Description

Technical Field

[0001] This application relates to the technical field of connectors, and in particular to a connector mating structure. Background Technology

[0002] In fields such as electronic equipment, automotive electronics, and industrial control, connectors are key components for achieving circuit conduction and signal transmission. The reliability of the male and female plug-in structure directly determines the stable operation of the entire system.

[0003] Most mainstream connector mating structures currently employ traditional metal pin-hole mating and snap-fit ​​positioning designs. They achieve electrical connection by relying on the elastic pressure between metal contacts and limit axial displacement after mating through the snap-fit ​​structure, thereby ensuring reliable electrical signal connection.

[0004] However, in applications involving continuous vibration or impact, such as automobile driving and industrial machinery operation, even if the axial displacement of the plug-in structure is limited, the contact surface will still wear or oxidize due to long-term small displacement, resulting in insufficient contact pressure and increased contact resistance. Sometimes, it may even cause stress concentration inside the mechanical structure, causing serious damage to the mechanical structure and short circuit, which will result in unstable signal transmission and poor current conduction. Summary of the Invention

[0005] To ensure stable electrical signal connection, this application provides a connector insertion structure.

[0006] The connector insertion structure provided in this application adopts the following technical solution: A connector insertion structure includes a first electrical connection plate, a flexible electrical connection plate, and a second electrical connection plate. The flexible electrical connection plate includes a first wear portion and a second wear portion. The first electrical connection plate is movable and presses against the first wear portion, thereby deforming the flexible electrical connection plate and causing the second wear portion to press against the second electrical connection plate.

[0007] By adopting the above technical solution, the first electrical connection board is used as the input terminal, and the second electrical connection board and the flexible electrical connection board are used as output terminals. The connection between the first electrical connection board and the flexible electrical connection board is completed by moving the first electrical connection board to press against the first wear part. At this time, the first wear part being pressed will cause the second wear part to press against the second electrical connection board, and the flexible electrical connection board will connect with the second electrical connection board. The electrical signal connection of this application has two paths: one is that the first electrical connection board acts as the input, and the contact between the first wear part and the first electrical connection board causes the flexible electrical connection board to act as the output; the other is that the first electrical connection board acts as the input, and the contact between the second wear part of the flexible electrical connection board and the second electrical connection board causes the second electrical connection board to act as the output. This can ensure the stability of the electrical signal connection as much as possible. In a multi-vibration environment, the first electrical connection board will rub against the first wear part, and the second electrical connection board will rub against the second wear part. The first and second wear parts will be worn down by friction, but the stability of the electrical signal connection can still be guaranteed.

[0008] Preferably, the elastic electrical connection plate includes a first sub-plate, a second sub-plate, and a third sub-plate connected in sequence. The second sub-plate is inclined to the first sub-plate in a direction away from the first electrical connection plate, and the third sub-plate is inclined to the second sub-plate in a direction close to the first electrical connection plate. The first wear portion is formed at the connection between the first sub-plate and the second sub-plate, and the second wear portion is formed at the connection between the second sub-plate and the third sub-plate.

[0009] By adopting the above technical solution, when the present application is under vibration, since the first sub-plate, the second sub-plate and the third sub-plate all have elastic deformation capability, the contact between the first wear part and the first electrical connection plate and the contact between the second wear part and the second electrical connection plate can be floating. The elastic electrical connection plate can be slightly displaced relative to the first electrical connection plate and the second electrical connection plate. This design can prevent damage to the elastic electrical connection plate structure.

[0010] Preferably, the first electrical connection plate is connected to the first base body, the second electrical connection plate is connected to the second base body, and the elastic electrical connection plate further includes a connecting plate connected to the end of the first sub-plate away from the second sub-plate, the connecting plate being connected to the second base body; The elastic electrical connection plate has a broken circuit position and a closed circuit position. When the elastic electrical connection plate is in the broken circuit position, it is separated from both the first and second electrical connection plates. When the elastic electrical connection plate is in the closed circuit position, it is in contact with both the first and second electrical connection plates. The first seat moves away from the second seat along the direction of the first electrical connection plate and / or the second seat moves away from the first seat along the direction of the connecting plate, so that the flexible electrical connection plate switches between a broken position and a closed position.

