Abstract
The utility model provides a transition interface card which structurally comprises a printed circuit board (PCB). A male head with a connection terminal and a female head with a terminal slot are arranged on two sides of the PCB, and a control switch and a self detection interface are further arranged on the PCB. Compared with the prior art, the transition interface card has the advantages of being reasonable in design, simple in structure, convenient to user and the like. The transition interface card has functions of free switching cross and direct connection cables and can achieve fast connection.
Description
Technical field
The utility model relates to a kind of adapter, specifically a kind of simple in structure, the translation interface card that can realize no cable connection.
Background technology
The RS-232C consensus standard is EIA (EIA), a kind of serial interface standard of formulation.It is fit to the communication of message transmission rate in 0～20kbit/s scope.RS-232C is most widely used a kind of low-speed serial communication interface in computer and the industrial control field.The main DB-9 Male head connector that adopts in the at present compunication.
The serial ports cable that is used for transmitting the RS232 data can be divided into two kinds by function: direct-connected and intersect.Direct-connected cable generally be used for to prolong computer and equipment, an end 2,3, the corresponding other end of 5pin 2,3,5pin, this cable just is used for prolonging distance; The cable that intersects generally is used for computer and dock with computer, an end 2,3,5pin respectively the corresponding other end 3,2,5pin, namely realize the cable prolongation, realize simultaneously sending and receiving conversion.Because direct-connected cable, to intersect the two ends of cable be the unified regulation of male or female, in therefore using cable terminal, cable function and computer often appear, equipment is inconsistent, and the problem that can't dock is made troubles to use.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of simple in structure, translation interface card is provided.
The technical solution of the utility model realizes in the following manner, this a kind of translation interface card, its structure comprises the PCB circuit board, the both sides of described PCB circuit board are respectively arranged with the male of splicing ear with the female of terminal slot, also are provided with control switch and the interface of testing oneself on this PCB circuit board.
As preferably, described control switch is for being used for direct-connected cable and intersecting the double-point double-throw switch that cable exchanges.After adopting this technical scheme, can realize direct-connected cable and intersect the flexible switching of cable, realize fast intersection and the conversion of direct-connected function of cable.
As preferably, the described interface of testing oneself is the 2Pin contact pin.In this technical scheme, adopt 2pin contact pin connector, when needs form closed loop, during self-test, jumper cap can be inserted on the 2pin contact pin, realize that transmitting-receiving is interconnected, finish self-test function.
In sum, the beneficial effect that compared with prior art produces of the utility model is:
A kind of translation interface jig of the present utility model has the characteristics such as simple in structure, easy to use, novel, the utlity model has and freely switch the function of intersecting with direct-connected cable, can realize the fast interface card of connection, terminal of interface card is male, and one is female, at computer and equipment room when allowing, can omit the serial ports cable, directly use interface card to connect, set up communication, thus reliability and the competitiveness of effective improving product.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is male schematic diagrames of the present utility model.
Accompanying drawing 3 is female schematic diagrames of the present utility model.
Mark in the accompanying drawing represents respectively:
1, male, 2, the PCB circuit board, 3, control switch, 4, the interface of testing oneself, 5, female, 6, splicing ear, 7, terminal slots.
Embodiment
Below in conjunction with accompanying drawing a kind of translation interface card of the present utility model is described in detail below.
Shown in accompanying drawing 1～3, this a kind of translation interface card, its structure comprises PCB circuit board 2, the both sides of described PCB circuit board 2 are respectively arranged with the male 1 of splicing ear 6 with the female 5 of terminal slot 7, this splicing ear 6 is corresponding with terminal slots 7, also is provided with control switch 3 and the interface 4 of testing oneself on this PCB circuit board 2.
The double-point double-throw switch that described control switch 3 exchanges for being used for direct-connected cable and intersection cable.The described interface 4 of testing oneself is the 2Pin contact pin.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
