Snap-type electric multi-signal concentric connector system
View Patent ↗The invention relates to a modular connector system for printed circuit boards (PCBs) and cables, comprising male and female disks with spring-loaded pogo pins and concentric conductive rings to enable reliable multi-signal transmission. The system is enclosed in snap-fit assemblies that provide secure connections without requiring precise alignment, maintaining signal integrity even under rotational movement. It is compatible with both surface-mount technology (SMT) and through-hole soldering methods.

A connector system, comprising: a male disk ( 1 ) composed of a multilayer printed circuit board (PCB) having a set of spring-loaded pins ( 2 ) arranged in a specific pattern to minimize connector size; a female disk ( 8 ) composed of a multilayer PCB having concentric rings configured to provide reliable contact with the spring-loaded pins ( 2 ) from the male disk ( 1 ); a male snap ( 10 ) housing for the male disk ( 1 ), the male snap ( 10 ) including flexible snap-clips ( 11 ) configured to secure to a female snap ( 18 ); a female snap ( 18 ) housing for the female disk ( 8 ), the female snap ( 18 ) including a receiving ring ( 21 ) configured to accept the flexible snap-clips ( 11 ) from the male snap ( 10 ); wherein the connector system is configured to maintain continuous electrical contact across multiple signal types, regardless of rotational orientation between the male disk ( 1 ) and the female disk ( 8 ).
2 . The connector system of claim 1 , wherein the spring-loaded pins ( 2 ) are pogo pins available in multiple configurations, including Surface Mount Technology (SMT), Through-Hole (TH), Press-Fit (PF), and High-Current (HC), with diameters ranging from 0.5 mm to 4 mm and heights from 1.5 mm to 10 mm.
3 . The connector system of claim 2 , wherein the pogo pins ( 2 ) are plated with materials such as gold, nickel, or palladium, ensuring low contact resistance and high durability, with the ability to maintain electrical signal integrity in conditions of rotation and vibration.
4 . The connector system of claim 1 , wherein the male disk ( 1 ) includes multiple pogo pin mounting pads (MP 2 V, MP 2 G 1 , MP 2 G 2 , MP 2 A 1 , MP 2 A 2 , MP 2 B 1 , MP 2 B 2 , MP 2 C 1 , MP 2 C 2 ), symmetrically arranged in concentric patterns, ensuring reliable contact with the corresponding concentric rings on the female disk ( 8 ).
5 . The connector system of claim 1 , wherein the female disk ( 8 ) includes concentric rings ( 9 V, 9 G, 9 A, 9 B, 9 C) with varying radii to ensure reliable electrical contact with the spring-loaded pogo pins ( 2 ) of the male disk ( 1 ).
6 . The connector system of claim 1 , wherein the system supports multi-signal transmission, allowing the transfer of various signal types, including power, ground, voltage, communication bits, and sensor data, across multiple concentric layers.
7 . The connector system of claim 1 , wherein the male snap ( 10 ) and female snap ( 18 ) housings are designed to allow rotational freedom between the male and female disks while maintaining continuous electrical contact through the pogo pins and concentric rings.
8 . The connector system of claim 7 , wherein the male snap ( 10 ) and female snap ( 18 ) are secured using flexible snap-clips ( 11 ) and a receiving ring ( 21 ), and further include screw-ready mounting holes ( 12 ) and aligning mounting pins ( 13 ) to secure the assembly to PCBs or other components.
9 . The connector system of claim 1 , wherein the male snap ( 1 ) and female disk ( 8 ) are designed with optional shielding edges ( 5 ) to provide electromagnetic interference (EMI) protection, with corresponding internal layers for voltage, ground, and shielding.
10 . The connector system of claim 1 , wherein the male and female disks include an internal jumper system for connecting adjacent signals (G, A, B, C, S) using jumper pads, enabling flexible configurations and signal connections.
11 . The connector system of claim 1 , further comprising: a cable snap cap ( 32 ) for securely connecting cables to the male or female snap assembly, wherein the snap cap includes an internal chamber to accommodate signal cables, holes for threaded inserts ( 30 ), and aligning posts ( 35 ) for proper alignment and connection of the snap assembly.
12 . The connector system of claim 11 , wherein the cable snap cap ( 32 ) allows for epoxy sealing to ensure a reliable, solid assembly of the connector system when used in cable applications.
13 . The connector system of claim 1 , wherein the connector system is modular, allowing multiple modules to be interconnected using the male and female snap assemblies, with support for applications requiring multiple modules connected.
14 . The connector system of claim 1 , wherein the male and female disks support both Surface Mount Technology (SMT) and Through-Hole (TH) soldering methods, allowing flexibility in the connection to PCBs or other components.
15 . The connector system of claim 1 , further comprising: an intermediate disk ( 31 ) designed to minimize the connection distance between multiple modules, enabling signal transmission through male and female disks on both sides of the intermediate disk.
