Description

Technical Field

[0001] The present invention relates to the technical field of connector detection, and in particular to a metal connector detection device. Background Art

[0002] Metal connectors are electrical connection devices made of metal materials with key components (such as housings, contacts, and shielding layers) used to establish separable electrical connections between circuits. Their core value lies in high reliability, strong anti-interference capabilities, and environmental adaptability. They are widely used in the automotive, aerospace, industrial equipment, and other fields.

[0003] During the production process, metal connectors need to be tested for their plugging and unplugging life. The traditional testing method is to fix the connector socket and then use an electric push rod to drive the connector plug to repeatedly plug into the connector socket (both the connector socket and the connector plug are connected to external electrical signal detection equipment) until the circuit is broken. This method of plugging and unplugging with an electric push rod is inefficient, and due to production errors or installation errors, the actual connector plug has low accuracy during the plugging process into the connector socket, which can easily cause damage to the connector housing and pins, affecting the detection effect. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the traditional electric push rod plugging and unplugging method in the prior art, which is low in efficiency and, due to production errors or installation errors, the actual connector plug has low accuracy in the process of plugging into the connector socket, which can easily cause damage to the connector shell and pins, affecting the detection effect.

[0005] In order to achieve the above-mentioned object, the present invention adopts the following technical solution: a metal connector detection device, comprising a frame, a follower ring, a connector socket and a connector plug, wherein two follower rings are provided and are mirror-imaged and arranged at the front end of the frame, one of the follower rings is provided with a first mounting seat on the top, a second slide rail is fixedly mounted on the top of the first mounting seat, and the connector socket is slidably mounted on the second slide rail, and the other follower ring is provided with a second mounting seat on the bottom, and a plurality of quick-release seats are slidably mounted on the second mounting seat corresponding to the position of the connector socket, and further comprising: A plurality of floating buffer assemblies mounted on the quick-release seat are used to fix the connector plug to achieve adaptive plug-in detection; A plurality of clamping assemblies are mounted on the floating buffer assembly to fix connector plugs of different diameters.

[0006] In at least some embodiments, two eccentric wheels are rotatably mounted on the frame, and mutually meshing synchronous gears are fixedly mounted on the shafts of the two eccentric wheels. A motor for driving one of the synchronous gears to rotate is fixedly mounted on the back of the frame, and the follower ring is provided with two first slide rails integrally formed on both sides, and a first slide rod is slidably mounted on the first slide rail. Two pairs of limit slides are fixedly mounted on the front end of the frame, and the first slide rod is slidably inserted into the limit slide. A shaft sleeve is provided in the follower ring and is rotatably sleeved on the outer side of the eccentric wheel through the shaft sleeve.

[0007] In at least some embodiments, a plurality of vertical sliding grooves are provided on the second mounting seat, and a plurality of quick-release seats are slidably installed in the sliding grooves on the second mounting seat and a horizontal plate is fixedly installed on the back, and bolts for positioning are threadedly installed at both ends of the horizontal plate, and an internal quick-release socket is provided at the bottom of the quick-release seat, and a hollow cavity connected to the quick-release socket is provided inside the quick-release seat, and a clamping ring is fixedly installed at the bottom of the hollow cavity.

[0008] In at least some embodiments, the clamping ring is formed by welding a metal ring and two metal snap-fitting pieces, and the metal snap-fitting pieces have inward-clamping elasticity, and the top of the metal snap-fitting piece of the clamping ring is angled.

[0009] In at least some embodiments, the floating buffer assembly includes a buffer seat, a positioning seat and a floating seat. The bottom of the buffer seat is provided with multiple plugs and the plugs are movably inserted into the positioning seat through the plugs. The plugs are sleeved with a first spring. The bottom of the positioning seat is rectangular and four second sliding rods are fixedly installed. Two follower rods are slidably installed on the four second sliding rods. The two follower rods are arranged in a cross-staggered type and a sliding groove is provided on the follower rod. Two second springs are sleeved on the second sliding rod. The follower rod is centered by the elastic action of the second spring. A convex column is provided on the top of the floating seat and is slidably clamped in the sliding groove of the two follower rods through the convex column. A circular opening is provided on the side of the floating seat away from the positioning seat and a guide frame is fixedly installed at the bottom of the opening.

