Description

Technical Field

[0001] This invention relates to the field of electromechanical components, and in particular to a connector with a cover that has an anti-loosening function. Background Technology

[0002] Connectors are common electromechanical components. They are attached to the end of a wire and can be connected to another connector that is paired with another wire.

[0003] Existing connectors with covers also include a base and a sleeve. The sleeve is connected to the base, and the cover is hinged to the base. In the past, the cover was threaded onto the sleeve, or inserted into the sleeve, or snapped onto the sleeve. When using the connector, the cover may become loose, resulting in poor protective effect and inconvenience. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a connector with an anti-loosening function for the cover, which can prevent the cover from becoming loose, ensure the protective effect of the cover, and facilitate use.

[0005] According to a first aspect of the present invention, a connector with an anti-loosening function for the cover body includes a base; a connecting rod, one end of which is hinged to the base, the hinge axis of the connecting rod extending in a left-right direction; a rotating rod, the rotating rod being rotatably connected to the other end of the connecting rod, the rotation axis of the rotating rod extending along the axis of the rotating rod, and the rotating rod being slidable along the axial direction of the rotating rod; a drive spring, sleeved on the rotating rod, one end of the drive spring being connected to the rotating rod, the other end of the drive spring being connected to the connecting rod, the drive spring being used to drive the rotating rod to move upward; a sleeve, the lower end of which is connected to the base, the outer peripheral wall of the sleeve being provided with a plurality of helical grooves, the upper ends of the helical grooves extending out of the sleeve; a cover body, one end of which is connected to one end of the rotating rod, the other end of the cover body being used to fit onto the sleeve from the upper end of the sleeve, the inner peripheral wall of the cover body being provided with guide posts, the guide posts corresponding one-to-one with the helical grooves, the guide posts being insertable into the helical grooves and sliding along the helical grooves.

[0006] According to an embodiment of the present invention, a connector with an anti-loosening function for the cover has at least the following beneficial effects: Since the rotating rod is rotatably connected to the connecting rod, and the cover is connected to one end of the rotating rod, the cover can slide with the rotating rod. The driving spring is used to drive the cover to slide with the rotating rod and move away from the sleeve. The cover and the sleeve are connected by the spiral groove and the guide post. When the guide post on the cover slides to the lower end of the spiral groove, the driving spring is compressed, and the driving spring applies a pulling force to the rotating rod, causing the rotating rod and the cover to maintain a tendency to move away from the sleeve. This makes the guide post press against the inner wall of the spiral groove, thereby restricting the cover and preventing it from loosening, thus facilitating its use.

[0007] According to some embodiments of the present invention, a rotating shaft is also included. The base is provided with two connecting blocks, which are spaced apart in the left-right direction. The rotating shaft passes through the two connecting blocks in the left-right direction and extends in the left-right direction. One end of the connecting rod is rotatably connected to the rotating shaft and is disposed between the two connecting blocks. The one end of the connecting rod can slide in the left-right direction on the rotating shaft. Because the connecting rod is slidably connected to the rotating shaft, and the cover is connected to the connecting rod, when the connecting rod slides along the rotating shaft in the left-right direction, the cover will also translate in the left-right direction. When the center of the sleeve deviates from the predetermined position in the left-right direction, the user can manually adjust the cover so that the cover can be aligned with the center position of the sleeve, and the cover can be properly fastened to the sleeve, thus providing protection.

[0008] According to some embodiments of the present invention, the outer peripheral wall of the rotating shaft is fitted with a first retaining ring and a second retaining ring. The two connecting blocks are located on two opposite side walls in the left-right direction, one of which abuts against the first retaining ring and the other abuts against the second retaining ring. The first retaining ring and the second retaining ring can restrict the rotating shaft from sliding in the left-right direction, that is, the first retaining ring and the second retaining ring cooperate to fix the position of the rotating shaft.

[0009] According to some embodiments of the present invention, a first slot and a second slot are provided on the outer peripheral wall of the rotating shaft. The first retaining ring is engaged in the first slot and the second retaining ring is engaged in the second slot. The first slot and the second slot can make the corresponding first retaining ring and second retaining ring more tightly engaged, so as to prevent the first retaining ring and the second retaining ring from disengaging from the rotating shaft.

