Description

Connector with a locking member

Technical Field

The present disclosure relates to connectors, and particularly to a connector for inserting into an electronic device.

Background

With the progress of science and technology, the functionality and convenience of electronic devices are continuously improved and widely used by the public. Currently, electronic devices include electronic products such as tablet computers (tablets), cellular phones (cellular phones), Global Positioning Systems (GPS), Personal Digital Assistants (PDAs), palm-sized PCs (personal-computers), and information appliances (information applications). A Universal Serial Bus (USB) is a serial bus standard for electronic systems and external devices, and is used to connect different electronic devices for data transmission or charging. Currently, USB Type-C (USB-C) connectors have been developed to support the plug insertion and the reverse insertion, so as to facilitate the use of USB.

However, the general USB connector is completely exposed in the non-use state, which may cause the connector to deform under pressure, and dust or moisture may enter the connector to cause the contact to be contaminated, so that the connector cannot be operated normally. Because the contact inside the USB Type-C connector is denser, the USB Type-C connector is more easily damaged due to short circuit caused by dust or moisture. To avoid this, a dust cap can be provided to completely cover the connector, thereby preventing dust or moisture from entering the connector and damaging the connector. However, the additional fitting is inconvenient to use and easy to lose.

Therefore, it is one of the important issues to provide a connector that has dust-proof and water-proof functions when not in use without installing a dust-proof cover, so as to prevent the connector from being damaged and further improve the service life of the connector.

SUMMERY OF THE UTILITY MODEL

Detailed Description

A connector according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings, in which like elements are referred to by like reference numerals.

Referring to fig. 1A to 2B, fig. 1A is an external view of the connector of the present invention when the connector end piece is not exposed. FIG. 1B is a schematic external view of the connector shown in FIG. 1A with the fitting end pieces exposed. Fig. 2A is a schematic cross-sectional view of a first embodiment of the connector of the present invention, wherein the terminal end pieces are not exposed. Fig. 2B is a schematic cross-sectional view of a first embodiment of the connector of the present invention, with the fitting end pieces exposed. In the present embodiment, the connector 1 is adapted to be inserted into an electronic device (not shown). The connector 1 includes a plug unit 11, a housing unit 12, and a shielding unit 13. The plug unit 11 includes a base member 111, and a connector end piece 112 provided on one side of the base member 111, the connector end piece 112 being adapted to electrically connect the electronic device. The housing unit 12 is slidably disposed on the plug unit 11, and includes a housing body 121, a first opening O1 located on one side of the housing body 121, and a second opening O2 located on the other side of the housing body 121 opposite to the one side, and the base member 111 is disposed through the first opening O1. The shielding unit 13 is disposed on the housing unit 12 and includes a cap body 131 disposed on the case body 121. The housing unit 12 moves relative to the plug unit 11, and when the connector end piece 112 is not exposed to the housing body 121, the shielding unit 13 completely shields the second opening O2; when the connector end piece 112 is exposed from the housing body 121, the shielding unit 13 partially shields the second opening O2. In the embodiment, the cover body 131 has a notch C, through which the connector end piece 112 is exposed to the housing body 121. In particular, the electronic devices are not limited to mobile phones, desktop computers, notebook computers, tablet computers, satellite navigation devices, personal digital assistants, energy storage devices, and other information devices or household appliances, which are well known to those skilled in the art. In addition, although the connector is referred to as a USB type-C (USB-C) connector, the connector may be, for example, but not limited to, a USB-a connector, a USB-B connector, a micro USB connector, a mini USB connector, a lightning connector, or the like. Furthermore, although the shielding unit 13 includes only the cap body 131 (the cap body 131 includes the notch C) for illustration in the present embodiment, the shielding unit 13 may include other structures, which will be described in detail later. In addition, although the cover main body 131 in which the cut C is a straight line and is only cut (the cut C is only located at the center of the cover main body 131) is illustrated in fig. 1A as an example, the cut C may be, for example, but not limited to, U-shaped, wavy, or cut into two pieces (the cover main body 131 is separated into upper and lower pieces by cutting from the left side to the right side of the drawing in fig. 1A) from the cover main body 131; while fig. 2A to 2B are schematic cross-sectional views of the connector 1, such that the cover body 131 is divided into an upper piece and a lower piece by the cut C, the cover body 131 may be a single member (as shown in fig. 1A), but is not limited thereto.

