Description

Technical Field

[0001] This disclosure generally relates to an electrical connection with thermal and vibration protection, and more specifically, to a thermally conductive shielding device including a cable restraint mechanism for mechanically connecting to an electronic product housing, such that the cable and connector are thermally protected and restrained from excessive vibration. Background Technology

[0002] In high-voltage and high-temperature applications, plastic connectors may fail or experience reduced performance due to vibration and high ambient temperatures. In vehicle engine applications, the high temperatures generated by engine exhaust can cause thermal damage to electronic components, printed circuit boards, and electrical system cables and harnesses. When connectors overheat, they may melt, deform, or even catch fire. This can damage motors, connectors, and other devices in the circuit. For example, high heat may cause electrical connectors to melt close to metal surfaces, reducing the connector's current rating and / or causing premature connector failure.

[0003] Typical automotive electrical connectors rely on spring contacts in the plug and socket to form an easily detachable and reusable connection. These spring contacts form a connection between the two sides of the connector and rely on spring force to maintain the connection. In high-current applications, the contact area is very limited, so heat can accumulate at these contact points. Furthermore, the cost-effective plastic connector housing is susceptible to damage during impacts, leading to a high risk of exposure to high-voltage and current electrical contacts.

[0004] An additional problem with spring-loaded connectors in automotive applications is that the conductive coating within the connector can be lost due to wear caused by vibration. Typically, spring connectors and their crimped terminals are plated with highly conductive metals, such as tin, gold, or silver, to prevent corrosion and oxidation, which increases connection resistance. These plating metals are often also soft metals that are easily worn. In high-vibration automotive applications, even minor movements of the components or cables to which the connector is attached can cause small relative movements between the spring contacts and their mating terminals, resulting in wear on the terminal plating, a sharp increase in contact resistance, and consequently, heat generation. Therefore, it is desirable to provide enhanced thermal and vibration protection for these cost-effective plastic connectors, while also preventing connector damage in the event of a vehicle collision or other vehicle damage incidents. Other desirable features and characteristics of this disclosure will become apparent from the following detailed description of embodiments, discussed in conjunction with the accompanying drawings and background art, and from the appended claims.

[0030] The following specific embodiments are merely exemplary in nature and are not intended to limit this disclosure or its application and use. Furthermore, this disclosure is not intended to be bound by any theory presented in the foregoing background or the following specific embodiments.

[0031] More broadly, the exemplary embodiments disclosed herein include an improved thermal, shock, and vibration shielding for high-voltage connectors. This improved thermal, shock, and vibration shielding may include a tight-fitting metal tube covering a plastic high-voltage cable connector. The shielding may mate with a liquid-cooled electronic housing to conduct heat from the shielding to the electronic housing, thereby reducing the temperature of the shielding to below the ambient air temperature surrounding the connector. Furthermore, the cable from the connector may be clamped by the connector integrated with the shielding to prevent excessive cable movement and to prevent vibration transmission to the connector, which could cause wear on the plating at the connector contacts.

[0032] Thermal protection is an important safety and reliability feature that helps prevent fires and equipment damage. Vibration control and thermal protection are important design principles when integrating an internal combustion engine into an electrical system. Proper thermal protection and vibration control improve vehicle safety, extend the lifespan of electrical connectors by preventing overheating and failure, reduce maintenance costs by preventing expensive repairs or replacements of electrical connectors, and contribute to improved electrical system reliability by preventing failures caused by overheating.

[0033] Now turn to Figure 1 An exemplary environment 100 is shown, according to various embodiments, for an improved high-voltage connector thermal, impact, and vibration cable shield 115. This exemplary environment 100 shows an electronic housing 105, shield 115, shielding gasket 110, cable clamp 120, cable 125, and electrical connector 130.

[0034] The electronic housing 105 may be a metallic, liquid-cooled housing for housing and protecting circuitry, printed circuit boards, and other sensitive electronic components. The electronic housing 105 may be made of aluminum, copper, or other thermally conductive materials. The electronic housing 105 may include a top portion and a bottom portion, which may be mechanically connected by fasteners 140 such as screws or bolts. Prior to mechanically securing the top and bottom portions, an electronic package, such as a printed circuit board (PCB) or the like, may be inserted into and secured within the electronic housing 105. An electrical connector 130 may be aligned with an opening in the electronic housing 105 to allow power supply and data communication to the printed circuit board when the electronic housing 105 is installed. In some exemplary embodiments, the electronic housing 105 may be secured to a heat-controlled automotive component, such as an engine block or battery housing, such that heat energy can be transferred from the electronic housing 105 to the heat-controlled automotive component.

