Description

Technical Field

[0001] This application belongs to the field of electrical accessories technology, and more specifically, this application relates to an electrical connector. Background Technology

[0002] Electrical connectors are mainly used for circuit connections between cables and between cables and equipment in electrical or electronic equipment, enabling the transmission of low-frequency signals, high-frequency signals, and electrical energy (power). An electrical connector consists of two parts: a fixed-end connector (also known as a socket) and a free-end connector (also known as a plug). The connection and disconnection of the circuit are achieved through the mating and disassembly of the plug and socket.

[0003] The signal contacts on the plug and socket enable signal conduction, and the power contacts enable power connection. However, currently, when the plug and socket are separated, the signal contacts and power contacts disconnect simultaneously. This causes the control system to not have time to recognize the signal disconnection before the power contacts have already separated, which can easily lead to separation faults such as electric arcing. This affects the service life of the electrical connector and the connected equipment, and also poses a safety hazard of electric shock to the user. Utility Model Content

[0004] Embodiments of this application provide an electrical connector that controls the connection or disconnection of a first signal contact and a second signal contact via an assist wrench. When unlocking the plug and socket, the first and second signal contacts are first disconnected by rotating the assist wrench, causing the signal between the plug and socket to be disconnected first. Then, the connection between the plug and socket is disconnected, causing the power between the plug and socket to be disconnected. There is a time difference between the signal disconnection and the power disconnection, achieving delayed unlocking, avoiding hot-plugging, preventing electric arcs, and improving safety.

[0005] To achieve the aforementioned technical objectives, this application discloses an electrical connector, including a plug, a socket, and an assist wrench.

[0006] The plug is provided with plug signal contacts and plug power contacts, the plug signal contacts including a first signal contact and a second signal contact.

[0007] The socket is equipped with socket signal contacts and socket power contacts.

[0008] The first end of the assist wrench is rotatably connected to the first end of the plug, and the second end of the assist wrench can move toward or away from the second end of the plug under the action of an external force, so as to make the first signal contact and the second signal contact conduct or disconnect.

[0009] The rotation process of the power wrench relative to the plug includes a first position and a second position.

[0010] When the power assist wrench is in the first position, the first signal contact and the second signal contact are connected, the plug and the socket are inserted, and both the signal and power of the plug and the socket are connected.

[0011] When the power assist wrench is in the second position, the first signal contact and the second signal contact are disconnected, the plug and the socket are plugged in, and the signal of the plug and the socket is disconnected while the power is turned on.

[0012] The beneficial effects of this application are as follows:

[0013] The electrical connector of this application controls the first and second signal contacts to be connected or disconnected via an assist wrench. When the plug and socket are unlocked, the first and second signal contacts are first disconnected by rotating the assist wrench, so that the signal between the plug and socket is disconnected first. Then, the connection between the plug and socket is disconnected, so that the power between the plug and socket is disconnected. This creates a time difference between signal disconnection and power disconnection, achieving delayed unlocking, avoiding hot plugging and unplugging, preventing electric arcs, and improving safety.

[0022] The electrical connector provided in this application will be explained and described in detail below with reference to the accompanying drawings.

[0023] This embodiment specifically discloses an electrical connector, such as... Figures 1-6 As shown, the device includes a plug 1, a socket 2, and an assist wrench 3. The plug 1 is provided with a plug signal contact and a plug power contact. The plug signal contact includes a first signal contact and a second signal contact. The plug 1 specifically includes a plug housing 11, a first signal contact, a second signal contact, and a plug power contact. The first signal contact, the second signal contact, and the plug power contact are disposed inside the plug housing 11, and the ends of the second signal contact and the plug power contact can extend outside the plug housing 11.

[0024] The socket 2 is provided with a socket signal contact and a socket power contact. The socket 2 includes a socket housing 21 and the socket signal contact and the socket power contact, which are disposed inside the socket housing 21.

[0025] The second signal contact and the socket signal contact can abut or plug into each other to achieve contact and make the circuit conductive. Similarly, the plug power contact and the socket power contact can abut or plug into each other to achieve contact and make the circuit conductive. The second signal contact can be a pin, and the socket signal contact is a socket that mates with the second signal contact. They can conduct electricity when in contact and disconnect when separated. The plug power contact can be a pin, and the socket power contact is a socket that mates with the plug power contact. They can conduct electricity when in contact and disconnect when separated. The second signal contact can be a male pin, and the socket signal contact is a mating female pin; the plug power contact can be a male pin, and the socket power contact is a mating female pin.

[0026] The first end of the power wrench 3 is rotatably connected to the first end of the plug 1. The second end of the power wrench 3 can move toward or away from the second end of the plug 1 under the action of external force, so as to make the first signal contact and the second signal contact conduct or disconnect.

