Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a probe-type anti-vibration connector. Background Technology

[0002] Currently, demanding application scenarios, represented by new energy vehicles and industrial equipment, are undergoing rapid development and technological innovation, placing unprecedentedly high demands on the stability and reliability of internal electrical connections. As a core component of electrical connections, traditional probe connectors are widely used due to their simple structure and low cost.

[0003] However, the working principle of the probe-type connector relies on the contact and sliding conductivity between the probe and the shell. In a continuous vibration environment, this contact method that relies on mechanical deformation is prone to fretting wear at the contact interface between the probe and the socket. Therefore, when exposed to vibration for a long time, poor contact between the probe and the shell is likely to occur, which in turn can lead to signal transmission interruption, data loss, or even system malfunction.

[0004] Therefore, in order to meet the durability requirements in galvanometer environments, we propose a probe-type anti-vibration connector. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the easy occurrence of fretting wear at the contact interface between the probe and the socket, resulting in poor contact, and to propose a probe-type anti-vibration connector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a probe-type vibration-damping connector, including: A base and several probe assemblies mounted on the base; The probe assembly includes a housing and a needle rod slidably connected in the housing. A tail plug is fixedly installed at the bottom of the housing, and a conductive element is fixedly installed above the tail plug. The bottom of the needle rod has a mounting hole, and the head end of the conductive element slides in the mounting hole. An elastic sleeve that elastically contacts the conductive element is provided in the mounting hole.

[0007] Furthermore, the top of the outer casing has an inwardly narrowed opening, and the outer side of the needle bar has a stop ring platform that stops on the inner side of the inwardly narrowed opening. A spring is placed between the stop ring platform and the tail plug.

[0008] Furthermore, the conductive element includes a metal rod fixed to the tail plug, and a limiting ball is fixedly installed at the head end of the metal rod.

[0009] Furthermore, the elastic kit includes a base ring fixedly installed in the mounting hole, and a plurality of cantilever arms are fixedly installed on the base ring. The periphery of the plurality of cantilever arms forms a frustum structure, and the plurality of cantilever arms contact the outside of the metal rod.

[0010] Furthermore, the tail plug includes a connecting section and a plug section. The plug section is inserted into the tail end of the housing. A limiting ring is also formed on the outer side of the plug section. The conductive element and the plug section are fixedly connected.

[0011] Furthermore, a plurality of openings are provided on the end face of the base, and the plurality of openings form an elastic cavity inside the base. An anti-fool post is also formed below the base.

[0012] The probe-type anti-vibration connector proposed in this utility model has the following advantages: Based on the traditional sliding conductivity of the pin bar and the outer shell, this utility model designs a conductive element and an elastic sleeve between the pin bar and the tail plug. Multiple contacts are formed by the elastic contact between the multiple cantilevers on the elastic sleeve and the conductive element. This not only greatly improves the current carrying capacity of the entire connector, but also ensures stable contact with the metal rod under vibration environment by means of the elastic resistance of the cantilevers, thereby achieving anti-vibration protection performance and ensuring the stability of the circuit connection.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4As one embodiment of this utility model, a probe-type vibration-damping connector is disclosed. Specifically, the connector includes a base 1 and a plurality of probe assemblies 2 mounted on the base 1. In this embodiment, the base 1 is an insulator, and the probe assemblies 2 are embedded in the base 1 with both ends protruding. The probe assembly 2 includes a housing 21 and a needle rod 22 slidably connected in the housing 21. A tail plug 23 is fixedly installed at the bottom of the housing 21, and a conductive element 24 is fixedly installed above the tail plug 23. The bottom of the needle rod 22 has a mounting hole 25. The head end of the conductive element 24 slides in the mounting hole 25. An elastic sleeve 3 is provided in the mounting hole 25 to elastically contact the conductive element 24. The elastic sleeve 3 is used to enhance the conductivity between the needle rod 22 and the tail plug 23 to avoid the problem of unstable conductivity in the simple sliding structure under vibration environment.

[0017] In some embodiments, the top of the outer shell 21 of the present invention has an inwardly narrowed opening 26, which can be formed by stamping. The outer side of the needle bar 22 has a stop ring platform 27 that stops on the inner side of the inwardly narrowed opening 26. A spring 28 is placed between the stop ring platform 27 and the tail plug 23.

[0018] In this embodiment, the inner recess 26 and the stop ring 27 are used to limit the sliding of the needle bar 22. The stop ring 27 also functions as a conductive contact. When the needle bar 22 slides with the outer shell 21, the stop ring 27 contacts the inner wall of the outer shell 21 to form a current path. In addition, the spring 28 in this embodiment is sleeved on the outside of the conductive member 24. Its purpose is to move and reset the needle bar 22 so that it can be pushed outward after the connector is disconnected.

[0019] Specifically, in this embodiment, the conductive component 24 includes a metal rod 241 fixed on the tail plug 23, and a limiting ball 242 is fixedly installed at the head end of the metal rod 241. Of course, the outer shell 21 and the needle rod 22 in this utility model are also made of metal, preferably copper. The metal rod 241 is designed to make elastic contact with the elastic kit 3 to form a conductive contact.

[0020] Based on the above embodiments, the elastic kit 3 in this embodiment includes a base ring 31 fixedly installed in the mounting hole 25, and a plurality of cantilever 32 fixedly installed on the base ring 31. The periphery of the plurality of cantilever 32 forms a frustum structure, and the plurality of cantilever 32 contacts the outside of the metal rod 241.

[0021] In other words, in this utility model, by forming multiple cantilever 32 on the upper side of the base ring 31, multiple conductive contacts are constructed between it and the metal rod 241. In this embodiment, four cantilever 32 are preferred, but more can also be provided. The specific number can be selected by those skilled in the art according to actual needs, and no further restrictions are imposed here. Furthermore, the integral molding design between the base ring 31 and the multiple cantilever 32 described in this embodiment can also be made of copper. By leveraging the elastic contact between the multiple cantilever 32 and the metal rod 241 to form multiple contacts, the current carrying capacity of the entire connector can be greatly improved. In a vibration environment, the elastic resistance of the cantilever 32 can ensure a stable contact connection with the metal rod 241, thereby achieving vibration protection performance and ensuring the stability of the circuit connection.

[0022] In some embodiments, the tail plug 23 of this invention includes a connecting section 231 and a plug-in section 232. The plug-in section 232 is plugged into the tail end of the outer shell 21. Of course, the plug-in section 232 and the outer shell 21 are also fixedly connected, such as by welding or riveting. A limiting ring 233 is also formed on the outside of the plug-in section 232. The limiting ring 233 is used to limit and stop the entire insertion process of the tail plug 23. The conductive element 24 is fixedly connected to the plug-in section 232. Obviously, those skilled in the art will know that the tail plug 23 in this embodiment can also be set as a conductive metal part, and its connecting section 231 is used to connect to a conductive part or a circuit board.

[0023] It should be noted that, in this embodiment, the base 1 has several openings 11 on its end face, and the several openings 11 form an elastic cavity inside the base 1. In this embodiment, the openings 11 are set as rectangular openings. By opening multiple rectangular openings inside the base 1, the base 1 has a certain shock absorption and protection capability, thereby further improving the vibration resistance of the entire connector. In addition, in order to facilitate the accurate installation of the base 1 and the connector housing, in this embodiment, a foolproof post 12 is also formed below the base 1.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
