Description

Technical Field

[0001] This utility model relates to the field of sheet metal technology, and in particular to a piercing double-row connector and its male head, vertical female head and horizontal female head. Background Technology

[0002] Connectors, specifically male and female connectors, are mating components used for circuit connections in electronic devices. Male connectors typically have pins or protruding contacts, while female connectors are designed with sockets or recessed interfaces, ensuring stable mating and signal or power transmission. Male connectors are mostly used in cable ends, while female connectors are commonly found in device ports, secured by mechanical clips, threads, or other methods to prevent accidental detachment. They are primarily made of metals such as copper alloys and plastics, balancing conductivity and insulation. Widely used in consumer electronics, industrial equipment, and communications, types include USB, HDMI, and D-Sub, and their standardized design ensures compatibility and reliability.

[0003] Existing connectors are mainly composed of plastic and copper alloy, relying on mechanical contact of metal contacts to achieve power transmission and signal transmission.

[0004] However, during assembly, it is necessary to distinguish the positive and negative sides. Incorrect orientation can easily lead to reversed positive and negative power supply and signal transmission after the male and female connectors make contact. Metal wear and corrosion can increase contact resistance, slow down signal transmission, and cause oxidation of the plating after wear. Under high temperature and high humidity, the plating may become poorly contacted, resulting in unstable power supply, obstructed signal integrity, and reduced mechanical wear strength at the board end and wire end, leading to a reduced plug-in life. Utility Model Content

[0005] In view of the above problems, embodiments of the present invention are proposed to provide a piercing double-row connector and its male, upright female, and horizontal female connectors that overcome or at least partially solve the above problems:

[0006] The male connector for piercing double-row connectors is used to connect with the vertical and horizontal female connectors for piercing double-row connectors. It includes the male connector housing, wire, and piercing terminals.

[0007] The piercing terminal is disposed in the middle of the male connector housing, and both ends of the piercing terminal are in contact with the outside. The wire is engaged with the male connector housing through the piercing terminal.

[0008] The male connector housing includes a first metal contact channel, a second metal contact channel, and an extended housing for fixing the wire. The bottom of the extended housing is connected to the first metal contact channel and the second metal contact channel. The first metal contact channel and the second metal contact channel are arranged opposite to each other. Both the first metal contact channel and the second metal contact channel are in communication with the outside.

[0011] The wire fixing cavity is connected to the first metal contact channel.

[0012] Preferably, the piercing terminal is a gold-plated piercing terminal; the piercing terminal has a slot in the middle for fixing the wire;

[0021] To achieve this, the application also includes a piercing double-row connector, comprising: a piercing double-row connector male head as described, and a piercing double-row connector horizontal female head as described.

[0022] The male connector of the piercing double-row connector is connected to the female connector of the piercing double-row connector.

[0023] This application specifically includes the following advantages:

[0024] In the embodiments of this application, compared with the prior art which requires distinguishing between positive and negative, this application provides a method with two double-row metal conductive contact points, so that the wire end can be contacted after insertion regardless of direction, thus preventing the positive and negative power conduction and signal transmission from being reversed when the male and female connectors come into contact. The male connector shell is thickened and slotted to guide and avoid contact with the other side of the metal, thereby enhancing the insertion and extraction force of the male and female connectors.

The extended and thickened male connector improves compatibility with the female connector, resulting in stronger insertion and extraction forces. Inserting the male wire into the female connector does not require distinguishing between the front and back, making the assembly process smoother for customers. Attached Figure Description

[0042] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0043] The inventors discovered through analysis of existing technologies that connectors are mainly composed of plastic and copper alloys, relying on mechanical contact of metal contacts to achieve power transmission and signal transmission. The copper alloy plating is mainly tin-plated. Metal wear and corrosion lead to increased contact resistance, slower signal transmission, oxidation after plating wear, poor contact, unstable power supply, and obstructed signal integrity under high temperature and high humidity. The mechanical wear strength of the board end and wire end decreases, resulting in a reduced mating life.