[0010] According to some embodiments of the present invention, both the first retaining ring and the second retaining ring are provided with a snap-fit, the snap-fit ​​being used to guide the first retaining ring or the second retaining ring into the rotating shaft. The snap-fit ​​is provided so that the first retaining ring or the second retaining ring can be quickly disassembled and assembled, thereby improving assembly efficiency.

[0011] According to some embodiments of the present invention, an elastic element is also included, one end of which is connected to the rotating shaft and the other end of which is connected to the connecting rod. The elastic element is used to drive the connecting rod to rotate around the rotating shaft. The elastic element can drive the connecting rod to rotate and automatically press against the sleeve.

[0012] According to some embodiments of the present invention, the outer peripheral wall of the sleeve is provided with a plurality of spiral grooves, the upper end of the spiral grooves extending out of the sleeve, and the inner peripheral wall of the cover is provided with guide posts, the guide posts corresponding one-to-one with the spiral grooves, the guide posts being able to be inserted into the spiral grooves and slide along the spiral grooves, the spiral grooves being provided to facilitate the guidance of the guide posts into the sleeves, thereby guiding the cover to be fitted onto the sleeves, and the cover being difficult to detach vertically from the sleeves.

[0013] According to some embodiments of the present invention, the base has a receiving groove, the bottom of the receiving groove has an insertion hole, the insertion hole extends vertically, a baffle is provided on the outer peripheral wall of the sleeve, the lower end of the sleeve is inserted into the insertion hole, the baffle is engaged in the receiving groove, the receiving groove makes the sleeve and the base more tightly connected, and the baffle prevents the sleeve from detaching from the insertion hole.

[0014] According to some embodiments of the present invention, a gasket is further included, the upper end of which abuts against the lower end of the baffle, and the lower end of which abuts against the bottom of the receiving groove. The gasket is provided to prevent the baffle and the bottom of the receiving groove from rigidly contacting each other, thereby causing deformation of the sleeve.

[0015] According to some embodiments of the present invention, the baffle is detachably connected to the base by screws, which facilitates the installation and removal of the sleeve.

[0016] According to some embodiments of the present invention, the base is provided with two external countersunk holes, which are arranged in a left-right direction. The external countersunk holes facilitate the use of countersunk screws to fix the base and additional connecting blocks.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] Reference Figures 1 to 5A connector with an anti-loosening function for its cover includes a base 100; a connecting rod 300, one end of which is hinged to the base 100, and the hinge axis of the connecting rod 300 extends in a left-right direction; a rotating rod 700, which is rotatably connected to the other end of the connecting rod 300, and the rotation axis of the rotating rod 700 extends along the axis of the rotating rod 700, and the rotating rod 700 can slide along the axial direction of the rotating rod 700; and a drive spring 800, which is sleeved on the rotating rod 700, one end of the drive spring 800 is connected to the rotating rod 700, and the other end is connected to the connecting rod 300, and the drive spring 800 is used for... The drive rod 700 moves upward; the sleeve 500 is connected to the base 100 at its lower end, and the outer peripheral wall of the sleeve 500 is provided with multiple spiral grooves 510, the upper end of the spiral grooves 510 extending out of the sleeve 500; the cover 600 is connected to one end of the drive rod 700 at one end, and the other end of the cover 600 is used to fit the sleeve 500 from the upper end of the sleeve 500, and the inner peripheral wall of the cover 600 is provided with guide posts 610, the guide posts 610 correspond one-to-one with the spiral grooves 510, and the guide posts 610 can be inserted into the spiral grooves 510 and slide along the spiral grooves 510. The rotating rod 700 is rotatably connected to the connecting rod 300, and the cover 600 is connected to one end of the rotating rod 700. Therefore, the cover 600 can slide with the rotating rod 700. The driving spring 800 is used to drive the cover 600 to slide with the rotating rod 700 and move away from the sleeve 500. The cover 600 and the sleeve 500 are connected by a helical groove 510 and a guide post 610. When the guide post 610 on the cover 600 slides to the lower end of the helical groove 510, the driving spring 800 is compressed, and the driving spring 800 provides tension to the rotating rod 700. This causes the rotating rod 700 and the cover 600 to maintain a tendency to move away from the sleeve 500, so that the guide post 610 abuts against the inner wall of the spiral groove 510, thereby restricting the cover 600 and preventing it from loosening, making it convenient to use. It is understood that the width of the connecting rod 300 in the left-right direction is less than the left-right interval between the two connecting blocks 110; the drive spring 800 can be a compression spring, which is used in this embodiment; the drive spring 800 can also be a tension spring. When the drive spring 800 is a tension spring, one end of the tension spring is connected to the connecting rod 300, and the other end is connected to the cover 600, as shown in the reference. Figure 2 When the cover 600 is fastened, the extension direction of the rotating rod 700 is along the vertical direction, and the tension spring can be set between the cover 600 and the connecting rod 300; similarly, when the drive spring 800 is a compression spring, the upper end of the compression spring is connected to the upper end of the rotating rod 700, and the lower end of the compression spring is connected to the connecting rod 300, that is, the compression spring is set between the upper end of the connecting rod 300 and the upper end of the rotating rod 700.

