Embodiment

Below the preferred embodiment of the present invention is carried out concrete reference, in the accompanying drawings embodiment is described.Yet the present invention can comprise multiple different form and can not be interpreted as by execution mode described here and limits.

With reference to Fig. 6 and Fig. 7, the bullet connector (plugconnector) that is used for mobile communications device according to the present invention is the parts of the connector (socket connector) 100 that removably is inserted into mobile communications device.Described connector 100 is coupled to the PCB of mobile communications device, and bullet connector is coupled to the PCB1 of the device that will be connected with mobile communications device.

Referring to figs. 1 through 7, the bullet connector that is used for mobile communications device according to one embodiment of the present invention comprises many contact pilotages 10, and predetermined interval is arranged between contact pilotage, supports the insulator 20 of contact pilotage 10 and the shell 30 of wrap insulate body 20.

Contact pilotage 10 comprises the pin main body 11 that is supported by insulator 20, the arm 12 that extends from the front end of pin main body 11, the wrist (wrist) 13 that forms at the front end of arm 12 in the mode of shrinking, contact portion 14 of extending from the front end of wrist 13 and the rear end sweep 15 that extends from the rear end of pin main body 11.

Bullet connector according to the embodiment of the present invention has the contact pilotage that 20 (10 * 2) root altogether contacts with PCB.

Pin main body 11 is coupled by insulator 20 and jag.Pin main body 11 has block (stopper) 11a that forms protrusion from it, so contact pilotage 10 can support PCB and can not discharge to PCB.

Contact portion 14 contacts with the contact 110 of connector 100.Between arm 12 and contact portion, form wrist 13, when contacting with the contact 110 of connector 100, improve exposure level with convenient contact portion 14 in the mode of shrinking.

Make arm 12 elastically-deformable so that contact portion 14 can contact with the contact 110 of connector 100.

Insulator 20 comprises the needle socket 21 that is used to receive contact pilotage 10, and this needle socket 21 within it wall have corresponding to contact pilotage 10 formed a plurality of grooves 22.

End in the contact portion 14 of inserting groove 22 forms downward-sloping targeting part 16.

Targeting part 16 is formed at an end of contact portion 14, and it is downward-sloping when being inserted into groove 22 with box lunch, and contact pilotage always is coupled with insulator 20.That is to say that targeting part 16 always leads contact pilotage 10 when contacting with the contact 110 of connector 100 with convenient contact portion 14, contact pilotage will never laterally move, and when contact pilotage 10 was inserted into groove 22, contact portion 14 did not contact with contact 110 yet.Therefore, can avoid between contact pilotage 10 and adjacent contact pilotage 10, being short-circuited.

At this, formation exceeds wrist 13 along the vertical linearly extended

arm

12 and 14 of the contact portions of pin main body 11, and does not in fact exceed arm 12; Simultaneously, targeting part 16 is outstanding downwards from the front end of the contact portion 14 lower than wrist 13.

Therefore, when the contact 110 of connector 100 was inserted into needle socket 21 and contacts with contact portion 14, arm 12 and contact portion 14 minimized with respect to the moment of pin main body 11, therefore can avoid causing the deformation of contact pilotage 10 wrong contacts.

That is to say that contact portion 14 and targeting part 16 be along almost extending and form with respect to 12 one-tenth lines of arm, and the direction of insertion of the contact 110 of described line stretcher and connector 100 to have a minimum constructive height poor, therefore can minimize moment.

The rear end sweep 15 of contact pilotage 10 is outwards outstanding so that pin main body 11 can be arranged on the center of insulator 20 from insulator 20.This has reduced the height tolerance between the contact 110 of the direction of insertion of arm 12 of contact pilotage 10 and connector 100.

Bending direction according to rear end sweep 15 is divided into the first contact pilotage 10a and the second contact pilotage 10b with contact pilotage 10.The described first contact pilotage 10a is to the upper surface bending of PCB1, and the second contact pilotage 10b is to the lower surface bending of PCB1.

The first contact pilotage 10a not only is electrically connected to the upper surface terminals, and supports the upper surface of PCB1, and the second contact pilotage 10b not only is electrically connected to the lower surface terminals of PCB1, and supports the lower surface of PCB1.

Although the rear end sweep 15 of the first contact pilotage 10a and the second contact pilotage 10b is with opposite direction bending, pin main body 11 all is coupled on the insulator 20 at equal height.As mentioned above, each rear end sweep 15 of the first contact pilotage 10a and the second contact pilotage 10b is projected into insulator 20 outsides, so that every pin main body 11 can be arranged on the center of insulator 20.Just arm 12 is navigated to the center of needle socket 21.Therefore, the insertion of the contact 110 of the height of arm 12 and connector 100 highly much at one.

The outer surface of insulator 20 supports rear end sweep 15, moves to needle socket 21 so that prevent contact pilotage 10.

Shell 30 comprises housing 31 and is used to support the substrate holder of PCB1 outer surface.

The outside of housing 31 coated insulation bodies 20 is to increase the intensity of insulator 20.
