Furthermore, the terms "first" and "second" serve only for the purpose of differentiation in the description and have no special meaning.

[0022] In one embodiment of the present utility model, a connector and a connector assembly are proposed, wherein the connector assembly comprises the connector and a docking connector for interacting with the connector by insertion, the connector being connected to a device via a cable and the docking connector being arranged on a device body of another device. The device on which the docking connector is located may (but is not) be an on-board processing device such as a domain controller or IVI, and the connector may (but is not) be an on-board device such as a laser radar or a gateway.

[0023] With reference to Fig. 3 The connector comprises an insulating body 1, a first terminal 3, a first sealing ring 8, a second sealing ring 9 and a first locking element 5, wherein the insulating body 1 is provided with first mounting holes 12 extending in the same direction, and each of the first mounting holes 12 has a first opening 121 and a second opening 122 arranged opposite each other, wherein several first terminals 3 are detachably inserted into the first mounting hole 12 from their respective first openings 121 and are uniquely assigned to each other, and the first docking terminals of the docking connector adapted to the first terminals 3 can be electrically connected to the first terminals 3 through the second openings 122, wherein each first terminal 3 is connected to a first cable 20, the first cable 20 emerging from the insulating body 1 through the first opening 121.wherein the first sealing ring 8 is attached to and abuts the insulating body 1 on one of the sides facing the first hole opening 121, wherein the first sealing ring 8 is provided with several through holes 84 which are uniquely assigned to the several first cables 20, wherein the first cable 20 is inserted into the through hole 84 and abuts the inner wall of the through hole 84, wherein the second sealing ring 9 is placed on the outside of the insulating body 1 and the housing of the docking connector can be placed on the insulating body 1 and abut the second sealing ring 9, wherein a first locking element 5 is detachably inserted into the insulating body 1, wherein the first locking element 5 is provided with escape grooves 513, the number of which corresponds to that of the first connections 3, and wherein the first locking element 5 has a pre-installed position and a final locking position,wherein the offset groove 513 on the first locking element 5 is located opposite each first connection in the pre-installation position to allow the insertion of the first connection 3 into the first mounting hole 12 or its withdrawal from the first mounting hole 12; wherein the offset groove 513 on the first locking element 5 is offset from each first connection 3 in the final locking position to lock multiple first connections 3 simultaneously.

[0024] The connector and connector assembly use the first locking element 5 to lock several first terminals 3 simultaneously, thereby simplifying the structure of the connector and connector assembly, reducing the assembly difficulties of the connector and connector assembly, and wherein the first locking element 5 can be pre-mounted on the insulating body 1 with a pre-installed position and a final locking position when the first terminals 3 are not inserted into the insulating body 1, in order to prevent the first locking element 5 from being lost;Simultaneously, the first sealing ring 8 serves to seal the first cable 20 and the insulating body 1, and the second sealing ring 9 serves to seal the connector and the docking connector, thereby improving the sealing performance of the entire connector assembly and achieving good dust and water resistance, and wherein the first sealing ring 8 can seal several first connections 3 and the insulating body 1 simultaneously, further simplifying the assembly effort of the connector and the connector assembly.

[0025] With reference to Fig. 12 On the side of the insulating body 1 facing one of the first hole openings 121, a mounting groove 110 is provided, which is connected to each of the first mounting holes 12, wherein the first sealing ring 8 is embedded in the receiving groove 110 and rests against the groove wall of the receiving groove 110, whereby the provision of the mounting groove 110 improves the stability of the connection between the first sealing ring 8 and the insulating body 1.

[0026] With reference to Fig. 24 The first sealing ring 8 has, to improve its sealing performance, a sealing body 83 and several first annular projections 81, which are spaced apart on the outer wall surface of the sealing body 83 along the longitudinal direction of the first mounting hole 12 to increase the contact area with the groove side wall of the mounting groove 110 and improve the sealing performance. Simultaneously, several second annular projections 82 are arranged at intervals along the longitudinal direction of the through-hole 84 on the hole wall of each through-hole 84 to increase the contact area with the second cable 10 and improve the sealing performance. In the present embodiment, the longitudinal direction of the through-hole 84 coincides with the longitudinal direction of the first mounting hole 12 to reduce the bending deformation of the second cable 10.

[0027] With reference to Fig. 25 Several third annular projections 91 and several fourth annular projections 92 are arranged at intervals on the inner circumferential wall and the outer circumferential wall of the second sealing ring 9 along the longitudinal direction of the first mounting hole 12 in order to increase the contact area between the second sealing ring 9 and the insulating body 1 and the docking connector, thereby improving the sealing performance.

