Abstract

The utility model relates to a plug socket. The plug socket is an inserting member for the electricity supply of a power supply. At least two groups of contact sheets are fixed on a base by fastening members, two edges of the contact parts of the contact sheets are elastically clamped by spring bent sheets, the contact sheets and binding screws are connected by electricity conductive sheets, and then, an upper cover is fixed on the base to form the plug socket. The utility model has the advantages of simple structure, low cost, long service life, small contact resistance, and very stable and reliable use. The plug socket is especially suitable for the plug socket of the power supply of a household electrical appliance.

Description

Plug socket

The utility model relates to a kind of connector assembly, belongs to the connector that the power supply power supply is used.

Past, the connector assembly that the power supply power supply is used, the contact chip simple shape that its inner connector block is adorned, elastic force is poor, and be easy to deformed damaged, and cause and use instability, it is unreliable to contact, switch-on and-off, the contact position constantly produces electric arc, and not only power supply quality is poor, but also household electrical appliance such as badly damaged refrigerator of powering, television set, washing machine, video tape recorder and recorder, up to now, power supply is powered also the connector assembly of low contact resistance in the employed connector assembly as yet.

It is poor that the purpose of this utility model is to overcome the connector block elastic force that has connector assembly, easy deformation, cause and use instability, it is unreliable to contact, switch-on and-off, the contact position constantly produces electric arc, the shortcoming of badly damaged household electrical appliance, thus provide a kind of have the contact reliable and stable, contact resistance is little, can improve the connector assembly of power supply quality effectively, be suitable for providing the usefulness of household electrical appliance power supply.

The purpose of this utility model realizes by following approach:

The utility model includes loam cake, base, contact chip, the spring bending, conducting strip, parts such as terminal screw constitute, it is fixed on the base with securing member by at least two winding contacts, clamp with the contact site two limit elasticity of spring bending contact chip, with conducting strip contact chip is connected with terminal screw again, to be provided with identical then with contact chip group number, the loam cake of the jack that the position matches is screwed on base and constitutes, be provided with identical with contact chip group number at said base correct position, the shrinkage pool that size matches, be convenient to install the usefulness of contact chip, also being provided with through hole in the shrinkage pool bottom, is the screw hole of fixed contact piece; Contact chip is made with elastic sheet metal, and shape is " U " shape only, all inwardly curves " X " shape at its symmetrical top, is provided with installing hole in its bottom, is provided with arc groove in its contact site, is convenient to flat plug and round plug is general; The spring bending is also made with elastic sheet metal, the shape Lower Half is only semicircle, and the first half is symmetrical " X " shape only, slick and sly each other the connection, with the inside of spring bending clamping contact chip, be fixed in the shrinkage pool of base with the through hole of securing member screw by the contact chip bottom.

Fig. 1 is a front view of the present utility model, and Fig. 2 is the A-A partial sectional view of Fig. 1.

The utility model describes in detail below with reference to accompanying drawing embodiment:

The utility model embodiment includes loam cake (1), base (2), contact chip (4), spring bending (5), conducting strip (6), terminal screw parts such as (7) constitutes, it is fixed on the base (2) with screw (8) by two groups of contact chips (4) with spring bending (5) clamping contact site (13), use conducting strip (6) that contact chip (4) is connected with terminal screw (7) again, the loam cake (1) that will be provided with two jacks (14) that match in contact chip (4) position then is fixed on base (2) with screw (3) and goes up and constitute, go up correct position at said base (2) and be provided with two shrinkage pools (9) that match with contact chip (4), be convenient to install the usefulness of contact chip (4), also being provided with through hole (12) in shrinkage pool (9) bottom, is the screw hole of fixed contact piece (4); Contact chip (4) is made with the tin-phosphor bronze sheet, and shape is " U " shape only, all inwardly curves " X " shape at its symmetrical top, is provided with installing hole (11) in its bottom, is provided with arc groove (10) in its contact site; Spring bending (5) is made with spring steel plate, the shape Lower Half is only semicircle, the first half is symmetrical " X " shape only, slick and sly each other the connection, clamp contact chip (4) contact site (13) with spring bending (5), contact chip (4) is fixed in the shrinkage pool (9) of base (2) with the through hole (12) of screw (8) by contact chip (4) bottom.

The utility model has following advantage compared to existing technology:

1. contact chip of the present utility model adopts the compound bending shape, and elasticity is increased, and compression distance increases;

2. have the spring bending that its elasticity is clamped in the contact chip of the present utility model, its pressure is increased, contact resistance obviously reduces during use;

3. the utility model contact chip is fixed in the shrinkage pool of base, and is highly stable reliable during use.
