Abstract

The utility model relates to an improved power-supply socket, comprising springs, a spring positioning strip, conductive strips, a contact strip frame, an insulator, a bolt, a panel and hinges. Each conductive strip is provided with the hinges and the springs, and the side of the conductive strip is provided with the springs. An independent elastic and independent hinge structure is used to make the utility model have the advantages of good contact of the power supply, high reliability, long service life and simple manufacturing process under the condition of frequent use. The utility model is suitable for single-phase or three-phase circular or flat plugs and various electrical equipment and the power-supply socket for high-grade electric equipment requiring good contact of the power supply.

Description

A kind of improved power socket
The utility model relates to a kind of supply socket of improvement.
At present, the market upper inlet, its kind of homemade supply socket is very various, modal structure is to rely on the elasticity of electric conductor self to finish grafting, simple in structure, be made up of a conducting strip and insulator, the problem of existence is that elasticity and conductivity can not be taken into account, after frequent the use, can not reply after the conductive copper sheet distortion, plug and socket contact area are minimum, and contact pressure and group slotting power size are uneven, and homogeneity of product is poor, after this infrastructure product uses a period of time, majority can come in contact bad phenomenon, also can produce electric arc sometimes and burn socket, or cause fire, use safety inadequately, and the life-span is short; Therefore, existing many people propose improvement project, as the multiple cushion socket, its structure is to add upper spring in the side of a long conducting strip, advantage is to insert a plurality of plugs on the conducting strip contact chip, but after inserting first plug, will add spring compression on the socket contact chip, because of being not autonomous system, after inserting other plug, also can produce the phenomenon of loose contact.Another structure is a cover lasso with resilience on inside and outside copper sheet, to increase elasticity, contact pressure is truly had benefit, but the elastic range of time power lasso is less, and comparatively difficult when plug is injected, feel is bad, and fatigue strength is lower.A structure is that conductive contact film is directly injection-moulded in the soft insulator again, utilizes the elasticity of soft body to increase the elasticity of contact chip, and advantage is that contact is better, but the elasticity of soft insulator is limited, and fatiguability, and the life-span is not long.
The purpose of this utility model provides a kind of simple in structure, and contact performance is good, the supply socket of long service life.
Structure of the present utility model comprises spring, spring spacer, conducting strip, contact horse, insulator, bolt, panel, hinge, each conducting strip is provided with hinge and spring, conducting strip is connected with the contact horse by hinge, and there is spring the side of conducting strip, and spring is located by the spring spacer.
The utility model adopts standalone elastic and discrete hinge syndeton, make under frequent operating position, can guarantee that still the power supply contact is good, the reliability height, long service life, the contact pressure of product and conductivity easily reach designing requirement, good product consistency, production technology is easy, and is single-phase, three-phase is circular, the flat plug is all applicable, is applicable to various electric equipments and to requiring the power supply base of the good senior power consumption equipment of power supply contact.
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the utility model embodiment 2 structural representations.
By accompanying drawing (1) as can be known, structure of the present utility model comprises spring (1), spring spacer (2), conducting strip (3), contact horse (4), insulator (5), bolt (6), panel (7), hinge (8), conducting strip (3) is connected with contact horse (4) by hinge (8), there is spring (8) side of conducting strip (3), spring (8) is located by spring spacer (2), conducting strip (3) and the hinge arrangement that is connected to that contacts horse (4), to improve mobility, and improved the fatigue strength of conducting strip (3), leave gap between two conducting strips (3) less than plug, after can making grafting like this, the parallel contact of trying one's best of plug angle and conducting sheet in socket, increase contact area, be easier to when plug is inserted; The size of spring (1), the power of elastic force are determined by socket power, go out and spring diameter corresponding grooves and bolt hole on the spring spacer (2), with fixing spring, conducting strip (3) the copper coin punch forming that conducts electricity very well and be difficult for oxidation, strike out the shape that conforms to plug with the plug contact portion, contact horse (4) is used and conducting strip (3) identical materials drawing, and goes out in the relevant position
Figure Y9520567900051
The hole of 3mm and rectangle are installed the slit, and in order to be connected and the fixed position with conducting strip, insulator (5) is the same with conventional socket with panel (7) part, available plastic injection-moulded forming.
The structure of Fig. 2 is substantially the same manner as Example 1, and different is that hinge (8) is a hinge typed structure.

Claims (3)

1. an improved power socket comprises spring, conducting strip, contact chip insulator, bolt, panel, it is characterized in that each conducting strip is provided with hinge and spring, and conducting strip touches by hinge and contact chip bridge joint, and there is spring the conducting strip side.
2. improved power socket according to claim 1 is characterized in that described hinge is a hinge structure.
3. improved power socket according to claim 1 is characterized in that described hinge is for inserting laminated structure.