[0044] Reference Figures 1-7 The diagram shows a structural schematic of the male connector 1 of the present invention, which specifically includes the following structure: a male connector housing 11, a wire 12, and a piercing terminal 13; the piercing terminal 13 is disposed in the middle of the male connector housing 11, and both ends of the piercing terminal 13 are in contact with the outside; the wire 12 is engaged with the male connector housing 11 through the piercing terminal 13; the male connector housing 11 includes a first metal contact channel 112, a second metal contact channel 113, and an extended housing 111 for fixing the wire 12; the bottom of the extended housing 111 is connected to the first metal contact channel 112 and the second metal contact channel 113; the first metal contact channel 112 and the second metal contact channel 113 are arranged opposite to each other; both the first metal contact channel 112 and the second metal contact channel 113 are in communication with the outside. The number of wires 12 in the male connector is unlimited; it can be 2, 3, 4, etc., and the number of other components increases accordingly. For example, two wires 12 can be equipped with two first metal contact channels 112, two piercing terminals 13, and two second metal contact channels 113, etc. The female connector changes accordingly; if two wires 12 are provided, then two sets of horizontal terminals 33 or two sets of vertical terminals 23 are provided.

[0045] The male connector 1 of the piercing double-row connector in this exemplary embodiment will now be further described.

[0046] In one embodiment of this application, the male connector housing 11 includes a first metal contact channel 112, a second metal contact channel 113, and an extended housing 111 for fixing the wire 12. The bottom of the extended housing 111 is connected to the first metal contact channel 112 and the second metal contact channel 113. The first metal contact channel 112 and the second metal contact channel 113 are disposed opposite to each other. Both the first metal contact channel 112 and the second metal contact channel 113 are in communication with the outside.

[0047] As an example, the male housing 11 is a plastic housing, and the extended housing 111 is used to fix the wire 12. It is provided with wire 12 fixing cavities adapted to the wire 12, and the number of wires 12 is the same as the number of wire 12 fixing cavities.

[0048] In one embodiment of this application, the extended housing 111 has a wire 12 fixing cavity on one side that is connected to the outside, and the other side of the extended housing 111 is sealed; the extended housing 111 and the male housing 11 are integrally formed; the wire 12 fixing cavity is connected to the first metal contact channel 112.

[0049] As an example, the extended housing 111 is sealed on the opposite side of the fixing cavity of the wire 12, so that one side of the wire 12 is in contact with the outside, while the other side is wrapped by the extended housing 111. The fixing cavity of the wire 12 is connected to the first metal contact channel 112 below, and the two are integrally formed. The second metal contact channel 113 is provided on the opposite side of the first metal contact channel 112, so that the wire 12 has dual-channel contact. The two metal conductive contact points are arranged in two rows, and the wire end can be contacted after insertion in any direction, which prevents the positive and negative current and signal transmission from being reversed when the male and female connectors come into contact. The male connector housing 11 is thickened and slotted to guide and avoid the other side of the metal contact, which enhances the insertion and extraction force of the male and female connectors. The male connector housing is lengthened to better clamp the wire 12 and enhance the tensile force between the wire 12 and the male connector housing. The female connector uses the same assembled fixing piece on both the vertical and horizontal sides, which can achieve a shared effect.

[0050] In one specific embodiment of this application, the male connector housing 11 adopts a dual-metal contact channel structure to improve the reliability and versatility of the connector. Specifically, the male connector housing 11 includes a first metal contact channel 112 and a second metal contact channel 113, which are arranged opposite to each other and connected to the outside to ensure bidirectional conduction of signals or current. The extended housing 111 is integrally formed with the male connector housing 11, and its bottom is connected to the two metal contact channels to form a stable physical support. The core function of the extended housing 111 is to fix the wires 12. It has wire fixing cavities inside that match the number of wires 12, ensuring that each wire 12 can be accurately positioned and fixed. This integrated design not only simplifies the assembly process but also enhances the mechanical strength of the overall structure. The first metal contact channel 112 is provided on one side of the male connector housing 11, and the second metal contact channel 113 is provided on the other side of the male connector housing 11.

[0051] In one specific embodiment, the wire 12 fixing cavity design of the extended housing 111 balances openness and sealing. One side is open to the outside, facilitating the insertion and fixing of the wire 12; the other side is completely sealed, effectively protecting the wire 12 from external environmental corrosion. The wire 12 fixing cavity is directly connected to the first metal contact channel 112, ensuring the continuity of electrical connection. This semi-open structure allows one side of the wire 12 to contact the outside while the other side is completely enclosed by the extended housing 111, facilitating operation and providing necessary protection. Furthermore, the symmetrical layout of the bimetallic contact channels allows the wire 12 to achieve conduction regardless of its orientation, fundamentally avoiding errors in power supply or signal transmission caused by reverse insertion, significantly improving ease of use and safety.

