[Prior Art] The Republic of China New Patent Publication No. 揭示. discloses a power connector, a basin, an insulating body, a 1BJ-shaped medium terminal, a chip-shaped ground terminal, and a shielding case. The center terminal is inserted into the body of the lining body, and the card is attached to the circuit board. The grounding terminal is insulated from the body and connected to the circuit board by the === mouth end. ί £;=Surface welding === However, in actual use, the connector may not be able to be securely [out of the ΐ ΐ — 种 种 种 种 种 种 种 种 种 种 种 种 种 种 种 种 种 种 种 种 种 种 种 种The purpose of the invention is to provide an electrical connection 11 'which can be stably fixed to electricity for the above purpose. The present invention adopts an insulating body and is fixed to the insulating body. In the receiving cavity of the surface, the insulating body is provided with the holding legs and the pins on the same side of the body portion. The child is missing from the body portion to hold the foot. The solid tree is suspected: the present invention. The i connection is more stably mounted on the circuit board. [Embodiment] The shielding case 2: the center end is not provided. The electric connector 100 includes an insulative housing 1, a lost (four) die 4, and a ground terminal 5. In the second and fourth figures of the Yueyue Township, the insulative body 1 has a substantially rectangular parallelepiped shape and has - 6 200828700 for matching the electrical connection of the front end face 1G and the lining 11 of the collar end face. The insulative housing 1 is provided with a cylindrical receiving cavity through the front end surface 1 and a cylindrical fixing hole 12 penetrating the rear end surface 11 and communicating with the receiving cavity 101. The rear end surface n is surrounded by the fixing hole 12 The inner portion is recessed to form a stopper portion 13. The upper portion of the insulating body is opened from the rear end surface 11 in the direction of the front end surface 1G. The rear portion of the receiving surface i & the end surface 11 extends through the left and right sides of the insulating body 1 to divide the insulating body into upper and lower portions. The insulating body i extends horizontally from the top of the lower portion of the lower portion to the receiving portion 15. The projection 1 is provided with a projection W on the upper surface and both side surfaces of the front end face 10. The shielding housing 2 includes a main body panel 20, and two side plates 21 extending substantially perpendicularly to the main body panel 2''. The main body plate 20 is provided with a circular hole 2〇1, and the circular hole 2〇1 corresponds to the front end surface of the insulating body, the ^ valley receiving cavity 101, and the main body plate 20 extends vertically from the upper edge to the elastic piece, the elastic piece 202 and the two side plates 2 The latching portion 210 is disposed on the front end surface 10 of the insulative housing 1 by the latching portion 21 . The *' k-terminal 3 is a - column shape having a columnar contact 30 and a first interference portion 31, a second stem = 32, and a joint portion 33 which are arranged in this order from the columnar contact portion 3A. The first and second interference portions 3 and 32 are also cylindrical, and the cross-sectional areas thereof are larger than the cross-sectional area of the contact portion 30, and the cross-sectional areas of the three are sequentially reduced. As shown in Fig. 5, the fixing hole 12 is of a two-stage type, and the step portion 122 is formed. The center terminal 3 is assembled from the front end _ face 1 装入 into the insulative housing 丨, the first and second interference portions 31 and 32 are interference-fitted with the fixing hole 12, and the first interference portion 31 is blocked by the step portion 122, thereby preventing the center terminal 3 from being backward. Moving, the boss 121 provided in the fixing hole 12 can enhance the interference fit. The contact portion is located in the housing chamber 101, and the engaging portion 33 extends rearwardly out of the fixing hole 12. The fixing piece 4 includes a fixing portion 4A and a pin 41 having a gate structure which is bent downward from the fixing portion 40, and the fixing portion is shame-squared, has a matching hole 4〇1 in the middle, and has a tab on both sides. 4〇2. After the fixing hole 12 is assembled in the center terminal 3, the fixing portion 4 is inserted into the limiting portion 13, the engaging hole 4〇1 is engaged with the engaging portion 33, and the engaging portion 33 has a part of material extruded into the edge of the engaging hole 4〇1. In the notch 4〇3, the center & sub 3 can be prevented from rotating relative to the fixed piece 4, and the center terminal 3 can be further fixed. The tab 402 prevents the fixing piece 4 from rotating, thereby ensuring that the pin 41 is accurately soldered to the circuit board to form a complete circuit for the purpose of transmitting power. 7 200828700 Please refer to the third and fifth figures. The grounding terminal 5 is formed by sheet metal stamping, and includes a body portion 50, an elastic contact portion 弯 extending downward from the rear edge of the body portion 50, and two from the body portion 50. The retaining leg 52 and the pin 53 extending substantially vertically downward from the side and the protruding portion 54 extending horizontally from the front edge toward the cymbal. The body portion 50 is provided with a protruding piece that protrudes upward. The elastic contact portion 51 is bent near the front end face 1 to form a second contact portion 51A. The holding leg % is substantially parallel to the pin 53 and is located in front of the pin 53. The end of the holding leg 52 extends from two parallel hook-shaped retaining portions 520' and a slit is disposed between the two parallel retaining portions 52A. As shown in the second figure, the grounding terminal 5 is received in the receiving slot 14, and the holding leg 52 and the pin 53 extend from the left and right through portions of the rear of the receiving slot 14, and are supported by the receiving portion 15, and the protruding portion 54 extends into the receiving groove. 14 other parts, and then the grounding terminal 5 is held in the insulating body〗. As shown in the fifth figure, the protruding piece 501 abuts against the insulating body ,, and prevents the grounding terminal 5 from exiting from the insulating body 1. The second contact portion 510 is located in the receiving cavity 1〇1, and can be matched with the electric power. Connect to the crying network. In this embodiment, the electrical connector 100 is mounted on a circuit board. The circuit board (not shown) is generally provided with a notch. The electrical connector 100 is placed in the notch, and the lower surface of the receiving portion 15 stands on the circuit board. Within the gap, the well-known sinker type connector in the industry. The pin 53 of the electrical connector 10() is plugged onto the circuit board and soldered to the circuit on the circuit board. The pinch foot is passed through the corresponding hole of the circuit board and is fastened to the circuit board by the hook-shaped holding portion 52. The connector 100 is stably held on the circuit board.
