Description

Technical Field

[0001] The present invention relates to an electrical connection device, and more specifically, to an angled connector, the application scenarios of which include high-voltage connectors on new energy vehicles. Background Art

[0002] Currently, the trend in the automotive industry is for new energy vehicles (including pure electric vehicles and hybrid vehicles) to replace traditional fuel vehicles. The electrical and electronic architecture (EEA) of new energy vehicles differs significantly from that of traditional fuel vehicles. Consequently, many connectors in the EEA of new energy vehicles are different from, or not used in, the EEA of traditional fuel vehicles. For example, the EEA of new energy vehicles often includes high-voltage connectors.

[0003] High-voltage connectors, also known as high-voltage plug-ins, generally refer to connectors with an operating voltage of 60V or above and are primarily responsible for transmitting high currents. They are primarily used in the high-voltage, high-current circuits of electric vehicles, acting alongside conductors to transmit the battery pack's energy through various electrical circuits to various components within the vehicle system, such as the motor controller, DC-DC converter, and charger. Due to the high-voltage operating environment, high-voltage connectors must meet specific performance specifications for heat resistance, pressure resistance, current carrying capacity, and EMC.

[0004] For example, the Chinese patent with authorization announcement number CN210576875U discloses a 90° elbow connector, a plug assembly, and a socket assembly. The plug housing on the plug assembly and the socket housing on the socket assembly cooperate and are tightly coupled. After connection, the signal terminal and the signal jack are connected to each other to achieve signal transmission. However, since one of the development trends of new energy vehicles is high integration and lightweight, the requirements for internal space are constantly increasing. In order to adapt to different wiring spaces, connectors need to be able to more accurately adapt to different cable access angles, such as 45 degrees, 60 degrees, etc. Therefore, the demand for connectors with different angles is gradually increasing. In addition, the industry uses the connection between the terminal and the reed to play a conductive role and realize signal transmission. However, the stability of the terminal and the reed after connection is limited. Because the pre-tightening force between the connected terminal and the reed is limited, the connection makes the terminal and the reed movable, which leads to a large contact resistance. As the temperature on the terminal and the reed rises, the mechanical properties will decline, and the temperature rise will gradually increase. That is to say, the temperature of each component in the electronic and electrical equipment will gradually increase above the environment, and the conductive performance will also be relatively reduced, causing the entire elbow connector to be in a long-term thermal fatigue state. Long-term thermal fatigue causes the performance of the elbow connector to decrease. Summary of the Invention

The assembly is simple and convenient, greatly improving work efficiency.

[0029] The setting of the flip cover waterproof ring reduces the possibility of water and dust entering. In addition, locking through the connecting bolts can greatly improve the sealing effect and enhance safety.

[0032] The cable waterproof ring reduces the possibility of water and dust intrusion, significantly improving the sealing effect and enhancing safety. Furthermore, the tail cap protrusion is elastically positioned within the tail cap opening, completing the installation and positioning of the two-core tail caps.

[0043] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0044] like Figures 1 to 6 As shown, the present invention discloses an angled connector comprising an outer housing 1 integrally formed from an aluminum alloy. Compared to conventional welding processes, the integral formation of the outer housing 1 reduces the strength weaknesses of conventional welding processes, improves structural rigidity and collision energy absorption, optimizes engineering design, achieves more uniform stress distribution, and extends service life. Furthermore, the outer housing 1 is preferably made of aluminum alloy due to its lightweight, low cost, corrosion resistance, and flexible processing properties. However, the outer housing 1 may also be made of other materials and still fall within the scope of protection of the present invention.

[0045] In the present invention, the outer shell 1 is composed of a horizontal shell 11 and an inclined shell 12. There is an angle between the horizontal shell 11 and the inclined shell 12. In the preferred embodiment, the angle between the horizontal shell 11 and the inclined shell 12 is 110°. Of course, other angles, such as 130°, 150°, 60°, etc., are also possible and fall within the scope of protection of the present invention.

