[0002] In the field of electrical connection technology, in order to ensure the convenience of production and assembly, high-voltage cables, like traditional low-voltage wiring harnesses, need to use connectors for assembly and connection. For example, new energy vehicles use high-voltage cables for high-voltage power transmission to achieve power transmission. At present, the IRPT through-hole connector structure has an output angle of 180°, as recorded in CN202022483654.8. With the development of the new energy industry, there are more and more demands for adjusting the output angle and multi-angle output. The IRPT through-hole connector has a single output direction and is limited by the structure, so it cannot meet the multi-angle output requirements.

[0003] The existing adjustment of the lead-out angle usually adopts a switching solution and multiple components, which has the following defects: first, the switching solution uses more components, and multiple installation processes are required during assembly, which increases the cost of parts, mold costs, and labor costs; second, the contact resistance of the power component switching is unstable, and the contact resistance will change accordingly, which increases the proportion of installation risks (such as excessive temperature rise, burning arcing, etc.), and also increases the proportion of assembly risks. Utility Model Content

[0008] In some embodiments, a plurality of reinforcing ribs are integrally formed on the circumferential wall of the curved pipe in a radially outward direction.

[0009] In some embodiments, the width of the reinforcing rib plates located in the bending plane is greater than the width of the remaining reinforcing rib plates.

[0013] In some embodiments, the inner connection surface of the connection seat is further processed with a plurality of process grooves.

[0014] In some embodiments, a first sealing ring is provided between the front end cover and the positioning ring of the elbow.

[0027] Figures 1 to 5 A curved via connector according to an embodiment of the present disclosure is schematically shown. As shown in the figure, the device comprises a housing 1, a front cover 2 and a rear cover 3;

[0028] The housing 1 includes an integrally formed connection seat 10 and a high temperature resistant elbow 11, and the elbow 11 can be bent to the angle required for the installation condition;

[0029] The front cover 2 and the rear cover 3 are respectively connected to the front and rear ends of the curved pipe 11 to form a curved wire-passing channel, through which the stripped end of the curved cable 4 can pass and be sealed and fixed.

[0030] When the curved through-hole connector is used, the housing 1, the front cover 2 and the rear cover 3 are disassembled, and the end of the cable 4 is peeled and passed through the rear cover 3, the center hole of the curved tube 11 and the front cover 2 in sequence, and then assembled into one body, and the cable 4 is sealed and fixed in the wire-passing channel formed by the three. Its beneficial effects are: first, the device realizes the outlet of multiple bending angles, and the outlet angle can be adjusted at any time according to the working conditions; second, the structure is simple, the number of parts is small, the cost is saved, and the panel space is small; third, the assembly process is simplified, and the on-site installation operation is convenient. The housing 1 with various bending angles is processed in large quantities and high precision in the factory. The on-site assembly only needs to select the housing 1 with a suitable bending angle. The tooling and fixture are basically not used on site, and the transfer and the assembly of other parts to meet the bending angle are saved, which improves the on-site installation efficiency and has higher installation accuracy; fourth, the structure is safe to install and use. The structure is an integrated assembly solution, which saves the transfer procedure, has no contact resistance change, no risk such as excessive temperature rise and burning electric arc, and the risk coefficient of electrical performance is low.

[0031] Furthermore, a plurality of reinforcing ribs 12 are integrally formed radially outwardly on the circumferential wall of the curved tube 11. The beneficial effect is that the reinforcing ribs 12 can improve the bending performance of the curved shell 1, so that the curved tube 11 has the performance of maintaining the bending angle without deformation.

[0032] Preferably, the width of the reinforcing rib plate 12 located on the bending plane is greater than the width of the other reinforcing rib plates 12. The beneficial effect is that the reinforcing rib plate 12 is matched with the bending load at each location of the bent pipe 11, so that the bending performance of the bent pipe 11 is further improved, so that the bent pipe 11 can better maintain the bending angle without deformation.

[0033] Preferably, the bent pipe 11 is made of high temperature resistant nylon plastic material. The beneficial effect is that the bent pipe 11 made of this material has better high and low temperature resistance and will not deform.

[0034] Furthermore, the connection base 10 is provided with a plurality of first through holes 13 around it and the inner connection surface is provided with positioning posts 14.

[0036] Preferably, Figure 5 As shown, the inner connection surface of the connection seat 10 is also processed with a plurality of process grooves 15. The beneficial effect is that the process grooves 15 can reduce the material and reduce the weight of the housing 1, and the reasonable configuration of the process grooves 15 can optimize the load-bearing performance of the connection seat 10.

[0037] Furthermore, a first sealing ring 8 is provided between the front end cover 2 and the positioning ring of the elbow 11.

[0038] A sealing body 9 is provided between the rear end cover 3 and the positioning groove of the elbow 11. Preferably, the sealing body 9 can be a sealing ring. The beneficial effect is that the sealing body 9 and the first sealing ring 8 can seal the cable stripping end to prevent impurities, water vapor or sparks from entering the environment.

[0039] Furthermore, an outer shielding sleeve 6 is provided between the cylindrical cover body of the front end cover 2 and the inner wall of the front port of the curved tube 11, and an inner shielding sleeve 7 is installed outside the stripped wire harness of the cable 4, and the inner end of the outer shielding sleeve 6 is sleeved outside the inner shielding sleeve 7. The beneficial effect is that the improved through-hole connector makes the cable 4 resistant to high voltage and self-shielded, and the electrical performance risk is low during use.

[0040] Furthermore, the front and rear ports of the curved pipe 11 and the front cover 2 and the rear cover 3 are arranged by clamping or crimping. The beneficial effects are: good clamping positioning and convenient installation.

[0041] Preferably, after the end of the cable 4 is stripped, it is passed through the rear end cover 3, the center hole of the elbow 11 and the front end cover 2 in sequence. After being assembled into one, the shield is first crimped, and then ultrasonic welding or terminal crimping is performed. This product has a simple structure and is easy to assemble, eliminating the need for switching and the need to assemble other components to meet the angle.

[0042] Preferably, the front end cover 2 includes a hollow cylindrical first cover body, a circular sealing disk 21 is formed at the front end of the first cover body, and a plurality of sheet-foot-shaped external clamping ends 22 are formed on the outer edge of the sealing disk 21. The first cover body is inserted into the front port of the cable 4, and the outer shielding sleeve 6 and the front end cover 2 are clamped, and the external clamping end 22 fits the sealing body 9.

[0043] The angle of the curved connector is determined according to the installation conditions. The cable bending is designed according to the minimum bending radius of the corresponding specifications. For example, the diameter of a 35 square millimeter shielded cable is 10.5 mm, and the minimum bending radius is 4×D, then the minimum bending radius of the cable is 42 mm.

[0044] The above are only some embodiments of the present disclosure. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present disclosure, which all belong to the protection scope of the present disclosure.
