Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of connectors, and more particularly relates to a ZIF connector and an electronic device. BACKGROUND

[0002] With the rapid development of the consumer electronics field, the printed circuit board assembly (PCBA), i.e., the mainboard, is also updated. As a medium for the PCBA and external components, the requirement for the versatility of the function of the connector is also higher and higher.

[0003] The ZIF connector is one of the most widely used connectors at present. However, the current ZIF connector simply guides the position of the cable terminal to the PCBA. It cannot realize the conduction of the positive terminal sequence and the reverse terminal sequence at the same time. For example, the ZIF connector in the prior art belongs to a straight-through type connection, so the terminal sequence at the PCBA end must be consistent with the terminal sequence at the wiring end. When the cable is inserted in the positive direction, the gold fingers of the cable are inserted downward. Taking a four-terminal as an example, the first terminal of the cable is at the right side of the insertion end, so the first terminal of the PCBA is also at the right side of the insertion end of the ZIF connector. Due to the straight-through nature of the current ZIF connector, the first terminal of the ZIF connector is also at the right end. When the cable is inserted in the reverse direction, the gold fingers are inserted on the upper surface, the first terminal of the ZIF connector is at the left end of the connector, and the fourth terminal of the ZIF connector is at the right end. At this time, the fourth terminal of the ZIF connector is connected to the first terminal of the PCBA, and the VCC terminal and the GND terminal are connected, which will cause the circuit to break and the board to be damaged.

Please refer to Figures 1-5 The first aspect of the embodiment of the present application provides a ZIF connector, which comprises an insulating seat 1, a locking cover 2, a first spring group 3 and a second spring group 4 which are arranged on the insulating seat 1 and are oppositely spaced apart;

[0048] The insulating seat 1 has a plug-in slot 11 and a containing slot 12 of the locking cover 2, the locking cover 2 is rotationally connected to the insulating seat 1, the first spring group 3 comprises a plurality of first springs 31, the second spring group 4 comprises a plurality of second springs 41, the first springs 31 and the second springs 41 are movably connected to the insulating seat 1, and the locking cover 2 is used to lock or unlock the first ends of the first springs 31 and the first ends of the second springs 41 from a connecting piece inserted into the plug-in slot 11 under the action of an external force;

[0049] A plurality of adapter circuits 5 are arranged in the locking cover 2, when the connecting piece is locked, the second ends of the first springs 31 are electrically connected to the adapter circuits 5, and the adapter circuits 5 are used to output the signals of the first ends of the first springs 31 to the second ends of the second springs 41 in a preset sequence.

[0050] The ZIF connector of the embodiment can be a wire-to-board connector or a wire-to-wire connector (such as FFC to FPC, cable to FPC, and FPC to FPC), and the size and application occasion of the ZIF connector are not particularly limited in the embodiment.

[0051] The specific material and size of the insulating base 1 are not particularly limited in the embodiment. The insulating base 1 has a plug-in slot 11 and a containing slot 12 of the locking cover 2. The first spring piece group 3 and the second spring piece group 4 are oppositely and spacedly arranged on the insulating base 1. The first spring piece group 3 and the second spring piece group 4 are used for clamping a connecting piece inserted into the plug-in slot 11. For example, the connecting piece is a cable. The first spring piece group 3 includes a plurality of first spring pieces 31. The second spring piece group 4 includes a plurality of second spring pieces 41. The specific number of the first spring pieces 31 and the second spring pieces 41 is not particularly limited in the embodiment.

[0052] The locking cover 2 is used for locking or unlocking the connecting piece inserted into the plug-in slot 11 under the action of an external force, and the first end of the first spring piece 31 and the first end of the second spring piece 41 are driven. For example, the locking cover 2 has a rotating shaft 21 at both ends. When the locking cover 2 is perpendicular to the insulating base 1, the connecting piece is unlocked in the plug-in slot 11. When the locking cover 2 is in a horizontal state, the locking cover 2 locks the connecting piece.

[0053] A plurality of adapter lines 5 are arranged in the locking cover 2. When the connecting piece is locked, the second end of the first spring piece 31 is electrically connected to the adapter line 5 in the locking cover 2. The adapter line 5 is used for outputting a signal on the first spring piece 31 to the second end of the second spring piece 41 in a preset sequence. The second end of the second spring piece 41 is used for electrical connection with a mainboard. The number of the first spring pieces 31, the number of the second spring pieces 41, and the number of the adapter lines 5 match the number of functional terminals of the connecting piece. The connecting piece is generally a cable. The number of the first spring pieces 31, the number of the second spring pieces 41, and the number of the adapter lines 5 are not particularly limited in the embodiment. For example, the adapter line 5 can be fixed in the locking cover 2 by injection molding. The second end of the second spring piece 41 is used for electrical connection with a PCBA board or an FPC.

