Description

The utility model relates to a conductive connector, especially a zero-insertion force connector mainly used in a personal computer central processing unit (Central Process Unit referred to as CPU). It can maintain a better contact effect with the terminals (or pins) of the central processing unit.

Personal computers must be equipped with a central processing unit (CPU). In recent years, the main manufacturer of the central processing unit, that is, the American company INTEL, has continuously introduced central processing units with stronger functions and faster computing speeds. Therefore, the personal computer products sold on the market are constantly updated. In order to meet the ever-increasing needs of users, a connector is designed that does not require effort whether it is plugged in or pulled out, so that the central processing unit can be easily pulled out of the connector or inserted into the connector for timely replacement. The central processing unit fulfills the needs of computer upgrades.

The currently commonly used zero insertion force connector mainly includes a socket, and a conductive member of metal material is respectively installed in a plurality of sockets in each socket. The sockets allow insertion of multiple terminals of the integrated circuit. In order to achieve the purpose of "parts pull-out force", the integrated circuit will not be resisted by the conductive member during the process of inserting the integrated circuit into the jack, or during the process of being pulled out from the jack. After the terminal is inserted into the socket, the operating lever is pulled to push the sliding member covered on the socket to slide a short distance (usually 1mm) relative to the socket, so that the terminal moves to the position where the conductive member is located and the terminal squeezes Insert it between the conductive shrapnel of the two clips.

But existing constructions have the following disadvantages:

1. Since the elastic force of the two conductive shrapnels of the conductive member cannot be exactly the same, it is often the case that the elastic force of one of the conductive shrapnel is greater than that of the other conductive shrapnel to push the other conductive shrapnel away from the middle position, that is, it is impossible to make the two conductive shrapnels The two conductive shrapnels are correctly positioned, which makes it difficult for the terminals of the integrated circuit to squeeze smoothly between the two conductive shrapnels.

2. Due to manufacturing errors, the center of the gap between the two conductive shrapnels cannot be aligned with the center point of the jack, which makes it difficult for the terminals of the integrated circuit to squeeze smoothly between the two conductive shrapnels.

3. Since the conductive member has two conductive shrapnel, when manufacturing the conductive member, each conductive member must consume two pitches [Pitch, one pitch is 2.54mm, two pitches are 5.08mm] materials .

4. Since the pitch of the conductive components after stamping is 5.08mm, when inserting the entire row of conductive components into the socket holes with a pitch of 2.54mm, only half of the installation procedure is completed, that is, Only one conductive member is inserted every two pitches, and the socket holes of every two pitches are not inserted with conductive members, and the installation procedure must be carried out again to complete "one row" of socket holes. That is, a "secondary" installer must be performed to complete all installation work. Not only is this quite cumbersome, hinders the automated production process, but also is not efficient.

5. If the pitch of the conductive member after stamping is less than 5.08mm but greater than 2.54mm. Since the pitch is not equal to the standard 2.54mm, when the conductive member is to be loaded into the socket of the electrically insulating socket, only one conductive member can be installed at most in each installation step, and the installation efficiency is extremely low.

Therefore, the purpose of this utility model is to overcome the above-mentioned defects and provide an improved zero-insertion force connector, which is aimed at improving the structure of the conductive member and the socket in the zero-insertion force connector.

Please refer to Figures 1, 2, 3, 4, 5 and 6, the zero insertion force connector 20 provided by the utility model includes: an electrically insulating socket 21, a conductive member 23, a sliding member 26 and a metal operating rod 41. Among them, the above-mentioned electrically insulating sockets 21 have a plurality of insertion holes 22, and a plurality of conductive members 23 can be respectively installed therein. The above-mentioned sliding member 26 has a plurality of through holes 27, and these through holes 27 correspond to the above-mentioned jacks 22 one by one, and the above-mentioned sliding member 26 is placed on the above-mentioned socket 21, and can be moved from the above-mentioned operating rod 41 as shown in Figure 1 The unlocked position 41a shown in is rotated to the locked position 41b, so as to drive the sliding member 26 to slide from right to left along the surface of the socket 21. Alternatively, the operating lever 41 is rotated from the locked position to the released position 41 a, so as to drive the sliding member 26 to slide from left to right along the surface of the socket 21 .

Each of the insertion holes 22 of the electrical insulation socket 21 has an embedding hole 50 and an insertion hole 60 respectively. The embedding hole 50 has: a front wall 53 ; first and second positioning walls 54 , 55 ; a first side wall 51 and a second side wall 52 . The two positioning walls 54 , 55 are located on the same plane and are not connected to each other. The first and second positioning walls 54 , 55 are respectively opposed to the aforementioned front wall 53 . One side of the first side wall 51 is connected to one side of the front wall 53 , and the other side of the first side wall 51 is connected to one side of the first positioning wall 54 . One side of the second side wall 52 is connected to the other side of the front wall 53 , and the other side of the second side wall 52 is connected to one side of the second positioning wall 55 .

