Description
Technical field
The present invention relates to a kind of Seal of Cables joint, especially relate to a kind of seal nipple of armoured cable.
Background technology
The cable of luminaire for marine use or other shipborne equipments is introduced the position higher sealing protection requirement, at present armoured cable joints that adopt are realized connecting and sealing more, in the version of the existing armoured cable joint that is adopted, a kind of is that seal is directly pasted on the armour of armoured cable, armour is the sleeve pipe that is made of metal, because the surface is comparatively coarse, and it is penetrating mutually, can't seal fully, its degree of protection is very low, and the seal nipple of this structure can not really play the waterproof sealing effect.Another seal nipple is to adopt a plurality of parts, a plurality of seal to be spirally connected spiral-lock mutually together, though can play waterproof action, its complex structure, manufacturing cost is higher, and assembling is also cumbersome in addition.
Summary of the invention
The technical problem to be solved in the present invention is, at the above-mentioned defective of prior art, provide a kind of good sealing effect, simple in structure, cost is low and have the seal nipple of the armoured cable of higher degree of protection.
The technical solution adopted for the present invention to solve the technical problems is: a kind of seal nipple of armoured cable, comprise and be sleeved on the clamping element that armoured cable is used to clamp the armour end of armoured cable outward, on the cable sheath in the outside, armour end, be set with seal, clamping element and seal are set with connector outward, and connector locks clamping element and seal on armoured cable.
In the seal nipple of armoured cable of the present invention, described clamping element comprises mutual sheathing clamping bull together and clamps parent part, the armour end of armoured cable is folded to and clamps between bull and the clamping parent part, clamps bull and clamp after parent part cooperates suit the armour end clips to be fastened.
In the seal nipple of armoured cable of the present invention, described clamping bull comprises conical inserting, the inner wall shape that clamps parent part is a cylindricality, the conical inserting cooperation that clamps bull is inserted into and clamps in the parent part, to clamp in the armour end that clamps the armoured cable between bull and the clamping parent part, the conical inserting outer wall is provided with at least one circle groove.
In the seal nipple of armoured cable of the present invention, described clamping bull also comprises fixed part, and described fixed part diameter forms step greater than the conical inserting diameter between the two, after clamping bull and clamping the parent part assembling, clamp parent part end face roof pressure on step.
In the seal nipple of armoured cable of the present invention, described connector comprises and connects bull and be connected parent part, connect bull and removably connect with being connected parent part, the connection bull be connected parent part inside and be provided with and hold the also cavity of fastening fixture and seal.
Seal nipple at armoured cable of the present invention, connect bull and the length that is connected the internal cavities that parent part assembling back forms be slightly smaller than clamping element length and seal drift and, the connection bull and be connected the parent part connection after with the gap between seal crimp hermetically-sealed cable crust and the connector inwall.
At the seal nipple of armoured cable of the present invention, described connection bull be connected parent part and be threaded.
In the seal nipple of armoured cable of the present invention, described seal is the column sealing ring, and the column ring set is on the armoured cable crust, with armoured cable crust matched in clearance.
In the seal nipple of armoured cable of the present invention, described column sealing ring outer wall is provided with squeezing groove, and when the column sealing ring was squeezed, the squeezing groove bottom squeeze was out of shape the clearance seal between cable sheath and the connector inwall.
In the seal nipple of armoured cable of the present invention, described squeezing groove radially is provided with a circle along the column sealing ring, and the degree of depth of squeezing groove is greater than the wall thickness of 1/2 column sealing ring.
The present invention adopts and is sleeved on the armour end that the outer clamping element of armoured cable clamps armoured cable, and adopt direct suit and the seal that pastes on the bright and clean cable sheath comes butt joint to seal, sealing effectiveness is good, realized the waterproof purpose of the seal nipple of armoured cable, in order to prevent the mobile disengaging of clamping element and seal, outside clamping element and seal, be set with connector, connector locks clamping element and seal on armoured cable, has strengthened the reliability of the fail safe and the use of seal nipple.That the present invention has is simple in structure, cost is low, configuration is easy to characteristics.
Be installed in after the present invention turns down the armour end between the clamping bull and clamping parent part of suit, clamp bull and be set with bigger contact area with the clamping parent part, the clamping dynamics is bigger, has higher clamping reliability.In order to strengthen the reliability of clamping, be provided with at least one circle groove at the conical inserting outer wall, make the conical inserting outer wall coarse, be difficult for sliding.And clamping the bull front portion is conical inserting, and the inner wall shape that clamps parent part is a cylindricality, and conical inserting had both guaranteed the convenience of inserting, and made assembling simpler, armour progressively can be clamped when realizing assembling again, reached the purpose of clamping.In order to prevent that conical inserting from excessively injecting clamping parent part, cause and clamp the parent part damage, be provided with fixed part at the rear portion that clamps bull, fixed part is different with the conical inserting external diameter, form step, the conical inserting plug-in mounting put in place be roof pressure to step, just avoid conical inserting excessively to inject to clamping the infringement that parent part causes.
The selected seal of the present invention is the column sealing ring, and the column ring set with armoured cable crust matched in clearance, is convenient to the column ring set on cable sheath on the armoured cable crust.For with the clearance seal between cable sheath and the connector inwall, be provided with squeezing groove at column sealing ring outer wall, when the column sealing ring was subjected to push from direction of both ends, the distortion of squeezing groove bottom squeeze was outwards outstanding, and this outside ledge is with the clearance seal between cable sheath and the connector inwall.In order to reach the purpose of reliable distortion, the degree of depth of squeezing groove is greater than the wall thickness of 1/2 column sealing ring, squeezing groove bottom wall thickness is less like this, distortion easily is squeezed, and squeezing groove is an openings at one side, and being squeezed at first is that opening part shrinks the narrowed width of squeezing groove, the squeezing groove bottom can only outwards be given prominence to, and comes closing gap.
Connector adopts is the connection bull that removably connects and be connected parent part, connect bull and be connected parent part inside and be provided with and hold the also cavity of fastening fixture and seal, the length of this cavity be slightly smaller than clamping element length and seal drift and, with seal crimp, realize the purpose in gap between hermetically-sealed cable crust and the connector inwall after connecting bull and being connected the parent part connection.Employing removably connects and convenient clamping element and seal is assemblied on the cable again with the two locking, and assembling rationally, and is easy to operate.
