Description

Central processing unit socket terminal

The utility model relates to a kind of conducting terminal, refers in particular to a kind of conducting terminal that is used in the zero insertion force central processing unit socket.

Existing central processing unit socket sees also United States Patent (USP) the 4th with terminal, 988, No. 310 and TaiWan, China patent application the 83203222nd, 83208396,83212046, cases such as No. 83212081, wherein No. 83208396 disclosed terminal structure of case in Taiwan sees also Figure 1 and Figure 2 again, terminal 1 is provided with base 10 with the jack of fixing terminal 1 on socket, extend upward the portion of stretching 11 that is provided with at base 10, and turn over a suitable angle to the central processing unit direction of insertion and be provided with curved face part in the last portion 11 of stretching, on this curved face part, be provided with the contact site 110 that engages with central processing unit end pin in addition, be provided with guidance part 111 at contact site 110 in the other direction to 2 slippages of central processing unit end pin again, move until contacting with guiding central processing unit end pin 2, thereby and form with terminal 1 and electrically to engage with contact site 110.Being provided with down the portion of stretching 12 from base 10 extension downwards electrically engages also to form with circuit board (not shown).Though but this class mode can realize electrically connecting the purpose of circuit board and central processing unit, and since on stretch portion 11 and have certain elasticity, also can make terminal 1 and central processing unit end pin 2 be in preferable bonding state, but described terminal structure still has the space of improvement, it mainly improves the curved face part that emphasis then is terminal 1 must be provided with contact site 110, and central processing unit end pin 2 is to engage with contact site 110, must can reach through the lateral steering of guidance part 111 again, so terminal 1 must be designed guidance part 111, like this then make terminal 1 and the lateral length L1 and the D1 that accommodate the receptacle sockets of terminal 1 can't obtain very big reduction space, and the development of current electric connector is an integrated more function under the condition of constant size, this certainly will will increase the deploying density of terminal, above-mentioned terminal structure is then because its lateral dimension is excessive, and can't be suitable for this class occasion, therefore, for adapting to the development of current information industry, a kind ofly can on same area, carry out the central processing unit socket that high density row joins and then seem particularly necessary with terminal so design.

The purpose of this utility model is, a kind of central processing unit socket terminal that terminal guidance part and contact site are united two into one is provided.

The utility model is formed by the sheet material punching out, it is plugged in the jack of central processing unit socket to connect central processing unit end pin and circuit board, include: base portion, be installed in the central processing unit receptacle sockets, it is provided with the interference part to interfere the fixing conducting terminal in jack in both sides; Contact site extends to the central processing unit direction of insertion from base portion, and it is provided with curved face part and is bonded with each other with guiding central processing unit end pin and this curved face part, and wherein this curved face part can be rotating shaft with aforementioned terminal longitudinal centre line by sheet material, forms through reversing; Pin, the opposite direction from base portion towards terminal and central processing unit end pin contact site is extended.In addition, terminal also can be on the pin end be planted solder ball electrically connecting with circuit board, and its curved face part can be done a plane towards the central processing unit direction of insertion and extends.

Another being characterised in that of the present utility model, the curved face part of this terminal can be formed through at least twice bending along not parallel straight line by flat board, and it can move extension in the other direction and an outstanding guiding position is set towards the end pin at the position that guiding central processing unit end pin engages.

Compare prior art, the utility model advantage is that it can effectively reduce the terminal length overall and be suitable for highdensity central processing unit socket use.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Figure 10 is the schematic diagram that the terminal among the utility model second embodiment engages with central processing unit end pin.

See also Fig. 3, Fig. 4, Fig. 5, the utility model 3 is formed by the sheet material punching out, include the base portion 30 in the jack 6 that is installed in central processing unit socket 5, and this base portion 30 is provided with direction to central processing unit (not shown) and extends and to be provided with contact site 31 certainly, again from base portion 30 reverse extensions then are provided with and circuit board (not shown) is bonded with each other pin 32.Wherein, this base portion 30 comprises a body 300 and is located at the interference part 301 of body 300 both sides, and wherein in the present embodiment, this interference part 301 is meant the hangnail structure, borrows this interference part 301 can interfere fixing terminal 3 in jack 6.Contact site 31 is provided with curved face part 310 and inserts and do electrically to contact with this curved face part 310 with guiding central processing unit end pin 4 (with reference to Fig. 6), and the position that contacts with central processing unit end pin 4 on the curved face part is made as junction surface 312, certainly this junction surface 312 is then extended towards the opposite direction that moves of end pin 4 and is provided with guidance part 311, wherein in this first embodiment, this curved face part 310 is to be rotating shaft by contact site 31 with terminal 3 longitudinal centre lines, and one is reversed and formed.

See also shown in Figure 6, when 3 groups of the utility model are gone into the jack 6 of central processing unit socket 5, central processing unit end pin 4 contacts with guidance part 311 earlier, guiding by guidance part 311 is done electrically to contact with junction surface 312 then, and in this whole process, central processing unit end pin 4 is to contact with the utility model 3 gradually, its contact stress rises mild, and because guidance part 311 unites two into one with junction surface 312, so can effectively reduce the lateral dimension L2 of terminal 3, and and then reduce the lateral dimension D2 of the jack 6 of socket 5, so be fit to be used on the high density socket.In addition, terminal 3 also can be planted solder ball (not shown) electrically connecting with circuit board at pin 32 ends, and its curved face part also can be done the plane towards the central processing unit direction of insertion and extends.

Continuous Fig. 7, Fig. 8, Fig. 9 of please refer to, be the utility model second embodiment, the difference of itself and first embodiment is, curved face part 310 ' be to form through at least twice bending along not parallel straight line by sheet material, by such design also can realize first embodiment in one's power reduce terminal 3 ' with jack 6 ' lateral dimension L3 and the effect (consulting Figure 10) of D3, use and be useful in highdensity central processing unit socket equally.And this terminal 3 ' also can extend and an outstanding guiding position is set along the opposite direction that the position that guiding central processing unit end pin engages be moved towards central processing unit

Promptly can be made into because the utility model 3,3 ' only needs to carry out simple bending to plate, and shortened terminal 3,3 ' lateral dimension, thereby remove applicablely at highdensity central processing unit socket, can save production cost again and be suitable for a large amount of productions.
