Description

Technical Field

[0001] The utility model relates to the technical field related to cameras, and in particular to a binocular camera. Background Art

[0002] At present, camera products have been increasingly widely used in people's daily lives. In order to meet people's requirements for convenient carrying of electronic products, it is necessary to produce advanced electronic products with small size and light weight. For this reason, it is necessary to reduce the structure of electronic products and make them compact. The shielding of key components on PCBA has already had an impact on the EMC performance and miniaturization of products. The local shielding solution on structural parts and PCBA plays an important role in improving the EMC performance of electronic products and miniaturizing the shell structure of electronic products.

[0003] There are many ways to shield between structural parts and PCBA. The most common method is to use a metal shielding cover made of sheet metal on the PCBA, such as Figure 1 As shown ( Figure 1 This is a screenshot of part of the metal shielding cover, so there are extra lines). The main disadvantages of this method are as follows:

[0004] 1. It is necessary to reserve holes on the PCBA board for installing the shield cover pins, or metal springs for the patch, for assembling the metal shield cover; it is necessary to occupy an area of a certain width on the PCBA.

[0005] 2. The metal shield cannot be soldered together with electronic components, and requires additional manual assembly, which affects the production efficiency of the product.

[0006] 3. There are also microscopic gaps between the side wall of the shielding cover and the exposed copper layer of the PCBA. There is still a certain amount of radiation, and a complete conductive shielding body cannot be formed.

[0007] 4. If shielded devices are required and heat dissipation is required, it is necessary to make grooves / holes (larger) on the top surface of the shielding cover, which may cause deformation of the shielding cover and further affect the contact between the side wall of the shielding cover and the exposed copper layer of the PCBA.

[0008] 5. The shielding cover has a certain height. Adding parts of this height inside the product may affect the design of the inner cavity height of the product and affect the miniaturization design of the product. Utility Model Content

[0047] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0048] Embodiment 1

[0049] As Figures 2 to 7 shown, a binocular camera in this embodiment includes a PCBA board 3 and a camera housing. The PCBA board 3 is installed inside the camera housing. A copper exposed grounding layer 31 is provided around the device 33 to be shielded on the PCBA board 3. The side surface of the camera housing opposite to the PCBA board 3 is an installation surface, and a shielding rib 11 is provided on the installation surface. The shape of the shielding rib 11 is the same as that of the copper exposed grounding layer 31. The free end of the shielding rib 11 is in conductive contact with the copper exposed grounding layer 31.

[0050] In this embodiment, the free end of the shielding rib 11 is in direct contact with the copper exposed grounding layer 31.

[0051] Referring to Figures 3 to 6 shown, bolt connection posts 13 are also provided on the installation surface. The bolt connection posts 13 are arranged on the shielding rib 11 or spaced outside the shielding rib 11 or spaced inside the shielding rib 11.

[0052] Connection holes 32 are provided on the PCBA board 3. The connection holes 32 are arranged on the copper exposed grounding layer 31 or spaced outside the copper exposed grounding layer 31 or spaced inside the copper exposed grounding layer 31.

[0053] The threaded holes 14 on the bolt connection posts 13 are arranged corresponding to the connection holes 32 and are fixedly connected by bolts. By providing the bolt connection posts and the connection holes, the effective and stable connection between the PCBA board and the camera housing is facilitated.

[0054] Specifically, the height of the bolt connection posts 13 is the same as the height of the shielding rib 11.

[0055] A binocular camera in this embodiment, without expanding the size and weight of the original device, provides a shielding rib on the installation surface inside the camera housing. Through the direct conductive contact between the shielding rib and the copper exposed grounding layer, a local shielding cavity is constructed, minimizing the occupation of the limited area on the PCBA board, improving the grounding performance between the metal structural parts of the device and the PCBA board, and ensuring the reliability of forming a complete shielding body locally.

[0056] Embodiment 2

[0057] As Figures 2 to 7As shown in the figure, a binocular camera in this embodiment includes a PCBA board 3 and a camera housing. The PCBA board 3 is installed inside the camera housing. A copper-exposed grounding layer 31 is provided around the device 33 to be shielded on the PCBA board 3. One side of the camera housing opposite to the PCBA board 3 is an installation surface, and a shielding rib 11 is provided on the installation surface. The shape of the shielding rib 11 is the same as that of the copper-exposed grounding layer 31. The free end of the shielding rib 11 is in conductive contact with the copper-exposed grounding layer 31.

[0058] As Figures 3 to 6 shown in the figure, the free end of the shielding rib 11 abuts against the copper-exposed grounding layer 31 through a conductive adhesive 12. By providing a conductive adhesive at the free end of the shielding rib, the gap-filling performance of the conductive adhesive after being extruded is much better than the hard contact of metal parts, and the formed conductive contact is reliable, and there is no gap between the PCBA board and the shielding rib.

