[0002] This disclosure claims priority to Chinese Patent Application No. 202510108814.5, filed on January 22, 2025, the contents of which are incorporated herein by reference in their entirety. Technical Field

[0003] The embodiments disclosed herein relate to, but are not limited to, the field of wireless communication technology, specifically to power connectors and electrical devices, and more particularly to probe-type power connectors and electrical devices having the probe-type power connector. Background Technology

[0004] With the increasing demand for wireless communication services and the development of wireless communication technologies, base stations have evolved from low-power integrated base stations (BTS) to high-power distributed base stations (separate Baseband Unit, BBU, and Remote Radio Unit, RRU / Active Antenna Unit, AAU). The separation of the radio frequency unit (RRU / AAU) from the baseband unit (BBU) not only changes the installation location of related equipment but also places higher demands on these active devices, including adapting to outdoor and even tower platform operating environments. Therefore, for the RRU / AAU, the power connector design must be able to support greater power consumption and current carrying capacity while ensuring ease and safety during installation.

[0005] Currently, the main types of power connectors on the market include spring-loaded, screw-loaded, and wrench-loaded types. However, with the increasing power consumption of RRU / AAU, existing cables have been expanded to support current carrying capacities of 50A and 80A, and 2*16mm connectors have been adopted. 2 2*25mm 2 Conductive cables with larger wire diameters. Traditional cables typically consist of multiple layers, including an outer sheath, a metal shielding layer, an insulation layer, and positive and negative conductors. This makes the installation process of traditional cables complex and cumbersome, increasing the difficulty of construction and the risk of misoperation, which may lead to poor contact or even safety hazards.

[0006] The existing cable installation process is quite cumbersome. For example, it may include estimating the cable length from the power supply end to the power receiving end, stripping the outer sheath of the cable, leaving the exposed metal shielding layer, crimping the tubular terminals, installing it to the connector plug, and tightening the screws. These operations are not only time-consuming, but also have extremely high requirements for the standardization of operation. If the operation is not standardized, such as inconsistent wire lengths, uneven copper wire cutting, wire filaments, mismatched terminal specifications, unsuitable crimping tools, cables not inserted to the appropriate depth, or screws not tightened, it may lead to poor contact between the cable and the connector, causing local temperature rise of the connector or even burning and fire. Summary of the Invention

[0007] This disclosure provides a power connector and an electrical device.

[0008] In a first aspect, embodiments of this disclosure provide a power connector, comprising: a housing having a plug hole; a foolproof slider configured to contact a cable inserted into the plug hole and slide within the plug hole between a first position and a second position along the insertion direction of the cable or along a direction opposite to the insertion direction; and an elastic member configured to abut against the foolproof slider and elastically deform under the action of the foolproof slider, wherein when the foolproof slider is in the first position, the cable is disconnected from the power terminal of the power connector, and when the foolproof slider is in the second position, the elastic member elastically deforms and the cable is electrically connected to the power terminal of the power connector.

[0009] Secondly, embodiments of this disclosure provide an electrical device including the power connector described above.

[0010] According to embodiments of this disclosure, the cooperative operation of the foolproof slider and the elastic element of the power connector effectively avoids poor contact problems caused by improper cable insertion. Furthermore, electrical connection is only achieved when the cable is correctly inserted, causing the foolproof slider to reach the second position and the elastic element to deform, reducing the possibility of connection failures due to installation errors. When the foolproof slider is in the first position, the cable is disconnected from the power terminal, reducing electrical safety hazards that may arise from incorrect connections. Compared to traditional power connectors that require complex operations such as wire stripping, terminal crimping, and screw tightening, when using the power connector of this disclosure, the operator only needs to correctly insert the cable into the insertion hole; the mechanical structure of the foolproof slider and the elastic element is sufficient to complete a reliable connection between the cable and the power connector, eliminating the need for excessive specialized tools and complex operating procedures, thus reducing the skill requirements for operators. Especially in scenarios such as large-scale base station installations, this can significantly shorten installation time and reduce labor costs. Attached Figure Description

The reference numerals themselves do not constitute a limitation on the technical solutions of the embodiments of this disclosure.

