Description

Technical Field

[0001] The utility model relates to the technical field of PCB board gold finger connectors, in particular to a memory stick connector capable of quickly switching assembly forms. Background Art

[0002] DDR connector is a memory bar connector used to connect the motherboard and memory bar of a computer. DDR is the abbreviation of "Double Data Rate", which means "double data transfer rate", and mainly refers to the rate at which memory transfers data. DDR connectors are widely used in computer fields such as personal computers, servers, workstations, and embedded systems. For the two types of DDR5 memory bars RDIMM / UDIMM, although the two types have the same external dimensions and number of pins, there are still differences in form. The distance from the center of the key / middle metal foot to the center of the terminal is different, about 4.3mm for the RDIMM type and about 1.85mm for the UDIMM type. The general design for the above differences is to design a separate memory bar connector for matching connection. Therefore, the production of these two types of memory bar connectors requires two separate sets of molds to process and produce the connector plastic body. The connector plastic body is assembled with metal terminals, ear buckles, and metal feet to process into two types of connectors. It is necessary to prepare the plastic bodies of the two types of connectors, classify and store them to avoid mixing. Therefore, the existing technical conditions will generate pressure on stock preparation for the production and processing of the two types of memory bar connectors RDIMM / UDIMM for DDR5 memory bars. There is a problem that one of the two materials is in excess, while the other is insufficient. Further research and development and improvement of the existing DDR5 memory stick connector is needed to solve the above technical problems. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this solution proposes a memory stick connector that can quickly switch assembly forms. The plastic body of the connector can switch between RDIMM / UDIMM DDR5 memory sticks, thereby solving the problem of existing single-form stocking, which is prone to inventory pressure and excess of one material and shortage of the other.

[0004] The technical solution adopted by the utility model is: a memory stick connection part with a fast switching assembly form, including a connector body, the connector body is in a long strip shape, a plug-in slot is arranged on the top surface of the connector body along the length direction, a plurality of metal terminals are arranged on both sides of the plug-in slot, and ear buckles and metal feet are arranged at both ends of the connector body. The plug-in slot is provided with a first slot and a second slot near the middle position, and a metal spring is arranged in the first slot and the second slot in a plug-in manner, and the metal spring is in a U-shape as a whole, and the U-shaped mouth of the metal spring is inserted downward into the first slot or the second slot, so as to quickly switch the connector body to correspond to the memory stick processing and production.

[0005] Furthermore, the first slot and the second slot are two groups of U-shaped slots that are concave toward the side walls and are arranged at relative positions on the left and right side walls of the plug-in slot. The bottom wall or side wall of the U-shaped slot and the metal spring sheet are provided with a matching snap-fit ​​structure.

[0006] Optionally, the clamping structure is provided with a first clamping portion on the front side or the rear side of the groove bottom wall, and second clamping portions are provided on both side edges of the metal spring sheet.

[0007] Optionally, the first clamping portion is a reverse hook portion, and the second clamping portion is a convex hook portion adapted for clamping.

[0008] Optionally, the clamping structure is a third clamping portion provided on the side wall of the groove, and a fourth clamping portion is provided on the front or rear side of the U-shaped metal spring.

[0009] Optionally, the third clamping portion is a rectangular notch that is concave toward the side wall of the groove, and the fourth clamping portion is an outward-turned clamping portion that is cut out from both side edges of the front or rear side of the metal spring.

[0010] Optionally, a through hole is provided at the bottom of the first slot and the second slot, one end of the metal spring extends downward to form a plug-in portion, and the plug-in portion is inserted through the through hole.

[0011] Furthermore, one end of the metal spring is bent obliquely downward toward the other end to extend into an inclined extension portion, and the lower end of the inclined extension portion is vertically extended downward to form an inserting portion, and one side hole wall of the through hole is set as an inclined hole wall to adapt to the inserting inclined extension portion.

[0012] Optionally, a through-hole welding portion or a U-shaped notch welding portion is provided on the lower end plate surface of the plug-in portion passing through the through-hole portion.

[0013] Optionally, both side edges of the lower end plate surface of the inserting portion passing through the through hole are provided with snap-fitting side wings that protrude outward and then extend obliquely downward.