[0011] By adopting the above technical solution, the switching between the path and the break of the electrical signal connection can be easily completed by separating the first and second seats.

[0012] Preferably, the connecting plate is inclined to the first sub-plate in a direction close to the first electrical connecting plate. The connecting plate and the first base are slidably connected, and the connecting plate and the first base are detachably connected to a locking member. The first base has a first pressing part and a second pressing part. When the locking member is removed, the elastic electrical connecting plate is moved away from the first base along the direction of the connecting plate. The first pressing part presses against the first sub-plate, causing the elastic electrical connecting plate to separate from the first electrical connecting plate. The second pressing part presses against the second sub-plate, causing the elastic electrical connecting plate to separate from the second electrical connecting plate.

[0013] By adopting the above technical solution, after the locking component is removed, when the elastic electrical connection plate moves away from the first base body along the connecting plate setting direction, the first pressing part presses against the first sub-plate, causing the elastic electrical connection plate to separate from the first electrical connection plate, and the second pressing part presses against the second sub-plate, causing the elastic electrical connection plate to separate from the second electrical connection plate. This design allows for a reliable and forced disconnection of the electrical signal connection without separating the first base body and the second base body.

[0014] Preferably, the first wear portion has a first contact surface, and the second wear portion has a second contact surface. When the elastic electrical connection plate is in the open circuit position, the first contact surface is in contact with the first electrical connection plate, and the second contact surface is in contact with the second electrical connection plate.

[0015] By adopting the above technical solution, the above design ensures that after the elastic electrical connection plate is deformed by the first electrical connection plate, the contact area between the first electrical connection plate and the first wear part and the contact area between the second electrical connection plate and the second wear part are as large as possible, thereby ensuring the stability of the electrical signal connection.

[0016] Preferably, the cross-section of the first worn portion gradually increases in the direction away from the first electrical connector in the direction in which the first electrical connector is installed.

[0017] By adopting the above technical solution, when the present application is in a vibration environment for a long time, the first electrical connection plate may wear the first wear part. The structural design of the first wear part of the present application makes the area of ​​the worn surface on the first wear part larger and larger over time, that is, as the wear of the first wear part intensifies. The increase in area will make it more and more difficult for the first wear part to be worn. Of course, the micro-movement capability of the elastic electrical connection plate will decrease accordingly. The present application also ensures the stability of the electrical signal connection to a certain extent after long-term use.

[0018] Preferably, the flexible electrical connection plate is provided in multiple forms.

[0019] By adopting the above technical solution, when some of the flexible electrical connection boards are short-circuited, the other flexible electrical connection boards can maintain a stable electrical signal connection.

[0020] Preferably, the second housing has a guide portion and a plug-in groove located on one side of the guide portion, the first wear portion and the second wear portion are both located in the plug-in groove, the guide portion has a guide slope, the guide slope is used to guide the first electrical connector to be inserted into the plug-in groove and contact the first wear portion.

[0021] By adopting the above technical solution, the guide slope can guide the first electrical connector plate to be inserted into the plug slot, thereby pressing against the first wear part and completing the connection.

[0022] Preferably, the first base has a mounting hole, and a snap-fit ​​component is engaged in the mounting hole, with the first electrical connection plate connected to the snap-fit ​​component.

[0023] By adopting the above technical solution, the snap-fit ​​component along with the first electrical connector can be disassembled.

[0024] Preferably, the snap-fit ​​component includes two elastic snap-fit ​​plates, and a snap-fit ​​groove is formed between the two elastic snap-fit ​​plates, with the first electrical connector snapped into the snap-fit ​​groove.

[0025] By adopting the above technical solution, the first electrical connector can be disassembled.

