[0002] In connectors, the conventional setup uses wires to achieve reliable transmission of electrical signals and mechanical connection. In the prior art, connector wires are often arranged in a single row. The single row arrangement reduces the lateral width, making it suitable for narrow or high-density installation environments. The single row of pins also facilitates PCB routing, reduces crossings and interlayer transitions, and lowers design complexity. However, the connection density per unit space is low, and the wires are longer, resulting in longer signal paths, which is not conducive to signal transmission. Utility Model Content

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] Please see Figure 1-4 The preferred embodiment of this utility model provides a dual-wire stacked connector, including a housing 1, a PCB board 2, a power cord 3 and several wires 4. The PCB board 2 is disposed inside the housing 1, and the housing 1 can serve as insulation. The wires 4 are used to connect to the PCB board 2 and are used to transmit electrical signals or power. One end of the power cord 3 is fixed to the housing 1 and connected to the PCB board 2, and the power cord 3 is used to transmit electrical energy.

[0025] Specifically, the two ends of the wire 4 are a first connecting end 41 and a second connecting end 42, respectively. The first connecting end 41 is connected to the PCB board 2, and the second connecting end 42 extends out of the housing 1. Several wires 4 are arranged in two equal rows, with the two rows of wires 4 facing each other and the two rows of second connecting ends 42 stacked. The first connecting end 41 is fixed to the PCB board 2. The housing 1 protects the PCB board 2 and further prevents the first connecting end 41 from detaching from the PCB board 2. The double-row arrangement of the wires 4 increases the connection density to the PCB board 2 per unit space, reducing the area occupied by the PCB board 2 and facilitating the installation of other components on the PCB board 2. Furthermore, since the two rows of wires 4 are facing each other and the two rows of second connecting ends 42 are stacked without gaps, it is beneficial to reduce the thickness of the housing 1, thereby reducing the overall size of the connector and facilitating the layout of other components.

[0026] Furthermore, the PCB board 2 is provided with two rows of first connecting holes 21 and two rows of second connecting holes 22. The two rows of first connecting holes 21 are arranged opposite each other and spaced apart. The two rows of first connecting ends 41 are respectively connected to the two rows of first connecting holes 21. The arrangement of the first connecting holes 21 is used to define the position of the first connecting ends 41, so as to fix the first connecting ends 41 on the PCB board 2. The two rows of second connecting holes 22 are staggered. The power line 3 is connected to the two rows of second connecting holes 22 through several wires (not shown in the figure). This connection method can reduce contact resistance and facilitate the transmission of large current.

[0027] More specifically, both rows of first connecting ends 41 are provided with exposed conductors 411, and the two rows of conductors 411 are respectively provided with upward bending and downward bending parts 412. The two rows of bending parts 412 pass through the two rows of first connecting holes 21 in two opposite directions. The two rows of bending parts 412 do not interfere with each other, which is conducive to neat wiring and allows wiring to be done on both sides of the PCB board 2, reducing the overall volume occupied.

[0028] In this embodiment, the bent portion 412 is welded to the first connecting hole 21. The metal-to-metal connection formed by welding has extremely low resistance, which is beneficial for high current transmission. Furthermore, the rigid connection formed after welding has excellent vibration and impact resistance and high reliability.

[0029] The outer casing 1 is provided with a first connecting part 11 and a second connecting part 12, which are respectively connected to opposite sides of the outer casing 1. The second connecting part 12 is provided with a mounting hole 121, and one end of the power cord 3 is located in the mounting hole 121 to limit the wiring of the power cord 3. The first connecting part 11 is provided with two rows of through holes 111, and two rows of second connecting ends 42 extend out of the two rows of through holes 111 respectively. The two rows of through holes 111 are arranged vertically opposite each other, and each through hole 111 in the upper row is connected to each through hole 111 in the lower row in a figure-eight pattern. The through holes 111 can limit the wiring of the second connecting ends 42, prevent the second connecting ends 42 from shifting, and ensure the stacking of the two rows of second connecting ends 42.

[0030] The first connecting portion 11 has several positioning holes 112 on both opposite sides. Adjacent positioning holes 112 are staggered. The positioning holes 112 communicate with several through holes 111. The outer shell 1 is made of plastic. The protrusions on the mold for manufacturing the outer shell 1 can pass through the positioning holes 112 and abut against the second connecting end 42 to prevent the second connecting end 42 from shifting during the manufacturing process of the outer shell 1. In this embodiment, the positioning holes 112 are oblong holes. Oblong holes have high tolerance for positional accuracy, are easy to process, and help reduce the scrap rate.

[0031] In this embodiment, the outer shell 1 is integrally formed with the PCB board 2 and the wire 4 by overmolding. After the wire 4 and the power cord 3 are fixed on the PCB board 2, overmolding is performed around the PCB board 2. The resulting outer shell 1 covers the PCB board 2, which can provide high protection for the PCB board 2 and improve the compactness of the entire connector.

[0032] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
