Description

Technical Field

[0001] The invention relates to a connector with a protection mechanism, and in particular to a connector with a protection mechanism, which can be reused and can easily identify the conductive state. Background Art

[0002] Connectors are used for current transmission, especially when transmitting large currents. As the current increases, the power also increases, which leads to a temperature increase, that is, an overload phenomenon. When the temperature rises, it may cause damage to the circuit, or even cause a fire. Therefore, a fuse is connected in the circuit connection. Once the circuit overheats due to overload, the resistance in the fuse will melt, resulting in a circuit break to avoid subsequent accidents.

[0003] However, although the above-mentioned conventional fuse blowing mechanism can effectively avoid the hazard of fire by timely disconnecting the circuit, since the fuse has been blown, it cannot be used again before replacing the fuse. Moreover, since the fuse is embedded in the connector, it is not only difficult to replace, but also increases the trouble of use.

[0004] Therefore, the inventor has considered this and thought of the idea of ​​invention, and then designed it based on many years of experience, and after much discussion and trial sample testing, and many revisions and improvements, he launched the present invention. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a connector with a protection mechanism, which can be reused and whose conductive status can be easily identified, in view of the above-mentioned deficiencies in the prior art.

[0006] Technical features for solving the problem:

[0007] The connector with protection mechanism of the present invention includes a connector, wherein the connector has a first terminal, a second terminal and a protector, the first terminal or the second terminal serves as a positive or negative pole and is connected to the protector, an indicator light is provided between the first terminal and the second terminal, and the indicator light will light up when the connector is in a conductive state, a connector seat is provided outside the first terminal and the second terminal, and a connector sleeve is further formed outside the first terminal, the second terminal, the protector, the indicator light and the connector seat to insulate and hide the wiring, and the protector is actually wrapped in the connector sleeve, the connector can be connected to a mating connector, the mating connector has two mating ends that respectively mate with the first terminal and the second terminal, the protector is a self-resetting fuse, and the protector is in a conductive state under a preset state, when the connector and the mating connector are connected to conduct and an overload condition occurs, the protector will block the current from passing, thereby achieving an overload protection effect, and the protector can automatically restore to a conductive state when not in an overload state.

[0008] As a further improvement of the present invention, the connector is a male end connector.

[0009] As a further improvement of the present invention, the protector is packaged in a shell and then packaged in the connector sleeve.

[0010] As a further improvement of the present invention, the protector is nakedly packaged in the connector sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The first main effect of the present invention is that, since the protector is a resettable fuse, the protector can be restored to a conducting state when not overloaded, thereby avoiding the need to destroy the connector sleeve to manually replace the protector, thereby increasing convenience in use.

[0013] The second main function of the present invention is that the indicator light will light up when the connector is in a conductive state. When the connector needs to be connected to the mating connector for conductivity, the indicator light can be used for auxiliary lighting to help the user connect the connector to the mating connector in a poorly lit environment. It also allows the user to easily identify that the connector can currently be used for power supply. When the protector blocks the current or the connector is currently unable to conduct electricity, the indicator light will go out, and the user can quickly know that the connector is currently unable to be used for power supply.
