Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and more specifically, to a modular interlocking structure and connecting component. Background Technology
[0002] High-voltage connectors require a high-voltage interlock to monitor the connection status of the plug and socket. A high-voltage interlock (HVIL) is a safety feature designed to use a low-voltage circuit to monitor the integrity of the high-voltage circuit, ensuring that the high-voltage connector is no longer energized after being disconnected, thus protecting personnel who may come into contact with high-voltage components of an electric vehicle from electric shock.
[0003] Existing interlocking structures include interlocking pins housed within the connector housing and mating interlocking terminals housed within the mating connector housing. The interlocking pins are typically U-shaped and fixed to the connector housing via injection molding. The two ends of the U-shape are connected to the corresponding mating interlocking terminals to establish the interlocking signal circuit. However, these injection-molded U-shaped interlocking pins cannot be disassembled or used interchangeably. If requirements change, both the interlocking pins and the connector housing must be discarded and replaced, resulting in high costs. Utility Model Content
[0004] This utility model provides a modular interlocking structure and connecting components to solve the problems of existing interlocking pin technology being unable to be disassembled and assembled and not compatible.
[0005] This utility model provides a modular interlocking structure, which is detachably disposed within a connector for conductive connection with mating interlocking terminals disposed within a mating connector. The modular interlocking structure includes at least two parallel interlocking terminals and a conductive element detachably installed within the connector. The conductive element has at least two insertion holes spaced apart on its end face facing the mating connector. One end of each of the at least two interlocking terminals is detachably installed in the corresponding insertion hole, and the other end extends out of the connector and is conductively connected with the mating interlocking terminals disposed within the mating connector.
[0006] Optionally, the interlocking terminal is a pin-shaped structure, one end of which is formed with a fisheye-shaped structure that matches the plug hole. The interlocking terminal is pressed into the corresponding plug hole through the fisheye-shaped structure.
[0007] Optionally, the two inner walls of the fish-eye structure are respectively formed with staggered first teeth and second teeth. When the interlocking terminal is installed into the corresponding plug hole, the fish-eye structure is squeezed and deformed by the inner wall of the plug hole, so that the first teeth and second teeth mesh.
[0008] Optionally, the inner side of the fish-eye-shaped structure has a fish-eye hole, and at least one of the first tooth and the second tooth is provided in multiples, with the multiple first teeth or second teeth arranged sequentially along the circumference of the fish-eye hole.

[0010] Optionally, the conductive element is embedded in the insulating sleeve by injection molding, and the conductive element has a dumbbell-shaped structure, with two insertion holes located at both ends of the dumbbell-shaped structure.
[0011] This utility model also provides a connection component, including a connector adapted for plugging and a mating connector. The connector is detachably provided with the modular interlocking structure described above. The mating connector is provided with at least two mating interlocking terminals. When the connector and the mating connector are plugged in, at least two of the interlocking terminals are electrically connected to each other.
[0012] Optionally, the connector has a mounting groove facing the mating connector, and the conductive element is embedded and fixed in the mounting groove.
[0013] Optionally, the conductive component is covered with an insulating sleeve, and the insulating sleeve has a clearance hole that exposes the insertion hole. The insulating sleeve and the mounting groove are fixedly connected by an interference fit.
[0014] Optionally, the insertion hole is a through hole structure, and one end of the interlocking terminal abuts against the bottom of the mounting groove.
[0015] This solution has at least the following beneficial effects:
[0016] The modular interlocking structure of this solution is detachably installed inside the connector and includes conductive parts and interlocking terminals that can be detached from the conductive parts. Therefore, the interlocking structure can be set or not set as required, and different models of interlocking terminals can be disassembled and replaced according to actual needs without redesigning the connector. It has high compatibility and low cost for switching between interlocking models of the same type of connector.

It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the present invention.
[0033] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.
[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.
[0035] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0036] like Figure 1-9 As shown, an embodiment of this utility model provides a modular interlocking structure. The modular interlocking structure is detachably disposed in the connector 1 and is used to electrically connect with the mating interlocking terminal 21 disposed in the mating connector 2. The modular interlocking structure includes two parallel interlocking terminals 33 and a conductive element 31 detachably installed in the connector 1. The conductive element 31 has two insertion holes 32 spaced apart on its end face facing the mating connector 2. One end of each of the two interlocking terminals 33 is detachably installed in the corresponding insertion hole 32, and the other end extends out of the connector 1 and is electrically connected with the mating interlocking terminal 21 disposed in the mating connector 2.
[0037] Obviously, in other embodiments, the number of interlocking terminals and plug holes can be set as needed, and the number of mating interlocking terminals of the mating connector is adapted to the number of interlocking terminals.