[0052] In one specific embodiment, the thickened slotted design of the wire 12 fixing cavity in the male connector housing 11 further optimizes the mechanical performance of the connector. The slotted design, acting as a guide structure, effectively avoids metal contact points on the other side, ensuring precise mating of the male and female connectors during insertion, while also enhancing insertion and extraction force to prevent accidental dislodgement. The extended portion of the elongated housing 111 significantly increases the clamping force of the wire 12, making the connection between the wire 12 and the male connector housing 11 more robust. The female connector uses an assembly-type fixing piece compatible with both vertical and horizontal mounting, achieving component standardization and reducing production costs. The overall design, through innovations such as dual-channel contact, thickened guide slots, and modular fixing pieces, achieves a balance between electrical performance, mechanical strength, and assembly efficiency, making it suitable for connection scenarios with high reliability requirements.

[0053] In this embodiment, the piercing terminal 13 is disposed in the middle of the male connector housing 11, and both ends of the piercing terminal 13 are in contact with the outside. The wire 12 is engaged with the male connector housing 11 through the piercing terminal 13.

[0054] In this embodiment of the application, the piercing terminal 13 has a first set of contact points 131 and a second set of contact points 132 on one side, and the first set of contact points 131 and the second set of contact points 132 are arranged in parallel; the piercing terminal 13 has a third set of contact points 131 on the other side; the first set of contact points 131, the second set of contact points 132 and the third set of contact points 131 are all in communication with the outside world.

[0055] In this embodiment, the piercing terminal 13 is a gold-plated piercing terminal 13; the piercing terminal 13 has a slot in the middle for fixing the wire 12; the slot has a first set of contact points 131 and a second set of contact points 132 on one side, and a third set of contact points 131 on the other side.

[0056] As an example, each group of contact points includes two contact points, one on the left and one on the right. Specifically, the first group of contact points 131 includes a first left contact point and a first right contact point arranged side-by-side; the second group of contact points 132 includes a second left contact point and a second right contact point arranged side-by-side; and the third group of contact points 131 includes a third left contact point and a third right contact point arranged side-by-side. The first left and first right contact points are arranged around the wire 12, thus forming a central slot. The second left contact point is located below the first left contact point, and the second right contact point is located below the first right contact point. The third left and third right contact points are located on the other side.

[0057] In one specific embodiment of this application, the piercing terminal 13 optimizes the connection between the wire 12 and the male connector housing 11, improving electrical conductivity and mechanical stability. The piercing terminal 13 is fixed in the middle within the male connector housing 11, while its two ends are in contact with the outside, ensuring effective signal or current transmission. The wire 12 is securely engaged with the male connector housing 11 through the slots of the piercing terminal 13, forming a reliable physical connection. The piercing terminal 13 uses a gold-plating process, which not only enhances conductivity but also improves corrosion resistance, making it suitable for high-frequency signal or high-current transmission scenarios. The slot design allows the wire 12 to be precisely fixed, avoiding poor contact caused by vibration or pulling.

[0058] In one specific embodiment of this application, the contact points of the piercing terminal 13 adopt a multi-set symmetrical layout to ensure the stability and versatility of the connection. One side of the terminal has a first and second set of contact points 132 arranged in parallel, and the other side has a third set of contact points 131. All three sets of contact points are connected to the outside, forming a bidirectional conduction path. Each set of contact points includes two symmetrically distributed contact points on the left and right sides. For example, the first set of contact points 131 consists of a first left contact point and a first right contact point, which are arranged around the slot to form a ring structure to securely clamp the wire 12. The second set of contact points 132 is located below the first set and adopts the same left-right symmetrical layout, further enhancing contact reliability. This design allows the wire 12 to be clamped at multiple points during insertion, ensuring a low-impedance connection.

[0059] In one specific embodiment of this application, the third set of contact points 131 is located on the other side of the piercing terminal 13, and also adopts a symmetrical design, including a third left contact point and a third right contact point. This double-sided contact structure ensures stable conduction regardless of which direction the terminal is inserted, effectively avoiding circuit failures caused by reverse insertion. The synergistic effect of the three sets of contact points not only increases the contact area but also enhances insertion and removal durability. In addition, the integrated design of the slot and contact points simplifies the assembly process and reduces production costs. Overall, the piercing terminal 13, through gold plating, multi-point contact, and symmetrical layout, optimizes electrical performance, mechanical strength, and ease of operation, making it suitable for connector applications with high reliability requirements.

