Detailed Description
In order to further explain the technical means and technical effects of the present invention, the following embodiments are combined to explain the present invention in detail.
As shown in fig. 1, the utility model discloses a stay cord unblock prevents slow-witted connector includes the socket and the plug of inserting to socket, 1 both sides of plug housing are provided with first cylinder 2 and second cylinder 3 respectively and are used for respectively making the spanner install on plug housing with the first mating holes 5 and the 6 cooperations of second mating holes of spanner 4 both sides, the internal diameter inequality of first cylinder and second cylinder external diameter inequality and first mating holes and second mating holes makes first mating holes can only with first cylinder adaptation, thereby the second mating holes can only realize preventing slow-witted when spanner and plug housing assembly with the second cylinder adaptation. The central axes of the first cylinder and the second cylinder coincide so that the wrench can rotate around the first cylinder and the second cylinder. The two sides of one end of the wrench are provided with clamping hooks 7 which are matched with locking columns 9 on the two sides of the socket shell 8 to realize locking after the head seat is inserted; the other end of the wrench is provided with a pull rope 10 in a clamping mode or a nut screwing mode, and under the head seat locking state, the wrench can rotate around the first cylinder and the second cylinder by pulling the pull rope, so that the separation unlocking between the clamping hook and the locking column can be realized.
Furthermore, mushroom head protrusions 11 are arranged on two sides of the shell at the other end of the wrench and used for installing the pull rope, and circular holes 12 with teeth at two ends of the pull rope are limited in grooves 13 of the mushroom head protrusions in a clamping mode, so that the pull rope is not prone to loosening from the wrench. The mushroom head bulge 11 and the clamping hook 7 on the wrench are respectively positioned at two ends of the wrench, and the first matching hole and the second matching hole are positioned between the mushroom head bulge and the clamping hook. The assembly mode between the pull rope and the wrench can also be a nut screwing mode, a rope punching mode and the like.
Further, as shown in fig. 1, the top surface of the socket housing is further provided with a slot 14 for cooperating with a rib 15 on the top surface of the plug housing to prevent the head from being fooled during the opposite insertion of the head, when the head is inserted, only one side of the socket housing provided with the slot cooperates with one side of the plug housing provided with the rib to enable the opposite insertion, otherwise, the opposite insertion cannot be performed, so that the head is fooled during the opposite insertion of the head. The plug insertion end is further provided with a radial sealing ring 16 which realizes sealing between the plug insertion end shell and the socket shell after the head bases are oppositely inserted. Meanwhile, the plug shell is also provided with an elastic ring 17 which realizes the sealing between the socket plugging end shell and the plug shell after the head seat is plugged. Specifically, the elastic ring 17 is located behind the rib 15.
Further, the locking end 18 of the locking post may be curved for mating with a hook to facilitate locking of the hook or to facilitate smooth separation of the hook from the locking post during unlocking.
The utility model discloses a other structural feature of waterproof connector plug and socket can be with prior art, for example: the rear end of the receptacle is mounted to the mounting panel by screws 19 (the mounting panel is not shown in fig. 1 and 2), while the rear end of the receptacle is fitted with a receptacle gasket 20 to effect a pre-receptacle-to-mounting panel seal after the receptacle is mounted to the mounting panel. The tail end of the plug is provided with a positioning groove 21 used for being matched with a bulge 23 on the elastic claw 22 to realize positioning and installation of the elastic claw, the plug 24 is assembled in the elastic claw, the tail part of the plug is connected with a plug 25, and after the plug and the elastic claw are assembled in place, the nut 26 is in threaded connection with the tail part of the plug to wrap the elastic claw in the nut. The nut housing is provided with a ring groove 27 for mounting a pull ring 29 at the end of a fall-preventing cord 28 by which the nut is prevented from falling and being lost, the front end of which is fitted over the first or second cylinder and clamped between the wrench and the plug housing. The hanging ring 30 at the front end of the rope connected with the plug is hung on the hook in the plug shell. Fig. 3 shows not the hook but only the hanging ring at the front end of the rope connected to the stopper plug. When the plug is not connected with the cable, the plug is plugged by the plug to realize dust prevention.
The utility model discloses a when waterproof connector headstock is to inserting, thereby earlier make the spanner make the trip rotary displacement leave the space around first cylinder and the rotation of second cylinder and make the headstock to inserting through stay cord pulling spanner, the headstock is to inserting the back that targets in place, makes spanner counter-rotation and thereby the trip card on making the spanner is fixed and is realized the headstock and lock on the locking post of socket shell both sides. When the unlocking is needed, the pull rope is pulled to enable the wrench to rotate, so that the clamping hooks on the wrench are separated from the locking columns on the two sides of the socket shell to achieve unlocking. The locking and unlocking mode needs small space, and the effective unlocking of the wrench can be realized when the installation space of the waterproof connector is narrow. When a plurality of connectors are installed side by side and used, the utility model discloses an unlocking mechanism can realize normal effectual unblock. And the assembly mode of the wrench and the plug shell can only be installed normally and cannot be installed reversely, so that the assembling fool-proofing can be realized.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any person skilled in the art can make any simple modification, equivalent change and modification to the above embodiments according to the technical spirit of the present invention without departing from the scope of the present invention.
