Cooperate and to consult Fig. 8, these a plurality of terminals 60 are the strips 616 that fracture again behind a plurality of terminal grooves 41 of the whole row interior seat 40 that from top to bottom is assembled in this base, and it is provided with a fixed part 61, an elastic arm 62, an and pin portion 63; This fixed part 61 is with terminal groove 41 packings location and be provided with into the first folding plate 64 and second plate 65, this first plate 64 smooth in terminal groove 41 first wall 44 and use third and fourth wall 46,47 packings with this terminal groove near first clamping part 66 that the upper end is provided with plate face broad, the plate face of this second plate 65 punctures and stamps out second clamping part 67 that protrudes and use second wall, 45 packings with this terminal groove; This elastic arm 62 is connected in second plate, 65 upper ends of fixed part 61, it extends to second wall 45 earlier and turns round to the fixed part direction again and be from bottom to top diagonally extending, and its terminal 68 process first walls 44 are to next door terminal groove 41 tops, it is provided with the hypomere 69 and the narrower epimere 610 of plate face of plate face broad, this hypomere 69 is the curved arc shape and plate face central authorities are provided with a perforate 611, the end of the elastic arm epimere 610 of this each terminal correspond to up and down the terminal in the terminal groove of next door elastic arm hypomere 69 perforate 611 and can get out of the way mutually and do not contact, its epimere 610 is provided with a highest contact 612 near terminal 68 in addition, this contact 612 is higher than the 3rd of this terminal groove, wall 46,47 and this rest area 43 that arrives, the end 68 of this elastic arm is in harmony and is trimmed in the 3rd, wall 46,47; This pin portion 63 from first plate 64 of fixed part 61 puncture stamp out and extend downward in seat 40 lower ends, it connects a tin ball 613.
This loam cake 70 is to be provided with a capping 71 and two side 72, both sides, its rear end respectively are provided with an articulated section 73 that is the curved arc shape, be provided with a stopping plate 74 in the middle of the rear end, this articulated section 73 is articulated in second articulated section 35 of outer seat 30 rear ends of base, its front end is provided with two lugs 75, this two lug 75 is horizontal and protrudes forward, its capping 71 can press down the periphery of this wafer 90 when loam cake 70 is covered on base, in addition, loam cake 70 is starting when being vertical, and its stopping plate 74 can be butted on the rear end of outer seat 40 and unlikely dropping out.
This rocking bar 80, it is provided with first bar 81 and second bar 82 that is vertical mutually, this second bar 82 is articulated in first articulated section 34 of outer seat 30 front ends of base, and it is bent to form a nose bar 83, these first bar, 81 outer ends are bent to form a handgrip 84, when first bar 81 shook toward base rear end, this nose bar 83 can be suppressed the lug 75 of this loam cake 70, is electrically connected with these a plurality of terminals 60 and make loam cake 70 press down this wafer 90; As shown in Figure 5, this rocking bar 80 shook to when location, but its first bar, 81 fastenings clip of 40 36 times in this outside.
By above structure, because the elastic arm 62 of this terminal 60 extends to the terminal groove 41 in next door, so elastic arm 62 can have splendid elasticity; As shown in Figure 9, when wafer 90 is subjected to loam cake 70 compacting and during with termination contact, elastic arm 62 elasticity of this terminal receipts that contract, but the contact 91 of its contact 612 Elastic Contact wafers 90, the elastic arm 62 of this terminal is to go up by having a down dip to extend, so its terminal 41 that can not touch the next door causes short circuit, and because elastic arm epimere 610 corresponds to the perforate 611 of elastic arm hypomere of the terminal of next trough up and down, so when elastic arm 62 was depressed, its epimere 610 can get out of the way with the perforate 611 of the terminal of next trough more and guarantee not contact.
By above explanation, the present invention can have the following advantages:
1. the fixed part of terminal is set as the first folding plate 64 and second plate 65, the clamping part 66 that this first plate 64 like this can be provided with plate face broad is used third and fourth wall 46,47 packings with this terminal groove, the plate face of this second plate 65 can puncture and stamp out a clamping part 67 that protrudes and use second wall, 45 packings with this terminal groove, reach very convenient assembling and firm location, and good structural strength can be arranged owing to first plate 64 need not stamp out clamping part.
2. this terminal is controlled the length of elastic arm 62 by the length of second plate 65 of fixed part, and promptly shorter then root of elastic arm 62 of second plate 65 is healed low and made springing bigger, and the springing of anti-then elastic arm 62 is littler.
3. the end of the elastic arm 62 of this terminal extends to the terminal groove 41 in next door, the development length that can have long horizontal direction, preferable with the contact resilient of wafer, and it is to be by having a down dip to extend, so its terminal 41 that can not touch the next door causes short circuit when wafer is depressed.
4. the hypomere 69 of elastic arm is provided with perforate 611 and can uses and get out of the way epimere 610, though trim so the end 68 of this elastic arm is bent down to this third and fourth wall 46,47, when depressing, wafer need not still to worry that terminals of adjacent can touch mutually, and,, causes wafer 90 distortion of terminal so can not interfering with the end 68 of elastic arm when inserting rest area 43 because of the end 68 of elastic arm is not higher than third and fourth wall 46,47.
Seeing also Figure 10, is to be the second embodiment of the present invention, and it is roughly identical with first embodiment, and its difference is that the pin portion 63 of this terminal 60 is that second plate from fixed part stamps out.
Seeing also Figure 11, is to be the third embodiment of the present invention, and it is roughly identical with first embodiment, and its difference is that first clamping part 66 of the fixed part 61 of this terminal 60 is provided in a side of the both sides, upper end of second plate 65.
Seeing also Figure 12, is to be the fourth embodiment of the present invention, and it is roughly identical with first embodiment, and its difference is that the pin portion 63 of this terminal 60 is longitudinal extension.
Seeing also Figure 13, is to be the fifth embodiment of the present invention, and it is roughly identical with first embodiment, and its difference is that the elastic arm hypomere 69 of this terminal 60 is the ㄈ shape approximately.
The specific embodiment that is proposed in the detailed description of preferred embodiment is only in order to be easy to illustrate technology contents of the present invention, and be not with narrow sense of the present invention be limited to this embodiment, in fact, the present invention can make many variations and implement.