[0035] The electronic enclosure 105 protects printed circuit boards (PCBs) and electronic components from a variety of environmental factors, including moisture, dust, dirt, extreme temperatures, electromagnetic interference, and vibration. The metal enclosure effectively isolates sensitive electronic components from moisture that can cause corrosion and electrical short circuits. Furthermore, it prevents the accumulation of dust and dirt on the electronic system. Without protection, dust and dirt can accumulate on electronic components, causing them to overheat and potentially fail, thus shortening component lifespan. The metal enclosure also shields sensitive electronic circuitry from extreme temperatures (high and low) and can be designed with vibration damping to reduce the risk of damage. In addition, the metal circuit enclosure protects electronic components and circuits from electromagnetic interference generated by engine ignition systems and other high-current systems, preventing damage to electronic signals transmitted and received through electronic components and reducing the likelihood of damage to the electronic system caused by induced currents and the like.

[0036] The exemplary environment shows an electrical connector 130 not connected to the corresponding cable, and another electrical connector connected to the cable and fitted with a cable shield 115 according to an exemplary embodiment. In some exemplary embodiments, both electrical connectors may be configured to allow the cable shield to be installed. The cable shield 115 may include a snap-fit ​​metal tube pressed over the plastic cable connector to act as shock protection in the event of a vehicle collision. The cable shield may be mechanically fastened to the housing 105 by one or more bolts passing through flanges in the cable shield and screwed into corresponding threaded holes in the housing 105. In some exemplary embodiments, configuring the cable shield 115 to be mechanically coupled to the electronic housing 105 allows heat energy to be coupled from the cable shield 115 to the electronic housing 105. This allows the cable shield 115 to remain significantly cooler than the ambient air temperature of the engine compartment surrounding the electrical connector and the corresponding cable, enabling the connector to conduct higher currents without derating due to high ambient temperatures. Bolted U-clamps at the ends hold the cable extending from the connector toward the battery. This prevents excessive cable movement and vibration from being transmitted to the connector and also avoids wear on the plating.

[0037] In some exemplary embodiments, a gasket 110 may be installed between the cable shield 115 and the electronic housing 105. The gasket 110 may be made of a flexible conductive or non-conductive material and serves to maintain an environmental protection barrier between the interior of the electronic housing 105 and the surrounding environment. The gasket 110 may be formed of a thermally conductive material to allow thermal energy to be connected from the cable shield 115 to the electronic housing 105. Similarly, the gasket 110 may be formed of a conductive material, such as braided copper, to conduct electricity between the cable shield 115 and the electronic housing 105. The conductive gasket material allows electrical energy from the ground shield on the cable 125 to be electrically connected to the cable shield 115, thereby conducting any electrical energy received in the environment to the ground shield of the cable 125, connected to the electronic housing 105 via the cable shield 115 and the conductive gasket 110. This arrangement allows unwanted electromagnetic interference to be grounded to the engine block via the electronic housing 105, rather than to the ground plane of the PCB within the electronic housing 105.

[0038] In some exemplary embodiments, the material of the gasket 110 may be selected to prevent any potential electrochemical effects and associated corrosion between the different metals of the electronic housing 105 and the cable shield 115. Electrochemical corrosion is a type of corrosion that occurs when two different metals are in electrical contact with each other in the presence of an electrolyte. The electrolyte can be a liquid, such as water, or a gas, such as air. When the two metals are in contact, an electric current flows between them. This current can cause one metal to corrode more than the other. The gasket 110 may be designed to limit electrochemical corrosion by providing a barrier between the two metals. The gasket prevents the flow of electrons between the metals, which prevents corrosion. When selecting the material for the gasket 110 to prevent electrochemical corrosion, several factors should be considered, including the type of metal that will be in contact with the gasket 110, the environment in which the gasket will be used, and the pressure and temperature to which the gasket 110 will be exposed. The type of gasket selected should be compatible with the type of metal it will be in contact with. For example, a gasket made of a conductive material should not be used between two different metals that are in contact with each other in the presence of an electrolyte.