[0027] In this embodiment, the second signal contact is closer to the first end of the plug 1 than the first signal contact, and the first signal contact is closer to the second end of the plug 1 than the second signal contact. The plug power contact is located at the first end of the plug 1. The first end of the plug 1 is the end that is plugged into the socket 2, and the second end of the plug 1 is the end that is connected to the cable. The second end of the assist wrench 3 is a free end, and the user's hand can hold the second end of the assist wrench 3 to apply external force, so that the assist wrench 3 rotates relative to the plug 1.

[0028] The rotation process of the power wrench 3 relative to the plug 1 includes a first position and a second position. In this embodiment, when the power wrench 3 is in the first position, the second end of the power wrench 3 is in contact with the second end of the plug 1 or the distance between the second end of the power wrench 3 and the second end of the plug 1 is the smallest. When an external force (e.g., the user's hand) acts on the power wrench 3 and pushes the second end of the power wrench 3 to rotate from the first position to the direction away from the second end of the plug 1, it can rotate to the second position.

[0029] When the power wrench 3 is in the first position, the first signal contact and the second signal contact are connected, the plug 1 and the socket 2 are plugged in, preferably the plugging is closed, and the signals and power of the plug 1 and the socket 2 are both connected.

[0030] When the power wrench 3 is in the second position, the first signal contact and the second signal contact are disconnected, the plug 1 and the socket 2 are connected, and the signal of the plug 1 and the socket 2 is disconnected while the power is turned on.

[0031] When plug 1 and socket 2 are plugged in and closed, the assist wrench 3 is in the first position, the first and second signal contacts are conductive, the plug signal contact is conductive with the socket signal contact, and the plug power contact is conductive with the socket power contact. Both the signal and power of plug 1 and socket 2 are conductive. When plug 1 and socket 2 are unlocked, the user moves the second end of the assist wrench 3 away from the second end of plug 1. When the assist wrench 3 rotates to the second position, the first and second signal contacts disengage. At this point, the signal between plug 1 and socket 2 is disconnected. Then, when plug 1 and socket 2 are further separated, the plug power contact and socket power contact disengage, and the power of plug 1 and socket 2 is disconnected. There is a time difference between the signal disconnection and the power disconnection, achieving delayed unlocking, avoiding live plugging and unplugging, preventing electric arcing, improving safety, and extending the lifespan of the electrical connector and the connected equipment.

[0032] This application allows control of the connection and disconnection of the first and second signal contacts by manipulating the power-assisted wrench 3.

[0033] Optionally, an electrical connection bridge can be provided on the surface of the power-assisted wrench 3 near the plug 1. The first end of the electrical connection bridge can be connected to the second signal contact when in contact and disconnected when separated. The second end of the electrical connection bridge can be connected to the first signal contact when in contact and disconnected when separated. When the power-assisted wrench 3 is in the first position, the first end of the electrical connection bridge is in contact with the second signal contact and thus conducts, and the second end of the electrical connection bridge is in contact with the first signal contact and thus conducts, thereby achieving conduction between the first and second signal contacts. During the process of rotating the power-assisted wrench 3 from the first position to the second position, the second end of the electrical connection bridge is moved away from the first signal contact. When the power-assisted wrench 3 is in the second position, the second end of the electrical connection bridge is separated from the first signal contact and thus disconnected, and the first end of the electrical connection bridge is in contact with or separated from the second signal contact, thereby achieving disconnection between the first and second signal contacts.

[0034] Optional, such as Figure 5 and Figure 6 As shown, the electrical connector of this application also includes a detachably connected first electrical connector 41 and a second electrical connector 42. One of the first electrical connector 41 and the second electrical connector 42 is disposed on the plug 1 and connected to the first signal contact, and the other is disposed on the assist wrench 3 and connected to the second signal contact. The assist wrench 3 rotates relative to the plug 1 to make the first electrical connector 41 and the second electrical connector 42 conduct or disconnect. The first electrical connector 41 and the second electrical connector 42 can conduct when in contact and disconnect when separated. The electrical connector on the plug 1 is disposed near the second end of the plug 1, and the electrical connector on the assist wrench 3 is disposed near the second end of the assist wrench 3. When the first electrical connector 41 and the second electrical connector 42 are connected, the first signal contact and the second signal contact are connected; when the first electrical connector 41 and the second electrical connector 42 are disconnected, the first signal contact and the second signal contact are disconnected. When the power wrench 3 is in the first position, the second end of the power wrench 3 is in contact with the second end of the plug 1, or the distance between them is minimal. The first electrical connector 41 and the second electrical connector 42 are in contact, achieving electrical continuity, and the first signal contact and the second signal contact are also connected. When the power wrench 3 is in the second position, the second end of the power wrench 3 maintains a certain distance from the second end of the plug 1. The first electrical connector 41 and the second electrical connector 42 are separated, achieving electrical disconnection, and the first signal contact and the second signal contact are disconnected. If the power wrench 3 can continue to rotate from the second position away from the first position (i.e., continue to rotate from the second position away from the second end of the plug 1), both the first electrical connector 41 and the second electrical connector 42 are in a disconnected state.

