Electrical connectors provide electrical connections between different electronic systems through conductive terminals. As an example of a possible application, an analog user test platform used in the semiconductor industry for testing chips requires the use of a standard test interface (STHI) Communications Interface Board (CIB) card, which is a signal transport card.
Fig. 1 schematically shows such a communication interface board 1, and fig. 2 is an exploded perspective view of the communication interface board shown in fig. 1. As shown in fig. 1 and 2, the communication interface card includes a printed circuit board 3 and an electrical connector 5 mounted on the printed circuit board 3. The electrical connector 5 includes a plurality of lead frame assemblies 7 each having at least one column of conductive terminals 9 aligned with one another, the mounting ends of each of which are mounted to the printed circuit board 3, such as by soldering or other known connection means, such that the plurality of lead frame assemblies 7 are mounted side-by-side to the printed circuit board 3. The electrical connector 5 is a right angle connector with the mounting and mating ends of the conductive terminals in a plane at substantially 90 degrees to each other, although the electrical connector 5 may be a vertical connector with the mounting and mating ends of the conductive terminals in substantially parallel planes to each other. The plurality of lead frame assemblies 7 mounted side by side on the printed circuit board 3 are not stable and are extremely susceptible to damage, and therefore the plurality of lead frame assemblies 7 are usually held together by a holder 11 to prevent the lead frame assemblies from being damaged as much as possible. The holder 11 is substantially in the shape of an L-shaped thin plate, and the holder 11 is formed at the front end thereof with a plurality of teeth 13 and at the body thereof with a plurality of penetrating slots 15. The holder 11 may hold the plurality of lead frame assemblies 7 firmly in place by inserting the teeth 13 of the holder 11 into the grooves or recesses 17 on the housing of the respective lead frame assembly 7 and engaging the protrusions on the housing of the respective lead frame assembly 7 into the corresponding through slots 15 of the holder 11. Through multiple plugging and unplugging, when the electrical connector 5 is matched with a corresponding male connector, one or more lead frame assemblies may be bent, deformed or damaged, so that the entire electrical connector and further the communication interface board card may fail and be unusable. Before the lead frame assembly, which is deformed by bending or damaged, is repaired or replaced, the holder 11 needs to be pulled out from the plurality of lead frame assemblies. If the holder 11 is pulled out from the plurality of lead frame assemblies by direct force, it is extremely easy to cause the lead frame assemblies made of insulating material to be damaged. In practice, the entire communication interface board usually has to be sent to the manufacturer for maintenance, which is time-consuming, labor-consuming and extremely expensive.
To this end, a device for removing an electrical connector is needed that removes a holder from a plurality of lead frame assemblies of the electrical connector.
