Description

Electrical connector with pick-and-place plate and method for installing pick-and-place plate on electrical connector

【Technical field】

The invention relates to an electrical connector with a pick-and-place board and a method for installing the pick-and-place board on the electrical connector, in particular to an electrical connector with a pick-and-place board that can be sucked by a vacuum suction device and A method of mounting a pick and place plate on an electrical connector.

【Background technique】

In the process of soldering the electrical connector on the circuit board, a vacuum suction device is generally used in the industry to absorb the electrical connector so as to effectively locate it on the circuit board by mechanical operation. However, since the electrical connector is not provided with a smooth plane that can be sucked by the vacuum suction device, the suction operation is usually completed by means of a pick-and-place device installed on the socket connector. For example, US Patent No. 6,413,111 published on July 2, 2002 discloses an electrical connector with a pick-and-place device.

At present, a pick-and-place device for electrical connectors is commonly used in the electrical connector industry. As shown in FIGS. Two opposite ends of the first extension part 92 and the second extension part 93 extend outward respectively, and the first extension part 92 and the second extension part 93 are respectively provided with two relatively parallel first contact arms 920 and second contact arms 930 The two opposite first contact arms 920 are connected to a connecting portion 921 at one end away from the base portion 91, and the two opposite first contact arms 920 are bent vertically downward near the connecting portion 921 to form a first engaging portion 922. The engaging portion 922 is connected with a first engaging arm 923 perpendicular to it, and a first engaging groove 924 is formed between the two first engaging portions 922 and the first engaging arm 923, and the two opposite second contact arms One end of the 930 away from the base 91 is respectively bent vertically downward to form a second engaging portion 931, the two second engaging portions 931 are connected with a second engaging arm 932, and the two second engaging portions 931 are engaged with the second engaging portion 931. A second engaging groove 933 is also formed between the arms 932 . The electrical connector 8 used in conjunction with the pick-and-place device 9 is installed on a circuit board (not shown), which includes an insulating body 80 and a conductive terminal 81 accommodated in the insulating body 80, and the corresponding pick-and-place device 9 on the insulating body 80 The first and second engaging arms 923 and 932 on the first and second extension parts 92 and 93 respectively have protruding hooks 800 . When the pick-and-place device 9 is combined with the electrical connector 8, press down hard to deform the first engaging portion 922 and the second engaging portion 931 respectively, so that the first and second clamps of the pick-and-place device 9 The engaging slots 924 and 933 respectively engage with the protruding hooks 800 of the insulating body 80 , thereby fixing the pick-and-place device 9 to the electrical connector 8 . At this time, the vacuum suction device (not shown) sucks the smooth area on the surface of the base 91 of the pick-and-place device 9 to effectively position the electrical connector 8 on the circuit board (not shown) by mechanical operation.

Due to the interfering engagement between the pick-and-place device 9 and the electrical connector 8 by the first and second engagement grooves 924, 933 respectively interfering with the protruding hook 800, the fastening effect between the pick-and-place device 9 and the electrical connector 8 is achieved. , so when the pick-and-place device 9 is removed from the electrical connector 8, the normal direction of force application is an oblique upward detachment force F as shown in Figure 2, and its horizontal component force Fx will make the pick-and-place device 9 and the electrical connector The insulating bodies 80 of the connector 8 are more tightly matched, so that the pull-out force for pulling out the pick-and-place device 9 is increased, making it difficult to pull out the pick-and-place device 9, and the removal force F needs to be applied to the pick-and-place device 9 by the operator The end of the extended part, that is, the edge position of the electrical connector 8, when the circuit board (not shown) on which the electrical connector 8 is installed is provided with many parts around the electrical connector 8, the operator's fingers will not be able to Get a larger operating space. Therefore, it is necessary to design a new pick-and-place device for electrical connectors to overcome the above disadvantages.

In addition, from the above description of the prior art, it can be seen that the process of installing the pick-and-place device 9 on the electrical connector 8 is: first place the pick-and-place device 9 on the corresponding position on the electrical connector 8 from top to bottom, and then Press down the pick-and-place device 9 to deform the first engaging part 922 and the second engaging part 931 respectively, so that the first and second engaging grooves 924 and 933 are respectively aligned with the corresponding protruding hooks 800 of the insulating body 80 to achieve reliable cooperation between the pick-and-place device 9 and the electrical connector 8 . However, the pressing down process during installation may cause damage to the engaging portion, and it is not easy to remove the pick-and-place device 9 from the electrical connector 8 during disassembly. Therefore, while providing a new type of electrical connector, the present invention also introduces a method for installing the pick-and-place device on the electrical connector, so as to solve the damage and disassembly of the engaging part of the pick-and-place device caused by the assembly process. difficult question.
