Abstract

The utility model relates to a socket connector which is characterized in that the utility model is composed of a plug, a socket, a wire-embrace type plug protective tail and a rubber sheath, wherein the wire-embrace type plug protective tail forms a cylinder shape and is hollow, and the diameter of the top of the wire-embrace type plug protective tail is smaller; the outer circumference of the wire-embrace type plug protective tail is provided with annular bulges, the rear parts of the bulges are connected with annular grooves, and the bottoms of the bulges are provided with internal threads; the rubber sheath forms a cylinder shape and is hollow, and the top of the rubber sheath is necked down; two lines of parallel annular bulges are arranged in the bottom end of the rubber sheath, and a groove is formed between the bulges; the annular bulges at the top end of the wire-embrace type plug protective tail are clamped in the groove for positioning, and the annular bulges at the inner edge of the bottom end of the rubber sheath are clamped in the annular grooves of the wire-embrace type plug protective tail for fixing; the rear part of the socket is provided with a positioning lug boss. The utility model can be accurately fixed at a given position, without looseness and rotation. The utility model prevents the outer skin and the core of a conducting wire from impairment.

Description

Plug connector

The utility model relates to a kind of plug connector, refers to a kind of plug connector of embracing line formula plug retaining tail and rubber sheath that has especially.

At present, there are some problems in the plug connector that the connection circuit is used, influence is normal to be used, for example: socket can not be fixed on plug connector on the selected a certain angle exactly, after socket is given a shock, easily get loose or rotate, influence contact point reliability, destroy solder joint, in addition, easily cause wire sheath breakage, wire stylet frangibility etc.

The purpose of this utility model is that a kind of plug connector will be provided, and it not only pegs graft stable, reliable, and damage wires not.

The purpose of this utility model is achieved in that plug connector is made up of plug and socket, also is provided with the plug retaining tail of embracing line formula band rubber sheath; The socket rear portion is provided with positioning boss; Embrace line formula plug retaining tail and be tubular, hollow, its top diameter is slightly smaller than the middle and lower part, and its outer peripheral edges have circular projection, rear raised portion connecting ring groove; Internal thread is arranged at the bottom; Rubber sheath is convex shape, tubular, hollow, the top necking down, and the bottom diameter is a bit larger tham embraces line formula plug retaining tail top end diameter; The parallel annular projection of twice is arranged in the rubber sheath bottom, form groove therebetween, groove matches with the circular projection of embracing line formula plug retaining tail top, and the circular projection of rubber sheath bottom inner edge just can be fastened in the ring groove of embracing line formula plug retaining tail; There is positioning boss at the socket rear portion.

Because adopt such scheme, the boss at the utility model socket rear portion can be fixed on plug connector on the selected a certain angle exactly; And the plug retaining tail of embracing line formula band rubber sheath can be realized contacting with lead is soft, and wire sheath can breakage like this, and wire stylet is frangibility not also; Dial to insert quick and conveniently, connect reliable, safety.

Below by accompanying drawing and embodiment the utility model is further described.

Fig. 1 is that the utility model embodiment assembles and partly cuts open figure.

Fig. 2 embraces line formula plug retaining tail 3 half to cut open figure among the utility model embodiment.

Fig. 3 is that rubber sheath 4 half cuts open figure among the utility model embodiment.

Fig. 4 is positioning boss 5 locations drawing of socket among the utility model embodiment.

Among the figure: 1 plug, 2 sockets, 3 armfuls of line formula plug retaining tails, 4 rubber sheaths, 5 positioning boss, 6 circular projectioies, 7 ring grooves, 8 internal threads, the parallel annular projection of 9 twice, 10 grooves, 11 casings.

Referring to Fig. 1; The utility model embodiment mainly comprises a plug 1, a socket 2, one armful of line formula plug retaining tail 3 and rubber sheath 4.

As shown in Figure 2; Embrace line formula plug retaining tail 3 and be tubular, hollow is during its top diameter is slightly smaller than, the diameter of bottom; The top outer peripheral edges have circular protruding 6, and effect is can tightly be stuck in the groove 10 of rubber sheath 4; Be connected with ring groove 7 at circular protruding 6 rear portions; Embracing line formula plug retaining tail bottom has internal thread, so that be spirally connected socket 2.

As shown in Figure 3; Embrace line formula plug retaining tail 3 and be furnished with rubber sheath 4.Rubber sheath 4 is convex shape, tubular, hollow; The diameter of embracing line formula plug retaining tail 3 tops is a bit larger tham in top necking down, its bottom diameter; The parallel annular projection 9 of twice is arranged in rubber sheath 4 bottoms, form groove 10 therebetween, groove 10 and circular protruding 6 matching of embracing line formula plug retaining tail 3 tops, and circular protruding 6 just can being clamped in the ring groove 7 of embracing line formula plug retaining tail of rubber sheath 4 bottom inner edges.Embrace line formula plug retaining tail 3 with rubber sheath 4 with lead with embrace line formula plug retaining tail 3 soft being linked together, make not frangibility of lead.The rubber sheath that can be furnished with different inner diameters is so that adapt to the lead of different-diameter.

Shown in Fig. 4,5; Be provided with positioning boss 5 at the rear portion of socket 2, be used for location, spline, can exactly socket 2 be fixed on a certain selected angle.By screw thread and the boss 5 of nut socket 2 is fixed on the casing 11 of installation position with socket 2 rear portions.