The insertion hole 60 is adjacent to the insertion hole 50 and communicates with each other, and an opening 61 is formed at the communicating position, and the opening 61 is connected between the first and second positioning walls 54 , 55 . The insertion hole 60 has: a rear wall 62 ; a third side wall 63 and a fourth side wall 64 . The aforementioned rear wall 62 and the front wall 53 are opposed to each other. One side of the third side wall 63 is connected to the other side of the first positioning wall 54 , and the other side of the third side wall 63 is connected to one side of the rear wall 62 . One side of the fourth side wall 64 is connected to the other side of the second positioning wall 55 , and the other side of the fourth side wall 64 is connected to the other side of the rear wall 62 .

A plurality of conductive members 23 are respectively installed in the insertion holes 22 of the electrically insulating socket 21 . Each conductive member 23 has: a pin portion 24 ; and a spring portion 25 extending from the pin portion 24 . Both sides of the free end of the elastic portion 25 have stop portions 31 , 32 . The width Wc of both sides of the stopper portion 31, 32 is greater than the width Wa of the opening 61, and the width Wc of both sides of the stopper portion 31, 32 is smaller than the distance Wb between the first sidewall 51 and the second sidewall 52, The two sides of the stoppers 31 and 32 are pressed against the two positioning walls 54 and 55 respectively. Since the elastic portion 25 of the conductive member 23 is in a free state, the vertical width D from the elastic portion 25 to the pin portion 24 (as shown in FIG. 5 ) is greater than the distance from the front wall 53 of the above-mentioned embedded hole 50 to the opening 61. L (as shown in Figure 3). Therefore, after the above-mentioned conductive member 23 is installed in the embedment hole 50, the vertical distance formed between the elastic part 25 and the pin in a free state is compressed by the smaller embedment hole 50 and is pre-determined. pressure, thus making the elastic portion 25 of the conductive member 23 lean against the first and second positioning walls 54, 55 of the above-mentioned embedded hole portion 50, and thus make the elastic portion 25 be held by the two positioning walls 54, 55 exerts preload and precise positioning, so that the terminal A of the integrated circuit B moving from the insertion hole 60 of the above-mentioned insertion hole 22 to the above-mentioned embedded hole 50 is given by the elastic part 25 of the above-mentioned conductive member 23. Precise contact pressure. Not only the terminal A of the integrated circuit B can be smoothly inserted into the insertion hole 60 without encountering any obstacles, but also the terminal A of the integrated circuit B is pressed into contact with the spring part 25 once it is carried to the locking position by the sliding member 26 At the same time, the elastic part 25 can apply a sufficient pressure to the terminal A of the integrated circuit B, so that the contact effect between the two is better.

In addition, the first embodiment of the conductive member 23 shown in FIGS. 5 and 6 has double-layer elastic parts 25 and 25, but the two elastic parts 25 are in contact with each other in a free state.

As shown in Figure 7, when the terminal A of the integrated circuit B is inserted into the insertion hole 60 of the electrical insulation socket 21, and is pushed to the spring part 25 as shown in Figure 8, two spring parts of different heights (lengths) 25 will contact the upper and lower two positions of terminal A respectively. In this way, not only there are more contact points between the conductive member 23 and the terminal A, and the contact effect is better; moreover, the contact pressure exerted by the elastic part 25 on the terminal A is more sufficient. As shown in FIGS. 4 and 5 , the inserting portion 30 integrally extends from the upper end of the pin portion 24 , so that it can be more firmly embedded in the inserting hole 50 .

As shown in Figures 9 and 10, the insertion hole 60 is longer, and the sliding member 26 extends downwards out of the pusher 35. The pusher 35 can extend into the insertion hole 60 and be close to the right side of the terminal A, which can Supporting the terminal A and pushing it to the left together with the terminal A (that is, toward the direction of the elastic part 25 ) can withstand the large contact pressure exerted by the elastic part 25 on the terminal A without causing the terminal A to bend and deform. If the pushing part 35 is provided, the elastic force of the spring part 25 is relatively large, or the terminal A of the integrated circuit B is relatively strong, or the spring force of the spring part 25 is small, and the pushing part 35 is unnecessary. Various embodiments of the conductive member described below can also be used in conjunction with the pushing part 35 according to the above principle.

As shown in Figures 11 and 12, the second embodiment of the conductive member 23 of the present invention is shown. It differs from the first embodiment of the conductive member shown in Figures 5 and 6 as follows: the embedded part 30 of the second embodiment of the conductive member 23 shown in Figures 11 and 12 is shorter, while that shown in Figures 5 and 6 The embedding portion 30 of the first embodiment showing the conductive member 23 is longer. The rest of the parts are roughly the same.