[0028] In the field of wireless communication technology, the power connector of a base station is a key component to ensure the normal operation of the base station. As base stations shift from low-power integrated base stations to high-power distributed base stations, such as the separation of RRU / AAU from BBU and the installation location of related equipment tending to be outdoors or even on tower platforms, higher requirements are placed on the power connector.

[0029] In some related technologies, spring-loaded power connectors have a relatively simple structure. However, for high-current, large-diameter cable connections, the contact reliability of the springs is not high. With prolonged use or exposure to external factors such as vibration, the springs may loosen, leading to increased contact resistance and subsequently localized temperature rise, affecting equipment performance and stability. Screw-type power connectors require screwdrivers and other tools to tighten the screws during cable installation, which is cumbersome. Inconsistent screw tightening can cause uneven contact pressure between the cable and connector, easily resulting in poor contact. Furthermore, in outdoor environments, screws may be difficult to remove due to rust, increasing maintenance difficulty. While wrench-type power connectors are easier to operate to some extent, they require a certain amount of space. In confined installation locations, the use of wrenches may be limited, and they also suffer from poor contact reliability due to loose connections.

[0030] In view of the above problems, it is necessary to develop a power connector that not only simplifies the cable installation process and reduces the requirements for operational specifications, but also has physical foolproof features to reduce the possibility of misoperation, thereby ensuring the safety and reliability of the connection.

[0031] In a first aspect, embodiments of this disclosure provide a power connector 100. As shown in FIG1, the power connector 100 includes: a housing 101 having a cable insertion hole 101a; a foolproof slider 104 configured to contact a cable inserted into the cable insertion hole 101a and slide within the cable insertion hole 101a between a first position and a second position along a cable insertion direction F or in a direction opposite to the insertion direction F; and an elastic member 103 configured to abut against the foolproof slider 104 and elastically deform under the action of the foolproof slider 104. When the foolproof slider 104 is in the first position, the cable is disconnected from the power terminal 107 of the power connector 100; when the foolproof slider 104 is in the second position, the elastic member 103 elastically deforms and the cable is electrically connected to the power terminal 107 of the power connector 100.

[0032] Referring to Figure 1 and Figures 7a and 7b, which schematically illustrate the process of inserting a cable into the power connector provided in an embodiment of this disclosure, in this embodiment, the housing 101 serves as the external structure of the power connector 100, protecting the internal components and providing mechanical support. The insertion hole 101a provided on the housing 101 is the channel for inserting the cable 200. The size and shape of the insertion hole 101a must be adapted to the cable specifications to ensure that the cable can be smoothly inserted and maintain a relatively stable position during insertion. Here, the cable can be a power cable, a communication cable, or any other cable.

[0033] The foolproof slider 104 is located inside the socket 101a and can contact the cable 200 inserted into the socket 101a. The foolproof slider 104 can slide between a first position (see Figure 7a) and a second position (see Figure 7b) within the socket 101a, and can slide along the insertion direction F of the cable 200 or in the opposite direction. When the cable 200 is initially inserted, the foolproof slider 104 is subjected to the force of the cable 200. If the cable 200 is not fully inserted to the bottom of the socket 101a, the foolproof slider 104 cannot receive sufficient force to move to the second position, thus preventing accidental energization. If the diameter of the cable 200 is too large or too small, it may not align correctly within the socket 101a, thus affecting the normal sliding of the foolproof slider 104. For example, a cable with an excessively large diameter may get stuck at the entrance of the socket 101a, while a cable with an excessively small diameter may not allow the foolproof slider 104 to receive sufficient force. If the cable 200 is bent, kinked, or otherwise physically deformed, it may hinder its smooth insertion, causing the foolproof slider 104 to remain in the first position to avoid electrical safety hazards caused by irregular contact. Therefore, if the cable 200 is not inserted properly or does not meet the requirements, the foolproof slider 104 will remain in the first position. At this time, the foolproof slider 104 prevents the cable from connecting to the power terminal 107, ensuring that accidental power is not caused by incorrect insertion. When the cable 200 is correctly inserted to the appropriate depth, the force applied by the cable 200 will cause the foolproof slider 104 to slide to the second position, thereby electrically connecting the cable 200 to the power terminal 107, as shown in Figure 7b.

