Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is done to further concrete detailed explanation.
As Fig. 2, Fig. 3, shown in Fig. 5 and Fig. 6, a kind of electric coupler component of small size band auto-lock function, comprise plug 2, socket 1 be arranged in plug 2 for being connected the contact 12 of wire, described plug 2 is provided with a header body 5 for gang socket 1, header body 5 outer cover are provided with one can be along the axially movable plug body 4 of header body 5, the outer peripheral face of described header body 5 be provided with can be under pressure along the plug bullet pawl 6 of header body 5 radial deflections, the outer peripheral face of plug body 4 is provided with and can supplies the radially-protruding shell draw-in groove 10 of plug bullet pawl 6, the jack inwall of socket 1 is provided with after plug 2 is in place, the locking draw-in groove 8 matching with plug bullet pawl 6.
This detailed description of the invention, described plug bullet pawl 6 is to be symmetricly set on two arm-type structures of elastic suspended that axially overhang forward along header body 5 on outer peripheral face, the front end of plug bullet pawl 6 is provided with the bullet pawl boss 7 of extended shell draw-in groove 10. Described plug bullet pawl 6 can be also can be along the resilient key formula structure of header body 5 radial expansions.
Described plug bullet pawl 6 is provided with in the time that plug body 4 moves axially along header body 5, can guide shell draw-in groove 10 lower edges to make the lead-in chamfered of its compressing plug bullet pawl 6 radial deflections, and the lead-in chamfered of this detailed description of the invention is arranged on and plays on pawl boss 7.
On described plug body 4 inwalls, be the position of an angle of 90 degrees with described shell draw-in groove 10, also be provided with in releasing process for limiting the spacing preiection 11 of plug body 4 post-tensioning positions, described spacing preiection 11 is located at the rear of shell draw-in groove 10, be provided with and stop the limited step moving after spacing preiection 11 continues at header body 5 outer peripheral faces, described limited step is located at the rear of spacing preiection 11, and its position should minimumly meet the position that plug body 4 post-tensioning compressing bullet pawl boss 7 depart from completely to it while locking draw-in groove 8.
As shown in Figure 7 and Figure 8, described contact 12 is arranged on 5 li of header body by contact hangnail 13, and the terminals of contact 12 are provided with a U-shaped compressing tablet 14, and the both sides of described U-shaped compressing tablet 14 connect by securing member, to clamp the wire wearing in U-shaped compressing tablet 14.
When wiring, by after wire 16 wire strippings, on request metal wire core segment is inserted in the U-shaped compressing tablet 14 of contact 12, screw 15 is penetrated to installing hole, at the other end of screw 15, screw with sides nut, wire 16 fixedly completes. Figure 9 shows that contact piece structure of the prior art, it is by the access part of wire is put in after a joint sleeve 17, directly compressed to be fixed with the end of screw, compared with prior art, use the contact piece structure wiring in the present invention more firm.
When the present invention will install locking, as shown in Fig. 3 and Figure 10, socket 1 is fixed on socket fixing board 19, by in the installing hole of plug socket shell 9, when hearing the sound of " click ", illustrate that playing pawl boss 7 has snapped in 8 li of the locking draw-in grooves that are arranged on jack housing 9 installing hole inwalls, locking process completes. This detailed description of the invention is also provided with accordingly colour code ring 18 on the excircle of plug body 4, as shown in figure 10, when colour code ring 18 is just all covered by plug fixed head 20, illustrates that plug 2 and socket 3 have completed locking.
When release as shown in Figure 4, firmly pull backward plug body 4, header body 5 retainer shafts are to static, playing pawl boss 7 radial contraction under the compressing of shell draw-in groove 10 lower edges moves, until it departs from locking draw-in groove 8 and shell draw-in groove 10 completely, plug body 4 now also stops under the effect of spacing preiection 11 and limited step, and releasing process finishes.