[0028] With reference to Fig. 1, Fig. 2 to Fig. 3 The connector also includes a second terminal 2 and a second locking element 4. The insulating body 1 is also provided with a second mounting hole 11, wherein the second terminal 2 is detachably inserted into the second mounting hole 11, wherein the second mounting hole 11 is provided with a second snap element 13, and the first mounting hole 12 is provided with a first snap element 14, wherein the second snap element 13 is used to fix the second terminal 2 at a preset position of the second mounting hole 11, and wherein the first snap element 14 is used to fix the first terminal 3 at a preset position of the first mounting hole 12.The second locking element 4 is also detachably inserted into the insulating body 1 and has a pre-installed position and a final locking position, and the second locking element 4 in the pre-installed position allows the second connection 2 to be inserted into the second mounting hole 11, and the second locking element 4 in the final locking position allows the second snap element 13 to continue to lock the second connection 2.

[0029] The connector uses the second snap element 13 to lock the second terminal 2 once, and then uses the second locking element 4 to limit the second snap element 13 so that the second snap element 13 continues to lock the second terminal 2, thereby improving the stability of the connection between the second terminal 2 and the insulating body 1; the first snap element 14 locks the first terminal 3 once, and the first locking element 5 locks the first terminal 3 twice, thereby improving the connection stability between the first terminal 3 and the insulating body 1, thus improving the assembly stability of the entire connector.

[0030] In the present embodiment, the second terminal 2 is connected to the second cable 10, and the second terminal 2 and the first terminal 3 have different functions. For example, the second terminal 2 is a signal terminal for transmitting Ethernet signals, and the second cable 10 connected to the second terminal 2 is a high-speed signal cable. The first terminal 3 is a low-voltage terminal for transmitting, for example, a slow CAN signal, and the first cable 20 connected to the first terminal 3 is a low-voltage cable. To accommodate the second terminal 2 and the first terminal 3, the internal dimensions of the second mounting hole 11 and the first mounting hole 12 are different, with the internal dimension of the second mounting hole 11 being larger than the internal dimension of the first mounting hole 12.

[0031] It is understandable that, in order to achieve a seal between the second connection 2 and the insulating body 1, a sealing element that rests against the insulating body 1 can also be placed on the second connection 2, which is not described in more detail here.

[0032] With reference to Fig. 1 and Fig. 2. The second mounting hole 11 and the first mounting hole 12 both extend along the first direction (the X-direction and its reverse direction in). Fig. 1, where the X-direction is the positive direction of the first direction and the inverse direction of the X-direction is the inverse direction of the first direction), and the second mounting hole 11 and the first mounting hole 12 are along a third direction (Z-direction and its inverse direction in Fig. 1, where the Z-direction is the positive direction of the third direction and the reverse direction of the Z-direction is the reverse direction of the third direction) are spaced apart perpendicular to the first direction. To make the mounting of the second locking element 4 and the first locking element 5 on the insulating body 1 more difficult, and due to the limited size of the interior of the second mounting hole 11 and the first mounting hole 12, the second locking element 4 moves along the first direction to achieve the change between the pre-installed position and the final locking position, with the first locking element 5 moving along the third direction to achieve the change between the pre-installed position and the final locking position.

[0033] For example, the number of second mounting holes is 11, while the number of first mounting holes is 12, and the six first mounting holes 12 are along the second direction (the Y-direction in Fig. 1 and the inverse direction thereof, wherein the Y-direction is the positive direction of the second direction and the inverse direction of the Y-direction is the inverse direction of the second direction) are arranged in two symmetrically provided rows, and the first mounting holes 12 in each row comprise three first mounting holes 12 spaced apart along the third direction, wherein the number of first connections 3 is equal to the number of first mounting holes 12, which is also 6. At this point, the first locking element 5, moving along the third direction, can lock several first connections 3 simultaneously, wherein the second direction is perpendicular to the first direction and to the third direction.

