Abstract

The utility model relates to a symmetric pressing type power supply socket, which comprises an insulating bottom casing (1) and an insulating face casing (7). The middle of the insulating bottom casing (1) is provided with a fixed mount (8). The utility model is characterized in that in the insulating bottom casing (1), both sides of the fixed mount (8) are respectively provided with a conducting copper sheet (4); the copper sheets (4) and a wiring terminal (6) are fixed in the insulating bottom casing (1) by screws (9); a jack (10) is arranged on the face casing (7); a contact piece (5) which is curled into an r shape is arranged on each of the copper sheets (4) corresponding to the lower part of the jack (10); the outer side of each of the contact pieces (5) is provided with a groove (2) of a clamping spring in the insulating bottom casing (1); a spring (3) is clamped in the groove (2) of a clamping spring to press the outer side of the contact pieces (5); the face casing (7) is covered on the insulating bottom casing (1) and is fixed by screws (11).

Description

The supply socket of symmetry squash type

The utility model is a kind of symmetrical squash type supply socket.

At present, known supply socket is to adopt 4 conductive copper sheets to divide two set of contact plug bipods, and when this socket used, two easily dislocation up and down of copper sheet caused loose contact.In recent years the travelling contact type supply socket occurred, this socket adopts 2 conductive copper sheets, relies on outside ball spring to make it to contact with the plug bipod, has solved the problem of the mutual dislocation of upper-lower position when using, but the copper sheet in this socket is the single face conduction.

The purpose of this utility model provides a kind of symmetrical squash type supply socket, can solve the loosening mutually problem of upper-lower position, can solve the problem of single face conduction again.

The technical solution of the utility model is achieved like this: symmetrical squash type supply socket, comprise the insulation drain pan, the insulation face-piece, there is fixed mount centre at the insulation drain pan, it is characterized in that in the insulation drain pan, the both sides of fixed mount respectively are provided with a conductive copper sheet, conductive copper sheet and binding post are screwed in the insulation drain pan, on the insulation face-piece jack is arranged, there is the contact chip that is curled into the r shape corresponding position below jack, in insulator foot on the conductive copper sheet, the outside of contact chip is provided with the jump ring groove, spring snaps in the jump ring groove, and with the outside of extruding contact chip, the insulating surfaces clamshell is screwed after on the insulation drain pan.

The utility model compared with prior art, it is good to have contact performance, coefficient of safety is big, production cost is low.

Fig. 1 is an outside drawing of the present utility model;

Fig. 2 is a cut-away view of the present utility model;

Fig. 3 is the A-A cutaway view of Fig. 2;

Fig. 4 is the B-B cutaway view of Fig. 2.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

The symmetrical squash type supply socket of describing in the accompanying drawing, comprise insulation drain pan (1), insulation face-piece (7), there is fixed mount (8) centre at insulation drain pan (1), in insulation drain pan (1), the both sides of fixed mount (8) respectively are provided with a conductive copper sheet (4), conductive copper sheet (4) and binding post (6) are fixed in the insulation drain pan (1) with screw (9), on the insulation face-piece (7) jack (10) is arranged, corresponding position, below at jack (10), the contact chip (5) that is curled into the Y shape is arranged on the conductive copper sheet (4), in insulator foot (1), the outside of contact chip (5) is provided with jump ring groove (2), spring (3) snaps in the jump ring groove (2), and with the outside of extruding contact chip (5), insulation face-piece (7) covers on insulation drain pan (1), and upward the back is fixing with screw (11).As required, can make single-phase two cores, three cores and three-phase socket.

Claims
