Type-C connector and Type-C charging line

Abstract

According to the utility model, 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 utility model relates to Type-C joint technical field, concretely relates to Type-C joint and Type-C charging wire. BACKGROUND

[0002] Type-C joint includes the metal shielding shell of front and back longitudinal directions, is equipped with the joint body in the shielding shell, the shielding shell can provide shielding effect such as physical shielding, electromagnetic shielding for joint body, reduce the interference of outside environment to joint body.Joint body rear end exposes to the outside of shielding shell and is electrically connected with pcb board.Type-C charging wire includes the Type-C joint and electric wire, and the electric wire front end is electrically connected on pcb board and rear end connects power supply equipment, and joint body front end connects the power taking equipment that needs to charge, and power supply equipment charges power taking equipment via Type-C charging wire.Shielding shell rear is equipped with insulating protective shell and is protected to the pcb board and each electric connection place.In order to improve the structural firmness of Type-C joint in the process of pulling and inserting, shielding shell and protective shell are usually connected together.At present, the method is that shielding shell rear end is directly embedded into the inside of protective shell, and the connection is realized by using protective shell to wrap shielding shell rear end, in this case, the protective shell is necessarily wider than shielding shell, and it protrudes laterally outside shielding shell, and the protruding degree is roughly equal to the thickness of protective shell, and it cannot be made narrow laterally. SUMMARY

[0003] The utility model wants to solve the technical problem to provide a kind of Type-C joint, and the protective shell of its Type-C joint can be made narrow laterally.The utility model further provides a kind of Type-C charging wire, and the protective shell of its Type-C joint can be made narrow laterally.

[0004] The part of shielding shell rear end for connecting protective shell is called as connecting portion by inventor.In existing design, the cross-sectional shape of connecting portion is usually designed to be the same as shielding shell body, i.e. capsule shape in left-right direction, and the reason is that: connecting portion not only plays a connecting role, but also plays a protective effect to joint body rear end, so shape is designed to be capsule shape in left-right direction.This design leads to the part of protective shell corresponding to the narrow side of shielding shell rear end can only protrude to the outside of the narrow side of shielding shell rear end, so that protective shell is difficult to be made narrow laterally.

[0005] The inventor further studies and finds that the rear end of the connector body mainly concentrates on the wide side of the rear end of the shielding shell, that is, the narrow side of the rear end of the shielding shell does not actually bear important functions. Based on this discovery, the inventor proposes an innovative design: the connecting part is changed to extend from 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, thereby leaving a transverse gap on the narrow side of the rear end of the shielding shell. The corresponding narrow side of the protective shell is sunk into the transverse gap, and does not need to protrude to the outside of the narrow side of the rear end of the shielding shell as in the prior art, so that the transverse width of the protective shell is naturally smaller, and therefore the protective shell does not need to be designed to be wider than the shielding shell but can be transversely narrow, for example, can be designed to be transversely equal to the shielding shell or transversely narrower than the shielding shell, or designed to be transversely wider than the shielding shell but the transverse protrusion of the protective shell outside the shielding shell is less than the thickness of the protective shell.

[0006] To solve the above technical problems, the Type-C connector of the utility model, including front and rear longitudinal shielding shell, be equipped with connector body in shielding shell, shielding shell cross section is left and right transverse capsule shape, connector body rear end exposes to shielding shell outside to electrically connect external wire, shielding shell rear is equipped with the protective shell for protecting electric connection, shielding shell rear end extends and connects the protective shell in the connecting part, the connecting part specifically extends from 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, thereby leaving a transverse gap on the narrow side of the rear end of the shielding shell. The corresponding narrow side of the protective shell is sunk into the transverse gap.

[0007] Further, the protective shell is transversely equal to the shielding shell; or the protective shell is transversely narrower than the shielding shell; or the protective shell is transversely wider than the shielding shell but the transverse protrusion of the protective shell outside the shielding shell is less than the thickness of the protective shell.

[0008] Further, the connecting part has a transverse width of 7-7.8 mm, and the gap has a transverse width of 0.2-0.8 mm.

[0009] Further, the connecting part is transversely equal to the rear end of the connector body and only covers the rear end of the connector body.

[0010] Further, the utility model further comprises a pcb board for electrically connecting the external wire, the rear end of the connector body is electrically connected to the pcb board to indirectly electrically connect the external wire, and the protective shell wraps the pcb board and the electrically connected part thereon.

[0011] Further, the connecting part, the rear end of the connector body, and the pcb board are transversely equal and longitudinally aligned, and the connecting part only covers the rear end of the connector body.

[0012] The utility model discloses a Type-C charging line, which comprises a Type-C connector and a wire. The wire extends from the rear end of the Type-C connector into the protective shell of the Type-C connector to electrically connect the connector body. The Type-C connector is as described above.

