The base portion 21 of the electrical connector terminal 2 is formed with a penetration channel 20, and each base portion 21 is formed with a downward step 210 at the center, and has welding portions 211 extending outward on the front and rear sides, while the two sides are inward. There is a card slot 212 in the opposite section, and a fixing part 22 is bent upward on both sides of the base 21 between the welding part 211 and the card slot 212, and a plurality of thorns 221 are provided on the side of the fixing part 22. There are side plates 23 bent on the side, and a suspended elastic arm 231 is extended horizontally from each side plate 23 toward the rear. The pushing shrapnel 2311 and the clamping part 2312 are relatively bent, and a protruding buckling part 232 is provided on the front edge of the side plate 23, and a top plate 24 is bent at the top of the two side plates 23 by one of the side plates 23.

The clamping part 2312 set on the suspended elastic arm 231 is positioned at the default position on the base part 21 .

The center of the wire 4 is a conductor 41, and the outside is coated with an insulating layer 42, but the wire 4 of the present invention can also be a conductor 41 with electrical conductivity such as a plug conductive sheet or a conductive terminal. Such simple and equal changes and modifications should still be included within the scope of the present utility model.

Referring to Fig. 2, Fig. 3 and Fig. 4, a piercing channel 20 is formed on the base 21 of the terminal, and one side of the piercing channel 20 is for the wire 41 to enter and pass through, and the central conductor 41 of the wire 4 runs along the thread of the clamping terminal 2. The channel 20 enters and pushes the pressing piece 241 of the top plate 24 and the two clamping parts 2312 of the side plate 23 to elastically deform outwards, and the base part 21 is located between the suspended elastic arms 231 adjacent to the clamping part 2312. The elastic arm positioning part 213 elastically resisted by the inner wall surface of the suspended elastic arm 231 makes the clamping part 2312 set on the suspended elastic arm 231 be positioned at a better default position on the base part 21. The so-called better predetermined position refers to the second clamping part The gap formed between 2312 is preferably set near the axial center of the base 21, and the central conductor 41 can be clamped and positioned in multiple directions by the return elastic force of the pressing piece 241 and the two clamping parts 2312, and then The clamping terminal 2 is electrically connected to the conductor 41 by multiple contacts, and the positioning part of the spring arm is set to prevent the center conductor 41 of the wire 4 from being loose after being inserted. , and in this preferred embodiment, the elastic arm positioning part 213 is upwardly formed to form a circular convex point that protrudes into a semicircular longitudinal section. The shape of the surface is circular, oval, rhombus or any other shape of the cylinder (not shown in the figure) or upwards to form a convex shape of the cross-section of the shape of a circle, ellipse, rhombus or any other shape of the cone (not shown in the figure shown) can be.

Referring to Fig. 5, Fig. 6, Fig. 7 and Fig. 8, the electrical connector based on the electrical connector terminal 2 includes a seat body 1, the aforementioned electrical connector terminal 2 and a push block 3, wherein, when the present invention is assembled, it is First, force the two fixing parts 22 holding the terminal 2 into the fastening groove 11 of the accommodating space 10 of the base body 1 from bottom to top, so that the protruding thorns 221 interfere with the fastening groove 11 to form a position. The holding part 232 of the side plate 23 of the holding terminal 2 also interferes with the inner wall surface of the seat body 1 positioned next to the opening 101, while the second welding part 211 and the card slot 212 are respectively located inside the cut groove 12 and the convex buckle 13, and then push the The sliding cover 31 of the block 3 is pushed horizontally into the rail groove 14 by the pushing space 102, and its sliding block 311 enters the limit groove 15 over the lower surface of the seat body 1, and the sliding cover 31 enters the rail groove 14. At this time, its sliding block 311 It is located at the resisting surface 151 of the limiting groove 15 to prevent the pushing block 3 from protruding to the outside of the moving space 102 .

After the new model is assembled, the first position of the pushing surface 321 with the two sides in front of the push block 32 of the push block 3 inclined outwards is aligned and located outside the gap between the bent ends of the two suspended elastic arms 231 of the clamping terminal 2. The first position is to show the locking state of the clamping terminal 2 to the central conductor 41 of the wire 4. When in use, the first method is to firstly pass the central conductor 41 of the wire 4 through the opening 101, so that the conductor 41 is clamped along the The penetration channel 20 of the terminal 2 enters and pushes the pressing piece 241 of the top plate 24 and the two clamping parts 2312 of the side plate 23 to elastically deform outward, and can be reset by the pressing piece 241 and the two clamping parts 2312 The elastic force clamps and positions the central conductor 41 in multiple directions, so that the clamping terminal 2 and the conductor 41 are electrically connected with multiple contacts; 3. The missing groove 331 of the upper convex part 33 is pushed toward the limit groove 15, and the sliding cover 31 moves horizontally along the rail groove 14 so that the pushing surface 321 directly pushes the clamping terminal 2. The pushing shrapnel 2311 above the second suspended elastic arm 231 bends. The gap at the folding end elastically deforms outward. When the blocking part 312 of the sliding cover 31 contacts the inner side of the rail groove 14 and stops, the two elastic arms 231 also relatively slide into the positioning groove 3221 of the plane 322 to form the second position of the pushing surface 321. position, the gap between the pushing shrapnel 2311 of the second elastic arm 231 can be elastically deformed outward, and the second clamping portion 2312 of the second elastic arm 231 can also be elastically deformed outward, and the central conductor 41 of the wire 4 can be opened through the opening 101. Therefore, the above-mentioned second position is the release state of the central conductor 41 clamping the terminal 2 to the wire 4; in the second way, the sliding cover 31 of the push block 3 is first moved from the first position along the rail groove. 14 Horizontal movement makes the push surface 321 directly push the gap at the bent end of the shrapnel 2311 to elastically deform outward, and the second elastic arm 231 also relatively slides into the second position in the positioning groove 3221 of the plane 322, and then pushes the center of the wire 4 The conductor 41 penetrates through the opening 101, so that the conductor 41 enters the insertion channel 20 along the clamping terminal 2, and then the sliding cover 31 is pushed from the second position to the first position, so that the pushing surface 321 is horizontally separated from the clamping terminal 2 The second push shrapnel 2311 gap to the outside, and the conductor 41 can be clamped and positioned in multiple directions by the reset elastic force of the pressing piece 241 and the second clamping part 2312. If the conductor 41 is to be removed from the opening 101 outward , the central conductor 41 of the wire 4 can be removed outward from the opening 101 only by pushing the sliding cover 31 from the locked state at the first position to the released state at the second position.

However, no matter the above-mentioned electrical connector is the first method or the second method, when the wire 4 is removed, the push block 3 must be used to push the suspended elastic arm 231 to open, so that the wire 4 can exit or enter the electrical connector. Therefore, the base portion 21 of the electrical connector terminal 2 is between the suspended elastic arms 231 for the elastic arm positioning part 213 elastically supported by the inner wall surface of the suspended elastic arm, and the preferred default position of the elastic arm positioning part in this embodiment is The gap formed by the second push shrapnel 2311 is preferably set close to the axial center of the base 21, so that the second push shrapnel 2311 can be aligned with the push surface 321 of the push block 3, and when the push block 3 slides, it will not be affected by the terminal. 2 is not aligned, and the two push shrapnels 2311 are squeezed and deformed toward the same side, causing terminal 2 to be damaged.
