Abstract
A socket insertion sleeve structure is provided. The socket insertion sleeve structure comprises a metal insertion sleeve arranged inside a socket and a metal connecting sheet. The socket insertion sleeve structure is characterized in that a torque arm is arranged between the metal insertion sleeve and the metal connecting sheet; the torque arm, the metal insertion sleeve and the metal connecting sheet are of an integrated structure which is formed through stamping a metal copper material; and the torque arm is an arc-shaped metal sheet. According to the socket insertion sleeve structure of the utility model which is of structural simplicity, the torque arm is additionally adopted, such that the thickness of the copper material can be greatly reduced, and therefore, production cost can be reduced; when a plug is inserted into the metal insertion sleeve, a plug pin will make the insertion opening of the metal insertion sleeve outwards expended and deformed, at this moment, the torque arm generates an opposite twisting force, as a result, the insertion opening will be contracted inwards and tightly clamps the plug pin. The elasticity and insertion/pulling forces of the socket insertion sleeve structure of the utility model are stronger than those of a traditional insertion sleeve, and the service life of the socket insertion sleeve structure is longer than that of the traditional insertion sleeve.
Description
Technical field
The utility model relates to a kind of electrical fitting, specifically a kind of socket plug-in cover structure.
Background technology
Existing plug bush structure is very simple, by conductive metal sheet, is bent and is formed, and during use, plug base pin directly inserts in sleeve.Because copper material has good conductivity, so the material of sleeve is generally selected copper material.But, due to the elasticity of copper material own a little less than, after pin repeatedly plugs, copper sheet will be out of shape, and makes contact and become flexible between pin and sleeve, easily produces loose contact.In order to address the above problem, have to adopt the copper material that thickness is larger, but current copper material price is very expensive, make whole socket cost high.Therefore, be necessary to be further improved.
Utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, cost is low, the socket plug-in cover structure of long service life, to overcome weak point of the prior art.
A kind of socket plug-in cover structure by this object design, comprises the metal insertion cover and the metal connecting sheet that are installed in socket, and its architectural feature is to be connected with toggle between metal insertion cover and metal connecting sheet.
Described toggle and metal insertion cover, metal connecting sheet are the integrative-structure that metal copper material is stamped to form, and toggle is arc metal plate.
Described metal insertion cover is comprised of two copper sheets arranged side by side that have each other gap, and the corresponding toggle of two copper sheets surrounds up-narrow and down-wide interstitial structure.The quantity of described metal insertion cover is mate with plug one or more, and a metal insertion cover correspondence is provided with two toggles.
The utility model is simple in structure, by increasing toggle, can significantly reduce copper material thickness, thereby reduce production costs; When plug inserts metal insertion cover, latch can make the socket of metal insertion cover expand outwardly distortion, and at this moment toggle just can produce relative torsion, makes socket inwardly shrink latch is tightly clamped, and its elasticity and contact engaging and separating force, life-span are all good than traditional sleeve.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Referring to Fig. 1, a kind of socket plug-in cover structure, comprises the metal insertion cover 1 and the metal connecting sheet 2 that are installed in socket, between metal insertion cover 1 and metal connecting sheet 2, is connected with toggle 3.The integrative-structure that toggle 3 and metal insertion cover 1, metal connecting sheet 2 are stamped to form for metal copper material, toggle 3 is arc metal plate.Metal insertion cover 1 is comprised of two copper sheets arranged side by side that have each other gap, and metal insertion cover 1 correspondence is provided with the corresponding toggle 3 of two toggles, 3, two copper sheets and surrounds up-narrow and down-wide interstitial structure.
When plug inserts metal insertion cover 1, latch can make the socket of metal insertion cover 1 expand outwardly distortion; At this moment toggle 3 just can produce relative torsion, makes socket inwardly shrink latch is tightly clamped.
The utility model is not only limited to above-mentioned example, and in essential scope of the present utility model, the variation of making, remodeling, increase or replacement, also belong to protection range of the present utility model.