[0036] In some embodiments, a rotating shaft 200 is also included. The base 100 is provided with two connecting blocks 110, which are spaced apart in the left-right direction. The rotating shaft 200 passes through the two connecting blocks 110 in the left-right direction and extends in the left-right direction. One end of a connecting rod 300 is rotatably connected to the rotating shaft 200, and the other end of the connecting rod 300 is disposed between the two connecting blocks 110. The other end of the connecting rod 300 can slide in the left-right direction on the rotating shaft 200. Because the connecting rod 300 is slidably connected to the rotating shaft 200, and the cover 600 is connected to the connecting rod 300, when the connecting rod 300 slides along the rotating shaft 200 in the left-right direction, the cover 600 will also translate in the left-right direction. When the center of the sleeve 500 deviates from the predetermined position in the left-right direction, the user can manually adjust the cover 600 so that the cover 600 is aligned with the sleeve 500. At the center, the cover 600 can be properly fastened onto the sleeve 500, providing protection. It should be noted that the outer contour of the cover 600 is cylindrical, and the axis of the cover 600 is the axis of the cylinder. Correspondingly, the sleeve 500 is also cylindrical. The fact that the axis of rotation of the cover 600 is the same as its axis means that the cover 600 can rotate. This means that the middle position of the shaft end of the cover 600 is rotatably connected to the other end of the connecting rod 300. One end of the cover 600 refers to its closed end, and the middle position refers to the center of the closed end, as the cover 600 is cylindrical; the other end of the cover 600 refers to its open end, the end through which the cover 600 is fitted onto the sleeve 500.

[0037] In some embodiments, refer to Figure 4 and Figure 5 The outer peripheral wall of the rotating shaft 200 is fitted with a first retaining ring 210 and a second retaining ring 220. Two connecting blocks 110 are located on two opposite side walls in the left-right direction, one abutting against the first retaining ring 210 and the other against the second retaining ring 220. The first retaining ring 210 and the second retaining ring 220 can restrict the rotating shaft 200 from sliding in the left-right direction, that is, the first retaining ring 210 and the second retaining ring 220 cooperate to fix the position of the rotating shaft 200. It can be understood that since the two connecting blocks 110 are arranged in the left-right direction, and the connecting block 110 is a three-dimensional object, the connecting block 110 must have thickness in the left-right direction. The two opposite side walls of the two connecting blocks 110 in the left-right direction refer to the two sides of the two connecting blocks 110 facing each other in the left-right direction. It should be noted that the two side walls of the two connecting blocks 110 that are separated in the left-right direction and the two side walls of the two connecting blocks 110 that are opposite in the left-right direction are equivalent replacements.

[0038] In some embodiments, the outer peripheral wall of the rotating shaft 200 is also fitted with a third retaining ring and a fourth retaining ring. Two connecting blocks 110 are located on two side walls that are separated in the left and right directions. One of them abuts against the third retaining ring and the other abuts against the fourth retaining ring. The first retaining ring 210, the second retaining ring 220, the third retaining ring and the fourth retaining ring are all retaining rings of the same type and are all provided with a bayonet 250.

