1. Field of the Invention
The present invention relates to an electrical connector, and particularly to an electrical connector having an improved terminal block.
2. Description of the Prior Art
With the rapid development of the technology of wireless communication and advanced technology of electrics, electronic consuming products such as mobile phone, Personal Digital Assistant (PDA) etc., are designed to comply with miniaturization trend and multiple functions to meet with requirements of human. As a result, the requirements of elements, such as terminals and terminal block, used in such equipments are correspondingly go along with the trend of miniaturization. It will cause great difficulties in the process of assembly.
Please refer to
Hence, an improved electrical connector is desired to overcome the disadvantages of the prior art.
Therefore, a main object of the present invention is to provide an electrical connector having an improved terminal block.
To fulfill the above-mentioned object, An electrical connector comprises a terminal block and a plurality of terminals. The terminal block comprises an inner wall, an outer wall opposite to the inner wall and a plurality of receiving slots defined between the inner wall and the outer wall for receiving terminals. A plurality of terminals are assembled to the receiving slots of the terminal block and each terminal has a contacting portion, a soldering portion and a base portion connecting with the contacting portion and the soldering portion. Wherein each receiving slot further defines a projecting board extending from the inner wall, a supporting portion forming on the top of the outer wall and a channel defined between the projecting board and the supporting portion, the projecting board and the supporting portion respectively support two sides of the base portion of the terminal.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The foregoing summary, as well as the following detailed description of the embodiments of the present invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there are shown in the drawings embodiments which are presently preferred. As should be understood, however, the invention is not limited to the precise arrangements and instrumentalities shown. In the drawings:
Reference will now be made in detail to the preferred embodiment of the present invention.
Referring to
The terminal block 1 dimensioned to ring shape comprises an inner wall 11, an outer wall 12 opposite to the inner wall 11 and a plurality of receiving slots 10 defined between the inner wall 11 and the outer wall 12 and arranged in a circumferential direction for receiving terminals 2. Each receiving slot 10 forms a projecting board 101 horizontally extending from the inner wall 11 to the outer wall 12, a supporting portion 103 defined on the upper surface of the outer wall 12 and corresponding to the projecting board 101 and a channel 102 penetrating the terminal block 1 between the inner wall 11 and the outer wall 12. The projecting board 101 and the inner wall 11 are separated at a certain distance by the channel 102. The top surfaces of the supporting portion 103 and the projecting board 101 are substantially located in the same plane, and the supporting portion 103 further defines a retaining groove 120 corresponding to the projecting board 101.
