Commutator

Abstract

The invention discloses a commutator. A first electrical connection specification of the commutator can be fixed on a first circuit board and connected to a second circuit board through a second electrical connection specification; and the second circuit board can be expanded to the first circuit board through the commutator after the second circuit board is electrically connected to the first circuit board. Therefore, the technical efficiency of function expansion of circuit boards among different electrical connection specifications can be achieved.

Description

technical field [0001] The invention relates to an adapter, in particular to an adapter for internal conversion of different electrical connection specifications between a first circuit board and a second circuit board. Background technique [0002] Industrial Personal Computer (IPC) is a computer specially used in the industry. Compared with the personal computer (PC) used by ordinary consumers, industrial computer is actually a relatively strong enhanced personal computer. Used as an industrial controller, it meets the reliability requirements in the industrial environment. [0003] Due to the reliable performance, rich software and low price of industrial computers, industrial computers have suddenly emerged in the computer industry, and their applications are becoming more and more extensive. At present, industrial computers have been widely used in communication, industrial automation, medical treatment, environmental protection, aerospace and all aspects of human life...

Problems solved by technology

[0005] However, in terms of the second circuit board with some special input / output specifications, often the second circuit board with this special input / output specification cannot directly match the existing input / output specifications of the first circuit board in the industrial computer. This also causes the problem of adding a second circuit board with special input / output specifications to the first circuit board in the industrial computer. As far as the prior art is concerned, most of them are the input / output specifications of the first circuit board in the industrial computer. Each input / output pin is connected to each input / output pin of the second circuit board with special input / output specifications one by one in the way of electrical connection of the line, so as to achieve the second circuit board with special input / output specifications added to the industrial computer

[0006] However, in this way, it needs to be done manually, which is not conducive to mass production in the industry. In addition, this way of electrically connecting the circuit board and the first circuit board of the industrial computer Either there is no way to fix the two circuit boards, or it is necessary to additionally fix the first circuit board and the second circuit board, which also causes the problem of adding the second circuit board to the first circuit board of the industrial computer. Of course, The most fundamental solution is to directly redesign the first circuit board of the industrial computer, so that the industrial computer can provide the input / output specification interface of the second circuit board, but the customized design of this additional function will make the development of the industrial computer The sharp increase in cost is obviously not a good solution

[0007] To sum up, it can be seen that the electrical connection specifications between the first circuit board and the second circuit board of industrial computers have long existed in the prior art, which makes it difficult to form an electrical connection between the first circuit board and the second circuit board. , so it is necessary to propose improved technical means to solve this problem
