[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] In the automotive industry, connectors need to be connected to various components without error, such as central control, domain control, camera, lidar, etc. Connectors at each position of the car also need to be foolproof to prevent incorrect connection of car connectors, such as the front camera, rear camera, roof camera, left rearview mirror camera, right rearview mirror camera, front bumper radar, rear bumper radar, and roof scanning radar, etc. Different regional domain controls use different connectors.

[0037] The embodiments of the present application provide a connector, a female connector, a connector assembly and a connector combination, which can solve the technical problem in the related art that only one fool-proof structure is provided on the male connector and the female connector, and a large number of male connectors and female connectors cannot correspond one to one.

[0038] See also Figure 1 As shown, a connector provided by an embodiment of the present application may include: a connector housing 1, wherein the connector housing 1 has N foolproofing positions 11 at different positions, and any N / 2 or (N±1) / 2 of the foolproofing positions 11 are randomly selected to be provided with a first foolproofing portion 12 ( Figure 2 As shown), N is a positive integer greater than or equal to 1; when N is an even number, the connector housing 1 is provided with N / 2 of the first fool-proofing parts 12; when N is an odd number, the connector housing 1 is provided with (N±1) / 2 of the first fool-proofing parts 12.

[0039] In this embodiment, the connector can be a male connector or a female connector, and the first foolproofing part 12 can be a directional key or a directional slot. When the connector is a male connector, the first foolproofing part 12 is preferably a directional key, and when the connector is a female connector, the first foolproofing part 12 is preferably a directional slot. In order to completely prevent the male connector and the female connector (or adapter) from being inserted incorrectly and to minimize the number of first foolproofing parts 12, at the beginning of the design, it is necessary to plan the number and position of the foolproofing setting positions 11. In this embodiment, N foolproofing setting positions 11 are planned. The distribution positions of these N foolproofing setting positions 11 on the connector housing 1 are different, and they can be adjacent to each other or separated from each other. This embodiment preferably uses a male connector as the connector for explanation. In order to maximize the number of combinations of the first foolproof portion 12 and to achieve a one-to-one correspondence between the male connector and the female connector after the first foolproof portion 12 is set on the male connector, this embodiment selects N / 2 (N is an even number) or (N±1) / 2 (N is an odd number) foolproof setting positions 11 from the planned N foolproof setting positions 11 to set the first foolproof portion 12 in the connector for use in a specific scenario, so that the male connector and the female connector can not only be inserted into each other, but also achieve a one-to-one correspondence. N in this embodiment can be a positive integer such as 1, 2, 3, 4, 5 or 6.

[0040] In this embodiment, N foolproof setting positions 11 with different positions are planned on the connector housing 1, and the N foolproof setting positions 11 with different positions are arranged and combined to obtain a plurality of combination forms of each group of N / 2 or (N±1) / 2 foolproof setting positions 11. Different combination forms have at least one foolproof setting position 11 with different positions, and different connectors select different combinations of foolproof setting positions 11, that is, N / 2 or (N±1) / 2 foolproof setting positions 11 are selected on each connector housing 1, and the first foolproof setting positions 11 are set on these foolproof setting positions 11. An anti-idiot part 12, but different connector housings 1 have at least one first anti-idiot part 12 at a different position, so that multiple connectors can be distinguished by N / 2 or (N±1) / 2 first anti-idiot parts 12 thereon to dock with a unique matching docking connector. The arrangement of the first anti-idiot part 12 in this embodiment can distinguish a large number of connectors one by one and has the most combination forms, which solves the technical problem in the related art that only one anti-idiot structure is provided on the male connector and the female connector, and a large number of male connectors and female connectors cannot correspond one to one.

[0041] Due to the small installation space on the vehicle, the volume of the connector is required to be high. In order to achieve a better foolproofing effect, the first foolproofing portion 12 needs to have a certain volume to have an effective foolproofing capability in a limited space. In view of this contradiction, in a preferred embodiment, multiple foolproofing sections are provided on the space of the connector to achieve more foolproofing effects in a limited space. Figure 1 and Figure 2 As shown, in this embodiment, the connector housing 1 has a first anti-foolproof zone 13 and a second anti-foolproof zone 14, and the first anti-foolproof zone 13 and the second anti-foolproof zone 14 are distributed along the axial direction of the connector housing 1; among the N anti-foolproof setting positions 11, some of the anti-foolproof setting positions 11 are located in the first anti-foolproof zone 13, and some of the anti-foolproof setting positions 11 are located in the second anti-foolproof zone 14.

