Description

electrical connector

【Technical field】

The utility model relates to an electric connector, in particular to an electric connector with a turning plate.

【Background technique】

Existing electrical connectors that can accommodate flexible printed circuit boards (FPC) generally include an insulating body, terminals held in the body, and a switch board assembled on the insulating body, as disclosed in Japanese Patent Application Publication No. 2004-63401 described electrical connectors. In the process of inserting the electrical connector into the FPC, the turning plate first moves horizontally outward for a certain distance before inserting into the FPC. After inserting the FPC, the turning plate rotates downward until it reaches the closed position. The FPC is electrically connected. Under vibration or other conditions, the transfer plate may move outward in the horizontal direction, thereby causing loose contact between the FPC and the electrical connector terminals, affecting the electrical connection between the electrical connector and the FPC.

Therefore, it is necessary to design an electrical connector that can overcome the above defects.

【Detailed ways】

Referring to FIG. 1 to FIG. 3 , the electrical connector 100 of the present invention includes an insulating body 1 , a plurality of terminals 2 , 3 and a switching plate 4 . The insulating body 1 is elongated, and its front face is concavely provided with a socket 10 that can be inserted into the FPC 5 (as shown in Figure 5 ). A supporting surface 110 is formed on the bottom surface of the space, and a group of terminal receiving grooves 12 arranged along the longitudinal direction of the insulating body penetrate through the front and rear end surfaces of the insulating body. Stoppers 14 are provided at the bottom of both ends of the receiving space 11 , and stoppers 13 are arranged above the stoppers.

Please refer to Figures 3 to 5, several terminals include a first terminal 2 and a second terminal 3, wherein the first terminal 2 is inserted into the terminal receiving groove 12 of the insulating body 1 from the rear end surface of the insulating body 1, and the second terminal 3 is self-insulating The front end of the main body 1 is inserted into the terminal accommodating groove 12 , and is fixed in the insulating main body 1 in an alternate arrangement. Both the first and second terminals are in the shape of an "I", and their structures and assembly methods are similar. Therefore, the following mainly introduces the first terminal 2. The first terminal 2 includes a fulcrum portion 20 and an upper arm 21 and a lower arm 22 located on two sides of the fulcrum portion and extending in parallel. The upper and lower arms on the left side of the fulcrum part 20 (that is, the side close to the socket 10) form the upper contact arm 210 and the lower contact arm 220; 211, the end of which is provided with a hook-shaped pivoting portion 212, and the lower arm extends out of the insulating body to form a soldering foot 221 that can be soldered on the circuit board. Since the second terminal 3 is inserted into the insulating body 1 from the front surface of the insulating body 1 , its soldering foot 321 is formed by extending out of the insulating body 1 from the lower arm near the socket 10 .

The turning and pressing plate 4 is a long plate, and along its longitudinal side, there are a plurality of partitions 42 spaced apart by slots 41. A pivot 43 is arranged in the slot 41, and the pivot 43 is a cam shape in this embodiment. The turning plate 4 is pressed into the pivoting parts 212 and 312 of the first and second terminals from the back end of the insulating body 1 , and its pivot 43 is hooked by the pivoting parts, so that the turning plate 4 is assembled on the insulating body 1 . FIG. 4 shows the state when the turn-press plate 4 is in an open state, the terminals 2 and 3 are in a free state, and the partition plate 42 abuts against the supporting surface 110 of the insulating body 1 . The long axis of the pivot 43 is parallel to the upper and lower arms 21, 22 of the terminal. After the FPC 5 is inserted into the socket 10, the turning plate 4 rotates toward the support surface 110 of the insulating body, and the long axis of the pivot 43 rotates to be on the terminal. , the direction perpendicular to the lower arms 21, 22, as shown in Figure 5, it can press the pivot part 212 of the terminal upward, and the contact part 210 located at the opposite end of the pivot part moves downward with respect to the fulcrum part 20, which can resist Push down the FPC 5, that is, the turn-press plate 4 is in the closed state.

Referring to Fig. 3, end shafts 44 are also provided at both ends of the turning plate 4 along the longitudinal direction. After the turning plate 4 is assembled in the insulating body, the end shafts 44 are accommodated in the space formed by the stopper 13 and the stopper 14. . Fig. 6 is a partially enlarged view of the assembly of the turning plate 4 on the rear end shaft 44 of the insulating body 1 and the insulating body 1. The stopper 13 can further prevent the turning plate 4 from detaching from the insulating body 1 during the rotation process, and the shafts 44 at both ends It is in the shape of a cam, and its outer circumference further protrudes outward along the direction perpendicular to the axial direction of the end shaft 44 to form an arc-shaped protruding portion 441 . The function of the protruding portion 441 will be described in detail below.

7 to 9 show the process of cooperation between the shafts 44 at both ends of the turning plate 4 and the insulating body 1 from the open state to the closed position. As shown in FIG. 7 , the inner side of the stopper 14 has a downwardly inclined interference surface 141 , and the junction 142 between the stopper 14 and the interference surface 141 has the closest distance to the end shaft 44 . When the turning plate 4 is in the open position, the terminal is in a free state as shown in FIG. 4 , and the shafts 44 at both ends are spaced from the interference surface 141 on the insulating body 1 by a certain distance, as shown in FIG. 7 as T. When the turning pressure plate 4 is rotated downward by external force, the turning pressure plate 4 rotates in the direction of arrow A, and the end shaft 44 must be subjected to an outward force (that is, to the left side of the drawing), because there is a distance between the interference surface 141 and the end shaft , the end shaft 44 has a tendency to move outward due to the outward force. When the turn plate 4 rotates at a certain angle, the protruding part 441 of the end shaft 44 will abut against the interference surface 141. At this time, the interference surface 141 will provide the protruding part 441 with an upward and right force, as shown in FIG. It can prevent the turning press plate 4 from moving in the direction opposite to F2, thereby preventing the turning press plate 4 from detaching. After the protruding portion 441 passes over the interference surface 141 , there is a certain distance between the interference surface 141 and the protruding portion 441 as shown in FIG. Similarly, to take out the FPC5, use external force to rotate the turning plate 4 upwards. At the same time, if the electrical connector 100 is subjected to vibration or other non-human external force, when the turning plate 4 rotates upwards slightly, the protruding portion 441 of the end shaft 44 will interfere with the interference surface 141, thereby preventing the turning plate 4 from continuing to rotate upwards. Prevent turning pressure plate 4 from opening accidentally.

The utility model is not limited to the above-mentioned embodiments. The force F2 generated by the interference between the protruding portion 441 and the interference surface 141 can prevent the turning plate 4 from detaching in the horizontal direction, so the terminal pivoting portion can also be straight rod-shaped, The interference surface 141 can also be an arc surface.
