Detailed Description
The double-layer protection sealing locking charging pile connector is further described with reference to fig. 1 to 2.
The utility model provides a sealed locking of double-deck protection fills electric pile and connects, characterized by: comprises a joint main body 1, an inner core sheath 3, a screw cap 4 and a double locking cap clamp 2.
The connector body 1 is of a tubular structure, an outer step 11 is arranged on the wall of the outer pipe, the two ends of the connector body 1 are respectively a first end and a second end, and the connector body 1 is provided with external threads on the outer side wall corresponding to the first end and the second end. The nut 4 is in threaded fit with the external thread at the first end of the joint body 1, and a clamping groove 42 which is engaged with the central hole of the joint body 1 is formed between the nut 4 and the joint body 1; the core sheath 3 has a connection section 32, the connection section 32 is fitted in the clamping groove 42 and is deformed by the clamping force of the clamping groove 42 to clamp the cable; the double locking cap clip 2 is attached to the second end of the joint body 1 and includes a locking member to fix the joint body 1 to the cabinet and a cable locking assembly 22 to lock the cable.
Specifically, the nut 4 has an internal thread which is matched with the joint body 1 on the inner wall facing the joint body 1, an inner limiting wall 41 which protrudes from the inner wall of the joint body 1 is arranged on the inner wall of one end back to the joint body 1, and the clamping groove 42 is formed by combining the inner limiting wall 41 and the end wall of the first end of the joint body 1. By rotating the nut 4, the width of the clamping groove 42 can be adjusted by the screw-fitting force, thereby adjusting the degree of deformation of the connecting section 32 to effectively clamp the cable. That is, in this process, the clamping force to the cable can be adjusted according to actual needs.
The inner core sheath 3 further has an extension section 31 formed integrally, the extension section 31 is located at one end of the connecting section 32, which faces away from the joint main body 1, and extends to the outside of the nut 4, and the outer diameter of the extension section 31 is smaller than the outer diameter of the connecting section 32, so as to form a step between the connecting section 32 and the extension section 31, against which the inner limiting wall 41 abuts and presses, and the diameter, i.e., the inner diameter and the outer diameter, of the extension section 31 gradually decrease from one end of the corresponding connecting section 32 to one end of the connecting section 32, which faces away from the connecting section 32. The inner diameter of the extension section 31 is gradually reduced, so that the cable can be effectively wrapped, the sealing length of the cable can be prolonged, and the waterproof and dustproof effects between the inner core sheath 3 and the cable can be further improved; the gradual reduction of the outer diameter not only reduces the consumables, but also facilitates the extension section 31 to pass through the nut 4 so that the connection section 32 is installed in the nut 4.
On the outer side wall of the extension section 31, there is a reinforcing rib 311 coaxial with the core sheath 3 to improve the strength of cable wrapping and stability.
An annular groove 321 which is coaxial with the joint main body and facilitates the deformation of the connecting section 32 is arranged on the outer side wall of the connecting section 32, and when the two ends of the connecting section 32 are pressed and stressed, the central part of the annular groove can be radially inwards deformed so as to effectively clamp the cable.
The locking member is a locking nut 21, and the locking nut 21 is screw-fitted on the second end of the joint body 1 and forms a mounting groove 12 with the outer step 11. When the connector is installed, the second end of the connector body 1 is installed into the installation hole of the cabinet, the outer step 11 is abutted against the outer wall of the cabinet, and then the locking nut 21 is screwed on the inner side of the cabinet, namely the second end of the connector body 1, so that the locking nut 21 is tightly attached to the inner wall of the cabinet, and the connector is fixed on the cabinet.
In order to further improve the sealing between the present invention and the cabinet, a sealing ring 13 is provided in the mounting groove 12.
The cable locking assembly 22 includes a positioning plate 221, an adjusting bolt 222, and a half ring 223. The positioning plate 221 has two blocks and is integrally formed on the end wall of the lock nut 21 facing away from the outer step 11; the two positioning plates 221 form a symmetrical structure with the central axis of the joint main body 1 as the center, and may also be asymmetrical in use. The two half rings 223 are symmetrically disposed on both sides of the two alignment plates 221 and fixed to the alignment plates 221 by the adjustment bolts 222, while a locking ring coaxial with the connector body 1 and capable of clamping a cable is formed outside the second end of the connector body 1.
Connecting holes for matching the adjusting bolts 222 are formed in the end walls of the half rings 223 and the positioning plate 221, and an internal thread is formed in the connecting hole of one of the half rings 223. During the use, the pilot pin wears to establish simultaneously in the connecting hole of two semi-rings 223 and the connecting hole of locating plate 221, rotates behind the adjusting bolt 222, can press from both sides tightly or loosen two semi-rings 223, plays the effect of elasticity to the cable.
In this embodiment, the connector main body 1 and the nut 4 are made of aviation aluminum, that is, the aviation aluminum connector main body 1 and the aviation aluminum nut 4, and the inner core sheath 3 and the seal ring 13 are made of silicon rubber, that is, the silicon rubber inner core sheath 3 and the silicon rubber seal ring 13. On the basis of realizing clamping and sealing, the material also has the characteristic of light weight so as to improve the cost performance.
When the cable clamp is used in cooperation with a cable, the clamping force of the connecting section 32 of the inner core sheath 3 on the cable can be adjusted through rotating the nut 4, and the clamping force on the cable can also be adjusted through rotating the adjusting bolt 222, so that the cable can be effectively clamped and sealed, the sealing and anti-loosening effects are improved, and the cable clamp has the advantages of being high in use flexibility and convenient to use.
