Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the description herein. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways. Various modifications and changes may be made in the details within the description and the drawings without departing from the spirit of the invention.

Referring to fig. 1 to fig. 11 in the drawings, the following embodiments are described together to explain the technical idea of the wire-to-board connector of the present invention:

referring to fig. 1 to 11, a wire-to-board connector 1 according to the present invention is used to electrically connect wires 2 for transmitting electrical signals. When the wire-to-board connector 1 is operated, the electrical connection to the circuit board 3 can be completed or released in the first operation state and the second operation state, respectively.

The wire-to-board connector 1 includes conductive terminals 11 and an insulating housing 12.

In the present invention, the conductive terminal 11 has the connecting end 111 and the soldering end 112, and the conductive terminal 11 is, for example, an elastic cantilever and can be deformed by a force to be in the first shape as shown in fig. 9 or the second shape as shown in fig. 4. As shown in fig. 9 and 11, when the conductive terminal 11 is in the first shape, a portion of the connecting end 111 is inserted into the deformation space 123, so that the connecting end 111 is adapted to the displacement of the circuit board 3 to complete the electrical connection of the circuit board 3.

It should be noted that, the wire-to-board connector 1 may optionally have a plurality of conductive terminals 11 according to the application requirement. Even more, the wire-to-board connector 1 can be selected to have a plurality of conductive terminals 11 with different structures for transmitting different electrical signals respectively.

In the present invention, one of the functions of the insulating base 12 is to position the conductive terminal 11, and the inserting operation structure 121 and the welding operation structure 122 are formed on the insulating base 12. The plugging structure 121 is, for example, a jack for the circuit board 3 to perform plugging operation, so that the circuit board 3 can be plugged into the insulating base 12, and the soldering structure 122 is, for example, a groove for exposing the soldering terminal 112, so as to perform soldering operation on the soldering terminal 112, and solder the wire 2 to the soldering terminal 112, thereby completing the electrical connection of the conductive terminal 11 to the wire 2.

It should be noted that, because the conductive terminals 11 of the wire-to-board connector 1 of the present invention are electrically connected to the wires 2 by welding, the conductive terminals 11 can be positioned on the insulating base 12 and then the wires 2 are welded by the welding operation structure 122 of the insulating base 12, so that the conductive terminals 11 do not need to be electrically connected to the wires 2 in the manufacturing process of the wire-to-board connector 1, and the manufacturing procedure of the wire-to-board connector 1 can be simplified, and moreover, the conductive terminals 11 do not need to be additionally provided with a structure for electrically overlapping the wires 2 (e.g., a wire clamping structure for clamping the wires), so that the volume of the conductive terminals 11 can be reduced, and further the size of the wire-to-board connector 1 can be reduced.

In the wire-to-board connector 1 of the present invention, when in the first operating state, the circuit board 3 is inserted into the insulating housing 12, and the conductive terminals 11 are forced to be in the first shape as shown in fig. 9, so that the connecting terminals 111 complete the electrical connection with the circuit board 3. When in the second operation state, the circuit board 3 leaves the insulating base 12 and the conductive terminals 11, and at this time, the conductive terminals 11 release the electrical connection with the circuit board 3 and are in the second shape shown in fig. 4 under the influence of the elastic restoring force, so that the connecting ends 111 are displaced to make a part of the connecting ends 111 located in the inserting operation structure to wait for the electrical connection with the circuit board 3 at the next stage.

Alternatively, as shown in fig. 4 and 9, in the present invention, the insulating base 12 has a deformation space 123 and an observation window 124, the deformation space 123 can provide a space for the conductive terminal 11 to deform therein, so that the shape of the conductive terminal 11 can be switched between the first shape and the second shape. As shown in fig. 4 and 9, the observation window 124 is connected to the deformation space 123 for visually observing whether the conductive terminal 11 is in the first shape or the second shape as expected, and even as shown in fig. 2 and 7, the observation window 124 can also provide a visual observation for visually observing whether the bonding end 111 is in the first shape or the second shape as expected or for releasing the electrical bonding of the circuit board 3, so that the user can effectively grasp the electrical bonding state of the wire-to-board connector 1 to the circuit board 3 without using other observation instruments.

As shown in fig. 8 and 9, the wire-to-board connector 1 of the present invention may further include a clamping terminal 13 for clamping the circuit board 2. Specifically, when the wire-to-board connector 1 is in the first operating state, the clamping terminals 13 provide clamping of the circuit board 3 as shown in fig. 10, and provide maintenance of the relative positional relationship between the wire-to-board connector 1 and the circuit board 3, that is, the relative movement between the wire-to-board connector 1 and the circuit board 3 is restricted; when the wire-to-board connector 1 is in the second operating state, the clamping terminals 13 release the clamping of the circuit board 3 as shown in fig. 5, and the relative positional relationship between the wire-to-board connector 1 and the circuit board 3 is released, i.e., the wire-to-board connector 1 and the circuit board 3 can move relatively.

As shown in fig. 5 and 10, the clamping terminal 13 has an upper clamping arm 131 and a lower clamping arm 132 for clamping the circuit board 3. In the present invention, the wire-to-board connector 1 has a plurality of clamping terminals 13 respectively disposed on the left and right sides of the insulating base 12, and clamps the circuit board 3 on the left and right sides of the insulating base 12, so as to maintain the electrical connection between the wire-to-board connector 1 and the circuit board 3.

It should be noted that, in the present invention, the clamping terminal 13 is not an essential component and can be omitted.

In summary, the wire-to-board connector of the present invention can directly electrically contact the circuit board, so that the circuit board can be applied to the light, thin, short and small electronic device with limited internal space without additional board end connectors. In addition, in the wire-to-board connector, the insulating base is designed with a welding operation structure, and the wire is electrically connected with the conductive terminal by a welding mode, so that the size of the wire-to-board connector can be reduced, the conductive terminal does not need to be electrically connected with the wire in the manufacturing process of the wire-to-board connector, and the manufacturing procedure of the wire-to-board connector can be simplified.
