Description

Connecting structure of alternating current plug pin and electric wire

[ technical field ] A method for producing a semiconductor device

The utility model relates to a connection structure of alternating current plug foot and electric wire.

[ background of the invention ]

As shown in fig. 1, the mobile phone charger generally has a plastic housing, which is composed of two parts: a cover 1a and a housing 2a, the plastic housing also containing a PCB assembly containing electronic components. The cover has pins 3a which are ac input pins for insertion into an ac outlet. One of the most common ways of connecting ac pins to the PCB assembly is via a wire 4 a. One end of the wire is connected to the PCB assembly and the other conductor end 5a is connected to the end of the prong inside the charger. The most common method of connecting the pins to the wires is to connect the wires to the pins by crimping, soldering or welding, as shown in figure 2 for a crimped configuration, by providing slots 7a at the inner end of the pins 3a that mate with the conductor ends 5a, closing the slots by stamping to press the conductor ends 5a into a secure connection, and then applying glue 6a to secure the wires to the cover, to improve mechanical safety to meet safety requirements, as shown in figure 3. In addition to glue bonding, other methods may be used, such as tape bonding or hot melt. Gluing is the preferred method because it is a faster process. Whichever method is used, a second process is required to secure the wires to the cover to increase mechanical safety.

The current common methods require two steps to complete the connection of the wires to the pins:

1. fixing the conductor part of the lead on the pin;

2. the wires are fixed to the cover with glue to improve mechanical safety.

They all have the same disadvantages:

longer processing time;

the assembly cost is high since more processes are required;

materials such as glue, adhesive tape and the like are used, so that the material cost is high;

the more process steps involved in assembly production, the more susceptible the product is to quality problems.

To avoid the above problems, it is critical to secure the wires to the pins in a single process without the use of glue. The present invention has been made in view of the above problems.

The present invention provides an alternative method for pin to wire connection that requires only a single step process and does not require additional materials such as glue.
