Abstract
Description
Technical Field
[0001] The utility model relates to an assembly structure of an electronic device, in particular to an assembly structure of an electronic device connected to a cable. Background Art
[0002] For an electronic device connected to a cable and used in a medical instrument, the safety standards such as wire waterproofing and tensile strength are generally relatively high compared to ordinary electronic instruments. Traditionally, the means to achieve waterproofing in an electronic device is to fill the encapsulation shell of the electronic device with glue to prevent water from coming into contact with the circuit board of the electronic device. However, the form of filling with glue will cause the following two problems: First, air bubbles are generated when filling with glue, and the space in the encapsulation shell of the electronic device cannot be filled; Second, when the filled glue encounters high and low temperatures, the phenomenon of thermal expansion and contraction occurs, causing damage to the electronic components on the circuit board. Therefore, in the actual production process, products using the above-mentioned glue filling form as a waterproof means often have the situation of short circuits in the finished products, affecting the production yield.
[0003] In addition, since the operation of filling with glue is relatively difficult to control, and in order to reduce the generation of air bubbles, the glue cannot be filled quickly. Therefore, the assembly efficiency of the electronic device produced in the above-mentioned manner is low, and the circuit board after filling with glue cannot be used again even if it is disassembled.
[0004] It can be seen that it is necessary to develop a new assembly structure of an electronic device to solve the above problems. Summary of the Utility Model

[0011] Therefore, the advantages of the present utility model are as follows. After the electronic device is wrapped by the inner shell assembly and then placed inside the outer shell assembly, the inner shell assembly provides waterproof guarantee for the electronic device, so that the waterproofing method of pouring glue into the outer shell assembly is not necessary. Therefore, the present utility model can improve the assembly efficiency and avoid damage to the electronic components on the circuit board. If the circuit board is disassembled, it can be reused instead of being discarded, thus reducing the production cost.

[0027] The assembly structure of the electronic device of the present invention includes an inner housing assembly 10 and an outer housing assembly 20.
[0028] The electronic device A is disposed inside the inner housing assembly 10, and the cable B penetrates through the inner housing assembly 10. The inner housing assembly 10 includes an inner housing unit 11 and at least one waterproof member 12.
[0029] The inner shell unit 11 forms an installation space 110 around it, and the electronic device A is located in the installation space 110. Specifically, the inner shell unit 11 includes an upper cover 111, a lower cover 112, and at least one sleeve 113. The upper cover 111 and the lower cover 112 are joined to each other and recessed away from each other, whereby the installation space 110 is located between the upper cover 111 and the lower cover 112. Among them, the upper cover 111 and the lower cover 112 jointly form two opposite openings, and two cables B connected to the electronic device A respectively pass through the two openings.
[0030] The sleeve 113 is connected to the upper cover 111 and the lower cover 112, and the cable B passes through the sleeve 113. In this embodiment, there are two sleeves 113, which are respectively connected to the positions of the two openings jointly formed by the upper cover 111 and the lower cover 112. Specifically, each sleeve 113 is fitted and arranged at the opening jointly formed by the upper cover 111 and the lower cover 112, whereby it is convenient for assembly during production.
[0031] Furthermore, the shape of each sleeve 113 in this embodiment is a funnel shape, and it has a connection port 1131 and a wire passing port 1132, wherein the connection port 1131 is larger than the wire passing port 1132. And each sleeve 113 is sleeved and fitted at the position of the opening of the upper cover 111 and the lower cover 112 with the connection port 1131, whereby the sleeve 113 is fixed to the upper cover 111 and the lower cover 112, so that the upper cover 111 and the lower cover 112 are connected to each other, but not limited thereto. Each cable B passes through the wire passing port 1132, and the size of the wire passing port 1132 is approximately equal to the cross-sectional size of the cable B, but not limited thereto.
[0032] Preferably, the inner shell unit 11 can be formed with at least one installation groove 1133, which is recessed on the outer surface of the inner shell unit 11, and the installation groove 1133 extends along the circumferential direction of the inner shell unit 11 and surrounds the inner shell unit 11. In this embodiment, the inner shell unit 11 is formed with two installation grooves 1133, and the two installation grooves 1133 are respectively located near the connection ports 1131 of the two sleeves 113, but not limited thereto.
[0033] The waterproof member 12 is hermetically arranged between the outer surface of the inner shell unit 11 and the inner surface of the outer shell assembly 20. Specifically, there are two waterproof members 12 in this embodiment, which are respectively arranged on the outer surfaces of the two sleeves 113. Furthermore, the waterproof member 12 in this embodiment is preferably a waterproof ring, whereby each waterproof member 12 is sleeved on the installation groove 1133 on the corresponding sleeve 113, and also makes the seams between the two sleeves 113 and the upper cover 111 and the lower cover 112 located between the two waterproof members 12.
[0034] Preferably, the present utility model can also have at least one spacer B1, which is arranged at one end of at least one cable B connected to the electronic device A and is hermetically arranged between at least one cable B and the inner shell assembly 10. Specifically, in this embodiment, there are two spacers B1, which are respectively sleeved on one end of the two cables B connected to the electronic device A, and the two spacers B1 in this embodiment are also connected to the electronic device A, thereby increasing the tensile strength of the cable B. Since the spacer B1 is hermetically arranged between the cable B and the housing 113 of the inner shell unit 11, the spacer B1 can effectively prevent moisture from entering the electronic device A through the surface of the cable B, the wire stop 22, and the housing 113, further ensuring the waterproof effect.
[0035] Preferably, the inner shell unit 11 can further form a positioning protrusion 1121, which protrudes from the inner surface of the inner shell unit 11 and is located at the position of the positioning groove A1 of the electronic device A.
