Description

Technical Field

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

[0002] The Type-C connector usually includes a metal shielding shell extending in the front-to-back direction, and the connector body is arranged inside the shielding shell. The shielding shell not only provides physical protection for the connector body, but also achieves shielding effects such as electromagnetic shielding and physical shielding, effectively reducing the interference of the external environment on the connector body. The rear end of the connector body extends to the outside of the shielding shell and is electrically connected to the PCB board. The Type-C connecting cable consists of the above-mentioned Type-C connector and wires, and the front end of the wires is electrically connected to the PCB board. When in use, the rear end of the wires is connected to the power supply device, and the front end of the connector body is connected to the power supply device. The power supply device supplies power to the power supply device through the Type-C connecting cable.

[0003] An insulating protective shell is provided behind the shielding shell to protect the PCB. 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 existing technology usually embeds the rear end of the shielding shell directly into the protective shell, and achieves the connection by wrapping the rear end of the shielding shell with the protective shell. However, this structural design means that the protective shell must be wider than the shielding shell to accommodate the rear end of the shielding shell. Then, the protective shell will protrude laterally on the left and right sides of the rear end of the shielding shell. The degree of protrusion is roughly equal to the thickness of the protective shell, and it cannot be narrowed laterally. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a Type-C connector whose protective shell can be narrowed laterally. The present invention also provides a Type-C cable whose protective shell can be narrowed laterally.

[0005] The applicant defines the portion of the shielding shell's rear end that connects to the protective shell as the "connecting portion." The applicant previously proposed a new technical solution: the connecting portion is designed to extend only from the upper and lower wide sides of the shielding shell's rear end, leaving the left and right narrow sides of the shielding shell's rear end uncovered. This creates a transverse notch on the narrow side of the shielding shell's rear end. The portion of the protective shell corresponding to the narrow side fits within this notch, eliminating the need to protrude beyond the shielding shell as in the prior art. This allows the protective shell to be narrowed laterally, allowing it to be designed to be the same width as the shielding shell, narrower than the shielding shell, or still wider than the shielding shell but protruding less than the thickness of the protective shell.

[0006] The applicant applied for a patent (application number: 2025104474804, 2025206823449) with this technical solution as the preferred embodiment, and then carried out trial production according to the new technical solution. During the trial production process, a new technical problem arose: because the connection part in the new solution only extends from the upper and lower wide sides of the rear end of the shielding shell, the overall strength is poor and it is easy to deform under the action of external force. Among the series of adverse consequences caused by this, the most notable is the poor contact or even disconnection at the connection between the connector body and the PCB board. The reason is:

[0007] Generally, welding is not used for connection here, but "pin type" or "molding type" is used. These two connection methods are easy to assemble, but they are prone to loosening or displacement under the action of external force, which can lead to poor contact or even disconnection. When making a protective shell, the outer shell of the protective shell is usually put on the outside of the PCB board, and then insulating glue is injected into the inner side of the shell by injection molding to form an inner insulating layer. In order to prevent the insulating glue from being affected by the injection pressure during the injection molding process and rushing from the gap between the connecting part of the shielding shell and the PCB board to the connection between the connector body and the PCB board, UV glue is generally injected in the gap for sealing. Since there is inevitably a gap between the UV glue and the connecting part, the insulating glue may still penetrate into the gap under the action of the injection pressure and exert an outward force on the connecting part. If the connecting part is a complete structure (such as an elliptical shape), its overall strength is higher and it is not easy to deform. However, since the connection part in the new solution only extends from the upper and lower sides of the rear end of the shielding shell body, the overall strength is poor and it is easy to warp outward under the influence of outward force, exposing the connection between the connector body and the PCB board. Then the insulating glue will rush into the connection, which may eventually cause poor contact or even disconnection of the connection.

[0008] In order to solve the above technical problems, the Type-C connector of the present invention includes a front-to-back longitudinal shielding shell, the cross-section of the shielding shell body is a left-to-right horizontal capsule, a connector body is provided in the shielding shell body, the rear end of the connector body is exposed rearwardly outside the shielding shell body, and is used to electrically connect to external wires, and a protective shell is provided behind the shielding shell to protect the electrical connection, a connecting portion extends from the rear end of the shielding shell body and is embedded in the protective shell, the connecting portion specifically extends backward from the wide side of the rear end of the shielding shell body, does not cover the narrow side of the rear end of the shielding shell, and leaves a horizontal notch on the narrow side of the rear end of the shielding shell, and the portion of the protective shell corresponding to the narrow side is immersed in the notch; the shielding shell is provided with a reinforcing portion between the horizontal notch and the connecting portion, which is connected to the connecting portion to strengthen the connecting portion.

[0009] Furthermore, the reinforcement portion specifically extends rearward from the rear end of the shielding shell body.

