Description

Technical Field

[0001] The utility model belongs to the technical field of high-frequency heads, and in particular relates to a high-frequency head shell structure with a limiting structure. Background Art

[0002] The high-frequency head is a device used by satellite TV to receive high-frequency signals and demodulate video information. It is also the first part of the public channel and is installed on the satellite receiver through a bracket.

[0003] The high-frequency head generally includes an outer shell and an internal aluminum shell body. The aluminum shell body has an F-head for connection, and an F-head through-hole is provided at the corresponding position of the outer shell. The aluminum shell body is stabilized in the outer shell. In the existing structure, after the F-head is inserted into the F-head through-hole from the inside, a washer is required to fix the F-head and the F-head through-hole, that is, to stabilize the aluminum shell body in the outer shell. This fixing method has poor stability and also requires a washer. Utility Model Content

[0004] The utility model provides a high-frequency head shell structure with a limiting structure, which can solve the problems pointed out in the background technology.

[0005] A high-frequency head shell structure with a limiting structure includes a shell body, the shell body includes an end plate and an F-head through hole, a limiting guide assembly is provided on the corresponding position of the inner side surface of the end plate and the F-head through hole, the limiting guide assembly includes a push-in limiting guide located at the distal end and a limiting fixing member located at the proximal end, the pushing-in limiting guide member pushes the upper end of the aluminum shell body into a limiting guide, so that the F-head on the aluminum shell body and the F-head through hole are correspondingly penetrated during the pushing process, and the corresponding position of the upper end of the aluminum shell body is introduced into the limiting fixing member by pushing the limiting guide member, and is limited and fixed by the limiting fixing member.

[0006] Preferably, the limiting fixing member has at least two limiting points, and a corner of the upper end of the aluminum shell body is limited by the at least two limiting points.

[0007] Preferably, the limiting fixing member is an "L"-shaped limiting fixing member.

[0008] Preferably, the push-in limit guide is a push-in limit guide plate, which is arranged obliquely with respect to the "L"-shaped limit fixing member.

[0009] Preferably, the push-in limiting guide plate is an arc-shaped plate.

[0010] Preferably, the limiting guide assembly and the shell body are integrally formed.

[0011] Beneficial effects: The utility model provides a high-frequency head shell structure with a limiting structure, which eliminates the traditional gasket fixation and sets a limiting guide component on the inner side of the end plate, which can not only ensure the installation of the aluminum shell body, but also play a stable limiting and fixing role for the aluminum shell body, thereby improving the quality of the product to a certain extent.

[0015] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0016] Example 1:

[0017] like Figure 1 As shown, a high-frequency head shell structure with a limiting structure includes a shell body 1, the shell body 1 includes an end plate 11 and an F-head through hole 12, and a limiting guide component is provided on the corresponding position of the inner side surface of the end plate 11 and the F-head through hole 12. The shell body 1 is generally a plastic part, and the limiting guide component and the shell body 1 can be integrally formed by molding. The limiting guide component includes a push-in limiting guide 21 located at the distal end and a limiting fixing component 22 located at the proximal end. The pushing-in limiting guide 21 pushes the upper end of the aluminum shell body into a limiting guide, so that the F-head on the aluminum shell body and the F-head through hole 12 are correspondingly inserted during the pushing process, and the corresponding position of the upper end of the aluminum shell body is introduced into the limiting fixing component 22 by pushing the limiting guide 21, and is limited and fixed by the limiting fixing component 22.

[0018] Specifically, the limiting fixing member 22 has at least two limiting points, which limit one corner of the upper end of the aluminum shell body through at least two limiting points. Since the corner corresponding to the upper end of the aluminum shell body is generally a right angle, the limiting fixing member 22 can be an "L"-shaped limiting fixing member, and the bending portion of the "L"-shaped limiting fixing member close to the F-head through hole 12 is arranged parallel to the axial direction of the F-head through hole 12.

[0019] The push-in limit guide 21 is a push-in limit guide plate, which is tilted with the "L"-shaped limit fixing piece. The tilted setting makes its motion trajectory the same as the contact position of the upper end of the aluminum shell body, which is convenient for accurate pushing.

[0020] During the pushing process, a small rotation is generally required, so the pushing limit guide plate is an arc-shaped plate, which matches the motion trajectory of the contact position to facilitate smooth pushing.

[0021] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