[0034] With reference to Fig. 5 to Fig. In section 7, it is provided that the second mounting hole 11 has a third hole opening 111 and a fourth hole opening 112, which are arranged opposite each other along the first direction, and wherein the third hole opening 111 is arranged on one side of the fourth hole opening 112 along the positive direction of the first direction, wherein the second connection 2 can be inserted from the third hole opening 111 into the second mounting hole 11 and moved in the direction of the fourth hole opening 112.The second docking port of the docking connector, adapted to the second port 2, can be electrically connected to the second port 2 via the fourth hole opening 112, wherein a first stop surface 151 is arranged on one side of the inner wall of the second mounting hole 11 facing the fourth hole opening 112, wherein the first stop surface 151 can rest against the first contact surface 211 on the second port 2, thereby preventing the second port 2 from moving further towards the fourth hole opening 112, so that the second port 2 is inserted into the preset position of the second mounting hole 11.

[0035] Specifically with reference to Fig. 5 and Fig. In section 12, it is provided that two first limit stops 15, which are opposite each other, are arranged on the inner wall surface of the second mounting hole 11 in a second direction, wherein the first stop surface 151 is formed on the inner surface of the first limit stop 15 and is arranged such that the first stop surface gradually moves away from the hole wall of the second mounting hole 11, from an end facing the third hole opening 111 to an end facing away from the third hole opening 111. The first contact surface 211 is also provided inclined accordingly.

[0036] With reference to Fig. 6 and Fig. In section 7, the outer wall surface of the second connection 2 is provided with a first recess 221, wherein the second snap element 13 comprises a first elastic arm 131 and a first clamping block 132, which are integrally formed, wherein one end of the first elastic arm 131 facing the third hole opening 111 is connected to the hole wall of the second mounting hole 11 and the other end gradually moves away from the hole wall of the second mounting hole 11 towards the fourth hole opening 112, wherein the first clamping block 132 is arranged on a side of the first elastic arm 131 facing away from the hole wall of the second mounting hole 11, wherein the first clamping block 132 engages with the first recess 221 by snapping into place.

[0037] After the second connector 2 has been inserted from the third hole opening 111 into the second mounting hole 11, it can press the second snap element 13, causing the first elastic arm 131 to deform and drive the first clamping block 132 towards the hole wall of the second mounting hole 11 until the first clamping block 132 is engaged in the first recess 221. At this point, the first stop surface 151 rests against the first contact surface 211, and the second snap element 13 locks the second connector 2 to prevent it from moving towards the third hole opening 111.

[0038] Specifically, two second snap elements 13 are arranged symmetrically in the second mounting hole 11 along the third direction to improve the locking stability of the second snap elements 13 at the second connection 2. More specifically, the two second snap elements 13 are each arranged in two columns formed by the two first limit stops 15 and connected to the first limit stops 15 to improve the structural strength of the second snap elements 13.

[0039] More specifically, a first guide surface is arranged on one side of the first terminal block 132 facing the third hole opening 111, the first guide surface gradually moving away from the hole wall of the second mounting hole 11, from one side facing the third hole opening 111 to one side facing away from the third hole opening 111, in order to reduce the difficulty of the end of the second terminal 2 inserted into the second mounting hole 11 running over the first terminal block 132 when moving towards the fourth hole opening 112.

[0040] In order to make it more difficult to insert the second terminal 2 into the second mounting hole 11 in the present embodiment, the area of ​​the third hole opening 111 is larger than the maximum cross-sectional area of ​​the second terminal 2. Based on this, the connector further comprises an end cover 30, which is mounted on the insulating body 1 and is located on one side of the third hole opening 111 of the second mounting hole 11, the end cover 30 being provided with a threading hole for passing the first cable 20 through, and the area of ​​the threading hole being smaller than the area of ​​the third hole opening 111.

[0041] After the second terminal 2, connected to the second cable 10, has been inserted into the second mounting hole 11, the end cover 30 is mounted on the insulating body 1. This reduces the possibility of the second cable 10 wobbling and improves the stability of the entire connector. Specifically, the end cover 30 is connected to the insulating body 1 by a snap-fit ​​connection to facilitate inspection and replacement of the second terminal 2.

[0042] As in Fig. As shown in Figure 15, the second terminal 2 comprises a front shielding shell 21, an inner conductor, a wire clamp and a rear shielding shell 22, wherein the rear end of the front shielding shell 21 is placed on the rear shielding shell 22 and crimped to the rear shielding shell 22, the inner conductor being located in the front shielding shell 21 to electrically connect the second docking terminal to the second cable 10, and the wire clamp being located in the rear shielding shell 22 to fix one end of the second cable 10 in the rear shielding shell 22.The front shielding shell 21 is provided in reverse order to the first direction with a small-diameter section and a large-diameter section, wherein the first contact surface 211 is formed between the large-diameter section and the small-diameter section, and the rear shielding shell 22 is dumbbell-shaped, wherein the first recess 221 is an annular groove formed on the rear shielding shell 22, and the annular groove is located outside the front shielding shell 21.