[0034] The elastic element 103 can cooperate with the foolproof slider 104. The elastic element 103 is configured to abut against the foolproof slider 104. When the foolproof slider 104 is in the first position, as shown in Figure 7a, the elastic element 103 is in its initial state and no elastic deformation occurs. As the foolproof slider 104 moves to the second position under the action of the inserted cable 200, as shown in Figure 7b, the foolproof slider 104 applies pressure to the elastic element 103, causing the elastic element 103 to elastically deform. This elastic deformation provides a certain degree of buffering and self-adaptation for the connection structure of the power connector 100. Here, parameters such as the elastic coefficient of the elastic element 103 need to be designed and tested to ensure that the elastic element 103 can accurately deform and reset under the action of the foolproof slider 104, thereby achieving reliable electrical connection and disconnection functions. The elastic element 103 can be a U-shaped spring, a spring, or any other suitable elastic structure.

[0035] According to embodiments of this disclosure, the cooperative operation of the foolproof slider 104 and the elastic element 103 of the power connector 100 can effectively prevent poor contact caused by improper insertion of the cable 200. When using the power connector 100 of this disclosure, electrical connection is only achieved when the cable 200 is correctly inserted, the foolproof slider 104 reaches the second position, and the elastic element 103 deforms, reducing the possibility of connection failure caused by installation errors. When the foolproof slider 104 is in the first position, the cable 200 is disconnected from the power terminal 107, reducing electrical safety hazards that may be caused by incorrect connection. Compared with traditional power connectors that require complex operations such as wire stripping, terminal crimping, and screw tightening, when using the power connector 100 of this disclosure, the operator only needs to correctly insert the cable 200 into the insertion hole 101a, and the connection can be completed by the mechanical action of the foolproof slider 104 and the elastic element 103, without the need for excessive professional tools and complex operating steps, reducing the skill requirements for operators. Especially in scenarios such as large-scale base station installations, it can significantly shorten installation time and reduce labor costs.

[0036] In some embodiments, as shown in FIG1, a conductive probe 105 is provided on the elastic member 103, which is electrically connected to the cable 200 inserted into the insertion hole 101a. The conductive probe 105 extends in the insertion hole 101a in a direction opposite to the insertion direction F of the cable 200, such that the tip of the conductive probe 105 faces the opening end of the insertion hole 101a.

[0037] In the above embodiment, a conductive probe 105 is provided on the elastic member 103. The conductive probe 105 is designed to extend within the insertion hole 101a in a direction opposite to the insertion direction F of the cable 200. Furthermore, as an electrical contact component, the conductive probe 105 is designed to directly connect with the cable 200 inserted into the insertion hole 101a. Since the tip of the conductive probe 105 faces the opening of the insertion hole 101a, the cable 200 first contacts the tip of the conductive probe 105 when inserted. Therefore, as the cable 200 gradually penetrates deeper into the insertion hole 101a, the conductive probe 105 inserts deeper and deeper into the cable 200, ensuring a tighter and more stable electrical contact. Because the tip of the conductive probe 105 faces the opening of the insertion hole 101a, during the insertion of the cable 200, the conductive probe 105 automatically penetrates the positive and negative conductors (multi-strand copper wires) of the cable 200, ensuring a reliable electrical contact between them. This method avoids the process of stripping the insulation layer and crimping the terminals required in the traditional cable installation process, reducing the risk of poor contact due to improper manual operation.

[0038] In some embodiments, as shown in FIG1, the elastic member 103 has a first end 103a and a second end 103b. A conductive probe 105 is provided on the side of the first end 103a facing the insertion hole 101a, which can be electrically connected to the cable 200 inserted into the insertion hole 101a. The second end 103b is configured to abut against the anti-fool slider 104, so that the elastic member 103 undergoes elastic deformation under the action of the anti-fool slider 104.