[0054] The working principle of the ZIF connector is as follows: please refer to Figure 5From the left end, the cable is inserted into the insertion slot 11 of the ZIF connector, the lower surface of the cable is a gold finger (conductive), and the upper surface is a plastic plate. When the cable gold finger is inserted downward, the cable is locked by rotating the locking cover 2 with external force. The second end of the second spring plate 41 in this embodiment is welded to the PCBA board or FPC. In this state, the signal on the cable gold finger is conducted to the PCBA board or FPC through the first end of the second spring plate 41 and the second end of the second spring plate 41. When the cable gold finger is on the upper surface and the lower surface is a plastic reinforcing plate. After locking the cable by rotating the locking cover 2 with external force, the signal in the cable is introduced into the adapter circuit 5 in the locking cover 2 through the first spring plate 31, and then transmitted to the second end of the second spring plate 41 through the adapter circuit 5 in the locking cover 2. The ZIF connector of this embodiment can output the signals on the first spring plate 31 and the second spring plate 41 to the PCBA board or FPC, and the insertion of the connector is not limited by the function terminal defined by the line end of the PCBA board.

[0055] The ZIF connector provided in this embodiment includes an insulating seat, a locking cover, a first spring plate group and a second spring plate group arranged on the insulating seat and spaced apart from each other. The insulating seat has an insertion slot and a receiving slot of the locking cover. The locking cover is rotationally connected to the insulating seat. The first spring plate group includes a plurality of first spring plates. The second spring plate group includes a plurality of second spring plates. The first spring plates and the second spring plates are movably connected to the insulating seat. The locking cover is used to lock or unlock the connector inserted into the insertion slot through the first end of the first spring plate and the first end of the second spring plate under the action of external force. A plurality of adapter circuits are arranged in the locking cover. When the connector is locked, the second end of the first spring plate is electrically connected to the adapter circuit. The adapter circuit is used to output the signal of the first end of the first spring plate to the second end of the second spring plate in a preset sequence. The signal contacted by the first end of the first spring plate and the first end of the second spring plate of the ZIF connector is not output from the same output terminal. The signal input from the first spring plate is output to the second end of the second spring plate in a preset sequence through the adapter circuit. The first end of the first spring plate and the first end of the second spring plate of the ZIF connector are separate lines, which are no longer limited by the function terminal defined by the line end of the mainboard.

[0056] Please refer to Figures 5-7 In a specific embodiment, the first end of the adapter circuit 5 is used to be electrically connected to the second end of the first spring plate 31, and the second end of the adapter circuit 5 is used to be electrically connected to the second end of the second spring plate 41. The first end of the adapter circuit 5 is fixed on the locking cover 2 in a first sequence arrangement manner, and the second end of the adapter circuit 5 is fixed on the locking cover 2 in a second sequence arrangement manner. The number of the adapter circuit 5 in this embodiment is related to the use scene of the ZIF connector, and the specific number of the adapter circuit 5 is not particularly limited in this embodiment.

[0057] Optionally, the first sequence is the reverse of the second sequence, or the first sequence is an incorrect sequence of the second sequence.

[0058] The following explanation illustrates the signal transmission of the ZIF connector adapter line when the first sequence is the reverse of the second sequence:

[0059] Specifically, please refer to 6 and Figure 7 This embodiment uses a four-terminal cable as an example. One side of the cable is the gold finger side, and the other side is the plastic side. Insert the cable from the left end of the ZIF connector, with the gold finger side facing down. Please refer to [link to relevant documentation]. Figure 7 The gold finger terminals are arranged from bottom to top as pin 1, pin 2, pin 3, and pin 4. The gold fingers directly contact the first end of the second spring 41. The signal of gold finger pin 1 is output to the external port of the motherboard through the second end of the second spring 41 (i.e., point A in the figure); the signal of gold finger pin 2 is output to the external port of the motherboard through the second end of the second spring 41 (i.e., point B in the figure); the signal of gold finger pin 3 is output to the external port of the motherboard through the second end of the second spring 41 (i.e., point C in the figure); and the signal of gold finger pin 4 is output to the external port of the motherboard through the second end of the second spring 41 (i.e., point D in the figure).