As shown in the third embodiment of the conductive member 23 shown in Figs. 13 and 14, the free end 25a of the spring part 25 of the conductive member 23 is also provided with two stoppers 31, 32, whose functions are as described above. The two elastic parts 25 integrally extend from the folded part 40 on the side of the pin part 24 , and are folded from the folding line 28 to a state as shown in FIG. 13 . Moreover, the elastic portion 25 has two pieces, and is folded into a double-layer elastic portion 25 from the two folding lines 29, 36, 37 shown in FIG. 14 . This double-layer elastic part 25, after packing into the jack 22, the upper end of the double-layer elastic part 25 [that is, the free end is in a state of being up and down due to the difference in height (ie length)], can be connected with the terminal A Two contact parts with different heights are formed, and the contact efficiency is better.

The third embodiment of the conductive member shown in Figures 13 and 14 differs most from the first embodiment of the conductive member shown in Figures 5 and 6 in that the third embodiment of the conductive member shown in Figures 13 and 14 In the embodiment, due to the different folding methods, there is a gap 38 between the double-layer elastic parts 25 in the free state before being inserted into the socket. In addition, since the cutting shape is different, the embedded part formed is also different.

The fourth embodiment of the conductive member shown in Figures 15 and 16 differs from the third embodiment of the conductive member shown in Figures 13 and 14 in that: the two-layer elastic part 25 of the two embodiments is Cut to different edge shapes respectively.

The fifth embodiment of the conductive member 23 shown in FIGS. 17 and 18, the biggest difference between it and the fourth embodiment of the conductive member 23 shown in FIGS. In the fifth embodiment of the component 23, the elastic portion 25 has only a single layer, but in the fourth embodiment of the conductive portion shown in FIGS. 15 and 16, the elastic portion 25 has double layers.

The biggest difference between the sixth embodiment of the conductive member 23 shown in Figures 19 and 20 and the fifth embodiment of the conductive member 23 shown in Figures 17 and 18 is that the elastic parts of the two embodiments 25 and the embedding part 30 are respectively cut into different edge shapes.

In the seventh embodiment of the conductive member 23 shown in FIGS. 21 and 22 , its embedded portion 30 is disposed between the pin portion 24 and the elastic portion 25 , and the elastic portion 25 has only a single layer.

The biggest difference between the eighth embodiment of the conductive member shown in Figures 23 and 24 and the seventh embodiment of the conductive member 23 shown in Figures 21 and 22 is: In the seventh embodiment, its pin portion 24 and elastic portion 25 are both single-layer. However, in the eighth embodiment of the conductive member 23 shown in Figures 23 and 24, its pin part 24 and spring part 25 are all folded into double layers by the same metal, which is larger in strength and elasticity, and is suitable for use in Stronger terminals.

As shown in Figures 25, 26, 27 and 28 of the ninth embodiment of the conductive member, the embedded portion 30 of the conductive member 23 and the elastic portion 25 form an intersection angle of 90° (as shown in Figure 25 ). As shown in FIG. 28 , the conductive member 23 has been stamped and formed, but the elastic portion 25 has not yet been folded toward the embedded portion 30 . The advantage of this structure is that not only the elastic part 25 has a larger movable space, but also the embedded surface formed by the embedded part 30 is parallel to the elastic direction of the elastic part 25, so the embedded effect is better.

29 , 30 , 31 and 32 show the tenth embodiment of the conductive member, the embedded portion 30 of the conductive member 23 integrally extends upward with a resilient portion 25 and an insert 30 a respectively. The embedding piece 30 a is embedded in the long and narrow embedding groove 56 next to the embedding hole 50 , so that the entire conductive member 23 can be more firmly embedded in the socket 21 . Moreover, the movable space of the spring part 25 in the insertion hole part 50 is larger.

As shown in Figures 33 and 34, in order to make the sliding member 26 when in the unlocked position of the electrical insulating socket 21, the through hole 27 of the sliding member 26 can be aligned with the insertion hole 60 of the electrical insulating socket 21, so that The terminal A of the integrated circuit B is smoothly inserted into the insertion hole 60 ; or the terminal A of the integrated circuit B is easily pulled out from the insertion hole 60 . Therefore, as shown in FIGS. 33 and 34 , two U-shaped leaf springs 42 are installed between the electrically insulating socket 21 and the sliding member 26 . When the operating lever 41 shown in FIG. 2 is released from the locking position 41b shown in FIG. 2 , not only the elastic parts 25 of the plurality of conductive members 23 are used to respectively bounce the terminal A of the integrated circuit B from left to right. Moreover, the elastic force of the blade spring 42 is also used to jointly push the sliding member 26 from left to right along the socket 21 to the position of completely unlocking, so that the through hole 27 of the sliding member 26 is just aligned with the above-mentioned electrically insulating socket 21. Insert the hole portion 60 . Therefore, the terminal A of the integrated circuit B can be smoothly inserted into the insertion hole 60 of the electrically insulating socket 21 ; or the terminal A of the integrated circuit can be easily pulled out from the insertion hole 60 .