[0035] The first electrical connector 41 may include a contact, and the second electrical connector 42 may include a conductive piece. When the power wrench 3 is in the first position, the conductive piece contacts the contact and conducts electricity. When the power wrench 3 is in the second position, the conductive piece disconnects from the contact.

[0036] The first electrical connector 41 can be a socket, and the second electrical connector 42 can be a pin that matches the socket; the first electrical connector 41 and the second electrical connector 42 can both be metal sheets. This application does not impose any special limitations on the specific form of the first electrical connector 41 and the second electrical connector 42, as long as they can make contact and conduct electricity.

[0037] In some optional embodiments, the rotation process of the assist wrench 3 relative to the plug 1 further includes a third position, with the second position located between the first and third positions. In this embodiment, when an external force (e.g., the user's hand) acts on the assist wrench 3, pushing the second end of the assist wrench 3 to rotate from the first position toward the second end away from the plug 1, the process may first rotate to the second position and then continue rotating until it reaches the third position.

[0038] like Figure 1 and Figure 2 As shown, when the power wrench 3 is in the first position, the plug 1 and the socket 2 are plugged in and closed, that is, the plug 1 and the socket 2 are completely closed. The second end of the power wrench 3 is in contact with the second end of the plug 1 or the distance between them is minimal. At this time, the second end of the electrical connection bridge on the power wrench 3 is in contact with the first signal contact, the first end of the electrical connection bridge is in contact with the second signal contact, or the first electrical connection 41 is in contact with the second electrical connection 42, so that the first signal contact and the second signal contact are connected. The second signal contact and the plug power contact are both located at the first end of the plug 1. The lower part of the first end of the plug 1 is plugged into the socket 2. The second signal contact is in contact with the socket signal contact (e.g., plugged in or abutted) to achieve connection, thereby making the plug signal contact and the socket signal contact connected. The signals of the plug 1 and the socket 2 are connected. The plug power contact and the socket power contact are in contact (e.g., plugged in or abutted) to achieve connection. The signals and power of the plug 1 and the socket 2 are both connected.

[0039] like Figure 3 and Figure 4As shown, when the power assist wrench 3 is in the second position, the second end of the power assist wrench 3 is a certain distance away from the second end of the plug 1. The second end of the electrical connection bridge on the power assist wrench 3 is separated from the first signal contact, and the first end of the electrical connection bridge is either in contact with or separated from the second signal contact. Alternatively, the first electrical connection 41 is separated from the second electrical connection 42, causing the first and second signal contacts to disconnect. At this time, the plug 1 and socket 2 remain plugged in. The second signal contact and the socket signal contact remain in contact and are conductive. The plug power contact and the socket power contact remain in contact and are conductive. At this time, the plug 1 and socket 2 can remain plugged in and closed. Alternatively, the plug 1 can move a certain distance away from the socket 2, creating a gap between the plug housing 11 and the socket housing 21, as long as the second signal contact and the socket signal contact, and the plug power contact and the socket power contact, are in contact. At this time, the signals of the plug 1 and socket 2 are disconnected, and the power of the plug 1 and socket 2 is conductive.

[0040] like Figure 5 and Figure 6 As shown, when the power wrench 3 is in the third position, the distance between the second end of the power wrench 3 and the second end of the plug 1 is greater than the distance between the second end of the power wrench 3 and the second end of the plug 1 when the power wrench 3 is in the second position. The second end of the electrical connection bridge on the power wrench 3 remains separated from the first signal contact, and the first end of the electrical connection bridge is separated from the second signal contact. Alternatively, the first electrical connection 41 and the second electrical connection 42 remain separated, and the first signal contact is disconnected from the second signal contact. During the movement of the power wrench 3 from the second position to the third position, the power wrench 3 can also drive the plug 1 to move away from the socket 2. When the power wrench 3 is in the third position, there is a certain distance between the lower part of the first end of the plug 1 and the socket 2, which separates the second signal contact from the socket signal contact. The second signal contact is disconnected from the socket signal contact, but the plug power contact and the socket power contact remain in contact, and the plug power contact and the socket power contact are connected.

[0041] Taking the case where plug 1 is above socket 2 as an example, the bottom ends of both the second signal contact and the plug power contact face socket 2. The tops of the socket signal contact and the socket power contact on socket 2 are flush, and the bottom end of the second signal contact can be higher than the bottom end of the plug power contact. Therefore, when the power wrench 3 rotates from the second position to the third position, causing plug 1 to move upward, the second signal contact and the socket signal contact first disconnect, while the plug power contact and the socket power contact remain conductive.

