Description

Technical Field

[0001] This utility model relates to a filter that facilitates cable installation. Background Technology

[0002] With the development of mobile communication networks, the requirements for the weight of metal filters are becoming increasingly stringent. Due to the complexity of the design and the size of the cavity, some products require the use of transmission cables to connect the connectors internally.

[0003] Existing connector cables cannot guarantee against the risk of performance failure in the metal filter welding environment. Therefore, it is necessary to design connector cables that are installed after the filter cover plate is welded in order to ensure connector performance. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a filter that facilitates cable installation, comprising: a cavity, and an adjustment cover plate disposed on the top of the cavity;

[0005] The debugging cover plate is provided with a welding clearance hole for welding the inner core of the cable to the inside of the cavity;

[0006] The debugging cover plate is also equipped with a small shielding cover plate for sealing the welding avoidance hole.

[0007] Preferably, the outer surface of the debugging cover plate is further provided with a thinning area surrounding the welding avoidance hole and for the shielding small cover plate to be inserted and spliced.

[0008] Preferably, the shielding cover is fixed to the debugging cover by multiple screws.

[0009] Preferably, the thinned area is provided with a plurality of threaded blind holes for mounting screws.

[0010] Preferably, the shielding cover plate is provided with a plurality of mounting holes for mounting screws.

[0011] Preferably, the inner surface of the shielding cover plate is provided with a protrusion for sealing the welding avoidance hole.

[0012] Preferably, the cavity is a metal cavity.

[0013] The advantages and beneficial effects of this utility model are: it provides a filter that is easy to install cables and can take into account both performance reliability and appearance.

[0014] First, the inner core of the cable is welded to the inside of the cavity through the welding clearance hole. After welding, the shielding cover plate is inserted into the thinned area spliced ​​on the outer surface of the test cover plate. Then, the shielding cover plate is locked and fixed to the test cover plate with multiple screws (the screws pass through the mounting hole of the shielding cover plate and are locked into the threaded blind hole of the thinned area). At this time, the protrusion on the inner surface of the shielding cover plate seals the welding clearance hole. Thus, the appearance is taken into account while ensuring reliable performance.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] The specific technical solution of this utility model is as follows:

[0020] like Figures 1 to 3 As shown, a filter that facilitates cable installation includes: a cavity 1, and an adjustment cover 2 disposed on the top of the cavity 1;

[0021] The debugging cover plate 2 is provided with a welding clearance hole 3 for welding the inner core 10 of the cable to the inside of the cavity 1.

[0022] The debugging cover plate 2 is also provided with a small shielding cover plate 4 for sealing the welding avoidance hole 3;

[0023] The outer surface of the debugging cover plate 2 is also provided with a thinning area 5 surrounding the welding avoidance hole 3 and for the shielding small cover plate 4 to be inserted and spliced.

[0024] The shielding cover plate 4 is fixedly connected to the debugging cover plate 2 by multiple screws 6;

[0025] The thinned region 5 is provided with a plurality of threaded blind holes 7 for mounting screws 6;

[0026] The shielding cover plate 4 is provided with a plurality of mounting holes 8 for mounting screws 6;

[0027] The inner surface of the shielding cover plate 4 is provided with a protrusion 9 for sealing the welding avoidance hole 3;

[0028] The cavity 1 is a metal cavity.

[0029] First, the inner core 10 of the cable is welded to the inside of the cavity 1 through the welding clearance hole 3. After welding, the shielding cover plate 4 is inserted into the thinned area 5 spliced ​​on the outer surface of the test cover plate 2. Then, the shielding cover plate 4 is locked and fixed on the test cover plate 2 by multiple screws 6 (the screws 6 pass through the mounting hole 8 of the shielding cover plate 4 and are locked into the threaded blind hole 7 of the thinned area 5). At this time, the protrusion 9 on the inner surface of the shielding cover plate 4 blocks the welding clearance hole 3. Thus, the appearance is taken into account while ensuring reliable performance.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