[0042] In this embodiment, when planning N fool-proof setting positions 11, two areas for arranging the fool-proof setting positions 11 are selected on the connector housing 1, namely, a first fool-proof area 13 and a second fool-proof area 14 distributed along the axial direction. Among the N fool-proof setting positions 11, a part of the fool-proof setting positions 11 are planned in the first fool-proof area 13, and a part of the fool-proof setting positions 11 are planned in the second fool-proof area 14. Each connector housing 1 is actually provided with N / 2 or (N±1) / 2 fool-proof setting positions 11 of the first fool-proof part 12. The fool-proof setting positions 11 can be selected from the first fool-proof area 13, or can be selected from the second fool-proof area 14. By setting at least two fool-proof areas along the axial direction of the connector, it is ensured that more connectors can be distinguished and the size of the connector is small.

[0043] In other embodiments, it is also possible not to set two or more fool-proof areas, and it is also possible to plan the N fool-proof setting positions 11 at different positions in the same area of ​​the connector.

[0044] Further, in one embodiment, see Figure 2 As shown, relative to the second fool-proof zone 14, the first fool-proof zone 13 is biased towards the docking surface of the connector housing 1, and the number of the fool-proof setting positions 11 in the first fool-proof zone 13 is less than the number of the fool-proof setting positions 11 in the second fool-proof zone 14; among the N / 2 or (N±1) / 2 first fool-proof parts 12 set on the connector housing 1, at least part of the first fool-proof parts 12 are located in the second fool-proof zone 14. In the present embodiment, the mating surface of the connector housing 1 is located at the front end of the connector housing 1 along the plug-in direction, the first fool-proofing zone 13 is biased towards being close to the mating surface, and the second fool-proofing zone 14 is biased towards being away from the mating surface. Among the N / 2 or (N±1) / 2 first fool-proofing parts 12 arranged on the connector housing 1, at least one first fool-proofing part 12 must be located in the second fool-proofing zone 14, or all of the first fool-proofing parts 12 may be located in the second fool-proofing zone 14. With such an arrangement, the first fool-proofing zone 13 located in the front may be provided with fewer fool-proofing setting positions 11 and first fool-proofing parts 12, or the first fool-proofing part 12 may not be provided in the first fool-proofing zone 13, thereby reducing the volume of the connector.

[0045] In one embodiment, see Figure 2 As shown, the connector housing 1 is provided with a plug core 3, the foolproof setting position 11 is located on the outer surface of the connector housing 1, and the foolproof setting position 11 is correspondingly located on the outer side of the plug core 3; the connector housing 1 is provided with a locking spring arm 4, and the foolproof setting position 11 located in the second foolproof area 14 overlaps with the locking spring arm 4 along the axial direction of the connector housing 1. In this embodiment, the rear end of the foolproof setting position 11 located in the second foolproof area 14 is located behind the front end of the locking spring arm 4, and the front end of the foolproof setting position 11 located in the second foolproof area 14 is located in front of the front end of the locking spring arm 4 or is flush with the front end of the locking spring arm 4, so that the foolproof setting position 11 located in the second foolproof area 14 partially overlaps with the locking spring arm 4 in the axial direction, which can shorten the length of the connector housing 1.

[0046] In one embodiment, see Figure 2 As shown, the front end of the first foolproof portion 12 is located behind the front end face of the ferrule 3. In this embodiment, the front end face of the ferrule 3 is set to protrude from the front end of the first foolproof portion 12, which can prevent the first foolproof portion 12 from blocking the front end face of the ferrule 3 when grinding the ferrule 3.

[0047] Further, in one embodiment, see Figure 2and Figure 3 As shown, the first foolproofing portion 12 protrudes from the surface of the connector housing 1. In this embodiment, the first foolproofing portion 12 protrudes from the outer surface of the connector housing 1, and correspondingly, the second foolproofing portion 64 that cooperates with the first foolproofing portion 12 of the connector housing 1 to prevent foolishness is set to be recessed.

[0048] In one embodiment, see Figure 3 As shown, the distance between the outer edge of the first foolproof portion 12 located in the first foolproof zone 13 and the axis of the connector housing 1 is defined as a first distance L1; the distance between the inner edge of the first foolproof portion 12 located in the second foolproof zone 14 and the axis of the connector housing 1 is defined as a second distance L2, and the second distance L2 is greater than or equal to the first distance L1. In this embodiment, the outer edge of the first foolproof portion 12 located in the first foolproof zone 13 is on the inner side of the inner edge of the first foolproof portion 12 in the second foolproof zone 14, so that the first foolproof portion 12 in the first foolproof zone 13 and the first foolproof portion 12 in the second foolproof zone 14 are completely offset in the radial direction.

[0049] In one embodiment, see Figure 2 As shown, the connector housing 1 is further provided with an outer sealing ring 5, and the outer sealing ring 5 is located between the first foolproof area 13 and the second foolproof area 14. In this embodiment, by providing the outer sealing ring 5 between the first foolproof area 13 and the second foolproof area 14, the connector housing 1 can be sealed after being docked with a docking piece (such as a female connector or an adapter).

