Description

Electric connector, circuit board mechanism and electronic equipment

Technical Field

The invention relates to an electric connector, a circuit board mechanism and an electronic device.

Background

With the increase of user demands, the functions of the current electronic devices are more and more, and along with this, more and more electronic components are integrated in the electronic devices. In view of the portability of electronic devices, the overall size of the electronic devices is generally small, and therefore, it is necessary to fully utilize the space in the electronic devices in order to achieve high integration of the electronic devices.

A ZIF (Zero Insertion Force) connector is a common electrical connector, and has the advantages of good mechanical performance, reliable electrical connection, low price, and the like, so that the connector is widely used in electronic devices. Referring to fig. 1 and 2, the current ZIF connector 101 is soldered on the circuit board 102 in a direction parallel to the circuit board 102, thereby electrically connecting the flexible circuit board 103 and the circuit board 102. The connector terminal 1011 of the ZIF connector 101 extends in a direction substantially parallel to the circuit board 102, and the connector terminal 1011 is provided with a fillet 1012 in accordance with the extending direction. This arrangement results in the ZIF connector 101 occupying a large area of the board surface on the circuit board, resulting in a low degree of integration of the circuit board. Under the circumstances, with the arrival of the 5G era, the internal space of the electronic device becomes more and more tense, and how to reduce the board surface area of the circuit board occupied by the ZIF connector is a problem to be solved urgently.

Of course, the above description has been made only by taking the ZIF connector as an example, and the problem of occupying a large area of the board surface of the circuit board 102 is also present in the case of other types of electrical connectors provided in parallel on the circuit board 102.

In one embodiment, the insulating base 100 is injection molded from a plastic material. Of course, the insulating base 100 may be made of other insulating materials, and the embodiment of the invention does not limit the specific material of the insulating base 100.

The connector terminal 200 is provided on the insulating base 100. Typically, there are at least two connector terminals 200, and at least two connector terminals 200 are typically fixed to the insulating base 100 in a side-by-side manner. In a specific embodiment, the number of the connector terminals 200 is at least three, and at least three connector terminals 200 are fixed on the insulation base 100 side by side and uniformly.

In this embodiment, one end of the connector terminal 200 is a solder leg, and the solder leg is used for being soldered to a circuit board (for example, a first circuit board 400 described later) in the electronic device, so as to achieve electrical connection between the electrical connector and the circuit board in the electronic device. The insulating base 100 includes a socket 111, and the other end of the connector terminal 200 protrudes into the socket 111 and is used for electrical connection with a second circuit board 300 described later. The electrical connector may achieve electrical connection between the second circuit board 300 and a circuit board (a first circuit board 400 described later) within the electronic device.

The connector terminal 200 is a long structural member, and in this embodiment, an end surface of the connector terminal 200 is a welding surface of the fillet.

In the electrical connector disclosed in the embodiment of the present invention, the structure of the connector terminal 200 is improved, so that the end surface of the connector terminal 200 is a welding surface of the solder leg, and thus the connector terminal 200 can be welded and fixed with the circuit board in the electronic device through the end surface of one end thereof, and the electrical connector can be perpendicular to the circuit board in the electronic device and stand on the circuit board, which can undoubtedly reduce the occupation of the area of the board surface of the circuit board. Therefore, the electric connector disclosed by the embodiment of the invention can solve the problem that the electric connector in the existing electronic equipment occupies larger area of the board surface of the circuit board.

The insulation base 100 provides a mounting base for the connector terminal 200, and the insulation base 100 has various structures, in a specific embodiment, the insulation base 100 may include a base body 110 and a cover 120, and the cover 120 may be detachably disposed on the base body 110. The connector terminal 200 may be sandwiched between the cover 120 and the base body 110, thereby achieving the fixed mounting of the connector terminal 200.
