Description

Structure improved four utmost point plugs

The utility model refers to a kind of 2.5mm specification that more is applicable to especially about a kind of four utmost point plugs, makes simply, and structure improved four utmost point plugs that reduce production costs.

Four traditional utmost point plugs are made of axle, two sections pipes, three sections pipes and four sections pipes, and between axle, two sections pipes, three sections pipes and four sections pipes, respectively be provided with an insulator, make axle, two sections pipes, three sections pipes and four sections pipes form four utmost points and separate shape, so constitute one or four utmost point plugs.

But, above-mentioned four utmost point plugs are owing to respectively be provided with an insulator between axle, two sections pipes, three sections pipes and four sections pipes, therefore be provided with three layers of separately insulator of moulding altogether, the setting of these insulators makes the manufacturing of this plug comparatively bother, and produces and assemble to go up to increase many inconvenience on foot, cause cost higher, especially in four utmost point plugs of diameter 2.5mm than small dimension, the difficulty of its production process is bigger, therefore the design of the rare 2.5mm specification of general four utmost point plugs.

Main purpose of the present utility model is to provide a kind of structure improved four utmost point plugs, and insulator is wherein made in one-body molded mode, makes to produce and assemble simply easily, and then significantly reduces production costs.

The structure improved level Four plug that the utility model provides, include axle, two sections pipes, three sections pipes, four sections pipes and insulator, its central shaft front end has a bigger head, two sections pipe boxes are located at the axle outside, and maintain spacing with axle, and the head of axle front end and mandrels backend are exposed to the front end and the rear end of two sections pipes; It is outside that three sections pipe boxes are located at two sections pipes, and with two sections guarantee and hold spacing that and two sections pipe front ends and rear end are exposed to three sections pipe front ends and rear end; It is outside that four sections pipe boxes are located at three sections pipes, and with three sections guarantee and hold spacing that and three sections pipe front ends and rear end are exposed to four sections pipe front ends and rear end; Insulator is arranged at respectively between axle and the two sections pipes, between two sections Guan Yusan section pipes and between three sections Guan Yusi section pipes, and be provided with the connecting portion that the three can be connected in each section insulator rear end.

The utility model mainly is that the insulator of four utmost point plug constructions is made in one-body molded mode, make the manufacturing of insulator become comparatively easily simple, thereby make whole plug comparatively simple on manufacturing, produce and the production cost that conveniently makes of assembling significantly reduces, be particularly useful for the manufacturing of diameter 2.5mm than four utmost point plugs of small dimension.

Wherein, described two sections pipes, three sections pipes and four sections pipes are not isometrical hollow round tube body;

Wherein, the connecting portion of described insulator is towards extending axially.

Describe feature of the present utility model and technology contents in detail below in conjunction with accompanying drawing and preferred embodiment.

The explanation of accompanying drawing drawing:

Fig. 1 is a three-dimensional combination figure of the present utility model.

Fig. 2 is a three-dimensional exploded view of the present utility model.

Fig. 3 is a cutaway view of the present utility model.

Fig. 4 is an end view of the present utility model.

See also accompanying drawing 1,2,3,4, the utility model provides a kind of structure improved level Four plug, especially be applicable to the level Four plug of 2.5mm specification, include an axle 10, one or two sections pipes 11, one or three sections pipes 12, one or four sections pipe 13 and one insulators 14, its central shaft 10, two

sections pipes

11,12 and four sections pipes 13 of three sections pipes are to make with electric conducting materials such as brass, axle 10 front ends have a bigger head 15, two sections pipes 11 are not isometrical hollow round tube body greater than axle 10, and these two sections pipes 11 are sheathed on axle 10 outsides, and maintain certain spacing with axle 10, the length of these two sections pipes 11 makes the head 15 of axle 10 front ends and rear end be exposed to two sections pipe 11 front ends and rear end less than axle 10.Three sections pipes 12 are not isometrical hollow circular tube alms bowl greater than two sections pipes 11, these three sections pipes 12 are sheathed on two sections pipe 11 outsides, and 11 maintain certain spacing with two sections pipes, and the length of these three sections pipes 12 is less than two sections pipes 11, make two sections pipe 11 front ends and rear end be exposed to three sections pipe 12 front ends and rear end, four sections pipes 13 are not isometrical hollow round tube body greater than three sections pipes 12, and these four sections pipes 13 are sheathed on three sections pipe 12 outsides, and 12 maintain certain spacing with three sections pipes, the length of these four sections pipes 13 makes three sections pipe 12 front ends and rear end all be exposed to the front end and the rear end of four sections pipes 13 less than three sections pipes 12.Insulator 14 is made with insulating material such as plastic cement, its with the injection molding method filling be arranged between axle 10 and the two sections pipe 11, between 11 and three sections pipes 12 of two sections pipes and three sections pipes manage between 13 for 12 and four sections, and insulator 14 rear ends between

axle
