Abstract

The utility model discloses a power socket provided with steel wire clips, and the power socket comprises a socket body, the socket body is provided with plug holes, and the plug holes are provided with steel wire clips used to clamp plugs inserting the socket. The steel wire clip comprises an arc spring, a U-shape spring, and a contact sheet; the arc spring is formed by bending a steel wire, and the U-shape spring is a U-shape steel wire arranged in middle of a torsion spring; a top of the contact sheet is provided with a trunnion, the trunnion inserts a cavity in middle of the torsion spring, and a bottom of the contact sheet is arranged between the arc spring and the u-shape spring. The power socket provided with the steel wire clips enable the plugs to be difficult to come off, improves bearing power of the socket, and has advantages of simple structure, easy making and processing property, and the like.

Description

Be provided with the supply socket of steel wire dop

Technical field

The utility model relates to a kind of supply socket that is provided with the steel wire dop.

Background technology

Socket is one of object commonly used in the daily life.Existing socket is that jack is set in pedestal; be provided for clamping the chuck of the sheet metal of plug in the jack; but the chuck in the existing receptacle sockets adopts elastic sheet metal to make usually; clamping force is less; usually can become flexible after plug inserts and come off; contact area between plug metal film and the chuck is less in addition; so that the resistance at contact point place is larger; the phenomenon that the socket heating occurs easily; so that socket burns when using high-power electric appliance easily, use socket to bring very large inconvenience to people.

The utility model content

The utility model is the weak point that exists in the above-mentioned prior art for avoiding, and a kind of supply socket that is provided with the steel wire dop is provided, so that plug difficult drop-off and improve the load power of socket.

The utility model be the technical solution problem by the following technical solutions.

Be provided with the supply socket of steel wire dop, comprise pedestal, described pedestal is provided with jack, is provided with the steel wire dop that is inserted into the plug of socket for clamping in the described jack, its design feature is that described steel wire dop comprises bow-shaped shrapnel, U font shell fragment and contact chip; Described bow-shaped shrapnel is to be formed by the steel wire bending, and described U font shell fragment is to be arranged on the middle U font steel wire of torsion spring; The upper end of described contact chip is provided with gudgeon, and described gudgeon is inserted in the middle cavity of torsion spring, and described contact chip bottom is located between described bow-shaped shrapnel and the U font shell fragment.

The design feature that the utility model is provided with the supply socket of steel wire dop also is:

Described contact chip is copper sheet; Described bow-shaped shrapnel is made of two toxoplasms that are twisted into by steel wire; The both sides of described U font shell fragment are torsion spring, and the torsion spring of the two ends of described U font shell fragment and U font shell fragment both sides is set to one.

Compared with the prior art, the utility model beneficial effect is embodied in:

Adopt bow-shaped shrapnel and torsion spring, by the elasticity of shell fragment and torsion spring is set, can so that the clamping force of dop is moderate, so that plug can not become flexible and come off after inserting, improve the fail safe that electric equipment uses.Contact chip made of copper is set between two shell fragments, so that the contact area between plug and the dop enlarges, and then so that the resistance of contact part is less, reduced the caloric value at the some place of pegging graft when using high-power electric appliance, thereby improved the load power of socket, improved the security performance when using high-power electric appliance.Adopt the structures such as bow-shaped shrapnel, torsion spring on the structure, simple in structure, manufacture easily low cost of manufacture.

The supply socket that is provided with the steel wire dop of the present utility model, have so that the plug difficult drop-off and improve socket load power, simple in structure, make the advantage such as handling ease.

Description of drawings

Label in accompanying drawing 1～accompanying drawing 4: 1 pedestal, 2 jacks, 3 plugs, 4 steel wire dops, 5 bow-shaped shrapnels, 6 U font shell fragments, 7 contact chips, 8 torsion springs, 9 gudgeons.

Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.

Embodiment

Referring to Fig. 1～Fig. 4, be provided with the supply socket of steel wire dop, comprise pedestal, described pedestal 1 is provided with jack 2, is provided with the steel wire dop 4 that is inserted into the plug 3 of socket for clamping in the described jack 2.Described steel wire dop 4 comprises bow-shaped shrapnel 5, U font shell fragment 6 and contact chip 7; Described bow-shaped shrapnel 5 is to be formed by the steel wire bending, and described U font shell fragment 6 is for being arranged on the U font steel wire of torsion spring 8 centres; The upper end of described contact chip 7 is provided with gudgeon 9, and described gudgeon 9 is inserted in the cavity of torsion spring 8 centres, and described contact chip 7 bottoms are located between described bow-shaped shrapnel 5 and the U font shell fragment 6.When plug inserted socket of the present utility model, the inserted sheet of plug was stuck between bow-shaped shrapnel and the contact chip, at described contact chip one end by U font shell fragment tensioner.Because bow-shaped shrapnel and the distance between the contact chip of socket are less than the inserted sheet thickness of plug, thereby inserted sheet inserts rear to bow-shaped shrapnel, U font shell fragment generation extruding, bow-shaped shrapnel, U font shell fragment are because the elasticity of self, inserted sheet to plug produces a reaction force, thereby plug is stuck in the jack tightly.The one side of inserted sheet contacts with bow-shaped shrapnel, another side contacts with contact chip and by the tensioning of U font shell fragment, contacting between inserted sheet and the contact chip is the face contact, some contact or line contact than the dop that has socket now, contact area is larger, thereby the resistance of contact position is just smaller, can be not overheated and burn socket at contact position when using high-power electric appliance, thereby improved the load power of socket, improved the security reliability that socket uses.

Described contact chip 7 is copper sheet; Described bow-shaped shrapnel 5 is made of two toxoplasms that are twisted into by steel wire; The both sides of described U font shell fragment 6 are torsion spring 8, and the torsion spring 8 of the two ends of described U font shell fragment 6 and U font shell fragment 6 both sides is set to one.

Socket of the present utility model, 30 centimetres steel wire add two small pieces copper sheets, just can be made into the dop of a Double-hole socket, and cost is very low.Conventional socket then needs a bulk of copper sheet, through shearing, is stamped to form again, and is more complicated than cushion socket of the present utility model on the manufacturing process, also more expensive on the cost.