[0042] In this embodiment, when the power wrench 3 is in the first position, the first signal contact and the second signal contact are connected; when the power wrench 3 rotates to the second position, the first signal contact and the second signal contact are disconnected; when the power wrench 3 continues to rotate to the third position, the first signal contact and the second signal contact remain disconnected. That is, the first signal contact and the second signal contact are connected only when the power wrench 3 is in the first position; when the power wrench 3 is in other positions, both the first signal contact and the second signal contact are disconnected.

[0043] The lower part of the first end of the power wrench 3 can also slide to connect with the socket 2. When the power wrench 3 is in the first position, it can lock the plug 1 and the socket 2. During the rotation of the power wrench 3 from the second position away from the second end of the plug 1 to the third position, using the point of rotational connection between the first end of the power wrench 3 and the plug 1 as a fulcrum, the lower part of the first end of the power wrench 3 moves towards the second end of the plug 1. Since the socket 2 remains stationary relative to the plug 1, the sliding of the lower part of the first end of the power wrench 3 relative to the socket 2 can drive the plug 1 to move away from the socket 2. When the power wrench 3 rotates to the third position, the second signal contact is disconnected from the socket signal contact; however, the plug power contact and the socket power contact are connected. At this time, the signals of the plug and socket are completely disconnected, and the power of the plug and socket is connected.

[0044] When plug 1 and socket 2 are separated, the power contact of the plug and the power contact of the socket are disconnected, thus unlocking plug 1 and socket 2.

[0045] This embodiment of the application, through the setting of the assisted wrench 3, unlocks the plug 1 and socket 2 in the following steps: First, the assisted wrench 3 is rotated from the first position to the second position, causing the first and second signal contacts to disconnect. At this time, the plug signal contact and the socket signal contact can no longer conduct electricity, but the second signal contact and the socket signal contact remain in contact, and the plug power contact and the socket power contact are conductive. Then, as the assisted wrench 3 rotates from the second position to the third position, it causes the plug 1 to move away from the socket 2. When the assisted wrench 3 rotates to the third position, the second signal contact and the socket signal contact disconnect, and the plug power contact and the socket power contact are conductive. Finally, the plug 1 is unplugged from the socket 2, thus disconnecting the plug power contact and the socket power contact. The above operation ensures that the high-voltage circuit has sufficient time to disconnect and cut off the high-voltage current. This embodiment of the application adds a third position, further increasing the time difference between signal disconnection and power disconnection.

[0046] By differentiating the design of the second and third positions, there is a two-stage signal disconnection mechanism before the power is disconnected between plug 1 and socket 2, which further ensures the time difference between signal disconnection and power disconnection, thus enhancing safety.

[0047] This application implements delayed unlocking of electrical connectors, which provides a sufficient time difference between signal disconnection and power disconnection, avoiding hot-plugging and arcing, ensuring user safety, and extending the lifespan of electrical connectors and the devices connected to them.

[0048] This embodiment of the application, by setting three position states of the power-assisted wrench 3, ensures that even if the electrical connection bridge, the first electrical connector 41, and the second electrical connector 42 fail, the signal can be disconnected first in the third position, and then the plug 1 can be pulled out to disconnect the power. There is still a time difference between the two, which can still avoid hot plugging and unplugging, and extend the service life of the electrical connector and the equipment connected by the electrical connector.

[0049] In this embodiment, the power wrench 3 is detachably connected to the socket 2. When the plug 1 is unplugged from the socket 2, the power wrench 3 can be separated from the socket 2 together with the plug 1.

[0050] In some alternative embodiments, such as Figures 1-6 As shown, the power wrench 3 includes a top plate 31 and side plates 32 connected to the top plate 31 and respectively disposed on both sides of the top plate 31. The top plate 31 is located on the side of the plug 1 away from the socket 2, that is, the top plate 31 is above the plug 1. The side plates 32 are located on the same side of the plug 1 and the socket 2. The two side plates 32 can be perpendicular to the top plate 31. The two side plates 32 and the top plate 31 form a space with an open bottom that can accommodate a part of the plug 1 to strengthen the connection between the plug 1 and the socket 2. The side plate 32 is a bent plate, and the side plate 32 includes a first section 321 and a second section 322 connected together. The first section 321 is fixedly connected to the top plate 31, and the top of the second section 322 is connected to the first section 321. The second section 322 extends towards the socket 2 so that the second section 322 can be connected to the socket 2. The second segment 322 is rotatably connected to the plug 1 and slidably connected to the socket 2. The angle between the second segment 322 and the first segment 321 is set as needed, preferably 90°, as long as it ensures that the assist wrench 3 can smoothly rotate relative to the plug 1, slide relative to the socket 2, and drive the plug 1 to move away from the socket 2. In this embodiment, as... Figure 5 and Figure 6 As shown, when the assist wrench 3 is in the third position, the top plate 31 is perpendicular to the top surface of the plug 1. The second section 322 is detachably connected to the socket 2. When the plug 1 and the socket 2 are separated, the assist wrench 3 separates from the socket 2 along with the plug 1.

