[0028] The present utility model provides a drawing and fully enclosed TYPE c connector. Please refer to Figures 1 to 8, the drawing and fully enclosed TYPE-C connector includes a connector body 10, the connector body 10 includes a housing assembly 1 and a terminal assembly 2 disposed within the housing assembly 1. The terminal assembly 2 is used to abut against an external device to achieve current or signal connection, and the housing assembly 1 is used to fix and protect the terminal assembly 2, improve the insertion strength of the terminal assembly 2, and facilitate the installation of the connector body 10 on an electronic device. Please refer to Figure 1 and Figure 2 , the housing assembly 1 includes a main housing 11, an upper housing 12 welded to the upper side of the main housing 11, and a lower housing 13 welded to the lower side of the main housing 11. The upper housing 12 and the lower housing 13 are used to facilitate the installation of the connector body 10 on an electronic device. Please refer to Figure 3 and Figure 4 , the main housing 11 includes an outer sleeve ring 111 formed by one-time stretching, a connecting wall 112, and an inner sleeve ring 113. The outer sleeve ring 111 has opposite front and rear ends. The connecting wall 112 is annular and its outer surface is connected to the inner side of the rear end of the outer sleeve ring 111. The inner sleeve ring 113 is connected to the inner side of the connecting wall 112 and extends from the rear end to the front end. The inner sleeve ring 113 sleeves the terminal assembly 2, playing a role in fixing and enhancing the strength of the terminal assembly 2. During use, an external device is inserted into the outer sleeve ring 111 and abuts against the terminal assembly 2 within the outer sleeve ring 111. The outer sleeve ring 111 of the main housing 11 is an integrally fully enclosed structure, which can effectively shield external signal interference, thereby improving the signal transmission and function smoothness of the product, and meeting the EMI (electromagnetic interference) requirements and the test standards of the European Union. Please refer to Figure 5 , the terminal assembly 2 has a tail 21 extending out from the rear end. The upper side of the rear end of the tail 21 has an avoidance structure 22 that reduces the thickness of the tail 21 in the rearward direction to reduce the volume of the connector body 10. In the present utility model, the main housing 11 is formed by one-time stretching, and the upper housing 12 and the lower housing 13 are respectively welded to both sides of the main housing 11 to obtain the housing assembly 1. The housing assembly 1 has a simple manufacturing process, low production cost, and better signal shielding function. Moreover, the tail 21 of the connector body 10 is provided with an avoidance structure 22, and the product has a small volume, which can well reserve installation space for other parts and avoid signal interference to the drawing and fully enclosed TYPE-C connector caused by other components being too close.

[0029] It can be understood that in order to reduce the volume of the TYPE-C connector, in the prior art, the terminals of the TYPE-C connector are often designed to be smaller, so that its cross-sectional area is also smaller, resulting in the current-carrying capacity of the TYPE-C connector in the prior art being limited, and further reducing the charging speed of the TYPE-C connector. However, in the present utility model, by designing the avoidance structure 22, the influence on the terminal design of the TYPE-C connector is avoided, thereby avoiding the problem of reducing the charging speed of the TYPE-C connector.

[0030] For the housing assembly 1, refer to Figure 5 , optionally, the upper shell 12 may include a main board 121 and side plates 122 respectively connected to both sides of the main board 121.

In practical applications, the center distance between the two first fixing holes 1221 can be 14.00 mm. The fastener can be a screw or a bolt, etc.

[0031] Preferably, an avoidance hole 123 that exposes the tail 21 and makes the upper shell 12 stepped may be provided near the rear end of the upper shell 12, so as to reduce the volume of the housing assembly 1. The design of the avoidance structure 22 and the avoidance hole 123 also creates a gap between the connector body 10 and the components inside the electronic device (such as a metal bracket, etc.), avoiding signal interference caused by other components being too close to the draw-all-inclusive TYPE c connector.

[0032] Preferably, the lower shell 13 may have a second docking member 131 facing the circuit board 20 of the electronic device and used for docking with the circuit board 20.

The fixing portion 271 is sleeved inside the inner collar 113 for fixation. The plugging and supporting portion 273 supports one end of the first terminal group 23, the second terminal group 24, and the spacer 25 and is exposed inside the outer collar 111, supporting one end of the first terminal group 23, the second terminal group 24, and the spacer 25, and also facilitating the external device to be plugged into the outer collar 111 and abut against the plugging and supporting portion 273 to improve the stability of the electrical connection.

[0036] Specifically, please further refer to Figure 5 , the avoidance structure 22 may be a step and / or an inclined surface provided on the surface of the protruding portion 272, so that there can be a relatively large reserved space at the upper end of the tail 21, and there can be sufficient reserved gaps between the connector body 10 and other components of the electronic device. Further, the maximum distance of the reserved gap (i.e., the distance between the uppermost end of the avoidance structure 22 and other components of the electronic device) can be greater than 0.3 mm.

[0037] Further, the steps can be provided on both sides of the protruding portion 272. The upper shell 12 extends with a first positioning member 124 that can be inserted into the steps. During installation, the first positioning member 124 can be inserted into the steps and abutted against the side surface of the upper step and the upper surface of the lower step to play a positioning role. Preferably, the first positioning member 124 can be in a plate shape, thereby effectively saving space.

[0038] Optionally, please refer to Figure 2 and Figure 5 , a positioning groove 2721 can be provided on the lower side of the protruding portion 272.
