Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic shielding of circuit board components, in particular to a connector assembly and a shielding sealing assembly. Background Art

[0002] As people's demand for driving safety continues to increase, car cameras are becoming an indispensable part of cars. Generally, car cameras transmit signals through the rear end of the camera module and the body wiring harness. In order to prevent rain, sand and dust from entering the camera module, the airtightness of the rear end of the camera module needs to be ensured. In addition, for electronic devices such as camera modules, electromagnetic shielding (EMC) structures are required. Therefore, the connector plug-in part needs to ensure grounding contact shielding between components.

[0003] At present, the board-side connector of the mainstream camera module needs to be connected to the vehicle body wiring harness through an adapter fixed to the camera housing. Separate adapters and camera housings are prone to sealing problems. Some camera module adapters are integrated with the camera housing. Although this can solve the sealing problem, whether it is a split adapter or an integrated adapter, it is necessary to reserve space in the camera housing to connect with the board-side connector, thereby increasing the size of the camera module and being unfavorable for the miniaturization of the camera module. In addition, the transfer structure of the board-side connector and the adapter is prone to impedance discontinuity and model transmission loss, resulting in signal loss output by the camera module. Utility Model Content

[0004] Based on this, it is necessary to provide a connector assembly and a shielding sealing assembly to address the problem that the existing connection structure between the board-end connector and the adapter of the camera module is not conducive to the miniaturization of the camera module.

[0006] A connector, the connector comprising a connecting portion for electrically connecting to a circuit board and a plug-in portion integrally connected to the connecting portion, the plug-in portion being used to pass through a connector via hole of a camera housing and electrically connected to a vehicle body wiring harness;

[0007] A spring sheet, which is clamped on the connecting portion and is used for conducting the connector and the camera housing; and

[0008] A sealing member is sleeved on the plug-in portion and is used to cooperate with the camera housing to seal the connector via.

[0009] In one embodiment, the circumferential dimension of the connecting portion is greater than that of the plugging portion.

The first clamping portion is clamped to the connecting portion, and the second clamping portion is arranged around the plugging portion for clamping to the camera housing.

[0010] In one embodiment, the first clamping portion includes a first elastic arm that converges inward from the elastic piece body, a second elastic arm that bends outward from the first elastic arm, and a third elastic arm that extends outward from the second elastic arm.

[0011] In one embodiment, the connector further includes a plurality of clamping protrusions protruding from the outer periphery of the connecting portion. The first clamping portion has a clamping interface, and the clamping protrusions are respectively clamped in the clamping interfaces.

[0012] In one embodiment, the second clamping portion includes a fourth elastic arm that converges inward from the elastic piece body, a fifth elastic arm that bends outward from the fourth elastic arm, and a sixth elastic arm that extends outward from the fifth elastic arm.

[0013] In one embodiment, the seal includes a seal body sleeved on the plugging portion and a plurality of seal protrusions. The seal protrusions are arranged at intervals on the outer wall of the seal body.

[0014] In one embodiment, the connector further includes a limiting portion arranged around the plugging portion. The seal is located between the limiting portion and the connector.

[0015] In one embodiment, the connector further includes a fixing protrusion protruding from the plugging portion. The fixing protrusion is located on the side of the limiting portion away from the seal.

[0016] In one embodiment, the plugging portion has a guiding groove, and the guiding groove extends from the limiting portion along the axial direction of the connector to the end of the plugging portion away from the connecting portion.

The seal of the connector assembly is hermetically arranged in the sealing groove for sealing the connector through hole, and the second clamping portion of the connector assembly is clamped to the sealing portion.

[0021] The above shielding and sealing assembly uses the connector assembly to replace the conventional board - end connector and adapter transfer structure.

[0034] Based on the problem that the existing board-end connector and adapter transfer structure of the camera module is not conducive to the miniaturization of the camera module, a connector assembly and a shielding sealing assembly are provided. The shielding sealing assembly uses the connector assembly to replace the traditional board-end connector and adapter transfer structure, and can cooperate with the housing of the camera module to form a sealed and electrically conductive structure, which is conducive to the miniaturization of the camera module.