[0043] It is understandable that in other embodiments the first recess 221 may be arranged on the first elastic arm 131, while the first clamping block 132 is arranged on the second connection 2.

[0044] To prevent the second terminal 2 from being inserted too deeply into the second mounting hole 11 and thereby damaging the second terminal 2 or the insulating body 1, it is necessary, with reference to Fig. 12 and Fig. In the present embodiment, the inner surface of the first limit stop 15 is also provided with a guide groove 152 extending along the first direction, and the guide groove 152 is closed on one side facing the fourth hole opening 112. The outer wall surface of the second connection 2 is provided with a guide block 212 that slidably fits with the guide groove 152. When the second connection 2 is in the preset position in the second mounting hole 11, the guide block 212 rests against the groove wall at one end of the guide groove 152 facing the fourth hole opening 112. Specifically, the guide block 212 is arranged on the outer wall surface of the large-diameter section.

[0045] With reference to Fig. In paragraph 14, the first locking element 4 comprises a mounting section 41 and a plug section 42, wherein the mounting section 41 is connected to the plug section 42 and is located outside the plug section 42, wherein a clamping space with a hole opening to the third hole opening 111 is formed between the mounting section 41 and the plug section 42, wherein the plug section 42 is inserted from the fourth hole opening 112 into the second mounting hole 11, wherein the mounting section 41 is placed on the outside of the insulating body 1, so that the side wall of the insulating body 1 is clamped in the clamping space.

[0046] The second locking element 4 is inserted from the fourth hole opening 112 into the second mounting hole 11. As shown in Fig. 6 and Fig. As shown in Figure 7, the second locking element 4 and the second snap element 13 are spaced apart in the first direction when the second locking element 4 is in a pre-installed position, the second locking element 4 not hindering the deformation of the second snap element 13 so that the second terminal 2 can be inserted from the third hole opening 111 into the pre-set position of the second mounting hole 11; when the second locking element 4 is in the final locking position, the second snap element 13 moves along the first direction towards the second terminal 2, and the inside of the connector section 42 is against the side of the second snap element 13 facing away from the second terminal 2.Limited by the plug section 42, the second snap element 13 can no longer deform towards the perforated wall of the second mounting hole 11 and is always firmly locked onto the second terminal 2, thus maintaining the stability of the second terminal 2 when inserted into the second mounting hole 11. It should be emphasized that the end face of the insulating body 1 rests against the side of the terminal space facing away from the opening when the second locking element 4 is in its final locking position, thereby preventing any further movement of the second locking element 4 towards the third hole opening 111.

[0047] Specifically, a stepped surface 421 is formed at one end of the plug section 42, which is inserted into the second mounting hole 11. When the second locking element 4 is in its final locking position, the second snap element 13 rests against the stepped surface 421 to fix the final locking position of the second locking element 4, thus further reducing the possibility of the second locking element 4 being inserted too far into the second mounting hole 11.

[0048] Simultaneously, a second stop surface 422 is also provided on the side of the second locking element 4 facing the second connection 2. This second stop surface 422 gradually moves away from the wall of the second mounting hole 11, from an end facing the third hole opening 111 to an end facing away from the third hole opening 111. A second bearing surface 213, which aligns with the second stop surface 422, is formed on the outer wall surface of the second connection 2. When the second locking element 4 is in its final locking position, the second stop surface 422 rests against the second bearing surface 213 and interacts with the first stop surface 151 and the first bearing surface 211 to further restrict the movement of the second connection 2 towards the fourth hole opening 112.

[0049] More specifically, two second stop surfaces 422 are arranged opposite each other on the inner wall of the second locking element 4. Accordingly, two second contact surfaces 213 are also provided, and the two second contact surfaces 213 are also formed between the small-diameter section and the large-diameter section of the front shielding shell 21, i.e., the second contact surface 213 and the first contact surface 211 together form a conical surface that connects the large-diameter section and the small-diameter section.

[0050] With reference to Fig. 5 and Fig. 9. To facilitate observation of whether the second locking element 4 is in the pre-installed position or the final locking position, and to improve the stability of the second locking element 4 after assembly on the insulating body 1, one of the elements, namely the second locking element 4 and the insulating body 1, is also provided with a first positioning block 17, while the other is provided with a first groove opening 43 which engages with the first positioning block 17 by snapping, wherein there are two first groove openings 43 spaced apart from each other along the first direction, wherein when the first positioning block 17 is restricted to one of the groove openings of the two first groove openings 43 facing away from the fourth hole opening 112, the second locking element 4 is in the pre-installed position, wherein,If the first positioning block 17 is restricted to one of the groove openings 43 facing the fourth hole opening 112, the second locking element 4 is in the final locking position.

