Embodiment
Refer to Fig. 2.Fig. 2 shows the electric connector of one first preferred embodiment of the application, the schematic diagram under the back of the body is placed on opening.The electric connector of the application can be, such as, and USB C type (USB typeC) connector.In fig. 2, the electric connector 200 of the application comprises connector body B, in order to be installed to (not shown) on a printed circuit board (PCB).Connector body B comprises a metal shell (B10, B11, B12) and an insulating body H, wherein metal shell (B10, B11, B12) coated insulation body H carrys out other electric connector accommodating to form a docking space, is electrically connected to be formed with other electric connectors.About the detailed construction of the insulating body H of Fig. 2, be shown in Fig. 1, do not repeated at this.It is noted that at this, element similar in this application or parts indicate with identical element numbers.
In this application, metal shell (B10, B11, B12) is an integrated metal housing (one-piece metal shell), have a upper cover B10, an a back of the body lid B11 and lower cover B12, wherein upper cover B10 has an a front end B101 and rear end B102.Upper cover B10 is connected with lower cover B12 in a welding manner.Back of the body lid B11 also links into an integrated entity with upper cover B10 in a welding manner, and wherein back of the body lid B11 is connected to the front end B101 of upper cover B10, and fastens with the rear end B102 of upper cover B10 detachably.In the present embodiment, back of the body lid B11 has a pivotal position (pivot portion) 204 as shown in Figure 2, and it is arranged at the front side edge of back of the body lid B11 and is made up of multiple bonding jumper (metal strip).In the present embodiment, pivotal position 204 is connected to the back side edge of the front end B101 of upper cover B10 and makes back of the body lid B11 can with pivotal position 204 for axle and rotating up and down, make to carry on the back lid B11 whereby to switch between the state opened and closed, and back of the body lid B11 is fastened with the rear end B102 of upper cover B10 separably.In this case, because metal shell (B10, B11, B12) adopts the structure of cover-lifting type to design.In addition, the rear end of the upper surface of the insulating body H of electric connector 200 has a perforation G1.Make carrying out reflow soldering so that when connector body B is surface mounted to the program of printed circuit board (PCB) whereby, facilitate thermal source by the mode of thermal convection by thermal diffusion to its front-seat weld part M11 of conductive metal terminals M1, and person easy to use observes the part-structure of part conductive metal terminals M1 via perforation G1.In addition, an inner surface of the side of back of the body lid B11 is provided with a hook (hook) 206A, and an outer surface of the side of the rear end B102 of upper cover B10 is provided with an end slot (terminal groove) 206B.After connector body B is surface mounted to printed circuit board (PCB), user only needs back of the body lid B11 to pressing down, hook 206A is meshed with end slot 206B, just the rear end B102 of back of the body lid B11 and upper cover B10 can be fastened, so that perforation G1 is closed, the schematic diagram of back of the body lid B11 under closed condition as shown in Figure 3.Therefore, via Machine Design so, back of the body lid B11 fastens with the rear end B102 of upper cover B10 separably, to close perforation G1 separably.
