Description

Supply socket

Technical field

The utility model relates to a kind of supply socket, particularly relates to five metals sleeve in the socket and plastic cement structure are carried out improved a kind of technology.

Background technology

Socket is an indispensable electrical accessorie during people live, socket mainly is made up of plastic shell and the pin insertion spring that is arranged in the plastic shell, the pin that is provided with triplets and two one group on the surface of plastic shell inserts mouthful, pin inserts spring and is positioned at pin insertion mouth, insert in the mouth at ternary pin, wherein two inclinations mutually, another inserts on mouthful center line that is arranged on two insertion mouths that tilt mutually and is positioned at the big at interval side of mutual inclination.The sleeve major part that pin inserts on the spring is bent into tight mouthful of " U " shape use by copper sheet, has elasticity and conductivity.Pin in the insertion mouth that people generally will tilt mutually inserts spring and is called the L utmost point or the N utmost point, and the pin of the insertion mouth in the middle of will being positioned at inserts spring and is called the E utmost point.People common to disjunctor two or three pole sockets in, the L utmost point or N extremely mainly are made up of two braces of extremely inserting between the extremely slotting sleeve of the extremely slotting sleeve and two, three of sleeve, three, the L utmost point or N three in extremely inserts extremely that sleeves are general to adopt following structure: a kind of structure is three extremely to insert sleeves and formed by an end ecto-entad bending of brace, increased the length of material, in high volume production process, three of this structure is extremely inserted sleeve must waste a large amount of metal materials; Another structure is that three extremely slotting sleeves are formed by meal gold die stamping by sheet metal, and then fixedlys connected with brace by riveted joint or other connected mode, and three of this structure is extremely inserted comparatively complexity of sleeve operations, installs cumbersome.There is complex procedures extremely equally in E in disjunctor two or three pole sockets, the shortcoming of trouble is installed.

Summary of the invention

The utility model provides a kind of external form fineness, production and installation simple for solving above-mentioned technical barrier, the novel power supply socket that reduce production costs, electric conductivity has dustproof and defencive function well, simultaneously.The utility model is for realizing technique scheme, the utility model supply socket, and socket is provided with panel, and frame covers in face plate edge, and socket also is provided with back cover, and there is the elastic copper sheet of three and two s' pin insertion the inside.In the pin of triplets and two group inserts mouthful, in inserting mouthful, the triplets pin establishes three-way copper sheet; Described ternary pin inserts in the mouth, wherein two are tilted mutually, another inserts on mouthful center line that is arranged on two insertion mouths that tilt mutually and is positioned at the big at interval side of mutual inclination, it is characterized in that: the sleeve that pin inserts on mouthful interior insertion spring is formed by the bending of E shape sheet metal, become two contact chips of sleeve after the two outer side edges bendings of E shape sheet metal, medial side is bent into the ground wire copper sheet of the wiring of sleeve.Have on the three-way copper sheet limit in described pin inserts mouthful a bending downwards " " the shape contact chip is linked square binding post to L.Insert mouthful at two one group pin, both sides have two line copper sheets respectively, and there is a projection centre, individual hole are arranged after on the limit, and just the button bit with the projection of plastic back shell fastens, and is fixed, and has " L " shape contact chip of bending to be connected to square binding post on the limit.Two contact chips of the sleeve on the described insertion spring become the U-shaped shape, and the intermediate connection sheet becomes L shaped shape.The screw of binding post employing 5MM compresses the contact chip of two line copper sheets and three-way copper sheet, and wiring can be inserted lead from top, the back cover back side, and the side gets final product screw tightening.When rear shell cover was on panel, the pillar on the panel was fixed elastic copper sheet, then key screw back cover and panel was fixed.So design, since insert a contact chip of the sleeve on the spring in the utility model and be on the brace an end from inside to outside bending form, thereby can make full use of the metal material on the brace, can not resemble present sleeve and come bending to form sleeve the increase of the end on brace length, thereby reduce the manufacturing cost of product.In representative in the past disjunctor two or three pole sockets, the E utmost point three is extremely inserted sleeve and is generally formed by the bending of T shape sheet metal, when punching press T shape sheet metal, the metal material of T shape sheet metal dual-side breach is taken as waste material and gets rid of, thereby brings the wide variety of materials waste.The extremely slotting sleeve of the E utmost point three can form by an E shape sheet metal bending in disjunctor two or three pole sockets of the present utility model, E shape sheet metal only needs a spot of metal material of punching press just can obtain, therefore, the utility model E utmost point three is extremely inserted sleeve can reduce manufacturing cost significantly, makes structure become more simply, assemble convenient simultaneously.The plastic cement on the utility model both sides is isolated conductive copper sheet fully.Be provided with plate washer in pin inserts mouthful, enter socket and protect the electric shock that inserts in the hole of extraneous conducting metal to prevent dust.

The utility model electric outlet structure is simple, and number of components is few, saves raw material, and is easy for installation, low cost of manufacture, and use is not fragile; Inserting when socket is idle and at panel mouthful has plate washer, can prevent that dust from entering socket, also can prevent the electric shock that inserts in the hole of extraneous metalwork.