[0010] In at least some embodiments, a quick-release head is fixedly mounted on the top of the buffer seat. The quick-release head is in the shape of an inverted gyro and has two symmetrical angular openings at the tip thereof for adapting to the quick-release seat for quick release.

[0011] In at least some embodiments, the clamping assembly includes a ring gear, a rotating rod and an adjusting knob. The ring gear is fixedly mounted on the top of the floating seat and is arranged concentrically with the opening. The rotating rod is provided with multiple rods and is rotatably mounted on the floating seat in a circular array. The rotating rod is fixedly sleeved with a first gear that meshes with the inner teeth of the ring gear. The rotating rod is rotatably mounted with a clamping wheel for clamping the connector plug. The adjusting knob is rotatably mounted on the floating seat. The adjusting knob is fixedly sleeved with a second gear that meshes with the outer teeth of the ring gear. A torsion spring is fixedly mounted between the adjusting knob and the floating seat to drive the rotating rod to rotate back.

[0012] In at least some embodiments, the clamping wheel is fixedly sleeved with a plurality of horizontally placed limiting plates to limit the longitudinal movement of the connector plug and can rotate horizontally.

[0013] In at least some embodiments, a pin seat and a positioning frame are provided on the top of the connector socket, the top of the positioning frame is chamfered inwardly, and a plurality of pin holes are provided on the pin seat, and the pin holes are chamfered inwardly.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are: 1. In the present invention, the two eccentrics rotate synchronously in opposite directions. Since a shaft sleeve is added between the two follower rings and the eccentrics, the follower rings do not rotate on their own but only revolve. Under the guidance of the first slide rail and the limit slide, the two follower rings move synchronously to form a motion trajectory similar to that of a flying shear, thereby realizing efficient plugging and unplugging detection of metal connectors (the connector socket and connector plug are always in the same vertical line during the movement process).

[0015] 2. In the present invention, before the connector plug contacts the connector socket, the guide frame is guided by the chamfered corners in the positioning frame to accurately snap into the positioning frame (i.e., the connector plug is aligned with the connector socket). When the connector plug contacts the pin holes of the connector socket, the chamfered corners on the pin holes drive the connector plug to rotate, thereby accurately inserting the pins of the connector plug into the pin holes of the connector socket (the clamping wheel allows the connector plug to rotate only horizontally and not move vertically).

[0016] 3. In the present invention, the elastic effect of the first spring in the floating buffer assembly serves the purpose of over-the-top buffering during plugging and unplugging. When the connector socket and the connector plug are not accurately connected due to production errors or installation errors, under the guidance of the guide frame, the two cross-staggered follower rods can slide on the second slide rod, so that the floating seat can move horizontally in all directions, and the elastic effect of the second spring is used to play a buffering role during the plugging process, ultimately achieving flexible and adaptive plugging and unplugging, reducing the possibility of accidental damage to the metal connector during plugging and unplugging, and improving the plugging and unplugging accuracy.

[0017] 4. In the present invention, in the clamping assembly, rotating the adjusting knob drives the clamping wheel away from the center of the floating seat opening, inserting multiple connector plugs into the opening of the floating seat, loosening the adjusting knob and multiple clamping wheels clamp the connector plugs, which not only achieves the purpose of clamping and positioning connector plugs with different diameters, but also realizes the function of quick release and quick replacement of the connector plugs. For the plug-in and pull-out detection of metal connectors with different pin lengths, it is only necessary to adjust the height of the quick release seat on the second mounting seat.

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Embodiment, according to Figures 1-10 ,like Figure 1 As shown, a metal connector detection device provided by an embodiment of the present invention includes a frame 1, a follower coil 2, a connector socket 4 and a connector plug 9. The follower coil 2 is provided with two and the upper and lower mirror images are arranged at the front end of the frame 1, as shown in FIG. Figure 4 As shown, a first mounting seat 3 is provided on the top of one of the follower coils 2, a second slide rail 301 is fixedly installed on the top of the first mounting seat 3, and the connector socket 4 is slidably installed on the second slide rail 301, as shown in FIG. Figure 1 and Figure 5 As shown, a second mounting seat 5 is provided at the bottom of another follower coil 2, and a plurality of quick-release seats 6 are slidably installed on the second mounting seat 5 corresponding to the position of the connector socket 4. It also includes a plurality of floating buffer assemblies 7 installed on the quick-release seat 6 to fix the connector plug 9 to achieve adaptive plug-in detection, and a plurality of clamping assemblies 8 installed on the floating buffer assembly 7 to fix the connector plugs 9 of different diameters.