[0014] The beneficial effects of the utility model are as follows: the memory bar connector designed by the technical solution is mainly universal for the two forms of memory bar connectors of RDIMM / UDIMM of DDR5, and can be assembled by the metal springs corresponding to the two slots. Because when the metal spring is plugged into the corresponding memory bar, the anti-stuck mouth of the memory bar is plugged into the metal spring, and the metal spring is elastic, and there can be a certain deformation variable distance on the left and right, so it can realize the rapid switching and assembly of the memory bar connector that adapts to the corresponding memory bar. Thereby avoiding the traditional production of the two forms of memory card connectors through two separate sets of molds to process and produce the connector plastic body, the connector plastic body assembling metal terminals, ear buckles, and metal feet into two types of connectors, and the need to prepare the two types of connector plastic bodies and classify and store them to avoid mixing. Only the connector body designed by this solution needs to be prepared to achieve the application of processing two forms of memory bar connectors, reducing the preparation of one material and reducing the pressure of material storage. And it plays a convenient role in production and processing, without the need to specially separate materials.

[0015] In addition, the anti-stuck opening of the conventional memory stick connector for inserting the memory stick is a stopper part that is integrally molded with the plastic body. The plastic is easily damaged when the inner stick is inserted reversely, thereby affecting the strength of the connector slot and affecting the normal contact between the gold finger of the memory stick and the metal terminal. The design of the slot and the metal spring of this solution is conducive to avoiding the above problems. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] To this end, the main innovative design of the technical solution is that the first slot 12 and the second slot 13 are provided near the middle position of the plug-in slot 11, and the metal spring 3 is pluggable in the first slot 12 and the second slot 13.

When the metal spring 3 is plugged into the corresponding memory stick, the foolproof mouth of the memory stick is plugged into the metal spring 3. The metal spring 3 is elastic and can have a certain deformation variable distance on the left and right, so it can realize the rapid switching and assembly of the memory stick connector that adapts to the corresponding memory stick. It is applicable to the processing of two forms of memory stick connectors, reducing the preparation of a material and reducing the pressure of material storage.

[0030] Figure 3As shown, the letter "R" is marked on the side of the first slot 12 on the connector body 1, that is, the metal spring 3 is inserted into the first slot 12, and the memory stick connector is suitable for inserting and using a DDR5 memory stick RDIMM type memory stick.

[0031] Figure 4 As shown, the letter "U" is marked on the side of the second slot 13 on the connector body 1, that is, the metal spring 3 is inserted into the second slot 13, and the memory stick connector is suitable for inserting and using a DDR5 memory stick UDIMM type memory stick.

[0032] As a preferred embodiment of the specific structure of the first slot 12 and the second slot 13, the first slot 12 and the second slot 13 are two groups of U-shaped slots 121 recessed toward the side walls arranged at relative positions on the left and right side walls of the plug-in slot, and the slot bottom wall 1211 or the slot side wall 1212 formed by the U-shaped slot 121 and the metal spring 3 are provided with a matching snap-in structure.

[0033] Reference Figure 5 , Figure 7 and Figure 8 Optionally, the clamping structure is provided with a first clamping portion on the front or rear side of the groove bottom wall 1211, and a second clamping portion is provided on both sides of the metal spring 3. The first clamping portion is a reverse hook portion 12111, and the second clamping portion is a convex hook portion 301 adapted for clamping.

[0034] Reference Figure 6 , Fig. 9 and Fig.10 Optionally, the clamping structure is provided with a third clamping portion on the groove side wall 1212, and a fourth clamping portion is provided on the front or rear of the U-shaped metal spring 3. The third clamping portion is a rectangular notch 12121 concave inwardly toward the groove side wall, and the fourth clamping portion is an outward-turned clamping portion 302 cut out of both sides of the front or rear of the metal spring 3.

[0035] The groove bottom wall 1211 or the groove side wall 1212 formed by the above-mentioned U-shaped groove 121 is provided with a matching clamping structure with the metal spring piece 3, so as to realize the rapid installation and fixing of the metal spring piece 3 to the first slot 12 and the second slot 13, and the assembly is simple and can realize automatic assembly.
