the flexible socket instead of the terminal, they are less affected by battery heat, resulting in greater reliability.

[0013] 2. This utility model ensures the reliability of electrical connections at high temperatures through the ingenious internal design of the single-core connector. A retaining ring is added between the pole and the flexible socket. This simplifies the structure, eliminating the need for complex designs and manufacturing processes. Furthermore, the inclined limiting structure firmly fixes the flexible socket to the pole, ensuring reliable contact even if the socket loses its elasticity at high temperatures. Since the coefficient of thermal expansion of the copper alloy used for the flexible socket and retaining ring is greater than that of the expansion alloy used for the pole and shell, the limiting effect strengthens at higher temperatures, guaranteeing reliable electrical connections even at temperatures exceeding 300°C. Additionally, a PTFE gasket is placed at the contact point between the flexible socket and the shell, making rotation and connection easier and smoother. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1-3 One embodiment of this utility model is a high-temperature resistant single-core connector, including a pole 1 and a single-core connector plug 2. The single-core connector plug 2 includes a fastening ring 21, a flexible socket 22, a gasket 23, and a housing 24. The gasket 23 and the flexible socket 22 are sequentially installed into the housing 24. The fastening ring 21 is connected to the pole 1. The pole 1 is inserted into the flexible socket 22 and is connected to the housing 24 by a thread.

[0021] The electrode post 1 includes a cylindrical structure 11 and a thickened cylindrical structure 12. The electrode post 1 is machined from an expanded alloy. One end of the cylindrical structure 11 is hemispherical to facilitate the placement and insertion of the fastening ring 21 into the elastic insertion hole 22. The thickened cylindrical structure 12 is provided with threads. The electrode post 1 is changed from a solid cylindrical structure to a partially thickened structure, and threads are machined at the thickened position. In addition to connecting and locking with the outer shell 24, the thickened cylindrical structure 12 also provides a limiting function for the fastening ring 21. The other end of the cylindrical structure 11 is sintered with the battery cover glass.

[0022] The outer shell 24 is machined from an expanded alloy to provide overall structural support. Both ends of the outer shell 24 are open. One end has a thread on its inner side, which engages with the thread on the thickened cylindrical structure 12 to connect and lock the pole post 1 and the outer shell 24. The other end is open so that one end of the elastic insertion hole 22 is exposed and connected to the external wire. The outer side of the outer shell 24 has a textured surface to provide friction for easy manual tightening.

[0023] The fastener 21 is machined from copper alloy and has a ring structure. The inner side of the fastener 21 is provided with a fastener bevel 211.

[0024] The flexible socket 22 is machined from copper alloy. The outer side of the end of the flexible socket 22 that is inserted into the pole 1 is provided with a beveled surface 221, which cooperates with the beveled surface 211 of the fastener. When the pole 1 and the single-core connector plug 2 are locked, the single-core connector plug 2 is ensured to fit with the pole 1, and the end of the flexible socket 22 is firmly fitted with the pole 1. The other end of the flexible socket 22 is connected to an external wire. In the high-temperature environment after the thermal battery is activated, the fit will be tighter because the coefficient of thermal expansion of the copper alloy used in the flexible socket 22 and the fastening ring 21 is greater than that of the expansion alloy used in the pole 1 and the outer shell 24.

[0025] The gasket 23 is machined from polytetrafluoroethylene, and the material’s self-lubricating properties make the thread insertion process smooth and without jamming.

[0026] Working principle: During assembly, the gasket 23 and the flexible socket 22 are inserted into the outer casing 24 in sequence, with the tail of the flexible socket 22 protruding to connect to the rear lead wire. Because the terminal 1 is connected to the thermal battery by glass sintering, the user only needs to place the fastening ring 21 on the terminal 1 first, and then insert the assembly of the flexible socket 22 with the lead wire connected, the gasket 23 and the outer casing 24 into the terminal 1 and tighten it.

[0027] This invention, employing a high-temperature resistant single-core connector, reduces the cumbersome process of soldering wires to the terminals and applying adhesive. During connector manufacturing, the wires are directly soldered or crimped to the base of the elastic socket 22. When connection is needed, the outer shell 24 is simply locked to the terminal 1 via threads, achieving a reliable structural connection. Furthermore, the compact single-core connector design meets the requirements of use in confined spaces. On the other hand, it significantly improves maintainability and reliability. When repair or replacement is required, simply unscrewing the threads separates the terminal 1 from the single-core connector plug 2, eliminating the need for tedious adhesive removal and desoldering processes. Simultaneously, because the wire connection changes from being to the terminal to being to the base of the elastic socket 22, it is less affected by battery heat, resulting in greater reliability.

[0028] This invention, through ingenious internal design of the single-core connector, ensures the reliability of the electrical connection at high temperatures. A fastening ring 21 is added between the pole 1 and the flexible socket 22. This simplifies the structure, eliminating the need for complex designs and manufacturing processes. Furthermore, the inclined limiting structure firmly secures the flexible socket 22 to the pole 1. Even if the flexible socket 22 loses its elasticity at high temperatures, it still maintains reliable contact with the pole 1. Moreover, because the coefficient of thermal expansion of the copper alloy used for the flexible socket 22 and the fastening ring 21 is greater than that of the expansion alloy used for the pole 1 and the outer shell 24, the limiting effect strengthens at higher temperatures, ensuring reliable electrical connection even at temperatures exceeding 300°C. Additionally, a polytetrafluoroethylene gasket 23 is provided at the contact point between the flexible socket 22 and the outer shell 24, making rotational docking easier and smoother. Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
