After the lower shell and the upper shell are connected to the straight-extending shell, the cross-sectional area of ​​the tubular chamber formed by the second limiting part and the first limiting part is larger than the cross-sectional area of ​​the space enclosed by the second positioning part and the first positioning part; the first limiting member is connected to the hook, and the first positioning member is used to install the upper shell and the lower shell at a predetermined position of the straight-extending shell; the limiting members are respectively connected to the upper shell and the lower shell, and the limiting members are used to keep the straight-extending shell in a predetermined posture during the filling process.

[0008] By adopting the above technical solution, the straight-extending shell is firstly set on the predetermined position of the hook, and then the first positioning part and the second positioning part are installed on the predetermined position of the straight-extending shell as a whole through the first positioning member, and at the same time, the limiting member will keep the first limiting part and the second limiting part at the predetermined position, then the first positioning member and the limiting member will keep the upper shell, the lower shell and the straight-extending shell in a predetermined posture at all times, so that the straight-extending shell can maintain a predetermined posture during the glue filling process, thereby helping to improve the production yield rate of the TYPE-C male straight-extending connector.

[0009] Optionally, a first positioning notch and a second positioning notch are provided on two opposite sides of the straight extension shell; the first positioning portion is provided with a first positioning through hole, and the second positioning portion is provided with a second positioning through hole; the first positioning member includes a positioning protrusion, and two positioning protrusions are provided, one of the positioning protrusions is in the first positioning notch and the first positioning through hole, and the other positioning protrusion is inserted in the second positioning notch and the second positioning through hole.

[0010] By adopting the above technical scheme, due to the setting of the positioning protrusions, on the one hand, when the straight-extension shell is mounted on the hook, the two positioning protrusions are respectively inserted into the first positioning notch and the second positioning notch, so that the straight-extension shell can be installed at the predetermined position of the hook, thereby avoiding as much as possible the defect of low yield rate of the TYPE-C male straight-extension connector caused by misalignment of the straight-extension shell and the hook; on the other hand, when the lower shell and the upper shell are installed at the predetermined positions of the straight-extension shell, the two positioning protrusions will be respectively inserted into the first positioning through hole and the second positioning through hole, so that the upper shell and the lower shell can be installed at the predetermined positions of the straight-extension shell, thereby helping to improve the production yield rate of the TYPE-C male straight-extension connector.

[0011] Optionally, the first limiting portion is provided with a first limiting through hole at both connections between the upper shell and the lower shell, and the first limiting portion is provided with a limiting notch at both connections between the upper shell and the lower shell, and the notch direction of the limiting notch is close to the second limiting portion; the second limiting portion is provided with a second limiting through hole at both connections between the lower shell and the upper shell, and the second limiting through hole corresponds to the position of the first limiting through hole, and the second limiting portion is provided with a third limiting through hole at both connections between the lower shell and the upper shell, and the third limiting through hole is aligned with the limiting notch The position corresponds to that of the first limit block; the limit member includes a first limit block and a second limit block, the first limit block is made of elastic material, the first limit block is arranged on the inner wall of the first limit through hole, the first limit block extends in an arc shape toward a tubular chamber formed away from the first limit portion and the second limit portion, and the inner side of the bending of the first limit block is upward, the second limit block is arranged on the inner wall of the third limit through hole, the second limit block extends in an arc shape toward a tubular chamber formed close to the first limit portion and the second limit portion, and the inner side of the bending of the second limit block is downward.

[0012] By adopting the above technical scheme, on the one hand, due to the setting of the first limit block, and the first limit block extends in an arc away from the tubular chamber, and the inner side of the bend of the first limit block is upward, so when the first limit part is connected to the second limit part, the first limit block will be inserted in the second limit through hole, and the side of the first limit block away from the connection between itself and the first limit through hole will abut against the inner wall of the second limit through hole, so that the lower shell can be restricted from moving in the direction away from the upper shell; on the other hand, due to the setting of the second limit block, and the second limit block extends in an arc toward the tubular chamber, and the inner side of the bend of the second limit block is downward, so when the first limit part is connected to the second limit part, the second limit block will be inserted in the limiting notch, and the side of the second limit block away from the connection between itself and the third limiting through hole will abut against a side wall of the limiting notch away from its opening, so that the lower shell can be restricted from moving in the direction close to the upper shell, so that the upper shell and the lower shell can always be kept in the predetermined position.

[0013] Optionally, the first positioning portion and the second positioning portion are both provided with laser spot welding areas.

