Abstract

The invention relates to an electric connector which provides a more reliable connecting relationship with an object on the other end and comprises a shell and at least two terminals arranged in the corresponding positions, wherein each terminal is provided with a contact end and a conduction end; the conduction end is connected with an external circuit, and the contact end is connected with the object on the other end; a turning part is arranged between the contact end and the conduction end; and when the conduction end is fixed, the contact end is elastic. The contact end is accommodated inthe shell; the free end of the contact end forms a bent part bending towards an inner wall of an adjacent shell; and after being assembled with the shell, the end of the bent part is pressed by the inner wall of the shell to form precompression towards the direction of the terminal on the opposite end so that a good conductive connecting relationship is formed by increasing gripping force to the connecting object on the other end.

Description

Electric connector

Technical field

The present invention is a kind of electric connector, and particularly a kind of and other end connecting object have more certain connector that contacts with the conducting relation.

Background technology

The function of electric power connector is providing separable interface, two subsystems (or device) that connect electronic system inside, its significant feature mode, be by connector and this system (or device) when assembling mutually, the forward contact force that produces at contact interface, thus reach the purpose of transmitting signal.

Fig. 1 is a kind of prior art of the connector for the light source lamp tube wire, and it mainly provides lead 20 connected modes of a kind of electric connector 1 with fluorescent tube 2, and the terminal 10 by described electric connector 1 inside contacts the purpose that reaches the transmission signal with lead 20.

The disclosed terminal 10 of Fig. 1, by base 101 and the upwardly extending holder 102 of two side ends thereof, 103 constitute, by the lead 20 that base 101 passes, the signal of fluorescent tube 2 is linked up by two holders 102,103 clampings by this electric connector 1 and external device (ED); The defective that it constitutes clearly is the chucking power deficiency that described terminal 10 provides, particularly in order to the lead 20 of clamping jewelry, expensive clothing and other valuables, and phenomenon such as easily form loose contact or come off.

Summary of the invention

The electric connector that the present invention is designed is mainly the annexation that provides more certain with other end connecting object.

Electric connector comprises: shell and at least two are located at relative position and the shape terminal of symmetry each other, wherein:

Described shell has top, bottom and the sidepiece between top and bottom, the inside of described shell has first room that contains described terminal, this first room extends wide second room littler than described first room in footpath towards the top-direction of described shell, and the bottom of described shell has the hole that connects this first room;

Terminal has contact jaw and conduction terminal, and conduction terminal is connected with external circuit, and contact jaw is connected with other end connecting object, has the turning point between contact jaw and the conduction terminal, and conduction terminal is fixedly the time, and contact jaw has elasticity; Described contact jaw is compatible in the shell, its free end forms the pars convoluta towards the bending of adjacent shells inwall, after the shell assembling, the terminal of described pars convoluta is subjected to compressing of outer casing inner wall, formation is towards the precompression of the terminal direction of opposite end, so as to increasing the chucking power to other end connecting object, be purpose of the present invention.

Borrow above-mentionedly, the present invention produces useful effect: provide a kind of more stable contact to other end connecting object, particularly for example the little lead in line footpath that discloses of prior art obtains this effect too.

Embodiment

Please refer to Fig. 2 and Fig. 3, the present invention mainly comprises: shell 3 and at least two terminals 4,5 of being located at relative position, wherein:

Described shell 3 is made by a kind of insulating material, has top 30, bottom 31 and the sidepiece 32 between top 30 and bottom 31; The inside of shell 3 has contains terminal 4,5 first room 33, first room 33 extends the wide second less room 34 in footpath towards top 30 directions of shell 3, and the bottom 31 of shell 3 has the hole 35 that connects first room 33, and the connecting object of the confession other end enters thus with terminal 4,5 and contacts.Please also refer to Fig. 5, in disclosed embodiment, described other end connecting object is lead 6.In addition, respectively has holding slot 36,37 (as shown in Figure 3) at first room, 33 two relative madial walls, respectively in order to locate aforesaid two terminals 4,5.

Described two terminals 4,5 are made by a kind of metallic conduction material, and its shape is symmetry each other.Lift one of them terminal 5 and be example, have contact jaw 50 and conduction terminal 51, conduction terminal 51 is connected with external circuit 7 (as shown in Figure 5), and contact jaw 50 is connected with other end connecting object (being aforesaid lead 6); As shown in Figure 2, have turning point 52 between described contact jaw 50 and the conduction terminal 51, fixedly the time, contact jaw 50 has elasticity in conduction terminal 51.The free end of described contact jaw 50 forms towards the pars convoluta 53 of the inwall bending of adjacent shells sidepiece 32, and two terminals 4,5 pars convoluta 43,53 corresponding surfaces respectively are provided with arc groove 431,531, in order to suppling wire 6 contacts and increase the area that contacts with each other.

During assembling, please also refer to Fig. 4, the conduction terminal 51 of terminal 5 is positioned at the holding slot 36 of aforementioned shell 3, contact jaw 50 is exposed in first room 33 of shell 3, again with top 30 sliding push away of terminal 5 towards shell, make the contact jaw 50 of terminal 5 enter second room 34, in this trip, because the wide h1 in footpath of aforementioned second room 34 is less than first room 33, make described termination contact end 50 distortion, and the terminal 532 of pars convoluta 53 is compressed by second room, 34 contiguous inwalls 341, forms towards the forward precompression of terminal 4 directions of opposite end; Please also refer to Fig. 5, at lead 6 in the hole 35 of shell 3 bottoms 31 penetrates and enters arc groove 431,531 between two terminals 4,5, contact jaw 40 that can be by described two terminals, 50 chucking power and by stable fixing.

More than aforementioned only be preferred embodiments of the present invention, from not limiting the scope of its claim with this.Such as have equivalence modification or the variation of knowing that usually the knowledgeable hence does according to spirit of the present invention in the affiliated technical field, all still be covered by in the scope of claims.
