Description

Technical Field

[0001] This utility model belongs to the field of testing equipment, and in particular relates to a quick-connect structure for electrical testing of analog and digital signals. Background Technology

[0002] Currently, when testing the charging port cover of a car, the charging port cover is first placed on the test platform, and then the connector of the charging port cover is inserted into the socket on the test platform to realize the electrical connection and signal exchange between the charging port cover and the socket, which facilitates subsequent testing.

[0003] During testing, equipment manufacturers typically install a dedicated socket on the test platform that matches the charging port cover connector. This connector uses a multi-unit male-type snap-fit ​​structure, while the matching socket has a corresponding female-type snap-fit ​​assembly; the two are mechanically connected via these snaps. Because automotive products have stringent stability requirements, this snap-fit ​​system creates a high-strength engagement after interlocking, making post-test separation operations significantly challenging—requiring specialized tools and drastically increasing disassembly time. In actual testing, the connection strength between the charging port cover connector and the matching socket is not high; this high-strength engagement reduces testing efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is: the connection strength between the charging port cover connector and the matching socket in the existing actual testing process is not high, and the high-strength meshing state of the existing charging port cover connector and the matching socket causes the problem of reduced testing efficiency. This utility model provides a quick-connection structure for analog and digital signal electrical testing.

[0005] To address the aforementioned issues, this utility model provides a quick-connect structure for analog and digital signal electrical testing, comprising a male connector and a female socket for mating, wherein the female socket includes a base, female terminals, and a lever-type locking mechanism.

[0006] The base has a cavity extending along a first direction. The cavity includes a first cavity and a second cavity. The first cavity is used for inserting the male connector, and the female terminal is fixed in the second cavity.

[0007] The seat is provided with a clearance groove, which extends along a first direction and communicates with the first cavity.

[0008] The lever-type locking mechanism includes a locking rod and a first elastic element. The locking rod is rotatably connected to the base body around a preset axis. The locking rod includes an operating arm and a locking arm. The locking arm is connected to the operating arm. The first elastic element is connected between the locking rod and the base body.

[0009] The male connector includes a male terminal, a housing, and a locking part. The locking part is disposed on the outer wall of the housing, and the male terminal is disposed inside the housing.

[0010] When the male connector and the female socket are plugged in, the housing portion is inserted into the first cavity, the male terminal mates with the female terminal and is electrically connected, the engaging portion is accommodated in the clearance groove, the locking arm stops the housing, and the elastic force of the first elastic member maintains the blocking state between the locking arm and the housing to temporarily fix the housing to the base.

[0011] Optionally, the base is provided with a slide rail and a booster assembly slidably connected to the slide rail;

[0012] The booster assembly includes a booster plate and a second elastic member. One end of the second elastic member is connected to the booster plate, and the other end is connected to the base. The elastic force of the second elastic member causes the booster plate to have a tendency to move from the second cavity to the first cavity.

[0013] The booster plate is annular, with its outer periphery connected to the slide rail and its inner periphery extending into the cavity. The inner hole of the booster plate is used for the female terminal to pass through, and the inner periphery of the booster plate forms a thrust surface that abuts against the male connector.

[0014] Optionally, the base includes a first base and a second base arranged sequentially along a first direction, the first base being detachably connected to the second base; the first base is provided with a first through hole, the second base is provided with a second through hole and a sliding cavity, one end of the second through hole near the first through hole is connected to the sliding cavity, the sliding cavity constitutes the slide rail, the pusher plate slides within the sliding cavity, the first through hole is connected to the second through hole, the first through hole constitutes the first cavity, and the second through hole constitutes the second cavity.

[0015] Optionally, along the first direction, the depth of the clearance groove is less than the depth of the first cavity, so that the bottom wall of the clearance groove blocks the male connector.

[0016] Optionally, the male connector includes a wire, an insertion end, and a receiving end, with the two ends of the wire connected to the insertion end and the receiving end, respectively. The insertion end is used to insert into the first cavity, and the receiving end is used to connect to an external device.

[0017] The engaging portion is located on the outer wall of the insertion end.

[0018] Optionally, the housing is formed with a first protrusion and a second protrusion arranged sequentially along the direction from the first cavity to the second cavity.

[0023] Optionally, the first elastic element is a compression spring.