Referring to fig. 2A to 2B again, in the present embodiment, the base member 111 has an outer peripheral surface 1111 and a flange portion 1112 extending from the outer peripheral surface 1111 in a direction away from the base member 111, and when the terminal member 112 is not exposed to the housing body 121, as shown in fig. 2A, the housing body 121 is away from the flange portion 1112; when the fitting end piece 112 is exposed to the case body 121, as shown in fig. 2B, the case body 121 approaches the flange portion 1112. Specifically, the flange portion 1112 restricts displacement of the housing unit 12. When the joint end piece 112 is exposed to the case body 121, the case body 121 approaches the flange portion 1112, and the flange portion 1112 restricts a displacement stroke of the case body 121 to the right in the drawing.

Referring to fig. 2A and 2B, in the present embodiment, the connector 1 further includes an elastic element 14 (not shown in fig. 1A and 1B), wherein the elastic element 14 is disposed between the shell body 121 and the flange portion 1112, and when the contact end piece 112 is exposed out of the shell body 121, the shell body 121 approaches the flange portion 1112, so that the elastic element 14 is deformed to have an elastic force. In detail, the elastic member 14 serves to restore the housing unit 12. When the connector 1 is in a use state (as shown in fig. 2B), the contact end piece 112 is exposed from the housing body 121 so that the contact end piece 112 can be electrically connected to the electronic device, and at this time, the housing body 121 approaches the flange portion 1112, so as to press the elastic element 14 to deform and have an elastic force. When the terminal 112 is separated from the electronic device (i.e. in the non-use state), the elastic restoring force of the elastic element 14 moves the housing body 121 to the left in the drawing, and returns to the state where the terminal 112 is not exposed to the housing body 121 and the shielding unit 13 completely shields the second opening O2 (as shown in fig. 2A), so as to prevent the terminal 112 from being exposed to dirt and moisture.

Referring to fig. 3A and 3B, fig. 3A is a schematic cross-sectional view of a second embodiment of the connector of the present invention, wherein the terminal end is not exposed. Fig. 3B is a schematic cross-sectional view of a second embodiment of the connector of the present invention, with the fitting end pieces exposed. In the embodiment, the housing unit 12a further includes a stop piece 1211 disposed on the housing body 121a and located at the first opening O1, and when the terminal piece 112 is not exposed from the housing body 121a, as shown in fig. 3A, the base piece 111 abuts against the stop piece 1211 opposite to the other side (the side away from the terminal piece 112) of the side; when the joint end 112 is exposed from the housing body 121a, as shown in fig. 3B, the other side of the base 111 is away from the stop 1211. In particular, the connector 1a is substantially the same in structure, elements, and function as the connector 1 of the foregoing first embodiment, except for a stopper structure for the housing unit 12 a. In detail, in the present embodiment, the stop 1211 of the housing unit 12a of the connector 1a is used for limiting the displacement of the housing unit 12 a. When the joint end piece 112 is not exposed from the casing body 121a, the stop 1211 of the casing body 121a abuts against the side of the base piece 111 away from the joint end piece 112, so as to limit the displacement stroke of the casing body 121a to the left of the drawing.

Referring to fig. 4A and 4B, fig. 4A is a schematic cross-sectional view of a third embodiment of the connector of the present invention, wherein the terminal end is not exposed. Fig. 4B is a schematic cross-sectional view of a third embodiment of the connector of the present invention, with the fitting end pieces exposed. In the present embodiment, the housing body 121b of the connector 1b has an inner peripheral surface 1212, and a limit stopper 1213b extending from the inner peripheral surface 1212 in a direction away from the housing body 121b, the base member 111b has an outer peripheral surface 1111, and a limit projection 1113b extending from the outer peripheral surface 1111 in a direction away from the base member 111b, and when the terminal piece 112 is not exposed to the housing body 121b, as shown in fig. 4A, the limit stopper 1213b and the limit projection 1113b approach each other; when the joint end 112 is exposed from the housing body 121B, as shown in fig. 4B, the limit stopper 1213B and the limit projection 1113B are away from each other. In particular, the connector 1b is substantially the same in structure, elements, and functions as the connectors 1, 1a of the aforementioned first and second embodiments, except for a stopper structure for the housing unit 12 b. In detail, in the present embodiment, the case body 121b of the housing unit 12b of the connector 1b has a limit stopper 1213b (disposed at the case body 121b adjacent to the first opening O1), the base member 111b has a limit projection 1113b (disposed at a side of the base member 111b away from the joint end piece 112), and the limit stopper 1213b and the limit projection 1113b are used to limit the displacement of the housing unit 12 b. When the joint end piece 112 is not exposed to the housing body 121b, the limit stopper 1213b of the housing body 121b and the limit projection 1113b of the base piece 111b approach each other, and the displacement stroke of the housing body 121b to the left in the drawing is limited.

