Description

Technical Field

[0001] This application relates to the field of electrical connection technology, and in particular to an anti-creep electrical connector. Background Technology

[0002] High-voltage connectors are critical electrical devices used to transmit high-voltage electrical energy. They possess excellent insulation, voltage withstand capability, and environmental adaptability, and are widely used in high-safety-requirement fields such as new energy vehicles, industrial equipment, and power systems. Their main function is to achieve reliable connection and disconnection between high-voltage circuits, ensuring efficient and stable power transmission while preventing dangerous phenomena such as leakage and arcing, thus ensuring the safety of equipment and personnel. They are an indispensable core component of modern electrical systems.

[0003] Creepage refers to the phenomenon where, under high voltage, dust, moisture, or contamination on the surface of insulating materials significantly reduces surface resistance, creating conductive paths in areas of concentrated electric field. This leads to leakage current and partial discharge. Over long periods, the insulation performance deteriorates, potentially forming carbonization pathways, ultimately causing short circuits, arcing, or fires between adjacent conductive components. It is a typical insulation failure mode and a major safety hazard in high-voltage electrical equipment.

[0020] 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.

[0021] The inventors discovered through analysis of existing technologies that existing high-voltage connectors, due to insufficient electrical clearance and creepage distance between terminals, are prone to creepage phenomena between adjacent terminals, posing a safety hazard.

[0022] Reference Figure 1-5 This illustration shows an anti-creep connector according to an embodiment of the present application, comprising: a wire end assembly 1 and a board end assembly 2; The wire end assembly 1 includes a first housing 11, and the first housing 11 is provided with a first port 12 and a second port 13; The plate end assembly 2 includes a second housing 21, a first terminal 22 and a second terminal 23. The first terminal 22 and the second terminal 23 pass through the second housing 21. The second housing 21 is provided with an isolation plate 24, which is disposed between the first terminal 22 and the second terminal 23. The first housing 11 is provided with an isolation groove 14 corresponding to the isolation plate 24, and the isolation groove 14 is disposed between the first port 12 and the second port 13; When the line end assembly 1 is connected to the plate end assembly 2, the first terminal 22 passes through the first port 12, the second terminal 23 passes through the second port 13, and the isolation plate 24 is disposed inside the isolation groove 14.

[0023] In the embodiments of this application, in view of the fact that existing high-voltage connectors are prone to creepage, this application provides a solution to set the terminals on different sides of the isolation plate 24 and the ports on different sides of the isolation groove 14, specifically including: a wire end assembly 1 and a plate end assembly 2; the wire end assembly 1 includes a first housing 11, the first housing 11 is provided with a first port 12 and a second port 13; the plate end assembly 2 includes a second housing 21, a first terminal 22 and a second terminal 23, the first terminal 22 and the second terminal 23 pass through the second housing 21, the second housing 21 is provided with an isolation plate 24, the isolation plate 24 is disposed between the first terminal 22 and the second terminal 23; the first housing 11 is provided with an isolation groove 14 corresponding to the isolation plate 24, the isolation groove 14 is disposed between the first port 12 and the second port 13; when the wire end assembly 1 is connected to the plate end assembly 2, the first terminal 22 passes through the first port 12, the second terminal 23 passes through the second port 13, and the isolation plate 24 is disposed inside the isolation groove 14. This application achieves anti-creep between terminals by setting up an insertion structure of isolation plate 24 and isolation groove 14.

[0024] The following will further describe an anti-creep connector in this exemplary embodiment.

[0025] It should be noted that the first port 12 and the second port 13 can be through holes penetrating the first housing 11 for accommodating wire terminals; the first terminal 22 and the second terminal 23 are plate terminals; when the wire terminal assembly 1 is connected to the plate terminal assembly 2, the plate terminal is used for electrical connection with the wire terminal. The isolation plate 24 can effectively block the surface discharge path between the first terminal 22 and the second terminal 23, increase the creepage distance, and prevent the risk of short circuit caused by voltage breakdown or arc. The isolation groove 14 can increase the creepage distance between the board terminals and also form a corresponding plug-in structure with the isolation plate 24 to increase the stability of the connection.

[0026] In one embodiment of this application, the isolation plate 24 is disposed inside the accommodating cavity of the second housing 21; The accommodating cavity of the second housing 21 is provided with a first guide groove 211 and a second guide groove 212; the first guide groove 211 and the second guide groove 212 are respectively disposed on both sides of one side of the isolation plate 24; The first housing 11 is provided with a first protrusion 111 corresponding to the first guide groove 211 and a second protrusion 112 corresponding to the second guide groove 212; the first protrusion 111 and the second protrusion 112 are respectively disposed on different sides of the isolation groove 14; When the line end assembly 1 is connected to the plate end assembly 2, the first port 12 and the second port 13 are disposed inside the accommodating cavity of the second housing 21, the first protrusion 111 is disposed inside the first guide groove 211, and the second protrusion 112 is disposed inside the second guide groove 212.

