Abstract

The utility model discloses an error-proof socket connector. One end of a male plug is plugged and cooperated with a wiring port of a female socket, the male plug is provided with a hook-shaped convex tip, the surface where the hook-shaped convex tip is arranged is provided with a projection, the projection is arranged in the direction in which the male plug is inserted into the female socket, a block is arranged on a casing, the wiring port comprises a bottom portion and a sidewall which is arranged around the bottom portion, and the sidewall is provided with a groove which is plugged and cooperated with the projection. According to the utility model, when the male plug is inserted into the female socket, the projection which is arranged on the male plug is cooperated with the groove in the sidewall of the wiring port of the female socket, thereby preventing that a contact surface of the female socket is plugged in the wrong direction.

Description

A kind of anti-misconnection plug-in unit

Technical field

The utility model relates to the field of interconnect technologies of electronic circuit, especially a kind of connector for mistake proofing.

Background technology

At present, general connector wrong plug design is different connectors design difformities, and when the line number of connector is a lot, effect is pretty good, but in the less situation of line number, easily produces positive and negative grafting mistake.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of anti-positive and negative wrong plug connector of pegging graft.

For achieving the above object, the utility model provides following technical scheme: a kind of anti-misconnection plug-in unit, comprise public plug, mother socket and buckle assembly, described public plug is connected by buckle assembly with mother socket, described buckle assembly comprises hook-shaped spur and for the fixture block with hook-shaped spur clamping, described mother socket comprises shell and connection jaws, peg graft and coordinate with mother socket connection jaws in described public plug one end, described hook-shaped spur is located on public plug, the one side that described public plug is provided with hook-shaped spur is provided with projection, described projection arranges along public plug and mother socket grafting direction, described fixture block is located on shell, described connection jaws comprises bottom, and along the sidewall of bottom winding, described sidewall is provided with the groove of pegging graft and coordinating with projection.

By adopting technique scheme, when public plug and mother socket are pegged graft, by being arranged at the groove on connection jaws sidewall on projection on public plug and mother socket, prevented the grafting mistake of mother socket grafting contact-making surface both forward and reverse directions in public plug and mother socket grafting process.

The utility model is further set to: described public plug is provided with block with respect to the other end of mother socket.

By adopting technique scheme, block is located at the other end of relative mother socket, the setting party of block to projection setting party to perpendicular, during grafting, block can play barrier effect when the whole insertion mother socket of public plug.

The utility model is further set to: described fixture block and mother socket are one-body molded.

The utility model is further set to: described hook-shaped spur and projection are all integral moulding with public plug.

By adopting technique scheme, projection and mother socket are one-body molded, and hook-shaped spur and projection are all integral moulding with public plug, have reduced making material, and technical process, have reduced cost of manufacture.

Accompanying drawing explanation

Fig. 1 is the utility model grafting schematic diagram.

In figure: 1, mother socket; 11, fixture block; 12, connection jaws; 13, groove; 2, public plug; 21, hook-shaped spur; 22, projection; 3, block.

Embodiment

Shown in Fig. 1, a kind of anti-misconnection plug-in unit of the present embodiment, comprise public plug 2, mother socket 1 and buckle assembly, described public plug 2 is connected by buckle assembly with mother socket 1, described buckle assembly comprises hook-shaped spur 21 and for the fixture block 11 with hook-shaped spur 21 clampings, described mother socket 1 comprises shell and connection jaws 12, peg graft and coordinate with mother socket 1 connection jaws 12 in described public plug 2 one end, on one end that described hook-shaped spur 21 is located on public plug 2 and is plugged with connection jaws 12, described public plug 2 is provided with projection 22 with respect to the one side of hook-shaped spur 21, described projection 22 arranges along public plug 2 and mother socket 1 grafting direction, described fixture block 11 is located on shell, described connection jaws 12 comprises bottom, and along the sidewall of bottom winding, described 12 sidewalls are provided with the groove 13 of pegging graft and coordinating with projection 22.

By adopting technique scheme, when public plug 2 is pegged graft with mother socket 1, by being arranged at the groove 13 on connection jaws 12 sidewalls on projection on public plug 2 22 and mother socket 1, prevented the grafting mistake of mother socket 1 grafting contact-making surface both forward and reverse directions in public plug 2 and mother socket 1 grafting process.

Described public plug 2 is provided with block 3 with respect to the other end of mother socket 1.By adopting technique scheme, block 3 be located at respect to the other end of mother socket 1 and with the end face setting that becomes to align, the setting party of block 3 to projection 22 setting parties to perpendicular, during grafting, block 3 can play barrier effect when the whole insertion mother socket 1 of public plug 2.

Described fixture block 11 is one-body molded with mother socket 1; Described hook-shaped spur 21 and projection 22 are all integral moulding with public plug 2.

By adopting technique scheme, projection 22 is one-body molded with mother socket 1, and hook-shaped spur 21 and projection 22 are all integral moulding with public plug 2, have reduced making material, and technical process, have reduced cost of manufacture.

The above is only preferred implementation of the present utility model, and protection range of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
