The present application claims priority of Taiwan Patent Application No. 106143330, filed on Dec. 11, 2017, the entirety of which is incorporated by reference herein.
The invention relates to an electrical connecting assembly, and more particularly to an electrical connecting assembly having dust-proof and water-resistant properties.
The male and female connectors of a conventional electrical connecting assembly are not usually dust-proof or water-resistant. In particular, as the female connectors usually form a hole for receiving the male connectors, water and dust may easily enter the female connectors via the hole, whether in use or not, leading to safety problems such as short-circuiting or rust.
In recent years, the use of electrical connecting assemblies has become increasingly popular in the fields of precision mechanical equipment and medical instruments, and there is a demand for such mechanisms to be dust-proof and water-resistant. Hence, how to design an electrical connecting assembly with dust-proof and water-resistant properties has become a challenge.
In view of the aforementioned problems, one object of the disclosure is to provide an electrical connecting assembly that includes a male connector and a female connector corresponding to the male connector. The male connector has a first insulating body and a conductive member protruding from the insulating body. The female connector has a second insulating body, a hollow conductive seat, a resilient element, and sliding unit. The second insulating body forms an opening portion and a chamber for receiving the conductive member. The conductive seat is disposed in the chamber, the sliding unit is movably disposed in the conductive seat, and the resilient element connects the sliding unit to the conductive seat. Specifically, the internal diameter of the opening portion is shorter than the internal diameter of the conductive seat, and the resilient element provides an elastic force to move the sliding unit to the opening portion, so that the sliding unit forms a seal with the opening portion.
In some embodiments, the sliding unit has a slider and a flexible sealing ring disposed around the slider, and when the resilient element provides the elastic force to move the sliding unit to the opening portion, the sealing ring forms a seal with an inner surface of the opening portion.
In some embodiments, the slider has a flange abutting a side surface of the opening portion to restrict the sliding unit in the opening portion when the resilient element provides the elastic force to move the sliding unit to the opening portion.
In some embodiments, the slider and the sealing ring comprise an electrically insulating material.
In some embodiments, when the conductive member is inserted through the opening portion into the chamber, the conductive member pushes the sliding unit toward the inside of the chamber and is in contact with an inner surface of the conductive seat.
In some embodiments, the sliding unit has a slider and a flexible sealing ring disposed around the slider, and when the conductive member is inserted through the opening portion into the chamber, the sealing ring forms a seal with the inner surface of the conductive seat.
In some embodiments, the first insulating body has a first end surface and a second end surface, and the second insulating body has a third end surface and a fourth end surface, wherein the conductive member extends from the first end to the second end, the opening portion is disposed on the third end surface, and the conductive seat is exposed to the fourth end surface, wherein the first end surface abuts the third surface when the male connector is joined to the female connector.
In some embodiments, a part of the conductive member forms a banana connector terminal.
In some embodiments, wherein the resilient element comprises a compression spring.
In some embodiments, wherein the first and second insulating bodies have a cylindrical structure.
Another object of the disclosure is to provide an electrical connecting assembly that includes a male connector and a female connector corresponding to the male connector. The male connector has a first insulating body and a conductive member protruding from the insulating body. The female connector has a second insulating body, a hollow conductive seat, a resilient element, and sliding unit. The second insulating body forms an opening portion and a chamber for receiving the conductive member. The conductive seat is disposed in the chamber, the sliding unit is movably disposed in the conductive seat, and the resilient element connects the sliding unit to the conductive seat. Specifically, the sliding unit has a flexible sealing ring, and when the resilient element provides an elastic force to move the sliding unit to the opening portion, the sealing ring forms a seal with the opening portion.
In some embodiments, the sliding unit further has a slider, and the sealing ring is disposed around the slider.
In some embodiments, the slider has a flange abutting a side surface of the opening portion to restrict the sliding unit in the opening portion when the resilient element provides the elastic force to move the sliding unit to the opening portion.
In some embodiments, the slider and the sealing ring comprise electrically insulating material.
In some embodiments, when the conductive member is inserted through the opening portion into the chamber, the conductive member pushes the sliding unit toward the inside of the chamber and is in contact with an inner surface of the conductive seat.
In some embodiments, the sliding unit further has a slider, and the sealing ring is disposed around the slider, wherein when the conductive member is inserted through the opening portion into the chamber, the sealing ring forms a seal with the inner surface of the conductive seat.
In some embodiments, the first insulating body has a first end surface and a second end surface, and the second insulating body has a third end surface and a fourth end surface, wherein the conductive member is extended from the first end to the second end, the opening portion is disposed on the third end surface, and the conductive seat is exposed to the fourth end surface, wherein the first end surface abuts the third surface when the male connector is joined to the female connector.
In some embodiments, a part of the conductive member forms a banana connector terminal.

It should be realized that the sliding unit M is slidably received in the conductive seat C, and the two ends of the resilient element S push against the sliding unit M and an inner surface on the bottom portion C1 of the conductive seat C, respectively. Therefore, when the conductive member 12 of the male connector 10 is inserted into the female connector 20 through the opening portion 22, the sliding unit M is pushed and slides toward the inside of the conductive seat C, and the resilient element S is in a compressed state. Additionally, when the conductive member 12 of the male connector 10 is pulled out and detached from the female connector 20, the resilient element S can provide an elastic force to the sliding unit M, so that the sliding unit M returns to an initial state as shown in

When the male and female connectors 10 and 20 are completely joined to each other (
In summary, an electrical connecting assembly is provided, comprising a male connector and a female connector corresponding to the male connector. By arranging a hollow conductive seat, a resilient element, and a sliding unit in the female connector, water and foreign objects can be prevented from entering the conductive seat C via an opening portion of the female connector. Specifically, the resilient element can provide an elastic force to the sliding unit, so that the sliding unit can move back into a position in the opening portion and form a seal with the opening portion. Hence, dust-proof and water-resistant functionality can be achieved no matter whether the female connector is in use or not, thereby facilitating convenience and safety of usage.
While the invention has been described by way of example and in terms of preferred embodiment, it should to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation to encompass all such modifications and similar arrangements.
