Technical field
The utility model relates to a kind of terminal, and more particularly, it relates to the female all insulation joint of a kind of bullet shaped.
Background technology
Terminal is the connector of conduction use or conducting electrical signals.
At present, the female all insulation joint of bullet shaped on market, it comprises joint body, the head of joint body is set to columnar socket part (rolling into tubular by sheet material), for being socketed the public pre insulated joint of bullet shaped, the afterbody of joint body is set to columnar thread jamming part, and for clamping wire, the external overall of joint body is socketed with insulating case.The female all insulation joint of this bullet shaped, usually with suitable bullet shaped public pre insulated joint with the use of, for improving the steadiness that the female all insulation joint of the male pre insulated joint of bullet shaped and bullet shaped is connected, the buckling groove 31 of annular is often set in the grafting part 3 of the public pre insulated joint of bullet shaped, as shown in Figure 3, the buckling groove 31 of annular is arranged on the middle part of grafting part 3, correspondingly, for coordinating clamping buckling groove 3, need to arrange stuck point (as stamped out a salient point on the wall body of socket part) on the socket part of the female all insulation joint of bullet shaped, but common stuck point, be connected with the wall body one of stuck point peripheral part, elastic deformation ability is poor, be not suitable for the operation of grafting frequently, and the clamping power of a stuck point to buckling groove is uneven, clamping scarce capacity, make the snap effect of the female all insulation joint of bullet shaped and bullet shaped male pre insulated joint poor.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the female all insulation joint of bullet shaped providing a kind of snap effect good.
For achieving the above object, the utility model provides following technical scheme: the female all insulation joint of a kind of bullet shaped, comprise joint body, the head of described joint body is set to columnar socket part, the afterbody of described joint body is set to columnar thread jamming part, the outer cover of described joint body is connected to insulating case, it is the hollow-out parts of bar shaped that the wall body of described socket part is provided with when launching in socket part, described hollow-out parts is c-shaped in the projection view of socket part axis, described hollow-out parts place plane orthogonal in socket part axially, the C shape snap ring that shape is with it suitable is provided with in described hollow-out parts, the two ends of described C shape snap ring are fixedly connected with the two ends of hollow-out parts, described C shape snap ring relative socket part inwall is in arranging to socket part central axial direction convex shape.
By adopting technique scheme, when the grafting part of public for bullet shaped pre insulated joint is plugged in socket part, C shape snap ring is connected in the buckling groove in grafting part, surrounds buckling groove, compare the interface arrangment of button type in circumferential portion, clamping scope is large, clamping power evenly, and C shape snap ring only has two ends to be connected with two end winding support of hollow-out parts, and its upper and lower dual-side and socket part are without annexation, better elastic deformation ability is provided, is applicable to grafting operation frequently.
The utility model is set to further: described C shape snap ring in the shape of cross section of socket part axis be the C shape of opening central axis dorsad.
By adopting technique scheme, C shape snap ring is c-shaped, provides the clamping transition face of arc in inside, socket part, make C shape snap ring more easily with buckling groove clamping or disengaging, grafting is operated and more easily completes.
The utility model is set to further: described insulating case is made up of PVC or nylon.
By adopting technique scheme, PVC or nylon material, good insulating, not easily by acid, caustic corrosion, and strong to hot tolerance, stable performance, provides reliable insulation protection.

Embodiment
Referring to figs. 1 through Fig. 2, the female all insulation plug embodiments of the utility model bullet shaped is described further.
The female all insulation joint of a kind of bullet shaped, comprise joint body 1, the head of described joint body 1 is set to columnar socket part 11, the afterbody of described joint body 1 is set to columnar thread jamming part 12, the outer cover of described joint body 1 is connected to insulating case 2, it is the hollow-out parts 111 of bar shaped that the wall body of described socket part 11 was provided with when socket part 11 is launched, described hollow-out parts 111 is c-shaped in the projection view of socket part 11 axis, described hollow-out parts 111 place plane orthogonal in socket part 11 axially, the C shape snap ring 112 that shape is with it suitable is provided with in described hollow-out parts 111, the two ends of described C shape snap ring 112 are fixedly connected with the two ends of hollow-out parts 111, described C shape snap ring 112 relative socket part 11 inwall is in arranging to socket part 11 central axial direction convex shape.
It should be noted that herein, the processing of hollow-out parts 111 and C shape snap ring 112 is processed by a slice sheet material, first stamped out the raised line of convex at the middle part of sheet material by stamping die, then the upper and lower dual-side of cutting and separating raised line, again sheet material is bent in tubular, the two ends forming socket part 11 and C shape snap ring 112, C shape snap ring 112 are thus integrated with the mode that is fixedly connected with of socket part 11 and are connected.