[0051] For example, the first positioning block 17 is located on the insulating body 1 and the first groove opening 43 is located on the second locking element 4. Specifically, the cross-section of the first positioning block 17 is designed as an equilateral trapezoid or equilateral triangle with chamfered corners to make it more difficult to insert and remove the first positioning block 17 from the first groove opening 43.

[0052] Referring to Fig. 14 To reduce the difficulty of separating the second locking element 4 from the insulating body 1, a release recess 411 is formed on the mounting section 41, the release recess 411 extending along the first direction to an end face of the mounting section 41 facing the second connection 2. When the second locking element 4 is removed, a force is exerted on the mounting section 41 in the second direction away from the insulating body 1, so that the first positioning block 17 can be separated from the first groove opening 43.

[0053] With reference to Fig. 8 The first mounting holes 12 each have a first hole opening 121 and a second hole opening 122, which are arranged opposite each other in the first direction, wherein the first hole opening 121 and the third hole opening 111 are located on the same side of the insulating body 1, and a third stop surface 161 is arranged on one side of the first mounting hole 12 facing the second hole opening 122, wherein the third stop surface 161 can abut the third contact surface 33 on the first terminal 3, thereby preventing the first terminal 3 from moving further towards the second hole opening 122, so that the first terminal 3 is inserted into the preset position of the first mounting hole 12.

[0054] Specifically, a second annular limit stop 16 is provided on one side of the first mounting hole 12 facing the second hole opening 122, wherein the third stop surface 161 is formed on one side of the second limit stop 16 facing away from the second hole opening 122 and is designed as a conical surface that gradually widens from one end facing the second hole opening 122 to one end facing away from the second hole opening 122, wherein a conical third contact surface 33 is formed on the outer wall surface of the first connection 3, wherein when the third contact surface 33 abuts the third stop surface 161, the first connection 3 is inserted into the preset position of the first mounting hole 12.

[0055] With reference to Fig. 8 and Fig. In section 17, a second recess 31 is provided on the outer wall surface of the first connection 3, wherein the first snap element 14 comprises a second elastic arm 141 and a second clamping block 142, which are formed in one piece, wherein one end of the second elastic arm 141 facing the first hole opening 121 is connected to the hole wall of the first mounting hole 12 and the other end gradually moves away from the hole wall of the first mounting hole 12 towards the second hole opening 122, wherein the second clamping block 142 is arranged on a side of the second elastic arm 141 facing away from the hole wall of the first mounting hole 12, and wherein the second clamping block 142 engages with the second recess 31 by snapping into place. Specifically, the second recess 31 is a groove provided on the outer wall surface of the first connection 3.

[0056] After the first connector 3 has been inserted from the first hole opening 121 into the first mounting hole 12, it can press the first snap element 14, whereby the second elastic arm 141 deforms and drives the second clamping block 142 towards the hole wall of the first mounting hole 12 until the second clamping block 142 is engaged in the second recess 31, at which time the third stop surface 161 rests against the third contact surface 33, and the first connector 3 is locked by the interaction with the first snap element 14.

[0057] In the present embodiment, it is provided that a second guide surface is also provided on one side of the second terminal block 142 facing the first hole opening 121, wherein the second guide surface gradually inclines from one side facing the first hole opening 121 towards the center of the first mounting hole 12 in order to reduce the difficulty of the end of the first connection 3 inserted into the first mounting hole 12 passing over the second terminal block 142 when the end moves towards the second hole opening 122.

[0058] It is understood that the positions of the second recess 31 and the second clamping block 142 between the second elastic arm 141 and the first connection 3 can be interchanged.

[0059] The first locking element 5 is inserted into the insulating body 1 from a side facing away from the second connection 2 in the opposite direction to the third direction. As shown in the Fig. 10, Fig. 11 and Fig. As shown in Figure 16, the escape groove 513 penetrates the first locking element 5 along the first direction, and the multiple escape grooves 513 are arranged at intervals along the third direction.

[0060] To prevent the first locking element 5 from being deflected during its movement along the third direction, a release groove 32 is provided at the first terminal 3, and the multiple release grooves 32 at each first terminal 3 are arranged along the third direction.

