Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to miniature rectangular electrical connectors. Background Technology

[0002] Miniature electrical connectors are widely used in high-density electronic devices (such as portable medical devices and miniature sensors), but traditional designs face significant bottlenecks in optimizing miniaturization and reliability: 1. Contact stability defects: Solid pins or sheet-like contacts are prone to stress concentration at single points due to insertion and removal misalignment, leading to increased contact resistance after repeated insertion and removal, and even the risk of open circuit; 2. Limited contact density: Conventional elastic pins mostly use linear spring structures, which are difficult to exceed the limit of the number of contacts per unit area in miniaturization scenarios, restricting the demand for high-density signal transmission; 3. Weak resistance to micro-vibration: Miniature devices are more susceptible to external vibration due to their reduced size, and traditional pins lack dynamic adaptive compensation mechanisms, making them prone to signal interruption due to micro-displacement. Therefore, miniature rectangular electrical connectors are proposed. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] A miniature rectangular electrical connector includes a socket body and a plug body inserted into the top of the socket body. A protruding shell is provided between the socket body and the plug body, formed at the top of the socket body and vertically inserted into the bottom of the plug body. A first LCP core is horizontally disposed at the top of the protruding shell, and several second sleeves are vertically inserted into the first LCP core. All the second sleeves are vertically located inside the socket body, with their bottom ends located at the bottom of the socket body and curved. The top ends of the second sleeves are inserted into the plug body. A second LCP core is horizontally disposed at the bottom of the plug body. Furthermore, the second LCP core is vertically inserted with several first sleeves, and these first sleeves are all vertically located inside the plug body. The top of the first sleeve is located at the top of the plug body, and the top of the first sleeve is curved. The top of the second sleeve is vertically inserted with a pin, and the other end of the pin is vertically inserted into the bottom of the first sleeve. The pin connects the first sleeve and the second sleeve, so that they can be connected when the first sleeve and the second sleeve are energized respectively. The pin is twisted, which makes the contact density of the pin high, thus making the insertion and assembly between the plug body and the socket body and the connection between the first sleeve and the second sleeve smoother.

[0005] A second high-temperature resistant epoxy resin is disposed between the first sleeve and the plug body, and the second high-temperature resistant epoxy resin is laterally located inside the plug body, and the first sleeve penetrates through the second high-temperature resistant epoxy resin, thereby fixing the first sleeve inside the plug body through the second high-temperature resistant epoxy resin.

[0006] A first high-temperature resistant epoxy resin is provided between the second sleeve and the socket body, and the first high-temperature resistant epoxy resin is laterally located inside the socket body. The second sleeve penetrates through the first high-temperature resistant epoxy resin, thereby fixing the second sleeve inside the socket body through the first high-temperature resistant epoxy resin.

[0007] An anti-rotation groove is provided between the socket body and the plug body, and the anti-rotation groove is formed at the bottom of the plug body. The anti-rotation groove is arched upward, and a convex shell is inserted into the anti-rotation groove. Thus, the insertion and cooperation between the convex shell and the anti-rotation groove ensures that the socket body and the plug body will not be misaligned when assembled.

[0008] The pin and the first sleeve are provided with insertion holes, and the insertion holes are formed at the bottom end of the first sleeve. The insertion holes are arched upwards, and the pin is vertically inserted into the insertion holes, so that the first sleeve and the second sleeve can be connected by insertion through the insertion and cooperation between the pin and the insertion holes.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. The pins (twisted) utilize multi-strand spiral twisting to generate uniform distributed elasticity, increasing the contact density to 80-100 points / cm. 2 Meanwhile, by distributing the insertion and extraction stress through multi-point contact, the contact resistance fluctuation range is ≤5%; the stranded wire structure spontaneously forms radial adaptive deformation during insertion, compensating for the assembly tolerance within ±0.3mm between the plug and socket.

[0011] 2. The bending design at the bottom of the first and second sleeves forms a mechanical stress buffer section, reducing the shear force of the insertion and extraction torque on the welding point (peak stress reduced by 40%).

[0012] 3. The convex shell and the plug body form a dual guiding structure. The limiting groove on the edge of the convex shell is precisely aligned with the protrusion at the bottom of the plug to ensure synchronous engagement of the pin group (interlocking force deviation ≤ ±10%). The first / second LCP cores are arranged vertically and crosswise to achieve layered isolation of the core space and avoid cross-interference of parallel signals.

[0013] 4. Even if a single strand of the stranded wire pin breaks, the circuit can still be maintained by the remaining stranded wire, which increases the fault tolerance rate by 6 times compared to the solid pin (experimental life ≥ 5000 insertion and removal cycles); the second sleeve and the first LCP core adopt a crimp-type insertion, which can partially disassemble and replace the damaged contacts, avoiding overall scrapping.
