Clamping action；And increased and the contact area of inclined plane by arranging of rake, prevent the office being subject on box body and cassette holder
Portion's active force is excessively concentrated, and the phenomenon damaged occurs.
This utility model is further arranged to: be equipped with friction protrusion in two inclined planes.
By using technique scheme, the setting of friction protrusion decreases the contact surface between inclined plane and rake
Long-pending, the active force making inclined plane produce can realize the concentration applying conduction of power by the contact surface between inclined plane and rake,
Make inclined plane rake can be applied bigger active force, it is achieved preferably to clamp between box body and cassette holder, reach the closeest
Envelope effect；And the frictional force that friction protrusion surface exists can reduce the slip produced between inclined plane and rake, will not change
The applying direction of power, makes active force preferably to act on rake.
This utility model is further arranged to: described cassette holder end face is provided with the annular groove caved inward, the end of described box body
Face is provided with and is embedded the ring body into annular groove.
By using technique scheme, increase connecing between box body and cassette holder further by annular groove and arranging of ring body
Contacting surface is amassed, and extends the motion path existed between box body and cassette holder, and making outside enter into the material of tray interior can be by ring body
Stopped, the inside of box body will not be entered directly into, it is achieved better seal effect.
This utility model is further arranged to: is provided with gap bottom described annular groove and between ring body, is provided with in described gap
Thickness is more than the sealing ring of gap width, and the sidewall of described sealing ring stretches out setting towards the periphery of cassette holder.
By using technique scheme, between box body and cassette holder during clamping, sealing ring is applied active force,
And make sealing ring preferably deform upon by the setting in gap and produce bigger elastic-restoring force, make between box body and cassette holder
Realize the effect of interference fit, reach better seal effect.
This utility model is further arranged to: described sealing ring is provided with, towards the one side of box body, the concave face caved inward,
Box body be provided be embedded into concave face and tend to that sealing ring expands outwardly be embedded block.
By using technique scheme, it is embedded block and is embedded in concave face during clamping, be embedded into concave face
The interior block that is embedded increases the volume of sealing ring, makes the deformation tendency that sealing ring expands outwardly；Make sealing ring towards depression
The effect that face preferably applies, reduces the gap existed between sealing ring and concave face further, reaches better seal effect.
This utility model is further arranged to: described box body is provided with the suspension ring for hanging.
By using technique scheme, the mode that box body can be made to lift that arranges of suspension ring realizes fixing, and increases further
Add the scope of application of box body, promote box body practicality in actual use.
In sum, this utility model has the advantages that the setting of anchor ear top incline, makes anchor ear shrink card
Sealing between box body and cassette holder can be promoted to applying the active force of clamping between box body and cassette holder during Jin；By rubbing
Wiping the protruding contact area arranged between minimizing inclined plane and rake, the carrying out making active force more to concentrate is conducted, right
Better seal active force is applied between box body and cassette holder；By sealing ring and the setting being embedded block, increase sealing ring further
Deformation degree, make between box body and cassette holder, to realize more preferable interference fit effect, reach better seal effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of single-ended cable splice closure, including box body 1, cassette holder 2 and clamping box body 1 and box
Anchor ear 3 between seat 2, box body 1 is provided with the suspension ring 8 for hanging, and the end face of cassette holder 2 is provided with the annular groove 9 caved inward, box body
The end face of 1 is provided with and is embedded the ring body 10 into annular groove 9, is provided with gap 11 between bottom and the ring body 10 of annular groove 9；Set in gap 11
Have thickness to be more than the sealing ring 12 of gap 11 width and the sidewall of sealing ring 12 to stretch out setting towards the periphery of cassette holder 2；Close
Seal 12 has caved inward concave face 13 towards the one side of box body 1, and box body 1 is provided with and is embedded into concave face 13 and tends to sealing ring
12 expand outwardly be embedded block 14；Anchor ear 3 is provided with the draw-in groove 4 being embedded for box body 1 with cassette holder 2, and the two side of draw-in groove 4 is the most symmetrical
Being provided with bottom draw-in groove 4 and outward-dipping inclined plane 5, on box body 1 and cassette holder 2, the side towards inclined plane 5 is provided with adaptation
Rake 6 in inclined plane 5；Two inclined planes 5 are provided with equal friction protrusion 7.
With reference to Fig. 1, Fig. 2 and Fig. 3, by be embedded on box body 1 the one of block 14 place facing to concave face 13 on cassette holder 2 position
Put the conflict realized between box body 1 and cassette holder 2 to cover, and make ring body 10 be embedded inside annular groove 9；Draw-in groove 4 on anchor ear 3 is blocked
It is connected on box body 1 and cassette holder 2, by the way of bolt is tightened, shortens the diameter of anchor ear 3, make anchor ear 3 towards box body 1 and box
Move at the axle center of seat 2 and make inclined plane 5 conflict on rake 6, changing anchor ear 3 by the angle of inclination of inclined plane 5 and act on
Impact direction on box body 1 with cassette holder 2, makes rake 6 slide along the incline direction of inclined plane 5, to box body 1 and cassette holder 2 it
Between apply clamping effect；The active force that inclined plane 5 applies carries out power by the contact surface between friction protrusion 7 and rake 6
Conduction, friction protrusion 7 reduces the contact area between rake 6, makes what active force more concentrated to be transmitted to rake 6
On, make rake 6 be subject to the active force more greatly it applied, thus reach better seal effect；Box body 1 and cassette holder 2 are at folder
During Jin, it be embedded and add the volume of sealing ring 12 into the block 14 that is embedded in concave face 13, make sealing ring 12 expand outwardly,
Reduce the effect of the existence lift-off seal in gap 11；Box body 1 applies clamping to sealing ring 12 with cassette holder 2 during clamping
Power, it is achieved the effect of interference fit, reaches better seal effect.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but
As long as all being protected by Patent Law in right of the present utility model.