[0060] When the cable is inserted with the gold fingers facing upwards, the gold finger terminal sequence from bottom to top is pin 4, pin 3, pin 2, pin 1 (…). Figure 7 (Not shown in the diagram) This is the reverse sequence of the above terminal arrangement. The gold fingers directly contact the first end of the first spring 31. After the locking cover 2 is closed and locked, the gold finger pin 1 signal is output from the second end of the first spring 31, transmitted through line a in the piano cover 2 to the second end of the second spring 41 (i.e., point A in the diagram), and output to the external port of the motherboard. Similarly, the gold finger pin 2 signal is output from the second end of the first spring 31, transmitted through line b in the locking cover 2 to the second end of the second spring 41 (i.e., point B in the diagram), and output to the external port of the motherboard; the gold finger pin 3 signal is output from the second end of the first spring 31, transmitted through line c in the locking cover 2 to the second end of the second spring 41 (i.e., point C in the diagram), and output to the external port of the motherboard. The gold finger pin 4 signal is output from the second end of the first spring 31, transmitted through line d in the locking cover 2 to the second end of the second spring 41 (i.e., point D in the diagram), and output to the external port of the motherboard.

[0061] The ZIF connector in this embodiment allows the same cable (FFC / FPC) to be inserted into the ZIF connector in either direction (with the gold fingers facing up or down), and the corresponding signals transmitted to the motherboard are the same, so the motherboard circuitry can be standardized.

[0062] The principle that the first sequence is the reverse sequence of the second sequence is similar to the principle that the first sequence is the wrong sequence of the second sequence, and the embodiment will not be described again.

[0063] Please refer to Figure 5 and Figure 8 Further, the first end of the adapter wire 5 is provided with a first copper 51, and the first copper 51 is fixed on the locking cover 2.

[0064] The second end of the adapter wire 5 is provided with a second copper 52, and the second copper 52 is fixed on the locking cover 2. The second copper 52 is used to abut against the second end of the second elastic sheet 41 when the first end of the second elastic sheet 41 locks the connecting piece. The first end of the adapter wire 5 of the embodiment is electrically connected with the second end of the first elastic sheet 31 through the first copper 51, the contact area between the second end of the first elastic sheet 31 and the first end of the adapter wire 5 is large, the second end of the adapter wire 5 is electrically connected with the second end of the second elastic sheet 41 through the second copper 52, the contact area between the second end of the second elastic sheet 41 and the second end of the adapter wire 5 is large, and the transmission stability of the circuit signal can be ensured.

The locking cover 2 is provided with a second inclined surface 222 for fitting the second end of the second elastic sheet 41 when the connecting piece is locked, and the second copper 52 is fixed on the second inclined surface 222.

[0066] The first inclined surface 221 of the embodiment is used to abut against the first elastic sheet 31 when the connecting piece is locked. The first inclined surface 221 ensures that the locking cover and the second end of the first elastic sheet 31 are in full contact, the adapter wire 5 is stably electrically connected with the second end of the first elastic sheet 31, the first end of the first elastic sheet 31 is stably connected with the locking cover 2, the second inclined surface 222 is used to abut against the second elastic sheet 41 when the connecting piece is locked, the adapter wire 5 is stably electrically connected with the second end of the second elastic sheet 41, and the first end of the second elastic sheet 41 is stably connected with the locking cover 2.

[0068] Referring to Figure 5 In an embodiment, the first elastic sheet 31 is provided with an arc-shaped protrusion 311, the first opening is provided with an arc-shaped groove matched with the arc-shaped protrusion 311, and the first end of the first elastic sheet 31 abuts against the wall of the insertion slot 11 when the connecting piece is not inserted into the insertion slot 11. In the embodiment, the arc-shaped protrusion 311 is arranged on the first elastic sheet 31, the arc-shaped groove matched with the arc-shaped protrusion 311 is arranged in the first opening, the second end of the first elastic sheet 31 is pushed by the push of the locking cover 2, the arc-shaped protrusion 311 rotates in the arc-shaped groove to make the first end of the first elastic sheet 31 press downward, and the connecting piece is locked. The first elastic sheet 31 of the embodiment is simple in matched structure with the insulating base 1 and simple in manufacturing mode.