[0060] The piercing double-row connector vertical female head 2 in this exemplary embodiment will now be further described. (Refer to...) Figures 8-10 The diagram shows a structural schematic of the piercing double-row connector vertical female head 2 of this utility model.

[0061] In this embodiment, the vertical mounting head includes a vertical mounting base plate 24, a vertical mounting housing 21, a vertical mounting fixing piece 22, and a vertical mounting terminal 23; the vertical mounting housing 21 is embedded with the vertical mounting fixing piece 22 on both sides, one end of the vertical mounting terminal 23 is disposed in the vertical mounting housing 21, and the other end of the vertical mounting terminal 23 is connected to the outside; the vertical mounting terminal 23 is perpendicular to the vertical mounting base plate 24.

[0062] In this embodiment of the application, the upright terminal 23 includes a first upright terminal 231 and a second upright terminal 232; the first upright terminal 231 and the second upright terminal 232 have the same shape and are arranged opposite to each other.

[0063] As an example, the mounting housing 21 is also made of plastic. Both sides of the mounting housing 21 are connected to the mounting base plate 24 via mounting fixing pieces 22. The mounting fixing pieces 22 include a first mounting piece and a second mounting piece, which are symmetrically arranged. The first mounting terminal 231 is connected to the first set of contact points 131 and the second set of contact points 132, and the second mounting terminal 232 is connected to the third set of contact points 131.

[0064] In one specific embodiment, the vertical female connector adopts a modular layout to improve assembly efficiency and connection stability. The vertical female connector mainly consists of a vertical base plate 24, a vertical housing 21, vertical fixing pieces 22, and vertical terminals 23. These components work together to form a compact and reliable connection unit. The vertical housing 21 is made of plastic, with symmetrically arranged vertical fixing pieces 22 embedded on both sides for secure connection to the vertical base plate 24. The vertical terminals 23 are vertically mounted on the vertical base plate 24, with one end fixed inside the vertical housing 21 and the other end connected to the outside, ensuring effective signal or current transmission. This vertical layout not only saves space but also facilitates mating with other connectors.

[0065] In one specific embodiment, the upright terminal 23 adopts a symmetrical design, including a first upright terminal 231 and a second upright terminal 232 of the same shape and arranged opposite to each other. The first upright terminal 231 is connected to the first and second sets of contact points 132 of the piercing terminal 13, while the second upright terminal 232 is connected to the third set of contact points 131, forming a bidirectional conduction path. The upright fixing piece 22 is further subdivided into a first upright piece and a second upright piece, which are symmetrically distributed on both sides of the upright housing 21 and fixed to the upright base plate 24 by mechanical snap-fit ​​or welding. This symmetrical structure not only enhances the overall mechanical strength but also simplifies the assembly process and ensures precise docking between the terminal and the contact point.

[0066] In one specific embodiment, the design of the vertical female connector fully considers versatility and durability. The integrated design of the vertical housing 21 and the vertical fixing piece 22 reduces the number of parts while improving vibration and tensile strength. The gold plating of the vertical terminal 23 further optimizes conductivity and corrosion resistance, making it suitable for high-frequency or high-current applications. Furthermore, the vertical female connector can be blind-molded with the male housing 11 via dual-channel contact points, avoiding connection failures due to incorrect orientation. Overall, the vertical female connector achieves a balance between compact structure, efficient assembly, and stable performance through its modular symmetrical design, vertical terminal layout, and high-reliability materials, making it suitable for various high-precision connection requirements.

[0067] The piercing double-row connector horizontal female head 3 in this exemplary embodiment will now be further described. (Refer to...) Figures 11-13The diagram shows a schematic of the horizontal female head 3 of the piercing double-row connector of this utility model.

[0068] In this embodiment, the device includes a horizontal base plate 34, a horizontal housing 31, a horizontal fixing piece 32, and a horizontal terminal 33. The horizontal fixing pieces 32 are embedded in both sides of the horizontal housing 31. One end of the horizontal terminal 33 is disposed inside the horizontal housing 31, and the other end of the horizontal terminal 33 is connected to the outside. The horizontal terminal 33 is arranged parallel to the horizontal base plate 34.

