Description
Technical field
The utility model belongs to card edge connector structure field, particularly a kind of bending-type structural termination for bayonet connector.
Background technology
Bayonet connector is that a class can for be welded on a female circuit board and can to realize the electric connector of son, female circuit board conducting for a sub-circuit board grafting.In prior art, bayonet connector generally comprises the insulating body that is horizontal elongate body shape, contain in insulating body some on arrange terminal and some lower row's terminals, being fixed with in the left and right sides of insulating body can for the earclip of stator circuit board, on, one end of lower row's terminal has elastic contact part and the other end has leg, on, the leg of lower row's terminal to be positioned at outside insulating body and can for being welded in female circuit board, on, the elastic contact part of lower row's terminal is positioned at the card slot of insulating body and has upper and lower mobility, on, the elastic contact part of lower row's terminal can supply resilient clamp sub-circuit board.
Traditional upper and lower row's terminal structure is generally stamping-out type terminal structure, this terminal structure has the low advantage of Design and manufacture difficulty, but this kind of stamping-out type terminal structure has the large shortcoming of material usage, and the strength of the elastic contact part of its terminal is less, easily cause contact functional bad.Given this, dealer have developed bending-type terminal structure, bending-type terminal structure is formed by Bending Processing by linear pattern material, as Chinese patent 201020257968.X discloses a kind of bayonet connector, and specifically disclose on it and arrange terminal structure, as depicted in figs. 1 and 2, it is arranged conducting terminal 2 by inverted L-shaped connecting portion 24, circular arc convex-shaped elastic arm 25, the contact site 21 of described upper row's conducting terminal, the leg 22 of described abutting part 23 and described upper row's conducting terminal is formed, described abutting part by described upper row's conducting terminal contact site upwards one extend form, described circular arc convex-shaped elastic arm is integrally connected to the rear end of the contact site of described upper row's conducting terminal, the leg of described upper row's conducting terminal is positioned at described insulating body 1 below below, described inverted L-shaped connecting portion connects the leg of described circular arc convex-shaped elastic arm and described upper row's conducting terminal.As shown in Figure 3, after sub-circuit board 4 inserts the inserting groove of the bayonet connector of this utility model, the contact site of upper and lower row's conducting terminal electrically clamps the electrically conducting contact of sub-circuit board, and upper row's conducting terminal 2 abuts to the roof of described upper terminal slot 11, the contact site which increasing upper and lower row's conducting terminal compresses power to the electrically conducting contact of sub-circuit board.But, although this bending-type terminal structure adds the strength of the electrically conducting contact of terminal than traditional stamping-out type terminal structure, but as shown in Figure 3, distance between the fulcrum 2A of its terminal and contact site 21 is longer, be unfavorable for miniaturized bayonet connector overall structure, and present the structure cause of upwards bending due to terminal entirety, the opening 111 of its terminal groove 11 is caused to be positioned at the top of fulcrum 2A, after sub-circuit board 4 inserts, its fulcrum 2A easily upwards departs from, thus affects the stability of terminal.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of bayonet connector terminal structure, this bayonet connector terminal structure can bear larger stress than conventional terminal structure, thus the positive force that the contact site of terminal is larger is provided, to guarantee that terminal contact portion to contact the stability of conducting with sub-circuit board, and be beneficial to bayonet connector integral miniaturization.
The utility model in order to the technical scheme solving its technical problem and adopt is:
A kind of bayonet connector terminal structure, comprise one can for be immobilizated in insulating body holding parts, one from holding parts to extend to insulating body outside form and the cantilever and that can extend from holding parts for the leg, being welded in female circuit board be positioned at cantilevered distal end and can for the contact site of sub-circuit board Elastic Contact, described holding parts is in horizontal and straight type shape, described cantilever tortuous and be after described holding parts bends extension downwards more forward tortuous extension form, the position of the contact of described contact site is lower than the position of the fulcrum of described cantilever.
The utility model in order to the further technical scheme solving its technical problem and adopt is:
Say further, described cantilever be after the front end of described holding parts bends extension downwards more forward tortuous extension form.
Say further, described leg extands rearward to the outside backward downward-extension of insulating body from the rear end of described holding parts for being soldered to female circuit board.
Say further, described terminal is bending-type terminal structure.
Say further, described terminal is upper row's terminal, and described holding parts is close to insulating body top.
The beneficial effects of the utility model are: bayonet connector terminal structure of the present utility model has the cantilever design of meander-like, and cantilever be after holding parts bends extension downwards more forward tortuous extension form, can in the fulcrum of the terminal air line distance limited to this section, contact, increase the space length of cantilever material as much as possible, cantilever is enable to bear larger stress, to provide contact site larger positive force, thus ensure that contact site contacts the stable of conduction property with sub-circuit board; Meanwhile, guaranteeing that cantilever meets with stresses enough greatly, when namely contact site positive force is enough, the air line distance of fulcrum to contact of terminal can be shortened, under guarantee contact site contacts the stable prerequisite of conduction property with sub-circuit board, be beneficial to bayonet connector integral miniaturization; Moreover, because cantilever is lower than holding parts, and the contact of contact site is lower than the fulcrum of cantilever, the opening of the terminal groove of insulating body is caused to be positioned at the below of the holding parts of terminal, holding parts is close to the top of insulating body, active force when sub-circuit board inserts or for terminal after inserting is upwards, and the stressed of terminal can be offset by the top of insulating body, ensure that the stability of terminal fixing and structure.