[0051] Optionally, the first segment 321, the second segment 322, and the top plate 31 form a clearance opening 303 on the side of the plug 1 away from the socket 2. That is, there is a horizontal distance between the top plate 31 and the second segment 322. This is used to allow the plug 1 to be cleared when the power wrench 3 rotates, ensuring that the power wrench 3 can rotate smoothly relative to the plug 1 and can accommodate the protruding part of the plug 1 (such as...). Figures 1-4 As shown in the figure, cables can be installed inside the protrusion to reduce the size of the electrical connector.

[0052] Optionally, the first section 321 of the side plate 32 is provided with multiple heat dissipation holes for heat dissipation.

[0053] The electrical connection bridge on the power wrench 3 is specifically set on the bottom surface of the top plate 31, and the ends of the first signal contact and the second signal contact are exposed on the top surface of the plug housing 11.

[0054] The first electrical connector 41 or the second electrical connector 42 on the plug 1 is specifically disposed on the top of the plug housing 11, and the first electrical connector 41 or the second electrical connector 42 on the power wrench 3 is disposed on the bottom surface of the top plate 31. The first electrical connector 41 or the second electrical connector 42 on the power wrench 3 can be electrically connected to the second signal contact on the plug 1 via a wire. The first electrical connector 41 or the second electrical connector 42 on the power wrench 3 rotates with the rotation of the power wrench 3. When the power wrench 3 rotates from the first position to the second position, the first electrical connector 41 and the second electrical connector 42 separate, and the first signal contact and the second signal contact disconnect. In this embodiment, the position of the first electrical connector 41 or the second electrical connector 42 on the power wrench 3 is closer to the second end of the power wrench 3 than the first end of the power wrench 3, so that the rotation stroke of the power wrench 3 from the first position to the second position is less than the rotation stroke from the second position to the third position, thereby increasing the time difference between signal disconnection and power disconnection.

[0055] In some alternative embodiments, such as Figures 1-6 As shown, mounting shafts 12 are symmetrically arranged on both sides of the plug 1. The mounting shafts 12 are symmetrically arranged on both sides of the plug housing 11. Mounting holes 301 are symmetrically opened on both sides of the power wrench 3. The mounting holes 301 are arranged on the second section 322 of the side plate 32. The mounting holes 301 correspond one-to-one with the mounting shafts 12. The power wrench 3 is sleeved on the mounting shafts 12 through the mounting holes 301 and can rotate around the mounting shafts 12.

[0056] The socket 2 has symmetrical guide protrusions 22 on both sides. The guide protrusions 22 are symmetrically arranged on both sides of the socket housing 21. The two sides of the power wrench 3 have symmetrical motion trajectory grooves 302. The motion trajectory grooves 302 are arranged on the second section 322 of the side plate 32. The motion trajectory grooves 302 correspond one-to-one with the guide protrusions 22. The power wrench 3 is sleeved on the guide protrusions 22 through the motion trajectory grooves 302 and can slide relative to the guide protrusions 22.

[0057] The second end of the motion track groove 302 is closer to the second end of the assist wrench 3 than its first end, and the distance from the mounting hole 301 to various points on the motion track groove 302 gradually increases from the second end of the motion track groove 302 to the first end of the motion track groove 302. For example... Figure 1 and Figure 2 As shown, when the power wrench 3 is in the first position, the guide boss 22 is at the second end of the motion trajectory groove 302; as Figure 3 and Figure 4 As shown, when the power wrench 3 rotates from the first position to the second position, the second end of the motion trajectory groove 302 can move slightly upward; when the power wrench 3 rotates from the second position to the third position, the motion trajectory groove 302 slides relative to the guide boss 22, causing the position of the guide boss 22 within the motion trajectory groove 302 to gradually transition from the second end to the first end; as shown Figure 5 and Figure 6 As shown, when the power wrench 3 rotates to the third position, the motion track groove 302 moves until the guide boss 22 is at the first end of the motion track groove 302. Since the distance from the mounting hole 301 to each point on the motion track groove 302 gradually increases from the second end to the first end of the motion track groove 302, the distance between the guide boss 22 and the mounting shaft 12 in the motion track groove 302 also gradually increases during the process of the power wrench 3 moving from the second position to the third position. Since the socket 2 is fixed, the mounting shaft 12 needs to move upward, which causes the plug 1 to move upward, causing the second signal contact and the socket signal contact to gradually separate.

