Description

Technical Field

[0001] This utility model relates to the field of contact body technology, specifically an interlocking bidirectional contact body. Background Technology

[0002] With the vigorous development of the new energy industry, new energy connectors are being used more and more widely in various devices. The connector contact is a key component in the connector used to achieve electrical connection. The connector contact is the part of the connector that directly makes electrical connection with external circuits or equipment. By contacting the corresponding contact or conductor, the transmission of current and signals is realized. It is the core component that ensures that the connector can work normally.

[0003] Most existing contacts only support unidirectional current or signal transmission. In new energy applications, many scenarios require bidirectional transmission capabilities. For example, in vehicle-to-grid technology, electric vehicles not only need to obtain power from the grid for charging, but also need to transmit the power from the battery back to the grid under certain circumstances. Traditional unidirectional contacts cannot meet the needs of this bidirectional energy interaction.

[0004] Therefore, an interlocking bidirectional contactor is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an interlocking bidirectional contact body, which aims to solve the problems in the prior art.

[0006] To achieve the above objectives, one embodiment of the present invention provides an interlocking bidirectional contact body, comprising:

[0007] Conductive substrate;

[0008] A receiving hole is formed inside the conductive body. One end of the conductive body is provided with a socket 1 that communicates with the receiving hole. The socket 1 is used to allow the plug terminal to enter the interior of the receiving hole. The end of the conductive body away from the socket 1 is provided with a socket 2. The diameter of the socket 2 is smaller than the diameter of the socket 1.

[0009] An inner mesh spring structure is disposed inside the receiving hole. The inner mesh spring structure is used to clamp and fix the plug terminals inserted into the receiving hole so that the plug terminals are stably connected to the conductive body.

[0010] The connector is connected to the outer peripheral surface of the conductive body at the end furthest from the socket.

[0011] A connector is disposed on the conductive body, the connector being used to stably connect the end of the conductive body away from the socket to an external device.

[0012] Preferably, the inner mesh spring structure includes end rings and spring plates. There are two end rings, which are symmetrically arranged inside the receiving hole. There are multiple spring plates, with each end of the multiple spring plates connected to an end ring. The multiple spring plates are bent inwards towards the end rings, and the bending angle of the spring plates is an obtuse angle. Multiple conductive contacts are connected to the outer circumferential surface of each end ring.

[0013] Preferably, the connector includes a limiting ring and an outer spiral elastomer. There are multiple limiting rings, which are distributed at intervals on the outer peripheral surface of the conductive body. There are multiple outer spiral elastomers, one of which is disposed between two adjacent limiting rings.

[0014] Preferably, the inner wall of the first socket is provided with a chamfer for the insertion transition.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By incorporating an inner spring structure, socket one, socket two, and connectors on the conductive body, the contact can perform bidirectional current transmission operations and support forward and reverse insertion functions. This enables the charging of electric vehicles and the reverse transmission of electrical energy from the battery back to the power grid. Furthermore, it can be adapted to device terminals of different sizes, expanding the applicability of the contact structure and improving its practicality. Attached Figure Description

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] like Figures 1 to 5 As shown, an interlocking bidirectional contactor includes a conductive body 10, with a receiving hole 101 inside the conductive body 10. One end of the conductive body 10 has a socket 102 communicating with the receiving hole 101. The socket 102 is used to allow plug terminals to enter the receiving hole 101. An inner mesh spring structure 20 is provided inside the receiving hole 101 to clamp and fix the plug terminals inserted into the receiving hole 101, so that the plug terminals are stably connected to the conductive body 10. A second socket 103 is provided at the end of the conductive body 10 away from the first socket 102. The diameter of the second socket 103 is smaller than the diameter of the first socket 102. A connector 30 is connected to the outer peripheral surface of the end of the conductive body 10 away from the first socket 102. A connector is provided on the conductive body 10 to stably connect the end of the conductive body 10 away from the first socket 102 to an external device.

[0025] During use, the external plug terminal is inserted into the socket 102 and fixed by the inner mesh spring structure 20. It is then connected to the socket of the external device through the conductive body 10, and the connection stability between the conductive body 10 and the external device socket is ensured by the connector.

