Description

Technical Field

[0001] This utility model relates to the field of power electronics technology, and in particular to a housing structure with a two-in-one terminal. Background Technology

[0002] In the field of electronic circuits, surface mount inductors and transformers, as core components for power conversion, signal filtering, and energy storage, are widely used in various products such as communication equipment, consumer electronics, and automotive electronics. To ensure the structural stability, electrical reliability, and ease of assembly of these components, they are usually encased in a dedicated housing. The terminals integrated on the housing are the key components for connecting the component to external circuits. One end of the terminal needs to form a solid mechanical and electrical connection with the PCB board using surface mount technology (SMT), while the other end is used to wind the coil leads inside the component. The tight contact between the leads and the terminal establishes a current path, ensuring the effective transmission of electrical energy or signals. Currently, most surface mount inductors and transformers on the market use an integrated structure of "single winding end - single power connection end" for their casing terminals, meaning that each terminal has only one end for winding the coil lead. In actual production and application scenarios, when the component design requires connecting two different coil leads at the same circuit node (e.g., to achieve winding taps, parallel connection of multiple windings, or connection of specific phases), the operator must wind both leads together on the winding end of the same terminal. However, this method has significant drawbacks: firstly, when two leads are wound together, the contact area between the leads is limited, and it is difficult to ensure a tight fit between the two leads and the terminal surface during the winding process, which can easily lead to loosening due to uneven winding tension; secondly, during subsequent transportation, soldering, or long-term use of the component, environmental factors such as vibration and temperature changes can easily cause the originally loosely fitted leads to fall off (i.e., "wire detachment"). Once a circuit goes offline, it will not only cause the electrical performance of components to fail and trigger the entire circuit to malfunction, but it will also increase the product rework rate and production costs, seriously affecting production efficiency and product quality stability.

[0003] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a housing structure with a two-in-one terminal, comprising a housing, wherein the housing has a coil groove, and terminal assemblies are provided on both sides of the groove opening edge of the coil groove, wherein the terminal assembly includes a winding end for winding coil lead wire and a mounting end for mounting on a PCB board; The winding end is provided with at least two, and the two winding ends are connected to the mounting end.

[0006] As a further embodiment of this utility model: the two winding ends and the mounting ends are an integral structure.

[0007] As a further embodiment of this utility model: the groove edge of the coil groove is formed with a mounting surface, the winding end protrudes from the mounting surface, and the mounting end protrudes from the side of the housing and is bent to be in the same direction as the mounting surface.

[0008] As a further embodiment of this utility model: the winding end includes two winding portions and a horizontal connecting portion, the two ends of the horizontal connecting portion are respectively connected to the two winding portions, and the mounting end is connected to the side of the horizontal connecting portion away from the direction of the two winding portions. The mounting end includes a connecting section, a vertical section, and a mounting section. The connecting section is connected to the horizontal joint, and the vertical section is connected to the connecting section and, after being bent, faces the same direction as the winding section. The connecting section extends from the side of the shell and connects to the vertical section.

[0009] As a further embodiment of this utility model: the mounting section is connected to the vertical section and is bent to form a plane that can be bonded to the PCB board.

[0010] As a further embodiment of this utility model: winding gaps are formed on both sides of the winding portion.

[0011] As a further embodiment of this utility model: multiple wire routing grooves corresponding to each winding part are provided on both sides of the coil groove.

[0012] Compared with existing technologies, the beneficial effects of this technical solution are as follows: By setting two winding ends, two different coil pins can be wound onto the two winding ends respectively. Since both winding ends are connected to the mounting end to form a two-in-one structure, both pins can be electrically connected to the same contact point on the PCB board through the mounting end. This completely solves the problem of loosening and wire breakage caused by two pins being wrapped together on one winding end, ensures the winding tension between the two pins and the winding end, improves the stability of the pin connection, avoids circuit failures caused by wire breakage, and makes the winding of pins quick and convenient, improving product quality stability and production efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 A housing structure with a two-in-one terminal includes a housing 1, the housing 1 having a coil groove 2, and terminal assemblies 3 being provided on both sides of the groove edge of the coil groove 2. The terminal assembly 3 includes a winding end 4 for winding coil lead wires and a mounting end 5 for mounting on a PCB board. The winding end 4 is provided in at least two parts, and the two winding ends 4 are connected to the mounting end 5.

