A stabilizing component 40 'is provided. Both the first terminal 20 ′ and the second terminal 30 ′ are provided with solder feet for soldering on the electric circuit board, and the stabilizing part 40 ′ is provided with a positioning surface 41 ′ for soldering to the electric circuit board, 40 'allows the electronic card to be stably inserted on the electrical connector 100' without moving left and right.

  However, the known electric connector 100 ′ is an electric circuit so that the solder feet of the first terminal 20 ′ and the second terminal 30 ′ are not easily loosened by the peeling of the electric connector 100 ′ when the electronic card is inserted or removed. When soldering to the plate, the localization surface 41 ′ of the two stabilizing portions 40 ′ and the solder feet of the first terminal 20 ′ and the second terminal 30 ′ must be located on the same plane. It is relatively long and it is very difficult to position the bottom surface of the soldering feet of the localization surface 41 ′, the first terminal 20 ′, and the second terminal 30 ′ on the same horizontal plane. It is disadvantageous for cost reduction.

  An object of the present invention is to provide an electrical connector that can be easily soldered to an electric circuit board at a low production cost, in order to overcome the disadvantages existing in the known art.

  In order to achieve the above object, the electrical connector of the present invention includes an insulating body, a plurality of terminals, two fixing portions, and two stabilizing portions. The insulating body is provided with a plurality of terminal grooves, fitting support grooves are provided on both sides of the insulating body, extending arms are formed on both sides of the insulating body, and a fixing groove is provided on one end of the extending arm. The plurality of terminals are inserted into the terminal grooves of the insulating body, and the solder feet are positioned in a horizontal state on the bottom surface of the insulating body. The fixing portion includes a connecting portion, a soldering portion that bends and extends from one end of the connecting portion, and a hook-like support portion that bends and extends from the other end of the connecting portion, and the connecting portion is housed in a fixing groove, and It is possible to move in the vertical direction in the fixed groove, the hook-like support portion is hooked and supported by the extending arm, and the soldering portion is positioned in a horizontal state on the bottom surface of the insulating body. The stable portion is provided with a fitting joint, and the fitting joint is fitted into the fitting support groove of the insulating main body.

  As described above, since the connecting portion of the fixing portion of the electrical connector of the present invention can be moved in the vertical direction within the fixing groove, an appropriate error is allowed in manufacturing, and further, the soldering portion of the fixing portion and the solder of the terminal are allowed. Since the requirement to make the feet common is achieved, the manufacturing is relatively simple and the common surface is secured.

It is a three-dimensional view of the Example regarding the electrical connector of this invention. It is a three-dimensional exploded view of the Example regarding the electrical connector of this invention. It is a three-dimensional view of a known electrical connector.

  In order to detail the technical contents of the present invention, the structural features, and the objects and effects achieved by the present invention, the following description will be given in combination with the embodiments and drawings.

  As shown in FIG. 1, the electrical connector 100 of the present invention includes an insulating body 1, a first terminal 2, a second terminal 3, two fixing parts 4, and two stabilizing parts 5.

  As shown in FIG. 2, the insulating main body 1 is provided with a plurality of first terminal grooves 11 and a plurality of second terminal grooves 12. The first terminal grooves 11 are positioned below the front row, and the second terminal grooves 12. Is located on the upper side of the rear row, and the first terminal groove 11 and the second terminal groove 12 are combined to form the terminal groove described above, and fitting support grooves 14 are provided on both sides of the insulating body 1, respectively. The extending arm 13 that extends is formed, a protruding edge 131 that extends upward is formed at the left edge portion of the extending arm 13, and a fixing groove 132 is provided at the front end of the extending arm 13.

  The first terminal 2 is inserted into the first terminal groove 11 of the insulating main body 1, and the solder foot 21 is located on the bottom surface of the insulating main body 1 for soldering to the electric circuit board. The second terminal 3 is inserted into the second terminal groove 12 of the insulating main body 1, and the solder foot 31 is located on the bottom surface of the insulating main body 1 for soldering to the electric circuit board. For soldering to electrical circuit boards. The first terminal 2 and the second terminal 3 are combined to form the terminal.

  The two fixing portions 4 include a connecting portion 41, a soldering portion 42 that is bent and extended from one end of the connecting portion 41, and a hook-like support portion 43 that is bent and extended from the other end of the connecting portion 41. Is accommodated in the fixed groove 132 of the extending arm 13 and can be moved up and down in the fixed groove 132. The hook-like support portion 43 is hooked and supported on the end surface of the extending arm 13, and the soldering portion 42 is provided on the insulating body 1. It is located on the bottom of the board for soldering to the electric circuit board.

  A fitting joint 51 is provided at one end of the stabilizing portion 5, the fitting joining portion 51 is fitted in the fitting support groove 14 of the insulating body 1, and a fitting body 52 that is bent and extended at one edge portion of the stabilizing portion 5. The fitting body 52 presses the end face of the insulating body 1 and the lower edge of the stabilizing portion 5 contacts the protruding side 131 of the extending arm 13 in a pressed state.
