Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many different forms other than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention, and it is therefore not to be limited to the specific embodiments disclosed below.

As shown in fig. 3 to 5, which disclose the structure of the preferred embodiment of the present invention, an electrical connector 10 includes: the connector comprises an insulating base body 11 and a plurality of conductive terminals 12 fixed on the insulating base body 11 at a preset interval. Of course, to ensure the function of the structure, the electrical connector 10 further includes a metal shell 13 for grounding the shield or increasing the retention force of the solder to the circuit board.

The insulating substrate 11 is made of a resin material, such as LCP, and has a substantially rectangular parallelepiped shape. The conductive terminals 12 are fixed on the insulating base 11 by an insert-molding (insert-molding) process.

The conductive terminal 12 is formed by stamping, blanking, bending and molding a sheet metal material, and includes a first section 121 and a second section 122, the first section 121 is n-shaped, the second section 122 is in a straight shape, one end of the first section 121 is connected to the second section 122, and a free end of the other end of the first section 121 is bent to form a bent portion 1211, as shown in fig. 5, the bent portion 1211 is an inner bent structure bent from the free end of the first section 121 toward an end connected to the second section 122, which has the advantage of saving a space occupied by the first section 121.

Further, the two side edges of the bending portion 1211 are symmetrically disposed with the barbed portions 1211a, in other embodiments, the barbed portions 1211a may be disposed on only one side of the bending portion 1211, as long as the structural strength is ensured to be reasonable.

Through the arrangement, the conductive terminals 12 are embedded in the insulating base 11 after insert-molding (as shown in fig. 4), so that the bonding force between the conductive terminals 12 and the insulating base 11 is greatly enhanced, and the conductive terminals 12 can be effectively prevented from being separated from the insulating base 11 due to excessive pulling force while the conductive terminals are pulled out after being buckled with corresponding counterpart terminals (not shown in the figure) of a counterpart connector, thereby reducing the risk of breaking the conductive terminals 12 due to repeated pulling and inserting.

It should be noted that the conductive terminal 12 of the present invention maintains the original space size of the conventional conductive terminal shown in fig. 2, and only needs to add the design of the inward-folded bending portion 1211 and the barb portion 1211a on the basis of the U-shaped bending of the conventional conductive terminal, thereby achieving the technical objective, and the conductive terminal is simple in structure and easy to manufacture.

The utility model also provides an electric connector assembly, including foretell electric connector 10 with rather than the other side connector (not shown in the figure) that the cooperation was used of inserting, this kind of electric connector assembly can not take place the bad problem that conductive terminal deviates from easily on the insulating base member at mutual plug in-process, and the reliability is high.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
