[0039] The time service unit 200 obtains a clock signal by means of an antenna to obtain satellite signals sent by the clock source, and transmits the clock signal to the base station 300, so that the base station has the same clock precision as the clock source, and all wireless base stations can have the same clock precision.

[0042] Further, the data line is connected with a connector 400, the connector 400 is connected with the data interface 202, and the connection mode is detachable connection.

[0043] Embodiment 2

[0044] Reference Figures 1 to 8 For the second embodiment of the application, the embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0045] The data interface 202 is provided with a jack 202a, the jack 202a is internally provided with an annular clamping groove 202b, the annular clamping groove 202b has a diameter greater than that of the jack 202a, and the data interface 202 is internally provided with a first wiring end 202c; the first wiring end 202c is a connection end of the general data line.

[0046] The connector 400 comprises a connector seat 401, which is provided with a connector post 401a capable of being embedded into the jack 202a when connected.

[0047] The connector post 401a is provided with a connector hole 401b, in which a second connector end 402 is arranged. The second connector end 402 is also a connection end of a universal data line, i.e. when the connector seat 401 and the jack 202a are connected, the second connector end 402 and the first connector end 202c are connected to transmit signals and current.

[0048] The end surface of the connector post 401a is symmetrically provided with two rotating holes 401c; the end surface of the connector post 401a is connected with two chucks 403, which are semicircular, and the two chucks 403 can form a complete circle to cover the end surface of the connector post 401a; the chuck 403 is provided with a rotating shaft 403a embedded into the rotating hole 401c, and the two chucks 403 are arranged along the circumferential array.

[0049] It should be noted that the rotating shaft 403a is eccentrically arranged on the chuck 403, and preferably, when the two chucks 403 form a complete circle, the side surfaces of the two chucks 403 coincide, and at this time, the included angle between the connecting line of the two rotating shafts 403a and the coinciding side surface of the chuck 403 is 45°, so that when the chuck 403 rotates, an opening will appear between the two chucks 403, and when the connector post 401a is inserted into the jack 202a, the deflection of the chuck 403 can enable the connector seat 401 to be connected with the data interface 202.

[0050] The connector hole 401b is provided with a cylinder 401d, the outer periphery of the second connector end 402 is provided with a protrusion 402a, the protrusion 402a and the end of the cylinder 401d away from the chuck 403 are provided with a first spring 404, and the cylinder 401d is provided with a limiting table limiting the protrusion 402a, so that when the two chucks 403 are separated, the second connector end 402 will be popped out and connected with the first connector end 202c under the action of the first spring 404.

[0051] The end of the second connector end 402 connected with the first connector end 202c is provided with a tapered surface 402b, so that when the two chucks 403 are reset, the opening width in the middle will be reduced, and at the same time, the tapered surface 402b will be squeezed to separate the second connector end 402 from the first connector end 202c.

[0052] Further, the inside of the wiring hole 401b is provided with an annular groove 401e which is penetrated by the rotating hole 401c, the rotating shaft 403a is provided with a first gear 403b outside, the wiring hole 401b is provided with a hollow rotating part 405 inside, the rotating part 405 is provided with a second gear 405a at one end, the second gear 405a is embedded in the annular groove 401e and meshes with the first gear 403b, so that the chuck 403 is deflected by driving the rotating part 405.

[0053] The wiring hole 401b is provided with a hollow moving part 406 inside, the moving part 406 can move axially in the wiring hole 401b, the moving part 406 is provided with a spiral groove 406a outside, the rotating part 405 is provided with a boss 405b inside, the boss 405b is embedded in the spiral groove 406a, the other end of the moving part 406 and the end face of the wiring hole 401b are provided with a second spring 406b, and it should be noted that when the chuck 403 is composed of a circle, the second spring 406b is in a compressed state, when the second spring 406b is stretched, the moving part 406 is pushed to drive the rotating part 405 to rotate.

[0054] It should be noted that the elastic force of the second spring 406b is much greater than that of the first spring 404.

[0055] Among them, the rotating hole 401c is provided with a cylindrical groove 401f, the rotating shaft 403a is provided with a cylindrical block 403c embedded in the cylindrical groove 401f, which can limit the axial offset of the rotating shaft 403a.

[0056] The wiring seat 401 is provided with a circular groove 401g, the end face of the wiring seat 401 is provided with a through hole 401h which penetrates to the circular groove 401g, the circular groove 401g is provided with a sliding block 407, the sliding block 407 is provided with a plug rod 407b which penetrates through the through hole 401h; the sliding block 407 and the end face of the circular groove 401g away from the through hole 401h are provided with a third spring 408, that is, before connection, the third spring 408 pushes the plug rod 407b to extend out of the through hole 401h, and when the wiring seat 401 and the jack 202a are connected, the plug rod 407b will contact the outer end of the jack 202a and shrink into the through hole 401h under the action of pressure until the plug rod 407b completely enters the through hole 401h.

[0057] The through slot 401i is provided between the circular groove 401g and the wire hole 401b, and the insertion block 409 is arranged in the through slot 401i. The outer periphery of the moving piece 406 is provided with a limiting groove 406c, and the end of the insertion block 409 close to the limiting groove 406c is wedge-shaped. Before the connection of the terminal block 401 and the jack 202a, the wedge-shaped end of the insertion block 409 is embedded in the limiting groove 406c, so as to limit the axial movement of the moving piece 406. At this time, the two clamping discs 403 can form a complete circle and cover the end surface of the terminal post 401a. When the insertion block 409 is separated from the limiting groove 406c, the second spring 406b is stretched, the moving piece 406 is pushed to drive the rotating piece 405 to rotate, and then the two clamping discs 403 are opened.

[0058] The sliding block 407 is provided with an opening, and the end of the insertion block 409 is located in the opening. The opening is provided with a slanted groove 407a, and the end of the insertion block 409 is provided with a sliding table 409a embedded in the slanted groove 407a. The inclination direction, length and angle of the slanted groove 407a satisfy that, before the connection of the terminal block 401 and the jack 202a, the end of the insertion rod 407b protrudes out of the through hole 401h. At this time, the sliding table 409a is located at one end of the slanted groove 407a, and the wedge-shaped end of the insertion block 409 is embedded in the limiting groove 406c. When the terminal block 401 and the jack 202a are connected, the insertion rod 407b is pushed to shrink along the axial direction into the through hole 401h, the slanted groove 407a also moves the insertion block 409 away from the limiting groove 406c, until the insertion rod 407b is completely immersed in the through hole 401h. At this time, the clamping disc 403 is also at the bottom of the jack 202a, the insertion block 409 is completely separated from the limiting groove 406c, and the axial movement of the moving piece 406 is no longer limited. Then, under the action of the second spring 406b, through a series of linkages, the clamping disc 403 is expanded and embedded in the annular clamping groove 202b to form a connection.

[0059] The terminal block 401 is provided with a long slot 401j extending along the axial direction. The moving piece 406 is provided with an operating rod 406d, which passes through the long slot 401j. When it is necessary to pull out the terminal connector 400, the operating rod 406d is actuated to compress the second spring 406b of the moving piece 406. The moving piece 406 moves at the same time, and the clamping disc 403 also shrinks. After the clamping disc 403 is completely shrunk, the terminal block 401 can be pulled out. In the process of pulling out, the insertion block 409 is inserted into the limiting groove 406c again to limit the moving piece 406.

[0060] In the embodiment, the data interface 202 is connected with the data line of the base station 300 through the terminal connector 400, which is convenient and fast. When not connected, the end of the terminal connector 400 is closed, and the connection end is hidden inside to prevent damage to the connection end.
