Technical Field
[0001] The utility model relates to a connection structure, in particular to a connection structure for a camera module. Background Art
[0002] With the development and progress of science and technology, people have higher and higher requirements for mobile phone photography, so there are more and more cameras on mobile phones, so the development of cameras is also faster and faster. The camera module is an important component of the camera.
[0003] The existing camera module includes an optical lens, a photosensitive element, a digital processor, a memory, a connector, and a microphone. The above components are integrated on the PCB board and connected to the computer. Among them, the microphone is an important component on the camera module, and 99% of the camera modules are equipped with a microphone. At present, the problem of microphone audio failure often occurs during use. After many studies, it was found that this is because the microphone is located between the iron shell and the connector. When the connector is manually plugged in and out, the connector is buckled down and force is applied downward. Because the PCB is too thin, the connector and the microphone, and the microphone and the iron shell will be forced upward. The routing line between the microphone, the iron shell and the connector is set horizontally, which can easily cause the outer pad and line of the microphone to break, causing the microphone to fail, thereby causing the product to be scrapped, which brings many unfavorable factors to the actual production and processing. Utility Model Content
[0004] The utility model aims to overcome the deficiencies of the prior art and to provide a connection structure of a camera module, which has low improvement cost and can effectively avoid failure of the microphone function when the connector is plugged in or out.
[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a connection structure of a camera module, comprising a connector, a microphone, a processing system and an optical lens shielded by an iron shell, and a photosensitive element for receiving light located below the optical lens, which is sequentially arranged on a circuit board, wherein the sensing element is connected to the processing system; the connector is connected to the processing system through the microphone;
[0006] Among them, the microphone includes a first pad group, a second pad group and a third pad group which are arranged in sequence on the circuit board; a first longitudinal line is led out from the first pad group in the longitudinal direction and connected to the connector through an electrical component; a third longitudinal line is led out from the third pad group in the longitudinal direction and connected to the processing system in the iron shell; a second longitudinal line is led out from the second pad group in the longitudinal direction and connected to a ground wire, and the ground wire is arranged on the circuit board.
[0007] Preferably, the first pad group, the second pad group and the third pad group are respectively two first pads, two second pads and two third pads which are arranged relatively parallel to each other vertically.
[0008] Preferably, the first pad, the second pad and the third pad have the same structure; the interior of the first pad is H-shaped, and four first longitudinal lines can be led out of the first pad.
[0009] Preferably, the first pad, the second pad and the third pad are made of gold-tin alloy.
[0010] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:
[0011] The connection structure of the camera module of the utility model leads out the first longitudinal line, the second longitudinal line and the third longitudinal line from the first pad group, the second pad group and the third pad group respectively, and then respectively connects with the connector, the processing system and the ground line. In this way, when the connector is plugged in and out up and down, because the force is the pressure from up and down, and only the lateral force is applied to the left and right during operation, the first longitudinal line, the second longitudinal line and the third longitudinal line will not be broken, thereby ensuring the normal use of the microphone. The improvement cost is low and meets the actual use needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0017] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0018] The utility model provides a connection structure of a camera module to solve the problem in the prior art that when the connector is manually plugged in and out, the outer pad and circuit of the microphone are easily broken when the connector is buckled downward, making the microphone inoperative and thus causing the product to be scrapped.
[0019] For ease of understanding, the specific process in the embodiments of the present application is described below. Figures 1 to 3 A connection structure of a camera module in an embodiment of the present application includes a connector 2, a microphone 3, a processing system 6 and an optical lens 5 shielded by an iron shell 4, and a photosensitive element for receiving light located below the optical lens 5, which are sequentially arranged on a circuit board 1, wherein the sensing element is connected to the processing system 6; the connector 2 is connected to the processing system 6 through the microphone 3; the microphone 3 includes a first pad group, a second pad group and a third pad group sequentially arranged on the circuit board 1; a first longitudinal line 31 is led out in the longitudinal direction of the first pad group and is connected to the connector 2 through an electrical component 34; a third longitudinal line 33 is led out in the longitudinal direction of the third pad group and is connected to the processing system 6 in the iron shell 4; a second longitudinal line 32 is led out in the longitudinal direction of the second pad group and is connected to a ground line 35, and the ground line 35 is arranged on the circuit board 1.
[0020] The connection structure of the camera module of the present invention leads out longitudinal lines from the first pad group, the second pad group and the third pad group respectively, and then connects to the connector, the processing system and the ground wire respectively. In this way, when the connector is plugged in and out, the force is the pressure from the top and bottom, and only the lateral force is applied during operation without the longitudinal force, which will not cause the first longitudinal line 31, the second longitudinal line 32 and the third longitudinal line 33 to be broken, thereby ensuring the normal use of the microphone.
[0021] based on Figure 3 In this embodiment, the first pad group, the second pad group and the third pad group are respectively two first pads 60, two second pads 61 and two third pads 62 which are arranged relatively parallel to each other up and down. Of course, the number of pads can be adjusted according to actual use.
[0022] Furthermore, in this embodiment, the interior of the first pad 60 is H-shaped, and four first longitudinal lines can be led out of the first pad, while the structures and lines of the second pad 61 and the third pad 62 are the same as those of the first pad 60 .
[0023] Furthermore, in order to increase the service life of the pad, a gold-tin alloy is used here.
[0024] based on Figure 3 , the connection method of the microphone, the connector and the iron shell in an embodiment is described below. In this embodiment, two first solder pads 60, two second solder pads 61 and two third solder pads 62 are arranged in parallel on the circuit board. A first longitudinal line 31 is respectively led out from the two first solder pads 60 on the left side in the longitudinal direction and connected to the corresponding electrical component 34, and then the electrical component 34 is connected to the connector 3; a third longitudinal line 33 is respectively led out from the two third solder pads 62 on the right side in the longitudinal direction and connected to the processing system in the iron shell 4, and two second longitudinal lines 32 are led out from the longitudinal position of the two second solder pads 61 and connected to the ground line. In this way, when the connector needs to be plugged in and out, since there are only lateral forces up and down and left and right, the first longitudinal line 31, the second longitudinal line 32 and the third longitudinal line 33 arranged in the longitudinal direction will not be broken. The product has high reliability, simple improvement cost, and meets the actual use needs.
[0025] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