[0010] Furthermore, the shielding shell body is transversely narrowed at a narrow side of the rear end, and the reinforcement portion specifically extends rearward from the narrowed portion.

[0011] Furthermore, rear ends of the reinforcing portion and the connecting portion are flush with each other.

[0012] Furthermore, the connecting parts are provided with an upper part and a lower part, respectively extending from the upper and lower wide sides of the shielding shell, and the reinforcing part connects the upper and lower connecting parts together.

[0013] Furthermore, the connecting portion does not cover the left and right narrow sides of the rear end of the shielding shell, thereby leaving left and right transverse gaps on the left and right narrow sides of the rear end of the shielding shell respectively. There are two left and right reinforcing portions respectively, which are located between the left transverse gap and the connecting portion and between the right transverse gap and the connecting portion respectively. The left reinforcing portion connects the left edges of the upper and lower connecting portions together, and the right reinforcing portion connects the right edges of the upper and lower connecting portions together.

[0014] Furthermore, the upper and lower connecting parts and the left and right reinforcing parts together form a left and right transverse capsule-shaped structure, and the transverse width of the capsule-shaped structure is smaller than that of the shielding shell body.

[0015] Furthermore, the rear end of the connector body is electrically connected to a PCB board, which is electrically connected to external wires via the PCB board, and the protective shell is wrapped around the outside of the PCB board.

[0016] Furthermore, the protective shell includes an outer shell and an insulating glue injected into the inner side of the outer shell, and a sealing material is filled between the connecting portion and the PCB board to block the front side of the insulating glue.

[0017] The Type-C cable of the present invention includes a Type-C connector and a wire. The wire extends from the rear end of the Type-C connector to the front into the protective shell of the Type-C connector to electrically connect to the connector body. The Type-C connector is as described above.

[0018] The portion of the protective shell corresponding to the narrow side does not protrude beyond the narrow side of the rear end of the shielding shell as in the prior art. Instead, it recesses into the notch. This naturally reduces the lateral width of the protective shell, allowing it to be narrowed laterally. Because the shielding shell's reinforcement is connected to the connecting portion, it strengthens the connection and is less susceptible to deformation under external forces. The reinforcement is located between the transverse notch and the connecting portion, preventing the protective shell from entering the transverse notch and thus preventing the protective shell from being narrowed laterally.

[0029] The present invention is further described in detail below in conjunction with specific embodiments.

[0030] Type-C cable see Figure 1 、 Figure 3The device comprises a Type-C connector 100 and a cable 200 extending longitudinally from front to back. The front end 201 of the cable 200 extends forward from the rear end of the Type-C connector 100 into the Type-C connector 100 to electrically connect to the Type-C connector 100, while the rear end 202 of the cable 200 connects to a power supply device (not shown). The front end of the Type-C connector 100 connects to a power supply device (not shown), which supplies power to the power supply device via the Type-C cable. The Type-C connector 100 comprises a metal shielding shell 1 extending longitudinally from front to back. The shielding shell 1 has a capsule-shaped cross-section extending transversely from side to side. A connector body 2 is located within the shielding shell 1. The rear end 21 of the connector body 2 protrudes rearwardly from the shielding shell 1 and is electrically connected to a printed circuit board 3. An insulating protective shell 4 protects the PCB 3. The protective shell 4 comprises an outer shell 41 and an insulating adhesive 42 injected into the shell 41. The protective shell 4 protects the rear end 21 of the connector body 2 and its electrical connection to the PCB 3, as well as the rear end 21 of the connector body 2. The front end 201 of the wire 200 extends forward from the rear end of the Type-C connector 100 into the protective shell 4, electrically connecting to the rear end of the PCB 3 and thus indirectly electrically connecting to the connector body 2. The protective shell 4 surrounds and protects the electrical connection between the rear end of the PCB 3 and the wire 200, and also surrounds and protects the front end 201 of the wire 200. During use, the Type-C connector 100 is connected to the power supply device via the connector body 2, and the power supply device charges the power supply device through the wire 200, the PCB 3, and the connector body 2.

