Type-C connector and Type-C charging line

Abstract

According to the invention, the Type-C connector and the Type-C charging line are protected. The connector comprises a shielding shell, a connector body is arranged in the shielding shell, the rear end of the connector body is backwards exposed out of the shielding shell, a protective shell is arranged behind the shielding shell, a connecting part extends out of the rear end of the shielding shell and is embedded into the protective shell to be connected with the protective shell, and the connecting part specifically extends out of the wide side of the rear end of the shielding shell and does not cover the left end and / or the right end of the shielding shell. Therefore, a transverse gap is reserved in the narrow side of the rear end of the shielding shell. The Type-C charging line comprises the joint and an electric wire, and the electric wire is electrically connected with the joint. As the transverse notch is reserved on the narrow side of the rear end of the shielding shell, and the part of the protective shell corresponding to the narrow side is transversely sunk into the notch, the transverse width of the protective shell is naturally small, namely, the protective shell can be transversely narrowed, so that the protective shell can be designed to be as wide as the shielding shell in the transverse direction or be narrower than the shielding shell in the transverse direction; the transverse protruding degree of the shielding shell outside the shielding shell is smaller than the thickness of the protection shell.

Description

Technical Field

[0001] The present invention relates to the technical field of Type-C connectors, and specifically relates to a Type-C connector and a Type-C charging cable. Background Art

[0002] The Type-C connector includes a metal shielding shell in the front-back longitudinal direction. Inside the shielding shell, there is a connector body. The shielding shell can provide shielding effects such as physical shielding and electromagnetic shielding for the connector body, reducing the interference of the external environment on the connector body. The rear end of the connector body extends out of the shielding shell and is electrically connected to a PCB board. The Type-C charging cable includes this Type-C connector and an electric wire. The front end of the electric wire is electrically connected to the PCB board and the rear end is connected to a power supply device. The front end of the connector body is connected to a power-taking device to be charged. The power supply device charges the power-taking device via the Type-C charging cable. Behind the shielding shell, there is an insulating protective shell that wraps the PCB board and each electrical connection part for protection. In order to improve the structural firmness of the Type-C connector during the plugging and unplugging process, it is usually necessary to connect the shielding shell and the protective shell together. The current method is to directly embed the rear end of the shielding shell into the interior of the protective shell, and use the protective shell to wrap the rear end of the shielding shell to achieve connection. In this case, the protective shell must be wider than the shielding shell, and it protrudes laterally outside the shielding shell, and the protruding degree is approximately equal to the thickness of the protective shell, and it cannot be made narrow laterally. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a Type-C connector whose protective shell can be made narrow laterally. The present invention also provides a Type-C charging cable whose protective shell of the Type-C connector can be made narrow laterally.

[0004] The inventor refers to the part of the rear end of the shielding shell for connecting the protective shell as the connecting part. In the existing design, the cross-sectional shape of the connecting part is usually designed to be the same as that of the shielding shell body, that is, a capsule shape in the left-right direction. The reason is that the connecting part not only plays a connecting role, but also plays a protective effect on the rear end of the connector body. Therefore, the shape is designed as a capsule shape in the left-right direction. This design causes the part of the protective shell corresponding to the narrow side of the rear end of the shielding shell to only protrude to the outside of the narrow side of the rear end of the shielding shell, resulting in difficulty in making the protective shell narrow laterally.

[0005] The inventor further studied and found that the rear end of the connector body is mainly concentrated on the wide side of the rear end of the shielding shell. That is to say, the narrow side of the rear end of the shielding shell actually does not carry important functions. Based on this discovery, the inventor proposed an innovative design: changing the connecting part to extend from the wide side of the rear end of the shielding shell, without covering the left end and / or the right end of the shielding shell, so as to leave a horizontal gap on the narrow side of the rear end of the shielding shell. The corresponding narrow side part of the protective shell sinks into the horizontal gap, without protruding to the outside of the narrow side of the rear end of the shielding shell as in the prior art. In this way, the horizontal width of the protective shell is naturally relatively small. Therefore, the protective shell does not need to be designed wider than the shielding shell, but can be made narrower horizontally. For example, it can be designed to be horizontally equal in width to the shielding shell or narrower than the shielding shell horizontally, or designed to be wider than the shielding shell horizontally but with its horizontal protrusion degree outside the shielding shell less than the thickness of the protective shell.

