Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Firstly, the memory bar and the memory slot in the related art are introduced.

FIG. 1 shows a schematic diagram of the appearance of a memory stick 100 provided in the related art. The memory stick 100 includes a memory stick body 120 and a plurality of connecting fingers 140 disposed on two sides of the memory stick body 120 . The memory stick body 120 has a random access memory (Synchronous Dynamic Random Access Memory, SDRAM), and the gold fingers 140 are arranged according to a predetermined rule. Usually, signal (Signal) type gold fingers S and ground (Gnd) type gold fingers G appear alternately, so as to reduce crosstalk between signal (Signal) type gold fingers S.

It should be noted that most of the gold fingers 140 in the memory stick 100 conform to the above rules, but there are some exceptions. Schematically, the above-mentioned staggered appearance rules appear in groups. For example, the arrangement rule of the first group of 10 cheats is: SGSGSGSGSG, and the arrangement rule of the second group of 10 cheats is: GSGSGSGSGS. In this way, between two adjacent sets of gold fingers, two signal type or two ground type gold fingers may be arranged together.

Referring to FIG. 2 and FIG. 3 together, FIG. 2 shows a schematic top view of a memory slot 200 provided in the related art, and FIG. 3 shows a schematic bottom view of the memory slot 200 provided in the related art. The memory slot 200 includes: a slot body 20 and slot pins 21 disposed in the slot body 20 .

As shown in FIG. 2 , an insertion slot 22 is provided at the center directly above the socket body 20 , and the insertion slot 22 is used for inserting the memory module 100 . The socket pins 21 are arranged side by side in two groups on both sides of the socket 22 . The two sets of socket pins 21 include a first set of socket pins 21a and a second set of socket pins 22b. When the memory stick 100 is inserted into the slot 22 , the contact ends on the top of the first group of socket pins 21 a and the second group of socket pins 22 b will clamp the gold finger 140 of the memory stick 100 .

As shown in FIG. 3 , the bottom of the memory slot 200 is the part connected with the circuit board. The bottom of the memory slot 200 includes two sets of pin fixing ends: a first set of pin fixing ends 21c and a second set of pin fixing ends 21d. The first group of pin fixing ends 21c are pin fixing ends corresponding to the first group of socket pins 21a, and the second group of pin fixing ends 21d are pin fixing ends corresponding to the second group of socket pins 21b.

When the fixing method is crimping, the pin fixing end 213 may be in the shape of a sheet or a ring; when the fixing method is welding, the pin fixing end 213 may be in the shape of a needle. In FIG. 4 , the pin-fixing end 213 is illustrated as an example.

Since the interval between two adjacent slot pins 21 is relatively close, the pin fixing ends 213 of two adjacent slot pins 21 are arranged in a staggered manner, and are located at the ends of the slot pins 21 arranged in odd positions. The pin fixed ends form a row of pin fixed ends, and the pin fixed ends of the slot pins 21 arranged in even positions form another row of pin fixed ends, so that the pin fixed ends have a larger space when crimping or welding. operating space.

In order to solve the problem in the related art that a plurality of signal (Signal) pins are adjacently arranged in an arrangement manner 26 , the signal crosstalk between the plurality of adjacently arranged signal pins 26 will be relatively large.
