Improved structure of terminal blocks

The present invention relates to an improved structure of a terminal, in particular to a terminal for connecting wires of an electronic component such as an LED, and particularly to a conductive clip which can block a wire from extending to a terminal, and smoothly insert the wire into the conductive clip. Improved structure of the frame jaws.

The terminal block, also called a connector, is mainly used to connect a metal wire (commonly known as a wire) between an electronic component and an electronic component, or to connect a wire between an electronic component and a circuit board, the electronic component including a resistor, a capacitor, an inductor, LEDs, transformers, liquid crystal panels, touch panels, etc., to transmit power or electronic signals to facilitate the installation and configuration of electronic products, electronic circuit boards and electronic components.

At present, there are many types of terminal blocks on the market. As shown in Fig. 1, the conventional terminal usually has an insulating case 1a and a conductive frame 2a covered in the insulating case 1a; the case 1a is generally made of plastic. The outer side of the outer casing 1a is provided with a wire opening 11a, and the top of the outer casing 1a is provided with an opening 12a; the frame 2a is mainly made of a conductive metal material, and the frame 2a includes an electrical connector exposed at the bottom of the outer casing 1a. 20a, and two elastic members 21a, 22a respectively disposed on two sides of the electrical connector 20a, the terminal can be electrically connected to the circuit board by the electrical connector 20a, and the elastic members 21a, 22a respectively extend toward the clamping portion 211a, 221a, and a pair of jaws 24a corresponding to the wire insertion opening 11a, and a notch 25a between the two clamping portions 211a, 221a and the clamping mouth 24a, and between the opening portions 12a, 221a The inner activity is set to correspond to the button 3a between the respective clip portions 211a, 221a. The outer wire can be inserted into the pinch 24a via the wire insertion opening 11a of the outer casing 1a, and the respective clamping portions 211a, 221a act on the clamping opening 24a to clamp the fixing wire; when the user presses the button 3a, the button 3a can push The jaw 24a is opened to release the wire from the pinch 24a.

However, when the wire enters the wire insertion opening 11a and is not inserted into the clamping opening 24a, the lower side of each of the elastic members 21a, 22a can be stopped by the electrical connecting member 20a, but the notch 25a above the two clamping portions 211a, 221a does not have any The structure of the wire is stopped, so that the wire easily passes through the notch 25a and protrudes beyond the conductive frame 2a, causing the wire to be separated from the pinch 24a, resulting in inconvenience in operation and prone to poor contact. Moreover, since the elastic members 21a, 22a and the electrical connector 20a are arranged in a U shape, in the case where the button 3a frequently pushes the respective clip portions 211a, 221a to open the jaw 24a, the elastic members 21a, 22a and the clip portion 211a, The 221a is easily deformed by the pressing of the button 3a, causing the jaw 24a to lose the effect of elastically holding the wire.

In addition, in order to support the button 3a elastically disposed in the opening 12a of the outer casing 1a, the frame 2a further includes a connecting member 23a extending from an elastic member 22a to the other elastic member 21a, and the connecting member 23a is provided with an extension The opening 12a spans the elastic arm 26a between the respective clip portions 211a, 221a, and the button 3a is provided at the end of the elastic arm 26a. Although the elastic arm 26a spans over the respective nips 211a, 221a, since the elastic arms 26a extend in the direction of the opening 12a, the elastic arms 26a are gradually separated from the notches 25a above the nips 211a, 221a of the elastic members 21a, 22a, thereby being elastic. The arm 26a still cannot stop the wire from extending beyond the conductive frame 2a; and, even if the elastic members 21a, 22a, the connecting member 23a and the electrical connector 20a are arranged in a square shape, the elastic members 21a, 22a and the connecting member 23a Not joined together, the elastic members 21a, 22a and the nip portions 211a, 221a are still easily pressed by the button 3a to be gradually deformed, and improvement is required.
