Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor Every other embodiment obtained, fall within the protection scope of the utility model.In the following description, in order to clearly demonstrate originally The structure and working method of utility model will be described on the basis of attached drawing by many Directional words, but should be incited somebody to action The Word Understandings such as "front", "rear", "left", "right", "upper", "lower" are not construed as word of limitation for convenience of term.

Embodiment 1

The self-tightening type safety electrode structure of socket shown in Fig. 1-2, first be installed on when including using on socket base 10 Electrode intermediate plate 1, and the second electrode intermediate plate 2 with 1 corresponding matching of first electrode intermediate plate；The first electrode intermediate plate 1 includes group The fixed arm 3 being connected when dress with socket base 10, one end and 3 upper end of fixed arm are connected, the other end is bent downward and to socket aperture The support arm 4 and lower end and support arm 4 that center extends towards socket aperture center one end the connected, other end stretch out upwards, be in The clamp arm 5 of arc shape；The upper end of the clamp arm 5 has the bending part 6 bent outward；The inner concave of the clamp arm 5 Towards socket aperture center；The planform of the second electrode intermediate plate 2 is identical as the planform of first electrode intermediate plate 1；Assembling When second electrode intermediate plate 2 be symmetrically arranged on socket base 10 with first electrode intermediate plate 1, and second electrode intermediate plate 2 and first electric Upper and lower ends corresponding position on pole intermediate plate 1 is close, and second electrode intermediate plate 2 is corresponding with the upper and lower ends on first electrode intermediate plate 1 There are gaps at place, not electric with second when electrode plug is initially inserted into when the gap width of upper end is greater than the thickness of electrode plug Pole intermediate plate and the contact of first electrode intermediate plate, can avoid surprisingly touching electrode plug in fragment position at the beginning of the insertion and cause electric shock, Improve the safety used.

The fixed arm 3, support arm 4 and clamp arm 5 are integrated as a preferred technical solution, can be used bending or The common electrode material such as phosphor copper can be used in person's punch forming, material.

In the present embodiment, the fixed arm 3 of first electrode intermediate plate and second electrode intermediate plate is in L-shaped shape, and when use passes through Card slot is arranged on socket base to be clamped, or is attached using screw.

Its use state is as shown in Fig. 2, when the electrode plug 20 of plug is inserted into from the hole of socket, under electrode plug End enters from the upper end bending part of first electrode intermediate plate and second electrode intermediate plate, at this time first electrode intermediate plate and second electrode intermediate plate The part A that closes on top do not contacted with the electrode plug of insertion；With the continuous insertion of electrode plug, when the end of electrode plug Part B(first electrode intermediate plate and second electrode intermediate plate are closed in the lower part of portion's arrival first electrode intermediate plate and second electrode intermediate plate Gap herein is less than the thickness of electrode plug) when, electrode plug end pushes first electrode intermediate plate and second electrode intermediate plate Part B is closed in lower part, and the lower end of the clamp arm of first electrode intermediate plate and second electrode intermediate plate is mobile to down either side respectively, this When electrode plug clamped by the part B that closes on of the lower part of first electrode intermediate plate and second electrode intermediate plate, due to first electrode intermediate plate And the part B that closes on of the lower part of second electrode intermediate plate is moved to two lower sections, its opposite force of support arm extrusion at this time increases (be identical to be pressurized elastic slice), the reaction force of support arm are simultaneously squeezed also clamp arm to press to electrode plug close to contact electrode Inserted sheet finally acts on reaction force on electrode plug by closing on part A and closing on part B, realizes and presss from both sides to first electrode The top of piece and second electrode intermediate plate closes on the engagement of part A and reinforces clamping force.Due to using the above structure, when clamping It is reliable and stable, and the end of only electrode plug reach the lower part of first electrode intermediate plate and second electrode intermediate plate close on part B When just need slightly to exert oneself, plug electrode plug extract during, when electrode plug end disengage neighbouring part B When, the clamping force of first electrode intermediate plate and second electrode intermediate plate weakens, and can easily extract convenient for electrode plug, therefore using very It is convenient.

Since the contact position of electrode plug and the electrode structure is in the lower part of first electrode intermediate plate and second electrode intermediate plate Close at the B of part, therefore when the lower end in contact of electrode plug close on part B be powered when, the ontology of electrode plug enters electricity substantially In the Socket casing of pole structure, exposed metal part is seldom.And traditional socket when using electrode plug contact electrode knot Exposed parts (when conventional socket has just been inserted into end) are larger when structure charges, therefore easily because exposed during plugging electrode plug Part is larger and human contact, and electric shock risk occurs, and the electrode structure effective solution of the application technical problem.With This simultaneously, the electrode structure of the application and electrode plug have biggish contact area, contact solid and reliable, have durable reliable The advantages of, it is ensured that preferable electric property.
