Description

Technical Field

[0001] This utility model relates to the field of diode technology, and specifically to a diode assembly. Background Technology

[0002] As a fundamental semiconductor device, the diode has unidirectional conductivity and is widely used in many fields such as electronic circuits, electrical equipment, and industrial control. It undertakes key functions such as rectification, detection, voltage regulation, and switching, and is one of the important components to ensure the normal operation of various electronic and electrical systems.

[0003] Currently, most diodes on the market exist as standalone units, typically consisting only of the diode chip itself and terminals extending from both ends. In practical applications, these diodes are directly exposed in circuits or devices, achieving electrical connection with external circuits through soldering or bonding via the terminals. However, this traditional standalone usage mode has significant shortcomings in protection performance, making it difficult to meet the needs of complex application scenarios.

[0004] Specifically, exposed diodes lack effective physical protection structures. On the one hand, during transportation, installation, and subsequent use, they are highly susceptible to damage from external mechanical impacts, squeezing, or friction, which can lead to chip damage, terminal deformation, or even breakage, causing diode failure and affecting the stability of the entire system. On the other hand, dust, moisture, oil, and other impurities in the external environment can easily adhere to the diode surface or penetrate its interior, causing problems such as terminal oxidation and corrosion, and decreased chip insulation performance. This not only reduces the diode's conductivity and lifespan but can also lead to safety hazards such as short circuits and leakage in severe cases.

[0005] The aforementioned shortcomings of traditional exposed diodes are particularly pronounced in applications with high requirements for component protection, such as industrial control, automotive electronics, and outdoor electrical equipment. Although some applications may provide simple protection for diodes by adding protective shells or sealants, these post-installation protective measures often suffer from cumbersome installation, poor compatibility, and difficulty in achieving accurate and reliable protection. Furthermore, they increase the overall circuit assembly cost and size, hindering the miniaturization and integration of equipment.

[0006] Furthermore, the traditional method of directly soldering individual diodes to external circuits via terminals is not only difficult to operate and requires a high level of technical skill from installers, but also necessitates disassembling the solder joints when replacing or maintaining the diode, which is inconvenient and can easily damage surrounding circuits. At the same time, the stability of this connection method is greatly affected by the soldering process; poor soldering quality can easily lead to poor contact, affecting the diode's operating performance.

[0007] In summary, existing diodes used alone and exposed suffer from insufficient protection, poor connection stability, inconvenient installation and maintenance, and low adaptability, making it difficult to meet the demands of modern electronic and electrical equipment for high protection, high reliability, and easy installation of components. Therefore, developing a technical solution that can effectively improve the protection level of diodes and provide convenient and stable connections has become an urgent technical problem to be solved in this field.

[0009] The technical solution adopted in this utility model is: a diode assembly, comprising, Two prongs are arranged side by side, one end of each prong is bent to form a connecting part, and a connecting groove is provided on the connecting part; A diode, wherein the terminals at both ends of the diode are inserted into a connecting groove and welded to the connecting part; The outer casing has a connecting mechanism on one side of its outer wall for connecting with external components; A cap, which seals and fits onto the inner cavity opening of the outer casing; One end of the connector of the pin passes through the cover and extends into the outer casing, while the other end extends out of the cover.

[0016] The beneficial effects of this utility model are: 1. Enhanced Protection Level: The diode is encapsulated within the housing cavity through a sealed fit between the outer casing and the cap, forming all-around physical protection. This effectively isolates the diode chip and terminals from damage caused by external mechanical collisions, compression, and friction. It also prevents the intrusion of impurities such as dust, moisture, and oil, avoiding problems such as oxidation and corrosion of the terminals and degradation of chip insulation performance. This reduces safety hazards such as short circuits and leakage, extends the diode's lifespan, and makes it suitable for high-standard protection scenarios such as industrial control, automotive electronics, and outdoor equipment.

[0017] 2. Convenient and stable connection: The pin structure adopts a bent connection part with a connection groove.

[0019] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0022] Figure 2 This is an exploded view of the present invention.

[0023] Figure 3 This is a schematic diagram of the outer shell. Detailed Implementation

[0024] 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.

[0025] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0026] This utility model provides a diode assembly.

