[0032] To more clearly illustrate the present invention, the present invention will be further described below in conjunction with embodiments and drawings. Similar components in the drawings are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the protection scope of the present invention.

[0033] In the prior art, there is a problem that when the mixed-mounted bent plug connector is welded with the through-hole pins of the printed circuit board, it is limited by the wire-out ability of the printed circuit board. When the existing mixed-mounted bent plug connector is welded with through-hole pins, since it can only be installed on one printed circuit board, limited by the wiring ability of the printed circuit board, it is not easy to lead out the wiring of the high-density mixed-mounted bent plug connector in the printed circuit board.

[0034] In view of this, an embodiment of the present invention provides a bent plug connector. A bent plug connector is characterized in that the bent plug connector includes a plugging part, a flange, a tail end part, a plurality of bent pin groups and a plurality of first printed circuit boards; the flange is used to mount the bent plug connector on a first device, the plugging part is arranged on the front end face of the flange to be exposed outside the first device, and the plugging part is used to connect a second device; the tail end part is arranged on the rear end face of the flange to be arranged inside the first device; the plurality of bent pin groups are arranged on the rear end face of the tail end part, one end of the plurality of bent pin groups is connected to the plugging part, and the other ends of the plurality of bent pin groups facing different directions are respectively soldered to a plurality of first printed circuit boards, and the plurality of first printed circuit boards are respectively connected to a plurality of circuit boards of the first device.

[0035] In a specific example, the way of leading out the pins of the connector is increased from a single direction to multiple different directions, so that the bent plug connection originally installed on one circuit board can be installed on multiple independent printed circuit boards, thereby solving the problem that within the same through-hole pin soldering width range, restricted by the connection and lead-out of a single printed circuit board, the installation space cannot be effectively utilized. The bent plug connector in this example is simultaneously through-hole pin soldered with multiple printed circuit boards, which can increase the connector density of the mixed-mounted bent plug connector, enabling the high-density bent plug connector to be more flexible and applicable to a wider range of fields and environments.

[0036] The pin leading-out directions of the bent plug connector adopted in this embodiment are not limited to the upper and lower two directions, and can be extended to multiple required directions to realize the installation of the bent plug connector with multiple groups of printed boards, greatly improving the electrical density (connector density) of the bent plug connector.

[0037] In a possible implementation manner, the plurality of bent pin groups facing different directions include bent pin groups facing at least two directions.

[0038] In a specific example, as Figure 1 and Figure 2 shown, the bent plug connector, namely the high-density mixed-mounted bent plug connector, is composed of a flange, a plugging part, a mounting hole (for mounting the bent plug connector), group A pins, group B pins, the rear end face of the flange, etc.

[0039] The method of leading out pins from the upper and lower two directions for the bent plug connector adopted in this embodiment solves the mutual restriction of pins when leading out from a single direction and can greatly improve the connector density of the bent plug connector.

[0040] In a specific example, as Figure 1 and Figure 2As shown, the pins of Group A and Group B of the high-density mixed-mounted bent pin connectors are led out from the rear end face of the flange of the bent pin connector. Different from the existing mixed-mounted bent pin connectors, the number of pin orientations is increased from one to two or more groups, namely, Group A pins facing upward and Group B pins facing downward.

[0041] Furthermore, multiple groups mean two or more groups. For example, Figure 1 and Figure 2 show the lead-out methods of one group facing upward (Group A pins) and another group facing downward (Group B pins).

[0042] Furthermore, other forms include one group facing upward and another group facing right; or one group facing downward, one group facing left, and one group facing right; or one group facing upward, one group facing left, one group facing right, and one group facing downward, etc. There are various combinations. This solution is introduced only by taking the example of one group facing upward (Group A pins) and one group facing downward (Group B pins).

[0043] In this embodiment, the method of leading out the grouped pins of the bent pin connector from different directions can better solve the problem of the connection and wire-out between the bent pin connector and the printed circuit board in the case of mixed use of large and small pins and mixed use of different signals, and further improve the compatibility of the bent pin connector.

[0044] In a possible implementation, the bent pin groups facing the same direction include one group of bent pin, or the bent pin groups facing the same direction include multiple different groups of bent pins.

