Abstract

The utility model relates to a fixing frame for a computer connector. The fixing frame is erected on an upper and a lower plug-in sockets of a computer connector. A soleplate of the fixing frame for a computer connector is provided with an n-shaped scarfing member. The scarfing member is fixed on a printed circuit board to cause a connector terminal to be steady. The fixing frame for a computer connector is characterized in that the top of the soleplate of the fixing frame is protruded with a scarfing block. The n-shaped scarfing member is provided with a flute corresponding to the scarfing block. The scarfing block and the flute are mutually tightly tabled by press working. When the scarfing member is inserted in the printed circuit board, the fixing frame does not offset and fall off from the scarfing member. The connector can be steadily installed and can conduct inserting work.

Description

The computer connector fixed mount

The utility model relates to a kind of computer connector fixed mount, belongs to computer and accessory device field.

Computer connector is installed in the rear side of host computer, and peripheral hardwares such as keyboard, display are used to peg graft; For easy for installation, connector all is the rear side that mode arranged side by side up and down is arranged on host computer.Common televisor, combination audio or other digital data transmission equipment also have similar connector, all belong to same series products with the utility model.

Existing computer connector structure as described in Figure 1, every group of connector all includes: go up the following plug socket of plug socket 10,20, a Connection Block 30 and a left and right fixed 40 for one; Wherein, the bottom of upper and lower plug socket 10,20 is respectively equipped with a plurality of terminals 101,102 of vertical direction.Because last plug socket 10 is positioned at the top, so need earlier its terminal 101 to be plugged on the Connection Block 30, terminal 301 by Connection Block 30 aligns with the terminal 201 of following plug socket 20, then go up plug socket 10 just can with following socket 20 together with in horizontal direction printed circuit board (PCB) (end illustrates among the figure) grafting conducting.Cause loose contact, people to design fixed mount 40 in order to prevent upper and lower plug socket 10,20 and Connection Block 30 from skew being arranged with circuit board plug-and-socket the time and be fixed on upper and lower plug socket 10,20 and the printed circuit board (PCB), to make things convenient for the grafting operation of connector.

This fixed mount 40 as shown in the figure, it is a sheet metal that is " L " type, its side plate 401 is provided with spacing hole 402, be used for and, following plug socket 10,20 is fixing, its base plate 403 digs and is provided with fixed orifice 404, make " Jiong " shape interlocking part 405 can fix on it, should " Jiong " shape interlocking part 405 tops be stator 451, the socle that extend downwards both sides is an inserted terminal 452, folded solid on fixed mount base plate 403 by stator 451, make inserted terminal 452 pass fixed orifice 404 back and extend downwards, just can with the terminal 201 of above-mentioned plug socket 20 down and Connection Block 30,301 rabbet simultaneously on the PC plate, can prevent terminal 201,301 off normals are loosening.Therefore, the basic function of fixed mount is fixed upper and lower plug socket 10,20 exactly, and the terminal 201,301 that makes down plug socket 20 and Connection Block 30 does not have the loosening problem of skew when being plugged into printed circuit board (PCB).Be present product, can not bring into play its due effect.Mainly be because " Jiong " shape is rabbeted the affixed of part 405 and " L " shape fixed mount 40 main bodys; be that the base plate 403 of stator 451 and fixed mount 40 by interlocking part 405 tops splices and forms; for easy to process; existing product is to adopt spot welder fixing at stator 451 and base plate 403 superimposed laggard spot weldings; because the machining precision of spot welder is not accurate enough; therefore put postwelding stator 451 and often have and come off or off normal, make fixed mount 40 can't realize its basic function.

The purpose of this utility model provides a kind of computer connector fixed mount, by closely cooperating of built-in brick and groove, fixed mount and interlocking part are fixed, and when the interlocking part is rabbeted on printed circuit board (PCB), be not easy to take place off normal, thereby make connector more firm with engaging of printed circuit board (PCB), the situation that does not have loose contact takes place.

The utility model is achieved in that and is L-shaped sheet metal, its side plate is provided with spacing hole, use and on, following plug socket is fixed, its base plate is provided with fixed orifice, the bottom inserted terminal that makes " Jiong " shape interlocking part can cover and intercalation on the brain printing circuit board, this interlocking part top is a stator, folded up and down solid with the base plate of fixed mount, it is characterized in that: the base top distal process of this fixed mount is provided with a built-in brick, the position that the stator of interlocking part corresponds to built-in brick is provided with groove, and the size of groove is equal to or slightly less than built-in brick just, utilize punch process to make built-in brick embed groove, thereby and make the interlocking part take this to fix with fixed mount with groove is closely chimeric mutually.

Design feature of the present utility model is by built-in brick 431 and groove 453 location, and utilize Sheet Metal Forming Technology to make it to closely cooperate, fixed mount and interlocking part are fixed, and the interlocking part is when the intercalation printed circuit board (PCB), be not easy off normal, make connector more firm with engaging of printed circuit board (PCB), the situation that does not have loose contact takes place, and helps the operation that patches of connector.

Fig. 1 is a three-dimensional exploded view of the present utility model.

Fig. 2, Fig. 3 are respectively fixed mount of the present utility model and the combination synoptic diagram of rabbeting part.

Referring to Fig. 1, Fig. 2, Fig. 3, shape of the present utility model is identical with general fixed mount, for being

The sheet metal of " L " shape, its side plate 401 is provided with spacing hole 402, use and on, following plug socket 10,20 is fixing, its base plate 403 is provided with fixed orifice 404, the bottom inserted terminal 452 that makes " Jiong " shape interlocking part 405 can cover and intercalation on the brain printing circuit board, the socle that extend downwards stator 451 both sides at these interlocking part 405 tops is the inserted terminal that is ratchet-shaped, folded up and down solid by the stator 451 and the base plate 403 of fixed mount 40, making inserted terminal 452 pass fixed orifice 404 backs extends downwards, can with the terminal 201 of above-mentioned down plug socket 20 and Connection Block 30,301 intercalations simultaneously are circuit boards in printing, and utilize inserted terminal 452 to embed printed circuit board (PCB)s and fix.

Principal character of the present utility model is: a built-in brick 431 is equipped with on base plate 403 tops of this fixed mount 40, the position that the stator 451 of interlocking part 405 corresponds to built-in brick 431 is provided with groove 453, and the size of groove 453 is equal to or slightly less than built-in brick 431 just, when the inserted terminal 452 of rabbeting part 405 passes base plate 403, and groove 453 lucky and built-in brick 431 contrapositions, utilize punch process, can make built-in brick 431 embed groove 453, and closely cooperate with groove 453, interlocking part 405 can be fixing with fixed mount 40 by this.

The utility model architectural feature is to abandon in the prior art to utilize welding fixing, and fixed mount 40 and interlocking part 405 location structures not itself cause interlocking part 405 to come off easily, and add the significant deficiency that also easily causes off normal man-hour.The fundamental purpose that the utility model is provided with built-in brick 431 and groove 453 makes fixed mount 40 and interlocking part 405 itself have location structure exactly, avoids relying on fully the shortcoming of job operation location by this.Therefore, built-in brick 431 can be circular with the shape of groove 453 in the utility model, also can be the polygon of quadrangle, sexangle or other shapes.
