Abstract

The utility model relates to a coaxial connector for a digital wire distributing frame which is a core component in the communication equipment digital distribution frame. The coaxial connector is assembled on a unit plate, and then is arranged on the machine frame, and an inner joint assembly is inserted into an outer joint assembly to form; the inner joint assembly is formed by that an insulated conducting wire is assembled on the inner joint, and two inner joint needles with an upper and a lower needle stands and a test needle with the needle stand are connected into integration; an outer shell which has an inner card and is connected with a spring and the inner joint with a spring loop are connected into integration and are connected with a fixed block, and a copper pipe type coaxial and single-ended fixed structure is used; the utility model has the advantages of small shaft center distance, miniaturized design and small size. After a whole machine is assembled, the density of a machine frame is raised to increase the capacity of the single machine frame, and the coaxial connector can be matched with the communication equipment with large capacity.

Description

The coaxial connector of digital distribution frame

The utility model relates to a kind of communication equipment, and the core components and parts coaxial connector in the digital distribution frame is assembled in it on cell board earlier, and then is installed in and constitutes digital distribution frame on the frame.

Now in the world as the coaxial connector of Japanese NEC similar products, adopt the cable type coaxial configuration, its distance of shaft centers is long to be 117mm, and it is less to assemble the back capacity, and capacity is if will strengthen, and unit quantity will increase.It is also big to take machine room area, has increased the capital expenditure of telecommunication bureau, the cost height.

The purpose of this utility model is to provide a kind of coaxial connector of digital distribution frame, has realized miniaturization, distance of shaft centers weak point, and unit volume is little, has improved the single chassis capacity, has reduced production cost, reduces capital expenditure.

The utility model is achieved in that the coaxial connector of digital distribution frame is by constituting in the nipple assembly insertion coupling assembly, and described nipple assembly will be installed on the nipple by insulated conductor, and have upper and lower needle stand two nipple pins, the band needle stand testing needle fuse, and the shell of clamping spring links into an integrated entity with the nipple that has spring coil in having, and connects and composes with fixed block.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

The stairstepping through hole is arranged in the middle of the coupling (5), i.e. 7 Elastic Contact places, two ends are the cylinder that has screw, middle for conical.

Housing (3) has a groove, upper port that chamfering is arranged for having the pipe of screw in the middle of the outer surface, and feather edge has a flange.

Clamping spring (4) on the opening annulus of uniform large and small hock is arranged.

Contact spring (7) on uniform 7 strip through holes are arranged, i.e. 7 Elastic Contact places, an and opening, upper end are arranged on the periphery is the cylinder of cydariform are as Fig. 6,7.

External scalp acupuncture (8) is fixed on the needle stand (9), and is installed in the contact spring (7), and contact spring (7) is close to housing (3), and coupling (5) is installed in the lower end, with housing (3), coupling (5) connects into whole coupling assembly, as Fig. 2 with screw (10).

Shell (1) is a cylindrical shape, and there is an opening one side, lower end, and one side has a screw relatively, and upper port has a chamfering.

Nipple (2) is the H pipe that communicates, three end openings wherein, and an end is fastened with lid (15), and the lower end is symmetrical substantially.

Nipple pin (16) is fixed in the needle stand that is fused by upper and lower needle stand (17), (20).

Two nipple pins (16) with upper and lower needle stand (17), (20), the testing needle (12) of band needle stand (13), tightly be embedded in three openends on the nipple (2) respectively, and two nipple pins (16) and testing needle (12) welding be fixed into one with insulated conductor (14).

The shell (1) of clamping spring (11) in will having, tightly be enclosed within on the end of nipple (2), and be screwed and link into an integrated entity, connect spring coil (18) back at the end in addition of nipple (2) and insert fixed block (6), connect into whole nipple assembly, as Fig. 3.

The nipple assembly inserted respectively in the two coupling assemblies constitute coaxial connector, as Fig. 1.

With six groups of coaxial connectors, be connected with two socket apertures on the unit of plastic (21) respectively, and be fixed on the unit of plastic (21) with the screw (19) on its fixed block (6) is single-ended, constitute the cell board parts, as Fig. 4,5.

A plurality of cell board parts are installed on the fixed head constitute cell board, be installed in again and be assembled into digital distribution frame on the frame.

The utility model is compared with prior art: because this coaxial connector adopts the copper pipe type coaxial configuration, and axle The heart only has the Miniaturization Design of 16mm apart from little, is the cable type coaxial configuration than Japanese NEC similar products, axle The heart is apart from being that 117mm is much smaller, greatly improved frame density after making it to be assembled into complete machine. Widen 1. in frame 3 times, and in the identical situation of other size, capacity is 12 times of japanese product, for telecommunication bureau saves A large amount of machine rooms spaces, and the elasticity that clamping, contact spring in outer, the nipple assembly are designed to hock shape Contact structures have reduced contact resistance. And component size is little, and be single-ended fixed form, namely only have an end Fixed block is arranged. Therefore adopt the fixing structural volume of both-end little than japanese product, number of spare parts will be lacked. By Greatly dwindle in component size, thus the corresponding minimizing of distribution capacity, and defeated speed improves greatly, the while circuit Between antijamming capability also significantly strengthen.