As shown in FIGS. 33 and 34 , two installation holes 43 are respectively provided at the front and back of the hollow hole 47 of the socket 21 . And two leaf-shaped springs 42 are respectively installed in the two mounting holes 43 . In addition, a recess 44 is respectively provided beside the two installation holes 43 . Moreover, two protrusions 46 integrally extend downwards under the sliding member 26 , and these two protrusions 46 respectively protrude into the aforementioned two recesses 44 . When the sliding member 26 moves to the left, the two protrusions 46 of the sliding member 26 respectively push the two blade-shaped springs 42 to deform. When the operating lever 41 shown in FIG. 2 is released from the locking position 41b as shown in the figure, not only the elastic parts 25 of the plurality of conductive members 23 are used to respectively bounce the terminal A of the integrated circuit B from left to right, And at the same time, the elastic force of the blade spring 42 can be used to push the two protrusions 46 respectively, so that the sliding member 26 can be pushed along the socket 21 from left to right.

Another embodiment shown in Figures 35 and 36, the difference between it and the embodiment shown in Figures 33 and 34 is that the embodiment shown in Figures 35 and 36 provides three leaf springs 42, and is distributed in Three corners of the hollow hole 47 of the socket 21 are hollowed out. But there are only two leaf springs 42 provided by the embodiment shown in FIGS. 33 and 34 , and they are distributed in the front and back of the hollow hole 47 of the socket 21 . In addition, the embodiment shown in FIGS. 35 and 36 utilizes two protrusions 46 integrally extending downward from the lower surface of the sliding member 26 to each push two blade-shaped springs 42 . However, in the embodiment shown in Figures 35 and 36, three recessed holes 48 are provided below the sliding member 26, so that one of the ends 42a of the three blade-shaped springs 42 stretches into the aforementioned three recessed holes 48 respectively. In order to use these three concave holes 48 to promote three leaf springs 42 respectively.

Another embodiment shown in Figures 37 and 38, the difference between it and the embodiment shown in Figures 33 and 34 is: the leaf spring 42 provided by the embodiment shown in Figures 37 and 38 has only one , and is provided on the connector 20 for pivoting the position of the operating lever 41 . But there are two leaf springs 42 provided by the embodiment shown in Figures 33 and 34, and they are distributed in the front and back positions of the hollow hole 47 of the socket 21.

The common point of the conductive members shown in the above figures is that the free ends of the elastic parts 25 are respectively provided with stoppers 31, 32, and these two stoppers 31 and 32 can not only be received by the aforementioned embedded hole 50 The stop function of the two positioning walls 54 and 55 makes the elastic part 25 accurately positioned, and the prestress is generated before the pressure is applied by the terminal A of the collector circuit. Therefore, once in contact with the terminal A, the elastic part 25 can exert a relatively large (that is, sufficient) contact pressure on the terminal A, so that the contact effect between the terminal A and the elastic part 25 is better and more superior. This point cannot be provided by the existing conductive member, which is the main application feature of the present utility model.

According to the above, the utility model is characterized as follows:

1. The improved socket hole can precisely position the elastic part of the conductive member, so that the terminals of the integrated circuit can be smoothly inserted into the socket hole of the socket every time.

2. Before the improved conductive member 23 is inserted into the socket 22, the vertical width D between the elastic part 25 and its pin part 24 is greater than the length L of the embedded hole 50, so once it is inserted into the insertion hole of the conductive member 23 After the portion 60, the shorter embedding hole portion 50 exerts a preload on the elastic portion 25 with a longer vertical distance D, so that the elastic portion 25 of the conductive member 23 is not pushed by the terminal A of the integrated circuit B. Before pressing, the elastic part has prestress, so once the terminal A comes into contact with the elastic part 25, the elastic part 25 can generate a relatively large elastic force and apply it to the terminal A without moving too much. Form a better contact effect.

3. The improved conductive member 23 uses less material, so one conductive member 23 can be produced for each pitch of the tape, and the material used is reduced by half.

4. The improved conductive member 23, due to the low material consumption, can produce a conductive member 23 for each pitch of the material tape, which is exactly in line with the pitch of the jacks 22 on the socket 21, so the jacks of each row 22 Only one installation procedure can be completed. The installation procedure is simplified and the installation efficiency is doubled.

5. The improved connector 20 has a blade-shaped spring 42 installed between the socket 21 and the sliding member 26 . Therefore, when the operating lever 41 shown in FIG. 2 is released from the locking position 41b shown in FIG.