[0039] In the above embodiment, the elastic member 103 has a first end 103a and a second end 103b. The first end 103a of the elastic member 103 faces the insertion hole 101a, and a conductive probe 105 is provided on the side facing the insertion hole 101a. The second end 103b of the elastic member 103 is configured to abut against the foolproof slider 104, that is, the second end 103b of the elastic member 103 is in physical contact with the foolproof slider 104. When the foolproof slider 104 moves from the first position to the second position due to the insertion of the cable 200, the foolproof slider 104 applies pressure to the elastic member 103, causing the elastic member 103 to deform. This elastic deformation allows the foolproof slider 104 to move between the first position and the second position, while providing support and reset elasticity for the foolproof slider 104. The foolproof slider 104 abuts against the second end 103b of the elastic member 103. When the foolproof slider 104 is subjected to an external force (such as the force caused by the insertion of the cable 200), the foolproof slider 104 will push the second end 103b of the elastic member 103, causing the elastic member 103 to undergo elastic deformation. In this way, the foolproof slider 104 can slide between a first position and a second position within the insertion hole 101a along the insertion direction F of the cable 200 or in a direction opposite to the insertion direction F.

[0040] In some embodiments, the elastic element 103 is a U-shaped spring sheet, with the second end 103b of the U-shaped spring sheet being higher than the first end 103a, so that the foolproof slider 104 can pass above the first end 103a of the U-shaped spring sheet and abut against the second end 103b of the U-shaped spring sheet.

[0041] Because the conductive probe 105 is disposed on the first end 103a of the elastic member 103 and the first end 103a faces the insertion hole 101a, the conductive probe 105 can make a direct and reliable electrical connection with the cable 200 when the cable 200 is inserted into the insertion hole 101a. At the same time, the fixed connection between the conductive probe 105 and the elastic member 103 makes the structure of the power connector 100 more compact, reduces the risk of possible loose connection or open circuit, and thus provides a continuous and stable power supply for the device.

[0042] In some embodiments, as shown in FIG1, the foolproof slider 104 includes a first portion 104a and a second portion 104b. The first portion 104a is provided with an opening 104c allowing the conductive probe 105 to pass through, and is configured to contact the cable 200 inserted into the insertion hole 101a to receive a force applied by the cable 200, causing the foolproof slider 104 to move from a first position to a second position under the action of the force. The second portion 104b is configured to abut against a second end 103b of the elastic member 103, so that the force applied by the cable 200 is transmitted via the foolproof slider 104 to the second end 103b of the elastic member 103.

[0043] In the above embodiment, the foolproof slider 104 of the power connector 100 includes a first portion 104a and a second portion 104b. The first portion 104a is provided with an opening 104c that allows a conductive probe 105 to pass through. When the cable 200 is inserted, the conductive probe 105 contacts the positive and negative wires of the cable 200 through the opening 104c, while ensuring that the conductive probe 105 does not obstruct the sliding of the foolproof slider 104. The first portion 104a directly contacts the cable 200 inserted into the plug hole 101a and receives the force applied by the cable 200. As the cable 200 gradually penetrates deeper into the plug hole 101a, the force applied by the cable 200 causes the foolproof slider 104 to move from a first position to a second position. The second portion 104b is configured to abut against the second end 103b of the elastic member 103. When the foolproof slider 104 moves due to the insertion of the cable 200, the second portion 104b pushes the second end 103b of the elastic member 103, causing the elastic member 103 to elastically deform. The force applied by inserting the cable 200 is transmitted through the first part 104a of the anti-foolproof slider 104 to the second part 104b, and then from the second part 104b to the second end 103b of the elastic member 103, which ultimately causes the elastic member 103 to deform, so that the cable 200 establishes an electrical connection with the power terminal 107.

[0044] Because the force applied when the cable 200 is inserted first acts on the first part 104a of the foolproof slider 104, and then is transmitted to the second end 103b of the elastic element 103 through the second part 104b, it can absorb and buffer the impact force during the insertion of the cable 200, reducing damage to the internal structure of the power connector. At the same time, this force transmission method also ensures the stability and reliability of the structure, making the entire connection process between the cable 200 and the power connector 100 smoother. The combination of the first part 104a and the second part 104b of the foolproof slider 104 with the conductive probe 105 and the elastic element 103 makes the overall structure of the power connector 100 more compact, which is beneficial for the miniaturization design of the power connector 100.

