Description

The self-locking safety power supply socket

Affiliated technical field

The utility model relates to a kind of supply socket with plug automatic blocking.

Background technology

At present, the basic structure of known supply socket is that conductive reed is fixed in the socket, inserts the Elastic Contact turn-on power of pawl by reed and plug.Because the elasticity of reed is limited, frequent plug plug, the difference of various plug size very easily make the Die for Reeds of Connector Jack fatigue deformation, and plug is loosening, causes virtual connection, produces electric arc.The harm of electric arc is conspicuous, and it can burn various electrical equipment and equipment in the circuit.Newer technological improvement generally also just improves the reed shape and increases reed thickness to improve chucking power.Like this, reed is often really up to the mark, and bigger frictional resistance makes plug plug tension, needs both hands firmly to separate when especially pulling away, and is promptly inconvenient, also dangerous.

Summary of the invention

The purpose of this utility model is to realize with pressing the mechanism of self-locking, and therefore the clamping of forcing receptacle connector that plug is inserted pawl has auto-lock function, and clamping is firm, and is loosening to avoid plug.Simultaneously, this mechanism discharges this clamping with key mode again, is convenient to plug and easily pulls away.It is the most convenient, with low cost that the chucking power of this press type self-locking mechanism is generally finished with mechanical type.It also can be realized with the various ways of known magnetic-type, fluid pressure type, vapour-pressure type and drive of motor.It is applicable to the various supply sockets that need improvement of safety.

Usefulness of the present utility model is thoroughly to have avoided the reed distortion that causes because of a variety of causes between plug and the socket, the infringement that plug is loosening, the virtual connection starting the arc brings for various electrical equipment.Pressing plug during operation is taken advantage of a situation firmly, this power just finished socket to the clamping of plug with fixing.After the clamping of plug is released, when pulling away, plug do not have the phenomenon of tension, and simple to operate, safe ready.Its loam cake has single dust cap, stops dust to the obstruction that the seat core slides respectively, prevents that the control piece operation is malfunctioning.

Embodiment

With the core (5) among Fig. 1, seat core guide pillar (16), seat core spring (15), loam cake (6) and support (9) assembling, a core also can be endwisely slipped than loam cake upper edge is protruding; With tentacle A (13), tentacle B (14), bearing pin A (10), tentacle spring (12) and support (9) assembling, make tentacle A (13), tentacle B (14) have required elastic force opening and closing angle, and swing in the bipyramid face of the present core of tentacle A, tentacle B; Contact (11), weld tabs (17) are placed in tentacle B (14) upper end, and weld tabs (17) connects known power lead; Chute (3) is fixed in seat core (5) both sides of loam cake (6).

In Fig. 2, with claw A (7), claw B (8), claw spring (20), bearing pin B (18) and loam cake (6) assembling, claw A (7), claw B (8) cooperate with ratchet with seat core (5), utilize elasticity reverse (making progress) locking seat core (5), claw A (7), claw B (8) should be able to keep sliding in chute (3).

In Fig. 3, snapper axle (19) is installed among loam cake (6), claw A (7), claw B (8), snapper spring (21), each hole of lower cover (22), and cone separates claw A (7), claw B (8) when pressing down snapper axle (19).

In Fig. 6, knob camshaft (23) is installed among loam cake (6), claw A (7), claw B (8), each hole of lower cover (22), and cam separates claw A (7), claw B (8) during knob camshaft (23) rotation.

In Fig. 7, dust cap (24), hinge axis (25) are assemblied in the hinge hole of loam cake (6), make dust cap (24) do 0 °～270 ° upsets.

Principle of the present utility model is: when oblique core plug (1) inserts seat core (5), two slotting pawls (2) of power supply have laid respectively in the middle of tentacle A (13), the tentacle B (14), continue press operation down, the inner biconial face of seat core (5) forces two groups of tentacle A (13), tentacle B (14) to close up simultaneously, two groups contact (11) compresses a pair of slotting pawl (2) simultaneously, make the power supply conducting simultaneously of two slotting pawls (2) respectively by weld tabs (17), claw A (7), claw B (8) reverse locking seat core this moment (5) must not return by pine, realizes the self-locking of oblique core plug (1).Fig. 1 right side is the self-locking state of straight core plug (4).Single power supply is inserted pawl also can the same manner self-locking.This shows, the swing in the biconial face of core (5) because tentacle A (13), tentacle B (14) can be present, it is stronger to inserting pawl (2) adaptivity, can adapt to oblique core plug (1) and straight core plug (4), and the bigger plug of slotting pawl (2) error.

When pulling out oblique core plug (1) or straight core plug (4), press snapper axle (19), its cone separates claw A (7), claw B (8), a core (5) is released and upsprings, tentacle A (13), tentacle B (14) resilience, contact (11) unclamps with slotting pawl (2), cuts off the electricity supply automatically.Unclamp snapper axle (19), snapper spring (21) is upspring snapper axle (19), and claw (7) A, claw B (8) have so far finished basic operation because of claw spring (20) elastic force recovers initial clamping to seat core (5).

Fig. 4 is parallel method of clamping, and the bearing pin A (10) on the support is for being arranged in parallel, and the jack and the shape of seat core (5) are corresponding with it.This kind socket can satisfy the needs of oblique core plug (1) and straight core plug (4) simultaneously, and it is widely used in all kinds of ordinary appliances.

Fig. 5 is that angle is 50 °～70 ° a method of clamping, and bearing pin A (10) hole on the support is that angle is arranged, and the jack and the shape of seat core (5) are corresponding with it.The closed of its power supply three-phase is good, is suitable for accurate, the important electrical equipment and the power supply occasion of equipment.

The utility model can Fig. 4 parallel method of clamping make combination below 20, angle that also can Fig. 5 is that 50 °～70 ° method of clamping is made the combination below 20, can also their mixing method of clamping makes the combination below 40.

Fig. 6 is the another kind of method that discharges seat core (5) locking, by the rotation of knob camshaft (23), with isolated in form claw A (7), the claw B (8) of cam.

Among Fig. 7, dust cap (24) is dustproof state at 0 ° of angle, at 90 °～270 ° angles with the interior opening that is.Dust cap (24) is evenly distributed by the quantity of above-mentioned actual needs, single open and close.