[0027] It should be noted that by providing the first guide groove 211 and the second guide groove 212 on only one side of the isolation plate 24, the accommodating cavity of the second housing 21 can form a longitudinally asymmetrical female end structure to prevent misinsertion.

[0028] In one embodiment of this application, the accommodating cavity of the second housing 21 is provided with a third guide groove 213 on the side near the first terminal 22; The side of the first port 12 is provided with a third protrusion 113 corresponding to the third guide groove 213; When the line end assembly 1 is connected to the plate end assembly 2, the third protrusion 113 is disposed inside the third guide groove 213.

[0029] It should be noted that, relative to the first guide groove 211 and the second guide groove 212, by providing the third guide groove 213 only on the side close to the first terminal 22, the receiving cavity of the second housing 21 can form a laterally asymmetrical female end structure to prevent misinsertion.

[0030] In one embodiment of this application, the first housing 11 is provided with a first limiting and blocking part 114; the first limiting and blocking part 114 is connected to the first protrusion 111 and the second protrusion 112; When the line end assembly 1 is connected to the plate end assembly 2, the first limiting blocking part 114 abuts against the side of the second housing 21 near the first guide groove 211 and the second guide groove 212.

[0031] It should be noted that the first limiting and blocking part 114 can prevent excessive insertion between the line end assembly 1 and the plate end assembly 2.

[0032] In one embodiment of this application, the first housing 11 is provided with a second limiting blocking part 115 and a third limiting blocking part 116; the second limiting blocking part 115 and the third limiting blocking part 116 are respectively disposed on both sides of the first limiting blocking part 114. When the line end assembly 1 is connected to the plate end assembly 2, the second limiting blocking part 115 and the third limiting blocking part 116 abut against the second housing 21.

[0033] It should be noted that the second limiting blocking part 115 and the third limiting blocking part 116 can utilize the abutment space on both sides of the first guide groove 211 and the second guide groove 212 in the second housing 21 to prevent over-insertion and ensure the strength of the limiting structure.

[0034] In one embodiment of this application, the first protrusion 111 is provided with a first abutting strip 1111; the second protrusion 112 is provided with a second abutting strip 1121; When the line end assembly 1 is connected to the plate end assembly 2, the first abutting strip 1111 abuts against the inner wall of the first guide groove 211, and the second abutting strip 1121 abuts against the inner wall of the second guide groove 212.

[0035] It should be noted that the first abutment strip 1111 and the second abutment strip 1121 can abut against the inner wall of the second housing 21 when the insertion is completed, thereby increasing the stability of the insertion.

[0036] In one embodiment of this application, one end of the first abutment strip 1111 is connected to the first protrusion 111 via a first slope structure 1112; one end of the second abutment strip 1121 is connected to the second protrusion 112 via a second slope structure 1122.

[0037] It should be noted that, since the first housing 11 and the second housing 21 are in a clearance fit when they are first inserted, the first slope structure 1112 and the second slope structure 1122 can serve as transition structures for insertion, so that the first abutment strip 1111 and the second abutment strip 1121 can smoothly enter the inner side of the second housing 21.

[0038] In one embodiment of this application, the accommodating cavity of the second housing 21 is provided with a first heat dissipation hole 214 and a second heat dissipation hole 215; the first heat dissipation hole 214 and the second heat dissipation hole 215 are respectively disposed on different sides of the isolation plate 24.

[0039] It should be noted that by setting the first heat dissipation hole 214 and the second heat dissipation hole 215 on different sides of the isolation plate 24, heat can be dissipated from the cavity where the corresponding plate end terminal is located.

[0040] In one embodiment of this application, a positioning piece 3 is also included; the side of the second housing 21 is provided with a positioning slot 216 corresponding to the positioning piece 3; the positioning piece 3 passes through the positioning slot 216.

[0041] It should be noted that the positioning piece 3 is used to mate with holes or slots on the substrate to ensure that the connector is positioned accurately during installation.

[0042] In one embodiment of this application, it further includes: a TPA component 4; the TPA component 4 is disposed through the first port 12 and the second port 13.

[0043] It should be noted that TPA (Terminal Position Assurance) is a secondary locking device used to ensure that the terminals inside the connector are correctly and securely installed. When the first port 12 and the second port 13 are provided with wire terminals, the TPA component 4 can limit the wire terminals in the first port 12 and the second port 13.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