[0045] In some embodiments, as shown in FIG1, the second end 103b of the elastic member 103 has an extension portion 103c extending toward the power terminal 107. The power terminal 107 has a conductive clip 107a, and when the foolproof slider 104 is in the second position, the extension portion 103c of the second end 103b of the elastic member 103 is inserted into the conductive clip 107a of the power terminal 107, thereby electrically connecting the power terminal 107 to the elastic member 103.

[0046] In the above embodiment, the second end 103b of the elastic member 103 of the power connector 100 has an extension portion 103c extending toward the power terminal 107. The power terminal 107 has a conductive clip 107a, which serves as an interface for receiving the extension portion 103c of the elastic member 103. When the foolproof slider 104 moves to the second position, the extension portion 103c can be accurately inserted into the conductive clip 107a of the power terminal, thereby realizing the electrical connection between the cable 200 and the power terminal 107.

[0047] When cable 200 is inserted into socket 101a and the foolproof slider 104 is moved from the first position to the second position, the foolproof slider 104 applies force to the elastic element 103, causing the elastic element 103 to deform. As the elastic element 103 deforms, the extension 103c of the second end 103b of the elastic element 103 is pushed towards the power terminal 107 and ultimately inserted into the conductive clip 107a of the power terminal 107. This insertion action establishes a direct electrical connection between the elastic element 103 and the power terminal 107, thereby electrically connecting cable 200 to the power terminal 107. The tight fit between the extension 103c of the elastic element 103 and the conductive clip 107a of the power terminal 107 ensures a stable electrical connection even under slight vibration or environmental changes. This design reduces the possibility of poor contact and improves the reliability of the electrical connection.

[0048] In some embodiments, as shown in FIG8, the extension portion 103c of the second end 103b of the elastic member 103 has a limiting protrusion 103d structure, the limiting protrusion 103d being configured to cooperate with the conductive clip 107a of the power terminal 107, so that the power terminal 107 is electrically connected to the elastic member 103, thereby electrically connecting the power terminal 107 to the cable 200.

[0049] In the above embodiment, a limiting protrusion 103d is provided near the end of the extension portion 103c. This limiting protrusion 103d makes the fit between the extension portion 103c and the conductive clamp 107a of the power terminal 107 tighter and more precise. The conductive clamp 107a not only needs to have good conductivity, but also needs to cooperate with the limiting protrusion 103d to achieve a reliable electrical connection. The cooperation between the limiting protrusion 103d and the conductive clamp 107a can improve the stability of the electrical connection. When the limiting protrusion 103d and the conductive clamp 107a cooperate, the limiting protrusion 103d can prevent the extension portion 103c from accidentally coming out of the conductive clamp 107a. In addition, this structure can reduce connection loosening caused by factors such as equipment vibration and external interference. The design of the limiting protrusion 103d also has a positioning function. The limiting protrusion 103d can only engage with the conductive clamp 107a when the extension portion 103c is inserted into the conductive clamp 107a in the correct position and angle, thereby ensuring the correctness of the electrical connection.

[0050] In some embodiments, as shown in FIG2, a spring 208 is provided between the second end 103b of the elastic member 103 and the housing 101 to increase the rebound force of the elastic member 103.

[0051] In the above embodiment, a spring 208 is provided between the second end 103b of the elastic element 103 and the housing 101. The spring 208 provides additional restoring force to the elastic element 103. The two ends of the spring 208 are connected to the second end 103b of the elastic element 103 and the housing 101, respectively. When the elastic element 103 undergoes elastic deformation, the spring 208 will deform accordingly. When the elastic element 103 undergoes elastic deformation due to external force (such as the insertion of the cable 200 pushing the anti-foolproof slider 104, thereby deforming the elastic element 103), the spring 208 will be compressed or stretched, storing elastic potential energy. When the external force disappears, the spring 208 releases the stored elastic potential energy, which, together with the elasticity of the elastic element 103 itself, provides a stronger restoring force to the elastic element 103, enabling the elastic element 103 to return to its original state more quickly and improving the recovery speed of the elastic element 103. The rebound force of spring 208 ensures that the elastic element 103 can reliably return to its initial position after multiple operations, avoiding problems such as inaccurate positioning of the foolproof slider 104 and unstable electrical connection caused by the weakening of the elasticity of the elastic element 103. Spring 208 can, to a certain extent, compensate for the insufficient elastic performance of the elastic element 103 itself or the elasticity changes caused by environmental factors (such as temperature changes affecting the elasticity of the elastic element 103).

