Utility Model Content
[0004] To address the drawback of existing housing assemblies where the plug housing part easily detaches from the socket housing part under external force, this utility model proposes a housing assembly in which the plug housing part and the socket housing part are more securely connected.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An anti-accidental contact cable connection housing assembly includes a socket housing portion and a plug housing portion;
[0007] The socket housing includes a mounting base and a locking block, with the locking block fixedly connected to the outer side of the end of the mounting base;
[0008] The plug housing includes a base, a connecting sleeve, a connecting plate, and a limiting plate. The connecting sleeve can be fitted onto the end of the fixed base. One side of the connecting sleeve is raised, forming a clearance groove on the inner side for avoiding the locking block. The connecting sleeve is fixedly connected to the end of the base. The middle part of the connecting plate is hinged to the outer side of the base. One end of the connecting plate extends into the clearance groove and is provided with a first locking head. The limiting plate is slidably connected to the outer side of the base. The housing assembly includes a connected state and an unlocked state. In the connected state, the connecting sleeve is fitted onto the fixed base, the connecting plate hooks the locking block through the first locking head, and the limiting plate abuts against the inner side of the connecting plate. In the unlocked state, the limiting plate is disengaged from the inner side of the connecting plate.
[0009] With the above settings, when the plug housing part and the socket housing part are plugged in, the housing assembly is in the connected state. The connecting plate hooks the locking block through the first locking head to prevent the plug housing part from being pulled out. The limiting plate abuts against the connecting plate to prevent the connecting plate from rotating, thereby achieving the locking function and further preventing accidental contact with the plug housing part and disengagement from the socket housing part. After sliding the limiting plate, the housing assembly can be switched to the unlocked state, making it convenient to pull out the plug housing part.
[0010] Furthermore, the plug housing also includes a mounting bracket, which is detachably mounted on the outside of the base. The middle part of the connecting plate is hinged to the side of the mounting bracket away from the base. A limiting plate is disposed between the connecting plate and the mounting bracket and is slidably connected to the mounting bracket.
[0011] With the above setup, the limiting plate and the connecting plate are mounted on the base via a mounting bracket.
[0012] Furthermore, the outer side of the base is provided with a sliding groove extending in the front-to-back direction. The mounting bracket includes a first base plate and a first rib. The edge of the first base plate is slidably connected in the sliding groove. The end of the first base plate away from the socket housing is provided with two first notches extending in the front-to-back direction.

[0013] The above configuration facilitates the installation of the mounting bracket on the base; the connecting plate is hinged to the mounting bracket via the first rib.
[0014] Furthermore, the limiting plate includes a second base plate and a support platform. The inner side of the first protruding rib is provided with a first limiting groove and a second limiting groove. The end of the second base plate near the socket housing is provided with two second notches. The second base plate forms a second elastic plate on the outer side of the second notches. A third locking head is provided on the second elastic plate. The support platform is fixedly connected to the second base plate. In the connected state, the third locking head is embedded in the first limiting groove, and the support platform abuts against the inner side of the connecting plate. In the unlocked state, the third locking head is embedded in the second limiting groove.
[0015] With the above settings, the limiting plate is easier to position. After the third locking head of the limiting plate is inserted into the first or second limiting groove, the limiting plate will not move back and forth.
[0016] Furthermore, the limiting plate also includes a lever plate and a second rib. The second rib is slidably connected in the first notch and fixedly connected to the second base plate. The lever plate is fixedly connected to one end of the second base plate away from the socket housing.
[0017] With the above settings, the push plate can easily push the limiting plate, and the second rib is located in the first notch, which plays a guiding role and improves the sliding stability of the limiting plate.
[0018] Furthermore, the socket housing also includes a sealing ring, which is installed at the end of the base. In the connected state, the end face of the base abuts against the sealing ring.
[0019] The above settings improve the sealing between the base and the fixed seat, preventing external moisture from affecting electrical safety during electrical connection.
[0020] Furthermore, the socket housing also includes a third protruding rib fixedly connected to the outside of the fixing base. There are two third protruding ribs located on the left and right sides of the first clip head. In the connected state, the left and right sides of the clearance groove abut against the third protruding rib.

[0031] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0032] like Figures 1 to 9An anti-accidental contact cable connection housing assembly includes a socket housing portion and a plug housing portion; the socket housing portion includes a fixing base 3 and a locking block 4, the locking block 4 being fixedly connected to the outer side of the end of the fixing base 3;
[0033] The plug housing includes a base 5, a connecting sleeve 6, a connecting plate 7, and a limiting plate 8. The connecting sleeve 6 can be fitted onto the end of the fixed base 3. One side of the connecting sleeve 6 is raised, and a clearance groove 9 is formed on the inner side to avoid the locking block 4. The connecting sleeve 6 is fixedly connected to the end of the base 5. The middle part of the connecting plate 7 is hinged to the outside of the base 5. One end of the connecting plate 7 extends into the clearance groove 9 and is provided with a first locking head 10. The limiting plate 8 is slidably connected to the outside of the base 5.
