Description

Electrical connector

The invention relates to a single-row board-to-board electrical connector, in particular to a conductive terminal integrally formed in an insulating body.

For a prior art related to the present invention, see U.S. Patent Publication No. US20130149908. The disclosed patent discloses a single-row board-to-board electrical connector including an insulative housing, a plurality of conductive terminals mounted on the insulative housing, the insulative housing having a plurality of terminal slots, the conductive terminals being assembled in the terminal slots However, the structure in which the conductive terminals are assembled in the insulating body in this way makes the insulating body not strong enough, and the conductive terminals are easily loosened.

Therefore, it is necessary to design a new type of single-row board-to-board electrical connector to solve the above technical problems.

The technical problem to be solved by the present invention is to provide a single-row board-to-board electrical connector, which is integrally formed with a conductive terminal by a two-molding method.

In order to solve the above technical problem, the present invention adopts the following technical solutions: An electrical connector includes an insulative housing and a plurality of conductive terminals received in the insulative housing, the insulative housing including a first molding portion and a second molding portion. The first molding portion includes a first sidewall and a second sidewall. The first sidewall is provided with a plurality of terminal slots. The conductive terminal includes an elastic contact portion received in the terminal slot and bypasses the elastic contact portion. a holding portion extending downward from the second side wall and a welded portion extending from the holding portion, wherein the second molding portion is overmolded on the second side wall of the first molding portion.

Compared with the prior art, the conductive terminals of the electrical connector of the present invention are integrally formed in the insulating body, so that the structure of the entire electrical connector is stronger and the conductive terminals are stably held.

The first figure is a perspective view of the same two board-to-board electrical connectors of the present invention.

The second figure is a perspective view of the separation of the same two board-to-board electrical connectors of the present invention.

The third figure is an exploded view of the electrical connector of the present invention.

The fourth figure is a flow chart for integrally forming the insulating body of the electrical connector of the present invention and the conductive terminals.

The fifth figure is a cross-sectional view in the V-V direction when the same two board-to-board electrical connectors shown in the first figure are mated with each other.

Referring to the first figure, an electrical connector assembly 200 includes two identical male and female common board-to-board electrical connectors 100.

Referring to the second to fourth figures, the electrical connector 100 includes an insulative housing 10 having a substantially rectangular parallelepiped shape, a plurality of conductive terminals 20 received in the insulative housing 10, and solder terminals 30 integrally formed in the insulative housing 10. The solder terminal 30 allows the entire electrical connector 100 to be more stably soldered to an external circuit board (not shown).

The insulative housing 10 includes a first molding portion 11 and a second molding portion 12, and the first molding portion 11 includes a first sidewall 111, a second sidewall 112, and a first sidewall 111 and a second sidewall 112. The bottom wall 113 is provided with a plurality of terminal slots 110 extending from the first side wall 111 to the boundary between the bottom wall 113 and the second side wall 112. The bottom wall 113 is located on the bottom wall 113. The terminal groove 110 penetrates the bottom wall 113. The conductive terminal 20 is mounted in the terminal slot 110. The conductive terminal 20 includes an elastic contact portion 21 received in the terminal slot 110 of the first sidewall 111, and extends horizontally from the elastic contact portion 21 and is received in the bottom wall 113. The horizontal portion 22 in the terminal slot 110 extends from the horizontal portion 22 upwardly around the second side wall 112 and the solder portion 24 extending horizontally outward from the holding portion 23, so that the electrical connector 100 is horizontally soldered On the board (not shown).

After the conductive terminal 20 is mounted on the terminal groove 110 of the first molding portion 11, a second injection molding is performed, and the second molding portion 12 is wrapped around the second sidewall 112 of the first molding portion 11. At the same time, the holding portion 23 of the conductive terminal 20 from the horizontal portion 22 is insert-molded into the second molding portion 12, so that the conductive terminal 20 is integrally formed in the insulating body 10, so that the structure of the entire electrical connector 100 is stronger. . The holding portion 23 of the conductive terminal 20 embedded in the second molding portion 12 is provided with a contact surface 230 exposed to the air, and the contact surface 230 extends from one side of the second side wall 112 to the other side. When mated with the mating connector 100, the contact surface 230 is electrically connected to the conductive terminal 20 of the mating connector 100.

Referring to the fifth figure, a receiving space 114 is formed between the first sidewall 111, the second molding portion 12 and the bottom wall 113. When the two electrical connectors 100 are mated, the second sidewall 112 is second. The molding portion 12 and the holding portion 23 of the conductive terminal 20 are collectively housed in the accommodation space 114 of the other party. As can be seen from the figure, the inner conductive portions 23 of the two conductive terminals 20 are in surface contact with each other, and the upper end of the elastic contact portion 21 of the conductive terminal 20 is inclined toward the holding portion 23 and the first convex portion is provided at the end of the elastic contact portion 21. When the mating connector is inserted into the receiving space 114, the elastic contact portion 21 of the conductive terminal 20 better grips the mating connector 100, and the first protruding portion 210 is electrically connected to the mating connector 100. Contact is more stable. A second protrusion 231 is disposed on a side of the holding portion 23 away from the first sidewall 111, and the first protrusion 210 slides through the second protrusion 231 to electrically contact the butted conductive terminal 20, such that The design makes it difficult for the two conductive terminals 20 to fall off when they are mated.

Compared with the prior art, the conductive terminal 20 of the electrical connector 100 of the present invention is integrally formed in the insulative housing 10, so that the structure of the entire electrical connector 100 is more robust, and the conductive terminal 20 is stably held.
