Description

Technical Field

[0001] This utility model belongs to the field of radio frequency converter technology, and specifically relates to a test radio frequency converter that avoids contact deformation. Background Technology

[0002] Radio frequency converters use modulation technology to convert audio and video baseband signals into high-frequency radio frequency signals, enabling them to be transmitted through coaxial cables and received by television devices with radio frequency input capabilities. This process involves signal amplification, mixing, and filtering.

[0003] like Figure 2 As shown, although the test RF converter relies on slotted contact heads for contact when the male and female are mated to achieve good intermodulation performance, the slotted contact heads are prone to deformation or even damage under repeated use, leading to electrical contact failure of the test RF converter. To address this, we propose a test RF converter that avoids contact deformation. Utility Model Content

[0004] The purpose of this invention is to provide a test RF converter that avoids contact deformation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a test radio frequency converter that avoids contact deformation, comprising: RF converter housing; A fixed insulator is provided inside the RF converter housing, through which a socket cylinder is provided; A slotted contact head, wherein the slotted contact head is disposed inside the plug-in terminal on the housing of the radio frequency converter; A stabilizing insulator is disposed between the insertion cylinder and the slotted contact head.

[0006] Preferably, a first limiting step is provided inside the RF converter housing, the fixed insulator is disposed at the position of the first limiting step, and the socket cylinder is limited and disposed inside the RF converter housing by the fixed insulator.

[0007] Preferably, a second limiting step is provided inside the RF converter housing, the slotted contact head is located at the position of the second limiting step, and the fixed insulator and the slotted contact head are connected in a limiting manner.

[0008] Preferably, the slotted contact head has a limiting slot, and the slotted contact head is limited and locked to the inside of the plug terminal on the RF converter housing through the limiting slot.

[0009] Preferably, the first limiting step and the second limiting step form a continuous step structure.

[0010] Preferably, the slotted contact head is an elastic metal component. Compared with the prior art, the beneficial effects of this utility model are: This invention incorporates a stable insulator between the socket cylinder and the slotted contact head. When testing the mating of male and female RF converters, after the slotted contact head and socket cylinder are installed in place, the stable insulator provides effective support for both the socket cylinder and the slotted contact head. This prevents the slotted contact head from deforming due to radial pressure, significantly improving the stability and durability of the RF converter during use. Attached Figure Description
