Abstract
Description

[0030] Since a frame-shaped foam is provided on the lower surface of the connector, the components on the connector are arranged inside the closed space formed by the frame-shaped foam and the connector, and double-sided adhesive is provided on the bottom of the frame-shaped foam, the frame-shaped foam is fixed to the lower surface of the connector by double-sided adhesive, so that the pins on the connector can be well protected, and the metal pins of the connector are separated from the blister tray, thereby preventing the FPC from being damaged by swinging during transportation, preventing the quality risk of display abnormality, and improving the competitiveness of the product.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.
[0032] Example 1
[0033] See also Figure 1, a camera module for avoiding FPC damage is provided by the utility model, which includes a module body 1, PCB2 and FPC3, the PCB2 is fixed below the module body 1, the FPC3 is arranged at one end of the PCB2 and is electrically connected to the PCB2, a connector 4 is arranged on the FPC3, pins are arranged on the connector 4, a frame-shaped foam 5 is arranged on the lower surface of the connector 4, components on the connector 4 are arranged in a closed space formed by the frame-shaped foam 5 and the connector 4, a double-sided adhesive is arranged on the bottom of the frame-shaped foam 5, and the frame-shaped foam 5 is fixed to the lower surface of the connector 4 by the double-sided adhesive. Since a frame-shaped foam 5 is provided on the lower surface of the connector 4, the components on the connector 4 are arranged inside the closed space formed by the frame-shaped foam 5 and the connector 4, and a double-sided adhesive is provided on the bottom of the frame-shaped foam 5, the frame-shaped foam 5 is fixed to the lower surface of the connector 4 by the double-sided adhesive, so that the pins on the connector 4 can be well protected, so that the metal pins of the connector 4 are separated from the blister tray, avoiding damage to the FPC3 due to swinging during transportation, preventing the quality risk of display abnormality, and improving the competitiveness of the product.
[0034] Example 2
[0035] See also Figure 2 and Figure 3 As a further optimization scheme of Example 1, in this embodiment, the lower surface of the side wall of the module body 1 is provided with an inner groove 11 arranged around the side wall of the module body 1, and the inner groove 11 is provided with an adhesive layer 12, and the PCB2 is bonded to the side wall of the module body 1 through the adhesive layer 12. The adhesive layer 12 in this embodiment is glue. When applying the glue, it is noted that the amount of glue should not exceed the lower surface of the side wall, and the glue should be filled in the inner groove 11. In this way, after the glue is cured, it can ensure that the glue and the side wall have sufficient bonding area, and no pulling force that deforms the PCB2 is generated. Since the inner groove 11 is coated with glue and the glue will not overflow, the pulling force generated after curing is concentrated in the direction perpendicular to PCB2 and will not cause deformation of PCB2, thereby avoiding changes in the flatness of PCB2 with an optical sensor caused by the oblique pulling force generated after the glue shrinks, thereby avoiding changes in the positions of the lens and the optical sensor, and preventing the clarity of the central area of the picture taken by the camera module from being unable to be fixed in the clearest position, thereby improving product yield, reducing product costs, and improving product competitiveness.
[0036] Furthermore, at least one exhaust groove 13 is provided on the inner groove 11. When the side wall of the module body 1 is pressed onto the glue, the air in the inner groove 11 can be exhausted, so that the glue can smoothly fill the space of the inner groove 11 and prevent the generation of bubbles.
[0037] Furthermore, the module body 1 has four side walls, which are connected in pairs.
[0038] Furthermore, three exhaust slots 13 are provided on the side wall of each module body 1 to allow air to be exhausted.
[0039] Furthermore, the adhesive layer 12 is AA glue.
[0040] Example 3
[0041] See also Figure 4 As a further optimization scheme of Example 1, in this embodiment, the FPC3 includes a substrate layer 31, a circuit layer 32 arranged on the upper surface of the substrate layer 31, and a metal heat dissipation layer 33 arranged on the lower surface of the substrate layer 31. The arrangement method can be that the circuit layer 32 and the metal heat dissipation layer 33 are respectively attached to the substrate layer 31 by double-sided adhesive. Since the thickness of the substrate layer 31 is relatively thin, the heat on the FPC3 can be diffused to the metal heat dissipation layer 33 through the substrate layer 31. The metal heat dissipation layer 33 can effectively increase the heat dissipation area of the FPC3 and play a role in uniform heat dissipation, thereby improving the heat dissipation efficiency of the FPC3. The substrate layer 31 can be any one of polyimide, polyester, polysulfone or polytetrafluoroethylene, the double-sided adhesive is any one of an acrylic adhesive layer or an epoxy resin adhesive layer, and the metal heat dissipation layer 33 can be a copper foil layer.
[0042] Furthermore, the FPC 3 further includes at least one through-hole 34 penetrating the substrate layer 31, the circuit layer 32 and the metal heat dissipation layer 33, and the inner wall of the through-hole 34 is provided with a heat-conducting layer in contact with the circuit layer 32 and the metal heat dissipation layer 33. By utilizing the good thermal conductivity of the through-hole 34, the circuit layer 32 and the metal heat dissipation layer 33 on both sides of the substrate layer 31 can be electrically connected, and a good thermal conductivity function can be exerted, and the thermal conductive layer can provide a thermal conductive function to achieve a good heat dissipation effect. Among them, the thermal conductive layer can be a copper glue conductive ink layer.
[0043] Furthermore, a heat conductor connected to an external heat-conducting structure is disposed in the through hole 34. The heat conductor is connected to the external heat-conducting structure from one side of the circuit layer 32 and is also in contact with the heat-conducting layer in the through hole 34, so that the circuit layer 32 and the metal heat dissipation layer 33 can be connected to the external heat-conducting structure through the through hole 34, so that the heat in the FPC 3 is diffused to the external heat-conducting structure through the heat conductor in the through hole 34, so as to further improve the heat dissipation efficiency of the FPC 3. Preferably, in order to enable the through hole 34 to be connected to the external heat-conducting structure, the through hole 34 is disposed at the edge of the FPC 3.
[0044] Furthermore, the metal heat dissipation layer 33 is a uniform heat dissipation structure, and its structure can be any one of a mesh structure, a strip structure, a wavy structure or a honeycomb structure. Through the uniform heat dissipation structure, the heat dissipation effect can be better improved.