[0052] In some embodiments, referring to Figures 1 and 3, the power connector 100 includes a foolproof slider 304 instead of a foolproof slider 104, and a conductive probe 105 is disposed on the foolproof slider 304 for electrical connection with a cable 200 inserted into the insertion hole 101a. The conductive probe 105 extends within the insertion hole 101a in a direction opposite to the insertion direction F of the cable 200, such that the tip of the conductive probe 105 faces the opening end of the insertion hole 101a.

[0053] In the above-described embodiment, the conductive probe 105 is disposed on the foolproof slider 304. The conductive probe 105 is designed to extend within the insertion hole 101a in a direction opposite to the insertion direction F of the cable 200. Furthermore, as an electrical contact component, the conductive probe 105 is designed to directly connect with the cable 200 inserted into the insertion hole 101a. Since the tip of the conductive probe 105 faces the opening of the insertion hole 101a, the cable 200 will first contact the tip of the conductive probe 105 when inserted. Therefore, as the cable 200 gradually penetrates deeper into the insertion hole 101a, the conductive probe 105 will penetrate deeper and deeper into the cable 200, thereby ensuring a tighter and more stable electrical contact. Because the tip of the conductive probe 105 faces the opening of the insertion hole 101a, during the insertion of the cable 200, the conductive probe 105 will automatically pierce the positive and negative wire cores (multi-strand copper wires) of the cable 200, ensuring a reliable electrical contact between them. This method avoids the process of stripping the insulation layer and crimping the terminals required in the traditional cable installation process, reducing the risk of poor contact due to improper manual operation.

[0054] In some embodiments, referring to Figures 1 and 3, the power connector 100 includes an elastic element 307 instead of an elastic element 103, and the foolproof slider 304 includes a first portion 304a and a second portion 304b. A conductive probe 105, capable of electrical connection with a cable 200 inserted into the connector hole 101a, is provided on the side of the first portion 304a facing away from the connector hole 101a. The side of the first portion 304a facing away from the connector hole 101a abuts against the elastic element 307, and the first portion 304a is configured to contact the cable 200 inserted into the connector hole 101a to receive a force applied by the cable 200, causing the foolproof slider 304 to move from a first position to a second position under the action of the force. The second portion 304b extends along the insertion direction F of the cable 200 and is configured such that when the foolproof slider 304 is in the first position, the second portion 304b is disconnected from the power terminal 107 of the power connector 100, and when the foolproof slider 304 is in the second position, the second portion 304b is electrically connected to the power terminal 107 of the power connector 100.

[0055] The power terminal 107 has a conductive clip 107a, and when the foolproof slider 304 is in the second position, the second part 304b is inserted into the conductive clip 107a of the power terminal 107, so that the power terminal 107 is electrically connected to the foolproof slider 304.

[0056] It is understood that the end of the second part 304b of the foolproof slider 304 may also be provided with a limiting protrusion structure. The limiting protrusion structure can be configured to cooperate with the conductive clip 107a of the power terminal 107, so that the power terminal 107 is electrically connected to the foolproof slider 304, thereby making the power terminal 107 electrically connected to the cable 200.

