Abstract

The invention relates to a shedding preventing plug connector, which belongs to an electrically-connected plug socket and mainly comprises a socket and a plug. The socket is formed by fixing an insulated socket cover at an insulated socket bottom; two fixed contacts are arranged at the insulated socket bottom, wherein each contact has a structure that: one end of a contact piece is fixed at the insulating socket, while the other end is supported on a spring which is fixed on the insulated socket bottom, and the contact piece is wavy; corresponding positions of the insulated socket cover and the contact piece are provided with openings and seam ports; and the plug structure is as follows: an insulated block is fixedly connected with two moving contacts, wherein each moving contact is hemispherical and used for being movably inserted into the opening of the insulated socket cover, so that the moving contacts are reliably contacted with the contact piece. The shedding preventing plug connector has the advantages of reliable electric connection, unsusceptible shedding and favorable safety.

Description

Shedding preventing plug connector

Technical field

The present invention relates to the plug connector that is used to be electrically connected, particularly have the technical field of the plug and the socket of slip-off preventing function.

Background technology

Current, household electric appliances and small-sized electric instrument often pass through plug insertion socket, for equipment provides electric energy, loose contact, heating damage socket and plug appear easily, in addition, plug is extracted socket easily, when plug did not separate fully with socket, plug metal part branch exposed, and child's finger can stretch into, cause short circuit or electric shock, if plug separates suddenly with socket, can cause the electric equipment sudden power, influence its operate as normal.

Summary of the invention

The purpose of this invention is to provide that a kind of plug is not easy to come off, the better shedding preventing plug connector of fail safe.

The object of the present invention is achieved like this: a kind of shedding preventing plug connector, mainly to form by socket and plug, and socket constitutes on being fixed at the bottom of the insulated receptacle by insulated socket cover; Be provided with two fixed contacts at the bottom of the insulated receptacle, each static contact structure is: at the bottom of the insulated receptacle, the other end is bearing on the spring contact chip one end through screw, and on spring is fixed at the bottom of the insulated receptacle, and contact chip is wavy; The correspondence position of insulated socket cover and contact chip is provided with perforate and sealing; Described plug construction is: be fixedly connected with two moving contacts on the collets, each moving contact is shaped as hemispherical, is used for inserting versatilely on the socket cover in the perforate (and slide along sealing) and moving contact is reliably contacted with contact chip.It has and is electrically connected reliable, difficult drop-off, advantage that fail safe is good.

Compared with prior art, the invention has the beneficial effects as follows:

1, reliability is higher, fail safe is better

Slip-off preventing socket and plug of the present invention, in application process, plug can not separate with socket easily, prevent sudden power, necessary, plug pulled out could realize to socket circular hole place separating, in this process, can not occur causing short circuit or electric shock because of current-carrying part exposes.

2, novel structure, low cost of manufacture.

Embodiment

In the accompanying drawing, 1, at the bottom of the insulated receptacle; 1a, contact chip; 1b, spring; 2, insulated socket cover; 2a, (socket cover) perforate; 2b, (socket cover) sealing; 3, plug; 3a, collets; 3b, moving contact.

Slip-off preventing socket and plug of the present invention is made up of socket back, socket cover and plug.

Socket back is made by insulating material; Be provided with contact chip in it, contact chip has certain thickness, satisfies the operating current needs, undulate, prevent plug on contact chip from line slip; One end is realized connecting by screw and lead and is fixing, and the other end is guaranteed to contact well with plug by spring-loaded.

Socket cover is made by insulating material; Its thickness is suitable mutually with the flat director's degree of plug; Corresponding with contact chip, the power supply approaching side is provided with and the suitable circular hole of plug; Along the contact chip fluting, length is suitable mutually with contact chip between circular hole and the contact chip spring, and width is suitable mutually with the flat place of plug thickness.

Plug is made up of current-carrying part and insulated part, and current-carrying part is made by metal material, and an end has screw, connects mutually with lead by screw, and is located in the insulated part, and the other end is hemispherical, is flat between the two ends.

For preventing to install switch additional, or in lid, install additional and block adhesive tape, or on socket cover, establish seal cover etc. by socket cover contact contact chip or waterproof.

The using method of slip-off preventing socket and plug: after socket, plug and wire coupling were reliable, hand-held plug insulated part with the corresponding socket cover circular hole place that inserts of the hemispherical current-carrying part of plug, moved plug again along the socket cover fluting other end, pull out motionless getting final product.

Claims

1. a shedding preventing plug connector mainly is made up of socket and plug (3), it is characterized in that: (1) went up formation at the bottom of described socket was fixed on insulated receptacle by insulated socket cover (2); (1) is provided with two fixed contacts at the bottom of the insulated receptacle, each static contact structure is: contact chip (1a) end through screw on (1) at the bottom of the insulated receptacle, the other end is bearing on the spring (1b), and spring (1b) is fixed at the bottom of the insulated receptacle on (1), and contact chip (1a) is wavy; Insulated socket cover (2) is provided with perforate (2a) and sealing (2b) with the correspondence position of contact chip, and the perforate of insulated socket cover is corresponding with an end of contact chip, and sealing is corresponding with the contact chip remainder; Described plug (3) structure is: be fixedly connected with two moving contacts (3b) on the collets (3a), each moving contact is shaped as hemispherical, be used for inserting versatilely in the perforate on the socket cover (2a), moving contact (3b) is reliably contacted with contact chip (1a), plug is except that having moving contact, also have flat place and be used to connect moving contact and plug collets, sealing length is suitable mutually with contact chip, width is suitable mutually with flat place thickness, thereby make the corresponding socket cover circular hole place that inserts of the hemispherical current-carrying part of plug, plug can be moved along the socket cover sealing other end, pull out motionless getting final product.