[0026] In summary, the present invention has at least one of the following beneficial technical effects: 1. In this application, if the first electrical connection board is used as the input terminal, and the second electrical connection board and the flexible electrical connection board are used as output terminals, the connection between the first electrical connection board and the flexible electrical connection board is completed by moving the first electrical connection board to press against the first wear part. At this time, after the first wear part is pressed, the second wear part presses against the second electrical connection board, and the flexible electrical connection board connects with the second electrical connection board. The electrical signal connection of this application has two paths: one is that the first electrical connection board acts as the input, and the contact between the first wear part and the first electrical connection board causes the flexible electrical connection board to act as the output; the other is that the first electrical connection board acts as the input, and the contact between the second wear part of the flexible electrical connection board and the second electrical connection board causes the second electrical connection board to act as the output. This can ensure the stability of the electrical signal connection as much as possible. In a multi-vibration environment, the first electrical connection board will rub against the first wear part, and the second electrical connection board will rub against the second wear part. The first and second wear parts will be worn down by friction, but the stability of the electrical signal connection can still be guaranteed. 2. When the present application is under vibration, since the first sub-plate, the second sub-plate and the third sub-plate all have elastic deformation capability, the contact between the first wear part and the first electrical connection plate and the contact between the second wear part and the second electrical connection plate can be floating. The elastic electrical connection plate can be slightly displaced relative to the first electrical connection plate and the second electrical connection plate. This design can prevent damage to the elastic electrical connection plate structure. 3. After the locking component is removed, as the flexible electrical connecting plate moves away from the first base body along the connecting plate's setting direction, the first pressing part presses against the first sub-plate, causing the flexible electrical connecting plate to separate from the first electrical connecting plate, and the second pressing part presses against the second sub-plate, causing the flexible electrical connecting plate to separate from the second electrical connecting plate. This design allows for a reliable and forced disconnection of the electrical signal connection without separating the first and second base bodies. 4. After the elastic electrical connector is deformed by the first electrical connector, the contact area between the first electrical connector and the first wear portion, and the contact area between the second electrical connector and the second wear portion are relatively large, which ensures the stability of the electrical signal connection. When this application is in a vibration environment for a long time, the first electrical connector may wear down the first wear portion. The structural design of the first wear portion in this application makes the area of ​​the worn surface on the first wear portion increase over time, that is, as the wear of the first wear portion intensifies. The increase in area makes it more and more difficult for the first wear portion to be worn down. Of course, the micro-motion capability of the elastic electrical connector will decrease accordingly. This application also ensures the stability of the electrical signal connection to a certain extent after long-term use. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0031] This application discloses a connector insertion structure to ensure that the electrical signal connection is less prone to instability due to long-term vibration.

[0032] Reference Figure 1 and Figure 2 The connector's mating structure includes a first base 1 and a second base 2 that can be engaged. The first base 1 includes a connecting groove 11, and the second base 2 includes a mating plate 21, which is engaged with the connecting groove 11. The mating plate 21 can be disengaged from the connecting groove 11 by separating the first base 1 and the second base 2.

[0033] Reference Figure 2 and Figure 3 The first base 1 has a mounting hole 12, and a snap-fit ​​component 13 is engaged with the mounting hole 12. The snap-fit ​​component 13 is connected to a first electrical connection plate 14, which is vertically arranged. Specifically, the snap-fit ​​component 13 includes an elastic hook 131 at its end, and the mounting hole 12 has a mating surface 121, on which the elastic hook 131 engages.

[0034] Reference Figure 2 and Figure 3 The snap-fit ​​component 13 includes two elastic snap-fit ​​plates 132 at its bottom end, with a snap-fit ​​groove 133 formed between the two snap-fit ​​plates. The first electrical connection plate 14 snaps into the snap-fit ​​groove 133, and the two elastic snap-fit ​​plates 132 press and fix the first electrical connection plate 14. This facilitates the removal of the first electrical connection plate 223 along with the snap-fit ​​component 13, and allows for the subsequent separate removal of the first electrical connection plate 14 for inspection or replacement.

[0035] Reference Figure 4 , Figure 5 and Figure 6 The second base 2 is detachably provided with an elastic electrical connection plate 22 and a second electrical connection plate 23. The second electrical connection plate 23 is located to the right of the elastic electrical connection plate 22, and the first electrical connection plate 14 is located to the left of the elastic electrical connection plate 22. The elastic electrical connection plate 22 includes a first wear portion 221 and a second wear portion 222. When the first electrical connection plate 14 is moved downward and pressed against the first wear portion 221, the elastic electrical connection plate 22 will deform, causing the second wear portion 222 to press against the second electrical connection plate 23.