[0013] Since the connecting portion does not cover the left end and / or the right end of the shielding shell but leaves a transverse gap on the narrow side of the rear end of the shielding shell, the corresponding narrow side of the protective shell does not protrude outside the narrow side of the rear end of the shielding shell as in the prior art but is transversely recessed into the gap, so that the transverse width of the protective shell is naturally smaller, i.e. the protective shell can be made transversely narrower, so that the protective shell does not need to be designed wider than the shielding shell but can be made transversely narrower, for example, can be designed transversely as wide as the shielding shell or transversely narrower than the shielding shell, or designed transversely wider than the shielding shell but with a transverse protrusion outside the shielding shell smaller than the thickness of the protective shell.

The Type-C connector 100 includes a front-to-back longitudinal metal shielding shell 2, and a connector body 1 is arranged in the shielding shell 2, the shielding shell 2 cross section is a left-to-right transverse capsule shape, the connector body 1 rear end 11 is exposed to the outside of the shielding shell 2 and is electrically connected with a pcb board 5, the pcb board 5 is transversely equal in width with the connector body 1 rear end 11 and is longitudinally aligned. 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 into the shell body interior, the protective shell 3 front part 31 wraps and protects the electrical connection part 51 of the pcb board 5 and the connector body 1, and also wraps and protects the connector body 1 rear end 11. The electric wire 200 front end 201 specifically extends forward from the Type-C connector 100 rear end into the protective shell 3 to electrically connect the pcb board 5 rear end, thereby indirectly electrically connecting the connector body 1, the protective shell 3 rear part 32 wraps and protects the electrical connection part 52 of the pcb board 5 rear end and the electric wire 200, and also wraps and protects the electric wire 200 front end 201. In use, the Type-C connector 100 connects the power taking device to be charged via the connector body 1, and the power supply device charges the power taking device via the electric wire 200, the pcb board 5 and the connector body 1 in sequence.

[0023] See Figure 2 , the upper and lower two connecting parts 215, 216 extend rearward from the upper and lower two wide sides 211, 212 of the shielding shell 2 rear end 21, the connecting parts 215, 216 are the same in transverse width with the connector body 1 rear end 11, both are 7-7.8mm (preferably 7.3mm), such as Figure 3 , only covering the connector body 1 rear end 11 without covering the shielding shell 2 left and right two ends 25, 26, thereby leaving left and right two transverse width 0.2-0.8mm transverse notches 213, 214 respectively in the left and right two narrow sides 217, 218 of the shielding shell 2 rear end 21. See Figure 4 , the connecting parts 215, 216 of the shielding shell 2 are embedded into the protective shell 3 rearward to connect the protective shell 3, the left and right front ends 311, 312 of the protective shell 3 shell body 35 correspond to the left and right two narrow sides 217, 218 of the shielding shell 2 rear end 21 respectively, and are transversely sunk into the left and right two notches 213, 214 of the shielding shell 2 rear end 21 respectively, without protruding to the outside of the narrow sides 217, 218 of the shielding shell 2 rear end 21 as in the prior art, so that the transverse width of the protective shell 3 is naturally smaller, that is, the transverse width of the protective shell 3 can be made narrower. See Figure 5, the protective shell 3 is transversely equal in width to the shielding shell 2, the protective shell 3 of other embodiments is Figure 6 , which is transversely narrower than the shielding shell 2, or is Figure 7 , which is transversely wider than the shielding shell 2 but has a transverse protrusion L1 outside the shielding shell 2 that is less than the thickness L2 of the shell 35 of the protective shell 3.

In a non-preferred embodiment, the connecting portions 215, 216 of the shielding shell 2, the rear end 11 of the joint body 1, and the pcb board 5 are not aligned, and the protective shell 3 needs to be transversely wide enough to cover all three.

[0024] A non-preferred embodiment is shown in Figure 3 , the connecting portions 215, 216 of the shielding shell 2 are changed to be transversely wider than the rear end 11 of the joint body 1, and the transverse gaps 213, 214 left on the narrow sides 217, 218 of the rear end 21 of the shielding shell 2 are relatively small. In order to ensure that the protective shell 3 is transversely equal in width to the shielding shell 2 as shown in Figure 5 , or is transversely narrower than the shielding shell 2 as shown in Figure 6 , or is transversely wider than the shielding shell 2 but has a transverse protrusion L1 outside the shielding shell 2 that is less than the thickness L2 of the shell 35 of the protective shell 3 as described in Figure 7 , a relatively thinner protective shell 3 needs to be used accordingly.

[0025] Another non-preferred embodiment is shown in Figure 3 , the connecting portions 215, 216 of the shielding shell 2 are changed to cover the right end 26 of the shielding shell 2 but not the left end 25 of the shielding shell 2, thereby leaving a transverse gap 213 on the left narrow side 217 of the rear end 21 of the shielding shell 2, and the left front end 311 of the protective shell 3 (see Figure 3 ) is transversely recessed into the gap 213. In order to ensure that the protective shell 3 is transversely equal in width to the shielding shell 2 as shown in Figure 5 , or is transversely narrower than the shielding shell 2 as shown in Figure 6 , or is transversely wider than the shielding shell 2 but has a transverse protrusion L1 outside the shielding shell 2 that is less than the thickness L2 of the shell 35 of the protective shell 3 as described in Figure 7 , a relatively thinner protective shell 3 needs to be used accordingly.