[0024] This utility model provides a quick-connect structure for analog and digital signal electrical testing. Compared to connectors used with male connectors, the latter two methods have more engaging parts and stronger locking connections, making disassembly of the connected male connector and connector inconvenient. In this embodiment, after the male connector is inserted into the female socket, the engaging parts enter the clearance groove and do not engage with the female socket. The temporary fixation of the female socket and male connector is achieved through a lever-type locking mechanism. To remove the male connector, simply press the operating arm towards the base and pull the male connector outwards. This method offers the advantage of simple operation. Attached Figure Description

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figures 1 to 3 As shown, this utility model embodiment provides a quick-connect structure for analog and digital signal electrical testing, including a male connector 1 and a female socket 2 for plugging and mating. The female socket 2 includes a base, a female terminal 24, and a lever-type locking mechanism 3. The base has a cavity extending in a first direction, and the cavity includes a first cavity 211 and a second cavity 221. The first cavity 211 is used for the male connector 1 to be inserted, and the female terminal 24 is fixed in the second cavity 221. In this embodiment, the female terminal 24 includes multiple pins, and the second cavity 221 is formed by multiple through holes provided on the base.

[0035] In other embodiments, the female terminal 24 may be an integral plug-in terminal that directly plugs into the male connector 1.

[0036] The seat is provided with a clearance groove 25, which extends along a first direction and communicates with the first cavity 211; the lever-type locking mechanism 3 includes a locking rod 31 and a first elastic element 23. The locking rod 31 is rotatably connected to the seat about a preset axis. The locking rod 31 includes an operating arm 312 and a locking arm 311. The locking arm 311 is connected to the operating arm 312. The first elastic element 23 is connected between the locking rod 31 and the seat.

[0037] The locking arm 311 is used to stop the engagement with the male connector 1. When it is necessary to release the engagement between the locking arm 311 and the male connector 1, the operator applies external force to the operating arm 312 to drive the locking lever 31 to rotate, so that the locking arm 311 disengages from the male connector 1.

[0038] The male connector 1 includes a male terminal, a housing, and a locking part 14. The locking part 14 is disposed on the outer wall of the housing, and the male terminal is disposed inside the housing. When the male connector 1 and the female socket 2 are inserted, the housing is partially inserted into the first cavity 211, the male terminal engages with the female terminal 24 and is electrically connected, the locking part 14 is accommodated in the relief groove 25, the locking arm 311 stops the housing, and the elastic force of the first elastic member 23 maintains the blocking state between the locking arm 311 and the housing to temporarily fix the housing to the base.

[0039] In this embodiment, the first elastic element 23 is a spring plunger with a certain extension and retraction stroke. When the housing is inserted into the first cavity 211, the male terminal and the female terminal 24 contact each other, and the two are electrically connected and exchange signals. The engaging part 14 is directly inserted into the clearance groove 25. At this time, the first elastic element 23 drives the locking rod 31 to rotate, so that the operating arm 312 applies away from the seat, while the locking arm 311 approaches the seat until the locking arm 311 stops the seat.

[0040] Compared to the connector used with the male connector 1, the connection between the two is more complicated due to the larger number of engaging parts 14 and the stronger snap-fit ​​connection between the engaging parts 14 and the connector. This makes it difficult to disassemble the already connected male connector 1 and connector. In this embodiment, after the male connector 1 is inserted into the female socket 2, the engaging parts 14 enter the clearance groove 25 and do not snap-fit ​​with the female socket 2. The temporary fixation of the female socket 2 and the male connector 1 is achieved by a lever-type locking mechanism 3. To remove the male connector 1, simply press the operating arm 312 towards the base and then pull the male connector 1 outward. This method is simple to operate.

[0041] In this embodiment, as with the prior art, after the male connector 1 and the female socket 2 are plugged in, analog or digital signals are transmitted through the male and female terminals to perform electrical testing.

[0042] In one embodiment, the seat is provided with a slide rail and a booster assembly slidably connected to the slide rail; the booster assembly includes a booster plate and a second elastic member 32, one end of the second elastic member 32 is connected to the booster plate and the other end is connected to the seat, and the elastic force of the second elastic member 32 causes the booster plate to have a tendency to move from the second cavity 221 to the first cavity 211.

[0043] The push plate is annular, with its outer periphery connected to the slide rail and its inner periphery extending into the cavity. The inner hole of the push plate is used for the female terminal 24 to pass through. The inner periphery of the push plate forms a thrust surface that abuts against the male connector 1. Specifically, the inner periphery of the push plate abuts against the housing of the male connector 1 and does not cause mechanical interference to the male terminal.

[0044] In this embodiment, when the male connector 1 is inserted and the male connector 1 is locked to the female socket 2, the push plate applies a pushing force to the male connector 1, causing the male connector 1 to tend to move away from the female socket 2. When the locking arm 311 disengages from the seat, due to the elastic force of the second elastic element 32, the male connector 1 automatically moves outward from the first cavity 211, making it easy for a person to pull out the male connector 1.

