The utility model comprises a head, a front and a back middle pipes, an outer tube, an insulator, a first terminal, a second terminal and a spindle, wherein, the insulator comprises a first insulator which is sheathed on the spindle, a second insulator which is sheathed on the outside of the first insulator, a third insulator and a body; the body is arranged in the outer pipe; the front ends of the first and the second terminals are respectively clamped between the first insulator and the front middle pipe and between the second insulator and the back middle pipe; the third insulator is arranged on the back end of the first and the second terminals and the spindle.

Description

Assembly type four utmost point plugs

The utility model belongs to the telecommunication transmission circuit connector component, particularly a kind of assembly type four utmost point plugs.

Four utmost point plugs system of commonly using as shown in Figure 1, is made up of pipe 11a and outer tube 12a in head 10a, the front and back two.Head 10a rear end extends axle 13a; Pipe 11a and outer tube 12a are that spacer sleeve is located at outside the axle 13a of head 10a rear end in two, and in head 10a, two, be filled with

insulator

14a, 15a and 16a with injection molding method between pipe 11a and outer tube 12a, make among the head 10a, two pipe 11a and outer tube 12a form four utmost points and separate shape, to constitute four utmost point plugs.

This four utmost point plugs of commonly using, it is very tiny wherein to manage parts such as 11a, outer tube 12a and axle 13a among the head 10a, two, crooked skew when

insulator

14a, 15a and 16a ejection formation easily, cause each utmost point to be in contact with one another, form short circuit, the product fraction defective is improved, production cost increases.

The purpose of this utility model provides that a kind of each utmost point insulate, stay in grade, cost is low, product percent of pass is high assembly type four utmost point plugs.

The utility model comprises head, preceding middle pipe, rear middle tube, outer tube, insulator, the first terminal, second terminal and axle; Forward and backward middle pipe and outer tube spacer sleeve place on the axle and are positioned at the head rear end; Insulator comprises first insulator, second insulator, the 3rd insulator and body; Body places in the outer tube, and is exposed to the outer tube front and back ends; First insulator is sheathed on the axle and is positioned at the head rear end, and preceding middle pipe, second insulator and rear middle tube are sheathed on outside first insulator in regular turn; The first terminal front end is folded between first insulator and preceding middle pipe, and contacts with preceding middle pipe; The second terminal front end is folded between second insulator and rear middle tube, and contacts with rear middle tube; The 3rd insulator places first, second terminal and mandrels backend, with first, second terminal of interval and mandrels backend.

Wherein:

First insulation system is a waney hollow tube.

Axle is inserted on the head with its front end; Be provided with pad between its rear end and the 3rd insulator.

Because the utility model comprises head, forward and backward middle pipe, outer tube, insulator, first and second terminal and axle; Insulator comprises first insulator that is sheathed on the axle, is sheathed on first insulator outer second insulator, the 3rd insulator and body; Body places in the outer tube; First and second terminal front end is folded in respectively between first insulator and preceding middle pipe and second insulator and rear middle tube; The 3rd insulator places first and second terminal and mandrels backend.The utility model system makes with group mode, improved and commonly used four utmost point plugs because of the too small and as easy as rolling off a log generation skew in the ejection formation process of part, cause each utmost point to be in contact with one another, cause the drawback of short circuit, each utmost point is insulated, do not have situation about being in contact with one another stay in grade takes place, can reduce production costs and the product fraction defective, thereby reach the purpose of this utility model.

Fig. 3, be the utility model decomposition texture schematic isometric.

Fig. 4, be the utility model structural representation front view.

Fig. 5, be the utility model structural representation cutaway view.

Below in conjunction with accompanying drawing the utility model is further elaborated.

As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model comprises head 1, first insulator 2, preceding middle pipe 3, rear middle tube 3 ', second insulator 4, outer tube 5, the 3rd insulator 6, the first terminal 7, second terminal 8, pad 9, body 10 and axle 11.

Head 1, preceding middle pipe 3, rear middle tube 3 ', outer tube 5, the first terminal 7, second terminal 8, pad 9 and axle 11 etc. are to be made by electric conducting material.First insulator 2, second insulator 4, the 3rd insulator 6 and body 10 are to be made by insulating material.

During the assembly process,, and make body 10 be exposed to outer tube 5 front and back ends in outer tube 5 inner ejection formation bodies 10.First insulator 2 is a waney hollow tube, and it is arranged in head 1 rear end.Before, rear middle tube 3,3 ' inwall then cooperates the front end of the first terminal 7 and second terminal 8 respectively, and in first insulator, 2 outer walls by preceding then be arranged with in regular turn before in the pipe 3, second insulator 4 and the rear middle tube 3 ', make the first terminal 7 front ends be folded in first insulator 2 and reach 3 of preceding middle pipes, the first terminal 7 front ends can contact with preceding middle pipe 3, second terminal, 8 front ends are folded between second insulator 4 and rear middle tube 3 ', second terminal, 8 front ends can contact with rear middle tube 3 ', then body 10 and the outer tube 5 that is combined into one is sheathed on first insulator, 2 outer walls, again with axle 11 rear end tie spacers 9 and the 3rd insulator 6, pad 9 is to be located at the 3rd insulator 6 rear sides, with axle 11 through first insulator, 2 inside, then axle 11 front ends are fixed in head 1 rear end, to constitute four utmost point plugs.Head 1, forward and backward in pipe 3,3 ' and outer tube 5 can separate four utmost points by first insulator 2, second insulator 4 and body 10 and separate shape, the end 13 of the end 12 of axle 11 rear ends, the first terminal 7 rear ends, the end 14 of second terminal, 8 rear ends and the end 15 of outer tube 5 rear ends, can distinguish welding lead, so that the signal transmission.

The utility model system makes with group mode, and the situation that each utmost point is not had be in contact with one another takes place, and stay in grade can reduce production costs and the product fraction defective, and can be made into the elongated plug.

In sum, the utility model has improved commonly uses four utmost point plugs because of the too small and as easy as rolling off a log generation skew in the ejection formation process of part, causes each utmost point to be in contact with one another, and causes the drawback of short circuit, reduce the fraction defective and the production cost of product, and can be made into strip four utmost point plugs.
