Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model discloses an embodiment of anticreep electric connector subassembly, as shown in fig. 1 to 8, anticreep electric connector subassembly, including plug 1 and socket 2, plug 1 is including having plug housing 11 and rotating the connecting nut 12 that sets up on plug housing 11, socket 2 includes socket housing 21, be equipped with the connecting thread that is used for supplying connecting nut 12 to connect on socket housing 21, socket housing 21 is last to be equipped with anticreep groove 24 in connecting thread's position department, the position department that corresponds anticreep groove 24 on connecting nut 12 is equipped with the mounting groove 123 that runs through its inner and outer wall, install anticreep pin 15 in the mounting groove 123, anticreep pin 15 is in connecting nut 12 inside part cartridge to anticreep groove 24. The connecting nut 12 and the plug housing 11 are connected in a circumferentially rotating and axially blocking fit manner through a corrugated spring 13. Meanwhile, a plug insulator 14 is provided in the plug housing 11, the plug insulator 14 is fixed in the inner cavity of the plug housing 11 by a plug insulator collar 17, and the socket contact 16 is mounted in a mounting hole on the plug insulator. The socket housing 21 has a socket insulator 22 mounted therein by a socket insulator 22, and the pin contacts 23 are directly mounted on the socket insulator 22.

In this embodiment, mounting groove 123 is equipped with two on coupling nut 12 relatively, and anticreep pin 15 is for having two anticreep portions 152 that set up with two mounting grooves 123 one-to-ones and connecting the "door" shape structure at the connecting portion 151 of two anticreeps outer ends, and it is spacing that like this coupling nut 12's both sides can both carry out the anticreep, makes its atress more even, and is stable better.

In order to facilitate the installation of the anti-falling off bar 15 and prevent it from falling off from the installation groove 123, in this embodiment, the anti-falling off bar 15 is an elastic bar, and the two anti-falling off portions 152 are in a contracted state or an expanded state when in a free state, and can be elastically clamped in the two installation grooves 123 after being inserted into the installation groove 123. Specifically, as shown in fig. 8, in the present embodiment, two anti-separation portions 152 are in a contracted state, and an angle between the two anti-separation portions 152 is inconsistent with an angle between the two mounting grooves 123, so that when the anti-separation portions are mounted in the mounting grooves, the two anti-separation portions need to be separated, so as to be inserted into the mounting grooves, and after the mounting is in place, the anti-separation rod 15 is limited in the mounting groove under the action of elastic force, so that other structures do not need to be additionally arranged, and thus the structural complexity is reduced.

In the present embodiment, the receiving groove 122 for receiving the connecting portion 151 is provided on the outer circumference of the coupling nut 12 at a position between the two mounting grooves, so that the mounting portion can be received in the receiving groove 122, avoiding being exposed to the outside excessively to be accidentally detached by an external force.

Considering still need unblock between plug and the socket, the unblock in-process just need pull down the anticreep pin, for the convenience of the dismantlement of anticreep pin, in this embodiment, one side of holding tank 122 is equipped with rather than the intercommunication, is used for supplying the unblock instrument to enter into the guiding groove 121 in order to prize out the anticreep pin in holding tank 122. In the unlocking process, an unlocking tool (a flat screwdriver can be directly adopted) can be inserted into the accommodating groove through the guide groove 121, and the connecting portion 151 is pried out.

In order to ensure that the anti-disengagement lever can be smoothly inserted into the anti-disengagement groove 24, in this embodiment, the anti-disengagement groove 24 is a circular groove disposed around the circumference of the socket housing, so that the anti-disengagement lever can be smoothly inserted into the anti-disengagement groove as long as the mounting groove and the anti-disengagement groove are corresponding in position no matter which angle the connecting nut 12 rotates.

In other embodiments of the present invention, only one mounting groove may be provided, and the anti-falling stop lever is a single rod-shaped structure; the anti-falling stop lever can be also provided with a barb structure, and the barb structure is hooked on the connecting nut; the anti-drop groove can also be in an interrupted groove type structure.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
