New description: [New technical field] Connections • Creation involves a kind of electrical connector, especially related to improving the structure of the terminal structure [Prior Art], Xi. Known for connecting a flexible printed circuit board, a flat cable, etc., the connection is generally an insulating body and a conductive terminal held in the insulating body, and the second member includes a driving member that presses the sheet-like connector. See U.S. Patent Publication No. 5,842,883, issued toK. The insulative housing is provided with a receiving space for receiving the chip-shaped connecting body and a terminal receiving groove communicating with the receiving space, wherein the terminal includes a contact extending in the terminal receiving groove and a pivoting arm extending substantially parallel to the contact arm. The pivot arm is provided with a pivoting portion that cooperates with the rotating plate. The portion of the head of the contact arm that is adjacent to the receiving space is raised above the plastic surface for better electrical contact with the sheet-like connector. Since the head of the terminal contact arm is substantially semi-circular, the above-mentioned electrical connector is not easy to be miniaturized in the case where the terminal has sufficient deformation space, the electrical connector has sufficient strength, and the sheet-like connector is easily inserted. With the development of technology, people have smaller and smaller requirements on the size of electrical connectors, so the above-mentioned terminals of the connector will be less and less able to meet the trend of increasingly miniaturized electrical connectors. See U.S. Patent Publication (10), No. 5, issued May 18, 1999, which discloses an electrical connector. The head of the electrical connector terminal contact arm is pointed at a sharp angle, so that the portion of the terminal head which is higher than the plastic surface is a sloped surface for facilitating the insertion of the sheet-like connector. However, the terminal is formed by stamping of a metal piece, and the terminal head is set to cause unstable pressing during pressing, and the hair is easily generated.夂 Therefore, it is indeed necessary to provide an electrical connector that overcomes the above drawbacks. [New content] Yes. The purpose of this creation is to provide an improved electrical connection technology for the terminal structure. To achieve the above objectives, the present electrical connector adopts the following 6 M307239: an electrical connector comprising an insulating body and being held on the insulative body. The insulative housing has a flat surface, and the flat surface is provided with a terminal receiving groove. The terminal has a contact arm extending along the terminal receiving groove, and the front end of the contact arm has a contact portion, and the contact The portion has a contact area on one side and protrudes beyond the terminal receiving groove, and a back surface on the other side and extending in the terminal receiving groove, the front end of the contact portion has a guiding slope and a circle connected to the guiding slope The arc surface, the distance from the center of the circular arc surface to the back surface is smaller than the radius of the circular arc surface. Compared with the prior art, the present invention has the following beneficial effects: since the distance from the center of the circular arc surface of the terminal contact portion of the present electrical connector to the back surface is smaller than the radius of the circular arc surface, the electrical connector is facilitated. The miniaturization is achieved, and the front end of the contact portion has a circular arc surface, and it is less likely to generate a hair during molding. [Embodiment] Referring to Figures 1 through 5, a first embodiment of the present electrical connector is shown. The electrical connector includes an insulating body 丨, a terminal 2 fixed on the insulating body, a rotating plate 3 assembled on the insulating body i, and a pair of grabbing members 4 mounted on the insulating body 1. The insulative housing 1 has a first side 1 11 , a second side wall 12 and a third wall 13 connected to the two side walls. A receiving space 10 is defined between the first side wall U and the second side wall 12, and the receiving space 10 has an opening defined as a direction perpendicular to the third wall 13 and directed to the first and second side walls u, 12. Extend the direction. The second (four) 12 has a flat surface 15A, and the flat surface 150 is exposed in the accommodating space 10, and the flat receiving surface 14 is provided with a terminal receiving groove 14 communicating with the receiving space 10. The first side iU is provided with a terminal receiving groove facing the terminal receiving groove 14 of the first side wall 12. Since the terminal receiving groove 14 is provided on the flat surface 150 of the second side wall 12, the flat surface 15 is divided into a plurality of elongated faces, and a groove wall 15 is formed between each two adjacent terminal receiving grooves 14. The groove wall 15 is chamfered at the opening of the receiving space to facilitate insertion with the docking connector. Both ends of the insulating body i are provided with a solid M307239 holding hole for holding the plate member 4! 