[0050] See also Figure 1 As shown, in some embodiments, among the N foolproof setting positions 11 planned above, m foolproof setting positions 11 are located in the first foolproof area 13, 2m foolproof setting positions 11 are located in the second foolproof area 14, m is a positive integer greater than or equal to 1, and 3m is less than or equal to N. In this embodiment, taking m=2 as an example, 2 foolproof setting positions 11 are planned in the first foolproof area 13, and 4 foolproof setting positions 11 are planned in the second foolproof area 14, a total of 6 foolproof setting positions 11 are planned, and when the first foolproof portion 12 is set on each connector housing 1, it is selected from these 6 foolproof setting positions 11; or, m can also be equal to 3, then 3 foolproof setting positions 11 are planned in the first foolproof area 13, and 6 foolproof setting positions 11 are planned in the second foolproof area 14, a total of 9 foolproof setting positions 11 are planned, and when the first foolproof portion 12 is set on each connector housing 1, it is selected from these 9 foolproof setting positions 11. In this embodiment, 3m can be equal to N or less than N, that is, the fool-proof setting position 11 can be planned only in the first fool-proof area 13 and the second fool-proof area 14, and the fool-proof setting position 11 can also be planned in other areas of the connector housing 1 except these two areas.

[0051] Further, in one embodiment, N / 2 or (N±1) / 2 of the first fool-proofing parts 12 provided on the connector housing 1 are all located in the second fool-proofing zone 14; or, among the N / 2 or (N±1) / 2 first fool-proofing parts 12 provided on the connector housing 1, n of the first fool-proofing parts 12 are located in the first fool-proofing zone 13, and 2n of the first fool-proofing parts 12 are located in the second fool-proofing zone 14, where n is a positive integer greater than or equal to 1; or, among the N / 2 or (N±1) / 2 first fool-proofing parts 12 provided on the connector housing 1, 2n of the first fool-proofing parts 12 are located in the first fool-proofing zone 13, and n of the first fool-proofing parts 12 are located in the second fool-proofing zone 14, where n is a positive integer greater than or equal to 1.

[0052] Through the analysis of the automobile industry, current vehicles generally require 20 foolproofing methods, corresponding to 20 different connectors, so that the correct connector can be inserted into the correct adapter. In this embodiment, when 2 foolproofing setting positions 11 are planned in the first foolproofing area 13, and 4 foolproofing setting positions 11 are planned in the second foolproofing area 14 (that is, N is 6), the 6 foolproofing setting positions 11 can be arranged and combined into 20 combinations. The first selection method is: do not take the foolproofing setting position 11 in the first foolproofing area 13, and take 3 foolproofing setting positions 11 in the second foolproofing area 14. This selection method can obtain 4 combinations; the second selection method is: take 1 foolproofing setting position 11 in the first foolproofing area 13, and take 2 foolproofing setting positions 11 in the second foolproofing area 14. This selection method can obtain 12 combinations; the third selection method is: take 2 first foolproofing setting positions 11. The fool-proof setting position 11 in the zone 13, and the fool-proof setting position 11 of the second fool-proof zone 14, this selection method can also obtain 4 combinations; these three selection methods can obtain a total of 20 different combinations, and the first fool-proof part 12 is set at the fool-proof setting position 11 in these 20 combinations, and is applied to different connector housings 1 respectively, so a total of 20 different connectors can be obtained, and the position of the first fool-proof part 12 on each connector is different, which can distinguish a large number of connectors one by one, and a second fool-proof part 64 that is compatible with the position and structure of the first fool-proof part 12 is set on the corresponding docking connector, which can avoid many connectors from being plugged in incorrectly with the docking connector.

[0053] Further, in one embodiment, see Figure 1 As shown, the planned N fool-proof setting positions 11 are symmetrically distributed on opposite sides of the connector housing 1 about the axis of the connector housing 1 . Figure 1The figure shows the planned 6 fool-proof setting positions 11. The two fool-proof setting positions 11 of the first fool-proof area 13 are located on the plane where the axis of the connector housing 1 is located. Among the 4 fool-proof setting positions 11 of the second fool-proof area 14, two fool-proof setting positions 11 are distributed on the left side of the connector housing 1, and the other two fool-proof setting positions 11 are distributed on the right side of the connector housing 1, and the fool-proof setting positions 11 on the left and right sides are symmetrically arranged.

[0054] Preferably, see Figure 1 and Figure 3 As shown, among the planned N foolproofing positions 11, the two first foolproofing parts 12 arranged in the first foolproofing area 13 have the same structure, and the cross section of each first foolproofing part 12 is roughly rectangular; the four first foolproofing parts 12 arranged in the second foolproofing area 14 also have basically the same structure, and the cross section of each first foolproofing part 12 is roughly triangular. The foolproofing position 11 corresponding to the place where the first foolproofing part 12 is not arranged on each connector housing 1 is empty (see Figure 2 and Figure 3 shown).