[0045] In one embodiment, the seat includes a first seat 21 and a second seat 22 arranged sequentially along a first direction. The first seat 21 is detachably connected to the second seat 22. The first seat 21 is provided with a first through hole, and the second seat 22 is provided with a second through hole and a sliding cavity 222. The end of the second through hole near the first through hole is connected to the sliding cavity 222. The sliding cavity 222 constitutes the slide rail. The pusher plate slides in the sliding cavity 222. The first through hole is connected to the second through hole. The first through hole constitutes the first cavity 211, and the second through hole constitutes the second cavity 221.

[0046] In this embodiment, the split base body can easily install the booster plate and the first elastic element 23. When the booster plate is installed on the second base body 22, the first base body 21 is then fixed on the second base body 22 with bolts.

[0047] In one embodiment, the male connector 1 includes a wire 13, an insertion end 11, and a receiving end 12. The two ends of the wire 13 are respectively connected to the insertion end 11 and the receiving end 12. The insertion end 11 is used to insert into the first cavity 211, and the receiving end 12 is used to connect to an external device. The outer shell of the insertion end 11 forms a housing, and a male terminal is disposed within the insertion end 11. The receiving end 12 itself has a housing, and a terminal is disposed within the housing of the receiving end 12 for connecting to the cable of the charging port cover 9. The engaging portion 14 is disposed on the outer wall of the insertion end 11. The male connector 1 in this embodiment is a common connector structure.

[0048] In one embodiment, along the first direction, the depth of the clearance groove 25 is less than the depth of the first cavity 211, so that the bottom wall of the clearance groove 25 blocks the male terminal. In this embodiment, the depth of the clearance groove 25 does not need to be too deep, it is only necessary to ensure that after the male connector 1 is inserted into the female socket 2, the engaging portion 14 on the male connector 1 reaches the bottom of the clearance groove 25, at which time the clearance groove 25 can block the male connector 1.

[0049] In one embodiment, the housing is formed with a first protrusion 15 and a second protrusion 16 arranged sequentially along the direction from the first cavity 211 to the second cavity 221. The side surface of the second protrusion 16 away from the female terminal 24 is used to engage with the locking arm 311. The side surface of the first protrusion 15 near the locking rod 31 is lower than the side surface of the second protrusion 16 near the locking rod 31. In this embodiment, the first protrusion 15 and the second protrusion 16 form a step. When the male connector 1 is inserted, the locking arm 311 jumps from the side surface of the first protrusion 15 near the locking rod 31 to the side surface of the second protrusion 16 near the locking rod 31. The locking arm 311 first jumps from the upper surface of the first protrusion 15 to the upper surface of the second protrusion 16, and then stops on the outer surface of the second protrusion 16 away from the first protrusion 15.

[0050] In one embodiment, the locking rod 31 further includes a rotating shaft 34 and a protrusion. A rotating hole is provided in the middle of the length direction of the locking rod 31, the rotating shaft 34 passes through the rotating hole, and both ends of the rotating shaft 34 pass through the rotating hole and are connected to the seat body. The protrusion is provided in the middle of the length direction of the locking rod 31, and the protrusion is located on the side of the locking rod 31 closer to the seat body.

[0051] In this embodiment, the locking arm 311 and the operating arm 312 constitute the two ends of the locking rod 31, and the connection between the two is the middle of the locking rod 31. The rotating hole does not need to be set at the midpoint of the length direction of the locking rod 31, but only needs to be close to the middle of the length direction of the locking rod 31. In this embodiment, the rotating hole is located in the middle of the locking rod 31, but closer to the end of the locking arm 311 that is away from the operating arm 312.

[0052] In one embodiment, the lever-type locking mechanism 3 further includes an adjusting bolt 33. The locking rod 31 is provided with a threaded hole that passes through the locking rod 31. The adjusting bolt 33 is threadedly connected to the threaded hole and can pass through the end of the threaded hole near the seat and abut against the seat.

[0053] In this embodiment, when the length of the adjusting bolt 33 extending through the locking rod 31 in the direction of the seat is too long, compared to when the length of the adjusting bolt 33 extending through the locking rod 31 in the direction of the seat is short, the distance between the locking arm 311 and the seat is greater in the locked state. As a result, the locking arm 311 can more easily jump from the first protrusion 15 to the second protrusion 16, making it easier for the male connector 1 to be inserted into the female terminal 24.

[0054] In one embodiment, this utility model provides a charging port cover testing platform, including a test base 8 and the aforementioned quick-connect structure for analog and digital signal electrical testing. The female end socket 2 is inserted and installed on the test base 8, and the receiving end 12 is used to connect with the connection end of the charging port cover 9. In this embodiment, the charging port cover 9 is a charging port cover for new energy vehicles.

[0055] In other embodiments, a quick-connect structure for electrical testing of analog and digital signals can also be applied to other test equipment.

[0056] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
