DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the embodiments described are only part of the embodiments of this patent, not all of them. Based on the embodiments of this patent, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this patent.

[0020] See also Figure 1-2 This patent provides a technical solution: a microwave mixer module with dustproof connection, including a microwave mixer 1 and a connecting cable 2, a connecting port 3 is installed on the side wall of the microwave mixer 1, and the connecting cable 2 is inserted and installed in the connecting port 3;

[0021] The microwave mixer 1 proposed in this article is a prior art. The microwave mixer 1 generally has three ports, namely the connection port 3 in this article, which are generally two input ports and one output port. Generally, in a receiver, one input port receives a weak spatial signal and amplifies it through a low-noise amplifier (LNA) module. The other input port receives a local oscillator (LO) signal provided by a local oscillator. The output port outputs the intermediate frequency required for low-frequency processing.

[0022] A socket 4 is formed on the side wall of the connection port 3, and a convex ring 5 is installed in the socket 4. The connection cable 2 can be inserted and installed in the socket 4. A baffle 6 is installed on the side wall of the connection cable 2. A sealing rubber ring 7 is installed on the side wall of the baffle 6. The sealing rubber ring 7 is arranged on the outside of the connection cable 2 and can fit the side wall of the convex ring 5.

[0023] The sealing rubber ring 7 can ensure the sealing of the connection between the connecting cable 2 and the connecting port 3, thereby preventing the ingress of external dust, playing a dust-proof effect, preventing dust from affecting the stability of the connection between the two, and preventing the occurrence of a loose connection due to dust;

[0024] A fixing sleeve 8 is sleeved on the outer side of the connecting cable 2 . The inner side wall of the fixing sleeve 8 is provided with an internal thread. The outer side of the connecting port 3 is provided with an external thread. The fixing sleeve 8 can be rotatably installed on the outer side of the connecting port 3 .

[0025] Specifically, the sealing rubber ring 7 includes a ring body 71, an air cavity 72, a through hole 73 and a valve core 74. The ring body 71 is fitted on the side wall of the baffle 6. The air cavity 72 is formed in the inner cavity of the ring body 71. The side wall of the baffle 6 is provided with a through hole 73. The through hole 73 passes through the side wall of the ring body 71 and is connected to the air cavity 72. The valve core 74 is inserted and installed in the through hole 73.

[0026] Because an air cavity 72 is provided inside the sealing rubber ring 7 in this article, the sealing rubber ring 7 can be expanded by inflating the air cavity 72, so that the sealing rubber ring 7 fits tightly with the connecting cable 2 to achieve a completely sealed state and prevent dust from entering.

[0027] Specifically, a rotation-stopping mechanism 9 is installed on the side wall of the fixed sleeve 8 , and the rotation-stopping mechanism 9 can fix the fixed sleeve 8 .

[0028] Specifically, the anti-rotation mechanism 9 includes a positioning hole 91, a positioning pin 92 and a connecting rope 93. The side wall of the fixed sleeve 8 is inserted with the positioning pin 92, and the side wall of the connection port 3 is provided with a positioning hole 91. The positioning pin 92 can be inserted into the positioning hole 91. One end of the connecting rope 93 is installed at one end of the positioning pin 92 located outside the fixed sleeve 8, and the other end of the connecting rope 93 is connected to the side wall of the fixed sleeve 8.

[0029] The anti-rotation mechanism 9 can prevent the fixed sleeve 8 from rotating, thereby preventing the connecting cable 2 from falling out of the connecting port 3. The setting of the connecting rope 93 can prevent the positioning pin 92 from being lost, thereby avoiding affecting the fixation of the fixed sleeve 8.

[0030] Specifically, a retaining ring 10 is sleeved on the outer side of the connection port 3. The retaining ring 10 is made of rubber, and the fixing sleeve 8 can fit the side wall of the retaining ring 10.

[0031] The provision of the retaining ring 10 can improve the sealing effect of the connection between the connecting cable 2 and the connecting port 3 .

[0032] Specifically, an annular groove 11 is formed on the side wall of the retaining ring 10 , and the fixing sleeve 8 can be inserted and installed in the annular groove 11 .

[0033] Working Principle: After inserting the connecting cable 2 into the connecting port 3, rotate the fixing sleeve 8 so that it fits with the external thread of the connecting port 3 to fix the connecting cable 2. At this time, the sealing rubber ring 7 on one side of the baffle 6 will contact and be squeezed by the convex ring 5. At this time, due to the squeezing of the convex ring 5 and the baffle 6, the sealing rubber ring 7 will expand laterally, making it fit tightly with the side wall of the connecting cable 2, thereby achieving a good sealing effect and playing a role in preventing dust at the connection;

[0034] In order to improve the sealing effect of the connection, the external air pipe can be connected to the valve core 74, and air can be inflated into the air cavity 72 through the valve core 74 to further expand the sealing rubber ring 7 to achieve a completely sealed state and prevent dust from entering.

[0035] It will be apparent to those skilled in the art that this patent is not limited to the details of the exemplary embodiments described above, and that this patent can be implemented in other specific forms without departing from the spirit or essential characteristics of this patent. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of this patent is defined by the appended claims rather than the foregoing description, and it is intended that all changes that fall within the meaning and range of equivalents of the claims be encompassed within this patent. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
