Description

Technical Field

[0001] This utility model relates to the field of equipment connection structure technology, and in particular to a camera back cover with a fixed structure. Background Technology

[0002] Existing camera housings are typically unibody aluminum shells. Besides providing protection, these shells also include a cylindrical wire harness mating connector that extends from the aluminum shell. The unibody design of the aluminum shell increases manufacturing costs, and also raises the cost of changing the model number. This is primarily because the wire harness mating connector is integrated with the aluminum shell; adding a model number requires new molds. Furthermore, since the wire harness mating connector and aluminum shell are integrated and share the same color, color-coding is necessary to indicate the model number.

[0003] Existing split-type camera structures have separate aluminum housings and wiring harness mating connectors. The wiring harness mating connectors are mainly fixed to the aluminum housing using snap-fit, screw, adhesive, and threaded connections. Among these, adhesive fixation has low reliability and stability. Conventional threaded connection designs (where the wiring harness mating connector is screwed into the aluminum housing) have problems with loosening and difficulty in designing foolproof features (the foolproof protrusions or grooves are easy to misalign with the design position). Screw fixation occupies a lot of volume and area and is cumbersome to assemble. Snap-fit ​​fixation has lifespan and loosening issues (mainly because repeated insertion and removal cause the snap-fit ​​reliability to gradually decrease).

[0004] Therefore, there is an urgent need for a fixed structure camera back cover that can solve one or more of the above problems. Utility Model Content

[0005] To address one or more problems existing in the prior art, this utility model provides a camera back cover with a fixed structure. The technical solution adopted by this utility model to solve the above problems is as follows: a camera back cover with a fixed structure, wherein the top surface of the back cover is provided with an insertion hole, the insertion hole communicates with a cavity on the back of the back cover, one side of the insertion hole is provided with a foolproof protrusion, the foolproof protrusion is located on the top surface of the back cover, the insertion hole is fitted with a connector housing, the connector housing is fitted with a connector assembly, the side of the cavity connected to the insertion hole is provided with a first groove, and the inner wall of the insertion hole is provided with a limiting groove; The lower end of the connector housing is a mating end. The mating end is provided with a foolproof groove that matches the foolproof protrusion. The mating end is provided with an outwardly extending mating flange. Multiple mating flanges are spaced apart and form a shape that matches the socket. The mating flanges are inserted into the socket. The connector assembly is tightly fitted into the connector housing. The lower end of the connector assembly is provided with a stop flange, which abuts against the step formed by the first groove. The outer side wall of the connector assembly is provided with a spreading flange, which pushes the mating flange into the limiting groove, so that the connector housing and the rear cover are engaged.

[0006] In some embodiments, the mating flange is an arc-shaped thin sheet structure.

[0007] In some embodiments, the outer sidewall of the connector assembly is provided with a tight-fitting flange, which is interference-fitted with the inner bore of the connector housing.

[0008] In some embodiments, the opening end of the insertion hole located on the top surface of the rear cover is provided with a mating flange, and the mating end facing the insertion hole is provided with a mating groove, which engages with the mating flange.

[0009] Furthermore, a second groove is provided on the side of the mating end facing the insertion hole, the second groove surrounds the mating groove, and a sealing ring is provided inside the second groove.

[0010] In some embodiments, the outer side wall of the connector housing is provided with a connecting flange, and the anti-fooling groove is located directly below the connecting flange.