[0046] The horizontal shell 11 is provided with a receiving cavity, and the receiving cavity is provided with a main inner core 2 adapted thereto and fixed on the horizontal shell 11. The main inner core 2 has oppositely arranged side surfaces 21 and a top surface 22 and a bottom surface 23 located between the side surfaces 21. The side surfaces 21, top surface 22 and bottom surface 23 surround and form the receiving cavity, and a partition plate 24 is provided between the top surface 22 and the bottom surface 23 to divide the receiving cavity into two to form two receiving slots. A limit block 25 is fixed in each of the receiving slots, the outer side of the limit block 25 is fixed on the corresponding side surface 21 or partition plate 24, the top end of the limit block 25 is fixed on the top surface 22, and the end of the limit block 25 can abut against the vertical end 31 of the transfer copper busbar 3 to limit the axial position of the transfer copper busbar 3 moving forward.

[0047] A connecting rib 27 is fixed to the head end of the limit block 25, and a connecting plate 28 is fixed to the connecting rib 27. A U-shaped support plate 20 is fixed to the outside of the connecting plate 28. The end side of the support plate 20 is fixed to the side surface 21. The connecting plate 28 has a connecting port, and a connecting ring 29 is fixed to the connecting port. An extension arm 291 is fixed to the outer circumference of the connecting ring 29, and a locking block 292 is fixed to the extension arm 291.

[0048] A right-angled trapezoidal positioning block 26 is also fixed on the bottom surface 23, and the inclined surface of the positioning block 26 abuts against the inclined end 33 of the transfer copper bus 3. The upper surface of the positioning block 26 abuts against the horizontal end 32 of the transfer copper bus 3. The upper surface and inclined surface of the positioning block 26 can respectively play a positioning and supporting role for the horizontal end and the inclined end 33 of the transfer copper bus, providing it with stable mechanical support, uniformly dispersing stress, and extending its service life. Furthermore, the height of the horizontal end 32 is equal to the minimum distance between the positioning block 26 and the limit block 25, and the head end of the horizontal end 32 extends and is placed directly below the connecting ring 29, and a connecting hole 34 is provided on it. A locking groove 35 adapted to the locking block 292 is also provided on the horizontal end 32, and the locking block 292 can be extended and placed in the locking groove 35.

[0049] The above design is ingenious. The positioning block 26 and the limit block 25 cooperate with each other to achieve precise radial and axial positioning of the transfer copper busbar. This positioning method is simple, convenient, stable and reliable, and does not require other locking structures, thereby improving safety while minimizing costs. In addition, the locking block is snapped into the locking groove to prevent the transfer copper busbar from being displaced during the processing process, thereby improving stability and ensuring the processing yield, and has a wide applicability.

[0050] Furthermore, in a preferred embodiment, lightweight grooves are provided on the limit block 25 and the positioning block 26 to reduce the overall weight of the connector, thereby achieving lightweighting and reducing costs.

[0051] Positioning ribs 9 are also fixed to the outside of the top surface 22 and the bottom surface 23. The inner wall of the horizontal shell 11 is provided with positioning grooves that match the positioning ribs 9. Positioning openings 91 are provided at the head ends of the top surface 22 and the bottom surface 23. Positioning spring plates 92 fixed to the top surface 22 and the bottom surface 23 are located within the positioning openings 91. Positioning protrusions 93 are fixed to the ends of the positioning spring plates 92. During assembly, the positioning ribs 9 guide the sliding of the main inner core on the horizontal shell 11, ensuring its stability and accuracy. After sliding to the predetermined position, the positioning protrusions 93 abut against the horizontal shell 11 under the action of elastic force, thus achieving the installation and positioning of the main inner core. This makes assembly simple and convenient, greatly improving work efficiency.

[0052] The inclined shell 12 is provided with symmetrically arranged accommodating cavities, each of which is provided with an auxiliary inner core 4 adapted thereto and secured to the inclined shell 12. The auxiliary inner core 4 comprises at least a box body 42 having a hollow cavity 41. The box body 42 can be extended and placed within a slot 44 of the bottom surface 23. Support plates 43 are fixedly provided on both sides of the box body 42. The inner walls of the support plates 43 abut against the limit blocks 25, and the upper surfaces of the support plates 43 abut against the lower surface of the top surface 22. In the above, the support plates 43 abut against the limit blocks and the top surface, respectively, to achieve precise positioning of the auxiliary inner core 4. This compact structure eliminates the need for redundant auxiliary positioning structures, simplifies the overall structure, and facilitates a reasonable layout.

