Description

Crystal head Connection Card buckle device

Technical field

The utility model relates to a kind of crystal head Connection Card buckle device of operating case on grafting cover, and when especially operating case loading, taking-up, crystal head can not along the connecting fastener device of grafting direction vibration .

Background technology

In the middle of the power electronic equipments such as existing frequency converter, server, guidance panel data line interface generally uses RJ-45 crystal head mode, and guidance panel need consider Long-distance Control, can adopt the operating case form of movement.For the move operation box being fixed on cover or cabinet door, ensure the operability that its crystal head connects and reliability particularly important.If adopt non-standard crystal head, cost is high and connection may not be reliable; If adopt standard water crystal-tipped, how to be fixed on by crystal head easily on cover or cabinet door is a problem.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of electrical connector, do not change standard water crystal-tipped and crystal headstock, when the hand-held operating case that crystal headstock is housed loads cover or cabinet door, crystal head can not be shifted and retreat and affect operating case installation, when taking out operating case, crystal head is fixed on cover or cabinet door and does not extract with operating case.

For solving the problems of the technologies described above, the utility model adopts crystal head Connection Card buckle structure, the operating case on cover is sunken to for grafting power electronic equipment, this electrical connector to be coated and fixed crystal head by fastener, the cover back side is caught on a pair clamp, when operating case loads, the crystal head of the crystal headstock insertion machine lid at the operating case back side.Scratch its upper end when operating case takes out and turn an angle, fastener withstands cover back side convex closure, and there is certain interval fastener clamp and convex closure bayonet socket both sides, control crystal head and have small sideshake, compensate grafting error, but crystal head along the upper and lower vibration in grafting direction, can not ensure the smooth and easy taking-up of operating case.

As further improvement of the utility model, cover arranges pit and holds the operating case loaded, pit bottom convex closure holds the crystal headstock inserted, in other words with on the rectangular thin-wall pit of operating case adaptation, the square convex closure of thin-walled of reshaping one and crystal headstock adaptation, from the cover back side, bayonet socket is offered in convex closure two side, and crystal head head is connected with the crystal headstock on operating case through irregularly-shaped hole bottom convex closure.

Improve as another kind of the present utility model, a pair clamp is extended in the relative both sides of fastener, opposite side stub catches on crystal head step, crystal head another side shell fragment is depressed and is filled in fastener intermediate cavity, and then crystal head and fastener are combined into one, crystal head crimping winding displacement is drawn from fastener cavity bottom, and crystal head can have small vibration in the plugging direction.Fastener clamp is narrow and thin, utilizes the strain along the convex hook direction of head to carry out locating fastener, adopts plastic one-body molded.

The fastener location of the utility model crystal head Connection Card buckle device is reliable, rational in infrastructure, easy to use.During Long-distance Control, only need make the lengthening winding displacement of communication that two ends are crimped with standard water crystal-tipped, lengthen the crystal headstock on the inner printed circuit board of winding displacement of communication one end crystal head insertion power electronic equipment such as frequency converter, server, the other end inserts the crystal headstock being fixed on the operating case back side of far-end, can realize Long-distance Control.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Fig. 1 is the three-dimensional exploded view adopting the utility model crystal head Connection Card buckle device.

Fig. 2 is the schematic perspective view that the Connection Card of crystal head shown in Fig. 1 buckle device operating case loads cover.

Fig. 3 is the schematic perspective view that the Connection Card of crystal head shown in Fig. 1 buckle device operating case takes out cover.

Fig. 4 is the schematic perspective view of the Connection Card of crystal head shown in Fig. 1 buckle device fastener.

Fig. 5 is the schematic perspective view of the Connection Card of crystal head shown in Fig. 1 buckle device fastener.

Embodiment

Fig. 1 shows the utility model crystal head Connection Card buckle device, and this device is plastic products, comprises the fastener 1 of fixing crystal head 2, the crystal headstock 5 of its crystal head 2 one end on cover 3 grafting operating case 4.The bayonet socket 311 that cover 3 back side convex closure 31 is offered is two side square hole, and plastic mould core-extracting can realize, and offers irregularly-shaped hole and be convenient to crystal head 2 head and pass in the middle of convex closure 31, and crystal headstock 5 to be fixed in operating case 4 on printed circuit board.

Fig. 2 and Fig. 3 shows the using state that operating case 4 loads and takes out cover 3, the square convex closure 31 in the little thin-walled pit back side on cover 3 rectangular thin-wall pit, visible two bayonet sockets 311 and crystal head 2 head exposed; Because operating case 4 is sunken to cover 3, scratch operating case 4 top with finger through cover 3 semi-circle pockets during taking-up, when operating case 4 forwards certain angle in the direction of the arrow, crystal head 2 and crystal headstock 5 junction depart from, operating case 4 departs from cover 3, and crystal head 2 is still fixed in cover 3 pit.

Adopt the utility model bayonet unit, illustrate from Fig. 4 and Fig. 5 different directions, first the stub of fastener 1 11 and shell fragment 21 are locked crystal head 2 from two sides combination, crimping winding displacement 6 passes bottom fastener 1.Because clamp 12 Width produces certain degree of freedom relative to bayonet socket 311 liang of side clearances, when operating case 4 loads cover 3, in Fig. 1, crystal head 2 can aim at the crystal headstock 5 at grafting object-operating case 4 back side by centering; When operating case 4 takes out cover 3, because convex closure 31 end face is equal with the h size that clamp in Fig. 5 12 hooks plane separation fastener 1 end face apart from the h size of bayonet socket 311 in Fig. 1, clamp 12 avoids vibration on bayonet socket 311, ensure that the reliability of device.Operating case 4 be connected with cover 3 buckle herein describe scope.

The foregoing is only preferred embodiment of the present utility model; but not any pro forma restriction is done to the utility model; those skilled in the art can impose various equivalent change and improvement on the basis of above-described embodiment; all equivalent variations of doing in right or modification, all should fall within protection range of the present utility model.