[0031] See Figure 2 , from the upper and lower wide sides of the rear end of the shielding shell 1 body 10 (only the upper wide side 101 is shown in the figure due to the viewing angle), two upper and lower connecting parts 11 and 12 extend backward. The lateral width of the connecting parts 11 and 12 is 7 to 8 mm, which is wider than the rear end 21 of the connector body 2 but narrower than the shielding shell 1 body 10. Preferably, the lateral width of the connecting parts 11 and 12 is 7.3 mm, and the lateral width of the rear end 21 of the connector body 2 is 7.2 mm. The connecting parts 11 and 12 cover the rear end 21 of the connector body 2 but do not cover the left and right narrow sides 13 and 14 of the rear end of the shielding shell 1, thereby leaving left and right lateral gaps 15 and 16 with a lateral width of 0.1 to 0.8 mm on the left and right narrow sides 13 and 14 of the rear end of the shielding shell 1, respectively. See Figure 6The connecting parts 11 and 12 of the shielding shell 1 (not shown in the figure due to the viewing angle) are embedded in the protective shell 4 toward the rear to connect the protective shell 4. The left front end 411 and the right front end 412 of the shell 41 of the protective shell 4 correspond to the left and right narrow sides 13 and 14 of the rear end of the shielding shell 1, respectively, and are respectively sunk into the left and right notches 15 and 16 of the rear end of the shielding shell 1. There is no need to protrude to the outside of the narrow sides 13 and 14 of the rear end of the shielding shell 1 as in the prior art. In this way, the lateral width of the protective shell 4 is naturally made smaller, that is, the protective shell 4 can be made narrower laterally. The protective shell 4 is the same width as the shielding shell 1 in the lateral direction. See the protective shell 4 of other embodiments. Figure 8 , which is narrower than the shielding shell 1 in the transverse direction, or Figure 9 It is wider than the shielding shell 1 in the transverse direction, but its transverse protrusion L1 outside the shielding shell 1 is less than the thickness L2 of the shell 41 of the protective shell 4.

[0032] See Figure 4 and Figure 5 The narrow side 103 on the left of the rear end of the main body 10 of the shielding shell 1 is narrowed laterally to the right, and a first reinforcing portion 17 extends backward from the narrowed portion 105. The first reinforcing portion 17 connects the left edges 111 and 121 of the upper and lower connecting portions 11 and 12 together. The narrow side 104 on the right of the rear end of the main body 10 of the shielding shell 1 is narrowed laterally to the left, and a second reinforcing portion 18 extends backward from the narrowed portion 106. The second reinforcing portion 18 connects the right edges 112 and 122 of the upper and lower connecting portions 11 and 12 together. The first and second reinforcing portions 17 and 18 both have a reinforcing effect on the upper and lower connecting portions 11 and 12. The first reinforcing portion 17 is located between the left side transverse notch 15 and the connecting portions 11 and 12, and the second reinforcing portion 18 is located between the right side transverse notch 16 and the connecting portions 11 and 12. Neither of them will affect the protective shell 4 from sinking into the transverse notches 15 and 16, so it will not affect the protective shell 4 (see Figure 6 ) Make it narrow horizontally. Figure 3 The upper and lower connecting parts 11 and 12 and the first and second reinforcing parts 17 and 18 are flush with each other at the rear end, and together form a capsule-shaped structure 19 in the left and right directions. The capsule-shaped structure 19 has a width smaller than the shielding shell 1 body 10. Figure 7 UV glue 5 is filled between the capsule-shaped structure 19 and the PCB 3. The UV glue 5 acts as a sealing material, blocking the gap between the capsule-shaped structure 19 and the PCB 3 and blocking the front side of the insulating glue 42. This prevents the insulating glue 42 of the protective shell 4 from rushing through the gap under the injection pressure during the injection molding process to the connection between the rear end 21 of the connector body 2 and the PCB 3. However, due to the inevitable small gaps 6 between the UV glue 5 and the connection part (taking 11 as an example), the insulating glue 42 may still penetrate these gaps 6 under the action of the injection pressure and exert outward pressure on the connection part 11. Figure 3 、 Figure 7The first and second reinforcing portions 17 and 18 jointly reinforce the upper and lower connecting portions 11 and 12, so the connecting portion 11 is not easily warped outward under the pressure exerted by the insulating glue 42, and the connection between the rear end 21 of the connector body 2 and the PCB board 3 will not be exposed, so the insulating glue 42 will not rush to the connection.

[0033] See Figure 3 In this embodiment, the rear ends of the reinforcing parts 17 and 18 and the connecting parts 11 and 12 are flush, and the reinforcing effect is better. Figure 10 , the reinforcement parts 17 and 18 are shorter than the connecting parts 11 and 12, and the reinforcement effect is slightly weaker.

[0034] Non-preferred embodiments see Figure 6 The connecting parts 11 and 12 of the shielding shell 1 are changed to cover the right narrow side 14 of the rear end of the shielding shell 1 but not the left narrow side 13 of the rear end of the shielding shell, so that only the left narrow side 13 of the rear end of the shielding shell 1 is left with a transverse gap 15, and the left front end 411 of the shell 41 of the protective shell 4 is laterally immersed in the gap 15. Figure 6 As shown, it is the same width as the shielding shell 1, or as shown Figure 8 As shown, it is narrower than the shielding shell 1 in the transverse direction, or as shown Figure 9 The shielding shell 1 is wider in the transverse direction, but the transverse protrusion L1 outside the shielding shell 1 is smaller than the thickness L2 of the shell 41 of the protective shell 4, so a thinner protective shell 4 needs to be used accordingly.

[0035] The above is only an embodiment of the present invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the present invention and still fall within the scope of patent protection.
