Abstract

The utility model discloses a socket structure which includes a socket body. The socket body is provided inside with two symmetrically arranged copper sheets which are used to contact the pins of an outer plug. The lower portion of the copper sheet is bended to form a pedestal, while the upper portion is a two-section structure composed of a middle section and an upper end section, wherein a surface of the middle section corresponding to the outside of the pedestal is a flat surface, the outside surface of the middle section projects from the outside surface of the upper end section; an inner side of the upper end portion corresponding to the pedestal projects from the inner side surface of the middle section, the middle of the upper end portion is a semicircular arc; and the inner side surface of the middle section also has a semicircular arc projection. The design uses one copper sheet to satisfy the above requirements by making use of the different spacings of the American standard pin and the European standard pin. Different from the conventional design, in the design, the contact direction of the two copper sheets is against with the direction of the conventional copper sheets, and since the magnitudes of interference of the American standard pin and the European standard pin are similar in design, the American standard pin and the European standard pin can be integrated to share one copper sheet.

Description

A kind of structure of socket

Technical field

The utility model relates to a kind of supply socket.

Background technology

On the current market a kind of universal contact receptacle is arranged, input has the variety classes pin, but the universal contact receptacle that output can cooperate Europe and U.S.'s pin to use.Because of there is the safety pin of two kinds of sizes in Europe, a kind of is to pass through 2.5A electric current, pin diameter 4.0mm, centre distance 17.5mm; Another kind is to pass through 16A electric current, pin diameter 4.8mm, centre distance 19.0mm.

Product on the current market generally has two kinds.First kind is by the contact of three copper sheets, and this kind copper sheet is to utilize the wherein U.S. rule of a slice copper sheet contact pin, other two copper sheets contact Europe rule pin, and this design can be satisfied requirements such as slotting power and pull out force, temperature, but many because of contacting copper sheet, and cost is expensive relatively.Second kind is that two sides copper sheet contact is arranged, and the relative three copper sheets contact of cost is cheap, same, wherein a slice copper sheet contact U.S. advises pin, and another sheet copper sheet contact Europe rule pin is because of centre distance, pin diameter differ, it is qualified to make Europe rule insertion diameter 4.8mm, but diameter 4.0mm can be loose partially.

The utility model content

At the problems referred to above, the utility model aims to provide and a kind ofly saves material, is connected firmly, and can be applicable to the socket of many moneys fork pin types simultaneously.

For realizing this technical purpose, scheme of the present utility model is: a kind of structure of socket, comprise jack body, be useful on two symmetrically arranged copper sheets of contact male connector pin in the described jack body, the bottom bending of this copper sheet is base, its top is divided into interlude and upper end section two-stage structure, and wherein: the face of the corresponding chassis outer side of interlude is the plane, and this lateral surface is raised in the lateral surface of upper end section; The inner bulge of the corresponding base of upper end section in interlude medial surface, the centre position of this upper end section is a semi arch; The medial surface of interlude also projection has semicircle arcuation projection.

The design utilizes U.S. rule pin, Europe to advise the different spacing of pin, utilizes a slice copper sheet, satisfies above every requirement.Different with existing design, the design is opposite with the direction of the two copper sheets contacts in current market, and U.S. rule design in, the Europe rule pin magnitude of interference are similar, can be incorporated into beautifully advise, Europe advises the shared a slice copper sheet of pin.The first, can satisfy contact engaging and separating force, temperature requirement that three copper sheets contact on the function; The second, the material aspect can contact more material saving than three or two copper sheets.

Description of drawings

Fig. 1 is the copper sheet structural representation in the socket of the present utility model.

Fig. 2 is the schematic diagram that copper sheet of the present utility model combines with U.S. rule pin.

Fig. 3 is the schematic diagram that copper sheet of the present utility model combines with Europe rule pin.

Embodiment

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

As shown in Figure 1, the structure of a kind of socket of the present utility model, comprise jack body, be useful on two symmetrically arranged copper sheets 1 of contact male connector pin in the described jack body, the bottom bending of this copper sheet 1 is base 2, its top is divided into interlude 3 and upper end section 4 two-stage structures, and wherein: the face of interlude 3 corresponding chassis outer side is the plane, and this lateral surface is raised in the lateral surface of upper end section; The inner bulge of upper end section 4 corresponding bases in interlude 3 medial surface, the centre position of this upper end section 4 is a semi arch; The medial surface of interlude 3 also projection has semicircle arcuation projection.

Be U.S. rule UL specification pin in the accompanying drawing 2, can touch the copper pin outside.For Europe rule pin, can utilize two kinds of different centre distances, diameters without pin in the accompanying drawing 3, the most approaching in copper pin inboard, the copper sheet deflection is similar, and copper sheet can cooperate two Europe rule copper pin simultaneously.This design, same copper sheet, the inboard can cooperate U.S. rule pin, and the outside can cooperate two kinds of different Europe rule pins.In addition, the design utilizes the butt-joint technology, and copper sheet is connected, and firmly reaches and saves material.

The above; it only is preferred embodiment of the present utility model; not in order to restriction the utility model, every foundation technical spirit of the present utility model to any trickle modification that above embodiment did, be equal to and replace and improve, all should be included within the protection range of technical solutions of the utility model.

Claims

1. the structure of a socket, comprise jack body, it is characterized in that: two symmetrically arranged copper sheets that are useful on contact male connector pin in the described jack body, the bottom bending of this copper sheet is base, its top is divided into interlude and upper end section two-stage structure, wherein: the face of the corresponding chassis outer side of interlude is the plane, and this lateral surface is raised in the lateral surface of upper end section; The inner bulge of the corresponding base of upper end section in interlude medial surface, the centre position of this upper end section is a semi arch; The medial surface of interlude also projection has semicircle arcuation projection.