[0069] In this embodiment, the horizontal contact terminal 33 includes a first horizontal contact terminal 331 and a second horizontal contact terminal 332; the first horizontal contact terminal 331 and the second horizontal contact terminal 332 are arranged in parallel.

[0070] As an example, the mounting housing 31 is also made of plastic. Both sides of the mounting housing 31 are connected to the mounting base plate 34 via mounting fixing pieces 32. The mounting fixing pieces 32 include a first mounting piece and a second mounting piece, which are symmetrically arranged. The first mounting terminal 331 is connected to the first set of contact points 131 and the second set of contact points 132, and the second mounting terminal 332 is connected to the third set of contact points 131.

[0071] As an example, the first horizontal terminal 331 is "L" shaped, and the second horizontal terminal 332 is a vertical line.

[0072] In one specific embodiment, the horizontal female connector adopts a horizontal layout design, forming a complementary installation scheme with the vertical female connector. The horizontal female connector 33 and the horizontal female connector base plate 34 are arranged parallel to each other, a structure particularly suitable for use in horizontal installation scenarios with limited space. The first horizontal female connector 331 adopts an innovative "L"-shaped structure, achieving a longer contact path in a limited space and enhancing signal transmission stability; while the second horizontal female connector 332 is designed as a simple straight line, and the two are arranged in parallel to form an efficient current path. This differentiated design ensures contact reliability while optimizing space utilization.

[0073] In one specific embodiment, the symmetrical arrangement of the horizontal mounting plates 32 continues the modular concept of the connectors in this application series. The first and second horizontal mounting plates are arranged in a mirror image on both sides of the horizontal mounting housing 31. This design not only facilitates automated assembly but also effectively disperses mechanical stress during insertion and removal. The plastic horizontal mounting housing 31 is integrally molded with the mounting plates through injection molding, ensuring both structural strength and good insulation performance. The parallel layout of the horizontal mounting terminals 33 forms a three-dimensional cross-contact network with the dual-channel contact points of the male connector housing 11. When mating with the male connector, the "L"-shaped first horizontal mounting terminal 331 can simultaneously contact the first and second sets of contact points 132, while the straight second horizontal mounting terminal 332 is specifically designed to contact the third set of contact points 131. This three-dimensional contact method significantly improves the stability and fault tolerance of the connection.

[0074] In one specific embodiment, the difference between the horizontal female connector and the vertical female connector is that the horizontal female connector is arranged parallel to the base plate, while the vertical female connector is arranged perpendicular to the base plate, and the male connector is inserted in different directions.

[0075] A piercing double-row connector includes: a piercing double-row connector male head 1 as described above, and a piercing double-row connector female head 2 as described above; the piercing double-row connector male head 1 is connected to the piercing double-row connector female head 2.

[0076] A piercing double-row connector includes: a piercing double-row connector male head 1 as described above, and a piercing double-row connector horizontal female head 3 as described above; the piercing double-row connector male head 1 is connected to the piercing double-row connector horizontal female head 3.

[0077] In one specific embodiment, the male connector 1 of the piercing double-row connector represents the wire end, which consists of an extended plastic shell and a piercing terminal. The wire is made of UL10064#32AWG wire. The wire end is assembled from the piercing terminal to the fixed position of the plastic shell, and then the wire is pierced and pressed into the middle of the terminal to form a piercing wire harness.

[0078] The female connector represents the patch pin header. The female connector consists of the pin header body, positioning plate, vertical patch terminal, and horizontal patch terminal. The vertical patch is a 180-degree interlocking connector, assembled with vertical patch terminal 23, vertical patch fixing plate 22, and vertical patch housing 21. The horizontal patch is a 90-degree interlocking connector, assembled with horizontal patch terminal 33, horizontal patch fixing plate 32, and horizontal patch housing 31.

[0079] In one specific embodiment, the double-row metal plate of the female connector strengthens the fixation between the PCB board and the female connector. The male connector is lengthened and thickened for better compatibility with the female connector, resulting in stronger insertion and extraction forces. The male connector wire ends do not require differentiation between the front and back sides when inserted into the female connector, making the assembly process smoother for customers. The accompanying 0.8mm pitch double-row vertical and horizontal surface mount connectors, along with their male housings and terminals, are directly applicable to 3C digital products, lighting fixtures, electronic cigarettes, small-space circuits, and information transmission functions.