[0027] In this embodiment, refer to Figure 1-3 The diode assembly includes, Two pins 1 are arranged side by side, one end of each pin is bent to form a connecting part 2, and a connecting groove 3 is provided on the connecting part; Diode 4, the terminals at both ends of the diode 4 are inserted into the connecting groove and welded to the connecting part; The outer casing 5 has a connecting mechanism on one side of its outer wall for connecting with external components; The cover 16 is sealed and fits onto the inner cavity opening 6 of the outer shell; One end of the connector of the pin 1 passes through the cover and extends into the outer casing, while the other end extends out of the cover.

[0028] The above technical solution adopts an integrated structural design of "pin-diode-casing-cap". The pin is bent to form a connecting part with a connection groove, providing a positioning and soldering base for the diode terminal. The cap seals the inner cavity of the casing, while the pin protrudes for connection, encapsulating the diode within the closed cavity. One end of the pin is exposed for mating with a dedicated connector. This effectively improves the protection level; the diode is enclosed and protected, isolating it from mechanical damage and impurity intrusion, significantly enhancing the protection level. The pin is firmly soldered to the diode with precise positioning, and the exposed end allows for convenient mating with the dedicated connector, replacing traditional direct soldering, reducing installation difficulty and improving connection stability. The integrated structure reduces scattered components, adapting to the integration requirements of equipment.

[0029] Specifically, the inner cavity of the outer shell is filled with epoxy resin.

[0030] In this embodiment, epoxy resin is filled into the inner cavity of the outer shell. The insulating, sealing and shaping properties of the epoxy resin after curing are used to completely wrap the diode and the pin connection part in the inner cavity, forming a multi-dimensional filling and sealing structure.

[0031] Specifically, the connecting mechanism includes two guide protrusions 7 disposed on the outer wall of the housing and a hook step 8 disposed between the two guide protrusions 7. The two guide protrusions are arranged in parallel, and the end of the hook step is provided with a first guide slope 9.

[0032] In this embodiment, the connecting mechanism consists of a parallel guide convex plate and a hook step. The guide convex plate provides guidance and positioning for the engagement with external components. The hook step guides the external components to quickly engage through the first guide slope at the end, and the step structure is used to achieve axial limiting and fixing.

[0033] Specifically, the surface of the outer shell is provided with reinforcing ribs 10 at intervals.

[0034] In this embodiment, reinforcing ribs are spaced apart on the surface of the outer shell. The rib structure increases the moment of inertia of the outer shell wall, improves the overall structural strength of the outer shell, and disperses external forces.

[0035] Specifically, at least two sealing rings 11 are provided on the inner cavity opening of the outer shell.

[0036] In this embodiment, at least two sealing rings are provided at the inner cavity opening of the outer shell. The sealing rings are made of elastic materials (such as rubber, silicone, etc.). When the cover is sealed and closed at the inner cavity opening of the outer shell, the contact surface between the cover and the outer shell opening will exert a squeezing effect on the sealing rings, causing the sealing rings to undergo elastic deformation and fill the gap between the cover and the outer shell opening, forming multiple independent sealing contact interfaces, constructing multiple sealing defenses, and extending the protective validity period of the product.

[0037] Specifically, the cover has raised steps 12 on both sides, the inner wall of the outer shell has an insert groove 13 that fits into the raised steps, and a second guide slope 14 is provided on one side of the raised steps.

[0038] In this embodiment, a concave-convex mating structure of "protruding steps - fitting slots" is used to connect and position the cap and the outer shell. Protruding steps are provided on both sides of the cap, and corresponding fitting slots that match the size and shape of the protruding steps are machined on the inner wall of the outer shell cavity. When the cap is closed, the second guide slope on one side of the protruding step forms a guiding fit with the entrance of the fitting slot. The guiding effect of the slope reduces the resistance of the protruding step embedding into the fitting slot, allowing the protruding step to be accurately embedded in the fitting slot, forming a mechanical interlocking positioning, and achieving a seal with the sealing ring.

[0039] Specifically, the inner wall of the outer shell is provided with a separation step 15 for separating the two pins.

[0040] In this embodiment, a separation step is provided on the inner wall of the outer shell corresponding to the arrangement position of the two pins. The height of the separation step is higher than the thickness of the pins, and the width matches the distance between the two pins, so that the separation step is perpendicularly separated between the two pins, forming a physical barrier structure, which restricts the displacement of the two pins in the lateral direction (perpendicular to the length of the pins) and prevents the pins from getting close to or contacting each other.

[0041] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
