Abstract

The utility model discloses a roller-contact easy-pull socket which saves labor when inserting. A roller contacted with a clamping piece is arranged in the clamping piece of the socket. The clamping piece of a plug is inserted in the socket and is contacted with the roller in the clamping piece; the opposite moving of the two is in rolling friction which saves labor than the sliding friction of the prior art and achieves the goal of easily pulling out the plug. Only the roller and a pin are added in the novel socket, thereby simplifying the structure.

Description

Roller contacts easy plug seat

Technical field

The utility model is about a kind of socket, belongs to electric connector.Knowing clearly it, is that a kind of labour-saving roller that patches contacts easy plug seat.

Background technology

At present, in order to make known socket and plug excellent contact is arranged, generally all adopt elasticity electric conducting material preferably as far as possible, the slit of the intermediate plate of socket also makes narrowlyer as far as possible, closely contacts in the hope of the inserted sheet that makes intermediate plate and plug.Owing to when inserted sheet and intermediate plate relative motion, be sliding friction, so when plug is extracted socket, must exert oneself very much.In spite of oneself nail even finger are embedded between the plug and socket unplugg outward of exerting oneself sometimes.Such consequence is that finger might contact with the copper plug of plug, and the electric shock accidents that takes place.The people that strength is little can't pull the plug out of the socket at all.So some socket has to remove, prize the slit of intermediate plate widelyer, in order that when unplugg, more easily.But its possibility of result causes inserted sheet and intermediate plate to produce the consequence of loose contact.

Summary of the invention

In order to overcome the problem that existing socket is difficult for unplugg, the utility model provides a kind of socket, and this socket not only pulls the plug out of the socket easily, and the intermediate plate of the inserted sheet of plug and socket contact good.

The technical scheme that its technical problem that solves the utility model adopts is: it comprises intermediate plate, and roller is set in intermediate plate.When the inserted sheet of plug enters socket, contact with roller in the intermediate plate, are rolling friction during both relative motions, more laborsaving than the sliding friction of prior art, reached the purpose that easily pulls the plug out of the socket.

The beneficial effects of the utility model are: the plug plug is laborsaving than prior art, has guaranteed that simultaneously inserted sheet is good with contacting of intermediate plate.

Embodiment

Embodiment one: the contact condition that has shown the inserted sheet (1) of the intermediate plate (2) of existing socket and plug among Fig. 1 and Fig. 2.Intermediate plate (2) relies on the elasticity of metal material to clamp inserted sheet (1), keeps tight contact between the two.Inserted sheet (1) when extracting and intermediate plate (2) be sliding friction.The elasticity of intermediate plate (2) is good more, and extracting of inserted sheet will be required great effort.

(see that Fig. 3-Fig. 6) the utility model is that roller (3) is set in intermediate plate (2).Intermediate plate (2) and roller (3) link together with pin (4).Roller can rotate around pin (4).Roller (3) not only contacts with intermediate plate (2), also contacts with inserted sheet (1).Inserted sheet (1) is when extracting, with roller (3) be rolling friction.So it is when the plug sheet, more laborsaving than the sliding friction of prior art.Fig. 6 has shown the schematic diagram of the inner principal character of the utility model Three-hole socket.Two spring hole scokets are not repeated with this reasoning.

Embodiment two: (see that Fig. 7-Fig. 9) makes cost of the present utility model in order to reduce, can be processed into intermediate plate (2) by Sheet Metal Forming Technology the shape of Fig. 7-Fig. 9, roller (3) can be arranged in the roller slot that is stamped to form (5) of intermediate plate, and can roll in roller slot (5).Its manufacturing cost is cheaper than embodiment one.

Claims

1, a kind of roller contacts easy plug seat, and it comprises intermediate plate, it is characterized in that being provided with in intermediate plate roller.

2, roller as claimed in claim 1 contacts easy plug seat, it is characterized in that described roller is connected with pin with intermediate plate.

3, roller as claimed in claim 1 contacts easy plug seat, it is characterized in that described roller can be arranged in the roller slot of intermediate plate.
