The V-shaped structure 5 can reduce the friction force of threading, so that the lead installation efficiency is high. Simultaneously V-arrangement structure 5 can make interference fit deepen, improves the water-proof effects of wire and waterproof end 2, and simple structure is convenient for promote the use.
Example two
This embodiment is based on the further improvement that embodiment one made, and as shown in the accompanying fig. 1-3, the utility model provides a waterproof plug for insert the wire, include: a housing 1; the waterproof end 2 extends into the wiring end of the shell 1, and a through hole 9 for inserting the lead is further formed in the waterproof end 2; waterproof construction 3 sets up waterproof end 2 is last, wherein, waterproof construction 3 is including setting up a plurality of waterproof circles 4 on the 2 inner circles of waterproof end, a plurality of waterproof circles 4 with wire periphery interference fit sets up in order to realize sealed.
In this embodiment, as shown in fig. 1 to 3, the waterproof structure 3 further includes: and a plurality of grooves 6 for bending resistance are arranged on the outer ring of the waterproof end 2, and the grooves 6 are matched with the lead in a bending way. By means of a plurality of peripheral grooves 6 on the watertight end 2. The purpose of doing so is that when the wire is stressed to bend, the groove can be completely bent along with the bending of the wire, so that the overall deformation is reduced; and if the structure of lacking the groove is used when the lead is bent, the waterproof deepened end is slightly bent along with the bending of the lead, and the whole deformation is larger at the moment, so that water is easy to enter.
In this embodiment, and as shown in fig. 1-3, the plurality of grooves 6 includes: the setting is in arc recess 7 of 2 outer lane upper ends of waterproof end and setting are in a plurality of V-arrangement recesses 8 of 2 peripheries of waterproof end, wherein, a plurality of V-arrangement recesses 8 with a plurality of waterproof circle 4 correspond the setting. Because arc recess 7 sets up waterproof end 2 upper ends, waterproof end 2 upper ends and the setting of casing 1 contact, arc recess 7 can effectively be crooked along with the wire is crooked when inserting the wire, reduces whole deformation. And if the structure of lacking the groove is used when the lead is bent, the waterproof deepened end is slightly bent along with the bending of the lead, and the whole deformation is larger at the moment, so that water is easy to enter. Through a plurality of V-arrangement recess 8 correspond with a plurality of waterproof circle 4 and effectively reduce the wire crooked and influence overall structure, avoid taking place the clearance between waterproof end 2 and the wire and intake easily.
In this embodiment, as shown in fig. 1-3, the number of V-shaped grooves 8 is 3. Because waterproof end 2 outer lane upper end and casing 1 fixed connection for upper end hookup location strengthens waterproof end 2 intensity through arc structure. And V-arrangement recess 8 is crooked for the atress position that corresponds with waterproof circle 4, and the purpose of doing so is when the wire atress is crooked, and V-arrangement recess 8 department can be along with the bending of wire and completely crooked, reduces whole deformation, increases whole intensity.
EXAMPLE III
This embodiment is based on the further improvement that embodiment one made, and as shown in the accompanying fig. 1-3, the utility model provides a waterproof plug for insert the wire, include: a housing 1; the waterproof end 2 extends into the wiring end of the shell 1, and a through hole 9 for inserting the lead is further formed in the waterproof end 2; waterproof construction 3 sets up waterproof end 2 is last, wherein, waterproof construction 3 is including setting up a plurality of waterproof circles 4 on the 2 inner circles of waterproof end, a plurality of waterproof circles 4 be used for with wire periphery interference fit sets up in order to realize sealed.
The housing 1 comprises a first housing 11 and a second housing 12 corresponding to the first housing 11, wherein the first housing 11 and the second housing 12 are detachably and fixedly arranged. The first housing 11 and the second housing 12 are fixedly connected through screws, or the first housing 11 and the second housing 12 are connected through a snap.