[0026] In practical use, the external plug terminals can be the metal terminals of the charging gun. The metal terminals of the charging gun are cylindrical. When forward charging is required, i.e., the power grid charges the vehicle, the metal terminals of the charging gun are inserted into the interior of the conductive body 10 through the socket 102, and the metal terminals of the charging gun are clamped and fixed by the inner mesh spring structure 20. The other end of the conductive body 10 and the connecting seat 30 can be connected to the dedicated slot of the power grid interface. The other end of the conductive body 10 is fixed by the connector to ensure the stability of the connection between the other end of the conductive body 10 and the dedicated slot of the power grid interface. At this time, the current flow is: power grid → power grid terminal → conductive body 10 → inner mesh spring → charging gun terminal → vehicle battery. If reverse charging is required... During discharge, the plug of the vehicle interface is inserted into the second socket 103 and connected to the vehicle terminal via the connector. At this time, the first socket 102 of the conductive body 10 is connected to the terminal of the power grid plug. The terminal of the power grid plug is clamped and fixed by the inner mesh spring structure 20. At this time, the current flow is: vehicle battery → vehicle terminal → conductive body 10 → inner mesh spring structure 20 → power grid terminal → power grid. Both ends of the conductive body 10 are provided with sockets to support the plug to be inserted from both ends of the conductive body 10, so that the contact can perform bidirectional current transmission operation, and the contact can support forward and reverse insertion and interchange of power grid / vehicle terminals. It can also be adapted to power grid and vehicle terminals of different sizes, improving the practicality of the contact structure.

[0027] It should be noted that the shape of the connector 30 is the same as that of the dedicated slot for the power grid interface, which allows the connector 30 to be connected to the dedicated slot for the power grid interface more stably.

[0028] like Figure 1-4 The inner spring structure 20 includes two end rings 21. Multiple spring plates 22 are connected to the opposite side of the two end rings 21. The multiple spring plates 22 are bent inward into the end rings 21. The bending angle of the spring plates 22 is an obtuse angle. Multiple conductive contacts 23 are connected to the outer peripheral surface of each end ring 21. The multiple conductive contacts 23 are distributed in a circumferential array on the outer peripheral surface of the end ring 21. The multiple conductive contacts 23 are all in contact with the inner wall of the receiving hole 101.

[0029] When the plug terminal is inserted into the receiving hole 101 through the socket 102, the multiple spring plates 22 will deform and, under the reaction force of the multiple spring plates 22, will fit tightly with the plug terminal, thereby clamping and fixing the plug terminal, making the fixing operation of the plug segment relatively simple. At this time, the current can be conducted to the conductive body 10 through the spring plates 22, the end ring 21 and the conductive contact 23.

[0030] It should be noted that the outer diameter of the end ring 21 is matched with the diameter of the receiving hole 101, and the maximum distance between the two end rings 21 is the same as the depth of the receiving hole 101, so as to avoid the end rings 21 from shifting position and ensure the positional stability of the end rings 21.

[0031] like Figure 1-3 and Figure 5 The connector includes multiple limiting rings 11 installed on the outer peripheral surface of the conductive body 10, and an outer spiral elastomer 12 is provided between two adjacent limiting rings 11. The outer spiral elastomer 12 is sleeved on the outer peripheral surface of the conductive body 10.

[0032] When the end of the connector 30 and the conductive body 10 away from the socket 102 is connected to an external device, the outer spiral elastomer 12 will undergo radial deformation. The reaction force of the outer spiral elastomer 12 can axially lock the end of the connector 30 and the conductive body 10 away from the socket 102, thereby preventing displacement of the conductive body 10 during insertion and removal. Furthermore, the outer spiral elastomer 12 can absorb the lateral vibration generated during insertion and removal, avoiding poor contact between the conductive body and the device interface due to displacement. It can also buffer external vibrations, greatly minimizing the impact of external vibrations on the conductive body 10.

[0033] Multiple limiting rings 11 can prevent two adjacent outer spiral elastomers 12 from sliding and interfere with each other, thus avoiding axial locking failure due to the sliding of the outer spiral elastomers 12, ensuring the connection stability between the conductive body 10 and the external device. The number of limiting rings 11 and outer spiral elastomers 12 can be designed according to the actual situation during use.

[0034] It should be noted that the maximum distance between the outer spiral elastomer 12 and the center line of the conductive body 10 is greater than the maximum distance between the connector 30 and the center line of the conductive body 10, so that the outer spiral elastomer 12 can contact the external device and lock the conductive body 10.

[0035] like Figure 1 , Figure 3 and Figure 5 The inner wall of the socket 102 is provided with a plug transition chamfer 104, which is used to make the plug terminals more smoothly inserted into the receiving hole 101.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