[0036] If the first electrical connection plate 14 is used as the input terminal of the electrical signal, and the second electrical connection plate 23 and the flexible electrical connection plate 22 are used as the output terminals of the electrical signal, the connection between the first electrical connection plate 14 and the flexible electrical connection plate 22 is completed by moving the first electrical connection plate 14 to press against the first wear part 221. At this time, after the first wear part 221 is pressed, the second wear part 222 will press against the second electrical connection plate 23, and the flexible electrical connection plate 22 will be connected to the second electrical connection plate 23.

[0037] This application can ensure a stable connection of electrical signals. The electrical signal connection has two paths: one is that the first electrical connection plate 14 is used as the input, and the contact between the first wear part 221 and the first electrical connection plate 14 makes the elastic electrical connection plate 22 the output; the other is that the first electrical connection plate 14 is used as the input, and the contact between the second wear part 222 of the elastic electrical connection plate 22 and the second electrical connection plate 23 makes the second electrical connection plate 23 the output.

[0038] The flexible electrical connection plate 22 has a broken circuit position and a closed circuit position. When the flexible electrical connection plate 22 is in the broken circuit position, it is separated from both the first electrical connection plate 14 and the second electrical connection plate 23. At this time, the first base 1 and the second base 2 are separated. When the flexible electrical connection plate 22 is in the closed circuit position, it is in contact with both the first electrical connection plate 14 and the second electrical connection plate 23. At this time, the first base 1 and the second base 2 are engaged. The first seat 1 can move vertically away from the second seat 2, or the second seat 2 can move vertically away from the first seat 1, so that the flexible electrical connecting plate 22 can switch between the open circuit position and the closed circuit position. Of course, the two actions can be performed simultaneously.

[0039] Reference Figure 4 , Figure 5 and Figure 6 To further ensure the stability of the electrical signal connection, multiple flexible electrical connection plates 22 are provided. In this embodiment, two flexible electrical connection plates 22 are provided, and the two flexible electrical connection plates 22 are arranged along the front-back direction. The number of flexible electrical connection plates 22 is mainly determined by the overall size design of the second base 2 and the first base 1.

[0040] Reference Figure 4 , Figure 5 and Figure 6The flexible electrical connection plate 22 includes a connecting plate 223, a first sub-plate 224, a second sub-plate 225, and a third sub-plate 226 connected sequentially from bottom to top. The connecting plate 223 is detachably connected to the second base 2. The connecting plate 223 is vertically arranged and is inclined relative to the first sub-plate 224 in the direction of the first electrical connection plate 14. The second sub-plate 225 is inclined away from the first sub-plate 14 from the first sub-plate 224. The third sub-plate 226 is inclined towards the second sub-plate 225 from the first electrical connection plate 14. A first wear portion 221 is formed at the connection between the first sub-plate 224 and the second sub-plate 225, and a second wear portion 222 is formed at the connection between the second sub-plate 225 and the third sub-plate 226.

[0041] When this application is under vibration, since the first sub-plate 224, the second sub-plate 225 and the third sub-plate 226 all have elastic deformation capabilities, the contact between the first wear part 221 and the first electrical connection plate 14 and the contact between the second wear part 222 and the second electrical connection plate 23 can be floating. The elastic electrical connection plate 223 can be slightly displaced relative to the first electrical connection plate 14 and the second electrical connection plate 23. This design can prevent damage to the structure of the elastic electrical connection plate 22.

[0042] Reference Figure 4 , Figure 5 and Figure 6 The second base 2 has a guide portion 24, a first pressing portion 25, and a second pressing portion 26 arranged sequentially from left to right. A insertion groove 27 is formed between the guide portion 24 and the second pressing portion 26. A receiving groove 1 251 is also formed between the first pressing portion 25 and the second pressing portion 26. A receiving groove 261 is formed between the second pressing portion 26 and the second base 2, located to the right of the second pressing portion 26. A connecting plate 223 is detachably inserted into the receiving groove 1 251 via a locking member, and the connecting plate 223 can slide up and down relative to the receiving groove 1 251. A second electrical connecting plate 23 is also detachably inserted into the receiving groove 261 via a locking member, and the second electrical connecting plate 23 can also slide up and down relative to the receiving groove 261. Specifically, fasteners include screws, pins, etc.