[0035] For details, please refer to Figures 1 to 5, the connector 10 assembly may include a connector 10, a spring piece 20, and a seal 30. The connector 10 includes a connection portion 11 and a plugging portion 12. The plugging portion 12 is integrally connected to the connection portion 11. The connection portion 11 is used for electrical connection to a circuit board 40. The plugging portion 12 is used to pass through a connector through-hole 54 of a camera housing 50 and is electrically connected to a vehicle body wiring harness. The spring piece 20 is snap-connected to the connection portion 11 and is used to conduct electricity between the connector 10 and the camera housing 50. The seal 30 is sleeved on the plugging portion 12 and is used to cooperate with the camera housing 50 to seal the connector through-hole 54.

[0036] It can be understood that by matching the connector 10 with the sealing ring and the spring piece 20, the connector 10 assembly can cooperate with the camera housing 50 to form a sealed and electrically conductive structure, which is different from the conventional adapter structure of the connector 10 and the adapter. The number of components is reduced, the cost of the camera module is lowered, the overall volume of the connector 10 assembly is smaller than that of the conventional adapter structure, and the camera module can be made more miniaturized. In addition, compared with the conventional adapter structure, the connector 10 adopts a direct signal output method, which can reduce signal loss.

[0037] Optionally, as Figure 3 shown, in one embodiment, the circumferential dimension of the connection portion 11 is greater than the circumferential dimension of the plugging portion 12. The spring piece 20 includes a spring piece body 21, a first snap-connection portion 22, and a second snap-connection portion 23. The first snap-connection portion 22 is circumferentially arranged at intervals on one side of the spring piece body 21. The second snap-connection portion 23 is circumferentially arranged at intervals on the other side of the spring piece body 21. The spring piece body 21 is sleeved on the plugging portion 12. The first snap-connection portion 22 is snap-connected to the connection portion 11. The second snap-connection portion 23 is arranged around the plugging portion 12 and is used for snap-connection to the camera housing 50. With such an arrangement, the spring piece 20 is snap-connected and fixed to the connection portion 11 through the first snap-connection portion 22, and the spring piece 20 is snap-connected and fixed to the camera housing 50 through the second snap-connection portion 23, so that the spring piece 20 can be firmly connected to the connector 10 and the camera housing 50, preventing the spring piece 20 from detaching from the connector 10 or the camera housing 50, which may cause the disconnection between the connector 10 and the camera housing 50 and affect the electromagnetic shielding effect.

[0038] Optionally, as Figure 4As shown, in one embodiment, the first clamping portion 22 includes a first elastic arm 221 that converges inward from the elastic sheet body 21, a second elastic arm 222 that bends outward from the first elastic arm 221, and a third elastic arm 223 that extends outward from the second elastic arm 222. The third elastic arm 223 is used to guide the connecting portion 11 so that the connecting portion 11 slides into between the second elastic arms 222. The first elastic arm 221 is used to make the second elastic arms 222 have a tendency to converge inward, so that the second elastic arms 222 can clamp the connecting portion 11.

[0039] Optionally, in one embodiment, the connector 10 further includes a plurality of clamping protrusions 13. The clamping protrusions 13 protrude from the outer periphery of the connecting portion 11. The first clamping portion 22 has a clamping interface 224, and the clamping protrusions 13 are respectively clamped in the clamping interface 224. The clamping protrusions 13 can limit the second elastic arms 222, and can make the first clamping portion 22 more firmly clamped to the connecting portion 11, preventing the elastic sheet 20 from falling off the connector 10 due to vibrations or collisions generated during vehicle driving, which affects the electromagnetic shielding effect.

[0040] Preferably, as Figure 4 shown, in one embodiment, one side of the clamping protrusion 13 close to the plugging portion 12 has an inclined guiding surface 131. The guiding surface 131 can cooperate with the third elastic arm 223 to guide the clamping protrusion 13 into the clamping interface 224. Thus, the first clamping portion 22 can be more easily clamped to the connecting portion 11.

[0041] Optionally, as Figure 5 shown, in one embodiment, the second clamping portion 23 includes a fourth elastic arm 231 that converges inward from the elastic sheet body 21, a fifth elastic arm 232 that bends outward from the fourth elastic arm 231, and a sixth elastic arm 234 that extends outward from the fifth elastic arm 232. The sixth elastic arm 234 has a guiding function and can make the clamping portion of the camera housing 50 slide into between the fourth elastic arm 231 and the fifth elastic arm 232. The fourth elastic arm 231 is used to make the fourth elastic arm 231 have a tendency to converge inward, so that the fifth elastic arm 232 can clamp the clamping portion of the camera housing 50.