[0038] The aforementioned modular interlocking structure is detachably installed inside the connector 1 and includes a conductive element 31 and an interlocking terminal 33 that can be detached from the conductive element 31. Therefore, the interlocking structure can be selected or not as needed, and different models of interlocking terminals 33 can be disassembled and replaced according to actual needs without redesigning the connector 1. It has high compatibility and low cost for switching between interlocking models of similar connectors.
[0039] Furthermore, in order to fully utilize the fisheye terminal technology currently known to those skilled in the art, save development costs, and smoothly achieve the purpose of assembly and disassembly, such as Figure 6-8 As shown, in this embodiment, the interlock terminal 33 is a pin-shaped structure. One end of the pin-shaped structure is formed with a fish-eye-shaped structure 35 that matches the insertion hole 32. The interlock terminal 33 is pressed into the corresponding insertion hole 32 through the fish-eye-shaped structure 35 to achieve the detachable and fixed effect of the interlock terminal 33 and the conductive component 31.
[0040] Of course, in other embodiments, the interlocking terminal can also be connected to the conductive component through conventional technologies such as snap-fit structures to meet the requirements of detachability and fixation. The interlocking terminal can also be a conductive structure that can be implemented by other existing technologies and is compatible with the mating interlocking terminal.
[0041] Furthermore, in order to enhance the structural strength of the fisheye-shaped structure 35 and meet the requirements for fixation strength, such as Figure 7As shown, in this embodiment, the two inner walls of the fisheye structure 35 are respectively formed with staggered first teeth 352 and second teeth 353. When the interlocking terminal 33 is installed into the corresponding insertion hole 32, the fisheye structure 35 is squeezed and deformed by the inner wall of the insertion hole 32, so that the first teeth 352 and second teeth 353 mesh.
[0042] In more detail, the inner side of the aforementioned fisheye-shaped structure 35 has a fisheye hole 351. The fisheye hole 351 is a through-hole structure with its axis perpendicular to the disassembly / assembly direction of the interlocking terminal 33. At least one of the first tooth 352 and the second tooth 353 is provided in multiples, and the multiple first teeth 352 or second teeth 353 are arranged sequentially along the circumference of the fisheye hole 351. Figure 7 As shown, in this embodiment, there are two second teeth 353 and one first tooth 352, and the first tooth 352 meshes with the second tooth 353.
[0043] Furthermore, in order to meet the assembly requirements with connector 1 and achieve better assembly results, the outer side of conductive component 31 is covered with an insulating sleeve 3, and the insulating sleeve 3 is provided with a clearance hole 34 to expose the insertion hole 32.
[0044] like Figure 3 , 5 As shown in Figures 6 and 8, in this embodiment, the insulating sleeve 3 wraps around the periphery of the conductive component 31, thereby forming a clearance hole 34 that allows the entire side of the conductive component 31 to be exposed. The insulating sleeve 3 and the conductive component 31 are formed by an embedded injection molding process, that is, the conductive component 31 is embedded in the insulating sleeve 3, which satisfies the fixed connection requirements and fixed strength requirements between the two. In addition, the conductive component 31 has a dumbbell-shaped structure, which further improves the connection strength between the conductive component 31 and the insulating sleeve 3. There are two insertion holes 32 located at both ends of the dumbbell-shaped structure.
[0045] At the same time, such as Figure 1-5 As shown, an embodiment of the present invention also provides a connection component, including a connector 1 and a mating connector 2 for plugging and mating. The connector 1 is detachably provided with the modular interlocking structure as described above. The mating connector 2 is provided with two mating interlocking terminals 21. When the connector 1 and the mating connector 2 are plugged in, the two interlocking terminals 33 and the two mating interlocking terminals 21 are electrically connected to each other.
[0046] Furthermore, in order to achieve the modular interlocking structure and the detachable installation of connector 1, such as... Figure 3-5As shown, in this embodiment, the connector 1 is provided with a mounting groove 11 facing the mating connector 2. The conductive element 31 is embedded and fixed in the mounting groove 11. In fact, since the conductive element 31 is covered with an insulating sleeve 3 in this embodiment, the conductive element 31 is embedded and fixed in the mounting groove 11 through the insulating sleeve 3. The insulating sleeve 3 is provided with a clearance hole 34 that exposes the insertion hole 32. The insulating sleeve 3 and the mounting groove 11 are fixedly connected by an interference fit.
[0047] Of course, in other embodiments, the insulating sleeve and the mounting groove can also be fixedly connected by conventional connection structures such as snap-fit structures.
[0048] In addition, such as Figure 3 As shown, in this embodiment, the insertion hole 32 is a through hole structure, and one end of the interlocking terminal 33 abuts against the bottom of the mounting groove 11.
[0049] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
