Abstract
The invention discloses a connection accessory capable of preventing breakage of cables, which comprises a connection casing, a closed rubber pipe, a press ring, a spring nut and a spring. The connection casing is provided with inner threads and outer threads, an inner hole is provided with a step, the spring nut is provided with a spring seat connected with the inner threads, and the spring is divided into a large-diameter section and a large-thread-pitch section. The closed rubber pipe and the press ring are inserted into the connection casing, the spring penetrates through the spring nut, and the spring nut together with the spring meshes with the outer threads on the connection casing. By the aid of the connection casing and the spring, stress concentration of root joints of the cables and electric connectors is alleviated effectively, original strength of the cables is maintained, the service lives of dynamic cables are prolonged, and work reliability of mobile electric equipment is guaranteed. Besides, the connection accessory is simple in structure and convenient in mounting and demounting.
Description
Technical field
The present invention relates to technical field of electric connectors, especially a kind of coupling that prevents that cable from losing.
Background technology
Practical applications in; The cable that is connected with electric equipment through electric connector is divided into two kinds of situation; A kind of is the cable that is connected with fixed electric equipment, is commonly referred to static cable, and another kind is the cable that is connected with the electric equipment that moves; Be commonly referred to dynamic cable, dynamic cable in use inevitably can bend, wear and tear.In the course of work that moves electric equipment, cable need stand bending repeatedly, especially at the be connected root of cable with electric connector; Cause stress to concentrate the most easily owing to connect root; Under the effect of alternate stress, the intensity of cable root is significantly reduced, cause insulating barrier wearing and tearing, core to fracture; Gently then influence the normal production order, heavy then cause production accident.
Summary of the invention
A kind of coupling that prevents that cable from losing that the objective of the invention is to be directed against the deficiency of prior art and provide.The present invention adopts the structure that connects housing and spring; Effectively alleviate cable and be connected the phenomenon that Root Stress is concentrated with electric connector; Protect the due intensity of cable, prolonged the useful life of dynamic cable, guaranteed the functional reliability of mobile electric equipment; And simple in structure, installation, convenient disassembly.
The concrete technical scheme that realizes the object of the invention is:
A kind of coupling that prevents that cable from losing, its characteristics comprise connection housing, caulking gum pipe, trim ring, spring nut and spring, and said connection housing is a cylindrical tube shape; The one of which end is provided with internal thread, the other end is provided with external screw thread; The endoporus that connects housing is provided with step, and said caulking gum pipe is a cylindrical tube shape, is furnished with the convex tendon of ring-type on its inner surface; Trim ring is provided with the annular ring of boss for-end face; Spring nut one end is provided with the connection internal thread, the other end is provided with spring base, spring-to hold to be provided with enlarged diameter section, the middle part is provided with a few coarse pitch sections; Said caulking gum pipe and trim ring insert the step place of endoporus by connecting the housing male end; And the boss of trim ring is hampered by the end face that connects housing; Spring is through in the spring nut, and enlarged diameter section is positioned at the spring base inboard, and spring nut is connected the male end that connects housing together with spring; Internal thread on the spring nut be connected housing on external screw thread engagement, and the spring base on the spring nut presses the boss applying of enlarged diameter section with the trim ring of spring.
The present invention adopts the structure that connects housing and spring; Effectively alleviate cable and be connected the phenomenon that Root Stress is concentrated with electric connector; Protect the due intensity of cable, prolonged the useful life of dynamic cable, guaranteed the functional reliability of mobile electric equipment; And simple in structure, installation, convenient disassembly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a user mode sketch map of the present invention.
Embodiment
Consult Fig. 1, Fig. 2, the present invention includes connection housing 1, caulking gum pipe 2, trim ring 3, spring nut 4 and spring 5, said connection housing 1 is a cylindrical tube shape; The one of which end is provided with internal thread 11, the other end is provided with external screw thread 12; The endoporus that connects housing 1 is provided with step 13, and said caulking gum pipe 2 is a cylindrical tube shape, is furnished with the convex tendon 21 of ring-type on its inner surface; Trim ring 3 is provided with the annular ring of boss 31 for-end face; Spring nut 4 one ends are provided with connection internal thread 41, the other end is provided with spring base 42, spring 5-to hold to be provided with enlarged diameter section 51, the middle part is provided with a few coarse pitch sections 52; Said caulking gum pipe 2 and trim ring 3 are by connecting step 13 places that housing 1 external screw thread 12 ends insert endoporus; And the boss 31 of trim ring 3 is hampered by the end face that connects housing 1; Spring 5 is through in the spring nut 4; And enlarged diameter section 51 is positioned at spring base 42 inboards; Spring nut 4 is connected external screw thread 12 ends that connect housing 1 together with spring 5, the internal thread 11 on the spring nut 4 with is connected housing 1 on external screw thread 12 engagements, and the spring base on the spring nut 4 42 presses boss 31 applyings of the enlarged diameter section 51 and the trim ring 3 of spring 5.
Installation of the present invention:
Application of the present invention:
During application, dynamic cable 6 is connected with mobile electric equipment through the present invention, when mobile electric equipment moves; Drag dynamic cable 6 movement therewith, stung tightly because the connection root of dynamic cable 6 at first connects the convex tendon 21 of ring-type on caulking gum pipe 2 inner surfaces in the housing 1, and then its extending area is supported on again in the spring 5; Because the enlarged diameter section 51 of spring 5 is by spring base 42 relative fixed of spring nut 4, so, the bending stress of dynamic cable 6 in motion process; Can't be directly delivered to the root of caulking gum pipe 2, and supported, and bend thereupon by the coarse pitch section 52 at spring 5 middle parts; Because under the supporting role of spring 5, the bending radius of dynamic cable 6 increases, dynamic cable 6 is connected effective alleviation of phenomenon quilt that Root Stress is concentrated with electric connector; Thereby protected the due intensity of cable, prolonged the useful life of dynamic cable 6, guaranteed the functional reliability of mobile electric equipment; And simple in structure, installation, convenient disassembly.
When the present invention separates, only need spring nut 4 and connect shell 1 back-out to get final product, neither can damage dynamic cable, make execute-in-place simple and convenient again.