[0055] In some embodiments, see Figure 2 As shown, the connector housing 1 may also be provided with an identification color and / or identification label 2. In this embodiment, different connectors may set the connector housing 1 to different colors, such as the A-pillar camera connector uses red, the B-pillar camera connector uses green, etc.; at the same time, the adapter (or female connector) to be connected uses the same color. By setting matching colors, the selection range of the connector can be narrowed down visually. At the same time, an identification label 2 (such as a serial number) may also be set on the connector. The identification label 2 on the connector needs to correspond one-to-one with the identification label 2 on the adapter. In this way, the paired connector can also be selected visually, such as putting a label 1 on the A-pillar camera connector, and the adapter (female connector) to be connected uses the same label. In this embodiment, by setting an identification color and / or identification label 2 on the connector, the color and / or label can be used to filter the connector first. The color and / or label ensure the efficiency of insertion, and then different first foolproofing parts 12 are set on different connectors to achieve different foolproofing effects, ensuring a one-to-one correspondence between the connector and the adapter, and fully ensuring correct insertion.

[0056] See also Figure 4 and Figure 5As shown, the embodiment of the present application further provides a female connector, which includes: a connector body 6, wherein the connector body 6 is provided with a second foolproof portion 64 that cooperates with the first foolproof portion 12 of the connector, and the number of the second foolproof portion 64 is equal to that of the first foolproof portion 12 and the positions are corresponding. The connector provided with the first foolproof portion 12 in this embodiment can adopt the connector provided in any of the above embodiments and realize the corresponding functions, which will not be repeated here.

Of course, the female connector can also adopt the above-mentioned connector, and the number and position of the second foolproof portion 64 in the female connector correspond to the first foolproof portion 12 in the male connector, and the structures are complementary, for example, when one is a slot, the other is a key.

[0059] The embodiment of the present application also provides a connector combination, which may include: a plurality of male connectors and a plurality of female connectors that are paired one by one, each of the male connectors having N fool-proofing setting positions 11 at different positions, and any N / 2 or (N±1) / 2 of the N fool-proofing setting positions 11 are arbitrarily selected to be provided with a first fool-proofing portion 12, the position of at least one of the first fool-proofing portions 12 on different male connectors is different, and the female connector paired with the male connector is provided with a second fool-proofing portion 64 corresponding to the position and number of the first fool-proofing portion 12 on the male connector; wherein N is a positive integer greater than or equal to 1, and when N is an even number, the male connector is provided with N / 2 of the first fool-proofing portions 12; and when N is an odd number, the male connector is provided with (N±1) / 2 of the first fool-proofing portions 12.

[0060] The male connector in this embodiment can adopt the connector provided in any of the above embodiments and realize the corresponding functions.

[0061] For example, the connector combination of this embodiment may include 20 male connectors and 20 female connectors, and the 20 male connectors are paired one to one with the 20 female connectors. Here, N can be 6, and three first anti-mistake parts 12 are set on each male connector, and the first anti-mistake parts 12 on each male connector are not exactly the same, so that each male connector can be inserted into a unique female connector.

[0062] The design method of the above connector provided in the embodiment of the present application is as follows:

[0063] Step 1: Plan N fool-proofing setting positions 11 with different positions on the connector housing 1, where N is a positive integer greater than or equal to 1.

[0064] Step 2: Randomly select N / 2 or (N±1) / 2 of the N fool-proofing setting positions 11 of the connector housing 1 to set the first fool-proofing part 12; when N is an even number, set N / 2 of the first fool-proofing parts 12; when N is an odd number, set (N±1) / 2 of the first fool-proofing parts 12.

[0065] In this embodiment, in order to completely prevent the connector and the adapter from being inserted incorrectly and to minimize the number of the first foolproofing parts 12, it is necessary to plan the number and position of the foolproofing setting positions 11 at the beginning of the design. In this embodiment, N foolproofing setting positions 11 are planned on the connector, and N foolproofing setting positions 11 are also planned on the adapter. The foolproofing setting positions 11 on the adapter correspond one to one with the foolproofing setting positions 11 on the connector. When designing different connectors, each connector housing 1 selects N / 2 or (N±1) / 2 of the foolproofing setting positions 11 from the N foolproofing setting positions 11 to set the first foolproofing part 12, and the foolproofing setting positions 11 selected by different connectors are not exactly the same, so that the position of the first foolproofing part 12 set on each connector housing 1 is not exactly the same, thereby distinguishing multiple connectors one by one.
