Title:
SPRING-TYPE GROUND TERMINAL HAVING AN UPPER AND LOWER ELECTRICAL CONTACT STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2011/021821
Kind Code:
A2
Abstract:
The present invention relates to a spring-type ground terminal having an upper and lower electrical contact structure, to be used in components of an electrical machine and of an electronic machine. More particularly, the present invention relates to a spring-type ground terminal comprising an upper body (10), a lower body (20) and a coil spring unit (30) formed into a unitary body. The upper body (10) is formed from a resilient plate and is bent in the lengthwise direction so as to be formed into an upper ground portion (11). The lower body (20) is formed in the lengthwise direction so as to be formed into a lower ground portion (21). The coil spring unit (30) is formed by connecting upper and lower inclined connection portions (31, 32) which are arranged along the side surfaces of the upper body and the lower body and opposite each other in the vertical direction. The upper and lower inclined connection portions (31, 32) are wound into a spire around the outer surfaces of the upper ground portion (11) and the lower ground portion (21), respectively. The ground terminal resiliently contracts in the vertical direction when pressure is applied to the upper ground portion (11) and the lower ground portion (21), and is guided in the vertical direction by upper and lower guide portions (13, 23) arranged in the upper body (10) and the lower body (20), respectively. The ground terminal of the present invention can be simply produced by trimming and bending a resilient plate material, and is configured to resiliently contract in an effective manner when pressure is applied to the upper and lower ground portions, thus reducing manufacturing costs, and improving the productivity and operating reliability thereof.