[0045] In a specific example, as Figure 3 shown, the bent pins of Group A pins facing upward are the same, and the bent pins of Group B pins facing downward are the same.

[0046] In another specific example, as Figure 9 shown, the bent pins of Group A1 pins, Group A2 pins, Group A3 pins, and Group A4 pins facing upward are different.

[0047] In yet another specific example, as Figure 10 shown, the bent pins of Group B1 pins, Group B2 pins, Group B3 pins, and Group B4 pins facing downward are different.

[0048] In a possible implementation, the tail end portion is provided with a plurality of through holes, and one end of the plurality of bent pin groups is connected to the plugging portion through the plurality of through holes.

[0049] In a specific example, as Figure 1 and Figure 2 shown, the bent pin connector further includes a tail end portion connected to the rear end face of the flange.

[0050] In this embodiment, since the high-density mixed-mounted bent pin connector is no longer installed on a single circuit board, it can prevent the electrical signals of the internal contacts from being difficult to lead out due to the concentration of pins, solving the problem that existing connectors have to increase the width of the connector or the number of connectors. This embodiment can increase the electrical density of the connector under the same installation width.

[0051] In this embodiment, since the high-density bent pin printed circuit board connector differentiates the lead-out directions of the bent pin connectors, it can further better suit the installation in the case of mixed use of large and small pins or mixed installation of signals such as current and communication. And because it can be differentiated and led out according to the magnitude of the current or different communication types, it is more conducive to the miniaturization and light weight of electrical devices, making the applied space vehicle devices, shipborne and airborne equipment smaller and more integrated, and thus improving the loading capacity of our country's electronic equipment.

[0052] In this embodiment, the lead-out of different groups of pins in different directions increases the wiring from originally only on one group of printed circuit boards to two groups of printed circuit boards, increasing the electrical density of the bent pin connector.

[0053] In this embodiment, the connection of multiple groups of pins to different printed circuit boards greatly reduces the difficulty of electrical design, improves the development progress and reliability of the product. Further, the external installation connector surface of the device can be reduced, which is beneficial to the miniaturization development of electrical devices.

[0054] In a possible implementation manner, each of the first printed circuit boards includes a plurality of pad holes corresponding one-to-one to each bent pin in the corresponding bent pin group, and the plurality of pad holes are used to weld each of the first printed circuit boards to the corresponding bent pin group.

[0055] In a specific example, as Figure 3 shown, Printed Circuit Board A, that is, the printed circuit board, and Printed Circuit Board B are composed of mounting holes (for mounting the printed circuit board), pad holes, etc. Printed Circuit Board A and Printed Circuit Board B are only for illustration and are not necessarily the same.

[0056] In a specific example, as Figure 4 shown, it includes a high-density mixed-mounted bent pin connector, Printed Circuit Board A and Printed Circuit Board B. The pins of Group A of the high-density mixed-mounted bent pin connector are inserted into the corresponding pad holes of Printed Circuit Board A and welded and fixed; the pins of Group B of the high-density mixed-mounted bent pin connector are inserted into the corresponding pad holes of Printed Circuit Board B and welded and fixed.

[0057] Furthermore, as Figure 4 shown, since the high-density mixed-mounted bent pin connector is installed on both Printed Circuit Board A and Printed Circuit Board B at the same time, within the same installation range, the connection and wiring area between the high-density mixed-mounted bent pin connector and the printed circuit board increases exponentially, greatly improving the electrical density of the mixed-mounted bent pin connector, making its layout and structure more flexible and capable of adapting to more application environments.

[0058] The method of leading out pins in multiple directions adopted in this embodiment increases the number of groups of the installation of the bent pin connector and the printed circuit board from one group to two groups or more, greatly improving the ability to lead out the signals of the contact parts in the installation area after the connection between the bent pin connector and the printed circuit board in the printed circuit.

[0059] In a possible implementation manner, the bent pin connector further includes a flexible circuit board and a second printed circuit board, and the first printed circuit board is electrically connected to the second printed circuit board through the flexible circuit board.

[0060] In a specific example, as Figure 5 shown, the connection between the high-density bent pin connector and the printed circuit board includes a high-density bent pin connector, a group A rigid-flexible board, a group B rigid-flexible board, etc.

