Abstract

The present invention relates to an electric connector. The locking characteristic of the electric connector is explained clearly, and in a word, the present invention provides an improvement to a latch arm (25). The latch arm utilizes a groove (24) on the outer wall of a plug end (20) on the electric connector and can rotate on one end, and thereby, the latch arm is elastically bent on the bottom surface of the groove. A socket end (10) is provided with a locking body (18) which can be engaged with part of the latch arm, and the plug end and the socket end can be locked separately.

Description

Electric connector

The present invention relates to improvement to a kind of electric connector.

Recently, people wish to have a kind of electric connector, can be installed on the small-sized electric equipment and electronic instrument, and this connector can make the miniaturization more that becomes more lightly of electric equipment or electronic instrument, and this just requires the position of connector mounting little.

In the Japanese Utility Model registration number is that 1333825(utility model publication No. is 53-12458), comprise among Fig. 2 of disclosed a kind of electric connector: a plug portion and the socket part that can work in coordination.On its plug portion, be provided with a door bolt arm, one locking projection arranged in door bolt arm outside.This door bolt arm is placed in the groove in the plug outer wall, and an end is fixed and makes its resilient bending on groove bottom.On the other hand, socket part has the locking part of an oblique protrusion; When plug portion was inserted into socket part, it was meshed with the locking projection of door bolt on the arm, thereby separably two parts is pinned.

An advantage of known above-mentioned electric connector is: its door bolt arm is installed in the groove of making on the plug portion outer wall, and the overwhelming majority of door bolt arm is suitable for the internal cavity of socket part, so the power of outer surface can not influence the door bolt arm.Yet, in addition on the one hand, be how to make the littler problem of electric connector below door bolt arm configuration among the 53-12458 exists in the Japanese Utility Model publication No..In other words, in electric connector, the door bolt projection that is provided with on the door bolt arm, protrusion above plug body, consequently socket also needs one and can hold the space of fastening projection with a bolt or latch except the space that adapts to plug portion, and therefore, the shape of socket part must be able to form a space, its height will adapt to the height of plug body, with the total height of door bolt bump height addition.So just make electric connector have bigger profile.

Purpose of the present invention will provide a kind of electric connector exactly, makes the door bolt arm of this electric connector littler than known electric connector by improving its door bolt arm, also can avoid its circuit to twine simultaneously.

Further purpose of the present invention is designed a kind of plug end part that has exactly, and socket end electric connector partly that plug end is partly inserted, it is characterized in that plug end partly has a door bolt arm that is provided with the door bolt projection, this door bolt arm is placed in the groove of making on the outer wall of plug end part, and the one end is fixedly made its resilient bending on groove bottom, and then one locking part is partly arranged in socket end, when plug end is partly inserted the receptacle ends timesharing, door bolt disconnected from each other on two connectors meshes in the door bolt projection of door bolt arm.And feature is: groove set on the door bolt arm extends on door bolt arm longitudinal direction, and a door bolt projection is wherein arranged.

According to concrete equipment of the present invention, and the following relevant accompanying drawing of reference is illustrated.

Fig. 1 is the perspective view of the electric connector under the insertion state not among the present invention.

The sectional drawing of the 11-11 position in Fig. 2 presentation graphs 1.

Fig. 3 is illustrated among Fig. 2 the sectional drawing under the insertion state.

This electric connector is by a socket end part 10, and plug end part 20 formations that energy matches with socket end 10.This electric connector is to make with a kind of plastic mould pressing of insulation.

Socket end part 10 has a cavity part 16, and its scope is by upper wall 11 and lower wall 12, left side wall 13 and right side wall 14, and rear wall 15 limits.Have manyly,, through rear wall 15, and be fixed on the rear wall from cavity part 16 parallel stretching out to the contact chip 17 that goes between up and down.Each contact chip 17 all has a leg 17a protruding and at an angle of 90 crooked so that below stretching to from rear wall 15.The leg 17a of contact chip can insert downwards in the hole of printed circuit board (PCB), not shown this printed circuit board (PCB) on the figure.

Be provided with an engagement projection 18 in the front portion of upper wall 11 inner surfaces, this projection has the anterior 18a of inclination and vertical rear portion 18b.

Plug end part 20 has many by sidewall 23 separated contact cavitys 21, so that match with a pair of contact base 22 up and down, this socket 22 can be inserted in a pair of contact chip 17 that goes between up and down in the socket end part 10.

A groove 24 that extends back from electric connector insertion surface is arranged at the top of plug end part 20.Be provided with a door bolt arm 25 in groove 24, its front end is fixed on the front end of the sidewall 24a that passes through transverse arm 25a, so that door bolt arm 25 can be flexibly crooked at stiff end.

It is in order to put in backward the groove 24 from stiff end, so that the upper surface and the plug end body of door bolt arm 25 combine jointly that door bolt arm 25 is set.Back free end at door bolt arm 25 has a button 26 that protrudes upward through groove 24.Door bolt arm 25 also has a groove 27, and this groove 27 is at the fixedly front end surface longitudinal extension of door bolt arm 25; And a door bolt projection 28 is arranged in the middle part of this groove.

The shape of groove 27 is in order to make it have width " W " so that the engagement projection 18 of socket end part 10 can insert.Therefore, when plug end part 20 matches with socket end part 10, groove 27 will guide socket end part 10 to match with engagement projection 18 by groove 27 as a guider exactly.

Door bolt projection 28 stretches out from the baseplane 27a of groove 27, has one to limit the frontal plane 28a and vertical back plane 28b of inclination, and finishes at the upper surface place of door bolt arm 25.

In the said structure that socket end part 10 and plug end part 20 match, connector is configuration like this, it is the front surface of plug end part 20, cavity part 16 facing to socket end part 10, and when plug end part 20 is inserted socket end part 10, the engagement projection 18 of socket end part 10 pushes along the groove 27 of fastening arm 25 with a bolt or latch; And make the inclined plane 28a of the forward part 18a of inclination near door bolt projection 28, make of the bottom surface bending of door bolt arm towards groove 24.When these two connectors further cooperate, and when meshing projection 18 and then being pressed into door bolt arm 25, engagement projection 18 will be climbed up door bolt projection 28, the elasticity of fastening arm 25 simultaneously with a bolt or latch makes it rotate back into the vertical plane 28b that the home position causes the vertical back portion 18b embedding door bolt projection 28 of engagement projection 18, and two connectors are fastened mutually.Otherwise opening of these two connectors can be finished by the button of depressing on the door bolt arm 25 26, makes engagement projection 18 deviate from from door bolt projection 28, and a connector is pulled out from another connector.

In sum, according to this structure of the present invention, be that the door bolt projection of door bolt arm is placed in the groove of door bolt arm, it is not stretched out from the top of plug end body, therefore socket end partly need not to adapting to door bolt projection slot milling, so, can make a kind of electric connector littler than known electric connector.Simultaneously, when two connectors cooperate, the door bolt projection is climbed up the engagement projection, and when the door bolt arm bounces back into its home position, in the inner surface of the equal indentation socket end part of the upper surface of whole door bolt arm, then send loud click, make operating personnel can know easily that two connectors insert fully.
