Abstract

The utility model provides a traveling contact-type power supply socket, which is composed of a base, a cover casing, a U-shaped contact strip, a spring and a copper ball. The copper ball and the spring are clamped between the corresponding two long sides of the U-shaped contact strip of each jack. When a plug is inserted into the traveling contact type power supply socket, one side of the plug strip has a direct static contact with the contact strip; in addition, through the long side of the outer side of the U-shaped contact strip, the spring and the copper ball, the copper ball has a traveling contact with the other side of the plug strip under the pressure of the spring; simultaneously, the copper ball is pressed into a circular hole on the plug strip by the spring, which enlarges the contact surface and has locking function. The utility model has the advantages of no contact resistor between the plug and the socket, small consumption, long service life, no influence to each other and tightening wire connection of supply leads. The traveling contact-type power supply socket gets rid of bad contact phenomenon effectively.

Description

Travelling contact type power supply socket

The utility model relates to the travelling contact type supply socket in a kind of electrical equipment plug connector.

For the supply socket of a large amount of uses, people require it to contact well with plug.For this reason, various types of sockets are arranged in the prior art, " multiple cushion socket " (85203892), " long-life supply socket " (87202413) as the Chinese patent bulletin, though they all adopt spring structure, changed the mode of only utilizing the elastic force of contact chip own, but in the multiple socket, just increased the floating pressure type structure of public tension spring, plug has not been had locking action, still often caused the loose contact of plug and socket.

The purpose of this utility model is to overcome above-mentioned weak point and provides a kind of quiet contact to combine with movable the contact, and plug is had locking action, the good travelling contact type supply socket of contact.

Technical solution of the present utility model is such, and it is made up of base, case, contact chip, spring and copper ball.Contact chip is Qian shape copper sheet, is fixed in the vertical slot of base, snaps in copper ball and spring by the circular hole on the base between two inboards of corresponding each jack, and case is screwed after covering on the base.

Accompanying drawing 1 is the utility model shape assumption diagram.

Accompanying drawing 2 is the A-A cutaway view.

Accompanying drawing 3 is understructure figure.

Now in conjunction with the accompanying drawings the utility model is made detailed description:

The travelling contact type supply socket is made up of base 1, case 2, contact chip 3, spring 4 and copper ball 5.Base 1 is a cuboid, two long limit faces have dovetail groove 8, upper surface vertically has and is drilled with two circular holes 10 on two grooves 9 and the longitudinal centre line and has attacked screw thread, on a horizontal end face, be drilled with two circular holes 11, fix a nut 7 in the circular hole respectively, so that fixed contact piece 3 and power supply are introduced wiring, be drilled with several corresponding to the rectangle jack 13 on the case 2 to circular hole 12 from two long limit face longitudinal centre lines, two groove 9 directions of surface longitudinal that make progress; Case 2 is the rectangle cover, it is several to slot 13 that upper surface is with base 1 horizontal circular hole 12 that the center has accordingly, and be drilled with circular hole 14 respectively and have breach 15 downwards with respect to thread circle hole 10 on the base 1 upper surface longitudinal centre line and circular hole 11 places on the horizontal end face, so that case 2 and base 1 bolt and power line are introduced; Contact chip 3 is two Qian shape copper sheets.With copper ball 5 and spring 4 be taken up in order of priority pack each circular hole 12 into from 1 liang of long limit of base face after, again two Qian shape contact chips 3 are inserted in respectively in 1 liang of long limit of base dovetail groove 8 and the close upper surface cannelure 9, copper ball 5 and spring 4 are snapped between 3 liang of long limits of Qian shape contact chip, the circular hole that passes Qian shape contact chip 3 horizontal end faces with screw 6 is connected with nut 7 with two circular holes 11 of base 1 one horizontal end faces then, and from then on two screw places introduce power line, at last case 2 are covered on the base 1 then to be screwed on base 1 at upper surface.As required, also can make single-phase three cores and three-phase socket.

The utility model is owing to adopt above design, copper ball 5 and spring 4 are snapped between 3 liang of long limits of Qian shape contact chip, behind plug insertion socket, the one side of plug blades direct contact with socket contact chip 3 (the quiet contact), pass through the outer long side of Qian shape contact chip 3 in addition, spring 4, copper ball 5, rely on the pressure of spring 4 to make copper ball 5 closely contact (moving contact) with the another side of plug blades, simultaneously copper ball 5 is pressed in the circular hole on the plug blades by spring 4, makes contact-making surface broadening, has played locking action again, non-contact resistance between plug and the socket, reduced contact loss, long service life, but plug is more than 50,000 times, make socket, each connection is independent of each other; Wiring nut 7 is fixed in the base 1 one horizontal end face circular holes 11, makes wiring more fastening, overcome effectively present all kinds of socket remain the loose contact phenomenon.

Claims

1, a kind of travelling contact type supply socket, it comprises case (2), case (2) is the rectangle cover, upper surface with base (1) laterally circular hole (12) to be that the center has accordingly several to slot (13), and locate to be drilled with respectively circular hole (14) and have breach (15) downwards with respect to thread circle hole (10) on base (1) the upper surface longitudinal centre line and the circular hole (11) on the horizontal end face, its base (1) that is characterised in that of the present utility model is a cuboid, two long limit faces have dovetail groove (8), upper surface vertically has and is drilled with two circular holes (10) on two grooves (9) and the longitudinal centre line and has attacked screw thread, on a horizontal end face, be drilled with two circular holes (11), fix a nut (7) in the circular hole (11) respectively, be drilled with several corresponding to the slot (13) on the case (2) from two long limit face longitudinal centre lines, two grooves of surface longitudinal (9) direction that makes progress to circular hole (12), contact chip (3) is two Qian shape copper sheets, be inserted in respectively in the dovetail groove (8) and close upper surface cannelure (9) of the long limit of base (1) two face, snap in a copper ball (5) and a spring (4) respectively in each horizontal circular hole (12) of the base (1) between Qian shape contact chip (3) two long limits.