[0018] Specifically, by setting two winding ends 4, two different coil pins can be wound onto the two winding ends 4 respectively. Since both winding ends 4 are connected to the mounting end 5 to form a two-in-one structure, both pins can be electrically connected to the same contact point on the PCB board through the mounting end 5. This completely solves the problem of loosening and wire breakage caused by two pins being wrapped together on one winding end, ensures the winding tension between the two pins and the winding end 4, improves the stability of the pin connection, avoids circuit failures caused by wire breakage, and makes the winding of pins quick and convenient, improving product quality stability and production efficiency.

[0019] Preferably, the two winding ends 4 and the mounting ends 5 are an integral structure, which ensures the structural strength and electrical conductivity between the two winding ends 4 and the mounting ends 5, without the need for additional assembly and fixing, thus improving production efficiency.

[0020] Based on the above, it is further proposed that the groove edge of the coil groove 2 is formed with a mounting surface 6, the winding end 4 protrudes from the mounting surface 6, and the mounting end 5 protrudes from the side of the housing 1 and is bent to be in the same direction as the mounting surface 6.

[0021] Specifically, mounting surface 6 is the side of the inductor component that is opposite to the PCB board when it is mounted. The winding end 4 protrudes from mounting surface 6, which provides sufficient operating space for winding the lead wire and provides winding speed. The orientation of the mounting end 5 after bending is the same as that of the winding end 4, and the contact end of the mounting end 5 with the PCB board should protrude from the winding end 4. That is, after the mounting end 5 contacts and is soldered to the PCB board, the winding end 4 maintains a distance from the PCB board to avoid faults such as short circuits.

[0022] Based on the above embodiments, it is further proposed that the winding end 4 includes two winding portions 41 and a transverse connection portion 42. The two ends of the transverse connection portion 42 are respectively connected to the two winding portions 41, and the mounting end 5 is connected to the side of the transverse connection portion 42 away from the direction of the two winding portions 41. The mounting end 5 includes a connecting section 51, a vertical section 52 and a mounting section 53. The connecting section 51 is connected to the horizontal joint 42, and the vertical section 52 is connected to the connecting section 51 and is bent to be aligned with the orientation of the winding section 41. The connecting section 51 extends from the side end of the housing 1 and connects to the vertical section 52.

[0023] Specifically, the horizontal connecting part 42 is used to realize the synchronous fixation and electrical conduction of the two winding parts 41. On the other side of the horizontal connecting part 42, it is connected to the connecting section 51 of the mounting end 5. After the connecting section 51 protrudes from the side end of the housing 1, it is connected to the vertical section 52. Then, the vertical section 52 extends to the mounting surface 6 after being bent and connects to the mounting section 53. The mounting section 53 is then soldered to the soldering point on the PCB board. In this design, the wire-wrapped end 4 and the mounting end 5 protected in the terminal assembly 3 are both embedded in the housing 1 using a pre-embedded manufacturing process, forming an integrated design that ensures a robust overall structure between the terminal assembly 3 and the housing 1. During component transportation, installation, or long-term use, this effectively resists external forces such as vibration and impact, preventing lead wire detachment or mounting misalignment due to terminal loosening. Figure 1 and Figure 2 As shown, the transverse joint 42 of the winding end 4 is embedded inside the housing 1, and the connecting section 51 of the mounting end 5 extends out from the side end of the housing 1 after being connected to the transverse joint 42.

[0024] Preferably, the mounting section 53 is connected to the vertical section 52 and is bent to form a plane that can be bonded to the PCB board.

[0025] Specifically, the planar design of the mounting section 53 can increase the contact area with the solder joints on the PCB board, improve the adhesion after soldering, and ensure the stability of the mounting.

[0026] Based on the above embodiments, it is further proposed that the winding portion 41 has winding gaps 43 formed on both sides.

[0027] Specifically, the design of the winding notch 43 limits the lead wire while it is being wound, preventing the lead wire from slipping on the winding part 41.

[0028] Based on the above embodiments, it is further proposed that multiple wire routing grooves 21 corresponding to each winding part 41 are opened on both sides of the coil groove 2.

[0029] Specifically, the wiring groove 21 provides a corresponding channel for the lead wires of the coil, which is conducive to the sorting and guidance of the lead wires and avoids the lead wires from crossing, tangling and messy placement.

[0030] Preferably, a single terminal 7 is provided on both sides of the groove edge of the coil groove 2. The single terminal 7 has only one winding end and one mounting end.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
