Description

A kind of safety socket

The utility model relates to a kind of safety socket, refers to a kind ofly make the manufacturing more easy the DC safety socket structure that output improves especially.

The applicant once filed an application case number No. 88200474 " DC safety socket structure " patent application case, it includes down insulating base, axle, outer tube, the first terminal and second terminal constitute, this time insulating base end face forms a circle cancave cambered surface, following insulating base and tool one end plate and a cylinder, this axle is arranged at the column body of this time insulating base, the axle front end forms a head, mandrels backend is piercing in the end plate of this time insulating base, this outer tube sleeve is located at outside the cylinder of this time insulating base, this outer tube back-end is inserted into down in the end plate of insulating base, the upper end of the first terminal and second terminal is to be connected with axle and outer tube back-end respectively, and the first terminal and the second terminal lower end also protrude from down the insulating base bottom; Whereby, axle and outer tube are to adopt coaxial setting, and the round cancave cambered surface of following insulating base constitutes a holding groove, plug can be inserted at any angle, and contact conducting smoothly with socket, with the grafting of convenient joint, and the second terminal mid portion is that bending is horizontal-extending and is close to insulating base bottom, can be comparatively firm when being plugged on the circuit board.

Above-mentioned " DC safety socket structure ", though more existing socket is comparatively firm, but because members such as insulating base, axle, outer tube, the first terminal and second terminal under it, in assembling, comparatively bother, make the manufacturing of DC safety socket be difficult for, inconvenience is beneficial to the raising of output, and this kind design is still imperfect.

It is more easy that the purpose of this utility model provides a kind of manufacturing, is convenient to the DC safety socket that output improves.

For achieving the above object, the utility model is taked following design:

A kind of safety socket is characterized in that, is provided with:

One axle, its front end and rear end are formed with a Plug Division and a caulking part respectively;

One outer tube, it is sheathed on the outside, Plug Division of axle, and outer tube also maintains certain spacing with axle;

One the first terminal, it is shaped in outer tube back-end, and the first terminal is to have first pin;

One insulator, its ejection formation are in outside pipe, and axle and outer tube back-end, and insulator inside is to form a spliced eye, and first pin of the first terminal is to stretch out in the insulator bottom, and the caulking part of mandrels backend is to stretch out in the insulator rear end;

One second terminal is to have a riveted holes on it, and in order to the caulking part of riveted and fixed in mandrels backend, this second terminal is to have second pin, and this second pin is to stretch out in the insulator bottom.

The caulking part front end of its central shaft is provided with a loop mapping flange.Second terminal can borrow the locating flange of axle that the function of block location is provided.

The first terminal is to be an inverted Y-shaped lamellar body, and this first terminal is to have two first pins.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a three-dimensional appearance schematic diagram of the present utility model.

Fig. 2 is a perspective exploded view of the present utility model.

Fig. 3 is a side-looking generalized section of the present utility model.

Fig. 4 is a schematic rear view of the present utility model.

Fig. 5 is the still last schematic perspective view in conjunction with second terminal of the utility model.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5; A kind of improved safety socket structure, this socket 10 is to include an axle 11, an outer tube 12, a first terminal 13, an insulator 14 and one second terminal 15 to constitute, its central shaft 11, outer tube 12, the first terminal 13 and second terminal 15 are to make with electric conducting materials such as copper, this axle 11 is to be a waney cylinder, its front end and rear end are formed with a Plug Division 16 and a caulking part 17 respectively, this caulking part 17 is to be hollow shape, and caulking part 17 front ends are provided with a loop mapping flange 21.

Outer tube 12 is to be a hollow round tube body, it is 16 outsides, Plug Division that are sheathed on axle 11, outer tube 12 also maintains certain spacing with axle 11, separate state so as to forming two utmost points, outer tube 12 rear ends have extended to form a first terminal 13 downwards, make this first terminal 13 one-body molded outer tube 12 rear ends that are connected in, this first terminal 13 is an inverted Y-shaped lamellar body, and this first terminal 13 is to have two first pins 18.

Insulator 14 is made with insulating material such as plastic cement, its ejection formation is in outer tube 12 outsides, and axle 11 and outer tube 12 rear ends, make axle 11 and outer tube 12 be able to strong fix, insulator 14 inside are the spliced eyes 22 that form a circle, can be in order to plug with the plug that docks, two first pins 18 of the first terminal 13 are to stretch out in insulator 14 bottoms, the caulking part 17 of axle 11 rear ends is to stretch out in insulator 14 rear ends.
