Description

Technical Field

[0001] The utility model belongs to the technical field of coaxial switches of radio frequency and microwave signal systems, in particular to a micro coaxial switch matrix with corner protection. Technical Background

[0002] Coaxial switch matrices are currently used extensively in RF / microwave systems, such as time multiplexers, time-division channel selection, pulse modulation, transceiver switching, and beamforming. Micro coaxial switch matrices utilize a connection method where the coaxial switch signal connectors and control interfaces protrude from the front and rear panels of the switch module housing. This exposes the coaxial switch connectors directly to the outside of the switch module housing, making them susceptible to bumps and damage during use. Since the coaxial switch signal connectors and control interfaces are precision components, damage from bumps and bumps can directly lead to product failure, shortening the lifespan of the coaxial switch matrix.

[0028] The technical solution of the present utility model will be further described below with reference to the accompanying drawings and specific implementation methods. Example

[0029] Figure 1 This is a structural diagram of a miniature coaxial switch matrix with a protective device, which is equipped with two single-pole eight-throw and one single-pole double-throw switches. It includes a rectangular box body 1, a coaxial switch and a control component arranged in the box body. The box body 1 is provided with a front panel 5 and a rear panel 6. The coaxial switch in the box body has a signal connector 2, which protrudes from the front panel to the outside of the box body. The control component in the box body has a control interface 12, which protrudes from the rear panel to the outside of the box body. Guard feet are also fixedly provided at the front and back of the box body, and the guard feet include a front guard foot 3 provided on the front panel, the extension direction of which is consistent with the protrusion direction of the signal connector, and a rear guard foot 4 provided on the rear panel, the extension direction of which is consistent with the protrusion direction of the control interface. The length of the guard foot is the distance from the plane formed by the outermost end of the guard foot to the panel of the box body where the guard foot is located. From Figure 1 As can be seen, the four front foot guards are the same length, all longer than the length of the signal connector protruding from the front panel; the four rear foot guards are the same length, all longer than the length of the control interface protruding from the rear panel. In addition, the front foot guards are the same length as the rear foot guards.

[0030] Figure 2 yes Figure 1 The left view shows the structure of the front panel of the micro coaxial switch matrix of the present invention. We can see that one single-pole double-throw and two single-pole eight-throw coaxial switches are installed in the box body, and the signal connector 2 protrudes from the front panel 5 to the outside of the box body. The front panel is provided with a front guard foot 3 whose extension direction is consistent with the protrusion direction of the signal connector. The four front guard feet are respectively arranged on the four top corners of the box body, and the guard foot block has a through hole 7.

We can see that four rear guard feet 4 are respectively provided on the four top corners of the rear panel, and the control interface 12 protrudes from the rear panel 6 to the outside of the box body. The extension direction of the rear guard foot 4 is consistent with the protrusion direction of the control interface, and the guard foot block has a through hole 7.

Figure 6 It can be seen that the guard wall is a strip with an L-shaped cross section, and a stopper 9 is provided at the longitudinal end of the guard wall. Figure 5 It can be seen that the stopper 9 blocks the inner corner direction of one end of the L-shaped retaining wall 8. Figure 4 、 5 , 6 both show that the block 9 has a through hole 7 opened in the longitudinal direction of the guard wall that matches the box body. The box body and the foot guard are fixedly connected through the through hole on the block. The foot guard is set at the vertex of the box body, the inner corner end point of the L-shaped guard wall 8 connected to the block 9 is affixed to the vertex of the box body, the L-shaped guard wall is affixed to the two outer facades of the box body, and the block is affixed to the panel of the box body; the length of the block is the length of the foot guard. The block of this embodiment is a right triangular prism with a right triangle bottom surface. The side surfaces corresponding to the two right-angled sides of the bottom triangle coincide with the outer surface of the guard wall, and the side surfaces corresponding to the hypotenuse of the bottom triangle are perpendicular to the box body panel. The through hole passes through the two bottom surfaces of the right triangular prism. The through hole 7 is a stepped hole, which is perpendicular to the box body panel. The guard wall and block in the figure have chamfers. The setting of the chamfers is to match the box body with chamfers and does not affect the connection relationship of the components described in this utility model.

[0033] See also Figure 7 The end corner of the box body 1 is provided with a threaded hole 10 that matches the through hole of the stopper; the straight triangular prism stopper can be connected to the box body by a countersunk step positioning screw.

Countersunk step set screws pass through the through holes of the stopper and the panel fixing holes and screw into the threaded holes of the box body in sequence, fixing the panel between the stopper and the end face of the box body. The box body in the figure has chamfered corners.

[0034] The shape of the stopper is not limited to a right triangular prism with a right triangle bottom surface. For example, the stopper may also be a cylinder with a quarter-circular cross-section, with two side planes coinciding with the outer surface of the retaining wall, a curved surface perpendicular to the box panel, and a through hole penetrating the two bottom surfaces of the cylinder with a quarter-circular cross-section.
