Abstract

The utility model provides a binding post, comprising a door-shaped fixed part, a swirling member, a screw, a compression spring and a washer. The upper end surface of the door-shaped fixed part is provided with a first screw hole; the swirling member is provided with a second screw hole; the swirling member, the compression spring and the washer are all arranged in the door-shaped fixed part; the screw rod of the screw traverses the first screw hole to be in connection with the compression spring and the washer, and traverses the second screw hole of the swirling member; the screw rod traversing the second screw hole is a screw rod flat part. According to the utility model, when the binding post is welded to a PCB, the PIN on the F head can be mounted and dismounted through fastening and loosening the screw of the binding post; the mounting of the F head is more convenient and faster, and the PCB can be removed from a housing in a more convenient way.

Description

A kind of binding post

Technical field

The utility model relates to optical transmission device technical field, relates in particular to a kind of F head to be fixed on to the binding post on printed circuit.

Background technology

The optical transmission devices such as existing optical workstation, optical receiver, in its structure, be all roughly hard shell and the pcb board (printed circuit board (PCB)) that is arranged on enclosure interior, and at the side opening of housing, being provided with the perforate of external F head, the PIN pin of F head is welded on pcb board through after perforate.Therefore when assembling is produced, welding procedure and operating personnel's technical merit are had higher requirements, and after having assembled, while taking out the pcb board of enclosure interior, need use flatiron fusing PIN pin is connected with pcb board, pcb board could be taken out, very inconvenient, therefore need badly F head is improved with the structure that is connected of pcb board.

Summary of the invention

The purpose of this utility model is to provide a kind of without the PIN pin of F head is welded on pcb board, and assembly and disassembly are binding post structure very easily all.

The utility model is that the technical scheme that its technical problem of solution adopts is:

A kind of binding post, it is characterized in that: comprised door type fixture, rotating part, screw, Compress Spring and packing ring, in door type fixture upper surface, offer screw one, on rotating part, offer screw two, described rotating part, it is inner that Compress Spring and packing ring are all installed in a type fixture, the screw rod of screw is through the rear cross-under Compress Spring of screw one and packing ring, pass again the screw two of rotating part, the screw portion that passes screw two is made as plat part, i.e. door type fixture, Compress Spring, packing ring and rotating part are fastened between screw terminal and screw rod plat part, therefore screw can not screw out from screw one and screw two, whole binding post becomes non-removable integral body.During use, binding post is welded to relevant position on pcb board, the PIN pin of F head is inserted into the space between a type fixture and rotating part, then use screwdriver holding screw, space between a type fixture upper surface and rotating part is dwindled, thereby PIN pin is fastened between a type fixture and rotating part; While taking out F, use screwdriver Unscrewed screw, under the effect of Compress Spring resilience force, struts rotating part and a door type fixture gradually, and after the distance between rotating part and door type fixture upper surface becomes greatly, PIN pin can be extracted.

As preferably, the height of described packing ring is slightly less than the diameter of PIN pin, and fixedly during PIN pin, packing ring can limit screw excessive tightness and cause the distortion of PIN pin.

As preferably, described screw one is arranged on slightly on the door type fixture upper surface near door type fixture side.

As preferably, described rotating part is the strip flat structure of round end one end, one end tack, and screw two is opened near on the position of rotating part round end.Because rotating part is subject to the restriction of screw one position, screw two is also near a wherein side for type fixture, during Unscrewed screw, the butt end of rotating part, under the drive of screw, also starts rotation, but when rotating to a type fixture side, eccentric setting due to screw two, rotating part just can not continue rotation, now continues Unscrewed screw, and rotating part could become large with the distance of door type fixture upper surface.

As preferably, the spiro rod length between described screw terminal and screw rod plat part is slightly larger than a type fixture upper surface thickness, PIN pin diameter and rotating part three thickness sum, could meet so the loosening and fastening needs of PIN pin.

The utility model has the advantage of, after binding post is welded on pcb board, the PIN pin of F head can be realized by the screw of fastening and loosening binding post the installation and removal of PIN pin, F head easier for installation quick, and it is also convenient from housing, to take out pcb board.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach object with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.

In conjunction with Fig. 1, Fig. 2 and Fig. 3, the utility model is welded on the side of pcb board 7, pcb board 7 is installed in housing 8, the side opening of housing 8 is provided with perforate 81, the PIN pin 61 of F 6 is connected on binding post through perforate, the utility model binding post has comprised door type fixture 1, rotating part 2, screw 5, Compress Spring 4 and packing ring 3, in door type fixture upper surface 12, offer screw 1, screw 1 is arranged on the door type fixture upper surface 12 of slightly close door type fixture the first side 11, on rotating part 2, offer screw 2 21, rotating part 2, Compress Spring 4 and packing ring 3 are all installed in type fixture 1 inside, the screw rod of screw 5 (not marking in figure) is through the rear cross-under Compress Spring 4 of screw 1 and packing ring 3, pass again the screw 2 21 of rotating part 2, screw rod (not marking in the figure) part that passes screw 2 21 is made as flat, for screw rod plat part 52.Door type fixture 1, Compress Spring 4, packing ring 3 and rotating part 2 are fastened between screw terminal 51 and screw rod plat part 52, so screw 5 can not screw out from screw 1 and screw 2 21, and whole binding post becomes non-removable integral body.The height of packing ring 3 is slightly less than the diameter of PIN pin 61, and fixedly during PIN pin 61, packing ring 3 can limit screw 5 excessive tightness and cause 61 distortion of PIN pin.Spiro rod length between screw terminal 51 and screw rod plat part 52 is slightly larger than type fixture upper surface 12 thickness, PIN pin 61 diameters and rotating part 2 three's thickness sums, could meet so the loosening and fastening needs of PIN pin 61.Rotating part 2 is the strip flat structure of round end one end, one end tack, and screw 2 21 is opened near on the position of rotating part round end (not marking in figure).

During use, binding post is welded to relevant position on pcb board 7, the PIN pin 61 of F 6 is inserted into the space between a type fixture 1 and rotating part 2, then use screwdriver holding screw 5, space between a type fixture upper surface 12 and rotating part 2 is dwindled, thereby PIN pin 61 is fastened between a type fixture upper surface 12 and rotating part 2; Take out F 6 o'clock, use screwdriver Unscrewed screw 5, rotating part butt end 22, under the drive of screw 5, also starts rotation, but when rotating to type fixture first side 11, due to the eccentric setting of screw 2 21, rotating part 2 just can not continue rotation, now continues Unscrewed screw 5, under the effect of Compress Spring 4 resilience forces, strut gradually rotating part 2 and door type fixture 1, after the distance between rotating part 2 and door type fixture upper surface 12 becomes greatly, PIN pin 61 can be extracted.