[0034] The housing assembly includes a connected state and an unlocked state. In the connected state, the connecting sleeve 6 is fitted onto the fixed base 3, the connecting plate 7 hooks onto the locking block 4 through the first locking head 10, and the limiting plate 8 abuts against the inner side of the connecting plate 7. In the unlocked state, the limiting plate 8 is disengaged from the inner side of the connecting plate 7.
[0035] With the above settings, when the plug housing part and the socket housing part are plugged in, the housing assembly is in the connected state. The connecting plate 7 hooks the locking block 4 through the first locking head 10 to prevent the plug housing part from being pulled out. The limiting plate 8 abuts against the connecting plate 7 to prevent the connecting plate 7 from rotating, thereby achieving the locking function and further preventing accidental contact with the plug housing part and disengagement from the socket housing part. After sliding the limiting plate 8, the housing assembly can be switched to the unlocked state, making it convenient to pull out the plug housing part.
[0036] Specifically, the mounting base 3 has a tubular structure, which facilitates the installation of conductive hardware inside for electrical connection with cables. One end of the mounting base 3 is used to install on the power device, and the aforementioned locking block 4 is fixedly connected to the upper side of the other end of the mounting base 3; the connecting sleeve 6 is integrally formed on the front end of the base 5. Figure 1 The markings indicate the front, back, left, and right directions of the housing assembly. Specifically, the direction in which the plug housing is inserted into the socket housing is the front, and the direction in which the plug housing is pulled out is the rear. One end of the cable is connected to power, and the other end extends through the base 5 into the connecting sleeve 6. Initially, the housing assembly is in the unlocked state, as shown below. Figure 8 and Figure 9 The limiting plate 8 does not abut against the side of the connecting plate 7 near the base 5. The rear end of the connecting plate 7 rotates towards the base 5, and the front end of the connecting plate 7 tilts upward. The inner diameter of the connecting sleeve 6 matches the outer diameter of the fixed base 3. The connecting sleeve 6 is fitted onto the fixed base 3. The first locking head 10 at the front end of the connecting plate 7 passes over the upper side of the locking block 4, and the locking block 4 is located in the clearance groove 9. Then, the rear end of the connecting plate 7 is rotated upward, and the front end of the connecting plate 7 moves downward. The front end of the connecting plate 7 hooks onto the locking block 4 through the first locking head 10. The limiting plate 8 slides forward, and the limiting plate 8 abuts against the side of the rear end of the connecting plate 7 near the base 5. Figure 6 and Figure 7When the plug housing is accidentally touched, the rear end of the connecting plate 7 will not rotate toward the base 5, that is, the first latch 10 at the front end of the connecting plate 7 will not disengage from the latch 4. At this time, the cable is electrically connected to the hardware in the fixing seat 3 so that external power can be introduced into the power device through the cable and hardware. The housing assembly is in the connected state, and the plug housing part will not be pulled out from the socket housing part. When it is necessary to pull out the housing assembly, push the limiting plate 8 backward. After the limiting plate 8 disengages from the rear end of the connecting plate 7, the rear end of the connecting plate 7 can rotate downward again. After the front end of the connecting plate 7 disengages from the latch 4, the plug housing part can be pulled out.
[0037] As one implementation, the plug housing also includes a mounting bracket, which is detachably mounted on the outside of the base 5. The middle part of the connecting plate 7 is hinged to the side of the mounting bracket away from the base 5. The limiting plate 8 is disposed between the connecting plate 7 and the mounting bracket and is slidably connected to the mounting bracket.
[0038] With the above settings, the limiting plate 8 and the connecting plate 7 are mounted on the base 5 via the mounting bracket.
[0039] Specifically, the middle part of the connecting plate 7 is hinged to the base 5 via the mounting bracket. The connecting plate 7 is located on the side of the mounting bracket away from the base 5. The connecting plate 7 extends forward and backward, and the limiting plate 8 can slide back and forth on the mounting bracket.
[0040] As one implementation, a sliding groove 12 extending in the front-to-back direction is provided on the outer side of the base 5. The mounting bracket includes a first base plate 11 and a first rib 13. The edge of the first base plate 11 is slidably connected in the sliding groove 12. Two first notches 14 extending in the front-to-back direction are provided at the end of the first base plate 11 away from the socket housing. A first elastic plate 15 is formed between the two first notches 14. A second locking head 16 is provided on the first elastic plate 15. A locking hole 17 is provided on the base 5. The second locking head 16 is inserted into the locking hole 17. The two first ribs 13 are fixedly connected to the side of the first base plate 11 away from the base 5. The middle part of the connecting plate 7 is hinged between the two first ribs 13. The limiting plate 8 is slidably connected to the first base plate 11.
[0041] The above configuration facilitates the installation of the mounting bracket on the base 5; the connecting plate 7 is hinged to the mounting bracket via the first protruding rib 13.
