Description

Electronic circuit board of anti-touch shell

Technical Field

The utility model relates to an electronic circuit board protection technical field indicates an electronic circuit board of anti-touch casing very much.

Background

With the development and progress of science and technology, electronic equipment is also miniaturized and lightened, and the installation space reserved for an electronic circuit board is smaller and smaller.

In order to reduce the planar space occupied by the electronic circuit board, the electronic circuit board is generally installed by a vertical plugging manner. This type of mounting requires the electronic circuit board to be placed in the edge area to accommodate the limited mounting space; because the electronic circuit board can produce stress when inserting and pulling, under the condition that the space layout is not enough, the electronic circuit board arranged in the edge area can touch the machine shell when in use or transportation shaking, and further the phenomenon that the touch part is damaged by the short circuit of the machine shell is caused.

In order to avoid the damage caused by touching the casing, a method of attaching insulating protective materials such as mylar sheets to a portion of the casing that may touch the electronic circuit board has been conventionally used. Although the conventional method can avoid the contact with the chassis and the electronic circuit board, the conventional method requires an additional assembly process on the production line, which undoubtedly increases the design and production costs greatly.

Therefore, how to provide an electronic circuit board capable of preventing the electronic circuit board from touching the housing to reduce the protection cost of the electronic circuit board becomes a problem to be solved urgently.

Drawings

The present invention will be further described with reference to the following examples and drawings.

Fig. 1 is a schematic structural view of an electronic circuit board of a touch-proof housing of the present invention.

Description of the labeling:

100-an electronic circuit board of a touch-proof enclosure, 1-a circuit board body, 2-a protective device and 3-a butt-joint row socket.

Detailed Description

The embodiment of the utility model provides a through providing an electronic circuit board 100 of touching casing prevents insulating protective material such as wheat pulling-on piece that pastes among the prior art for electronic circuit board provides the protection on the casing, needs increase the assembly process on the production line, and then increases design and manufacturing cost's technical problem, has realized very big reduction electronic circuit board's protection cost's technological effect.

The embodiment of the utility model provides an in technical scheme for solving above-mentioned problem, the general thinking is as follows: at least two protective devices 2 which are not electrically wired are arranged at the upper end of the circuit board body 1, when the circuit board body 1 inclines, the protective devices 2 at the upper end firstly touch a machine shell (not shown), and then components (not shown) in the middle are protected; because the protective device 2 can be welded with the butt-joint row socket 3 and the components arranged in the middle, an assembly process is not required to be added on a production line, and the price of the protective device 2 is low, so that the protection cost of the electronic circuit board 100 is reduced.

For better understanding of the above technical solutions, the following detailed descriptions will be provided in conjunction with the drawings and the detailed description of the embodiments.

Referring to fig. 1, a preferred embodiment of an electronic circuit board 100 of an anti-touch casing of the present invention includes:

a circuit board body 1 for carrying the protection device 2, the docking row socket 3 and components (not shown) which need to be electrically wired;

the circuit board comprises at least two protective devices 2 which are not electrically wired, wherein the protective devices 2 are arranged at the upper end of the side surface of the circuit board body 1 and used for providing protection for components arranged in the middle, and the thickness of each protective device 2 is larger than that of each component;

the plurality of butt-joint row sockets 3 are arranged at the lower end of the side face of the circuit board body 1, are downward in butt-joint direction and are used for butt-joint (plugging and unplugging) with other electronic circuit boards 100;
