Description

A kind of colliery telecommunication cable assembly

Technical field

The utility model relates to telecommunication cable assembly field, relates in particular to a kind of telecommunication cable assembly that can be used for the colliery.

Background technology

The operational environment in colliery is more abominable; the telecommunication cable assembly that many times uses at usual environment can't be applicable to coal mine environment; the communications cable that coal miner adopts and the connected mode of equipment are: generally be first the colliery of palpus connection device to be peelled off oversheath, peel off insulating barrier, exposed conductor with the telecommunication cable termination; adopt kink conductor or welding conductors that it is connected, again with adhesive tape or heat-shrinkable T bush protection joint.Existing colliery is mainly manifested in following several respects with the shortcoming that telecommunication cable assembly connecting mode and joint protective exist: kink may make conductor damage, heating, insecure, very easily oxidation brittle failure of joint, and the signal transmission is relatively relatively poor; Welding manner easily forms rosin joint, and solder joint is crossed conference and caused that insulation resistance is not up to standard between the solder joint, interference is larger, and reliability is relatively low, and production efficiency is lower, and water proofing property is poor, and fatigue resistance is lower.Adhesive tape or heat-shrinkable T bush protection joint, adhesive tape and heat-shrinkable T bush are very easily aging, and the anti-salt oil preventing performance of waterproof is poor, high-low temperature resistant not, the resistance to wear crushing resistance is all relatively poor, and outward appearance is not attractive in appearance simultaneously, and consistency is relatively poor.

Summary of the invention

In order to address the above problem, the utility model provides a kind of telecommunication cable assembly that can be used for the colliery, comprises plug, crimp type terminal, tail accessory, injection casing.Described injection casing comprises interior injection molded layers and outer injection molded layers; One end of described interior injection molded layers is socketed on the cable of ore deposit, and the other end is socketed on the tail accessory, and described outer injection molded layers is coated on outside the interior injection molded layers.The contact area of tail accessory and interior injection molded layers has an annular groove, is placed with the armouring wire protective layer in the described annular groove.The protective layer used NI-G ring of described armouring wire is pushed down.

Tail accessory and plug are inserted the colloid that embedding is arranged in the outer space of heart yearn.Described outer injection molded layers one end is connected with tail accessory, and the other end is socketed on the cable of ore deposit.

Ore deposit cable conductor and crimp type terminal crimping were packed into after good in the patch bay when the utility model used, and be safe and simple, can transmit simultaneously power supply and signal, do not interfere with each other, and forms seamless reliable connection.Double injection shell waterproof, antidetonation, safe, practical property are strong.

Description of drawings

Fig. 1 is the vertical half section structural representation after the utility model inserts cable;

Among the figure: 1. plug, 2. mounting panel, 3. crimp type terminal, 4. conductor, 5. protuberance, 6. tail accessory, 7. interior injection molded layers, 8. outer injection molded layers, 9. NI-G ring, 10. bayonet socket, 11. armouring wire layers, 12. ore deposit cables, 13. screens, 14. annular grooves.

Embodiment

The utility model is described in further detail below in conjunction with Fig. 1.

Technical solution of the present utility model is: a kind of colliery telecommunication cable assembly mainly comprises: plug 1, crimp type terminal 3, tail accessory 6, injection casing.

Described plug 1 contains mounting panel 2, and crimp type terminal 3 concrete quantity can be decided according to demand.Pass tail accessory 6 after the conductor 4 of wire and crimp type terminal 3 adopts the mode of crimping to be connected in the ore deposit cable 12 during use and place in the mounting panel 2, wherein wire is connected the screen 13 of cable 12.

Injection casing comprises two-layer: interior injection molded layers 7 and outer injection molded layers 8.One section of interior injection molded layers 7 is socketed on the ore deposit cable 12, another section is socketed on the right-hand member described in tail accessory 6 figure, be used for being connected and fixed plug 1, ore deposit cable 12, armouring wire layer 11, reach the purpose of resistance to compression, tension, heatproof, wear-resisting, water-tight, reinforcement bonding strength; Outer injection molded layers 8 is coated on outside the interior injection molded layers 7 fully, and one section is connected with tail accessory 6, and another section is socketed on the ore deposit cable 12.The structure of injection casing has guaranteed the highly reliable use of mining cable assembly in complex environment, and outward appearance is also elegant in appearance simultaneously.

Tail accessory 6 is threaded connection with plug 1, and the zone design that tail accessory 6 contacts with interior injection molded layers 7 has a protuberance 5, and this protuberance 5 has realized that tail accessory 6 is connected with inlaying of interior injection molded layers 7, further improves the stability of assembly.Tail accessory 6 right parts shown in the figure have been designed to square waveform, the place depression that interior injection molded layers 7 is corresponding with the party's wave regions, and interior like this injection molded layers 7 consists of an annular groove 15 jointly with the square waveform zone.In annular groove 15, steel wire can be stuck in the recess in square waveform zone corresponding to the recess section under the effect of pressure, well fixed.More excellent, afterbody can also be provided with longitudinal type bayonet socket 10 in the square waveform zone, and armouring wire protective layer 11 steel wires one end is stuck in the bayonet socket 10, and fixation is better, has further strengthened tensile strength, has improved reliability.