[0061] Let us assume the example that two rows of first terminals 3 are arranged symmetrically along the second direction, with reference to Fig. 16 further, the first locking element 5 comprises a connecting section 52 and two cantilever sections 51, the two cantilever sections 51 are each arranged on two sides opposite each other along the second direction of the connecting section 52 and are perpendicular to the connecting section 52, so that the first locking element 5 is approximately U-shaped.The deflection grooves 513 are arranged on the cantilever sections 51, and wherein, when the cantilever sections 51 are inserted into the insulating body 1 until the first terminal 3 is in the pre-installed position, the respective deflection grooves 513 on the cantilever sections 51 are each assigned to the respective first terminals 3 and do not interfere with the insertion of the first terminal 3 into the first mounting hole 12 or with its disconnection, wherein, when the cantilever sections 51 are further inserted into the insulating body 1 until the first terminal 3 is in the final locking position, the respective deflection groove 513 is offset from the respective first terminal 3 to prevent the first terminal 3 from moving towards the second hole opening 122.

[0062] With reference to Fig. 13 Two fastening grooves 18 extending along the third direction are provided on the outer wall of the insulating body 1 to guide the first connection 3 when inserting the first connection 3 into the insulating body 1, the two fastening grooves 18 each being connected to the two rows of first mounting holes 12, and the two cantilever sections 51 are each inserted into the insulating body 1 along the two fastening grooves 18.

[0063] Furthermore, to make it easier to determine whether the first locking element 5 is in the pre-installed position or in the final locking position, and to improve the stability of the first locking element 5 during assembly on the insulating body 1, one of the elements, namely the first locking element 5 and the insulating body 1, is also provided with a second positioning block 514, while the other is provided with a second groove opening 19 which engages with the second positioning block 514 by snapping into place, wherein two second groove openings 19 are arranged at intervals along the insertion direction of the first locking element 5 into the insulating body 1, wherein when the second positioning block 514 is restricted to a groove opening of the two second groove openings 19 facing away from the second terminal 2, the first locking element 5 is in the pre-installed position, wherein,If the second positioning block 514 is restricted to a slot opening of the two second slot openings 19 facing the second terminal 2, the first locking element 5 is in the final locking position.

[0064] For example, the second positioning block 514 is arranged on the cantilever section 51 of the first locking element 5, wherein the two cantilever sections 51 are each provided with a second positioning block 514, and the second groove openings 19 corresponding to the second positioning blocks 514 are each provided on the groove side walls of the two fastening grooves 18.

[0065] To facilitate the insertion of the second positioning block 514 into the second groove opening 19, the second positioning block 514 is designed in a triangular shape, wherein the first locking element 5 is also provided with a strip-shaped release hole 515 extending along the third direction, wherein, when the second positioning block 514 enters the second groove opening 19, the release hole 515 provides a clearance for the deformation of the first locking element 5.Specifically, the cantilever section 51 further comprises an L-shaped mounting section 512 and a locking section 511, wherein the mounting section 512 and the locking section 511 are both connected to the connecting section 52, the mounting section 512 being able to slide in the mounting groove 18 and the locking section 511 being inserted into the first mounting hole 12, the second positioning block 514 and the clearance groove 513 being arranged on the mounting section 512 and the locking section 511 respectively, and the release hole 515 also being arranged on the mounting section 512. It is understood that the provision of the release hole 515 reduces the material costs for manufacturing the first locking element 5.

[0066] To more specifically reduce the difficulty of disassembling the first locking element 5, a force application groove 521 is also provided on the connecting section 52 for convenient force application.

[0067] With reference to Fig. 3 and Fig. The connector further comprises a first sealing ring 8, wherein the first sealing ring 8 is arranged at the second hole opening 122 of the first mounting hole 12 and is provided with a through hole 84 for the passage of the second cable 10, wherein the first sealing ring 8 can seal the gap between the second hole opening 122 and the first connection 3 to achieve a dustproof and watertight effect.

[0068] With reference to Fig. 1, Fig. 2 to Fig. 3. The connector further comprises a housing 6 that is firmly fitted around the outside of the insulating body 1 to protect the insulating body 1, and a gap is provided between the housing 6 and the insulating body 1 for inserting the docking connector. More specifically, the housing 6 has an interior with an open side along the side opposite the first direction, and the insulating body 1 is located inside the housing 6. An actuating hole 61 is provided at a position corresponding to the connection section 52 of the first locking element 5 on the housing 6. This actuating hole 61 connects to the interior of the housing 6, and a force can be applied through the actuating hole 61 to the first locking element 5 in the direction of the second terminal 2, thus moving the first locking element 5 from its pre-installed position to its final locking position.

