Description

Technical Field

[0001] This utility model relates to the field of charging terminals, and more specifically to a short-circuit-proof insulation structure for charging terminals. Background Technology

[0002] Charging terminals are key components of connector interfaces, serving as crucial for data and power transmission between electronic devices. They are widely used in various technological fields and play an indispensable role. Their main application areas include, but are not limited to, consumer electronics, computers and peripherals, automotive electronics, communication and network equipment, and industrial and automation control. Terminals enable signal transmission and power supply between devices and peripherals, acting as an important bridge for information exchange between them.

[0003] Existing terminal insulation structures typically consist of an insulator and metal contacts. The insulator is usually made of high-temperature and corrosion-resistant engineering plastics, such as polyimide and polyamide, while the metal contacts are usually made of metals with good conductivity, such as copper or copper alloys.

[0004] However, existing terminal insulation structures still have some obvious defects. With the increasing prevalence of charging scenarios for various electronic devices, the safety of charging terminals is of paramount importance. Traditional charging terminal insulation designs have many shortcomings, often leading to serious problems due to inadequate insulation protection. On the one hand, during the use, storage, or transportation of equipment, adjacent pins of the terminals are prone to contact due to vibration, collision, or other unexpected situations. A momentary short circuit can damage the charger and battery, or even cause smoke and fire, endangering personal and property safety. On the other hand, in complex environments such as humid and dusty conditions, moisture and dust can easily enter the terminal connector, causing short circuit faults, affecting the normal charging and use of the equipment, and thus affecting the service life of the equipment. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned deficiencies and provide a short-circuit-proof insulation structure for charging terminals. This solves the technical problem in the background art where the insulation structure provides poor protection for connector terminals, leading to short circuits on the pins and affecting the normal use of the equipment.

[0006] The objective of this utility model is achieved through the following means:

[0007] A short-circuit-proof charging terminal insulation structure includes a charging interface, which consists of a housing and a terminal body disposed within the housing. The terminal body is bent to form pins for soldering, with one end of the pin extending downward through the housing. A fixed end is formed on the side of the housing by bending. An insulating shell is provided on the housing, including an insulating upper cover and an insulating lower cover. The insulating upper cover and the insulating lower cover are plugged and mated together, so that the insulating upper cover and the insulating lower cover are mated and wrapped around the top and bottom of the housing. A clearance slot is provided in the insulating lower cover for the pin to pass through. A removable insulating sleeve is provided in the clearance slot. The pin can pass through the insulating sleeve and into the clearance slot, extending downward through the bottom of the insulating lower cover. The insulating sleeve is fitted onto the pin and forms a protective wrapping layer. An installation slot is provided in the insulating lower cover. The fixed end is mated and inserted into the installation slot through a plug-in sleeve. The end of the fixed end extends downward through the installation slot and extends downward through the bottom of the insulating lower cover.

[0008] Furthermore, as described above, the interior of the insulating upper cover and the insulating lower cover are respectively formed with upper and lower grooves for the top and bottom of the mating housing.

[0009] By creating grooves specifically designed for mating housings inside the insulating top and bottom covers, the housings are ensured to be tightly and securely encased. This enhanced insulation protection of the housings also effectively prevents contact between adjacent pins due to accidental events such as vibration or impact, thereby avoiding the risk of momentary short circuits and further improving the insulation protection of the housings.

[0010] Furthermore, as described above, the bottom of the insulating upper cover has a raised insertion protrusion, and the top of the insulating lower cover has a limiting groove for mating with the insertion protrusion. The insulating upper cover is mated and inserted with the insertion protrusion and the limiting groove.

[0011] The mating design of the insertion protrusion and the limiting groove makes the connection between the insulating upper cover and the insulating lower cover more secure and reliable. This improves the overall stability of the insulation structure and also helps prevent external impurities such as moisture and dust from entering the terminal connector through the connection gaps, effectively avoiding short circuits caused by humid and dusty environments and extending the service life of the equipment.

[0012] Furthermore, as described above, one end of the clearance slot and the mounting slot communicates with the lower groove and extends through to the bottom of the insulating lower cover.

[0013] The clearance slot and mounting slot communicate with the lower recess, providing guidance for the installation of pins and fixed ends. Simultaneously, the sealing and embedding of insulating sleeves and plug sleeves within the clearance slot and mounting slot further enhances insulation protection.

