2. Description of the Related Art
-
A common terminal structure for use with a typical electronic device is adapted to make an electrical connection, thereby electrically connecting various electronic components located in the electronic device.
-
For example, a common terminal structure includes an insulation housing and a connection terminal disposed therein. The connection clamp has an elastic clamping arm. To make an electrical connection, an electrical wire is passed through a through bore of the insulation housing to reach the connection terminal and to set the elastic clamping arm in motion. Then, the electric wire is clamped by the connection terminal by an elastic force generated by the elastic clamp arm, thereby establishing the electrical connection.

BRIEF SUMMARY OF THE INVENTION
-
A terminal structure of the present invention comprises a base member and a clamping member. The base element is bent in an L-shape and comprises a longitudinal arm and a transverse arm, which is connected to the longitudinal arm. An upper end of the longitudinal arm forms an engagement flange and an engagement shoulder portion. A right end of the transverse arm forms a coupling section. The clamping element comprises an elastic clamping arm, a support arm and a connecting arm. The connecting arm forms an opening portion and extends from the support arm to the longitudinal arm. The opening portion of the connecting arm is set around the engagement shoulder portion and engages therewith. A lower end of the support arm forms a coupling end. The coupling end is coupled to the coupling portion. The elastic clamp arm connects to the support arm and extends to the longitudinal arm. A front end of the elastic clamp arm engages the engagement flange. The elastic clamp arm penetrates the opening portion, moving elastically.
-
In view of the above structural design, the terminal structure is advantageously characterized by structural simplicity, ease of molding, low cost, and ease of assembly.
-
One of the coupling portion and the coupling end is a projecting coupling end. The other of the coupling portion and the coupling end is a coupling aperture. The projecting coupling end is inserted into the coupling opening.
-
The longitudinal arm comprises a surface. The surface faces the clamping element. On the surface a wavy strip is formed.
-
The cross arm bends down to form a leg.

Referring to 1 includes a terminal structure 1 a basic element 2 and a clamping element 3 , The basic element 2 is bent in an L-shape and includes a longitudinal arm 21 and a cross arm 22 that with the longitudinal arm 21 connected is. An upper end 211 of the longitudinal arm 21 forms an engagement flange 212 and an engaging shoulder portion 213 , A right end 221 of the cross arm 22 forms a coupling section 222 , The clamping element 3 includes an elastic clamp arm 31 , a support arm 32 and a connecting arm 33 , The connecting arm 33 forms an opening section 331 , The connecting arm 33 extends from the support arm 32 to the longitudinal arm 21 , The opening section 331 of the connecting arm 33 becomes the engaging shoulder portion 213 of the longitudinal arm 21 put around and engage with this. A lower end 321 of the support arm 32 forms a coupling end 322 , The coupling end 322 gets to the coupling section 222 of the cross arm 22 coupled. The elastic clamp arm 31 connects to the support arm 32 and extends to the longitudinal arm 21 , A front end 311 the elastic clamping arm 31 occurs with the engagement flange 212 of the longitudinal arm 21 engaged. The elastic clamp arm 31 penetrates the opening section 331 , in which he moves elastically.
