Description
Technical field
The utility model relates to fiber optic communication field, relates in particular to a kind of covered wire cable cold joint clamping device.
Background technology
In recent years, the optical fiber access market of China presented good growth momentum, and optical fiber inserts the focus that has become in the optical communication field.Insert in the engineering at optical fiber, close user's house wiring is the most complicated link, and the bending property of conventional inside cable, tensile property can not satisfy the demand of FTTH (Fiber to the home) house wiring.2002, Fiberhome telecommunication developed " indoor suspension type wiring optical cable " and is commonly called as " covered wire cable " according to the market demand.
The access of covered wire cable in the past is to use mechanically splicing optical fiber; but because the external diameter of covered wire cable is bigger; expose optical fiber so can only peel off the oversheath and the reinforcement of covered wire cable outside; by the connector grip optical fiber; because the thinner this holding force of optical fiber can only reach about 400G, and the exposed shortage protection of the bare wire at two ends.Compare with common optical fiber, the advantage of covered wire cable has: covered wire cable has good bending resistance; The splicing point stretching resistance of covered wire cable is big more a lot of than ordinary optic fibre.Yet, connect covered wire cable with present mechanically splicing optical fiber, can not bring into play its advantage.
Summary of the invention
Technical scheme to be solved in the utility model provides a kind of simple in structure, a kind of covered wire cable cold joint clamping device that the splicing point stretching resistance is big, aimed at accurately and be applicable to batch process.For this reason, the utility model by the following technical solutions: it comprises lower cover, and loam cake is provided with mechanically splicing optical fiber in the housing that lower cover and loam cake surround, and described clamping device is provided with rubber-insulated wire oversheath fixed mechanism respectively outside the two ends of mechanically splicing optical fiber.
When adopting technique scheme, the utility model also can adopt following further technical scheme:
Described lower cover material can be a metal or nonmetal.Described loam cake material can be that metal also can be nonmetal.
Described rubber-insulated wire oversheath fixed mechanism is for gripping mechanism.
Described gripping comprises that socket and clinching, described socket are arranged on and covers under described.
Be arranged with 4 pins and 2 guiding pin around the described clinching, described socket is provided with groove or the hole that is connected with pin, and described socket also is provided with the gathering sill that cooperates with the pin that leads.
Described loam cake and lower cover snapping, and described socket and clinching can be compressed.
Between mechanically splicing optical fiber and rubber-insulated wire oversheath fixed mechanism, be provided with optical cable and cross groove.
Because adopt the technical solution of the utility model, the utility model has following advantage: 1. simple in structure, cost of manufacture is low; 2. the splicing point stretching resistance is big, and the outer stretching resistance representative value of each joint is 5Kg, and maximal value can reach 10Kg; 3. operation is very simple, and for the optical fiber of handling well, 45 seconds just can complete connection work.

Embodiment
With reference to accompanying drawing.The utility model comprises loam cake 4 and lower cover 1, is provided with mechanically splicing optical fiber 2 in the housing that lower cover and loam cake surround, and described clamping device is provided with rubber-insulated wire oversheath fixed mechanism respectively outside the two ends of mechanically splicing optical fiber.
The center section of lower cover 1 is provided with the locating slot 13 of placing mechanically splicing optical fiber 2, places described mechanically splicing optical fiber 2 in the described locating slot 13, and mechanically splicing optical fiber 2 is used for aiming at optical fiber.
In the present embodiment, described rubber-insulated wire oversheath fixed mechanism adopts and grips mechanism, is used for gripping the oversheath 52 of covered wire cable 5.Described gripping comprises that socket 12 and clinching 30, described socket 12 are arranged on and covers under described.Be arranged with 4 pins 31 and 2 guiding pin 32 around the described clinching, described socket is provided with groove or the hole 14 that is connected with pin 31, and described socket also is provided with the gathering sill 15 that cooperates with the pin 32 that leads.
In the present embodiment, described loam cake and lower cover snapping.The centre of described lower cover 1 and the part at two ends are provided with snap seats 11, are used with buckle 41 in the loam cake.After loam cake 4 buckles in the snap seats 11 by buckle 41, also clinching 30 is continued to be pressed on the socket, thereby tightly the clamping covered wire cable makes optical fiber can bear bigger pulling force to keep the stable of optical parametric, improved optical property.
The structure of covered wire cable as shown in Figure 5, it comprises optical fiber 51, oversheath 52 and reinforcement 53.Between mechanically splicing optical fiber and rubber-insulated wire oversheath fixed mechanism, be provided with optical cable and cross groove 16.
In project implementing process, mechanically splicing optical fiber 2 is put into the connector locating slot 13 of lower cover 1, strip two covered wire cables by specification, two ends from connector 2 are inserted into the connector 2 respectively, the optical cable that the two ends of covered wire cable are placed in lower cover 1 two ends is respectively crossed in the groove 16 again, and it is little curved that the part of covered wire cable in lower cover keeps; Insert clinching 30 in the socket 12 in lower cover 1 and compress covered wire cable; Cover loam cake at last, the buckle 41 of loam cake buckles in the snap seats 11 of lower cover, and loam cake 4 compresses clinching 3 simultaneously.
The utility model uses the treated optical fiber of end face, both can improve optical property, can reduce cost again.