[0023] like Figure 1-Figure 4As shown, two eccentric wheels 101 are rotatably installed on the frame 1, and mutually meshing synchronous gears 102 are fixedly installed on the shafts of the two eccentric wheels 101. A motor for driving one of the synchronous gears 102 to rotate is fixedly installed on the back of the frame 1. The follower ring 2 is provided with two first slide rails 201 integrally formed on both sides. A first slide rod 202 is slidably installed on the first slide rail 201. Two pairs of limit slides 103 are fixedly installed at the front end of the frame 1. The first slide rod 202 is slidably inserted in the limit slide 103. A shaft sleeve 203 is provided in the follower ring 2 and is rotatably sleeved on the eccentric wheel through the shaft sleeve 203. On the outside of the wheel 101, the motor drives one of the eccentric wheels 101 to rotate, and the meshing action of the synchronous gear 102 is used to make the two eccentric wheels 101 rotate synchronously in opposite directions. Since a shaft sleeve 203 is added between the two follower rings 2 and the eccentric wheels 101, the follower ring 2 does not rotate on its own but only revolves. Under the guidance of the first slide rail 201 and the limit slide 103, the two follower rings 2 move synchronously to form a motion trajectory similar to a flying shear, thereby realizing efficient plugging and unplugging detection of metal connectors (the connector socket 4 and the connector plug 9 are always in the same vertical line during the movement).

[0024] like Figure 6 As shown, the second mounting seat 5 is provided with multiple vertical sliding grooves, and multiple quick-release seats 6 are slidably installed in the sliding grooves on the second mounting seat 5 and a horizontal plate is fixedly installed on the back. Bolts for positioning are threadedly installed at both ends of the horizontal plate. An internal quick-release socket is provided at the bottom of the quick-release seat 6, and a hollow cavity connected to the quick-release socket is provided inside the quick-release seat 6, and a clamping ring 601 is fixedly installed at the bottom of the hollow cavity. The height can be accurately adjusted by utilizing the sliding action of the quick-release seat 6 and the sliding grooves on the second mounting seat 5, and then the bolts are tightened to position, thereby achieving the purpose of plugging and unplugging detection of metal connectors with different pin lengths.

[0025] like Figure 6 and Figure 7 As shown, the clamping ring 601 is welded by a metal ring and two metal snap-fitting pieces, and the metal snap-fitting pieces have the elasticity to clamp inwards. The top of the metal snap-fitting piece of the clamping ring 601 is angled, and a quick-release head 704 is fixedly installed on the top of the buffer seat 701. The quick-release head 704 is in an inverted gyroscope shape, and the tip of the quick-release head 704 is symmetrically provided with two angular openings for adapting to the quick-release seat 6 for quick release. The quick-release head 704 on the buffer seat 701 is inserted into the hollow cavity of the quick-release seat 6 through the quick-release socket. During the insertion process, the angular openings of the quick-release head 704 are aligned with the metal snap-fitting piece of the clamping ring 601, and the tip of the quick-release head 704 pushes open the two metal snap-fitting pieces. Under the action of the metal elasticity, the snap-fitting pieces are stuck in the angular openings of the quick-release head 704. If unlocking is required, the quick-release function can be achieved by rotating the quick-release head 704 and using the diameter of the quick-release head 704 itself to push open the metal snap-fitting pieces and then pulling them out.

