Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a DDR connector with highly stable terminals. Background Technology

[0002] DDR, Double Data Rate Synchronous Dynamic Random Access Memory, should strictly be called DDR SDRAM, but is commonly referred to as DDR memory. A DDR connector is a connector that connects memory modules to the circuit board. For this type of storage product, the contact performance between the memory module and the DDR connector, as well as the soldering performance between the DDR connector and the circuit board, has a significant impact on the quality of the device. Current DDR connectors typically have a vertical structure, where the memory card stands upright after being inserted into the connector. Furthermore, most DDR connectors are elongated, with slots on the body for the card to be inserted and electrically connected to the terminals within the slots, thus enabling data transmission.

[0003] With the advancement of technology, electronic products are demanding increasingly higher data transmission rates while requiring smaller form factors. This necessitates DDR connectors to simultaneously meet high-speed signal transmission requirements and ensure stable terminal contact within a limited space. However, existing DDR connectors struggle to achieve this dual capability because stress concentration within the terminals after molding leads to easy subsidence, limiting the contact travel between the terminals and the memory card. Therefore, improvements to existing connectors are necessary. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a DDR connector with highly stable terminals, which can effectively solve the problem of stress concentration inside the terminals of existing DDR connectors, easy subsidence, and the inability of the terminals and memory cards to have a greater contact stroke.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A DDR connector with highly stable terminals includes a main body, multiple terminals, and two latches. The main body has an upward-facing slot with multiple terminal slots. The multiple terminals are respectively disposed in their corresponding terminal slots, and each terminal has a contact portion and a solder portion. Each contact portion extends outward from the terminal slot into the slot, and each solder portion extends outward from the main body. The two latches are respectively disposed at both ends of the main body. Each terminal includes a first horizontal segment, a first vertical segment, a first bent segment, a second vertical segment, a second bent segment, a third bent segment, a second horizontal segment, and a third vertical segment integrally formed and connected from bottom to top. The first horizontal segment is bent upward at one end, the first bent segment is bent upward at the upper end of the first vertical segment, the second vertical segment is bent upward at the upper end of the first bent segment, the second bent segment is bent upward at the upper end of the second vertical segment, the third bent segment is bent upward at the upper end of the second bent segment, the second horizontal segment is bent upward at the upper end of the third bent segment, and the third vertical segment is bent upward at one end of the second horizontal segment. The first, second, and third bent segments all form an angle with the horizontal line, and the angle is acute. The aforementioned contact part is located between the second and third bent segments, and the aforementioned welded part is located on the first horizontal segment.

[0007] As a preferred embodiment, the upper inner wall of the terminal slot has a limiting protrusion, and the third vertical segment has a limiting portion that abuts against the upper limit of the limiting protrusion.

[0008] As a preferred embodiment, a fixing groove is provided on the lower side of the main body, and a fixing component is provided in the fixing groove.

[0009] As a preferred embodiment, the fastener includes a body and a fixing foot, the body being disposed within a fixing groove, and the fixing foot extending downward from the lower side of the body.

[0010] As a preferred embodiment, the fixing foot is provided with a fixing hole.

[0011] As a preferred embodiment, there are three fixing slots, which are respectively opened at both ends and the middle of the lower side of the main body. Correspondingly, there are also three fixing members, which are respectively set in the corresponding fixing slots.

[0012] As a preferred embodiment, the main body has multiple stress relief grooves on its peripheral side, and these multiple stress relief grooves are arranged at intervals on the left and right sides.

[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0014] The terminal comprises a first horizontal segment, a first vertical segment, a first bent segment, a second vertical segment, a second bent segment, a third bent segment, a second horizontal segment, and a third vertical segment, all integrally formed and connected from bottom to top. This design features multiple bends, which reduces internal stress concentration and makes the terminal less prone to subsidence.

Furthermore, the multiple bends give the terminal better elasticity, effectively improving the contact stability between the terminal and the memory card.
