Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing 1-5, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only a part of preferred embodiment of the present invention rather than whole embodiments.
Those skilled in the art can do similar deformation in the case of intension of the present invention, and therefore the present invention is not by described below
The restriction of specific embodiment.
The invention provides a kind of cable intermediate joint protecting box (as shown in Figure 1), including the protecting box basis of inner hollow
Body 1, in actual application, cable intermediate joint is positioned at protecting box body 1, and described protecting box body 1 includes protection
Box body 11 and lower protection box body 12, upper protection box body 11 version is as in figure 2 it is shown, upper protection box body 11 and lower protection box body 12
Can be mutually butted together.Protect on described and be provided with through hole on the outward flange of box body 11 and lower protection box body 12
Buttcover plate 1121, protect the two ends, left and right of box body 11 respectively to arrange and fix halfbody 112 on one, in described lower protecting box on described
The two ends, left and right of body 12 respectively arrange and fix halfbody 121, described upper protection box body 11 be positioned at the fixed of its two ends
Halfbody 112 is an overall structure, can pass through casting technique one-shot forming, described lower protection box body 12 be positioned at described in its two ends
The most fixing halfbody 121 is an overall structure, can pass through casting technique one-shot forming, lower fixing halfbody 121 and upper fixing half equally
Body 112 can be docking together, and is provided with winding arc groove on fixed halfbody 112 and described lower fixing halfbody 121,
Winding arc groove 113 in upper fixing halfbody 112 is relative with the winding arc groove in lower fixing halfbody 121, upper fixing halfbody 112
Winding arc groove in interior winding arc groove 113 and lower fixing halfbody 121 is all internal with described protecting box body 1 to connect,
In actual application, the cable at cable connector is pressed on fixing halfbody 112 and lower fixing halfbody 121
In the circular channel of the docked composition of winding arc groove, winding arc groove can effectively decompose the axial tension suffered by cable,
Thus at cable connector, it is to certain protective effect, and winding arc groove 113 two ends is straight end, and pars intermedia is bending,
Further, the axis at the two-port of winding arc groove 113 is parallel to each other, and is all provided with at the internal two ends of described protecting box body 1
Put a stopping means 4.In this specific embodiment, preferably two kinds of detailed description of the invention of stopping means 4, stopping means 4
The first detailed description of the invention is (as shown in Figure 4): described stopping means 4 includes a spring 41 and two pressure strips 42, two
Individual described pressure strip 42 is nested with inside described spring 41, is provided with a limiting plate 421 on institute's pressure strip 42 front end outer side wall,
In application process, pressure strip 42 tightly by plug between cable lateral wall and spring 41, and cable and pressure strip 42 will not
Relative motion occurs, and cable intermediate joint is between two springs 41, and its suffered pulling force is less, is pulled by external force at cable
It is that the cable at cable connector can effectively keep out the pulling force suffered by cable by pressure strip 42 and spring 41, thus can protect
Do not dropped easily at cable connector；For reducing further at cable connector, suffered axial during long-term use
Pulling force, here, be provided with the second specific embodiment of stopping means 4: described stopping means 4 is that a position-limiting tube 43 is (such as Fig. 3 institute
Show), the leading inside wall of described position-limiting tube 43 arranges a groove, described position-limiting tube 43 lateral wall arranges one with described
The guide pipe 45 that groove connects, described guide pipe 45 upper end, with female thread (as shown in Figure 5), arranges one in described groove
Compact heap 44, and the rear end of described compact heap 44 is nested with in described guide pipe 45, also sets up one in described guide pipe 45 upper end
The bolt 46 matched with described female thread, just can be promoted by swivel bolt 46 compact heap 44 to move down, thus can compress
Being positioned at the cable of position-limiting tube 43, the end of position-limiting tube 43 is stuck in protecting box body 1, will not move along the direction that pulls of cable
Dynamic, it is achieved thereby that to the protection at cable connector.
For preventing the cable at the two ends at cable connector from sliding in winding arc groove, here, in upper fixing halfbody 112
Winding arc groove 113 in and lower fixing halfbody 121 in winding arc groove in be provided with anti-skidding salient point 3, for preventing at water
This is internal to be flowed into protecting box, and the outer end of winding arc groove is provided with sealing gasket 2.
At cable connector, there is explosion time, discharging for ease of explosion energy, on described, protect box body 11 and described
It is provided with two on lower protection box body 12 and lets out energy hole 111, let out energy hole 111 interior with rubber closure, to prevent water from dividing from letting out energy hole
Enter in 111 in protecting box body 1.
In the present invention, the relative position that "left", "right" is for conveniently describing position relationship and uses, therefore can not make
It is interpreted as limiting of its scope for absolute position.
In addition to the technical characteristic described in description, it is the known technology of those skilled in the art.
The above combines accompanying drawing and is described above in detail the preferred embodiment of the present invention and embodiment, but the present invention is not
It is confined to the above-described embodiment and examples, for those skilled in the art, without departing from structure of the present invention
On the premise of think of, it is also possible to make some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
