technical field

The invention relates to an electrical connector, in particular to a bidirectionally insertable electrical connector.

Background technique

In recent years, the rapid development of electronic technology has exceeded the imagination of the general public. Before many electronic devices are publicly listed, consumers often have no way of knowing what functions they have. Therefore, the role of consumer electronics producers has changed from supplying products according to market demand. , further promoted to the position of creating market demand. Even the launch of each generation of electronic devices has changed human social activities. For example, the popularization of smart phones with mobile Internet functions is the most obvious example of changing human social activities.

Consumers choose electronic devices not only because they have high-speed Internet access and multimedia playback functions, but because they can be thin, light and portable while having the aforementioned advantages. In addition to IC technology, the energy density of battery technology must be further improved to make electronic devices with functions similar to those of personal computers thin and portable. The so-called energy density is the amount of electricity that a battery can provide per unit volume or weight. Therefore, if the volume and weight of the battery can be reduced without reducing the capacity of the battery, the energy density of the battery can be effectively improved, and it is also helpful for its application in portable electronic devices. Lithium batteries are currently the most widely used power supply source for portable electronic devices.

As above, in order to reduce the size of portable electronic devices, there are currently operators who directly connect lithium batteries by welding (for example: spot welding impedance welding, ultrasonic wave, laser spot welding and conduction medium welding type electric welding, etc.) On the motherboard, that is, the lithium battery is changed from the original detachable type to the non-detachable type, and is directly built into the portable electronic device. However, although this method can reduce the volume of portable electronic devices, once a process defect occurs during the connection process, such as a defect in the lithium battery or the main board, it cannot be reworked according to the traditional design, resulting in the lithium battery and the main board must be connected at the same time. scrapped. Or, if the customer sends a defective product back to the factory for repair, and after inspection, it is found that only one of the lithium battery or the motherboard is defective, at this time, it will be limited by the traditional manufacturing method and cannot be reworked, resulting in lithium The battery and the motherboard must be discarded at the same time.

Therefore, using welding technology to connect the lithium battery and the circuit board has the problem that it cannot be reworked or is difficult to rework, and it is necessary to find an alternative solution to solve it.
