Description

Technical Field

[0001] This utility model relates to the field of connector technology, and specifically to a multifunctional six-core connector. Background Technology

[0002] To meet the needs of multi-circuit transmission, functional integration, and safety redundancy in complex electrical systems, multi-core high-voltage connectors have emerged. The "core" of a high-voltage connector is essentially an independent conductive terminal, with each "core" corresponding to one electrical circuit. Multiple "cores" are combined to achieve integrated design of multiple electrical circuits, simplifying wiring and reducing internal space requirements.

[0003] In the high-voltage systems of new energy vehicles, besides the need for space-saving structures, the safety of the high-voltage connectors themselves is extremely important. Therefore, the reliability and stability of connections between multiple cables, and the requirement for multiple electrical circuits, necessitate addressing the urgent issue of ensuring the safe use of high-voltage connectors while meeting the demands of reasonable wiring. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multifunctional six-core connector.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A multi-functional six-pin connector includes a plug and a socket that can be mated together. The plug housing contains a plug core and a first shielding layer. The plug core has six plug receiving cavities, each containing a female terminal. The center of the plug core has a pair of first interlocking terminals whose ends do not protrude beyond the female terminals. The socket housing contains a socket core and a socket shielding layer. The socket core has six socket receiving cavities that match the plug receiving cavities, each containing a male terminal. The center of the socket core has a pair of first interlocking terminals whose ends do not protrude beyond the female terminals. The signal male terminal does not protrude beyond the male terminal. When the plug is inserted into the socket, the female terminal is first inserted into the male terminal one by one, and then the first interlock terminal is inserted into the signal male terminal. A cable is connected to the tail end of both the female terminal and the male terminal. A tail cap is snapped into the tail end of both the plug housing and the socket housing. The tail cap has six branch holes. A cable passes through each branch hole. There is a straight-extending limiting wall between each pair of branch holes. The inner wall of the limiting wall fits against the cable and limits the parallel extension of the cable between each pair.

[0007] Preferably, the six plug receiving cavities are symmetrically distributed in two rows, the first interlocking terminal is located at the center of the plug core, and a notch is formed at the junction of a set of limiting walls and the side wall of the tail cap.

[0008] Preferably, a shielding ring is fitted on the cable inside the plug housing, and a baffle is built into the tail end of the plug housing. The cable passes through the baffle, and a cable sealing element is engaged between the baffle and the tail cap to seal the tail end of the plug housing.

[0009] Preferably, the socket housing is L-shaped, and the socket shielding layer includes a second shielding layer and a third shielding layer. The second shielding layer and the third shielding layer are spliced ​​together to form an L-shape that matches the socket housing, and the socket core is built into the second shielding layer and the third shielding layer.

[0010] Preferably, the male terminal is L-shaped and matches the socket housing. One end of the male terminal is inserted into the socket cavity, and the other end is connected to the power female terminal and electrically connected to the cable through the power female terminal.

[0012] Preferably, the plug housing is provided with a rotatable handle, the handle including a connecting section and symmetrically vertically distributed support sections at both ends of the connecting section. The extended end of the support section is pivotally connected to a connecting shaft provided on the side of the plug housing. The inner wall of the extended end is provided with a toothed groove circumferentially. The two sides of the socket housing are provided with racks that match the toothed grooves. The handle drives the toothed grooves and racks to engage by pivoting, so as to engage the plug housing and the socket housing into one piece. The connecting section extends straight and has a limiting slot in its middle. A locking block is movably inserted into the limiting slot. A retaining ring is fixed on the outer wall of the socket housing. When the connecting section is in contact with the outer wall of the plug housing, it pushes the locking block forward, and the front end of the locking block engages in the retaining ring to lock the handle and the plug housing.

[0018] 2. A notch is formed at the connection between the limiting wall and the side wall of the tail cap to avoid completely covering the cable, so that the cable can extend straight while having a certain amount of room for movement, making it easier for the cable to extend and effectively reducing unnecessary wear caused by shaking, ensuring the integrity of the cable, facilitating the cable to be threaded, and reducing cable wear.