[0006] To solve the above technical problems, the Type-C connector of the present invention includes a longitudinally front-rear shielding shell, a connector body is arranged inside the shielding shell, the cross-section of the shielding shell is a horizontally left-right capsule shape, the rear end of the connector body extends backward out of the shielding shell to electrically connect to an external wire, a protective shell for protecting the electrical connection part is arranged behind the shielding shell, and a connecting part extends out from the rear end of the shielding shell and is embedded in the protective shell to connect the protective shell. Specifically, the connecting part extends from the wide side of the rear end of the shielding shell, without covering the left end and / or the right end of the shielding shell, so as to leave a horizontal gap on the narrow side of the rear end of the shielding shell, and the corresponding narrow side part of the protective shell horizontally sinks into this gap.

[0007] Furthermore, the protective shell is horizontally equal in width to the shielding shell; or the protective shell is narrower than the shielding shell horizontally; or the protective shell is wider than the shielding shell horizontally but with its horizontal protrusion degree outside the shielding shell less than the thickness of the protective shell.

[0008] Furthermore, the horizontal width of the connecting part is 7 - 7.8 mm, and the horizontal width of the gap is 0.2 - 0.8 mm.

[0009] Furthermore, the connecting part is horizontally equal in width to the rear end of the connector body and only covers the rear end of the connector body.

[0010] Furthermore, it includes a pcb board for electrically connecting to an external wire. The rear end of the connector body is electrically connected to the pcb board to indirectly electrically connect to the external wire, and the protective shell wraps and protects the pcb board and the electrical connection part thereon.

[0011] Furthermore, the connecting part, the rear end of the connector body, and the pcb board are horizontally equal in width and longitudinally aligned, and the connecting part only covers the rear end of the connector body.

[0012] The Type-C charging cable of the present invention includes a Type-C connector and a wire. The wire extends forward from the rear end of the Type-C connector into the protective shell of the Type-C connector to electrically connect to the connector body, and the Type-C connector is as described above.

[0013] Since the connecting part does not cover the left end and / or the right end of the shielding shell, but leaves a horizontal gap on the narrow side at the rear end of the shielding shell, the corresponding part of the narrow side of the protective shell does not protrude to the outside of the narrow side at the rear end of the shielding shell as in the prior art, but horizontally sinks into the gap. In this way, the horizontal width of the protective shell is naturally relatively small, that is, the protective shell can be made narrow horizontally. Therefore, the protective shell does not need to be designed wider than the shielding shell but can be made narrow horizontally. For example, it can be designed to have the same horizontal width as the shielding shell or be narrower than the shielding shell horizontally, or be designed to be wider than the shielding shell horizontally but the degree of its horizontal protrusion outside the shielding shell is less than the thickness of the protective shell.

Detailed Description of the Invention

[0021] The following further details the present invention in conjunction with specific embodiments.

[0022] The Type-C charging cable is shown in Figure 1 and Figure 2, including a Type-C connector 100 and a wire 200 longitudinally in the front and back. The front end 201 of the wire 200 extends forward from the back end of the Type-C connector 100 into the Type-C connector 100 for electrical connection, and the back end 202 is connected to a power supply device (not shown in the figure). The front end of the Type-C connector 100 is connected to a power-taking device to be charged (not shown in the figure). The power supply device charges the power-taking device via the Type-C charging cable. The Type-C connector 100 includes a metal shielding shell 2 longitudinally in the front and back. Inside the shielding shell 2, there is a connector body 1. The cross-section of the shielding shell 2 is in the shape of a capsule horizontally from left to right. The back end 11 of the connector body 1 extends backward out of the shielding shell 2 and is electrically connected to a pcb board 5. The pcb board 5 is horizontally as wide as and longitudinally aligned with the back end 11 of the connector body 1. An insulating protective shell 3 is wrapped outside the pcb board 5 to protect the pcb board 5. The protective shell 3 includes a shell body 35 and insulating glue 30 injected inside the shell. The front part 31 of the protective shell 3 wraps the electrical connection part 51 between the pcb board 5 and the connector body 1, and also wraps the back end 11 of the connector body 1. The front end 201 of the wire 200 specifically extends forward from the back end of the Type-C connector 100 into the protective shell 3 to be electrically connected to the back end of the pcb board 5, thereby indirectly electrically connecting to the connector body 1. The back part 32 of the protective shell 3 wraps the electrical connection part 52 between the back end of the pcb board 5 and the wire 200, and also wraps the front end 201 of the wire 200. When in use, the Type-C connector 100 is connected to a power-taking device to be charged via the connector body 1. The power supply device charges the power-taking device in sequence via the wire 200, the pcb board 5, and the connector body 1.