[0059] As Figures 3 to 6 shown in the figure, bolt connection posts 13 are also provided on the installation surface. The bolt connection posts 13 are provided on the shielding rib 11 or are spaced outside the shielding rib 11 or are spaced inside the shielding rib 11. Connection holes 32 are provided on the PCBA board 3. The connection holes 32 are provided on the copper-exposed grounding layer 31 or are spaced outside the copper-exposed grounding layer 31 or are spaced inside the copper-exposed grounding layer 31. The threaded holes on the bolt connection posts 13 are arranged corresponding to the connection holes 32 and are fixedly connected by bolts. By providing bolt connection posts and connection holes, it is convenient to effectively and stably connect the PCBA board and the camera housing.

[0060] Specifically, when the bolt connection posts 13 are provided on the shielding rib 11, the conductive adhesive 12 is provided on the shielding rib 11 on both sides of the bolt connection posts.

[0061] As Figures 3 to 6 shown in the figure, when the bolt connection posts 13 are spaced outside the shielding rib 11 or are spaced inside the shielding rib 11, the connection holes 32 are spaced outside the copper-exposed grounding layer 31 or are spaced inside the copper-exposed grounding layer 31. The shielding rib 11 is a ring-shaped cylinder structure with a uniform thickness, and the copper-exposed grounding layer 31 is a ring-shaped structure with a uniform width. A ring of conductive adhesive 12 is provided at the free end of the shielding rib 11. By arranging the bolt connection posts outside or inside the shielding rib, the bolt connection posts do not contact the shielding rib, and the connection holes do not connect with the copper-exposed grounding layer, so that the entire shielding rib and the copper-exposed grounding layer are completely in soft contact, and the contact connection effect is more stable and reliable.

[0062] The conductive adhesive 12 is provided at the free end of the shielding rib 11 and remains elastic after solidification. When the PCBA board 3 is assembled, it causes a 20% - 30% extrusion deformation to the conductive adhesive, so as to achieve a good airtight contact between the cavity formed by the shielding rib and the copper-exposed grounding layer on the PCBA board, form a complete conductive shielding body, and does not affect the heat dissipation of the device in the shielding cavity.

[0063] Among them, when setting the conductive adhesive, the height of the bolt connection column 13 can be higher than that of the shielding rib 11, so that the bolt connection column is tightly connected to the PCBA board. Further, when the PCBA board 3 is not installed with the camera housing, the sum of the heights of the shielding rib 11 and the conductive adhesive 12 is greater than the height of the bolt connection column 13. When the PCBA board is installed with the camera housing, the conductive adhesive can be extruded to a certain extent, increasing the connection stability.

[0064] For the binocular camera of this embodiment, it only needs to apply glue at the specified position on the shielding rib before mass production line. There is no need to perform any soldering or assembly operations on the PCBA board before and after soldering. It will not cause electrostatic damage to the PCBA board, and does not affect the operation procedures and assembly processes of each component on the mass production line, does not affect the production rhythm and efficiency, and does not affect the heat dissipation path of the components to be shielded inside the shielding rib; the gap filling performance of the conductive adhesive after being compressed is much better than the hard contact of metal parts, and the formed conductive contact is reliable. There is no gap between the PCBA board and the shielding rib, and the shielding effect is good.

The setting of the heat conduction boss can cooperate with the heat conduction gasket to effectively export the heat of the device to be shielded.

[0068] As Figures 3 to 6 shown, a guide post 16 is provided on the installation surface, and a guide hole is provided on the PCBA board 3. The guide post 16 is adaptively inserted into the guide hole. The setting of the guide post and the guide hole facilitates the precise assembly between the PCBA board and the camera housing.

[0070] As Figure 8 shown, the camera housing includes a front camera housing 1 and a rear camera housing 5. The rear camera housing 5 is snap-fitted and fixed to the front camera housing 1. The middle position of the inner side surface of the front camera housing 1 is the mounting surface. Two sets of monocular components 2 are mounted on the front camera housing 1, and the two sets of monocular components 2 are located on both sides of the PCBA board 3. In this embodiment, the front camera housing 1 and the rear camera housing 5 are arranged with the PCBA board 3 as the middle position, one in front and one behind.

An interface connector 7 is also provided on the rear camera housing 5, and the interface connector 7 is specifically a Fakra interface connector. A thermal conductive gasket 6 is also provided at the part where the rear camera housing 5 contacts the PCBA board 3.

[0072] The binocular camera of this embodiment has a device shielding structure. Without increasing the size and weight of the original device, a circle of shielding ribs is arranged on the mounting surface inside the camera housing. The shielding ribs can be in direct contact with the copper-exposed grounding layer, or a conductive adhesive can be set at the free end of the shielding ribs. After being extruded, the gap-filling performance of the conductive adhesive is much better than the hard contact of metal parts, and the formed conductive contact is reliable. There is no gap between the PCBA board and the shielding ribs, constructing a local shielding cavity, occupying as little limited area on the PCBA board as possible, improving the grounding performance between the metal structure parts of the device and the PCBA board, and ensuring the reliability of forming a complete shielding body locally.
