The content of the invention

The purpose of the application is to provide the conducting terminal and lead using this that a kind of height dimension is smaller and elastic force is good The electric connector of electric terminal.

Therefore, this application provides a kind of conducting terminal, including base portion, the drawing from the formation of base portion rear end inverse bending Extension that tight portion, the extension that is inclined upwardly from the tightening part end are formed, the contact site for being formed at the extension end and From the contact site is towards base portion direction bending and extension forms abutting part, the base portion is in the correspondence abutting part position Place processes the depressed part to lower recess by punching stretch technique, and the abutting part is being pressed down against to the mistake of working condition Cheng Zhong, the abutting part is slided on the depressed part deforms and is provided jointly with tightening part the elasticity for supporting the contact site Power, the bottom surface of the depressed part is welded on printed circuit board (PCB) as weld part.

Therefore, present invention also provides a kind of electric connector, including insulator foot, it is shaped in the insulator foot Some conducting terminals, insulation cover plate and the retaining piece being shaped between the insulator foot and the insulation cover plate, institute Conducting terminal is stated including base portion, from the tightening part of base portion rear end inverse bending formation, from the tightening part end to updip Extension that tiltedly extension is formed, it is formed at the contact site of the extension end and from the contact site towards the base portion side To bending and extend and form abutting part, the base portion at the correspondence abutting part position by punching stretch technique process to The depressed part of lower recess, the abutting part is during being pressed down against to working condition, and the abutting part is in the depression Slided in portion and deform and provided jointly with tightening part the elastic force for supporting the contact site, the bottom of the depressed part of the conducting terminal Face is welded on printed circuit board (PCB) as weld part.

Compared to prior art, the technical scheme of the application possesses following beneficial effect：By in the conducting terminal Base portion corresponds to punching press at the abutting part position and is recessed to form the depressed part that the confession abutting part slides against, and makes the abutting part Slide against in providing elastic force together with the tightening part for the contact site on the depressed part, meanwhile, make the abutting Portion makes full use of the lower sounding for the depressed part being recessed to below the insulator foot in the case where being not required to scrape printed circuit board (PCB) Between, greatly reduce the overall work height of electric connector.

Embodiment

Refer to shown in Fig. 1 to Fig. 3, the electric connector of the application includes insulator foot 10, takes shape in the insulator foot Some conducting terminals 40, insulation cover plate 30 in 10 and be shaped in the insulator foot 10 and the insulation cover plate 30 it Between retaining piece 20.

The insulator foot 10 is in list structure, and some terminal grooves 11 for accommodating the conducting terminal 40 are formed with thereon, The conducting terminal 40 is molded to form the insulator foot 10 through in-mould injection, and the upside of the insulator foot 10 is formed with receiving Position the locating slot 12 of the retaining piece 20.Then, the retaining piece 20 is assemblied in the locating slot 12, and carried out again Injection molding is operated, and forms the fixing retaining piece 30 in interior insulation cover plate 30.The retaining piece 20, the correspondence of insulation cover plate 30 Terminal groove 21,31 is similarly formed at the position of the terminal groove 11.Four edges extension of the retaining piece 20 is formed with Leg 22 is to strengthen the fixing power between the electric connector and printed circuit board (PCB).

The conducting terminal 40 includes base portion 41, from the tightening part 43 of the rear end inverse bending formation of the base portion 41, from institute State tightening part 43 and tilt upward the extension 44 of extension formation, the contact site 45 for being formed at the end of extension 44, described in The ends bent of contact site 45 extends the abutting part 46 formed towards the base portion 41 and the confession institute formed that is recessed from the base portion 41 State abutting part 46 and abut the depressed part 42 slided.

The outer rim of base portion 41 of the conducting terminal 40 is shaped in the insulator foot 10, and the tightening part 43 is laterally Both sides be additionally provided with the side 47 that takes shape in the insulator foot 10 so that the conducting terminal 40 and the insulator foot 10 it Between reach maximum fixing power.

The depressed part 42 be from the base portion 41 correspondence position of abutting part 46 by way of punching stretch structure Formed into part decanting zone, when the stress of contact site 45 is deformed downwards, the abutting part 46 can be in the depressed part 42 The upper elastic force slided deformation and the support contact site 45 is provided jointly with the tightening part 43.The bottom surface of the depressed part 42 It is welded in simultaneously as weld part on printed circuit board (PCB), the horizontal level of the bottom surface of the depressed part 42 is less than the insulator foot 10 bottom surface, preferred forms are low 0.05mm in order to which the bottom surface of the depressed part 42 is welded in the printed circuit board (PCB) On.Height of the electric connector of the application in the conducting terminal 40 by compression under in running order is only 1mm, is ensured simultaneously The elastic force of the contact site 45 of conducting terminal 40.

The electric connector of a kind of conducting terminal of the application and the use conducting terminal passes through the base in the conducting terminal 40 Portion 41 corresponds to punching press at the position of abutting part 46 and is recessed to form the depressed part 42 that the confession abutting part 46 slides against, and makes described Abutting part 46 slides against in providing elastic force together with the tightening part for the contact site 45 on the depressed part 42, together When, make the abutting part 46 in the case where being not required to scrape printed circuit board (PCB), make full use of and be recessed under the insulator foot 10 The test space of the depressed part 42 of side, greatly reduces the overall work height of electric connector.
