[embodiment]

Comprise line-end connector (first connector) and the plate terminal adapter (second connector) that connects with it according to electric coupler component 100 of the present utility model, line-end connector comprises insulating body 1 and is fixed on conducting terminal (not shown) in the insulating body 1, and the plate terminal adapter comprises insulating body 6 and is fixed on conducting terminal 7 in the insulating body 6.

Fig. 1 and Fig. 2 have showed the insulating body 1 of line-end connector from different directions.Insulating body 1 is integrally formed by insulating material, is provided with base portion 2 and extends forward to insert the Plug Division 3 in the plate terminal adapter from base portion 2.Base portion 2 is provided with relative front end face 21 and rear end face 22 and some terminal holes 23 that runs through front end face 21, rear end face 22 and be isolated from each other, terminal hole 23 runs through front end face 21 and continues to extend to form forward some terminal pipes 24 that are isolated from each other, these terminal pipes 24 have formed Plug Division 3 jointly, and the sectional area that makes Plug Division 3 is less than base portion 2, thereby makes to have bigger space 34 between Plug Division 3 and the lock catch arm 4.Terminal hole 23 has been formed the conducting terminal passage of accommodating conducting terminal jointly with terminal pipe 24.

The end face of base portion 2 is provided with and is used to keep insulating body 1 and plate terminal adapter connection status, rotatable realizing the lock catch arm 4 of snap close and release, the top that lock catch arm 4 extends to Plug Division 3 with butt connector buckle mutually.Lock catch arm 4 is provided with and links to each other with the end face of insulating body 1 roof and upwardly extending root 43, extend forward in order to contact with butt connector and the latch part 41 of snap close from root 43, and reaching extends back from root uses the press section 42 of rotating lock catch arm 4 for operator presses.Forming gap 25 between the roof of press section 42 and base portion 2 rotates for press section 42.Press section 42 is higher than latch part 41 on vertical direction (referring to simultaneously perpendicular to that direction of docking direction and longitudinally), the person pushes with handled easily.

Fig. 3 is the view after insulating body 1 is decided what is right and what is wrong along center line.Latch part 41 inside are provided with groove 410, thereby the hook portion 411 and the side walls 412 of front end have been formed, hook portion 411 front ends are provided with inclined-plane 4110 and slip into groove 410 with the catch member (being snap close piece 61 in the present embodiment) of guide plate terminal adapter, thereby realize the snap close with the plate terminal adapter.Sidewall 412 can limit snap close piece 61 the rocking on left and right directions that is contained in after snap close is finished in the groove 410.

Fig. 4 has shown that line-end connector and plate terminal adapter connect the view of deciding what is right and what is wrong after finishing.The snap close piece 61 integrally formed with insulating body 6 is housed in the groove 410 of latch part 41, and the stopping surface 611 of snap close piece 61 rear ends is inconsistent with the hook portion 411 of latch part 41, thus being connected between retention wire terminal adapter and the plate terminal adapter.Thereby snap close piece 61 front ends are formed with inclined-plane 612 realizes snap close with the groove 410 that guiding snap close piece 61 slips into latch part 41.Yet, because hook portion 411 and sidewall 412 all still have one section bigger distance apart from the upper surface of plate terminal adapter, when snap close is good hook portion 411 met with outside downward bump or pushes, the end in hook portion 411 the place aheads can rotate around snap close piece 61, thereby made hook portion 411 fractures or damaged.

Fig. 5 has showed that line-end connector and plate terminal adapter connect the three-dimensional view after finishing.After snap close piece 61 stopping surfaces 611 and hook portion 411 snap closes were complete, the projection 44 of latch part 41 both sides can be near the upper surface of plate terminal adapter insulating body 6.Hook portion 411 meets with outside downward bump or when pushing, projection 44 moves down the upper surface that will be resisted against plate terminal adapter insulating body 6 slightly, further rotates to prevent hook portion 411, thereby can protect lock catch arm 4.Moreover, because projection 44 is exposed to the outside, so whether fully the user can determine hook portion 411 and snap close piece 61 snap close by the position of observing projection 44 relative plate terminal adapters.Thereby, can avoid the user to continue to push hook portion 411 and guarantee hook portion 411 and snap close piece 61 complete snap closes.

Certainly, among other embodiment, projection 44 can be set to compress the form of the upper surface of insulating body 6, and hook portion 411 is more stable when meeting with outside downward bump or pushing like this.Its shortcoming is: it is higher to the requirement meeting of manufacturing process, because the projection 44 that big slightly manufacturing tolerance is produced may abut to the upper surface of insulating body 6 before hook portion 411 and snap close piece 61 snap closes, thereby stop the further snap close between hook portion 411 and the snap close piece 61.
