Description

The pin of computer connector is block set fixedly

Technical field

The pin that the utility model relates to a kind of computer connector is block set fixedly, refers on a kind of pin of connector fixedly block set of cover intrinsic especially, this fixedly block set can protect the scolding tin of pin on motherboard, and can prevent the pin bending or rupture.

Background technology

General traditional type is applicable to the connector of industrial computer, as shown in Figure 6, substantially (spring) type does not install the connector 100 of other function cards additional, the pin 101 of its international standards length passes the through hole 201 of motherboard 200 earlier, and then in the mode of spot welding, with flatiron tin 300 is melted in the junction of through hole 201 with pin 101, and tin 300 melts the shape that is attached to the junction and is in harmony the most with the volcano shape and works as, and can make through hole 201 and pin 10 not have the facts generation of loose contacts such as cold welding or empty weldering; If but connector 100 has the above pin 101 of two rows, welds pin 101 in the spot welding mode, be obviously a kind of time-consuming, take a lot of work, and be highly difficult work; For example: connector 100 is the some branch connecting pins 101 of four rows, the pin 101 in its two outside welds easily, but the just very difficult weldering of middle two rows' pin 101, also can't pass the work that weld in the pin gap if flatiron is excessive, and the high temperature of flatiron might influence the tin 300 that has before welded, cause cold welding indirectly, the situation of empty weldering or 101 short circuits of pin takes place.

As shown in Figure 7, these lowermost end connector 100 desires are upwards pegged graft other connectors 100 ' with the multiple additional specific function clamp (PC plate) 400 of connecting, make specific uses such as additional 2D of being of computer or 3D, the pin 101 ' of each connector 100 ' is planted respectively and is connected in series another connector 100 ' again behind the clamp 400, because the length of this pin 101 ' is the specification of international standard, when its long pin 101 ' runs through specific function clamp 400 and pegs graft another group connector 100 ', on, surely can expose pin 101 ' partly between the lower connector 100 ', when the unlatching computer casing is checked or is keeped in repair computer (general power supply is not all closed), some findings such as screw easily touch this pin 101 ' that exposes and cause short circuit phenomenon, pin 101 ' takes place sometimes touch the metal tools (as bottle opener) of maintenance computer usefulness that personnel hold and produce short circuit phenomenon; In addition, because pin 101,101 ' bending, even can influence tin 300 and melt the solid welding conjugation that is attached to motherboard 200 through holes 201 or clamp 400 and pin 101,101 ' junction, thereby cause the situation of pin 101,101 ' fracture to take place.

Summary of the invention

The pin that the purpose of this utility model provides a kind of computer connector is block set fixedly; it is main after the pin of connector body passes motherboard and scolding tin; pin can run through a fixedly perforation of block set again; this fixed cover seat is fixed in the junction of motherboard through hole and pin; therefore except protecting scolding tin is not destroyed; can make pin be exposed at the part crested in the outside separately again, make the pin bearing stress stronger, be difficult for bending and fracture.

The pin that another purpose of the present utility model provides a kind of computer connector is block set fixedly, when the connector body on the lowermost end motherboard is upwards pegged graft some connector bodies and specific function clamp, fixedly block set can not cover in the pin that is exposed between the upper and lower connector body fully, preventing to keep in repair the touching of dropping because of carelessness of findings such as instrument touching pin that computer held or screw, thereby can avoid producing the situation of short circuit generation; Member wherein of the present utility model is simple but practical effect is quite huge, in constantly flourish computer technology industry, is the high creation of a surcharge.

For achieving the above object, the utility model is taked following design proposal: the pin of this computer connector fixedly block set be provided with one the top opening housing, the bottom of housing is provided with a plurality of perforation, its position is corresponding one by one with a plurality of pins of computer connector, and hole dimension is identical with the pin sectional dimension or big slightly.

Effect of the present utility model is to be illustrated in the embodiment paragraph.

Embodiment

As shown in Figure 1-Figure 3, the utility model is made generally basic (spring) type industrial computer connector structure (not additional special function card), be provided with the pin 11 formed lead area of some marshallings in general connector body 1 front end, this pin 11 is the junction that can run through through hole 21 with the pin 11 of some marshallings on the motherboard 2 respectively, to weld pin 11 on motherboard 2.

Some pins 11 of connector body 1 are behind through hole that runs through motherboard 2 and scolding tin, run through fixedly some perforation 41 of block set 4 of bottom more respectively, thereby make fixing block set 4 be fixed in the junction (as Fig. 3) of motherboard 2 below through holes 21 and pin 11, and scolding tin 3 is partly covered in fully, therefore except can protecting scolding tin 3 not to be destroyed or coming off, fixedly block set 4 also can be firmly solid near motherboard 2 parts cover with pin 11, thereby pin 11 is leaked outside partly shorten, to strengthen the stress intensity of long direct pin 11, prevent pin bending or fracture;

Fixedly block set 4, it is monolateral opening housing up, be that to be provided with some perforation 41 corresponding with the through hole 21 of motherboard 2 on its base plate, this perforation 41 can be square hole, square cross-sectional shape with coupling pin 11, in the time of so in pin 11 is inserted solid perforation 41 in fixing block set 4, but not must with viscose glue or riveting button just build-in locate.

As shown in Figure 4, the utility model another kind is the connector body 5 of T font, the also T-shaped lead area of the pin 51 of its bottom, run through the through hole 21 of motherboard 2 after, run through the fixedly perforation 71 of block set 7 of T font again.Thereby the opening of this cover for seat and bottom are T-shaped.

As shown in Figure 5, the connector 5 of lowermost end other connector bodies 5 ' of upwards pegging graft, when making computer be promoted as specific functions such as 2D or 3D with the multiple additional specific function plate (PC plate) 6 of connecting, the pin 51 of each additional connector body 5 ' bottom can be planted respectively and be connected in series another connector body 5 ' again behind the clamp (PC plate) 6 of a specific function, on being somebody's turn to do, lower connector body 5 ' is pegged graft and is become one, the part pin 51 that is exposed therebetween can mat fixing being nested with of block set 7 and pin 51 is covered fully, thereby can prevent that the maintenance computer personnel are in maintenance process, employed metal tools (as bottle opener) or finding (as the screw) touching of dropping because of carelessness are to avoid producing the phenomenon of short circuit.

In sum; the pin of the utility model computer connector is block set fixedly; utilize fixed cover seat generally basic (spring) type that is fixed in of an innovation to run through motherboard and on the pin of scolding tin; thereby can protect scolding tin to be fixed on motherboard through hole and pin junction; and can prevent directly to pin bending or fracture; its practical effect is when unquestionable, and the utility model is never made the city know or seen other books and periodicals documents.
