AI Technical Summary
The existing high-frequency head housing has low production efficiency, complex mold design, and difficulty in adapting to the connection of F-head housings of different specifications.
The main housing and the F-head housing are die-cast separately and then fixed together by screws, which simplifies the mold design and allows the main housing to be adapted to F-head housings of different specifications.
It improves production efficiency, reduces production costs, and supports the production of multiple main shells using a unified mold, making manufacturing easier.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of high-frequency head technology, and specifically relates to a novel high-frequency head housing structure. Background Technology
[0002] A low-frequency head (LNB) is a device used by satellite television to receive high-frequency signals and demodulate video information. It is also the first part of the common channel and is mounted on the satellite receiver by a bracket.
[0003] In the existing technology, the housing of the high frequency head is generally formed by die casting. The housing of the high frequency head generally consists of a main housing and an F-head housing. However, since both the main housing and the F-head housing have through holes, the core pulling device needs to be set in two directions on the molding die. Therefore, a molding die can generally only die cast a maximum of 4 high frequency head housings at a time, resulting in low production efficiency and a relatively complex design structure of the molding die. Utility Model Content
[0004] This invention provides a novel high-frequency head housing structure that can solve the problems pointed out in the background art.
[0005] A novel high-frequency head housing structure includes a main housing and an F-head housing. The main housing and the F-head housing are die-cast integrally. After die-casting, the F-head housing is fixed on the main housing. The F-head housing includes a fixing connecting plate and an F-head tube. The fixing connecting plate is fixed on the main housing.
[0006] Preferably, the fixed connecting plate is fixed to the corresponding groove in the main housing by screws.
[0007] Beneficial effects: This utility model provides a novel high-frequency head housing structure, in which the main housing and the F-head housing are die-cast separately and then connected and fixed in a secondary manner. Multiple main housings can be die-cast at one time, which can greatly improve work efficiency and the mold design is relatively simple. In addition, since the F-head housing and the main housing are connected in a secondary manner, the main housing can be connected and adapted to F-head housings of different specifications. The main housing can be produced with a uniform mold to a uniform specification, which also reduces production costs to a certain extent and facilitates manufacturing. Attached Figure Description

[0009] Explanation of reference numerals in the attached figures:
[0010] The following are the labels in the diagram: Main housing 1; Tank 11; F-head housing 2; Fixed connecting plate 21; F-head tube 22; Screw 23. Detailed Implementation
[0011] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.
[0012] Example 1:
[0013] like Figure 1 As shown, a novel high-frequency head housing structure includes a main housing 1 and an F-head housing 2. The main housing 1 and the F-head housing 2 are die-cast integrally. After die-casting, the F-head housing 2 is fixed on the main housing 1. The F-head housing 2 includes a fixing connecting plate 21 and an F-head tube 22. The fixing connecting plate 21 is fixed on the main housing 1. Specifically, the fixing connecting plate 21 is fixed in the corresponding groove 11 of the main housing 1 by screws 23, that is, at the outer end of the circuit board groove.
[0014] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