[0039] Cable shield 115 may be equipped with cable clamps 120 for supporting cable 125 to reduce vibration and torque experienced by the connector due to cable movement. In some exemplary embodiments, cable clamp 120 may include one or more mechanical fasteners 121 for mechanically securing cable clamp 120 to another rigid body within the engine compartment environment, such as an engine block, intake manifold, or the like. Ideally, cable clamp 120 should be secured to the same component to which the electronic housing is attached to reduce deflection and torsional stress between cable shield 115 and electronic housing 105. In some exemplary embodiments, cable clamp 120 may be electrically coupled to electronic housing 105 via cable shield 115 and gasket 110. For example, for shielded Ethernet cables, a braided shield may be included around multiple conductors. Typically, the braided shield is covered by an insulating sheath, such as PVC or polyurethane. A portion of the insulating sheath may be removed to expose the braided shield, which is then electrically coupled to cable clamp 120. In some exemplary embodiments, the cable clamp 120 can be electrically connected to the braided shield by clamping the cable 125 at the location of the exposed braided shield. In this configuration, the cable clamp 120 and the cable 125 can be configured such that the cable clamp 120 is electrically connected to the shield or grounding of the cable 125, thereby connecting any unwanted electromagnetic noise from the cable to an electrical grounding point, such as an engine block or the like. This configuration advantageously reduces electromagnetic interference coupled to other electronic components within the PCB or electronic housing 105.

[0040] Now turn to Figure 2 The image shows a cross-section of an exemplary configuration 200 for an improved high-voltage connector thermal, impact, and vibration cable shield 215 according to various embodiments. The exemplary configuration 200 shows an electronic housing 205, a PCB 207, a cable shield 215, a cable shield flange 217, multiple mechanical fasteners 219, a shielding gasket 210, a cable clamp 220, a cable 225, and an electrical connector 209.

[0041] In some exemplary embodiments, the electronic housing 205 may be a liquid-cooled metal structure configured to isolate the PCB 207 from environmental contaminants such as moisture, dust, electromagnetic interference, heat, and the like. In automotive applications, the electronic housing 205 may be configured to be mechanically and electrically connected to the engine block or other engine compartment surfaces. In some exemplary embodiments, the electronic housing may include an electric supercharger controller and / or a power supply.

[0042] PCB 207 is configured to transmit and receive electrical signals and / or current to external components via cable 225. In some exemplary embodiments, the cable is a high-current cable for conducting current to an electric motor. Along with other electronic components such as resistors, capacitors, diodes, and integrated circuits, PCB 207 may be configured with connectors 209 for mechanical connection to a cable connector coupled to cable 225. It is desirable to reduce vibration and movement of the cable connector to prevent degradation of the connector contact coating and damage to the connector 209 attached to PCB 207. Typically, connector 209 has multiple conductive pins that are soldered into vias or holes formed in PCB 207 to create a reliable electrical connection. However, these soldered connectors are susceptible to damage from external forces on connector 209, which may damage the pins, the solder joints at the interface of connector 209 and / or PCB 207. To achieve this, a cable shield 215 integrated with cable clamps is configured to restrict movement of cable 225 and provide an environmental barrier between the surrounding environment and connector 209.

[0043] The cable shield 215 can be mechanically secured to the electronic housing 205 via one or more mechanical fasteners 219. In some exemplary embodiments, the mechanical fasteners can be positioned through holes in the cable shield flange 217, into threaded holes formed and / or tapped in the electronic housing 205. When fully positioned in the threaded holes, the mechanical fasteners 219 apply a force to the cable shield flange 217 toward the electronic housing 205. In some exemplary embodiments, a shielding gasket 210 can be positioned between the electronic housing 205 and the cable shield flange 217, thereby forming a barrier against dust, dirt, moisture, and heat between the cable shield 215, the cable shield flange 217, and the electronic housing 205. The force generated by the mechanical fasteners 219 can hold the shielding gasket 219 and / or compress the shielding gasket 210, thereby achieving an environmental barrier.

[0044] Cable clamp 220 may be configured to apply clamping pressure to cable 225 to reduce induced vibration at connector 209 and to reduce lateral torque between cable 225 and connector 209. In some exemplary embodiments, cable clamp 220 may be electrically coupled to braided shielding or other conductive barriers inside cable 225 to provide a grounding connection from the conductive barrier to electronic housing 205 or other grounding point, thereby preventing unwanted electromagnetic energy from reaching PCB 207 and damaging connector 209 or electronic components, or disrupting circuit operation.

[0045] Now turn to Figure 3The image shows a cross-sectional view 300 of a cable shield 315 for an improved high-voltage connector thermal, impact, and vibration cable shield 315 according to various embodiments. The exemplary cross-sectional view 300 shows an electronic housing 305, a cable shield 315, a cable shield flange 317, multiple mechanical fasteners 319, a shielding gasket 310, a cable 325, and multiple retaining ribs 340.