[0042] The base 5 of this application has fixed blocks fixedly connected to the left and right sides of the mounting frame. A sliding groove 12 is located inside the fixed blocks. The first base plate 11 is positioned between the fixed blocks, with its edge embedded in the sliding groove 12, allowing the mounting frame to slide stably back and forth. A first rib 13 is integrally formed on the side of the first base plate 11 away from the base 5. The first rib 13 extends in the front-back direction, supporting the left and right sides of the connecting plate 7. The middle parts of the left and right sides of the connecting plate 7 are hinged to the corresponding first ribs 13. A limiting plate 8 is slidably connected to the side of the first base plate 11 away from the base 5. Two front-back extending first notches 14 are machined at the end of the first base plate 11 away from the socket housing. A shape is formed between the two first notches 14. The first elastic plate 15 and the first base plate 11 are made of plastic, metal or other materials and have good elasticity. The second locking head 16 is located on the lower rear end of the first elastic plate 15. When the mounting bracket is installed, the first base plate 11 slides forward along the upper side of the base 5, the second locking head 16 abuts against the upper side of the base 5, the rear end of the first elastic plate 15 elastically deforms upward, and after the front end of the first base plate 11 slides into the slide groove 12, the mounting bracket continues to slide forward. When the second locking head 16 slides to the locking hole 17, the first elastic plate 15 rebounds, the second locking head 16 locks into the locking hole 17, and the mounting bracket is locked to prevent the mounting bracket from moving back and forth. The mounting bracket installation is completed.
[0043] As one implementation, the limiting plate 8 includes a second base plate 19 and a support platform 20. The inner side of the first protruding rib 13 is provided with a first limiting groove 21 and a second limiting groove 22. The end of the second base plate 19 near the socket housing is provided with two second notches 23. The second base plate 19 forms a second elastic plate 24 on the outside of the second notches 23. A third locking head 25 is provided on the second elastic plate 24. The support platform 20 is fixedly connected to the second base plate 19. In the connected state, the third locking head 25 is embedded in the first limiting groove 21, and the support platform 20 abuts against the inner side of the connecting plate 7. In the unlocked state, the third locking head 25 is embedded in the second limiting groove 22.
[0044] With the above settings, the limiting plate 8 is easier to position. After the third locking head 25 of the limiting plate 8 is embedded in the first limiting groove 21 or the second limiting groove 22, the limiting plate 8 will not move back and forth.
[0045] The second base plate 19 of this application has two second notches 23 machined on the left and right sides of its front end, so that two second elastic plates 24 are naturally formed on the left and right sides of the front end of the second base plate 19. The second notches 23 allow the second elastic plates 24 to elastically deform inward. When assembling the plug housing, the mounting bracket is assembled first, and then the limiting plate 8 is assembled. Figure 4The third locking head 25 of the limiting plate 8 extends forward and is inserted between the two first protruding ribs 13. The third locking head 25 slides forward along the inner side of the first protruding ribs 13, and the front end of the second elastic plate 24 deforms inward. When the third locking head 25 slides to the second limiting groove 22, the second elastic plate 24 rebounds, and the third locking head 25 is engaged in the second limiting groove 22. Figure 9 The third locking head 25 is basically semi-circular. When the limiting plate 8 is pushed forward or backward, the third locking head 25 can slide out from the second limiting groove 22. For example, sliding the limiting plate 8 backward can pull out the limiting plate 8, and sliding the limiting plate 8 forward will cause the third locking head 25 to slide to the first limiting groove 21 and lock into the first limiting groove 21.
[0046] As one implementation, the limiting plate 8 also includes a toggle plate 26 and a second rib 27. The second rib 27 is slidably connected in the first notch 14 and fixedly connected to the second base plate 19. The toggle plate 26 is fixedly connected to one end of the second base plate 19 away from the socket housing.
[0047] With the above settings, the push plate 26 can easily push the limiting plate 8, and the second rib 27 is located in the first notch 14, which plays a guiding role and improves the sliding stability of the limiting plate 8.
[0048] As one implementation, the socket housing also includes a sealing ring 28, which is installed at the end of the fixing base 3. In the connected state, the end face of the base 5 abuts against the sealing ring 28.
[0049] The above settings improve the sealing between the base 5 and the fixed base 3, preventing external moisture from affecting electrical safety during electrical connection.
[0050] As one implementation, the socket housing also includes a third protruding rib 29 fixedly connected to the outside of the fixing seat. There are two third protruding ribs located on the left and right sides of the first latch. In the connected state, the left and right sides of the clearance groove abut against the third protruding rib.
[0051] With the above configuration, the third rib supports the connecting sleeve through the clearance groove, thereby improving the stability of the connecting sleeve.
[0052] The third rib of this application extends in the front-to-back direction, and the rear end of the third rib is chamfered to facilitate entry into the clearance groove.
