Embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the utility model do, but execution mode of the present utility model is not limited thereto.
Embodiment 1:
As shown in Figure 1, Anti-loose electrical connection module, comprises plug and socket.
Described socket comprises Socket casing 21, nut 22, columned socket insulator 23, and described nut 22 rear end is connected with Socket casing 21 front end, and the two is coaxial; Socket insulator 23 is positioned at Socket casing 21 and nut 22, and this socket insulator 23 is provided with jack 24, and described nut 22 is provided with internal thread.
The plug casing 11 that described plug comprises hollow cylindrical, the contact pin 13 being arranged on the columned pin insulator 12 in plug casing 11 and being plugged on pin insulator 12; Institute's plug casing 11 is outer is also arranged with back-up ring 14, and described back-up ring 14 outer wall front end is provided with snap ring 141, back-up ring 14 outer wall rear end is provided with connecting thread 16, back-up ring 14 outer wall stage casing is smooth and do not arrange any parts.Snap ring 141 and back-up ring 14, plug casing 11 are all coaxial, and snap ring 141 is close to back-up ring 14 outer wall and is arranged.Connecting thread 16 matches with the internal thread of nut 22; Described back-up ring 14 and snap ring 141 can snap in nut 22, and when back-up ring 14 snaps in nut 22, connecting thread 16 is threaded with nut 22; Described back-up ring 14 is made up of with the mode split that recess is relative the baffle plate that two cross sections are curved, and as shown in Figure 1, the center of circle of two baffle plates overlaps and has between two baffle plates between the relative side of gap and baffle plate two and has gap the structure after split.
In the present embodiment, back-up ring 14 front end does not arrange external screw thread and only arranges a snap ring 141, during installation, user only needs back-up ring 14 easily to push nut 22, between adjacent two helixes snap ring 141 being snapped in the rear end of nut 22, nut 22 and socket are rotated one to two circle again, makes back-up ring 14 rear end be connected plug and socket firmly can be fixed with nut 22 nose threads.Compared with traditional screw thread coupling, winding number needed for the electrical connection module of the present embodiment (i.e. the rotation number of turns of nut 22) is few, therefore not only plug and socket stable connection, and installation rate is fast.
Embodiment 2:
On the basis of embodiment 1, also back-up ring 14 is improved as follows in the present embodiment:
Described back-up ring 14 outer wall rear end is also arranged with binding ring 15, it is that binding ring 15 inwall is provided with the internal thread matched with the external screw thread of back-up ring 14 outer wall that described binding ring 15 is threaded in the section of connecting thread 16 place, the length of binding ring 15 is less than connecting thread 16 back-up ring 14 length axially on back-up ring 14, therefore, binding ring 15 can rotate and moving axially along back-up ring 14 on back-up ring 14.The effect of binding ring 15 has 3, and one be fixing back-up ring 14, two is carry out spacing to nut 22, three is make plug and socket stable connection further, when the nut 22 of socket is rotated in place on back-up ring 14, the direction of binding ring 15 to back-up ring 14 front end can be moved, compress back-up ring 14.When the connection of plug and socket is very stable, the position of binding ring 15 can be adjusted.