[0019] 3. By setting the groove depths of the first tooth groove and the second tooth groove to be different, the engagement of the first tooth groove and the first locking tooth is limited, and the engagement of the second tooth groove and the second locking tooth is limited, so as to play a role in preventing mistakes and ensuring that the handle can be pivotally locked to the plug and socket for convenient actual use.

[0033] like Figures 1 to 10As shown, this utility model discloses a multifunctional six-core connector, including a plug and a socket that can be plugged into each other. The plug housing 101 contains a plug core 102 and a first shielding layer 103. The plug core 102 has six plug receiving cavities 104, and each receiving cavity 104 contains a female terminal 105. The center of the plug core 102 has a first interlocking terminal 106 whose outer ends do not protrude beyond the female terminal 105. The socket housing 201 contains a socket core 202 and a socket shielding layer. The socket core 202 contains six socket receiving cavities 203 that match the plug receiving cavities 104, and each socket receiving cavity 203 contains a male terminal 204. The socket core 202... The center of the plug has a pair of signal male terminals 205 that do not protrude outward from the male terminals 204. When the plug is inserted into the socket, the female terminal 105 is first inserted into the male terminals 204 one by one, and then the first interlock terminal 106 is inserted into the signal male terminal 205. The tail ends of the female terminal 105 and the male terminal 204 are each connected to a cable 3. The tail ends of the plug housing 101 and the socket housing 201 are each snapped with a tail cap 4. The tail cap 4 has six branch holes 401. Each branch hole 401 has a cable 3 inserted through it. Each pair of branch holes 401 has a straight extending limiting wall 402 between adjacent points. The inner wall of the limiting wall 402 is in contact with the cable 3 and limits the parallel extension of the cable 3 between each pair.

[0034] This solution is a six-core connector consisting of a six-core plug and a six-core socket. A tail cap 4 is provided at the end of the six-core plug and socket to limit the extension direction of the cable 3, and a limiting wall 402 is provided to support the cable 3, so as to avoid the cables 3 from getting tangled. While making the wiring reasonable, the support surface of the cable 3 is increased, thereby reducing stress and protecting the cable 3, ensuring safe use.

[0035] The lengths of the first interlock terminal 106 and the signal male terminal 205 are both shorter than those of the female terminal 105 and the male terminal 204, so that the insertion of the first interlock terminal 106 and the signal male terminal 205 occurs after the insertion of the female terminal 105 and the male terminal 204, ensuring that the power-on signal is issued only after the insertion of the female terminal 105 and the male terminal 204 is completed; the separation of the first interlock terminal 106 and the signal male terminal 205 occurs before the separation of the female terminal 105 and the male terminal 204, ensuring that the female terminal 105 and the male terminal 204 are separated after the power is turned off, preventing hot-plugging and ensuring safety in use.

[0036] Preferably, the six plug receiving cavities 104 summarized in this solution are symmetrically distributed in two rows. The first interlocking terminal 106 is located at the center of the plug core 102. A set of limiting walls 402 forms a notch 403 adjacent to the side wall of the tail cap 4. Further, the cross-section of the plug receiving cavity 104 is non-circular, preferably hexagonal, so that the corners form bevels for easy insertion; and the female terminal 105 is built into the plug receiving cavity 104 to prevent finger touching. In other feasible embodiments, the plug receiving cavity 104 can also be other feasible structures, which are not limited here. The notch 403 formed at the connection between the limiting wall 402 and the side wall of the tail cap 4 avoids completely covering the cable 3, so that the cable 3 can extend as straight as possible while having a certain amount of room for movement, which makes it easier for the cable 3 to extend, effectively reduces unnecessary wear caused by shaking, ensures the integrity of the cable 3, facilitates the insertion of the cable 3, and reduces wear on the cable 3.

[0037] The first shielding layer 103 is embedded in the plug core 102, and the outer wall of the first shielding layer 103 is in close contact with the inner wall of the plug core 102 to shield the six female terminals 105. A first sealing ring 113 is fitted on the outer wall of the plug core 102 to seal the gap after the plug and socket are connected.