[0017] To make the above-mentioned objectives, features, and advantages of this utility model more readily understood, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0018] This utility model discloses a fixed structure camera back cover, combined with Figures 1-5 As shown, the top surface of the back cover 1 is provided with a socket 10, which communicates with the cavity 13 on the back of the back cover 1. A foolproof protrusion 12 is provided on one side of the socket 10, which is located on the top surface of the back cover 1. The socket 10 is fitted into the connector housing 2, and the connector housing 2 is fitted into the connector assembly 3. A first groove 14 is provided on the side of the cavity 13 that connects to the socket 10. A limit groove 100 is provided on the inner wall of the socket 10. The lower end of the connector housing 2 is a mating end 20. The mating end 20 is provided with a foolproof groove 22 that matches the foolproof protrusion 12. The mating end 20 is provided with an outwardly extending mating flange 21. Multiple mating flanges 21 are spaced apart and form a shape that matches the socket 10. The mating flange 21 is inserted into the socket 10. The connector assembly 3 is tightly fitted into the connector housing 2. The lower end of the connector assembly 3 is provided with a stop flange 32, which abuts against the step formed by the first groove 14. The outer side wall of the connector assembly 3 is provided with a spreading flange 30, which pushes the mating flange 21 into the limiting groove 100, so that the connector housing 2 is engaged with the rear cover 1.

[0019] It should be noted that the anti-foolproof protrusion 12 and the anti-foolproof groove 22 form an anti-foolproof mating structure. The internal structure and composition of the connector assembly 3 are conventional structures and components, therefore, they will not be described in detail here. The engagement of the stop flange 32 and the first groove 14 restricts the disengagement of the connector assembly 3.

[0020] Combination Figure 3 As shown, the interlocking flange 21 is an arc-shaped thin sheet structure. Furthermore, the side of the spreading flange 30 facing the interlocking flange 21 is provided with a sloped surface, which guides the interlocking flange 21 to bend towards the limiting groove 100. Combined with... Figure 3 , Figure 5 As shown, the outer wall of the connector housing 2 is provided with a connecting flange 23, and the anti-fooling groove 22 is located directly below the connecting flange 23. The connecting flange 23 is hook-shaped and is used for mating and locking with an external connector. Furthermore, the connection between the stop flange 32 and the rear cover 1 can be coated with sealant 5, which improves the connection strength between components and ensures sealing.

[0021] Combination Figure 4 , Figure 5 As shown, the outer side wall of the connector assembly 3 is provided with a tight-fitting flange 31, which is interference-fitted with the inner hole of the connector housing 2 to improve the connection between the connector housing 2 and the connector assembly 3.

[0022] Combination Figure 5 As shown, the stop flange 32 of the connector assembly 3 can be tightly fitted to the first groove 14. The stop flange 32 is an outwardly expanding annular structure. Furthermore, the fixed connection between the stop flange 32 and the rear cover 1 can also include cold riveting or fixing by setting fixing points (not shown in the figure) to further improve the firmness.

[0023] Specifically, such as Figures 2-5As shown, the insertion hole 10 has a mating flange 11 at its open end on the top surface of the rear cover 1. The mating end 20 has a mating groove 201 facing the insertion hole 10, which engages with the mating flange 11. The mating end 20 also has a second groove 200 facing the insertion hole 10, surrounding the mating groove 201. A sealing ring 4 is disposed within the second groove 200. The second groove 200, the mating groove 201, and the mating flange 11 improve the accuracy of assembly and provide space for the sealing ring 4.

[0024] Specifically, such as Figure 5 As shown, the inner hole of the connector housing 2 is provided with an abutment flange 24. The abutment flange 24 surrounds the connector assembly 3. The abutment flange 24 is used to receive the insertion of the external connector and mate with it. The abutment flange 24 transmits the pressure it bears to the top surface of the rear cover 1, reducing the pressure on the connector assembly 3 when the external connector is inserted, thereby ensuring reliability.

[0025] In summary, this application reduces the manufacturing cost and difficulty of aluminum back covers by using a split design for the back cover, connector housing, and connector assembly. The connector housing and back cover are secured by a snap-fit ​​flange with a thin sheet structure that engages with the opening of the connector assembly. Combined with the tight fit between the connector assembly and the connector housing, this improves the anti-disengagement capability of each component, enhances the overall holding force of the connector on the back cover, and ultimately improves the stability and reliability of the product, especially its mating and unmating performance, ensuring the firmness of the connection between the connector and the back cover. At the same time, the product assembly is relatively simple and the cost is relatively lower.

[0026] The embodiments described above are merely illustrative of one or more implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