[0042] Exemplarily, in one embodiment, the elastic sheet 20 includes two first clamping portions 22 and six second clamping portions 23. The two first clamping portions 22 are symmetrically arranged along a symmetric direction of the elastic sheet body 21, and the six second clamping portions 23 are symmetrically arranged along another direction perpendicular to the above symmetric direction.

[0043] It should be noted that the first clamping portion 22 and the second clamping portion 23 can be integrally formed by cutting and stamping.

[0044] Optionally, as Figure 1 and Figure 2 shown, in one embodiment, the seal 30 includes a seal body 31 and a plurality of seal protrusions 32. The seal body 31 is sleeved on the insertion portion 12, and the seal protrusions 32 are arranged at intervals on the outer wall of the seal body 31. With this arrangement, the seal 30 can form a side pressure seal structure with the camera housing 50. The plurality of seal protrusions 32 can not only increase the seal points with the camera housing 50, enhance the sealing effect of the seal 30, but also make the seal 30 easier to install.

[0045] Preferably, as Figure 3 shown, in one embodiment, the connector 10 further includes a limiting portion 14. The limiting portion 14 is disposed around the insertion portion 12, and the seal 30 is located between the limiting portion 14 and the connector 10. The limiting portion 14 can limit the seal 30 to prevent the seal 30 from detaching from the insertion portion 12.

[0046] Preferably, in one embodiment, the distance between the limiting portion 14 and the connector 10 is greater than or equal to the axial length of the seal 30. Controlling the distance between the limiting portion 14 and the connector 10 can provide a certain amount of movement space for the seal 30, enabling the seal 30 to achieve a better sealing effect.

[0047] Optionally, as Figure 3 shown, in one embodiment, the connector 10 further includes a fixing protrusion 15. The fixing protrusion 15 protrudes from the insertion portion 12, and the fixing protrusion 15 is located on the side of the limiting portion 14 away from the seal 30. The fixing protrusion 15 is used to cooperate with the vehicle body wiring harness to fixedly connect the insertion portion 12 to the wiring harness.

[0048] Preferably, as Figure 3 shown, in one embodiment, the insertion portion 12 has a guiding groove 16. The guiding groove 16 extends from the limiting portion 14 along the axis direction of the connector 10 to the end of the insertion portion 12 away from the connecting portion 11. The guiding groove 16 is used to cooperate with the vehicle body wiring harness to guide the wiring harness to be inserted into the insertion portion 12, avoiding problems such as reverse installation or misinstallation.

[0049] Further, please refer to Figure 1 and Figure 2, the shielding and sealing assembly may include a circuit board 40, a camera housing 50, and the connector 10 assembly as described in any of the above. The circuit board 40 is fixedly installed inside the camera housing 50. The camera housing 50 includes a housing body 51, a sealing portion 52, and an interface portion 53. The sealing portion 52 protrudes from the inner side of the housing body 51. The sealing portion 52 is provided with a sealing groove 521. The interface portion 53 protrudes from the outer side of the housing body 51. The interface portion 53 is provided with an interface groove 531. There is a connector through-hole 54 between the sealing groove 521 and the interface groove 531. The connecting portion 11 of the connector 10 of the connector 10 assembly is electrically connected to the circuit board 40. The plugging portion 12 of the connector 10 of the connector 10 assembly passes through the through-hole from the sealing groove 521 into the interface groove 531. The seal 30 of the connector 10 assembly is hermetically arranged in the sealing groove 521 for sealing the connector through-hole 54. The second clamping portion 23 of the connector 10 assembly is clamped to the sealing portion 52.

[0050] By integrating the connector 10, the elastic sheet 20, and the seal 30 into the connector 10 assembly, the shielding and sealing assembly does not require multiple assembly processes during assembly, and the production is convenient.

[0051] It should be noted that the connector 10, the elastic sheet 20, and the camera housing 50 are all made of electrically conductive materials, and there is no surface insulation treatment at the parts where the elastic sheet 20 contacts the connector 10 and the camera housing 50.

[0052] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0053] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