[0038] A shielding ring 110 is fitted onto the cable 3 inside the plug housing 101, and a baffle 111 is built into the tail end of the plug housing 101. The cable 3 passes through the baffle 111, and a cable sealing element 112 is engaged between the baffle 111 and the tail cap 4 to seal the tail end of the plug housing 101. The shielding ring 110 protects the inner shielding ring and the outer shielding ring. The outer shielding ring is fitted over the inner shielding ring, and the inner shielding ring is fitted over the cable 3.

[0039] Preferably, the socket housing 201 in this solution is L-shaped, and the socket shielding layer includes a second shielding layer 206 and a third shielding layer 207. The second shielding layer 206 and the third shielding layer 207 are spliced ​​to form an L-shape that matches the socket housing 201, and the socket core 202 is built into the second shielding layer 206 and the third shielding layer 207.

[0040] The male terminal 204 is L-shaped and matches the socket housing 201. One end of it is inserted into the socket cavity 203, and the other end is connected to the power female terminal 208, and is electrically connected to the cable 3 through the power female terminal 208.

[0041] The signal male terminal 205 is L-shaped and matches the socket housing 201. A pair of second interlocking terminals 209 are provided in the socket inner core 202. The inner end of the signal male terminal 205 is inserted into the second interlocking terminal 209.

[0042] Furthermore, the plug housing 101 is provided with a rotatable handle 5. The handle 5 includes a connecting section 501 and support sections 502 symmetrically and vertically disposed at both ends of the connecting section 501. The extended end of the support section 502 is pivotally connected to a connecting shaft 107 disposed on the side of the plug housing 101. The inner wall of the extended end is provided with a toothed groove circumferentially. The two sides of the socket housing 201 are provided with racks that match the toothed grooves. The handle 5 drives the toothed grooves to engage with the racks by pivoting. The connector 501 extends straight and has a limiting slot 503 in its middle. A locking block 6 is movably inserted into the limiting slot 503. A retaining ring 210 is fixed on the outer wall of the socket housing 201. When the connector 501 is in contact with the outer wall of the connector 101, the locking block 6 is pushed forward and the front end of the locking block 6 is engaged in the retaining ring 210 to lock the handle 5 and the connector housing 101.

[0043] Furthermore, the toothed groove includes a first toothed groove 504 and a second toothed groove 505, and the groove depth of the first toothed groove 504 is greater than that of the second toothed groove 505. The front end of the rack has a first locking tooth 211 that matches the first toothed groove 504 and a second locking tooth 212 that matches the second locking groove 505. By setting the groove depths of the first toothed groove 504 and the second toothed groove 505 to be different, the first toothed groove 504 is limited to engaging only with the first locking tooth 211, and the second toothed groove 505 is limited to engaging only with the second locking tooth 212, thereby preventing misoperation and ensuring that the handle 5 can pivotally lock the plug and socket for convenient actual use.

[0044] like Figure 8 As shown, the limiting slot 503 has concave sliding grooves 506 on both sides, and the locking block 6 has protrusions 601 on both sides. The protrusions 601 are slidably engaged in the sliding grooves 506 to limit the locking block 6 in the limiting slot 503 and prevent the locking block 6 from coming out of the limiting slot 503.

[0045] Furthermore, the bottom of the locking block 6 has a hook 602, and the outer wall of the plug housing 101 has a protruding locking block 108. When the front end of the locking block 6 is inserted into the retaining ring 210, the hook 602 engages with the locking block 108 to keep the locking block 6 in a fixed position and keep the handle 5 locked.

[0046] The handle 5 has bayonets 507 on both sides, and the plug housing 101 is provided with a limiting block 109. When the connecting section 501 is in contact with the outer wall of the plug housing 101, the bayonets 507 engage with the limiting block 109 to further enhance the stability of the handle 5 in the locked state.

[0047] In addition, the plug housing 201 has a flange, and a sealing ring is embedded in the edge of the flange to provide a sealing effect after the flange is installed.

[0048] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0049] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