[0039] In some embodiments, a first slot 230 and a second slot 240 are provided on the outer peripheral wall of the rotating shaft 200. A first retaining ring 210 is engaged in the first slot 230 and a second retaining ring 220 is engaged in the second slot 240. The first slot 230 and the second slot 240 can make the corresponding first retaining ring 210 and second retaining ring 220 more tightly engaged, preventing the first retaining ring 210 and the second retaining ring 220 from disengaging from the rotating shaft 200.

[0040] In some embodiments, both the first retaining ring 210 and the second retaining ring 220 are provided with a snap-fit ​​250. The snap-fit ​​250 is used to guide the first retaining ring 210 or the second retaining ring 220 into the rotating shaft 200. The snap-fit ​​250 enables the first retaining ring 210 or the second retaining ring 220 to be quickly disassembled and assembled, thereby improving assembly efficiency.

[0041] In some embodiments, an elastic element 400 is further included. One end of the elastic element 400 is connected to the rotating shaft 200, and the other end is connected to the connecting rod 300. The elastic element 400 is used to drive the connecting rod 300 to rotate around the rotating shaft 200. The elastic element 400 can drive the connecting rod 300 to rotate and automatically snap onto the sleeve 500. It is understood that the elastic element 400 is a torsion spring, a coil spring, or a spring sheet. It should be noted that one end of the elastic element 400 is connected to the rotating shaft 200, and the other end abuts against the rear end of the connecting rod 300. The elastic element 400 drives the connecting rod 300 to rotate forward, that is, drives the cover 600 to snap onto the sleeve 500. It is understood that the rotating shaft 200 can be fixedly installed on the connecting block 110 or can rotate relative to the connecting block 110. When the rotating shaft 200 and the connecting block 110 rotate relative to each other, the effect of the elastic element 400 will be reduced, but it will not hinder the opening and closing of the cover 600.

[0042] In some embodiments, the inner peripheral wall of the cover 600 is connected to a cushioning pad.

[0043] In some embodiments, the outer peripheral wall of the sleeve 500 is provided with multiple spiral grooves 510, the upper end of the spiral grooves 510 extends out of the sleeve 500, and the inner peripheral wall of the cover 600 is provided with guide posts 610, the guide posts 610 correspond one-to-one with the spiral grooves 510, the guide posts 610 can be inserted into the spiral grooves 510 and slide along the spiral grooves 510, the spiral grooves 510 are provided to facilitate the guide posts 610 to enter, thereby guiding the cover 600 to be sleeved on the sleeve 500, and the cover 600 is difficult to detach from the sleeve 500 vertically.

[0044] In some embodiments, the base 100 has a receiving groove 120, and the bottom of the receiving groove 120 has an insertion hole 130. The insertion hole 130 extends vertically, and a baffle 520 is provided on the outer peripheral wall of the sleeve 500. The lower end of the sleeve 500 is inserted into the insertion hole 130, and the baffle 520 is engaged in the receiving groove 120. The receiving groove 120 makes the connection between the sleeve 500 and the base 100 tighter, and the baffle 520 prevents the sleeve 500 from detaching from the insertion hole 130. It can be understood that the horizontal cross-sectional area of ​​the receiving groove 120 is larger than the horizontal cross-sectional area of ​​the insertion hole 130, and the horizontal cross-sectional area of ​​the baffle 520 is located between the horizontal cross-sectional area of ​​the receiving groove 120 and the horizontal cross-sectional area of ​​the insertion hole 130.

[0045] In some embodiments, a gasket 140 is also included. The upper end of the gasket 140 abuts against the lower end of the baffle 520, and the lower end of the gasket 140 abuts against the bottom of the receiving groove 120. The gasket 140 is provided to prevent the baffle 520 and the bottom of the receiving groove 120 from rigidly contacting each other, which would cause the sleeve 500 to deform. It is understood that the gasket 140 can be a rubber gasket, a plastic gasket, or a felt gasket.

[0046] In some embodiments, the baffle 520 is detachably connected to the base 100 by screws 530, facilitating the installation and removal of the sleeve 500.

[0047] In some embodiments, the base 100 is provided with two external countersunk holes 150, which are arranged in the left-right direction.
