Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a type of electrical connector assembly, and more particularly to an electrical connector assembly which stably and electrically connects two circuit boards and has a function of grounding.

[0002]

BACKGROUND OF THE INVENTION Conventional board-to-board electrical connectors include a plug and a receptacle. The plug and the receptacle are fixed to the interface board and the circuit board, respectively, and the plug and the receptacle are inserted into and engaged with each other to electrically connect the interface board and the circuit board. The prior art is characterized by the stability of the contact between the plug of the connector and the receptacle, but neglects the stability after the plug and the receptacle terminal are connected and the result of the failure due to the mechanism design.

[Patent Document 1] Taiwan utility model registration application No. 882223
No. 62 bulletin

The plug and the receptacle of the board-to-board type connector are fixed to the interface board and the circuit board, respectively, and the positioning groove is provided in the plug, and the notch is formed from one side of the positioning groove to the outside of the positioning groove. To form. A frame groove is installed in the receptacle, and a protrusion and a wide portion for engaging with the notches of the positioning groove are provided at both ends of the frame groove, thereby locking the plug and the receptacle in a certain direction. The electrical connection between the plug and the receptacle can be made stable while the electrical connection is established.

[0005]

However, since the board-to-board type connector is not provided with a locking device in the inserting direction of the electrical connector after the plug and the receptacle are brought into contact with each other, the plug and the receptacle are not connected to each other. The electric connector can be moved oppositely in the inserting direction, and therefore has the following two drawbacks. 1. In the conductive terminal, the plug and the receptacle move along the inserting direction, so that the conductive performance of the terminal becomes unstable. 2. Due to the non-uniform contact pressure between the terminals or the uneven contact area, the conductive performance of the electrical connector is unstable.

The present invention ensures the effect that each abutting connector is stably inserted and has a ground connection function, and improves the overall mechanical and electrical performance of the electrical connector assembly. The purpose is to provide.

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, an electric connector assembly 1 according to the present invention includes a first connector 2 and a second connector 4. The first connector 2 has a first terminal 22 and a first insulating body 21 that accommodates the first terminal 22, and the first insulating body 21 has first ear portions 211 from both ends in the longitudinal direction.
The first inner wall 2113 and the first side surface 2111 perpendicular to the first inner wall are provided on the first ear portion 211.
11, the first side wall 2111 extends in a direction perpendicular to the first side wall 2111.
A flange 2112 is provided, and a first housing cavity 2114 is formed between the first flange 2112 and the first inner wall 2113.

The first elastic piece 3 is attached to the first ear portion 211 of the first connector 2 and is provided with the first base portion 31. The first base portion 31 is used for positioning the first elastic piece.
Is accommodated in the first accommodation cavity. From the flat short side ends of the first base portion 31, the first bending portion 32 and the first elastic portion 3 are provided.
3 is extended and fixedly locked to the first ear portion 211 of the first connector 2, the first locking piece 321 is curved and extended from both flat longitudinal end portions of the first bending portion 32. . Thereby, the first elastic piece 3 is completely fixed to the first ear portion,
In addition, the semi-cylindrical arcuate protrusion 331 is installed on the first elastic portion 33.

The second connector 4 can contact the first connector 2 and has a second terminal 42 and a second insulating body 41 for accommodating the second terminal 42. Both ends of the second insulating body 41 in the longitudinal direction. The second ear portion 411 extends from the second inner wall 4113 and the second side surface 411 perpendicular to the second inner wall 4113.
1 is provided, and the second side wall 411 is provided on the second side surface 4111.
A second flange 4112 extending perpendicularly to the first flange 4112 is installed, and a second housing cavity 4114 is formed between the second flange 4112 and the second inner wall 4113.

The second elastic piece 5 is attached to the second ear portion 411 of the second connector 4 and is provided with the second base portion 51.
The second base 51 is housed in the second housing cavity 4114 for positioning. The second curved portion 52 and the second elastic portion 53 extend from both ends of the second base portion 51 in the flat lateral direction, and are firmly locked to the second ear portion 411 of the second connector 4, so that the second curved portion is formed. The second locking pieces 521 are curvedly extended from both flat end portions of the 52 in the longitudinal direction. At this time, the second elastic piece 5 is completely fixed to the second ear portion 411, and the second elastic portion 53 is provided with a rectangular locking groove 531 for engaging with the arc-shaped projection 331.

Please refer to FIG. First connector and second
Before the connector is inserted, first the first elastic piece 3
The base 31 has the first housing cavity 211 of the first ear 211.
4, the first locking piece 321 presses the first side surface to position and fix the first elastic piece. Similarly, the second locking piece 521 positions and fixes the second elastic piece 5. When inserting the second connector 4 into the first connector 2, after the first elastic portion 33 comes into contact with the second elastic portion 53,
The arcuate protrusion 331 presses the second elastic portion 53 so that the first elastic portion 33 and the second elastic portion 53 are elastically deformed, and the arcuate protrusion 331 and the locking groove 531 are engaged with each other. After being stopped, the first elastic portion 33 and the second elastic portion 53 recover elastic deformation to ensure that the arcuate projection 331 and the locking groove 531 are completely locked and connected.

Therefore, the present invention can overcome the problem that the movement of the first connector 2 with the second connector 4 along the insertion direction and the contact of the terminals due to the movement is bad. In addition, by electrically connecting the first ear portion 211, the second ear portion 411, the first elastic piece 3 and the second elastic piece 5 of the present invention (as shown in FIG. 3), the electrical connector assembly 1 Will be able to provide the function of earth connection.

The above embodiment is merely a better embodiment of the present invention, and any modification or alteration of details that those who are familiar with the technology of the present invention can make based on the present invention are also included in the present invention. Of the claims.