[0069] It should be emphasized that the length of the actuating hole 61 along the second direction is smaller than the length of the connecting section 52 along the second direction. In other words, the orthographic projection area of ​​the first locking element 5 in the direction of the actuating hole 61 is larger than the area of ​​the actuating hole 61, which is intended to prevent the first locking element 5 from detaching from the insulating body 1 during transport out of the actuating hole 61 or from being forced into the final locking position.

[0070] Specifically with reference to Fig. 9, Fig. 22 and Fig. 23 The housing 6 is provided with a third groove opening 62, and the insulating body 1 is provided with a third positioning block 120, which can interact with the third groove opening 62 by snapping into place, the third positioning block 120 being confined within the third groove opening 62 to achieve a releasable fixed connection between the insulating body 1 and the housing 6. More specifically, two third groove openings 62 are arranged symmetrically along the third direction on the housing 6, with two third positioning blocks 120 being provided to improve the stability of the connection between the housing 6 and the insulating body 1, and with an inclined third guide surface being formed at an end of the third positioning block 120 facing away from the notch of the housing 6 to make it more difficult for the third positioning block 120 to snap into the third groove opening 62.Of course, the third groove opening 62 can also be provided on the insulating body 1, while the third positioning block 120 is provided on the housing 6.

[0071] With reference to Fig. 16 the third hole opening 111 and the first hole opening 121 on the insulating body 1 both directed towards a closed end of the housing 6, and wherein the closed end of the housing 6 is provided at positions corresponding to the second mounting hole 11 and the first mounting hole 12 with several through-holes 63 through which the first cable 20 and the second cable 10 can be passed, and the docking connector can be electrically connected to the plug from the open end of the housing 6.

[0072] A gap for inserting the docking connector is provided between the end of the insulating body 1 facing the opening of the housing 6 and the housing 6. To lock the docking connector to the connector, the housing 6 also has a third snap element 64, which is arranged on the inner wall of the housing 6, and which engages with the connector by snapping into place.

[0073] Specifically with reference to Fig. 19 and Fig. 22 it is provided that the third snap element 64 comprises a third elastic arm 641 and a third recess 643, wherein the third elastic arm 641 is connected to the inner wall of the housing 6, wherein the third recess 643 is arranged at an end extending towards the notch of the third elastic arm 641, wherein a third clamping block is formed on the docking connector which fits the third recess 643, wherein the third clamping block can be clamped into the third recess 643 to lock the docking connector.

[0074] More specifically, two third elastic arms 641 are arranged at intervals along the third direction and the two third elastic arms 641 are connected to each other by a connecting rod 642 to form the third recess 643 between the two third elastic arms 641, with the third clamping block being snapped into the third recess 643 and bearing against the connecting rod 642.

[0075] As in Fig. 19 and Fig. As shown in Figure 23, the closed end of the housing 6 is provided with an insertion hole 65 through which the third snap element 64 extends into the interior of the housing 6. The insertion hole 65 is connected to the interior of the housing 6, with the third elastic arm 641 being connected to the perforated wall of the insertion hole 65 via a support point. One end of the third elastic arm 641, which is connected to the connecting rod 642, extends from the insertion hole 65 into the interior of the housing 6, while the other end is located outside the housing 6. To release the third snap element 64 from the locking mechanism of the docking connector, it is only necessary to press the end of the third elastic arm 641 that is located outside the housing 6.

[0076] To further improve the stability between the connector and the docking connector, the connector also has a third locking element 7, wherein the third locking element 7 also has a pre-installed position and a final locking position, wherein the third locking element 7 in the pre-installed position allows the docking connector to be inserted into a preset position in the housing 6, and the third locking element 7 in the final locking position allows the third snap element 64 to continue to lock the docking connector.

[0077] With further reference to Fig. 19 and Fig. 20 The third locking element 7 is inserted into the housing 6 from the closed end along the first direction, the third locking element 7 having a locking arm 71, and the end of the locking arm 71 of the third locking element 7 in the pre-installed position is located on one side of the connecting rod 642 facing away from the opening of the housing 6, and the locking arm 71 of the third locking element 7 in the final locking position lies on the outside of the third snap element 64, which prevents the third snap element 64 from moving to the side facing away from the third clamping block. More specifically, a locking groove 72 is provided on the locking arm 71, and the connecting rod 642 can be positioned in the locking groove 72 and bear against the bottom of the locking groove 72.