[0057] In the above embodiment, the foolproof slider 304 includes a first part 304a and a second part 304b. The first part 304a of the foolproof slider 304 can directly contact the cable 200 to receive the force of the cable 200, thereby pushing the foolproof slider 304 to slide within the insertion hole 101a. A conductive probe 105 is provided on the side of the first part 304a facing the insertion hole 101a, and the conductive probe 105 can make an electrical connection with the cable 200 inserted into the insertion hole 101a. The side of the first part 304a facing away from the insertion hole 101a abuts against the elastic member 307. When the cable 200 is inserted, the first part 304a is subjected to the force applied by the cable 200, which can be transmitted to the elastic member 307, causing the elastic member 307 to undergo elastic deformation. The second part 304b of the foolproof slider 304 extends along the insertion direction F of the cable 200. When the foolproof slider 304 is in different positions, the connection state of the second part 304b with the power terminal 107 of the power connector 100 is different. When the foolproof slider 304 is in the first position, the second part 304b is disconnected from the power terminal 107, thereby cutting off the electrical connection between the cable 200 and the power terminal 107. When the foolproof slider 304 is in the second position, the second part 304b is inserted into the conductive clip 107a of the power terminal 107, realizing the electrical connection between the cable 200 and the power terminal 107. The conductive probe 105 provided on the first part 304a of the foolproof slider 304 is connected to the cable 200, while the second part 304b of the foolproof slider 304 is connected to the conductive clip 107a of the power terminal 107, forming a continuous electrical connection path. This connection method ensures the stability and reliability of the electrical connection. The contact between the conductive probe 105 and the cable 200, and the cooperation between the conductive clamp 107a and the second part 304b, can improve the reliability of conductivity, avoid problems such as local overheating and unstable signal transmission caused by poor connection, and provide a stable power supply for the equipment.

[0058] In some embodiments, referring to Figures 1 and 4, the power connector 100 further includes a retaining mechanism 106 or 406, the retaining mechanism 106 including at least one positioning tooth 106a, the retaining mechanism 406 including at least one positioning tooth 406a, the at least one positioning tooth 106a or 406a being configured to pass through a corresponding hole on the housing 101 when the foolproof slider 104 or 304 (as shown in Figure 3) is in the second position, to secure the cable 200 inserted into the plug hole 101a by deforming the rubber layer of the cable 300 (as shown in Figure 7c).

[0059] In the above embodiments, the power connector 100 further includes a fixing mechanism 106 or 406. The fixing mechanism 106 includes at least one positioning tooth 106a, and the fixing mechanism 406 includes at least one positioning tooth 406a, the positioning teeth 106a or 406a being configured to pass through corresponding holes on the housing 101. When the foolproof slider 104 or 304 is in the second position (i.e., the cable 200 is fully inserted), the fixing mechanism 106 or 406 can secure the cable 200 inserted into the insertion hole 101a via the corresponding positioning teeth 106a or 406a. For example, the positioning teeth 106a or 406a can penetrate the rubber layer of the cable 200, causing local deformation of the rubber layer, thereby firmly fixing the cable 200 inside the power connector 200. Because the power connector 200 includes the fixing mechanism 106 or 406, the operator can complete the installation and fixing of the cable 200 without additional tools, thus simplifying the installation process. The fixing mechanism, combined with the foolproof slider mechanism, ensures that an electrical connection is only formed when the cable 200 is fully inserted and properly secured. If the cable 200 is not locked by the fixing device (such as the positioning teeth), the elastic element 103 or 307 (as shown in Figure 3) will eject the cable 200 due to its own elasticity, further ensuring the safety of the connection. The positioning teeth 106a or 406a ensure that the cable 200 is secured once inserted, reducing the risk of the cable 200 loosening or falling off due to vibration or other external factors. This mechanical fixing method improves the reliability and stability of the entire system.

[0060] In some embodiments, referring to Figures 1 and 4, the fixing mechanism 106 includes a pressure plate 106b, and the fixing mechanism 406 further includes a pressure plate 406b, with at least one positioning tooth 106a or 406a correspondingly disposed on the pressure plate 106b or 406b, and the pressure plate 106b or 406b configured to be connected to the housing 101 via a corresponding pivot 106c or 406c. It is understood that the positions of the pressure plate 106b or 406b and the pivot 106c or 406c can be either away from or near the opening end of the insertion hole 101a. As shown in Figure 1, the pivot is located near the opening end of the insertion hole 101a, a configuration that further prevents the cable 200 from accidentally coming loose during operation. As shown in Figure 4, the pivot is located away from the opening end of the insertion hole 101a, a configuration that facilitates further clamping of the cable 200. However, to prevent the cable 200 from coming loose along with the positioning tooth, additional fastening structures may be needed to enhance the fixing effect. These two different pivot position designs can be selected according to the needs of the application scenario.

