The telecommunication wire terminal
Technical field
The utility model relates to a kind of joint that is used for connecting the telecommunication line.
Background technology
As everyone knows, dock two or many telecommunication lines, normally remove the insulation sheath of connection head earlier, exposed heart yearn is twisted together with pliers, and then wrap insulating tape.This choosing connects method, and not only profile is ugly, and connects trouble, inconvenient operation, and the connection of heart yearn is not firm yet.
Summary of the invention
The purpose of this utility model provides a kind of easy to operate, and can make heart yearn connect firm telecommunication wire terminal.
The technical scheme that realizes above-mentioned purpose is: a kind of telecommunication wire terminal, comprise insulating case, and be set with copper pipe in the insulating case, be set with the pipe of holding with a firm grip in the copper pipe, have the burr hole that is net distribution on the tube wall of the pipe of holding with a firm grip, and the inboard in burr hole has burr.
After adopting technique scheme, owing to be set with copper pipe in the insulating case, be set with the pipe of holding with a firm grip in the copper pipe, hold with a firm grip and have the burr hole that is net distribution on the tube wall of pipe, and the inboard in burr hole has burr, when connecting the telecommunication line, as long as two of will dock or many telecommunication the end of a thread portions remove insulation sheath, insert in the cover of holding with a firm grip then in the lump, with the instrument pincers that connector clamp is flat, the heart yearn of need butt joint can be fixed together, easy to operate, it is firm that the inboard burr of pipe of holding with a firm grip can guarantee that heart yearn connects, and can not come off.In addition, above-mentioned joint also has simple, the advantages such as cost is low, good looking appearance of manufacturing.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, 2, 3, a kind of telecommunication wire terminal comprises insulating case 4, is set with copper pipe 2 in the insulating case 4, is set with the pipe 3 of holding with a firm grip in the copper pipe 2, have the burr hole 4 that is net distribution on the tube wall of the pipe 3 of holding with a firm grip, and the inboard in burr hole 4 has burr 3-1.The method of managing the burr hole 4 employing punching out on 3 of holding with a firm grip is made.
Shown in Fig. 4,5, copper pipe 2 is rolled by copper sheet and forms, and the joint of copper pipe 2 is a zigzag seam 7.When with instrument pincers with connector clamp when flat, sawtooth can block heart yearn 5, increases grip force, it is firm to guarantee that further heart yearn 5 connects, and can not come off.
Shown in Fig. 2,3, the pipe 3 of holding with a firm grip is a square tube of being made by copper sheet, and the joint of copper sheet has opening 6.This structure is convenient to the pipe 3 of holding with a firm grip is inserted copper pipe 2, as long as be used to pinch the pipe 3 of holding with a firm grip, makes opening 6 closures of holding pipe 3 with a firm grip, and the pipe 3 of can will holding with a firm grip inserts copper pipe 2, struts automatically after the pipe 3 of holding with a firm grip inserts copper pipe 2, and swelling can not dropped from copper pipe 2 in copper pipe 2.
During the utility model assembling, the pipe 3 of will holding with a firm grip earlier inserts in the copper pipe 2, puts insulating case 1 again on copper pipe 2.During use, the telecommunication line of need butt joints is removed the insulation sheath of head, then exposed heart yearn 5 is inserted to hold with a firm grip in the lump and manage in 3, the employing instrument clamps the flat butt joint of promptly finishing the telecommunication line of connector clamp.
