Abstract

The utility model discloses a socket which comprises a socket sleeve and a connection terminal. A contact piece in contact with a lead and an elastic piece in contact with a plug are arranged on the socket sleeve; the connection terminal is arranged on the lateral surface of the elastic piece; the top surface of the connection terminal is higher than the bottom surface of the elastic piece; the contact piece is inserted in the connection terminal; and the contact piece is connected with the elastic piece through a transversal extending piece. Compared with the prior art, the connection terminal is moved to the lateral surface of the plug sleeve from the front lower part of the socket sleeve to the lateral surface of the socket sleeve in the utility model and the position of the connectionterminal is elevated through structure improvement; and the whole thickness of the socket can be reduced on the premise of comforting to electrical safety, thereby enriching the variety of the socketand improving the product grade. Meanwhile, the corresponding package and the transportation cost also can be reduced.

Description

A kind of socket

Technical field

The utility model relates to a kind of combined socket and switch, particularly a kind of improvement technology that reduces socket thickness.

Background technology

Socket on the market generally includes a panel at present, panel has the sleeve that is connected with plug and lead line, the top of sleeve is the flexure strip that contacts with plug, the bottom is the contact chip that contacts with lead, under the sleeve riveted joint or lay binding post, contact chip is plugged in the binding post, side at binding post is provided with terminal screw, when power lead insert from the below of binding post put in place after, tighten terminal screw, lead be pressed on the contact chip get final product.Since binding post be arranged on sleeve under, therefore present socket its normally about 23mm, the thickness that comprises panel is about 35mm.And owing to need meet the GB requirement of electrical safety, therefore for the socket with earth polar sleeve, its gross thickness is difficult to reduce, and therefore makes socket seem very heavy, and the thickness of socket mounting box also needs to increase accordingly, thereby causes the waste on space and the cost.

The utility model content

The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of novel socket is provided, and is meeting under the prerequisite of electrical safety, reduces the thickness of socket.

The utility model is achieved by following technical proposals: a kind of socket, comprise sleeve and binding post, sleeve be provided with the contacted contact chip of lead and with the contacted flexure strip of plug, it is characterized in that: described binding post is arranged on the side of flexure strip, and the end face of binding post is higher than the bottom surface of flexure strip, contact chip is plugged in the binding post, is connected by horizontal Extendible flake between contact chip and the elastic foot.

The end face of described binding post is higher than the bottom surface 4～9mm of flexure strip.

The side of described Extendible flake is connected with the side of flexure strip, and the base of Extendible flake is connected with the top margin of contact chip.

Described Extendible flake is in-line or L shaped.

As further improvement of the utility model, the top of described contact chip is provided with the end plate that is 90 degree with contact chip.

One side of described end plate is connected with the top margin of Extendible flake.

The size of the size of described end plate and binding post upper surface is suitable.

Further improve as of the present utility model, a relative side that links to each other with Extendible flake on the described end plate is provided with the supporting bracket that is parallel to each other with contact chip, and the lower end overhead of described supporting bracket is in the upper surface of binding post.

With respect to prior art, the utility model moves to binding post under the sleeve side of sleeve, and improvement by structure, the position of binding post is raise, under the prerequisite that meets the GB2099.1 electrical safety, can reduce the integral thickness of socket, thereby enrich the socket product category, improve product specification.Simultaneously, corresponding packing and cost of transportation also can reduce.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model socket is described further:

As accompanying drawing 1 to 4, present embodiment is cited is one of them sleeve on the socket and the compound mode of binding post.Sleeve 1 comprises with the contacted contact chip 11 of lead and with the contacted flexure strip 12 of plug be connected the Extendible flake 13 of contact chip 11 and flexure strip.Extendible flake 13 begins horizontal expansion from the side of a slice flexure strip 12 wherein, extend suitable distance back (as 5～15mm, be as the criterion to meet the electrical safety requirement), L-shaped follow-up the reneing of bending 90 degree stretched proper width, and the base of this extension 13a and the top margin of contact chip 11 link into an integrated entity.Bending 90 degree after the top margin of this extension 13a extends upward about about 0～5mm laterally becomes end plate 14, is 90 degree with contact chip 11.A relative side that links to each other with Extendible flake 13 on end plate 14 is provided with and contacts 11 supporting brackets that are parallel to each other 15.When in the binding post 2 that contact chip 11 is inserted as shown in accompanying

drawing

1,2 time, because the size of end plate 14 is suitable with the size of binding post 2 upper surfaces, but so the equal overhead in the lower end of the extension 13a of Extendible flake 13 and supporting bracket 15 in the upper surface of binding post 2.When with panel-mounted together the time, the muscles and bones on the panel fastens upper surface at binding post 2 with end plate 14.Simultaneously, when lead inserts from binding post 2 lower ends, because stopping of end plate 14 arranged, make lead can excessively not insert, meet the requirement of GB2099.1, thereby guarantee security performance, in the time of in lead inserts binding post 2, terminal screw 3 screws in from the side of binding post 2, with lead fixed, and lead and contact chip 11 is kept in touch.

In the above-described embodiments, because the design of Extendible flake 13, make contact chip 11 be arranged on flexure strip 12 the side rather than under, the bottom surface that makes the end face of binding post 2 be higher than flexure strip 12 becomes possibility, therefore as long as control the size of Extendible flake 13 well, end face that just can binding post 2 is higher than the bottom surface 4～9mm of flexure strip 12.In the present embodiment, the main body of Extendible flake 13 is different in the size of thickness direction with the base of extension 13a, therefore makes the end face of binding post 2 be higher than the about 5.5mm in bottom surface of flexure strip 12.Thereby make that the thickness of whole socket can be by being reduced to about 28mm about present 35mm.

Sleeve 1 in the present embodiment is an integral type, after it can adopt the disposable stamping-out moulding of copper sheet, is bent into as the appearance in the accompanying drawing 2 again and gets final product.The sleeve in the present embodiment and the combining structure of binding post both can be used for the ground wire sleeve, also can be used for live wire sleeve or zero line sleeve.

The above only is preferred embodiment of the present utility model, not in order to restriction the utility model, as the shape of Extendible flake, the change of bearing of trend etc.All any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the utility model claim.
