Description

Floating connector with status indicator lamp Technical Field The invention belongs to the technical field of connectors, and particularly relates to a floating connector with a status indicator lamp. Background Along with the continuous improvement of the diversified demands of the functions of the products in the connector industry, the products are increasingly urgent in demands for indicating the working state of the connector while integrating the current transmission function. LED lamps are commonly used in industry to indicate the working state of the product, such as circuit conduction and temperature state, particularly, if the fuse wire is fused inside the connector, whether the fuse wire is fused can be judged through the indicator lamp, and the product state can be identified visually by workers conveniently. The existing connector structure capable of indicating the working state of the connector is generally realized by the following 3 forms: 1. As shown in patent CN201601301U/CN101459301B, the product judges the working state of the product through a circuit on a built-in circuit board on the connector, and the exposed transparent light guide component is used for guiding out the signal of the LED lamp on the circuit inside the product to the outer surface of the product; 2. The transparent light guide component and the external light source are as shown in patent CN117117576A, a light guide column is arranged on the connector, and a light inlet end and a light outlet end are arranged on the light guide column, wherein the light inlet end is close to the bottom wall of the product, and the product transmits incident light close to the bottom wall to the light outlet end through the light inlet end. 3. Optical fiber-as shown in US20230204880A1, the connector members are connected optically. Light is transmitted from the input end to the output end by transmitting an optical signal through the flexible light pipe/optical fiber, and the input end can relatively move relative to the output end. In the related art, there are the following drawbacks: 1. The transparent light guide component and the built-in integrated LED circuit type are characterized in that an integrated circuit board and a light emitting element are arranged in each product, the manufacturing cost and the cost of the product are high, and due to the fact that the connector product is limited in size and a plurality of conductive components are added, the miniaturization of the product is limited, and the size is difficult to compress further. 2. The light input end needs to be close to a light emitting element outside the product, and a fixed base is needed to fix the input end, so that stable input of light is facilitated, and the connector cannot stably transmit an indication light signal when the I/O port of the product or the indication display interface needs to relatively move or float relative to the light emitting element inside the device. 3. Optical fiber type: the transmitting end of the product needs a light path conversion component to be connected to the laser diode, the original application scene of the whole transmission light path is the field of light modules, and the process and manufacturing cost of the product are too high for the indication function only used for displaying the state of the product, so that the economical efficiency is required to be improved.
