Embodiment 1

[0024] Such as Figure 1 to Figure 5A low-loss coupler shown includes a coupler body 4 with three plugs, the coupler body 4 is square, and the three plugs are respectively a first plug 1, a second plug 2, and a third plug. The plug 3, the first plug 1, the second plug 2, and the third plug 3 are respectively located on one side surface of the coupler body 4, and the first plug 1 and the third plug 3 are respectively located on opposite sides of the coupler body 1, The distance between the second plug 2 and the first plug 1 is smaller than the distance between the second plug 2 and the third plug 3; it also includes a first end cover 5 and a second end cover 6, and the first end The cover 5 is made up of a first connecting block 51 and a second connecting block 52 which are at right angles to each other. The first connecting block 51 is provided with a first through hole 7, and the inner diameter of the first through hole 7 is larger than the inner diameter of the first through...

Embodiment 2

[0026] Such as Figure 1 to Figure 5 In the shown low-loss coupler, on the basis of Embodiment 1, the thickness of the first connection block 51 is greater than the length of the first plug 1; the thickness of the second connection block 52 is greater than the length of the second plug 2 length. The linear protrusion 11 is located on the first connecting block 51 , and the long axis of the linear protrusion 11 is perpendicular to the axis of the first through hole 7 . A rubber band 10 is also included, and both the first end cover 5 and the second end cover 6 are connected to the coupler body 4 through the rubber band 10 . A layer of sponge is laid on the inner walls of the first through hole 7 , the second through hole 9 and the U-shaped groove 8 .

Abstract

The invention discloses a low-loss coupler. A first end cap and a second end cap are adopted, a first plug, a second plug and a third plug are protected, complete covering is provided for each plug asa whole, each plug is wrapped from the top to the root, and thus the protection ability is remarkably improved. The first end cap and the second end cap form a mechanical structure directly connectedto a coupler body. If any of the plugs is hit by external force, the acting force can be quickly transmitted to the coupler body through the first end cap or the second end cap so as to be borne by the coupler body instead of being borne by the plug alone. In this case, the bearing capability of the plugs is significantly improved when the plugs are hit by external force, and risks of being bentor even damaged by the impact are significantly reduced. If the first end cap and the second end cap are not needed, the first end cap and the second end cap can be conveniently engaged so as to be prevented from being scattered around and being lost.

Description

technical field [0001] The invention relates to the field of couplers, in particular to a low-loss coupler. Background technique [0002] The optocoupler is an electrical-optical-electrical conversion device that transmits electrical signals through light as a medium. It consists of two parts: the light source and the light receiver. The light-emitting source and the light-receiving device are assembled in the same airtight casing, and they are separated by transparent insulators. The pin of the light source is the input end, and the pin of the light receiver is the output end. The common light source is a light-emitting diode, and the light receiver is a photodiode, phototransistor, etc. There are many types of optocouplers, such as photodiode type, phototransistor type, photoresistor type, light-controlled thyristor type, photoelectric Darlington type, integrated circuit type, etc. There are two types of couplers, metal shell package and plastic package. No matter which...