[0043] After the locking mechanism is removed, as the flexible electrical connection plate 22 moves vertically away from the first base 1, the first pressing part 25 presses against the first sub-plate 224, causing the flexible electrical connection plate 22 to separate from the first electrical connection plate 223, i.e., the first wear part 221 to separate from the first electrical connection plate 14. Subsequently, the second pressing part 26 presses against the second sub-plate 225, causing the flexible electrical connection plate 22 to separate from the second electrical connection plate 23, i.e., the second wear part 222 to separate from the second electrical connection plate 23. This design allows for a forced and reliable disconnection of the electrical signal connection simply by moving the flexible electrical connection plate 22 downwards without separating the first base 1 and the second base 2.

[0044] Reference Figure 5 and Figure 6 To ensure a stable electrical signal connection, the first wear portion 221 has a first contact surface 2211, and the second wear portion 222 has a second contact surface 2221. When the elastic electrical connection plate 22 is in the open circuit position, the first contact surface 2211 is in contact with the first electrical connection plate 14, and the second contact surface 2221 is in contact with the second electrical connection plate 23. Specifically, to achieve the above-mentioned stable electrical signal connection, in this embodiment, the included angle between the first sub-plate 224 and the connecting plate 223 is 160°, the included angle between the second sub-plate 225 and the first sub-plate 224 is 125°, and the included angle between the third sub-plate 226 and the second sub-plate 225 is 140°.

[0045] The above design maximizes the contact area between the first electrical connection plate 14 and the first wear part 221, and the contact area between the second electrical connection plate 23 and the second wear part 222, after the elastic electrical connection plate 22 is deformed by the first electrical connection plate 14, thereby ensuring the stability of the electrical signal connection.

[0046] It should be noted that when the first electrical connecting plate 14 is not pressing against the first wear portion 221, both the first contact surface 2211 and the second contact surface 2221 are inclined downwards from left to right. When the first electrical connecting plate 14 presses against the first wear portion 221, the first contact surface 2211 will be vertically arranged and in contact with the right end face of the first electrical connecting plate 14, and the second contact surface 2221 will be vertically arranged and in contact with the left end face of the second electrical connecting plate 23.

[0047] Reference Figure 5 and Figure 6 When the first wear portion 221 is pressed against the first electrical connection plate 14, the cross-section of the first wear portion 221 in the vertical direction gradually increases in the direction away from the first electrical connection plate 14.

[0048] When this application is in a vibration environment for a long time, the first electrical connection plate 14 may wear the first wear portion 221. The structural design of the first wear portion 221 in this application makes the area of ​​the worn surface on the first wear portion 221 larger and larger over time, that is, as the wear of the first wear portion 221 intensifies. The increase in area makes it more and more difficult for the first wear portion 221 to be worn. Of course, due to the increase in contact area, the resistance to the micro-movement of the elastic electrical connection plate 22 will increase, and the micro-movement capability of the elastic electrical connection plate 22 will decrease accordingly. This application also ensures the stability of the electrical signal connection to a certain extent after long-term use.

[0049] Reference Figure 5In order to facilitate the insertion of the first electrical connector 14 into the plug slot 27 to press against the first wear part 221, both the first wear part 221 and the second wear part 222 are located in the plug slot 27. The guide part 24 has a guide slope 241, which slopes downward from left to right.

[0050] The implementation principle of the connector insertion structure in this embodiment is as follows: if the first electrical connection plate 14 is used as the input end, and the second electrical connection plate 23 and the elastic electrical connection plate 22 are used as the output ends, by making the first base 1 and the second base 2 snap together, the first electrical connection plate 14 will move and press against the first wear part 221 to complete the connection between the first electrical connection plate 14 and the elastic electrical connection plate 22. At this time, after the first wear part 221 is pressed, the second wear part 222 will press against the second electrical connection plate 23, and the elastic electrical connection plate 22 will connect with the second electrical connection plate 23.

[0051] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