[0023] See Figure 2 , there are upper and lower connecting parts 215, 216 extending backward from the upper and lower wide sides 211, 212 of the back end 21 of the shielding shell 2. The connecting parts 215, 216 have the same horizontal width as the back end 11 of the connector body 1, both being 7 - 7.8 mm (preferably 7.3 mm), as Figure 3 , only covering the back end 11 of the connector body 1 without covering the left and right ends 25, 26 of the shielding shell 2, so that left and right horizontal gaps 213, 214 with a horizontal width of 0.2 - 0.8 mm are respectively left on the left and right narrow sides 217, 218 of the back end 21 of the shielding shell 2. See Figure 4 , the connecting parts 215, 216 of the shielding shell 2 are embedded backward into the protective shell 3 to connect to the protective shell 3. The left front end 311 and the right front end 312 of the shell body 35 of the protective shell 3 respectively correspond to the left and right narrow sides 217, 218 of the back end 21 of the shielding shell 2, and are respectively horizontally recessed into the left and right gaps 213, 214 of the back end 21 of the shielding shell 2, without protruding to the outside of the narrow sides 217, 218 of the back end 21 of the shielding shell 2 as in the prior art. In this way, the horizontal width of the protective shell 3 is naturally relatively small, that is, the protective shell 3 can be made narrow horizontally. See Figure 5, the protective case 3 has the same width as the shielding case 2 in the transverse direction. For the protective case 3 in other embodiments, see Figure 6 , which is narrower than the shielding case 2 in the transverse direction, or see Figure 7 , which is wider than the shielding case 2 in the transverse direction but the transverse protrusion degree L1 outside the shielding case 2 is less than the thickness L2 of the housing 35 of the protective case 3. In this embodiment, the connecting parts 215, 216 of the shielding case 2 are seen Figure 3 , which has the same width as the rear end 11 of the joint body 1 and the pcb board 5 in the transverse direction and is longitudinally aligned. As long as the protective case 3 (see Figure 2 ) can cover one of them in the transverse direction, it is sufficient to cover the other two at the same time. In a non-preferred embodiment, the connecting parts 215, 216 of the shielding case 2, the rear end 11 of the joint body 1, and the pcb board 5 are not aligned, and the protective case 3 needs to cover all three of them in the transverse direction.

[0024] For non-preferred embodiments, see Figure 3 , if the connecting parts 215, 216 of the shielding case 2 are changed to be wider than the rear end 11 of the joint body 1 in the transverse direction, then the transverse gaps 213, 214 left at the narrow sides 217, 218 at the rear end 21 of the shielding case 2 are relatively small. To ensure that the protective case 3 is as Figure 5 shown to have the same width as the shielding case 2 in the transverse direction, or as Figure 6 shown to be narrower than the shielding case 2 in the transverse direction, or as Figure 7 described to be wider than the shielding case 2 in the transverse direction but the transverse protrusion degree L1 outside the shielding case 2 is less than the thickness L2 of the housing 35 of the protective case 3, a relatively thinner protective case 3 needs to be used accordingly.

[0025] For another non-preferred embodiment, see Figure 3 , the connecting parts 215, 216 of the shielding case 2 are changed to cover the right end 26 of the shielding case 2 but not the left end 25 of the shielding case 2, so as to leave a transverse gap 213 at the left narrow side 217 at the rear end 21 of the shielding case 2. The left front end 311 of the protective case 3 (see Figure 3 ) is transversely recessed into this gap 213. To ensure that the protective case 3 is as Figure 5 shown to have the same width as the shielding case 2 in the transverse direction, or as Figure 6 shown to be narrower than the shielding case 2 in the transverse direction, or as Figure 7 described to be wider than the shielding case 2 in the transverse direction but the transverse protrusion degree L1 outside the shielding case 2 is less than the thickness L2 of the housing 35 of the protective case 3, a relatively thinner protective case 3 needs to be used accordingly.

[0026] As described above, this is only the implementation manner of the present invention, and the patent protection scope is not limited thereby. Those skilled in the art make non-substantive changes or substitutions based on the present invention, and still fall within the patent protection scope.
