Description
Technical Field
The utility model relates to a cable joint mounting structure, concretely relates to plug-in cable joint's locking structure that takes off.
Background
In the plug structure of the 10-35kV 200-plus 400A cable, the tail part of the cable head is closed, so that the terminal of the cable cannot form a balanced support with the insulating plug through the connecting stud to form a suspended wall structure. The installation is influenced by the following points: 1. silicone grease lubrication causes a decrease in friction; 2. the cable joint is a rubber elastic body; 3. the cable itself may slide off of the cable and terminal when installed in place due to its own weight.
In addition, space is not reserved in the domestic and international conditions by considering the elastic deformation of the cable plug head when the terminal which is well crimped by the cable is installed and sleeved in the plug head. All of the above factors affect the installation process and quality.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a plug-in cable joint's locking structure that takes off of cable joint and the aversion slippage phenomenon of power cable in the installation reasonable in structural design, effectual solution.
In order to solve the technical problem, the utility model discloses a binding post and cable joint, cable joint is the rubber material, cable joint includes an inner chamber, the inner chamber includes cooperation portion, bayonet portion and the installation reservation portion of supreme setting down, and binding post cooperatees with the inner chamber, passes the bayonet portion in binding post's upper end, is equipped with the bayonet portion in binding post's upper end and the side of passing the bayonet portion, there is the space between binding post's top and the top of installation reservation portion.
As a further improvement, the utility model is provided with a first annular bulge on the inner wall of the inner cavity, the first bulge forms the bayonet part, the second bulge of the upper end left and right sides face of the clamping part for establishing at binding post, the diameter of the bayonet socket of the bayonet part is less than the diameter of the upper end of binding post.
As a further improvement of the utility model, a guiding part with a shape of a cone frustum is arranged between the first protruding part and the matching part, wherein the small end of the guiding part is positioned above.
As a further improvement of the present invention, the cross-sectional shape of the second protruding portion is a semicircular shape, and a groove matched with the second protruding portion is formed between the first protruding portion and the installation reserving portion.
The utility model has the advantages that: on at first crimping power cable's conductor with binding post, become a linear whole with power cable, be scribbled insulating grease in cable joint's the inner chamber, then enter into cable joint's inner chamber with binding post, the card portion of putting and the fore shaft portion interact, effectively fixed cable joint prevents the aversion, installs the reservation portion simultaneously and can provide fine predeformation space for the on-the-spot installation, laborsaving, swift during the installation, the twist conducting rod that can relax.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a sectional view of the present invention.
Fig. 2 is a structural diagram of the connection terminal of the present invention.
Fig. 3 is a structural diagram of the cable joint of the present invention.
Detailed Description
The cable connector comprises a wiring terminal 1 and a cable connector 2, wherein the cable connector 2 is made of rubber, the cable connector 2 comprises an inner cavity, the inner cavity comprises a matching part 3, a bayonet part 4 and an installation reserved part 5 which are arranged from bottom to top, a circle of annular first bulge part 6 is arranged on the inner wall surface of the inner cavity, the first bulge part 6 forms the bayonet part 4, the wiring terminal 1 is matched with the inner cavity, the upper end of the wiring terminal 1 penetrates through the bayonet part 4, the diameter of a bayonet of the bayonet part 4 is smaller than that of the upper end of the wiring terminal 1, second bulge parts 7 are arranged at the upper end of the wiring terminal 1 and on the left side and the right side of the bayonet part 4, the cross section of each second bulge part 7 is semicircular, a groove 8 matched with the corresponding second bulge part 7 is formed between the first bulge part 6 and the installation reserved part 5, and a guide part 9 in a frustum shape is arranged between the first bulge part 6 and the matching part 3, wherein the small end of the guide part 9 is positioned above, and a gap is arranged between the top of the wiring terminal 1 and the top of the installation reservation part 5.
The utility model has the advantages that: firstly, the wiring terminal 1 is pressed on a conductor of a power cable to form a linear whole with the power cable, insulating lubricating grease is coated in an inner cavity of the cable joint 2, then the wiring terminal 1 enters the inner cavity of the cable joint 2, the clamping part and the clamping opening part 4 interact with each other, the cable joint 2 is effectively fixed to prevent displacement, and smoothness of field installation and reliability of electrical performance are ensured. Meanwhile, the installation reserved part 5 can provide a good pre-deformation space for field installation, and the conductive rod can be easily screwed in a labor-saving and rapid mode during installation.