[0026] like Figure 7 and Figure 8 As shown, the floating buffer assembly 7 includes a buffer seat 701, a positioning seat 702 and a floating seat 703. The bottom of the buffer seat 701 is provided with a plurality of plug-in columns 705 and is movably inserted with the positioning seat 702 through the plug-in columns 705. A first spring 706 is sleeved on the plug-in column 705. The bottom of the positioning seat 702 is rectangular and fixedly installed with four second sliding rods 707. Two follower rods 709 are slidably installed on the four second sliding rods 707. The two follower rods 709 are arranged in a cross-staggered manner and a sliding groove is opened on the follower rod 709. Two second springs 708 are sleeved on the second sliding rod 707. The follower rod 709 is centered by the elastic action of the second spring 708. A convex column is provided on the top of the floating seat 703 and is slidably clamped in the sliding groove of the two follower rods 709 through the convex column. The floating seat 703 is away from the positioning seat A circular opening is provided on one side of the seat 702 and a guide frame 710 is fixedly installed at the bottom of the opening. During the plugging and unplugging process of the metal connector, the movable connection between the plug post 705 and the positioning seat 702 and the elastic effect of the first spring 706 are used to buffer the plugging and unplugging. At the same time, when the connector socket 4 and the connector plug 9 are not accurately connected due to production errors or installation errors, the two cross-staggered follower rods 709 can slide on the second slide rod 707 during the plugging process, so that the floating seat 703 can move horizontally in all directions, and the elastic effect of the second spring 708 is used to buffer the plugging process and to return the position during the unplugging process, finally realizing flexible and adaptive plugging and unplugging, reducing the possibility of accidental damage to the metal connector during plugging and unplugging, and improving the plugging and unplugging accuracy.

[0027] like Figure 9As shown, the clamping assembly 8 includes a ring gear 801, a rotating rod 802 and an adjusting knob 803. The ring gear 801 is fixedly mounted on the top of the floating seat 703 and is arranged concentrically with the opening. The rotating rod 802 is provided with multiple rods and is rotatably mounted on the floating seat 703 in an annular array. A first gear 804 that meshes with the inner teeth of the ring gear 801 is fixedly mounted on the rotating rod 802. A clamping wheel 805 for clamping the connector plug 9 is rotatably mounted on the rotating rod 802. The adjusting knob 803 is rotatably mounted on the floating seat 703. A second gear 806 that meshes with the outer teeth of the ring gear 801 is fixedly mounted on the adjusting knob 803. A torsion spring 807 is fixedly mounted between the adjusting knob 803 and the floating seat 703 for driving The movable rotating rod 802 rotates back to its original position, wherein rotating the adjusting knob 803 drives the second gear 806 to rotate, and the rotation of the second gear 806 drives the ring gear 801 to rotate, and the ring gear 801 drives multiple rotating rods 802 to rotate through the meshing action with the first gear 804. At this time, the clamping wheel 805 is away from the center of the opening of the floating seat 703, and the connector plug 9 is inserted into the opening of the floating seat 703. The adjusting knob 803 is loosened and the elastic action of the torsion spring 807 is used to drive the adjusting knob 803 to rotate in the opposite direction and return to its original position, and finally drives multiple clamping wheels 805 to clamp the connector plug 9, which not only achieves the purpose of clamping and positioning connector plugs 9 with different diameters, but also realizes the function of quick disassembly and replacement of the connector plug 9.

[0028] like Figure 9 and Figure 10 As shown, the clamping wheel 805 is fixedly provided with a plurality of horizontally arranged limit plates to limit the longitudinal movement of the connector plug 9 and can rotate horizontally. The top of the connector socket 4 is provided with a pin seat 401 and a positioning frame 402. The top of the positioning frame 402 is chamfered inwardly. The pin seat 401 is provided with a plurality of pin holes and the pin holes are chamfered inwardly. Before the connector plug 9 contacts the connector socket 4, the guide frame 710 contacts the positioning frame 402, and the guide frame 710 is guided to be accurately inserted into the positioning frame 402 (that is, the connector plug 9 is aligned with the connector socket 4) under the guiding action of the chamfer in the positioning frame 402. Since the clamping wheel 805 is provided with a plurality of horizontally arranged limit plates, when the connector plug 9 contacts the pin holes of the connector socket 4, the connector plug 9 will be driven to rotate under the guiding action of the chamfer on the pin holes, thereby accurately inserting the pins of the connector plug 9 into the pin holes of the connector socket 4.