[0058] In this embodiment, the motion trajectory groove 302 is arc-shaped, making the rotation of the assist wrench 3 relative to the plug 1 and its sliding relative to the socket 2 smoother. Figures 1-6 As shown, when the plug 1 and socket 2 are plugged in, the mounting shaft 12 is directly above the guide boss 22. The angle between the mounting shaft 12 and the line connecting the two ends of the motion trajectory groove 302 is 90°, so that when the power wrench 3 is rotated to the third position, the top plate 31 of the power wrench 3 is perpendicular to the top surface of the plug 1.

[0059] In some alternative embodiments, such as Figure 1 , Figure 3 and Figure 5As shown, the electrical connector also includes a first locking mechanism 5, which is used to lock the power wrench 3 in a first position to ensure the stability of the plug 1 and socket 2 connection and to lock the plug 1 and socket 2. The first locking mechanism 5 includes a first locking member 51 disposed on the power wrench 3 and a second locking member 52 disposed on the plug 1. The first locking member 51 is preferably disposed on the second end of the power wrench 3. Specifically, the first locking member 51 is disposed on the second end of the top plate 31, and the second locking member 52 is disposed on the top of the second end of the plug housing 11. The first locking member 51 and the second locking member 52 can lock together after contact to lock the power wrench 3 in the first position.

[0060] One first locking mechanism 5 may be provided, with the first locking member 51 located at the center of the second end of the top plate 31; or two first locking mechanisms 5 may be provided, with the first locking members 51 symmetrically arranged on both sides of the center line of the top plate 31.

[0061] Optionally, the first locking member 51 and the second locking member 52 can be engaged by hooking, snapping, magnetic attraction, or threaded connection.

[0062] When the first locking member 51 and the second locking member 52 are hooked and locked, the first locking member 51 is a hook set on the bottom surface of the top plate 31 with the hook head facing upwards, and the second locking member 52 is a hook set on the top of the plug housing 11 with the hook head facing downwards. The hook head of the second locking member 52 can hook the hook head of the first locking member 51, locking the power wrench 3 in the first position. Optionally, the surface of the first locking member 51 facing the second locking member 52 has a first inclined surface, which slopes downwards away from the second locking member 52. The surface of the second locking member 52 facing the first locking member 51 has a second inclined surface, which slopes downwards towards the first locking member 51. When the assist wrench 3 rotates from the second position to the first position, under the pressure of the user's hand, the first inclined surface and the second inclined surface come into contact. The first locking member 51 moves downwards along the second inclined surface until the hook of the first locking member 51 hooks with the hook of the second locking member 52, locking the assist wrench 3 in the first position and locking it with the plug 1. When the first locking member 51 and the second locking member 52 are released, the user pulls the second end of the assist wrench 3 away from the second end of the plug 1. The first locking member 51 moves with the assist wrench 3 away from the second end of the plug 1 until it separates from the second locking member 52.

[0063] To facilitate the release of the first locking member 51 and the second locking member 52, the inner surfaces of the hooks of the first locking member 51 and the second locking member 52 can be set as planes.

[0064] When the first locking member 51 and the second locking member 52 are engaged, one of the first locking member 51 and the second locking member 52 is a groove and the other is a protrusion that matches the groove. When the power wrench 3 is rotated to the first position, the protrusion is inserted into the groove and has an interference fit with the groove, locking the power wrench 3 in the first position and locking it with the plug 1.

[0065] When the first locking member 51 and the second locking member 52 are magnetically locked, they are mutually magnetic. The first locking member 51 is fixed to the bottom surface of the top plate 31 with its magnetic surface facing down, and the second locking member 52 is fixed to the top of the plug housing 11 with its magnetic surface facing up. When the power wrench 3 is rotated to the first position, the first locking member 51 and the second locking member 52 are magnetically locked, locking the power wrench 3 in the first position and locking it to the plug 1. Both the first locking member 51 and the second locking member 52 may be magnetic; one of the first locking member 51 and the second locking member 52 may also be a magnet, and the other may be an iron structure.

[0066] When the first locking member 51 and the second locking member 52 are threadedly connected, the first locking member 51 can be a bolt rotatably connected to the top plate 31 of the power wrench 3, and the bolt can be detachably connected to the power wrench 3. The second locking member 52 is a threaded hole opened on the top of the plug housing 11. When the power wrench 3 is rotated to the first position, the bolt is screwed into the threaded hole on the top of the plug housing 11, locking the power wrench 3 in the first position and locking it with the plug 1.

