Description

A kind of jockey

Technical field

The utility model relates to a kind of jockey, relates in particular to a kind of serial terminal interface jockey of electric equipment.

Background technology

At present, the function of electric equipment is more and more, and the various input/output interfaces of expanding on the electric equipment constantly increase, for example network interface, light interface, HDMI, 1394 interfaces, USB interface, video/audio terminal input and output interfaces etc.; Simultaneously, because electric equipment is all developing towards volume miniaturization, compact conformation direction, the space that makes electric equipment to provide is very little, particularly for the electric equipment of moulding, how to make full use of existing casing structure, avoid causing again the new casing of die sinking tool design owing to increasing by one or two terminal interface; In addition, because the pcb board size of electric equipment inside is limited, all terminal interface can not be exported from the rear end to circuit board by all direct cloth; These defectives have become the inevitable technical issues that need to address in the present electric equipment design.

The utility model content

The purpose of this utility model is to provide a kind of jockey of being convenient to the structure miniaturization at above deficiency.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

A kind of jockey, signal input/output device as electric equipment, described electric equipment comprises the processor of processing signals, described jockey comprises a middleware, described middleware one end links to each other with the serial pin of described processor, and the other end links to each other with the input/output interface of electric equipment.

Preferably, described middleware one end links to each other with described processor by the equipment that is flexible coupling, and an end directly links to each other with the input/output interface of described electric equipment.

Preferably, the described equipment that is flexible coupling is lead or optical fiber.

Preferably, described processor is a chip, and described middleware one end is welded to the serial pin of described chip by the equipment that is flexible coupling, and the other end of described middleware directly links to each other with the input/output interface of electric equipment.

Preferably, described middleware is for having the socket of a pin leg (Pin) at least.

Preferably, described middleware is for there being the socket of three pin legs (Pin).

Preferably, described middleware size is less than the input/output interface of described electric equipment.

Preferably, described electric equipment is set-top box or TV or DVD.

Preferably, the input/output interface of described electric equipment is a serial ports.

Preferably, described serial ports places the top of described electric equipment network interface terminal.

In the utility model, input/output interface is owing to link to each other with the processor of electric equipment by middleware, the problem of having avoided interface directly to link to each other with processor, make the space of processor to make full use of, and with the mechanical structure of existing product can be compatible, thereby do not need mechanical structure is offered mould again.

Description of drawings

Accompanying drawing 1 is the circuit theory diagrams of the utility model preferred embodiment;

Accompanying drawing 2 is the structural representation of the utility model preferred embodiment.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail, in the utility model, preferred embodiment adopts set-top box to introduce as specifically being used for, and certainly, also can be TV, DVD or closes other similar electric equipments.

In this preferred embodiment, processor is a max232 chip, but also can be other chip type or components and parts such as PLC controller or CPU; In the present embodiment, adopted the TX of chip and RX pin as the serial pin, but be not limited to this.

As shown in Figure 1,1 is lead, 2 for having the socket of 3 pin legs (Pin), the 3rd pin leg of socket 2 and the 1st pin leg are connected to the output rs 232 serial interface signal TX and the RX of the chip 3 that is arranged in the PCB mainboard respectively by lead 1, it is the chip of max232 that chip 3 herein adopts model, the 2nd pin leg ground connection of socket 2, lead 1 herein is welded direct to the TX and the RX pin of chip 3, pad insulate with heat-shrink tube, socket 2 one ends herein can directly be inserted into (as Fig. 2) on the serial ports, so, socket becomes a serial ports middleware with wire-bonds, thereby make serial ports need not directly be arranged on the PCB mainboard (among the figure for illustrating), and only need to be connected to serial ports, saved the space of PCB mainboard by two pins and the lead outside of chip.

As shown in Figure 2, lead 1 one ends are connected to chip 3, and the other end is connected to socket 2, and socket 2 directly links to each other with serial ports, like this, by the setting of socket 2 and lead 1, make serial ports need not be arranged on the PCB mainboard.In the application of reality, serial ports is disposed in the top of network interface terminal in the electric equipment, and to reduce the electromagnetic radiation of product, the PCB mainboard can be designed to the installation place with the as far as possible close serial ports in position of socket 2 when fabric swatch designs.

More than disclosed only be preferred implementation of the present utility model; but the utility model is not limited thereto; any those skilled in the art can think do not have a creationary variation; and, all should drop in the protection range of the present utility model not breaking away from some improvements and modifications of being done under the utility model principle prerequisite.