[0046] To further restrict cable movement, the cable shield 315 may be formed with one or more ribs 340 or protrusions formed within the cable shield 315. In the illustrated cross-sectional view and exemplary embodiment, three ribs 340 formed within the cable shield 315 are shown to hold the cable 325. These ribs restrict cable movement, thereby restricting cable connector movement and reducing the possibility of plating wear and / or connector damage. In some exemplary embodiments, these ribs are formed parallel to the cable length, or orthogonal to the cable shield flange 317, or may be formed perpendicular to the cable length, thereby generating the required insertion force applied to the cable during assembly. Parallel ribs can restrict cable movement within and outside the connector and limit rotational movement of the cable 325.

[0047] Now turn to Figure 4 A flowchart is shown, illustrating a non-limiting embodiment of a method 400 for providing an improved thermal, impact, and vibration cable shielding for a high-voltage connector in accordance with the teachings of this disclosure.

[0048] Method 400 first operates to insert a cable through and through a cable shield. In some exemplary embodiments, the cable shield is configured as a tube with an opening at each end. The cable is inserted into a first opening until it protrudes from a second opening. In some exemplary embodiments, the first opening is configured with a cable clamp, and the second opening is configured with a cable shield flange. The internal dimensions of the cable shield substantially correspond to the external dimensions of the cable. In some exemplary embodiments, the inner surface of the cable shield may include one or more ribs or protrusions to restrict rotational movement of the cable once it is inserted into the cable shield.

[0049] Once the cable has been inserted into the cable shield such that it extends from the second opening, the 415 connector is attached to the end of the cable protruding from the second opening of the cable shield. In some exemplary embodiments, the connector is attached to the cable after the cable has been inserted through the cable shield, and the internal dimensions of the cable shield are smaller than the external dimensions of the cable connector. In some exemplary embodiments, where the cable connector size is smaller than the internal dimensions of the cable shield, the cable connector can be attached to the cable before the cable is inserted into the cable shield.

[0050] Once the cable connector is mounted on the cable and the cable with the connector protrudes from the cable shield, the cable connector engages with the PCB connector exposed from the electronic housing 420. In some exemplary embodiments, the PCB connector is electrically or communicatively connected to the PCB via a cable inside the electronic housing or by soldering the PCB connector directly to the PCB. In some exemplary embodiments, the cable connector is a plastic connector that is press-fitted into a corresponding plastic PCB connector. Each of the PCB connector and the cable connector may include part of a locking mechanism, such as a spring-loaded snap and locking protrusion for position assurance and engagement retention after installation engagement.

[0051] After the connector is engaged, the cable shield can be slid over the connector interface and mechanically fastened 425 to the electronic housing. Mechanical fastening can be achieved by a bolt passing through a hole in the cable shield flange and screwing into and tightening into a corresponding threaded hole in the electronic housing to establish a rigid connection between the cable shield and the electronic housing. A gasket may be located between the electronic housing and the cable shield flange to provide additional environmental and / or thermal isolation between the connector and the surrounding environment. Additionally, the gasket material can be selected to improve or inhibit thermal and / or electrical conduction between the cable shield and the electronic housing. In some exemplary embodiments, the outer surface of the cable shield may include threads for screwing into a corresponding hole in the electronic housing, the corresponding hole having internal threads and exposing the electrical connector (making the electrical connector exposed). In these embodiments, threaded fasteners will not be used because the cable shield itself is screwed into the corresponding hole in the electronic housing.

[0052] Once the cable shield is rigidly attached to the electronic housing, the cable clamp near the first opening tightens 430° onto the cable. The cable clamp can be a saddle clamp or similar and can be electrically connected to the cable's braided shield. The cable clamp restrains the cable at its position to reduce vibration at the connector interface and minimize other harmful physical movement of the cable.

[0053] While at least one exemplary embodiment has been presented in the foregoing detailed embodiments, it should be understood that many variations exist. It should also be understood that one or more exemplary embodiments are merely examples and are not intended to limit the scope, applicability, or construction of this disclosure in any way. Rather, the foregoing detailed embodiments will provide those skilled in the art with a convenient roadmap for implementing exemplary embodiments of this disclosure. It should be understood that various changes may be made to the function and arrangement of the elements described in the exemplary embodiments without departing from the scope of this disclosure, for example, as set forth in the appended claims.
