Description

Technical Field

[0001] The present invention relates to the technical field of power splitters, and in particular to a power splitter that is easy to connect and a method for using the power splitter. Background Art

[0002] The full name of the power splitter is power divider. It is a device that divides the energy of one input signal into two or more outputs of equal or unequal energy. It can also conversely combine the energy of multiple signals into one output. In this case, it can also be called a combiner. A certain degree of isolation should be ensured between the output ports of a power splitter. The power splitter is usually divided into one-to-two (one input and two outputs), one-to-three (one input and three outputs), etc.

[0003] The connection ends of conventional one-to-two power splitters are often threaded and matched with threaded caps to achieve the connection between the power splitter and the external line. In actual use, this connection method is often prone to misalignment between the threaded cap and the threaded end. Not only is the connection unstable, but it is also easy to damage the threaded end, resulting in the power splitter being unable to connect normally and stably with the external line. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In response to the deficiencies in the prior art, the present invention provides a power divider that is easy to connect and a method for use, which solves the problem that in actual use, the threaded cap and the threaded end are often not aligned when tightened, which not only makes the connection unstable, but also easily damages the threaded end, resulting in the power divider being unable to connect normally and stably with the external line.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a power divider that is easy to dock, comprising a power divider body and three docking caps, wherein docking joints are provided on the top and the bottoms of the left and right sides of the power divider body, wherein the docking joints cooperate with the docking caps, wherein three sets of expansion joints are provided throughout the surface of the power divider body, and wherein the expansion joints are provided inside the docking joints, wherein elastic components adapted to the expansion joints are provided inside the docking joints, wherein the inner surface of the docking caps is in sliding contact with the outer surface of the docking joints, wherein a limiting ring is fixedly installed inside the docking caps, wherein the outer surface of the limiting rings is in sliding contact with the inner surface of the docking joints, and wherein the inner surface of the limiting rings is provided inside the limiting rings, wherein the contact guides adapted to the expansion joints are provided;

[0008] A guide rod is fixedly installed on the outer periphery of the limiting ring, and a slot, an arc groove and a retention groove adapted to the guide rod are opened on the surface of the docking joint, and the slot and the retention groove are connected through the arc groove.

[0009] By adopting the above technical solution, the coordinated arrangement of the guide rod, slot, arc groove and retention groove is utilized to provide precise guidance for the connection between the docking cap and the docking joint, ensuring that the docking cap and the docking joint are precisely docked. At the same time, with the coordination of the elastic component, telescopic joint and contact guide, the elastic component is utilized to limit the limiting ring to ensure that the guide rod is stably retained in the retention groove, thereby achieving stable docking between the docking cap and the docking joint. While having a simple structure, it realizes convenient docking between the external line and the power divider body.

[0010] The present invention is further configured as follows: the telescopic joint includes a connecting post and an expansion tube, the expansion tube is sleeved and slidably installed on the surface of the connecting post, and the connecting post is fixedly connected to the surface of the power divider body.

[0012] By adopting the above technical solution and utilizing the cooperation between the contact ring and the expansion tube, the expansion tube is driven to move on the connecting column during the movement of the contact ring, and the first spring and the fixing ring are configured to squeeze the first spring, and the elastic force of the first spring is used as the power. After the docking cap is loosened, the first spring can push the contact ring to cause the limit ring to drive the guide rod to stay in the retention groove, thereby achieving stable snap-fitting between the docking cap and the docking head.

[0013] The present invention is further configured as follows: the contact guide includes a guide head and an isolation ring, the guide head is used in conjunction with the expansion tube, one side of the guide head is fixedly connected with a wire and a rubber ring from the inside to the outside in sequence, and the isolation ring is fixedly installed inside the limit ring.

[0014] The present invention is further configured as follows: an assembly hole is opened on one side of the docking cap, an elastic sleeve is provided inside the assembly hole, one end of the wire passes through the elastic sleeve and extends to the outside of the elastic sleeve, and the side of the rubber ring away from the guide head contacts one side of the isolation ring.

When the limit ring contacts the contact ring, the expansion tube contacts the guide head. The limit ring pushes the contact ring to drive the expansion tube to move on the connecting column. The contact ring squeezes the first spring until the guide rod moves into the arc groove. The docking cap is rotated to move the guide rod along the arc groove into the retention groove. The docking cap is loosened. The first spring pushes the contact ring to move. The contact ring pushes the limit ring to make the guide rod slide along the retention groove.

[0022] Step 3, final assembly: Before putting the docking cap on the docking head in step 2, pull the handle, and the handle drives the two pressure plates to move the first arc pressure block and the second arc pressure block until the pin moves into the slot. During the process, the pressure plate squeezes the second spring. After the guide rod moves into the retention groove, release the handle, and the second spring squeezes the pressure plate, causing the pressure plate to drive the first arc pressure block and the second arc pressure block to move, allowing the pin to pass through the slot and be inserted into the arc blind groove.