[0067] In some optional embodiments, the electrical connector further includes a first locking mechanism 5 and a second locking mechanism 6. The first locking mechanism 5 is used to lock the power wrench 3 in a first position. The first locking mechanism 5 includes a first locking member 51 disposed on the power wrench 3 and a second locking member 52 disposed on the plug 1. The first locking member 51 is disposed on the second end of the power wrench 3. Specifically, the first locking member 51 is disposed on the end of the second segment 322 of the top plate 31 away from the side plate 32. The second locking member 52 is disposed on the top of the plug housing 11. The first locking member 51 and the second locking member 52 can be locked together after contact to lock the power wrench 3 in the first position.

[0068] The second locking mechanism 6 is used to lock the power wrench 3 in the first position. The second locking mechanism 6 includes a third locking member 61 disposed on the power wrench 3 and a fourth locking member 62 disposed on the plug 1. The third locking member 61 is disposed on the second end of the power wrench 3. Specifically, the third locking member 61 is disposed on the second end of the top plate 31, and the fourth locking member 62 is disposed on the top of the plug housing 11. The third locking member 61 and the fourth locking member 62 can lock together after contact to lock the power wrench 3 in the first position.

[0069] The locking methods of the first locking member 51 and the second locking member 52 are different from those of the third locking member 61 and the fourth locking member 62.

[0070] The number of the first locking mechanism 5 and the second locking mechanism 6 can both be one, and the first locking mechanism 5 and the second locking mechanism 6 are symmetrically arranged about the center line of the plug 1 and the power wrench 3.

[0071] The number of first locking mechanisms 5 can be one, and the first locking mechanism 5 is located at the center of plug 1 and power wrench 3. The number of second locking mechanisms 6 can be two, and the two second locking mechanisms 6 are symmetrically arranged on both sides of the first locking mechanism 5.

[0072] This application embodiment sets up two locking mechanisms with different locking methods. If one locking mechanism fails, the other locking mechanism can still lock the power wrench 3 in the first position and lock it to the plug 1, thereby ensuring the stability of the connection between the plug 1 and the socket 2.

[0073] Optionally, the locking method of the first locking member 51 and the second locking member 52 is one of hook locking, snap locking, magnetic locking, and threaded connection locking, and the locking method of the third locking member 61 and the fourth locking member 62 is another of hook locking, snap locking, magnetic locking, and threaded connection locking. The specific forms of each locking method are described in the above embodiments and will not be repeated here.

[0074] like Figure 5 As shown, the first locking member 51 is a bolt rotatably connected to the power wrench 3, the second locking member 52 is a threaded hole on the top of the plug housing 11; the third locking member 61 is a hook on the bottom of the power wrench 3, and the fourth locking member 62 is a hook on the top of the plug housing 11. When the bolt is loose, the cooperation of the third locking member 61 and the fourth locking member 62 can still lock the power wrench 3 in the first position, ensuring that the plug 1 and the socket 2 are in the plugged-in closed state.

[0075] In some alternative embodiments, such as Figures 1-6 As shown, the second end of the power-assisted wrench 3 is provided with a latch 304, the bottom surface of which is higher than the bottom surface of other parts of the second end of the power-assisted wrench 3. The top surface of the latch 304 may also be higher than the top surface of other parts of the second end of the power-assisted wrench 3. The latch 304 is disposed on the second end of the top plate 31. Preferably, the latch 304 is disposed at the center of the second end of the top plate 31, and the bottom surface of the latch 304 is higher than the bottom surface of other parts of the top plate 31. When the power-assisted wrench 3 is in the first position and the bottom surface of the top plate 31 is in contact with the top surface of the plug housing 11, there is a gap between the bottom surface of the latch 304 and the top surface of the plug housing 11, which facilitates the user's hand to grip the latch 304 and operate the power-assisted wrench 3.

[0076] When the handle portion 304 is located at the center of the second end of the top plate 31, if the first locking mechanism 5 is located at the center of the second end of the plug 1 and the power wrench 3, and the first locking member 51 is located on the handle portion 304, the bottom surface of the handle portion 304 is higher than the bottom surface of other parts of the top plate 31, which also facilitates the setting of the first locking member 51; if the first locking mechanism 5 and / or the second locking mechanism 6 are located on both sides of the center line of the plug 1 and the power wrench 3, the first locking member 51 and / or the third locking member 61 can be symmetrically arranged on both sides of the handle portion 304.

[0077] Optionally, the top of the handle 304 may be provided with anti-slip texture and patterned guidance, the patterned guidance being used to guide the direction of operating the power-assisted wrench 3.

