The spin safe supply socket of band plug retaining mechanism
Technical field
The utility model relates to a kind of spin safe supply socket with the plug retaining mechanism, especially for the safety power source plug socket of low-voltage electrical apparatus.
Background technology
The supply socket of prior art, its design principle all are to adopt elastic copper sheet to clamp attaching plug to realize current lead-through.In a single day elastic copper sheet follows the string or is out of shape and just cause loose contact in this structure, and the conductive copper sheet of this socket is exposed outside by jack, uses and life is easy to generate electric shock accidents.The spin safe supply socket patent No. is the unsafe problems that ZL 00 2 293390 has solved the supply socket jack and the binding post coordination of prior art substantially, but this socket in use plug still can come off, the drawback that the conventional socket binding post exposes in jack appears, to people's the bigger hidden danger of personal safety formation.
Summary of the invention
The purpose of this utility model is to address the above problem, and a kind of mechanism's spin safe supply socket with plug locking is provided.
The technical solution of the utility model is: the spin safe supply socket of band plug retaining mechanism, comprise that case top lid, following of housing, jack, rotating shaft and binding post constitute, form the right-angled trapezium space between inboard inclination of its binding post and the jack rotating shaft, be inlaid with the right-angled trapezium electric conductor of band plug retaining mechanism in the right-angled trapezium space, lift the convex double-vane of right-angled trapezium electric conductor when there is a pair of the rotation jack rotating shaft lower end.
The spin safe supply socket of described band plug retaining mechanism, its plug retaining mechanism is in right-angled trapezium conduction body cavity the catotropic support spring in two ends to be housed, one end of support spring is fixed, the vertical plane bottom opening place of the naked close jack rotation shaft side in the right-angled trapezium electric conductor of the other end, a positioning seal head is arranged at right-angled trapezium electric conductor bottom.
The spin safe supply socket of described band plug retaining mechanism, the angle of the inboard inclination of its binding post is to become 15-30 ° of angle with Y-axis.
The spin safe supply socket of described band plug retaining mechanism, the inclined-plane of its right-angled trapezium electric conductor also become 15-30 ° of angle with Y-axis.
The spin safe supply socket of described band plug retaining mechanism, its support spring is naked to go out to hold the vertical plane bottom opening 0.1-0.5mm of naked close jack rotation shaft side for the right-angled trapezium electric conductor.
The spin safe supply socket of described band plug retaining mechanism, its binding post inboard is interior arcuation, and the inclined-plane of right-angled trapezium electric conductor is the outer arcuation that matches.
The spin safe supply socket of described band plug retaining mechanism, the right-angle plane of its right-angled trapezium electric conductor and the rib of two sides are the cambered surface that radius is 0.2-0.8mm.
The spin safe supply socket of described band plug retaining mechanism, the end socket of its right-angled trapezium electric conductor bottom is by plastic production.
When advantage of the present utility model is non-working condition, the inlet wire binding post of jack position and socket certain angle that staggers, binding post is hidden in the inside of socket, and binding post is exposed.Retaining mechanism can reliably be locked plug in the special use, guarantees not take place mistake and comes off.Because the binding post inboard is interior arcuation, the inclined-plane of right-angled trapezium electric conductor is the outer arcuation that matches, can compensate because the loose contact that the error of plug copper sheet is brought, the plug copper sheet is closely contacted with binding post by the right-angled trapezium electric conductor, improved the heating phenomenon that conventional socket produces because of contact resistance, can allow big electric current to pass through, enlarge load capacity.Plug and contacting of socket do not rely on self elasticity of copper material, and greatly improve useful life.

Embodiment accompanying drawings of the present utility model:
The spin safe supply socket of band plug retaining mechanism shown in Figure 1 is made up of case top lid 1, following 2, jack rotating shaft 3, plug retaining mechanism; Jack rotating shaft 3 is inserted in down on seat 2 newels by loam cake 1, and its hollow space is inserted a rotating shaft back-moving spring 5.Have a pair of on jack rotating shaft 3 two sides for plug copper sheet 7 insertion grooves 12 formation jacks 11.There is a pair of convex double-vane 4 at the place corresponding to groove 12 bottoms.Respectively there is a square hole following seat both sides.The angle of the inboard inclination of binding post is to become 15-30 ° of angular region with Y-axis, and the inclined-plane of its right-angled trapezium electric conductor also becomes 15-30 ° of angle to match with Y-axis.Be embedded with hollow right-angled trapezium electric conductor 8 at the trapezoid space between jack rotating shaft 3 and the binding post above the base, its inclined-plane is near binding post 6, and the binding post inboard is interior arcuation, and the inclined-plane of right-angled trapezium electric conductor is the outer arcuation that matches.The right-angle plane of right-angled trapezium electric conductor and the rib of two sides are the cambered surface that radius is 0.2-0.8mm, help the plug rotation.Hollow right-angled trapezium electric conductor 8 inside are embedded with termination support spring 9 down, one end of support spring 9 is naked in the vertical plane bottom opening place of right-angled trapezium electric conductor 8, support spring is naked to go out to hold the vertical plane bottom opening 0.1-0.5mm of naked close jack rotation shaft side for the right-angled trapezium electric conductor to be advisable, the rotation of i.e. not overslaugh plug copper sheet 7 has to guarantee locking effect.Right-angled trapezium electric conductor 8 bottoms are sealed by plastic end enclosure 10.
The operation principle of embodiment of the present utility model is achieved in that under non-working condition, and as Fig. 1: jack rotating shaft 3 jack 11 and binding post 6 when initial position certain angle that staggers, at this moment, binding post 6 is exposed in jack.In use, as Fig. 2: when plug inserts, plug is rotated by jack rotating shaft 3, and jack rotating shaft 3 bottom convex double-vanes 4 lift right-angled trapezium electric conductor 8, plug copper sheet 7 closely contacts power turn-on by right-angled trapezium electric conductor 8 with binding post 6.Support spring 9 exposed terminations forward are butted on plug copper sheet 7 outsides in the right-angled trapezium electric conductor 8.When the stressed pumpback of plug mistake, reverse movement plug copper sheet 7 is blocked in the support spring 9 exposed terminations of plug retaining mechanism, and right-angled trapezium electric conductor 8 stressed together motions, because it is big little under its shape, as a timber wedge wedge between plug copper sheet 7 and binding post 6, more pull and push head then wedge must heal tightly, stop the plug extraction.Have only when plug and jack rotating shaft 3 cycle initial positions, when having avoided right-angled trapezium electric conductor 8, plug could be extracted out.This moment, socket was in non-working condition again, had stopped binding post by the exposed situation of jack.
Fig. 3 is a plug locking mechanism structure schematic diagram: right-angled trapezium electric conductor 8, support spring 9, positioning seal head 10.
Fig. 1-Fig. 3 has provided the embodiment of two plate socket, and the structure of three grades of formula sockets is removed the position difference of jack and plug retaining mechanism, and its concrete structure and two spring hole scokets are identical.
