DETAILED DESCRIPTION

[0041] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the utility model, but the embodiments of the utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the utility model, rather than all of the embodiments.

[0043] Reference Figures 1 to 13 As shown, this embodiment provides a phase shifter, including a phase shifter cavity structure 1.

[0044] At least one wire groove 11 extending along the length direction of the phase shifter cavity structure 1 is arranged on the outer side wall of the phase shifter cavity structure 1 , the opening of the wire groove 11 is away from the inner cavity of the phase shifter cavity structure 1 , and the wire groove 11 is used to pass the cable 2 of the phase shifter.

[0045] An ion beam vacuum coating layer 12 is provided in at least a portion of the cable trough 11 , and the ion beam vacuum coating layer 12 is used for welding connection with the cable 2 .

[0046] When implementing it, refer to Figure 1 As shown, a wire groove 11 can be provided on an outer side wall of the phase shifter cavity structure 1. The wire groove 11 extends along the length direction of the phase shifter cavity structure 1. Specifically, the wire groove 11 can be provided along the outer side wall of the phase shifter cavity structure 1. Figure 1 In addition, the wire groove 11 can be set to be at least one or more. When multiple wire grooves 11 are set, the multiple wire grooves 11 can be spaced apart along the thickness direction of the phase shifter cavity structure 1. The specific thickness direction can be referred to Figure 1 The z direction is shown.

[0047] Specifically, the opening of the wire slot 11 is away from the inner cavity of the phase shifter cavity structure 1, so that it is convenient for the cable 2 to pass through the opening and be arranged in the wire slot 11, so as to play the role of fixing, guiding and managing the cable 2.

[0048] An ion beam vacuum coating layer 12 is provided in at least a portion of the wire slot 11 . The ion beam vacuum coating layer 12 is used to be welded to the cable 2 , so as to reliably fix the cable 2 in the wire slot 11 .

[0049] It should be noted that compared with the problems of environmental pollution and unsightly caused by the electroplating process in the prior art, the method of forming the ion beam vacuum coating layer 12 by the ion beam vacuum coating process can form an ion beam vacuum coating layer 12 with a smooth and beautiful surface, and will not cause chemical pollution, thus being conducive to environmentally friendly processing operations.

[0050] In addition, with respect to the problem of complicated procedures caused by the need to perform de-plating treatment on the parts that do not need to be plated when local electroplating is used in the prior art, the ion beam vacuum coating process can perform point-to-point coating on the parts that need to be plated in a targeted manner, thereby making the coating more flexible and less costly, and is beneficial for protecting the coating area from unnecessary oxidation, that is, local coating treatment can be achieved on the parts that need to be plated, so there is no need for subsequent de-plating process, thereby simplifying the operation and reducing costs.

[0051] The phase shifter provided in this embodiment includes a phase shifter cavity structure 1, and at least one wire groove 11 extending along the length direction of the phase shifter cavity structure 1 is provided on the outer wall of the phase shifter cavity structure 1, the opening of the wire groove 11 is away from the inner cavity of the phase shifter cavity structure 1, and the wire groove 11 is used to pass the cable 2 of the phase shifter. An ion beam vacuum coating layer 12 is provided in at least part of the wire groove 11, and the ion beam vacuum coating layer 12 is used to be welded and connected with the cable 2. In other words, by providing the ion beam vacuum coating layer 12 in the wire groove 11 of the outer wall of the phase shifter cavity structure 1, the ion beam vacuum coating layer 12 can be directly welded and connected with the cable 2, thereby avoiding the problem of increasing structural complexity, cost and weight caused by adding additional welding parts to the phase shifter cavity structure 1 for welding with the cable 2. In addition, the ion beam vacuum coating layer 12 is formed by an ion beam vacuum coating process. Compared with the electroplating process, the ion beam vacuum coating process is relatively low-carbon and does not emit chemical exhaust gas and waste, which is beneficial to environmental protection. Moreover, since the phase shifter cavity structure 1 is subjected to an electroplating-free treatment, the loss of the phase shifter cavity structure 1 can also be reduced, thereby reducing energy consumption. In addition, due to the electroplating-free treatment, the problem of poor appearance caused by the heat melting of the coating during welding with the cable 2 is also avoided.

[0052] In some embodiments, the ion beam vacuum coating layer 12 is a copper ion vacuum coating layer or a nickel ion vacuum coating layer. That is, the coating substrate selected for ion beam coating can be pure copper, or can also be a metal with good welding fluidity such as pure nickel. The specific material of the coating substrate selected can be a pure metal with a purity of about 95%-99.99%.

That is, along the x direction, a first sub-wire groove 111 is arranged, followed by a second sub-wire groove 112, and then another first sub-wire groove 111 is arranged, and so on, thereby forming a completed wire groove 11.

For example, when an ion beam vacuum coating layer 12 is provided in the second sub-line groove 112, the outer contour of the ion beam vacuum coating layer 12 is matched with the inner contour of the second sub-line groove 112.