[0078] Furthermore, the handle portion 304 and the other parts of the second end of the assist wrench 3 form a notch 305, or the edge of the handle portion 304 protrudes beyond the edge of the other parts of the second end of the assist wrench 3, that is, the edge of the handle portion 304 is not flush with the edge of the other parts of the top plate 31, which facilitates the user's finger exertion. The shape of the handle portion 304 protruding beyond the other parts of the second end of the assist wrench 3 can be semi-circular, semi-elliptical, square, rectangular, etc., and this application does not impose any special limitations.

[0079] like Figure 1 and Figure 3 As shown, a groove 3041 can also be provided on the upper edge of the handle 304 to accommodate the user's fingertips, making it easier for the user to apply force to turn the power wrench 3.

[0080] In some alternative embodiments, such as Figures 1-6 As shown, the electrical connector also includes a limiting mechanism 7 for locking the power wrench 3 in a third position. The limiting mechanism 7 includes a first limiting member 71 and a second limiting member 72. The first limiting member 71 is disposed on the plug 1, and the second limiting member 72 is disposed on the power wrench 3. The second limiting member 72 rotates with the power wrench 3 to lock or unlock with the first limiting member 71. When the power wrench 3 rotates to the third position, the second limiting member 72 locks with the first limiting member 71 (e.g., ...). Figure 5 and Figure 6 As shown), when the power wrench 3 is in other positions, the second limit member 72 is unlocked from the first limit member 71.

[0081] Optionally, the first limiting member 71 is a limiting groove provided on the plug 1, and the second limiting member 72 is a limiting protrusion provided on the power wrench 3. The limiting protrusion can engage with the limiting groove to lock the power wrench 3 in the third position. In order not to affect the rotation of the power wrench 3, a limiting block 73 can be provided on the plug housing 11, and a limiting groove is provided on the limiting block 73; the second limiting member 72 is provided on the second section 322 of the side plate 32 of the power wrench 3, with the opening of the limiting groove facing the second section 322. When the power wrench 3 rotates to the third position, the limiting protrusion engages with the limiting groove to achieve locking. To unlock, the user rotates the power wrench 3, causing the limiting protrusion to rotate out of the limiting groove and unlock. Preferably, the limiting groove is an arc-shaped groove, and the limiting protrusion is an arc-shaped protrusion that matches the shape of the limiting groove.

[0082] The locking method of the first limiting member 71 and the second limiting member 72 can also be hook locking or magnetic locking.

[0083] The method of using the electrical connector in this embodiment is as follows:

[0084] Initially, the power assist wrench 3 can be in any position on the plug 1. When the plug 1 is inserted into the socket 2, the movement trajectory groove 302 of the power assist wrench 3 is fitted onto the guide boss 22 of the socket 2. Adjusting the position of the power assist wrench 3 so that it is in the first position, such as... Figure 1 and Figure 2 As shown, plug 1 and socket 2 are plugged in and closed, and the power wrench 3 locks plug 1 and socket 2. At this time, the two ends of the electrical connection bridge are in contact with the first signal contact and the second signal contact respectively, or the first electrical connector 41 and the second electrical connector 42 are in contact, so that the first signal contact is connected to the second signal contact, the second signal contact is connected to the socket signal contact, the plug signal contact is connected to the socket signal contact, and the plug power contact is connected to the socket power contact. That is, the signals and power of plug 1 and socket 2 are both connected.

[0085] When unlocking the electrical connector, first turn the second end of the assist wrench 3 away from the second end of plug 1, so that it is rotated to the second position, such as... Figure 3 and Figure 4 As shown, the second end of the electrical connection bridge separates from the first signal contact, or the first electrical connection 41 and the second electrical connection 42 separate, causing the first and second signal contacts to disconnect, the second signal contact and the socket signal contact to conduct, and the plug power contact and the socket power contact to conduct; then, the assist wrench 3 is rotated from the second position away from the second end of the plug 1, the assist wrench 3 drives the plug 1 to move away from the socket 2, when the assist wrench 3 rotates to the third position, as... Figure 5 and Figure 6As shown, the second signal contact is disconnected from the socket signal contact, while the plug power contact and the socket power contact remain conductive; finally, the plug 1 and the power wrench 3 are pulled off the socket 2, and the plug power contact and the socket power contact are disconnected.

[0086] This application adds an assist wrench 3 to the electrical connector, dividing the unlocking of the electrical connector into at least two steps: first, disconnecting the first and second signal contacts to disconnect the signal; then, unplugging the plug 1 from the socket 2 to disconnect the plug power contactor from the socket power contactor. Alternatively, first, disconnecting the first and second signal contacts to disconnect the signal; then, disconnecting the second signal contactor from the socket signal contactor to completely disconnect the signal; finally, unplugging the plug 1 from the socket 2 to disconnect the plug power contactor from the socket power contactor. This creates a time difference between signal disconnection and power disconnection, achieving delayed unlocking, avoiding live plugging and unplugging, preventing electric arcing, and improving safety.
