Abstract
The utility model provides a novel needle quitting device which is provided with a shell and a push rod, wherein the shell consists of a plastic outer sleeve and a metal embedding piece; one end of the metal embedding piece is accommodated in the plastic outer sleeve, and the metal embedding piece and the plastic outer sleeve are cast into a whole; the other end of the metal embedding piece is suspended; step through holes are formed in the plastic outer sleeve and the metal embedding piece; threads are formed on two ends of the push rod; the thread on one end of the push rod is riveted with a riveting column I, penetrates through the step through hole of the metal embedding piece and pushes against one end of a step I of the step through hole; the other end of the push rod penetrates through the step through hole and is riveted with a riveting column II; an elastic device is arranged on the inner end face of the riveting column II and is sleeved on the push rod; and the other end of the elastic device pushes against the end face of a step II. The novel needle quitting device is simple in structure and convenient to use; a contact piece can be successfully quit from an insulation body; after the contact piece is quit, the insulation body cannot be damaged; and the novel needle quitting device has extremely high practical value.
Description
Technical field
The utility model relates to a kind of novel pin remover, is applicable to large electric current industrial connector is inserted the dial-out application of the contact in insulator.
Background technology
The contact of industrial connector and the fixed form of insulator generally are divided into two kinds, and the one, utilize two insulators to limit fixed contact therefor; The 2nd, utilize the resilience gear ring of " hangnail " structure of turning up to come the screens fixed contact therefor.In actual use, adopt the installation method of " hangnail " structure to be widely used because it is easy to operate, remove easily unlike two insulators are fixing after adopting this kind method contact to be installed to insulator, make troubles for the maintain and replace contact, therefore need special equipment to coordinate.
The utility model content
The technical problem that the utility model solves: a kind of novel pin remover is provided, by push rod, contact is withdrawed from from insulator, and can not damage insulator after withdrawing from, simple in structure, easy to use.
the technical solution adopted in the utility model: novel pin remover, have housing and push rod, described housing is made of plastic wrapper and metal insert, described metal insert one end is included in plastic wrapper and both water and are solidified as a whole, the metal insert other end is unsettled, be shaped with step through-hole in described plastic wrapper and metal insert, described push rod two ends all are shaped with screw thread, the screw thread of push rod one end and riveting post I screw and pass from the step through-hole of metal insert step I one end that is against step through-hole, the push rod other end passes step through-hole and screws with riveting post II, described riveting post II inner face is provided with elastic device, described elastic device is sleeved on push rod and its other end is pushed against on step II end face.
Wherein, the external diameter of described metal insert is less than the polarity hole of insulator, and the large nose end diameter of the step through-hole of metal insert is greater than the external diameter of contact.
Further, described elastic device is spring, and described spring housing is contained on push rod, and spring one end pushes against riveting post II inner face, and the spring other end is pushed against on step II end face.
Further, be shaped with anti-slip veins on described plastic wrapper excircle.
The utility model is compared with prior art simple in structure, and is easy to use, solved the problem that contact withdraws from from insulator body smoothly, and can not damage insulator after withdrawing from, and has very high practical value.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model uses view.
Embodiment
Below in conjunction with accompanying drawing 1,2, a kind of embodiment of the present utility model is described.
Novel pin remover, have housing 1 and push rod 2, described housing 1 is made of plastic wrapper 3 and metal insert 4, described metal insert 4 one ends are included in plastic wrapper 3 and both water and are solidified as a whole, metal insert 4 other ends are unsettled, be shaped with step through-hole 5 in described plastic wrapper 3 and metal insert 4, the step through-hole 5 that is shaped with on described plastic wrapper 3 guarantees solid and reliable to increase glue fixing structure frictional force.Be shaped with anti-slip veins on described plastic wrapper 3 excircles.Concrete, the external diameter of described metal insert 4 is less than the polarity hole 13 of insulator 12, in order to go deep into when shirking contact 14 in the polarity hole 13 of insulator 12, large nose end 7 diameters of the step through-hole 5 of metal insert 4 are greater than the external diameter of contact 14, in order to tighten up the hangnail structural elasticity gear ring on contact 14.Described push rod 2 two ends all are shaped with screw thread, the screw thread of push rod 2 one ends and riveting post I 6 screw and pass from the step through-hole 5 of metal insert 4 step I 8 one ends that are against step through-hole 5, push rod 2 other ends pass step through-hole 5 and screw with riveting post II 9, described riveting post II 9 inner faces are provided with elastic device, concrete, described elastic device is spring 11, described spring 11 is sleeved on push rod 2, spring 11 1 ends push against riveting post II 9 inner faces, and spring 11 other ends are pushed against on step II 10 end faces.Described elastic device is sleeved on push rod 2 and its other end is pushed against on step II 10 end faces.
During work, with the positive hangnail structural elasticity gear ring that is stuck in " turning up " on insulator 12 on contact 14 of aiming at of the large nose end 7 of pin remover, and push hard at the bottom of the hole in polarity hole 13 till can not push away again, at this moment, the hangnail structural elasticity gear ring that the large nose end 7 of the metal insert 4 of pin remover will " turn up " tightens up, and then contact 14 can be released from insulator 12 with hand push rod 2.
Above-described embodiment is preferred embodiment of the present utility model, is not to limit the utility model practical range, thus all equivalence variations of being done with the described content of the utility model claim, within all should being included in the utility model claim scope.