[0053] Furthermore, the box body 42 is provided with retaining ribs 45 on both sides, and the inner wall of the tilting housing 12 is provided with retaining grooves that mate with the retaining ribs 45. A retaining spring plate 46 is provided on the bottom surface of the box body 42, and a retaining bump 47 is fixed to the end of the retaining spring plate 46. The retaining ribs 45 guide the sliding of the box body 42 on the tilting housing 12, ensuring its stability and precision. Once the box body 42 slides to a predetermined position, the retaining bump 47, under the action of elastic force, abuts against the tilting housing 12, thereby achieving installation and positioning of the auxiliary inner core. This makes assembly simple and convenient, greatly improving work efficiency.

[0054] The auxiliary inner core 4 has a built-in connecting copper bar 5, one end of which is connected to the transfer copper bar 3 via a locking bolt 51. In this embodiment, the connecting copper bar 5 is directly fixedly connected to the transfer copper bar 3 via a locking bolt. The preload force between the connecting copper bar 5 and the transfer copper bar 3 fixed by the locking bolt 51 is large, the contact resistance is small, and the connection is stable and reliable, thereby making the temperature rise relatively low and stable. Under the same conditions, the connection method of the present application also relatively improves the conductive performance, avoids the performance degradation caused by long-term thermal fatigue, and solves the technical problems of movable contact between copper bar terminals, limited preload force, and large contact resistance in the prior art.

[0055] A latch seat 111 is fixed to the upper surface of the horizontal housing 11. A latch 112 is pivotally mounted on the latch seat 111. A flip cover 113 is fixed to the latch 112. A flip cover waterproof ring 115 is fixed to the bottom of the flip cover 113. The other end of the flip cover 113 is locked to the horizontal housing 11 via a connecting bolt 114. The provision of the flip cover waterproof ring 115 reduces the possibility of water and dust ingress. In addition, locking via the connecting bolt 114 significantly enhances the sealing effect and improves safety.

[0056] In this embodiment, a pressure ring 116 is fixed to the bottom of the horizontal housing 11, a pressure cover 117 is provided below the pressure ring 116, and a plug waterproof ring 118 is provided between the pressure ring 116 and the pressure cover 117. The provision of the plug waterproof ring 118 reduces the possibility of water and dust intrusion, greatly improving the sealing effect and enhancing safety.

[0057] The end of the main inner core 2 is provided with a rear cover shielding plate 6. The inner side of the rear cover shielding plate 6 abuts the main inner core 2, and its outer side abuts the rear cover waterproof ring 61. A rear cover 63 is provided on the outer side of the rear cover waterproof ring 61. A bent clip 64 extending inward is fixedly provided around the periphery of the rear cover 63. The inner wall of the bent clip 64 abuts the outer surface of the horizontal shell 11. The bent clip 64 defines a locking opening 65. The horizontal shell 11 is provided with a locking protrusion 66 that extends and fits within the locking opening 65. The provision of the rear cover waterproof ring 61 reduces the possibility of water and dust intrusion, significantly improving the sealing effect and enhancing safety. Furthermore, the locking protrusion 66 is elastically positioned within the locking opening 65, completing the installation and positioning of the rear cover. Assembly is simple and convenient, greatly improving work efficiency.

[0058] The other end of the connecting copper bus 5 is connected to the cable 7. In the present invention, the cable 7 and the connecting copper bus 5 are fixed by welding. Of course, other fixing methods can also be used, which all fall within the protection scope of the present invention.

[0059] The cable 7 is sleeved with a shielding crimping tube 71, which is sleeved with a shielding crown spring 72. A plug baffle 73 is installed on the end of the shielding crown spring 72 away from the connecting copper busbar 5. A two-core tail cap 74 is installed outside the plug baffle 73. A cable waterproof ring 75 is located between the two-core tail cap 74 and the plug baffle 73. An inwardly extending tail cap retaining plate 76 is installed outside the two-core tail cap 74. The inner wall of the tail cap retaining plate 76 abuts the outer surface of the inclined housing 12. The tail cap retaining plate 76 defines a tail cap opening 77. The inclined housing 12 is provided with a tail cap protrusion 78 that extends and fits within the tail cap opening 77. The provision of the cable waterproof ring 75 reduces the possibility of water and dust intrusion, significantly improving the sealing effect and enhancing safety. Furthermore, the tail cap protrusion 78 is elastically positioned within the tail cap opening 77, completing the installation and positioning of the two-core tail caps. Assembly is simple and convenient, greatly improving work efficiency.
