Abstract

The utility model relates to a structure of a socket for power source, which is composed of a panel 1, a back base 11, an electrode piece 3, etc., wherein the electrode piece 3 is arranged in an independent cavity 2 which is formed by the panel and the base. The electrode piece of the utility model is a clamping structure which is based on a torsion spring; as a result, compared with the traditional electrode piece, the electrode piece 3 of the utility model has the characteristic of not generating permanent deformation, so the socket for power source has the advantages of large clamping and contacting area, stable clamping force, and long service life.

Description

A kind of supply socket

The utility model relates to supply socket.

Though supply socket kind, specification, style commonly used are a lot, all exist the not enough problem of contact pressure.Use phosphorus bronze sheet to do electrode in order to address this problem some producer with increase pressure, when the contact point heating produces intensification, phosphorus bronze sheet can be aggravated the increase of oxidation contact resistance and be caused temperature rise higher, so causes vicious circle, follows the string until phosphorus bronze sheet " annealing ".More there is part producer to do electrode very thickly,, brought chucking power excessive, easily produce problems such as the pin that fractures during use though the problems referred to above make moderate progress.On Chinese patent, also there is the travelling contact type socket to occur, as disclosing a kind of socket among the patent No. ZL94244301.2 " a kind of electrical socket ", its main feature is the independent cavity of this socket corresponding to corresponding formation in each the Kong Weiyu rear base on the panel, be provided with spring base in this cavity, spring and copper sheet contact chip, utilize the elastic force of spring to press the copper sheet contact chip, as if compare with above-mentioned technology, this socket can effectively improve the problems such as reliability of the pressure of plug and copper sheet contact.But after in fact plug inserts this socket, just single face is subjected to the spring pressure movable contact, spring also just can not produce pressure to another side because the plug distance can not be packed under the restriction of national standard, be effective contact-making surface instead for socket commonly used half, uses and causes loose contact generation temperature rise to burn out easilier.

The purpose of this utility model is to propose a kind of simple in structure, uses good hand touch, contacts good socket.

In order to achieve the above object, the utility model is achieved in that a kind of supply socket, comprise an independent cavity corresponding to corresponding formation at the end behind each Kong Weiyu on the panel, in this cavity electrode is arranged, electrode is with there being two lower ends of negative and positive all to be washed into " door " shape groove, and side-looking is middle perforate semicircle lug, the upper end is the copper material of the recessed the tip of the tongue shape of little introversion and makes, at the relative built-in torque spring in space that forms of negative and positive sheet two lower end semicircle lugs, one copper latch passes the lug centre bore, torque spring is combined into the three at the electrode of condensing tube tongs formula structure.

The utility model adopts condensing tube tongs formula electrode structure to substitute traditional electrode, because two-sided phase clamping structure, it is big that folder touches area, and chucking power is stable, and it is light to have feel, and contact resistance is little, superiority such as dependable performance.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Accompanying drawing 1 is the utility model socket schematic diagram

Accompanying drawing 2 is the utility model electrode structure schematic diagrames

The utility model is two spring hole scokets, the panel 1 and the base 11 that have two holes in accompanying drawing 1 form two independent cavitys 2, and phosphor-copper electrode 3 is housed in each cavity, and electrode 3 is by cathode sheets 4, anode strip 6, the condensing tube tongs (accompanying drawing 2) that torque spring 5 latches 7 combine.Yin, yang two pole piece lower ends all are pressed into protruding half garden ear shape, and the recessed tongue shape of little introversion is made in the upper end, also stretch out one " L " shape support 8 in anode strip 6 lower ends and are connected into terminal as circuit, and screw 10 is fixed on electrode 3 on the cavity 2.

Electrode fixing device of the present utility model can also produce with the groove of base.

When attaching plug inserted electrode 3 of the present utility model, negative and positive two pole pieces were subjected to squeeze and open, and two-sided maintenance constant pressure makes plug and the stable contact-making surface of pole piece two sides generation under the effect of torque spring 5 simultaneously.When plug was transferred to, cloudy two pole pieces were drawn close recovery under torque spring 5 effect, guaranteed that like this pole piece can not produce permanent deformation, and having reached folder, to touch area big, and chucking power is stable, long-lived effect.

Claims

1, a kind of supply socket comprises an independent cavity (2) corresponding to corresponding formation in each the Kong Weiyu rear base (11) on the panel (1), electrode (3) is arranged in this cavity, it is characterized in that: the electrode in the structure is with two lower ends of negative and positive all middle one-tenth " door " shape groove, and perforate half garden lug in the middle of the side-looking, the upper end is the silver-plated metal material (4) of the recessed the tip of the tongue shape of little introversion, (5) make, in negative and positive sheet (4), (5) two lower ends half garden lug forms in the space relatively, put a torque spring (5), one steel latch (7) passes each lug centre bore (9), and torque spring (5) is combined into the three at the electrode (3) of condensing tube tongs formula structure.

2, supply socket according to claim 1 is characterized in that, this condensing tube tongs electrode material is that silver-plated copper sheet is stamped to form.

3, according to the described supply socket of claim 1, it is characterized in that: this condensing tube tongs electrode material is that phosphorus bronze sheet is stamped to form.