6. Referring to the third and fourth figures, the terminal 2 includes a resilient contact extending along the side wall 12 and received in the terminal receiving groove 14. The terminal 2 is received in a relatively parallel manner and is received on the first side wall u. The arm 22, the connecting portion 20 connecting the two arms, and the welded portion 23 extending from the connecting portion 2〇=舁 contact #2 1 in the opposite direction. The second arm = is provided with a pivot #221. The front end of the contact arm 21 has a contact: ❿ As shown in the first to third figures, the rotating plate 3 has a straight portion on the side of the straight plate portion 30, and the comb portion is made of | A pivot portion 3 pivotally engaged with the pivot groove 221 of the terminal 2 is provided between the two ends of the comb portion. As shown in the third figure, the grasping plate member 4 has a holding arm 41 held in the holding hole 16 of the insulation: and a port holding ring 41 welded on the circuit board for supporting the end shaft 33, The rotating plate 3 is fixedly assembled on the insulative housing 1. ^ The rotating plate 3 can be rotated between an open state and a closed state, and the butt joint can be inserted when the rotating plate 3 is in an open state, and the docking connector is pressed when the rotating plate 3 is in a closed state. Electrically connected to the terminal. As shown in the fourth and fifth figures, the contact portion 2 ι of the terminal 2 is located on one side and protrudes from the contact area outside the terminal receiving groove 14 and the other side of the position and extends to the terminal receiving In the back surface 213 in the slot 14, the front end of the contact=210 has a guiding slope 211 and an arcing 212 connected to the guiding slope 2 ι. The center of the arcuate surface 2丨2 is formed to be smaller than the radius r of the arcuate surface 2丨2. As shown in the fifth figure, the face 212 is located below the flat face 15〇, and the guide bevel 211 is exposed above the flat face 15〇, and the butt joint can be easily inserted. The distance η between the center of the circular arc surface 212 and the back surface 213 is smaller than the radius R of the k-plane 212, which is equal to the distance between the center of the circular arc surface M307239 and the back surface applied in the prior art. The distance between the 213 and the bottom of the terminal receiving groove 14 is increased, thereby increasing the elastic deformation space of the contact portion 2丨〇, and reducing the possibility that the contact portion 210 abuts against the bottom of the terminal receiving groove 14 to damage the insulating body 1. With the development of technology, the size requirements for electrical connections are getting smaller and smaller. 'The circle is formed in the case where the terminal has sufficient deformation space, the electrical connector has sufficient strength, and the sheet-like connector is easily inserted. The distance h between the center of the curved surface 212 and the back surface 213 is smaller than the radius R of the circular arc surface 212, which contributes to miniaturization of the electrical connector. Since the contact portion 21 has an arcuate surface 212, it is less likely to generate a hair when the terminal 2 is formed into a thick shape. Soil: Referring to the sixth and seventh figures, it reveals two embodiments of the present invention. The difference from the first embodiment is that a portion of the curved surface 212 is exposed on the flat surface. The tangential line of the circular arc surface 212 which is exposed on the flat surface, 15 〇 卜 , and the perpendicular to the flat surface 15 〇 : : : 因此 因此 因此 因此 因此 因此 因此 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' Face 150 is hindered. Seeds: Fig. to Fig.; Fig. 10 shows the third two-third of the creation; the electrical connector disclosed by the embodiment and the above two ΐ = the arrangement of the contact portion 210 of the terminal 2. Further increasing the deformation space of the contact portion 210, that is, the distance between the two "face 213 and the bottom of the terminal receiving groove η, the center of the p-shaped melon surface 212 is located outside the contact of the back surface 213: 210" so the contact portion 21〇u: The miniaturization of the contact device is smaller. It is more advantageous for electrical connection. The plug-type chip connector of the above three embodiments, the in-line sheet shape is used for plugging in the plug type chip connection; The above three embodiments are similar in that the rotating plate 3 is connected to the non-open state and the closed state. When the plug member is in the open state, the M307239 can be connected in a chip form. The body is inserted into the connector and electrically connected to the terminal. The above three embodiments are connected to the electrical connector, and only need to be inserted with the docking connector.
