Description

Technical Field

[0001] The utility model relates to the technical field of small antennas, in particular to a small antenna. Background Art

[0002] See also Figure 1 As shown in the figure, the stator and rotor ends of the old version of the slip ring are connected by flanges, and the stator end is connected to the outside world through a wiring terminal (such as DB9), and the external input needs to pass through the wiring trough. Therefore, during debugging or maintenance, if you want to separate the stator and rotor ends, you first need to remove the wiring trough cover, take out the DB9 wiring terminal from the wiring trough, and then you can separate the stator and rotor ends. After debugging or maintenance, when the DB9 wiring terminal is installed back into the wiring trough, it is inconvenient to pull the wire out because the DB9 head is relatively large and the wiring trough is relatively long.

[0025] See also Figure 2 and Figure 3As shown, the utility model provides a small antenna, comprising: a housing 1000 and a connector 200 fixed in the housing 1000. The connector 200 comprises a male connector 210, a female connector 220 and a slip ring body 230; the male connector 210 and the female connector 220 are in board-to-board point contact, the stator wire of the slip ring body 230 is connected to the pin on the male connector 210, and the female connector 220 is connected to the external input plug 221.

[0026] See also Figure 2 and Figure 3 As shown, in one embodiment of the utility model, the housing 1000 includes a base 100, and a first mounting groove 111, a second mounting groove 112 and a third mounting groove 113 are provided on the base 100. The female connector 220 is fixed in the first mounting groove 111, the external input plug 221 is fixed in the third mounting groove 113, and the connection line between the external input plug 221 and the female connector 220 is located in the second mounting groove 112. The stator wire of the slip ring body 230 and the male connector 210 ensure that the slip ring and the connector joint are integrated, the external input plug 221 is connected to the female connector 220, and the female connector 220 is on the base 100. When the base 100 is removed, it is not necessary to remove the slot cover plate on the second mounting groove 112. After installation, the male connector 210 and the female connector 220 can be plugged in to realize power supply and communication. When the slip ring body 230 needs to be repaired or debugged, the connector male head 210 is directly unplugged from the connector female head 220. At this time, there is no need to remove the slot cover plate on the second installation slot 112, nor is there any need to remove the base 100 and the connector female head 220. During installation, only the connector male head 210 and the connector female head 220 need to be plugged into each other, so that disassembly and assembly are convenient.

[0027] See also Figures 4 to 6 As shown, in one embodiment of the utility model, a first force groove 120 and a second force groove 130 are provided on the base 100, and the first force groove 120 and the second force groove 130 are symmetrically arranged. The first force groove 120 and the second force groove 130 are used to provide a force point during transportation. Specifically, the groove width of the first force groove 120 occupies part of the bottom plate space of the base 100 and part of the side plate space of the base 100, and the side plate of the base 100 is arranged in an arc shape, so that the groove depth of the first force groove 120 located on the side of the side plate of the base 100 is less than the groove depth of the first force groove 120 located on the side of the bottom plate of the base 100, forming a height difference, providing space for the detachable handle 300, so that the detachable handle 300 will not cause the antenna housing to be placed unsteadily due to its own thickness after installation. Similarly, the first force groove 120 and the second force groove 130 are symmetrically arranged, and there is no doubt that the groove width and groove depth of the second force groove 130 are set the same as the first force groove 120.

[0028] In one embodiment of the utility model, a first fixed handle 140 and a second fixed handle 150 are further provided on the base 100, and the first fixed handle 140 and the second fixed handle 150 are in a hidden form and fixed integrally with the base 100. A detachable handle 300 is also included, and the detachable handle 300 is connected to the base 100 in a plug-in manner at the first fixed handle 140 or the second fixed handle 150.

[0029] In one embodiment of the utility model, the base 100 is rectangular, and each corner is connected by a circular arc transition. The small antenna also includes an upper cover 400, which is detachably connected to the base 100. The upper cover 400 and the base 100 form a receiving space, and the connector 200 is located in the receiving space.

[0030] In one embodiment of the present invention, the first fixed handle 140 is in the first force groove 120 and fixedly connected to the side plate of the base 100, and the second fixed handle 150 is in the second force groove 130 and fixedly connected to the side plate of the base 100. The first force groove 120 and the second force groove 130 are located on the side of the side plate of the base 100, and the thickness is relatively thin. When carrying and bearing force, if the material of the side plate of the base 100 is not properly selected, it will deform over time. Therefore, by setting a fixed handle and increasing the thickness of the force groove, the service life of the shell is increased and it is convenient for users to apply force.

[0031] In one embodiment of the utility model, the technical solution of the fixed handle is only applicable to short-distance transportation. In actual use, the tools carried when installing the antenna are not only the antenna, but also the corresponding tool box. However, when using the technical solution of the fixed handle, two hands are occupied, and the tool box can no longer be held, and the tool box can only be carried back and forth. If the distance is long, it is time-consuming and laborious. Therefore, the present invention also provides a technical solution of a detachable handle 300. When used over a long distance, the detachable handle 300 is used to carry the antenna, and the detachable handle 300 is removed when installing.

[0032] Specifically, the detachable handle 300 includes a hook head 310, and an extended first connecting rod 320 formed integrally with the hook head 310 and at one end of the hook head 310, and also includes a second connecting rod 330 connected to the first connecting rod 320. The hook head 310 is in a "U" shape, and the other end of the hook head 310 is provided with a chamfer to facilitate plugging and unplugging, and the diameter of the first connecting rod 320 is smaller than the diameter of the second connecting rod 330 to avoid the mismatch between the depth of the first connecting rod 320 and the force groove. Plug-in through holes 1450 are provided at both ends of the first fixed handle 140 and the second fixed handle 150, and extend to the side panels of the base 100. When in use, the chamfered end of the hook head 310 of the detachable handle 300 is inserted into the plug-in through hole 1450, and the user can carry the second connecting rod 330 by hand.
