Abstract
Abstract This invention relates to an improved construction of a computer switch box, and, in particular comprises a data switch box which controls the switching of input and output signals of the data in a main frame. The improved construction of the interior structural body includes a combination of a circuit board, an input terminal seat, multiple sockets, an assembly of a plurality of pins arranged in rows, and multiple output terminal seats. By separately inserting an assembly of multiple pins arranged in rows into multiple corresponding sockets, the electric current is conducted through each of the input and output points, which will have been previously determined.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
205 words
In a computer switch box having an input terminal seat, a plurality of output terminal seat as, a plurality of socket assemblies, and a circuit board on which are mounted the plurality of socket assemblies, the improvement comprising said input and output terminal seats including clamping means protruding from bottom portions thereof which clamp said input terminal seat and said plurality of output terminal seats to locations along a periphery of said circuit board; said plurality of socket assemblies each including a plurality of terminal means protruding from a lower end thereof which extend into a plurality of groove holes, said groove holes preset near a center of said circuit board; plural pin assemblies each having pins assembled in rows, and said pin assemblies connected to said socket assemblies; a plurality of fixed iron pieces contacting and connecting the pin assemblies and located within an interior of said computer switch box; and wherein each of said plurality of pin assemblies is shaped similarly to a socket assembly and includes an outer shell, an insulated damper installed in said outer shell, a plurality of conductive pieces set in a lower portion of said damper, said conductive pieces including a pair of holes pierced by said pins.
Claim 2
Dependent Claim
205 words
In a computer switch box having an input terminal seat, a plurality of output terminal seat as, a plurality of socket assemblies, and a circuit board on which are mounted the plurality of socket assemblies, the improvement comprising said input and output terminal seats including clamping means protruding from bottom portions thereof which clamp said input terminal seat and said plurality of output terminal seats to locations along a periphery of said circuit board; said plurality of socket assemblies each including a plurality of terminal means protruding from a lower end thereof which extend into a plurality of groove holes, said groove holes preset near a center of said circuit board; plural pin assemblies each having pins assembled in rows, and said pin assemblies connected to said socket assemblies; a plurality of fixed iron pieces contacting and connecting the pin assemblies and located within an interior of said computer switch box; and wherein each of said plurality of pin assemblies is shaped similarly to a socket assembly and includes an outer shell, an insulated damper installed in said outer shell, a plurality of conductive pieces set in a lower portion of said damper, said conductive pieces including a pair of holes pierced by said pins.
Claim 3
Dependent Claim
76 words
An improved computer switch box as recited in claim 1 wherein said socket assemblies each comprise a rectangular body having a plurality of grooved socket holes arranged side by side and wherein a terminal having a spring portion affixed to an upper portion thereof is fixed to a lower portion of each of said grooved socket holes; said terminals providing means connecting said socket assemblies to predetermined positions along an upper portion of said circuit board.
Claim 4
Dependent Claim
166 words
An improved computer switch box as recited in claim 2 further including a plurality of control blocks, said pins fixed in opposing pairs so that two pairs face another two pairs, convex blocks provided at a lower edge of said outer shell for squeezing against said pins; a control lever set adjacent a central part of an upper portion of said conductive piece; said control lever inserted into a control block having a convex piece attached to an upper portion thereof by a spring and button; said control blocks being fixed in the interior of a corresponding one of said fixed iron pieces; a sliding block separately squeezed by one of the lateral sides of said control blocks against an interior of a groove hole previously set in said control block; and a spring located in a concave groove at an opposite lateral side of said control block while the other end of said spring is housed in a bending wing edge of said sliding block.