[0014] Furthermore, as described above, a pad is adhered to the lower groove, and sealant is adhered to the joint between the insulating upper cover and the insulating lower cover.

[0015] The padding increases the contact area between the lower groove and the housing, improving the stability and sealing of the insulation structure. The sealant further enhances the seal between the upper and lower insulating covers, effectively preventing the intrusion of moisture, dust, and other external impurities, thus further improving the protective capabilities of the insulation structure and the service life of the equipment.

[0016] Furthermore, as described above, the bottom of the insulating sleeve is formed into a cone shape, and the insulating sleeve is inserted and paired with the clearance slot. A connection through hole for the pairing pins is formed inside the insulating sleeve.

[0017] The tapered insulating sleeve design ensures a tighter and more reliable connection with the clearance slot, contributing to improved overall insulation stability and sealing. Simultaneously, the through-hole design ensures proper connection between the pins and the connector, while the insulating sleeve itself provides excellent insulation protection, further reducing the risk of short circuits caused by pin contact.

[0018] The beneficial effects of this utility model are as follows: The terminal body is installed inside the housing, and one end of the terminal body is bent to form a pin for soldering. One end of the pin extends downward through the housing, allowing the terminal body to be connected to components such as circuit boards. The fixed end of the housing is used to fix it to electronic equipment. The plug-in mating connection of the insulating upper cover and the insulating lower cover forms a complete insulating shell, which can cover the top and bottom of the housing, reducing the interference of the external environment on the internal charging interface, reducing the penetration of moisture, dust and other impurities into the housing, avoiding the risk of short circuit of the terminal body, and the avoidance slot allows the pin to pass smoothly through the insulating lower cover to meet the pin connection requirements. At the same time, the design of the insulating sleeve provides additional insulation protection for the pin, effectively preventing short circuits caused by vibration contact between pins or other reasons. The plug-in sleeve further improves the sealing performance of the fixed end passing through the mounting slot, enhancing the insulation protection effect of the internal components of the housing and the overall service life.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] In this embodiment, refer to Figures 1-5 The specific implementation of the short-circuit protection charging terminal insulation structure includes a charging interface, which consists of a housing 1 and a terminal body 2 disposed within the housing 1. The terminal body 2 is bent to form four pins 3 for soldering. One end of each pin 3 extends downward through the housing 1. Two fixed ends 4 are formed on the two sides of the housing 1 by bending. An insulating shell 1 is provided on the housing 1, which includes an insulating upper cover 5 and an insulating lower cover 6. The insulating upper cover 5 and the insulating lower cover 6 are plugged into each other for mating. The top and bottom of the housing 1 are covered by an insulating lower cover 6, which has a clearance slot 7 for the pin 3 to pass through. A removable insulating sleeve 8 is provided in the clearance slot 7. The pin 3 can pass through the insulating sleeve 8 and into the clearance slot 7 to extend to the bottom of the insulating lower cover 6, so that the insulating sleeve 8 is fitted on the pin 3 and forms a protective layer. An installation slot 9 is provided in the insulating lower cover 6. The fixed end 4 is paired with the installation slot 9 through the plug sleeve 10. The end of the fixed end 4 extends to the bottom of the insulating lower cover 6 through the installation slot 9.

[0027] The interior of the insulating upper cover 5 and the insulating lower cover 6 are respectively formed with upper grooves 11 and lower grooves 12 for the top and bottom of the mating housing 1.

[0028] By forming grooves specifically for mating housing 1 inside the insulating upper cover 5 and insulating lower cover 6, it can be ensured that housing 1 is tightly and securely encased. This enhances the insulation protection of housing 1 and effectively prevents adjacent pins 3 from contacting due to accidental conditions such as vibration and impact, thereby avoiding the risk of instantaneous short circuit and further improving the insulation protection effect of housing 1.

[0029] Specifically, the upper groove 11 and the lower groove 12 are matched with the top and bottom of the housing 1, so that the installed insulating upper cover 5 and insulating lower cover 6 are wrapped around the housing 1, and the insulating upper cover 5 and insulating lower cover 6 can protect the housing 1.

[0030] The bottom of the insulating upper cover 5 has a raised insertion protrusion 13, and the top of the insulating lower cover 6 has a limiting groove 14 for matching the insertion protrusion 13. The insulating upper cover 5 is matched and inserted with the limiting groove 14 through the insertion protrusion 13.

