V. Description of the Invention (l) Technical Field of the Invention The present invention relates to an electrical connector, particularly a circuit board connector. μ θ a soft electric prior art

Please refer to FIG. 3, the conventional flexible circuit board connector is used to pull out the pressing element 20 and lift up, so that the flexible circuit board 25 can be inserted into the connection slot 13 as shown in FIG. 4, When the pressing piece 21 of the pressing element 20 is further inserted into the connecting groove 13, the flexible circuit board 25 and the contact point 19 of the terminal 15 can be electrically connected. "Π: Refer to Figures 1 and 2, which are a kind of conventional soft theft," including a body 10, a plurality of terminals 15, and the base 10 in a f is divided into a plurality by a separator ii. Ends: two: 20 connecting grooves 13; the terminal 15 is provided with a leg portion 16, both sides; a spring arm 18, the leg portion 16 extends out of the seat body 10, and the arms i7 on both sides are surnamed 12 is pressed, the spring arm 18 is provided with a contact point protruding to the connection slot ^. The tightening element 20 is clamped on the base 10 on both sides, and it is provided with a protruding L = 21, the pressing piece The 21 series can be inserted into the connecting groove 13 of the base 10. The conventional design has the following disadvantages: 1. The flexible circuit board 25 is forced by the pressing element 20 for electrical connection, so its base 10 The two sides must be clamped with the tightening component 20. However, the size of the flexible circuit board connector is originally small. When the number of terminals is small or the spacing is smaller, the base 10 will be smaller. Therefore, two small components ( The base body 〇 and the pressing element 20) are engaged with each other and slide the pressing piece 2 丨 into the connection of the base body 10

Page 5 1222241 V. Description of the invention (2)-Slot 13 is very difficult and the precision is very poor, because the assembled product will have cumulative tolerances. "Assembly on two very small objects requires high precision , Otherwise it will cause poor assembly due to the cumulative tolerance of the two. 2 · Since the flexible circuit board 25 is inserted into the connecting groove 13 of the base body, there is no effect of scraping the oxide layer of the contact point 19 of the terminal, and the contact point 19 of the terminal is exposed because it is not covered. In the air, when not used for a period of time, an oxide layer will be generated, which will affect the stability of the electrical connection. '' The conventional design also has a flip-type design. The pressing element adopts the flip-clip method to achieve pressing or loosening of the flexible circuit board. Therefore, it is also a pivotal combination of the base and the pressing element. Therefore, there are also the disadvantages mentioned above. SUMMARY OF THE INVENTION The main object of the present invention is to provide a flexible circuit board connector, the plastic body of which is a single body, which allows the flexible circuit board to be zero-inserted and inserted and then positioned tightly, thereby achieving manufacturing simplicity and reducing production costs. μ Another object of the present invention is to provide a flexible circuit board connector which can prevent an oxide layer from being generated at a contact point of a terminal. In order to achieve the above-mentioned object, the present invention includes a single body, each side of which is provided with a set of joints, which are provided with a plurality of spacers arranged at equal intervals, and a plurality of terminal grooves and one A connecting slot having an insertion opening for insertion of a flexible circuit board, and a wall surface of the terminal slot is provided with a high surface and a low surface having a step difference inward from the insertion opening; a plurality of terminals, which are The terminal slot of the base body is provided with a leg portion, a first spring arm, and a second spring arm. A gap is formed between the first and second spring arms, and the first spring

The connection slot 3 has an insertion opening 3 4 for a flexible circuit board to be inserted. The lower wall surface of the terminal slot 33 is directed toward the insertion opening 34. A stepped surface 3 5 and a lowered surface 3 6 are provided therein; and a set of connecting portions 37 is provided on both sides of the other seat body. The set of connecting portions 37 is provided with a platform 38 and a center of the platform 38 is provided. -^ Block 39, an inclined guide surface 31 is provided on the outside of the block 39 to facilitate the fixing element 60 to be easily inserted. .- ·-

Page 7 1222241 V. Description of the invention (4) A plurality of terminals 40 are provided in the terminal slot 32 of the base 30, which is provided with a pin 41, a first spring arm 42, and a first A second spring arm 43 below the spring arm 42. A gap 44 is formed between the first and second spring arms 42, 43. The first spring arm 42 is provided with a protruding and inverted hook contact to the crack 44 4 5. By virtue of being electrically connected to an inserted flexible circuit board, the second spring arm 43 is elastically abutted against the high surface 35 of the terminal slot, and the leading end of the first and second spring arms 42 and 43 is formed with an introduction slope 46 ′ To facilitate the insertion of flexible circuit boards.

The locking block 50 is provided with an inserting portion 51 and a holding portion 52 higher than the inserting portion 5. The inserting portion 51 is inserted into the connection groove of the base body, so that the contacts 44 with the plurality of terminals 40 It is urgent to position a plurality of terminals 40 on the base body 30. A recessed hole 53 is provided in the middle of the hand-held portion 51, so as to be inserted and dialed with a tool. Two fixing elements 60 are fitted on both sides of the base body. The socket part 37 is fixed on a circuit board, so that the seat body 30 can slide within the range where the fixing element 60 is engaged, and the cross section of the fixing element 60 is in the shape of [the top plate] 1 and the bottom plate 62, the center of the top plate 61 is provided with an opening 3 which is longer than the clamping block 39, and after being engaged with the socket portion 3 4 of the base body, the opening 6 3 is engaged with the clamping block 3 9 ' The clamping block 39 can be slid through the opening 63.

After the base body 30 and the plurality of terminals 40 are assembled, the present invention is first pressed tightly into the fixing block 50, so that the base body 30, the plurality of terminals 40, and the locking blocks are tightly closed, because The contacts 45 of the terminals have a protruding inverted hook design, so the locking block 50 can be easily pressed in but not easily removed. ^ Next, the operation of removing the locking block 50 will be described. Please refer to FIG. 8.
