Description

Technical Field

[0001] The utility model relates to the technical field of couplers, in particular to a groove-type cavity of a coupler. Background Art

[0002] As an important circuit and system connection device, coupler is widely used in many fields. Its working principle is based on the transmission and conversion of signals between different circuits or systems, and realizes the coupled transmission of signals through the electrical-optical-electrical conversion process.

[0003] The current coupler mainly performs electrical-optical-electrical conversion inside the coupler, forming a closed shell inside the coupler. Usually, the conductive rod is isolated and encapsulated in the closed shell with a transparent insulator.

[0004] Since the conductive rod needs to be set in a sealed shell, and the internal depth of the sealed shell is certain, the internal resonant frequency is certain, and the width of the conductive rod adapted to the certain resonant frequency is limited. When the resonant frequency causes the conductive rod adapted to be thinner, the conductive rod will be deformed during operation, affecting normal signal transmission, and thus unable to work normally, affecting work efficiency. Utility Model Content

[0005] The utility model provides a groove-type cavity of a coupler to solve the problems raised in the background technology.

[0006] In order to solve the above problems, the present invention provides a groove-type cavity of a coupler, including a left baffle, a right baffle, a front baffle, a rear baffle, a support base plate and a top cover, wherein the left baffle and the right baffle are respectively fixedly connected to the two sides of the top of the support base plate; the front baffle and the rear baffle are both fixed to the top of the support base plate; the left baffle, the right baffle, the front baffle, the rear baffle and the support base plate form a complete cavity; the top of the support base plate and the bottom of the top cover are both provided with grooves; the top of the support base plate is provided with an open groove; the open groove and the groove are connected to each other; the top cover is clamped on the top of the left baffle and the front baffle.

[0007] Preferably, the surfaces of the left baffle, the right baffle and the front baffle are all provided with joint holes; the tops of the front baffle, the rear baffle and the bottom of the top cover are all provided with weight-reducing grooves.

[0008] Preferably: a weight-reducing cavity is provided at the top of the top cover and the bottom of the supporting base plate; connecting threaded holes are provided on the surfaces of the top cover, front baffle and rear baffle; a waterproof groove is provided at the top of the inner side of the left baffle, right baffle, front baffle and rear baffle.

[0009] The beneficial effects of adopting the above technical solution are:

[0010] A complete cavity is formed by the left baffle, right baffle, front baffle, rear baffle and supporting base, so that electrical signals are transmitted inside the cavity. For the cavity, its depth will directly affect the frequency of resonance, which in turn determines the width of the conductive rod. If the conductive rod is too wide or too narrow, it will affect the reflection coefficient of the electromagnetic waves inside the cavity. A groove is opened on the top of the supporting base to increase the depth, thereby changing the frequency of resonance so that it can adapt to a wider conductive rod, thereby avoiding deformation of the conductive rod, ensuring normal signal transmission, and thus being able to work normally and improving work efficiency.

[0017] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0018] In the description of this utility model, unless otherwise specified, "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, movable connections, or integral connections; they can refer to mechanical connections or electrical connections; and they can refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

For the cavity, its depth will directly affect the frequency of resonance, and then determine the width of the conductive rod. If the conductive rod is too wide or too narrow, it will affect the reflection coefficient of the electromagnetic wave inside the cavity. A groove 7 is opened on the top of the supporting base plate 5 to increase the depth and thus change the frequency of resonance so that it can adapt to a wider conductive rod, thereby avoiding deformation of the conductive rod, ensuring normal signal transmission, and thus being able to work normally, thereby improving work efficiency.
