Electric connector and LED lamp thereof

Technical Field

The utility model relates to the technical field of electrical devices, in particular to an electrical connector and an LED lamp thereof.

Background

In the conventional electrical connector, generally, the shell of the terminal is opened, the external conductor is fixedly connected with the conductive element in the terminal by using the connecting piece or the fixing piece, and then the shell is closed to connect the conductor to the connector.

In order to avoid the above problems, the electrical connectors that are currently marketed achieve a quick-insertion connection between conductors that are mated to different terminals by detachably engaging male and female terminals with each other. The butt joint mode between the conductors is simplified, and the conductor splicing operation is more convenient. However, the applicant has found that, with a male-female butt connection, which is convenient, the fitting of the internal conductive element is more cumbersome, making the assembly of the conductive element inconvenient and considerably reducing the wire clamping effect. The contact tightness of the conductive element in the terminal is poor, so that the electric connection is unstable and the reliability is poor. In addition, the loose phenomenon of the installation and the positioning of the conductive element in the terminal is inevitably easy to occur, and the connection operation of the conductor and the terminal is directly influenced.

A first connection opening 14 disposed opposite to the first wire opening 13 is defined in the other outer end side of the male terminal 1, and is detachably joined to the female terminal 2 through the first connection opening 14. It is particularly important that the first electrical connector 11 and the first elastic member 12 are separated from each other, such that the first elastic member 12 is configured to pass through the first wire opening 13 and be installed and limited in the terminal, the first electrical connector 11 is configured to pass through the first opening and be stably installed in an installation position in the terminal, and a clamping opening capable of elastically clamping a conductor is defined between the first elastic member 12 and the first electrical connector 11.

This arrangement ensures that the two conductive elements in the male terminal 1 are arranged in a detachable manner in horizontally different directions, so that the manner of assembly of the first electrical connector 11 can be highly adapted to the insertion and extraction operations of the conductors in the terminal. Specifically, when the conductor is inserted into the first wire opening 13 side, the first electrical connector 11 receives a pushing force in the insertion direction, and is more easily mechanically and electrically contact-fitted with the conductive member in the female terminal 2. And, when the conductor is pulled out at the first wire opening 13 side, the first electric connector 11 is subjected to a pulling force in a pulling direction which coincides with the assembling direction of the first electric connector 11, so that the first electric connector 11 is further mounted in place so as to be stably confined in the mounted position, the movement of the first electric connector 11 can be effectively prevented from being disengaged, and the formed jaw elastic force is kept stable correspondingly.

Specifically, the first elastic element 12 is formed in a triangular shape with a notch 124 and is bent integrally, the elastic arm 121 and the position-limiting arm 122 are connected by a connecting arm 123, and the notch 124 is formed by the inner end side of the elastic arm 121 and the position-limiting arm 122 facing each other, so as to allow the elastic arm 121 to perform elastic deformation only in the path of the notch 124, thereby preventing the elastic arm 121 from elastic failure. The outer end side of the elastic arm 121 faces the first electrical connector 11 to form the nip, and the elastic arm 121 is obliquely abutted against the connecting arm 123 and is supported and fitted by the connecting arm 123 with the elastic force of the elastic arm 121. In addition, the first elastic part 12 in a triangular shape is arranged on one side of the first installation cavity 15, the first electrical connector 11 in a strip shape is oppositely arranged on the other side of the first installation cavity 15, so that a clamping opening with elastic force is formed in a matched mode, the external conductors are respectively clamped between two independent elements, and the elastic clamping effect is particularly remarkable.