[0078] As in Fig. 21 and Fig. As shown in Figure 23, to improve the stability of the third locking element 7 during assembly on the housing 6, a fourth positioning block 66 is also arranged on one of the two elements, namely the third locking element 7 and the housing 6, and a fourth slot opening 731, which engages with the fourth positioning block 66 by snapping, is arranged on the other element, wherein there are two fourth slot openings 731 spaced apart from each other along the first direction, wherein when the fourth positioning block 66 is snapped into a slot opening of the two fourth slot openings 731 facing away from an open end of the housing 6, the fourth locking element is in the pre-installed position;wherein, when the fourth positioning block 66 is engaged in a slot opening of the two fourth slot openings 731 facing an open end of the housing 6, the fourth locking element is in the final locking position.

[0079] The third groove opening 62 is provided, for example, on the third locking element 7, wherein the third positioning block 120 is arranged on the housing 6, specifically on the perforated wall of the insertion hole 65. More specifically, the third locking element 7 comprises two positioning arms 73, which are spaced apart along the third direction on opposite sides of the locking arm 71, and the two positioning arms 73 are each connected to the locking arm 71 and inserted into the insertion hole 65, with the third groove opening 62 being formed on the positioning arm 73. To simultaneously reduce the difficulty of disassembling and assembling the third locking element 7, the third locking element 7 also has a push-pull plate 74 that connects the locking arm 71 and an end of the positioning arm 73 that is located outside the housing 6.

[0080] To facilitate the application of force to the third snap element 64 for releasing the docking connector from the connection, with further reference to Fig.23 The ends of the two third elastic arms 641 facing away from the connecting rod 642, i.e., the ends of the two third elastic arms 641 lying outside the housing 6, are connected to a U-shaped connecting block 644, with each of the two third elastic arms 641 being connected to two ends of the connecting block 644. By applying pressure to the connecting block 644, the third elastic arm 641 can be moved away from the third clamping block under the action of the lever, thereby separating the third elastic arm 641 from the third clamping block. The locking arm 71 of the third locking element 7 passes through the connecting block 644 and is then inserted into the housing 6, so that the unlocking of the third locking element 7 and the unlocking of the third snap element 64 do not interfere with each other.

[0081] During assembly of the above connector, the injection-molded first locking element 5 is first inserted into the insulating body 1 along the third direction, so that the first locking element 5 is in the pre-installed position, and then the second sealing ring 9 is placed onto the insulating body 1. Simultaneously, the injection-molded second locking element 4 is inserted into the second mounting hole 11 along the first direction, so that the second locking element 4 is in the pre-installed position, and then the first sealing ring 8 is installed in the mounting groove 110; subsequently, the housing 6 is placed onto the insulating body 1 and the third locking element 7 is inserted into the housing 6, finally the second terminal 2 and the first terminal 3 are inserted, and if necessary, the second locking element 4 and the first locking element 5 are pushed into the final locking position.

[0082] If the second terminal 2 needs to be removed from the second mounting hole 11 to be replaced by a new second terminal 2, the second locking element 4 can be removed from the insulating body 1 using a tool, and then the second locking element is inserted into the second mounting hole 11 using a tool, lifting the second snap element 13 towards the hole wall of the second mounting hole 11, thus allowing the second terminal 2 to be separated from the insulating body 1, effectively reducing the cost of troubleshooting;If the first terminal 3 needs to be removed from the first mounting hole 12 to be replaced by a new first terminal 3, a force can be applied away from the insulating body 1 along the third direction to the first locking element 5 via the force application groove 521, thereby removing the first locking element 5 from the insulating body 1. Subsequently, the first locking element is inserted into the first mounting hole 12 with a tool to exert a force on the first snap element 14 and push it away from the first terminal 3, so that the first snap element 14 is separated from the first terminal 3 and thus the first terminal 3 can be separated from the insulating body 1.If the docking connector needs to be separated from the connector, pressure is applied to the push-pull plate 74 of the third locking element 7 to release the end of the third locking element 7 that is engaged with the third snap element 64 from the third snap element 64, and then the third locking element 7 is pulled out of the housing 6. If pressure is applied to the connecting block 644 of the third snap element 64 to release the end of the third snap element 64 that is engaged with the docking connector from the docking connector, the docking connector can be pulled out of the housing 6.
