Embodiment
Please with reference to the preferred embodiment shown in Fig. 1 to 9, the present invention provides a kind of electric connector 1 can use with flexible transmission unit 6 to link each other, and electric connector 1 mainly comprises insulating body 2, two fasteners 3, several conducting terminals 4 and metal shell 5.
Two fasteners 3 are hubbed at respectively in the groove 28; Each fastener 3 is provided with a contact site 31, an articulated section 32 and a retaining and leans on portion 33; Articulated section 32 is in order to leaning between the portion 33 as the axle center of fastener 3 rotation starts and at contact site 31 and retaining, and contact site 31 is provided with one and extends to the interior stop portion 310 of accommodation space 20.Articulated section 32 is hubbed in the groove 28, and contact site 31 is positioned at groove 28 and is adjacent to accommodation space 20, and stop portion 310 is arranged on the contact site 31 and extends in the accommodation space 20, and retaining leans on portion 33 to be positioned at groove 28 and to be adjacent to resilient portion 53.
Several conducting terminals 4 are installed in the terminal slots 26 of insulating body 2; Conducting terminal 4 has one and is positioned at the contact jaw 41 of accommodation space 20 and extends the welding ends of starting from outside the insulating body 2 42; Contact jaw 41 can electrically contact with the flexible transmission unit 6 in inserting accommodation space 20 each other, and 42 of welding endss are fixedly welded on the external circuit board (not shown).
In the present embodiment; The contact site 31 of fastener, articulated section 32, stop portion 310 and retaining lean on portion 33 for plastics penetrate integrated structure, retaining leans on portion 33 to be provided with a protuberance 330, protuberance 330 is intended for resilient portion 53 settings; Being beneficial to protuberance 330 application of forces is resisted against resilient portion 53 and makes it produce strain; Articulated section 32 is leaned between the portion 33 at contact site 31 and retaining, and the end that is adjacent to contact site 31 is provided with stop portion 310, is adjacent to retaining and leans on the end of portion 33 that protuberance 330 is set; Wherein protuberance 330 distance in the articulated section 32 length less than stop portion 310 distances in the articulated section 32 length, so can let the operator obtain the effect of application of force effect preferably.
When flexible transmission unit 6 was inserted in the accommodation space 20, stop portion 310 can be interfered the breach 62 in flexible transmission unit 6, so as to reaching the purpose that flexible transmission unit 6 is fixed in electric connector 1.During practical operation; The user can finger presses in elastic operation portion 51; Pressure section 52 can and then move down and press on contact site 31 together; And make stop portion 310 be the axle center with articulated section 32 to move to a unlocked position and be away from breach 62 from latched position rotation, this moment, retaining leaned on portion 33 application of forces to be resisted against on the resilient portion 53.When unclamping elastic operation portion 51; Pressure section 52 can be away from contact site 31; This moment, resilient portion 53 provided elastic reactance to lean in the portion 33 in retaining, so that stop portion 310 moves to latched position and engages with breach 62 so that be the axle center from unlocked position rotate in articulated section 32.
Therefore when operator's desire is inserted or take out flexible transmission unit 6; Can push elastic operation portion 51 earlier; Make stop portion 310 rotations move to unlocked position, insert or extract flexible transmission unit 6 again, then unclamp elastic operation portion 51 again; Make stop portion 310 rotations move to latched position, to reach the purpose of locking or release flexible transmission unit 6.In addition, because stop portion 310 itself has the design of guiding incline,,, also can reach the purpose that breach 62 location is sticked in stop portion 310 even not according to compression elasticity operating portion 51 therefore in the stage of inserting flexible transmission unit 6.
In the present embodiment; The opening of accommodation space 20 is positioned at insulating body 2 front sides, and the opening of groove 28 is positioned at insulating body 2 rear sides, and contact site 31 is towards the opening direction extension of accommodation space 20; Retaining leans on portion 33 to extend towards the direction perpendicular to contact site 31 in principle; What for example Fig. 3 appeared is L shaped, so is not limited thereto, and contact site 31 leans on the junction of portion 33 to form articulated section 32 with retaining.In addition, the bearing portion 29 of present embodiment is a concavity structure, and articulated section 32 so is not limited thereto for being coupled in a convex structure of bearing portion 29, and the shape and structure of coupling is also interchangeable between the two, as long as can reach the purpose of pivot.
Be provided with several location protection portions 21 in addition in the upper surface place of insulating body 2; Functions of this a little location protection portion 21 be to protect elastic operation portion 51 and and upper casing 502 between the elastic joint part branch; Destroy to avoid receiving external force collision, and can locate the stroke space of elastic operation portion 51.
In sum; Electric connector of the present invention is pivoted with a fastener on insulating body; Rotation up and down by this fastener of control is moved; Reach the fixedly purpose of flexible transmission unit; This kind rotates up and down and moves the reliability that fixing mode more can not have influence on the electric connection between flexible transmission unit and the conducting terminal, and it is not good therefore can to solve the reliability that electrically connects between flexible flat cable that existing electric connector is easy to generate and the conducting terminal, and what caused is easy to generate the problem that the visitor tells.In addition; Electric connector of the present invention also is provided with several grounding elastic parts on metal shell; The slit that forms between these a little grounding elastic parts and several conducting terminals is except can be used to seize on both sides by the arms the flexible transmission unit; Can also reach the purpose that grounding elastic part closely is overlapped in the metal level on the flexible transmission unit; So not only can reach between flexible transmission unit and the conducting terminal firmly outside the electrical connection, can also see through the grounding parts ground connection of metal shell, reach the effect that prevents the external electromagnetic wave interference.
The above for the person of ordinary skill of the art, can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection range of claim of the present invention.