[0061] Furthermore, both the group A rigid-flexible board and the group B rigid-flexible board have a printed circuit board 1 (i.e., the first printed circuit board), a printed circuit board 2 (i.e., the second printed circuit board), and a flexible printed circuit board. The printed circuit board 1 and the printed circuit board 2 are connected through the flexible printed circuit board, and the printed circuit board 1 is provided with solder pad holes corresponding to the pins of group A or group B of the high-density bent pin connector and meeting the specifications and quantities. The printed circuit board 1, the printed circuit board 2, and the flexible printed circuit board only represent the same composition in the group A rigid-flexible board and the group B rigid-flexible board, and do not represent the same part or the same portion. More specifically, the printed circuit board 1 in the group A rigid-flexible board is not necessarily the same as the printed circuit board 1 in the group B rigid-flexible board.

[0062] Furthermore, the pins of group A of the high-density bent pin connector are inserted into the corresponding solder pad holes of the printed circuit board 1 of the group A rigid-flexible board for soldering, and the pins of group B of the high-density bent pin connector are inserted into the corresponding solder pad holes of the printed circuit board 1 of the group B rigid-flexible board for soldering.

[0063] In a possible implementation manner, the bent pin connector further includes a plurality of locking brackets connected to the rear end face of the tail end portion, and the plurality of locking brackets are used to fix the plurality of first printed circuit boards.

[0064] In a specific example, as Figure 6 shown, the bent pin connector further includes a plurality of locking brackets connected to the rear end face of the tail end portion, and the locking brackets are used to fix the first printed circuit board.

[0065] In a possible implementation manner, the locking brackets are arranged on one side of the first printed circuit board far from the end of the bent pin pins.

[0066] In a specific example, as Figure 6 shown, the locking brackets are arranged on one side of the first printed circuit board (printed circuit board 1) far from the end of the bent pin pins. The locking brackets are arranged on one side of the first printed circuit board (printed circuit board 2) far from the end of the bent pin pins.

[0067] In a possible implementation, the second printed circuit board is electrically connected to the circuit board through a stacking connector.

[0068] In a specific example, such as Figure 7 and Figure 8 shown, the connector X2 is a connector assembly welded to the A group of rigid-flexible boards and the B group of rigid-flexible boards, and is welded with a stacking connector for docking. The connector X1 is a common bent plug connector and a rigid-flexible board welding assembly, and is welded with a stacking connector for docking.

[0069] In a specific example, such as Figure 7 and Figure 8 shown, the connector X1 assembly and the connector X2 assembly are installed on the structural housing using corresponding locking parts and through the mounting holes of the flange. Various structural parts and other circuit boards and other functional devices are installed inside the structural housing to complete the assembly of the electric control device.

[0070] Another embodiment of the present invention provides an electric control device including a plurality of bent plug connectors as described in an embodiment of the present invention.

[0071] In a specific example, the electric control device further includes a structural housing, a rear cover, a support member 1, and a support member 2.

[0072] Since the high-density mixed-mounted bent plug connector in this embodiment is no longer installed on a single circuit board, it can prevent the electrical signals of the internal contacts from being difficult to lead out due to the concentration of pins, and solve the problem that the existing connectors have to increase the connector width or the number of connectors. This embodiment can increase the electrical density of the connector under the same installation width.

[0073] Since the high-density bent plug printed circuit board connector in this embodiment makes a distinction in the lead-out direction of the bent plug connector, it can further better adapt to the installation in the case of mixed use of large and small pins, or the mixed installation of signals such as current and communication. And because it can be distinguished and led out according to the magnitude of the current or different communication, it is beneficial to the mutual isolation and anti-interference of signals, and is more beneficial to the miniaturization and light weight of the electrical device, making the applied space vehicle device, shipborne, and airborne equipment miniaturized and integrated, thereby improving the loading capacity of our country's electronic equipment.

[0074] The lead-out of different directions of multiple groups of pins in this embodiment increases the wiring from originally only on one group of printed circuit boards to two groups of printed circuit boards, increasing the electrical density of the bent plug connector.

[0075] The connection of multiple groups of pins to different printed circuit boards in this embodiment greatly reduces the difficulty of electrical design, improves the development progress and reliability of the product. Further, the external installation connector surface of the device can be reduced, which is beneficial to the miniaturization development of the electrical device.

[0076] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to enumerate all implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
