An embodiment of the utility model provides a pair of equipment transmission assembly who moves looks ware 40 moves the equipment transmission assembly that looks ware 40 and includes: the clamping member 10, the first connecting member 20 and the second connecting member 30. The clamping member 10 is used for fixedly assembling two phase shifters 40 (i.e., a group of phase shifters 40 as illustrated in fig. 1 or 2) arranged one above another. The first connecting member 20 is connected to first pull rods 41 of the two phase shifters 40 (the pull rod positioned at an upper portion in the case 44 of the phase shifter 40 is defined as the first pull rod 41), and the second connecting member 30 is connected to second pull rods 42 of the two phase shifters 40 (the pull rod positioned at a lower portion in the case 44 of the phase shifter 40 is defined as the first pull rod 41).

Referring to fig. 5, fig. 5 is a view illustrating a structure of one of the viewing angles of the clamping member 10 according to an embodiment of the present invention. The clamping member 10 includes two clamping arms 11 disposed opposite to each other, a cross member 12 connecting one ends of the two clamping arms 11, and two connecting arms 13. The two connecting arms 13 are correspondingly connected with the other ends of the two clamping arms 11 one by one, and the two connecting arms 13 are detachably connected.

In the assembly transmission assembly of the phase shifter 40, in the process of assembling with two phase shifters 40 stacked up and down, the two phase shifters 40 stacked up and down are installed in the area formed by the two clamping arms 11, the cross beam 12 and the two connecting arms 13, and the two connecting arms 13 are connected with each other, so that the two phase shifters 40 stacked up and down can be combined together; then, the first connecting member 20 is connected to the first pull rods 41 of the two phase shifters 40, and the second connecting member 30 is connected to the two second pull rods 42 of the phase shifters 40; when the first connecting member 20 moves, the first connecting member 20 can synchronously drive the first pull rods 41 of the two phase shifters 40 to move, so that the electrical tilt angle of the phase shifter 40 in one frequency band (for example, 800M) can be adjusted; when the second connecting member 30 synchronously drives the second pull rods 42 of the two phase shifters 40 to move, the electrical tilt angle of the phase shifter 40 in another frequency band (e.g., 900M) can be adjusted. Thus, the clamping piece 10 can realize the combination mode that the two phase shifters 40 are arranged in an up-and-down overlapping mode, meet the electrical use requirement, and match with the first connecting piece 20 and the second connecting piece 30, and can smoothly carry out the work of the two phase shifters 40.

Thus, the phase shifter 40 can be stably clamped by the clamping arm 11, and the arc-shaped plate 14 between the clamping arm 11 and the cross beam 12 is not easy to break under stress, so that the service life is long.

Specifically, the arc plate 14, the cross beam 12, the clamp arm 11, and the connecting arm 13 are integrated. I.e. integrally formed, for example, by injection molding, forging, die casting, etc. Of course, the arc plate 14, the cross beam 12, the clamping arm 11 and the connecting arm 13 may be separate members, and assembled into a whole by using mounting members, or formed into a whole by bonding, clamping and the like.

The PCB boards 45 of the two phase shifting assemblies are electrically connected through the interposer.

Note that, for one phase shifter 40, there are two tie bars, and the tie bar located at the upper side is defined as a first tie bar 41, and the tie bar located at the lower side is defined as a second tie bar 42.

In the process of assembling the base station antenna with the two phase shifters 40 stacked up and down, the two phase shifters 40 stacked up and down are installed in the area surrounded by the two clamping arms 11, the cross beam 12 and the two connecting arms 13, and the two connecting arms 13 are connected with each other, so that the two phase shifters 40 stacked up and down can be combined together; then, the first connecting member 20 is connected to the first pull rods 41 of the two phase shifters 40, and the second connecting member 30 is connected to the two second pull rods 42 of the phase shifters 40; when the first connecting member 20 moves, the first connecting member 20 can synchronously drive the first pull rods 41 of the two phase shifters 40 to move, so that the electrical tilt angle of the phase shifter 40 in one frequency band (for example, 800M) can be adjusted; when the second connecting member 30 synchronously drives the second pull rods 42 of the two phase shifters 40 to move, the electrical tilt angle of the phase shifter 40 in another frequency band (e.g., 900M) can be adjusted. Thus, the clamping piece 10 can realize the combination mode that the two phase shifters 40 are arranged in an up-and-down overlapping mode, meet the electrical use requirement, and match with the first connecting piece 20 and the second connecting piece 30, and can smoothly carry out the work of the two phase shifters 40. Compared with the traditional assembly transmission mode of the phase shifter 40, the occupied space of the phase shifter 40 in the length direction can be reduced, so that the cable 48 can be conveniently laid, the cost can be reduced, and the intermodulation stability can be improved.

Referring to fig. 3 and 4, further, the embodiment of connecting the tie bar to the two dielectric plates on both sides of the PCB 45 is as follows: the pull rod is provided with two connecting portions 46, and the two connecting portions 46 are correspondingly connected with two dielectric plates positioned on two sides of the PCB 45 respectively.

Referring to fig. 1 and 2, two wiring slots 47 and a weight-reducing slot 43 between the two wiring slots 47 are further disposed on two opposite outer walls of the housing 44. The cables 48 of the phase shifter 40 are disposed in the wiring duct 47. When the two clamping members 10 are clamped on the phase shifter 40, the cable 48 installed in the cable slot 47 can be clamped as far as possible at a position where the cable 48 does not interfere with the cable slot 47, and an avoiding hole for avoiding the cable 48 can be formed in the clamping arm 11, so that the cable 48 can pass through the avoiding hole when being led out from the cable slot 47, and therefore the cable is not affected by the clamping members 10 and can be conveniently wired.

It should be noted that, the above-mentioned clamping member 10, the first connecting member 20, the second connecting member 30 and the supporting base 50 are specifically insulating members, such as plastic members, rubber members or insulating members made of other materials, and are not limited herein, and are configured according to actual requirements, so as to avoid adverse effects on signals of the base station antenna.