Referring to fig. 4A and 4B again, in the embodiment, the connector 1B further includes an elastic element 14B, wherein the elastic element 14B is disposed between the limiting protrusion 1113B and the cover body 131, and when the connector end piece 112 is exposed from the shell body 121B, the limiting protrusion 1113B and the cover body 131 approach each other, so that the elastic element 14B deforms to have an elastic force. In detail, the elastic member 14b serves to restore the housing unit 12 b. When the connector 1B is in a use state (as shown in fig. 4B), the terminal member 112 is exposed from the housing body 121B to enable the terminal member 112 to be electrically connected to the electronic device, and at this time, the limiting protrusion 1113B of the base member 111B and the cover body 131 approach each other, so as to press the elastic member 14B to deform and have an elastic force. When the terminal 112 is separated from the electronic device (i.e. in the non-use state), the elastic restoring force of the elastic element 14b moves the housing body 121b to the left of the drawing, and returns to the state where the terminal 112 is not exposed to the housing body 121b and the shielding unit 13 completely shields the second opening O2 (as shown in fig. 4A), so as to prevent the terminal 112 from being exposed to dirt and moisture.

Referring to fig. 5A and 5B, fig. 5A is a schematic cross-sectional view of a fourth embodiment of the connector of the present invention, wherein the terminal end is not exposed. Fig. 5B is a schematic cross-sectional view of a fourth embodiment of the connector of the present invention, with the fitting end pieces exposed. In the present embodiment, the housing body 121c of the connector 1c has an inner peripheral surface 1212, and a limit stopper 1213c extending from the inner peripheral surface 1212 in a direction away from the housing body 121c, the base member 111c has an outer peripheral surface 1111, and a limit projection 1113c extending from the outer peripheral surface 1111 in a direction away from the base member 111c, and when the terminal piece 112 is not exposed to the housing body 121c, as shown in fig. 5A, the limit stopper 1213c and the limit projection 1113c are away from each other; when the connector end piece 112 is exposed from the housing body 121c, as shown in fig. 5B, the limit stopper 1213c and the limit projection 1113c approach each other. In particular, the connector 1c is substantially the same in structure, elements, and function as the connector 1b of the foregoing third embodiment, except for a stopper structure for the housing unit 12 c. In detail, in the present embodiment, the housing body 121c of the housing unit 12c of the connector 1c has a limit stopper 1213c (disposed at a position where the housing body 121c is away from the first opening O1), the base member 111c has a limit projection 1113c (disposed at a side of the base member 111c away from the connector end piece 112), and the limit stopper 1213c and the limit projection 1113c are used to limit the displacement of the housing unit 12 c. When the joint end piece 112 is exposed to the housing body 121c, the limit stopper 1213c of the housing body 121c and the limit projection 1113c of the base piece 111c approach each other, and the displacement stroke of the housing body 121c to the right in the drawing is limited.

Referring to fig. 5A and 5B, in the present embodiment, the connector 1c further includes an elastic element 14c, wherein the elastic element 14c is disposed between the limit stop 1213c and the limit protrusion 1113c, and when the connector end piece 112 is exposed to the housing body 121c, the limit stop 1213c and the limit protrusion 1113c approach each other, so that the elastic element 14c deforms to have an elastic force. In detail, the elastic member 14c serves to restore the housing unit 12 c. When the connector 1c is in a use state (as shown in fig. 5B), the terminal part 112 is exposed from the housing body 121c to enable the terminal part 112 to be electrically connected to the electronic device, and at this time, the limit stop 1213c of the housing body 121c and the limit protrusion 1113c of the base part 111c approach each other, so as to press the elastic part 14c to deform and have an elastic force. When the terminal 112 is separated from the electronic device (i.e. in the non-use state), the elastic restoring force of the elastic element 14c moves the housing body 121c to the left of the drawing plane, and restores to the state where the terminal 112 is not exposed to the housing body 121c and the shielding unit 13 completely shields the second opening O2 (as shown in fig. 5A), so as to prevent the terminal 112 from being exposed to dirt and moisture.

Referring to fig. 2A, fig. 4A and fig. 5A, although the elastic members 14, 14b and 14c are taken as springs in the first, third and fourth embodiments for illustration, the elastic members 14, 14b and 14c may be torsion springs, elastic sheets, organ-shaped structural elements, or other elements that can generate elastic force to restore the original shape after being deformed by external force, which is not limited in the present invention. In addition, the elastic members 14, 14b, 14c may include, but are not limited to, metal, rubber, or polymer materials having elasticity.