[0014] By adopting the above technical scheme, on the one hand, due to the setting of the laser spot welding area, after the upper shell and the lower shell are respectively installed at the predetermined positions of the straight-extending shell, the materials at the joints between the upper shell and the lower shell and the straight-extending shell are melted by laser heating for welding, thereby helping to improve the stability of the straight-extending shell during the filling process; on the other hand, compared with the method of using solder as a material for spot welding, this setting method does not need to set spot welding materials at the joints between the upper shell and the lower shell and the straight-extending shell, thereby making the structural form of the upper shell and the lower shell simpler.

[0015] Optionally, the first limiting zone and the second limiting zone are provided with a deformation groove, and the deformation groove is located in a portion of the first limiting zone or the second limiting zone close to the laser welding zone.

[0016] By adopting the above technical solution, since laser spot welding operation needs to be performed between the upper shell, the lower shell and the straight extension shell, the laser spot welding area of ​​the upper shell and the lower shell will be heated. According to the principle of thermal expansion and contraction, the deformation groove will provide a deformation part for the material of the first positioning part and the second positioning part, thereby reducing the overall deformation change of the upper shell and the lower shell.

[0017] Optionally, a second positioning member is further provided on the lower shell, the second positioning member is arranged in the tubular chamber, and the second positioning member is connected to the PCB board.

[0018] By adopting the above technical solution, since the positioning protrusion is not tightly fitted with the first positioning through hole and the second positioning through hole, the actual position of the entire straight extension shell may deviate from the predetermined position before laser spot welding. The provision of the second positioning piece can keep the entire straight extension shell in the predetermined position, thereby helping to improve the production yield of the TYPE-C male straight extension connector.

An adsorption through hole is arranged on the side of the bent inner side of the positioning plate away from the upper shell, and the adsorption through hole passes through the lower shell and is connected to an external air pump.

[0020] By adopting the above technical solution, since the positioning plate is U-shaped, when the lower shell is installed at the predetermined position on the straight extension shell, the PCB board on the hook will be inserted into the inner side of the bend of the positioning plate and abut against the inner side of the bend of the positioning plate. At the same time, the external air pump adsorbs the PCB board through the adsorption hole, which helps to improve the stability of the straight extension shell during the assembly process.

[0021] Optionally, four first limit through holes are provided, two first limit holes form a group, and two first limit holes in a group of first limit holes are respectively provided on the two ends of the same side of the lower shell; four first limit blocks are provided corresponding to the first limit through holes; the limiting notch is provided on the part between a group of the first limit through holes, and four second limit through holes are provided corresponding to the four first limit through holes.

[0022] By adopting the above technical solution, since four first limiting through holes, four second limiting through holes and four first limiting blocks are provided, and two first limiting through holes are provided in a group, and the two groups of first positioning through holes are provided on both sides of the extension direction of the lower shell, respectively, it is possible to simultaneously maintain a stable state at both sides of the two connection points between the upper shell and the lower shell during the filling process of the TYPE-C male straight-extension connector, thereby helping the upper shell and the lower shell to always maintain a stable state during the filling process, and further helping to improve the product yield of the TYPE-C male straight-extension connector.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Due to the arrangement of the first positioning member and the limiting member, when the TYPE-C male straight extension connector needs to be filled with glue, the straight extension shell is first set on the predetermined position of the hook, and then the second positioning portion of the lower shell is installed on the predetermined position of the straight extension shell as a whole through the first positioning member, and then the first positioning portion of the upper shell is installed on the predetermined position of the straight extension shell as a whole through the first positioning member. At the same time, the limiting member keeps the first limiting portion and the second limiting portion at the predetermined position, and the first positioning member makes the first positioning portion and the second positioning portion always abut against the straight extension shell, so that the straight extension shell maintains a predetermined posture during the filling process, thereby helping to improve the production yield rate of the TYPE-C male straight extension connector;

[0025] 2. Due to the setting of the positioning protrusions, on the one hand, when the straight extension shell is mounted on the hook, the two positioning protrusions are respectively inserted into the first positioning notch and the second positioning notch, so that the straight extension shell can be installed at the predetermined position of the hook, thereby minimizing the defect of low yield rate of TYPE-C male straight extension connector caused by misalignment of the straight extension shell and the hook; on the other hand, when the lower shell and the upper shell are installed at the predetermined positions of the straight extension shell, the two positioning protrusions are respectively inserted into the first positioning through hole and the second positioning through hole, so that the upper shell and the lower shell can be installed at the predetermined positions of the straight extension shell, thereby helping to improve the production yield rate of TYPE-C male straight extension connector;