[0029] The specific working principle is as follows: multiple connector sockets are slidably installed in the second slide rail 301 on the first mounting seat 3, and then positioned and installed with bolts, and the adjustment knob 4 is turned to drive the second gear 806 to rotate, and the rotation of the second gear 806 drives the ring gear 801 to rotate, and the ring gear 801 drives the multiple rotating rods 802 to rotate through the meshing action with the first gear 804. At this time, the clamping wheel 805 is away from the center of the opening of the floating seat 703, and the multiple connector plugs 9 are inserted into the opening of the floating seat 703 (so that the insulating part of the connector is flush with the bottom of the floating seat 703), and the adjustment knob 803 is loosened and the elastic action of the torsion spring 807 is used to drive the adjustment knob 803 to rotate back to its original position in the opposite direction, and finally drive the multiple clamping wheels 805 to clamp the connector plugs 9, which not only achieves the purpose of clamping and positioning connector plugs 9 with different diameters, but also realizes the function of quick disassembly and quick replacement of the connector plugs 9, and at the same time, the connector plugs 9 and the connector socket 4 are contacted with the external electrical signal detection equipment; After the installation is completed, the pneumatic device and the motor drive one of the eccentric wheels 101 to rotate, and the meshing action of the synchronous gear 102 is used to make the two eccentric wheels 101 rotate synchronously in opposite directions. Since the shaft sleeve 203 is added between the two follower rings 2 and the eccentric wheels 101, the follower rings 2 will not rotate on their own but will only revolve. Under the guidance of the first slide rail 201 and the limit slide 103, the two follower rings 2 move synchronously to form a motion trajectory similar to that of a flying shear, thereby realizing efficient plugging and unplugging detection of metal connectors (the connector socket 4 and the connector plug 9 are always in the same vertical line during the movement process), and counting is performed by an external electrical signal detection device until a circuit is broken. When the floating buffer assembly 7 needs to be replaced, the quick-release head 704 on the buffer seat 701 is inserted into the hollow cavity of the quick-release seat 6 through the quick-release jack. During the insertion process, the angular opening of the quick-release head 704 is aligned with the metal snap-fitting piece of the clamping ring 601, and the tip of the quick-release head 704 pushes open the two metal snap-fitting pieces. Under the action of the metal elasticity, the snap-fitting pieces are stuck in the angular opening of the quick-release head 704. If unlocking is required, just rotate the quick-release head 704 and use the diameter of the quick-release head 704 itself to push open the metal snap-fitting piece and then pull it out to achieve the quick installation and quick release function.

[0030] During the plug-in and pull-out testing of metal connectors with different pin lengths, the height can be precisely adjusted by sliding the quick-release seat 6 and the slide groove on the second mounting seat 5, and then the bolts are tightened to position the connectors. During the plug-in and pull-out detection process, before the connector plug 9 contacts the connector socket 4, the guide frame 710 contacts the positioning frame 402, and the guide frame 710 is accurately inserted into the positioning frame 402 under the guiding action of the chamfer inside the positioning frame 402 (that is, the connector plug 9 is aligned with the connector socket 4). Since a plurality of horizontally placed limit plates are provided on the clamping wheel 805, when the connector plug 9 contacts the pin holes of the connector socket 4, the connector plug 9 is driven to rotate under the guiding action of the chamfer on the pin holes, thereby accurately inserting the pins of the connector plug 9 into the pin holes of the connector socket 4. Specifically, the pins of the connector plug 9 are inserted into the pin holes of the connector socket 4 by using the plug post 705 and the positioning seat 706. The movable plug-in of 02 and the elastic effect of the first spring 706 serve the purpose of over-the-top buffering during plugging and unplugging. At the same time, when the connector socket 4 and the connector plug 9 are not accurately connected due to production errors or installation errors, under the guidance of the guide frame 710, the two cross-staggered follower rods 709 can slide on the second slide rod 707, so that the floating seat 703 can move horizontally in all directions, and the elastic effect of the second spring 708 plays a buffering role during the plug-in process and plays a returning role during the unplugging process, finally realizing flexible adaptive plug-in and unplugging, reducing the possibility of accidental damage to the metal connector during plug-in and unplugging, and improving the plug-in and unplugging accuracy.