[0061] In the above embodiments, the fixing mechanism 106 further includes a pressure plate 106b, and the fixing mechanism 406 further includes a pressure plate 406b. The pressure plate 106b or 406b is capable of bearing and transmitting the force used to fasten the cable 200. The pressure plate 106b or 406b is connected to the housing 101 via a corresponding pivot 106c or 406c, and at least one positioning tooth 106a or 406a is provided on the corresponding pressure plate 106b or 406b, such that at least one positioning tooth 106a or 406a moves with the movement of the pressure plate about the pivot. When the pressure plate 106b or 406b is fully flush against the housing 101, the corresponding positioning teeth 106a or 406a pass through the corresponding holes on the housing 101 to secure the cable 200 inside the power connector 100 (as shown in Figure 7c). When the pressure plate 106b or 406b (except for the portion in contact with the pivot) is as far away from the housing 101 as possible, the corresponding positioning teeth 106a or 406a also move away from the cable 200, allowing the cable 200 to be removed or adjusted. The engagement of the positioning teeth 106a or 406a with the corresponding pressure plate 106b or 406b makes the operation of securing the cable 200 simpler and more reliable.

[0062] In some embodiments, referring to Figures 1 and 5, the power connector 100 includes a fixing mechanism 506, the fixing mechanism 506 comprising: a button 506a, at least one positioning tooth disposed on the side of the button 506a facing the housing 101; a spring 506b disposed between the button 506a and the housing 101; and a locking device 506c configured to lock the at least one positioning tooth when the at least one positioning tooth secures the cable 200 inserted into the insertion hole 101a.

[0063] In the above embodiments, the fixing mechanism 506 includes a button 506a, a spring 506b, and a locking device 506c. The button 506a can be located outside the power connector 100, and the operator can trigger the operation of fastening the cable 200 using the button 506a. Specifically, the button 506a can transmit the force applied by the operator pressing the button 506a to the positioning teeth, thereby fastening the cable 200. Here, the positioning teeth can be similar to or the same as the positioning teeth 106a or 406a in the above embodiments. The spring 506b is located between the button 506a and the housing 101. The spring 506b provides elasticity. When the user presses the button 506a, the spring 506b is compressed. The locking device 506c is used to lock the button 506a after it is fully pressed, thereby locking the position and state of the positioning teeth. The locking device 506c can automatically lock the button 506a while the positioning teeth are fastening the cable 200, preventing the button 506a from accidentally loosening or springing up. The locking device 506c can achieve the locking function through a snap, latch, or other mechanical structure, thereby ensuring that the positioning teeth remain in the state of securing the cable 200. If it is necessary to remove or adjust the cable 200, the operator can press the button 506a again to release the locking state of the button 506a. Once the button 506a is released, the elasticity of the spring 506b will push the button 506a back to its initial position, causing the positioning teeth to disengage from the cable 200, thus allowing the cable 200 to be removed or reinserted. With the fixing mechanism 506 including the button 506a, spring 506b, and locking device 506c, the operator only needs to insert the cable 200 into the bottom of the insertion hole 101a and then press the button 506a to secure the cable 200 without additional tools. Similarly, to remove the cable 200, press the button 506a again to release the cable 200. This method not only simplifies the installation steps of the cable 200, but also reduces the skill requirements of the construction personnel and improves work efficiency.

[0064] It is understood that the power terminals 107 of the power connector 100 are not limited to being positioned along the insertion direction F of the cable 200. For example, referring to Figures 1 and 5, the power terminals 107 can be positioned in a direction substantially perpendicular to the insertion direction F of the cable 200 to accommodate the needs of different application scenarios. This design flexibility allows the power connector 100 to better meet diverse installation requirements. In some embodiments, referring to Figures 1 and 6, portions of the housing 101 can be removed. Specifically, without affecting the operation of the foolproof slider, elastic element, and fixing mechanism, as well as the normal insertion of the cable, some portions of the housing 101 can be removed, making the power connector 100 more compact and saving materials. Such a design not only optimizes space utilization but also allows the shape of the power connector 100 to be customized to suit specific application environments.
