New description: [New technical field] This creation is about the electrical connection of its terminals, especially the electrical connector used to connect a chip module on the circuit board and its use in the Terminal for electrical connector. [Prior Art] Referring to the first and second figures, a first embodiment discloses a conventional electrical connector terminal r, and the second figure discloses that the terminal is received in the terminal receiving hole 15'. situation. The terminal 丨 includes a ' 直 straight base 1G ′, an elastic arm 11 extending upward from the base, a domain portion 12 extending downward along the base ίο, and a pin 13 extending downward from the holding portion 12, The holding portion 12 is provided with inverted, thorn 120' on both sides, and the entire holding portion 12 has a flat shape. However, since the terminal holding portion 12 is flat and thin, and the terminal receiving hole 15 is limited by the punching technique, the X-direction read terminal is wide in the first direction, so that the terminal 丨 and the terminal receiving hole 15 are formed. A gap 14 is left in the front and rear positions in the X direction, and the gap 14 is easy to cause the terminal i to tilt when subjected to a force. Moreover, since the terminal receiving hole 15 is wide, it is difficult to hold all the terminal factories in a predetermined position of the terminal receiving hole 15 at the time of mounting, and the gap between the terminals r is likely to be unstable, which affects the electrical connection effect. . Based on the shortcomings of the prior art, there is indeed an improvement in the prior electrical connection and its terminals. [New content] The purpose is to provide an electrical connection 11 and its terminals, the terminals of which can be stably held in the electrical connector. The f-connection of the present invention is realized by the technical solution of the H-boat: the electric connection is crying, and the base comprises a base and a plurality of terminals accommodated in the base, the terminal comprises a base, a base, and an extension And a fixing portion extending from the other end of the base, the terminal extending from the two sides of the base to the base = the flat portion, the retaining portion including the bent portion extending from the base portion and The % fold further folds the extended interference. * The terminals are realized by the following technical solutions: a kind of terminal, which comprises a base and a base.

The positioning plate 7 is used for carrying the wafer. The module 8 is provided with a plurality of receiving holes 70 for receiving the number of the cymbals. The card body is provided with a plurality of card slots 7 opposite to the frame positioning groove 41. The plurality of limiting blocks 44 have a horizontal portion 441. And vertical from the horizontal 442 Γ ^ between the base support portion 221 and the buckle portion 223 to restrict the horizontal rotation of the rotating shaft 53 into the positioning groove 41 and the card slot 71 to assemble the frame 4 and the positioning plate 7 442 The step-by-step extension is formed—the corresponding structure on the recording base 2 is matched with the output σΜ43. The bottom plate of the base 2 is provided with a receiving plate 9 for receiving the terminal! The plurality of terminals are arranged at the relative positions of the standing plate 7 Hole 9 (). Among them, in the fourth figure, the micro-portion of the heart-shaped hole is divided into the hole, such as the test, not the implementation status of the Wei. The person is accommodated in the receiving plate 9 and is accommodated in the base 2, including in the vertical The direction is extended and the base of the shape is 卩(1), and the upper end of the wire portion 1G is upward. The end of the contact portion 11 is formed to be received in the receiving hole 7〇 of the positioning plate 7. The contact portion is similar. Having a width of (-) and a thickness, a tip 11a is formed at the end thereof, and the a is in contact with the conductive nucleus of the wafer when the electrical connection is reduced (4). The sides of the base of the two J 向 are outside the plane of the base Extending out of the holding portion 12, the holding portion 12 includes: ί°: the bent portion 121 extending from the test fold and the parallel portion being bent by the bent portion 121 The base portion 1 is located: further, the extending interference portion 122. The holding portion 12 is a non-flat plate type, and the upper portion of the holding portion 12 is generally an inverted triangle. The outer side of the holding portion 12 is provided with a guiding surface 123. (2) At the wire terminal 1, the predetermined position of the terminal receiving hole 9G can be guided. The two sides of the base 10 of the end 1 are close to the same direction f = at the holding portion 12, and the extending portion 10a can be prevented. When the terminal is placed in the receiving plate 9, the winding is opened. The fixing portion 13 is extended downward from the lower side, and the holding portion 131 is formed on the fixing portion 13 near the base 10 to the dog. The holding portion 131 is used to enhance the holding effect of the terminal 1 on the electrical connector. The free end of the fixing portion 13 is inserted into the circuit board to be in electrical contact with the conductive portion of the circuit board 7 M332971. The terminal receiving hole 90 of the threshing plate 9 includes a rear wall surface 9〇2, two side walls 9〇3, and a front wall surface 9〇1. The rear wall surface 902 is planar. The side wall 9〇3 is planar and has a width greater than the width of the base 10 of the terminal ι. The middle of the front wall surface 901 is recessed in a direction away from the rear wall surface. The miscellaneous terminal receiving hole 90 is easy to process and is not limited by the punching technique. The terminal i is from the top to the bottom of the female to the terminal receiving hole 90, and the guiding surface 123 of the terminal 雠 is directed to and in contact with the 雠9()3, and the terminal ι is guided to a predetermined position, so that the base 10 is in close contact with the terminal.
