Abstract

This invention relates to an electric connector. It comprises a base, and a plurality of terminals. The base has a plurality of terminal slots that installed in alternate arrangement. The multiple terminals dispose in the plurality of terminal slots of the base, where a fixing portion, a contact portion and a pin are installed. The fixing portion is clamped and positioned by the terminal slot. The contact portion connects with the top of the fixing portion. Wherein, the top is installed with a first elastic arm and a connection point. The pin is connected under the fixing portion and extends over the bottom of the base. The electric connector features a slanted parallelogram of the plurality of terminal slots. Namely, an included angle is formed by a vertical surface between two side surfaces and two edge surfaces of the terminal slot. Wherein, the fixing portion of the terminal leans against one edge surface of the terminal slot. While the first elastic arm of the contact portion extends slantingly against the terminal slot, it is clamped and positioned by the two side surfaces of the terminal slot. Therefore, when the terminal extends into a flat surface, the first elastic arm and the fixing portion will form the aforementioned included angle.

TECHNICAL FIELD OF THE INVENTION The invention relates to an electrical connector, and the term "four temples" refers to an electrical connector having an oblique groove structure. In the prior art, a plurality of connection gates arranged at intervals are formed on the bottom surface of a chip (such as a CPU). The electrical connector connected to the type of chip uses a pressure to place the chip on a body, so that the contacts of the chip and the The terminals arranged in the terminal slots of the base body are elastically contacted to ensure electrical connection.

1 is a kind of electrical connector for connecting chips. It is provided with two: a base body 10 on which a plurality of terminal slots u are arranged; and a plurality of terminals 14 which are provided on the base. The terminal slot u of the body is provided with a contact portion 15 capable of springing up and down. The contact portion 15 is provided with a spring arm 16 and a protruding contact point 17. When the wafer 90 is placed on the base 10, each contact 91 of the wafer 90 is in contact = contact 1 of each terminal 14: Please refer to FIG. 2, when the wafer 90 is pressed by force, 'each terminal 1 2 is contracted by the elasticity of the elastic arm 16, and at this time, the contact 丨 7 is elastically pressed against the contact 9 1 to achieve the electrical connection effect. The conventional structure has the following disadvantages: that is, the terminal grooves are rectangular and are arranged on the base body 10 at intervals. Please refer to FIG. 3. The terminals 14 are disposed in the terminal groove u. The longest effect is achieved (the length of the hypotenuse is longer than the length and width of the rectangle), so its flexibility has not reached the optimal state. Especially when the function of the CPU is getting stronger, its contacts are also increasing, so The base 10 needs to arrange more terminal slots 1 4 so that the terminal slots
