Abstract
The utility model discloses a circuit board fixing groove for preventing signal interference. The circuit board fixing groove for preventing signal interference comprises a groove body (1), wherein a fixing hole (3) is formed at the bottom of the groove body (1); and an interface (2) communicated with the inner part of the groove body (1) is arranged on the side wall of the groove body (1). According to the above structure, the circuit board fixing groove of the utility model can fix the circuit board well and can prevent interference on the circuit caused by external signals.
Description
Technical field
The utility model relates to a kind of holddown groove, specifically is a kind of circuit board holddown groove that anti-stop signal disturbs that is used for.
Background technology
Along with the continuous development of electronic technology, the application of circuit board also more and more widely.At present, general Circuits System tends to relate to a plurality of circuit boards, to realize required function, and the circuit board arrangement mode is generally and directly is fixed on the control panel or in the cabinet, cause circuit board directly to expose in atmosphere, we know, are being mingled with various signals in the atmosphere, will certainly cause circuit board to be disturbed like this, cause circuit to produce signal errors by the external world.
The utility model content
Technical problem to be solved in the utility model is that a kind of circuit board holddown groove that can prevent that stop signal disturbs is provided.
The utility model is achieved through the following technical solutions for the technical solution problem: a kind of circuit board holddown groove that is used for anti-stop signal interference, comprise cell body, described cell body bottom is provided with fixing hole, and the sidewall of cell body is provided with the interface that is connected with cell body inside.The bottom of cell body is used to lay circuit board, and by fixing hole circuit board is fixed.Interface is as the handshaking of circuit board and external circuit.
Also be provided with opening on the sidewall of described cell body.When circuit board is provided with row's pin, can realize connecting by opening, reach the purpose of handshaking.
The end face of described cell body sidewall is provided with screw hole.Be used for and being connected of other equipment, whole holddown groove is fixed on the other system.
Described cell body is a rectangle.Nearly all circuit board integral body all is rectangle, and it mainly is in order to cooperate circuit board that cell body adopts rectangle.
Described cell body is made of aluminum.Aluminium has good shield effectiveness, can prevent the outer signals interference so well.
The utility model compared with prior art has the following advantages and beneficial effect: the utility model adopts the aluminium trough body structure of rectangle that circuit board is fixed; aluminium has good shielding action; the protective circuit plate is avoided the outer signals interference well; simultaneously, circuit board can be realized carrying out handshaking with external equipment by the interface, the opening that are provided with on the cell body.