Referring to fig. 1A to 5B, in the first to fourth embodiments, the housing bodies 121, 121A, 121B and 121c define a receiving space P capable of receiving the connector end piece 112. The plug unit 11 may further include a cable 113 provided on the other side of the base members 111, 111b, 111c with respect to the side (i.e., the side remote from the connector end piece 112), the cable 113 being electrically connected to the connector end piece 112. When the joint end piece 112 is exposed from the housing bodies 121, 121a, 121b, 121c, the joint end piece 112 abuts against the cap body 131 to deform the cap body. In detail, since the cover body 131 has the notch C, when the connector end 112 abuts against the cover body 131 to deform, the connector end 112 can pass through the notch C and be exposed out of the housing bodies 121, 121a, 121b, and 121C, and the deformed cover body 131 still does not exceed and is not exposed out of the second opening O2, so as to prevent the cover body 131 from affecting the matching of the connector end 112 and the electronic device when being connected. In particular, the variation of the incision C has been described in detail, and will not be repeated herein.

Referring to fig. 6A and 6B, fig. 6A and 6B are schematic views of different embodiments of a cover body of the novel connector. In the first to fourth embodiments, as shown in fig. 6A, the cover body 131 of the shielding unit 13 of the connectors 1, 1a, 1b, 1c and the shell bodies 121, 121a, 121b, 121c of the shell units 12, 12a, 12b, 12c may be independent components (made of different materials or the same material), the shell bodies 121, 121a, 121b, 121c have the inner peripheral surface 1212, and the cover body 131 is connected to the inner peripheral surface 1212 and is adjacent to the second opening O2; alternatively, as shown in fig. 6B, the cover body 131 and the housing bodies 121, 121a, 121B, and 121c of the shielding unit 13 may be integrally formed as a single component made of the same material. In the first to fourth embodiments, the material of the housing bodies 121, 121a, 121b, 121c includes, but is not limited to, silicone, rubber, or plastic material; the material of the cover body 131 includes, but is not limited to, silicone or rubber, or other deformable materials, and is not limited thereto.

Referring to fig. 7A to 7C, fig. 7A to 7C are schematic views illustrating different embodiments of a sealing sheet of the connector of the present invention. In the first to fourth embodiments, the shielding unit 13 may be replaced with a shielding unit 13 ', the cover body 131 ' of the shielding unit 13 ' may include the third opening O3, the shielding unit 13 ' may further include a sealing sheet 132, the sealing sheet 132 is disposed on the cover body 131 ' and selectively covers the third opening O3, and when the connector end piece 112 is not exposed to the shell bodies 121, 121a, 121b, and 121c, the sealing sheet 132 covers the third opening O3; when the connector end piece 112 is exposed to the housing bodies 121, 121a, 121b, 121c, the sealing sheet 132 does not shield the third opening O3. In the present embodiment, the third opening O3 has an inner periphery (as shown in fig. 7A to 7C, the boundary between the cap body 131' and the sealing sheet 132), the sealing sheet 132 is connected to the inner periphery, and the material of the sealing sheet 132 includes, for example, but not limited to, silicone or rubber. For example, the upper edge of the sealing sheet 132 is fixedly connected to the inner periphery of the third opening O3, but both side edges and the lower edge of the sealing sheet 132 are not connected to the inner periphery of the third opening O3 (the connection point is shown by the dotted line in fig. 7A to 7C), when the connector end piece 112 is exposed out of the shell body 121, 121a, 121b, 121C, the connector end piece 112 pushes against the sealing sheet 132 to deform (lift outwards) without shielding the third opening O3; alternatively, one side edge of the sealing sheet 132 is fixedly connected to the inner periphery of the third opening O3, but the other side edge, the upper edge and the lower edge of the sealing sheet 132 are not connected to the inner periphery of the third opening O3, when the connector end piece 112 is exposed to the shell bodies 121, 121a, 121b and 121c, the connector end piece 112 abuts against the sealing sheet 132 to deform (lift outward) the sealing sheet 132, so that the connector end piece 112 penetrates through the third opening O3, and the sealing sheet 132 does not shield the third opening O3. As shown in fig. 7A, the sealing sheet 132 and the cap body 131' may be independent components (made of different materials or the same material); alternatively, as shown in fig. 7B, the sealing sheet 132 and the cap body 131' may be an integrally formed single component made of the same material; alternatively, as shown in fig. 7C, the sealing sheet 132, the cap body 131' and the case bodies 121, 121a, 121b, and 121C may be integrally molded as a single component made of the same material.

In summary, the novel connector has the shielding unit, the shielding unit is arranged on the shell unit, and the shell unit moves relative to the plug unit, so that the plug unit of the connector can be shielded in a non-use state, the connector has the dustproof and water-splashing-proof functions, the plug unit is prevented from being stained, and the service life of the connector is prolonged.

The foregoing is by way of example only, and not limiting. It is intended that all equivalent modifications or variations not departing from the spirit and scope of the present invention shall be included in the appended claims.