[0031] The mating design of the insertion protrusion 13 and the limiting groove 14 makes the connection between the insulating upper cover 5 and the insulating lower cover 6 more secure and reliable. This improves the overall stability of the insulation structure and also helps prevent external impurities such as moisture and dust from entering the terminal connector through the connection gaps, effectively avoiding short-circuit faults caused by humid and dusty environments and extending the service life of the equipment.

[0032] Specifically, in some embodiments, the insulating upper cover 5 and the insulating lower cover 6 can be plugged in and paired by snaps to complete the wrapping connection of the charging interface.

[0033] One end of the clearance slot 7 and the mounting slot 9 is connected to the lower groove 12 and extends through to the bottom of the insulating lower cover 6.

[0034] The clearance slot 7 and the mounting slot 9 communicate with the lower groove 12, providing guidance for the installation of the pin 3 and the fixed end 4. At the same time, the insulation protection is further improved by the sealing and embedding of the insulating sleeve 8 and the plug sleeve 10 provided in the clearance slot 7 and the mounting slot 9.

[0035] Two pads 15 are bonded inside the lower groove 12, and sealant (not shown) is bonded at the joint between the insulating upper cover 5 and the insulating lower cover 6.

[0036] The pad 15 increases the contact area between the lower groove 12 and the housing 1, improving the stability and sealing of the insulation structure. The bonding of the sealant further enhances the sealing effect between the upper insulating cover 5 and the lower insulating cover 6, effectively preventing the intrusion of external impurities such as moisture and dust, thereby further improving the protective capability of the insulation structure and the service life of the equipment.

[0037] Specifically, the sealant is adhered to the bottom of the insulating upper cover 5 and is arranged around the insertion protrusion 13, filling the gap between the insulating upper cover 5 and the insulating lower cover 6.

[0038] The bottom of the insulating sleeve 8 is formed into a cone shape. The insulating sleeve 8 is inserted and paired with the clearance slot 7. A connection through hole 16 for the pairing pin 3 is formed inside the insulating sleeve 8.

[0039] The conical design of the insulating sleeve 8 ensures a tighter and more reliable connection with the clearance slot 7, contributing to improved overall insulation stability and sealing. Simultaneously, the through-hole 16 ensures proper connection between the pin 3 and the connector, while the insulating sleeve 8 itself provides excellent insulation protection, further reducing the risk of short circuits caused by pin 3 contact.

[0040] Specifically, the insulating sleeve 8 and the plug sleeve 10 are both made of highly elastic, high-temperature resistant and wear-resistant insulating rubber material, and can fit tightly against the pin 3 and the fixed end 4. The insulating upper cover 5 and the insulating lower cover 6 are injection molded from high-strength insulating plastic.

[0041] The specific connection structure in this embodiment is as follows:

[0042] The terminal body 2 is installed inside the housing 1, and one end of the terminal body 2 is bent to form a pin 3 for soldering. One end of the pin 3 extends downward through the housing 1, allowing the terminal body 2 to connect to components such as circuit boards. The fixing end 4 of the housing 1 is used to fix it to electronic equipment. An insulating sleeve 8 is fitted onto the pin 3. The insulating lower cover 6 is paired with the bottom of the housing 1, so that the insulating sleeve 8 is embedded in the clearance slot 7, and the pin 3 extends downward through the clearance slot 7 to the bottom of the insulating lower cover 6. The insulating upper cover 5 is fastened and installed on the top of the housing 1. At the same time, the insulating upper cover 5 mates with the limiting groove 14 of the insulating lower cover 6 through the insertion protrusion 13, so that... The insulating upper cover 5 and the insulating lower cover 6 are connected by plugging to form a complete insulating shell 1, which can cover the top and bottom of the shell 1, reduce the interference of the external environment on the internal charging interface, reduce the phenomenon of water vapor, dust and other impurities penetrating into the shell 1, and avoid the risk of short circuit of the terminal body 2. The design of the insulating sleeve 8 provides additional insulation protection for the pins 3, effectively preventing short circuits caused by vibration contact between the pins 3 or other reasons. Furthermore, the plug-in sleeve 10 is connected to the fixed end 4, and the plug-in sleeve 10 is embedded in the mounting slot 9, which further improves the sealing performance of the fixed end 4 passing through the mounting slot 9, enhances the insulation protection effect of the internal components of the shell 1 and the overall service life.
