Description
Technical Field
[0001] This utility model relates to the field of track socket technology, and more specifically, to a safety track socket and adapter. Background Technology
[0002] A track socket typically includes an adapter and a long, narrow power track. The adapter's contacts are inserted into slots in the power track and make contact with conductive plates inside the power track to draw power.

This necessitates a complex, interconnected mechanical structure between the adapter and the rail. Furthermore, existing power rails have an open design, and as the energized side, foreign objects inserted into the rails can easily come into contact with the conductive plates, creating a risk of leakage and compromising safety.

[0016] In an optional embodiment, the guide arm insert has a supporting protrusion on the side near the adapter body, the supporting protrusion protruding toward the adapter body, and the electrical contact protruding on the supporting protrusion.
[0017] In an optional embodiment, the front of the adapter body is provided with an insertion hole, and the back of the adapter body is partially raised to provide a mounting base. The guide arm insert is disposed on the mounting base and suspended on the back of the adapter body.

[0020] The beneficial effects of this utility model embodiment include:
[0021] The safety track socket provided in this embodiment of the utility model has a guide arm insert disposed on one side of the adapter body, and an accommodating gap is formed between the guide arm insert and the adapter body. An electrical contact is protruding from the side of the guide arm insert near the adapter body.

A stop protrusion is also provided on the base near the bottom of the slot, which can abut against the guide arm insert, allowing the electrical contacts on the guide arm insert to make electrical contact with the conductive sheet. Compared to existing technologies, the safety track socket provided in this embodiment of the invention can, on the one hand, conceal the conductive sheet by protruding the slot. When a foreign object (such as a conductive strip) is inserted into the power slot, the protrusion pushes the object away from the conductive sheet, preventing it from contacting the conductive sheet and thus reducing the risk of leakage from foreign object insertion, thereby improving safety. On the other hand, the electrical contacts on the adapter are protruding structures, eliminating the need for additional pop-out designs. The electrical contacts can be pushed against the conductive sheet by the resisting action of the protrusion, resulting in a simple and reliable structure. No linkage mechanical structure is required; it can be directly plugged in and out, making it convenient and reliable. Attached Figure Description

Detailed Implementation
[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0041] See Figures 1 to 3 This utility model provides a safety track socket 100, which has a simple and reliable structure, requires no linkage mechanical structure, and can be directly plugged in and unplugged, making it convenient and reliable. At the same time, it can conceal the conductive structure inside the track, reducing the risk of leakage from foreign objects and improving safety.
[0042] This utility model embodiment provides a safety rail socket 100, including an adapter 110 and a power rail base 140 that cooperate with each other. The adapter 110 can be one or more, and each adapter 110 includes an adapter body 120 and a guide arm insert 130. The guide arm insert 130 is disposed on one side of the adapter body 120, and a receiving gap 131 is formed between the guide arm insert 130 and the adapter body 120. An electrical contact 132 protrudes from the side of the guide arm insert 130 near the adapter body 120. The power rail base 140 includes a base 150 and an electrical conductor plate 160 disposed on one side of the base 150. A space for the guide arm insert 130 is formed between the electrical conductor plate 160 and the base 150. The electrical slot 161 is inserted into a base 150. A conductive plate 162 is provided on the side of the electrical conductive plate 160 near the base 150. A slot protrusion 170 is provided at one end of the electrical conductive plate 160 near the slot opening of the electrical slot 161, protruding towards the base 150. The slot protrusion 170 is configured to block the conductive plate 162 in the insertion direction of the guide arm insert 130 and prevent any external component inserted into the electrical slot 161 from approaching the conductive plate 162. A stop protrusion 151 is also provided on the side wall of the base 150 near the bottom of the slot of the electrical slot 161, protruding towards the electrical conductive plate 160. The stop protrusion 151 is configured to abut against the guide arm insert 130, so that the electrical contact 132 makes electrical contact with the conductive plate 162. The external component can be a conductive wire accidentally inserted into the electrical slot 161 or other components that may cause an electric shock risk.
[0043] In practical use, the guide arm insert 130 of the adapter 110 can be inserted into the power slot 161. Under the resistance of the stop protrusion 151, the end of the guide arm insert 130 will bend towards the conductive sheet 162, so that the electrical contact 132 makes electrical contact with the conductive sheet 162, thus achieving electrical connection. Moreover, since the electrical contact 132 on the adapter 110 is a raised structure, there is no need to design an additional pop-out structure. The electrical contact 132 can be supported by the stop protrusion 151, which narrows the bottom width of the power slot 161 and pushes the electrical contact 132 against the conductive sheet 162. The structure is simple and reliable, without the need for a linkage mechanical structure, and can be directly plugged in and out, which is convenient and reliable. In the area where the adapter 110 is not inserted, the slot protrusion 170 makes the slot width narrower than the inner middle part. Therefore, the slot protrusion 170 can cover the conductive sheet 162, thus hiding the conductive sheet 162 and reducing the risk of foreign objects falling into the slot. Furthermore, even if an external component (such as a conductive strip) extends into the power slot 161, the slot protrusion 170 can push the foreign object away from the conductive sheet 162, preventing it from contacting the conductive sheet 162, thereby reducing the risk of leakage due to foreign object insertion and improving safety.
[0044] It is worth noting that the base 150 can be attached to a wall or other supporting surface, and the electrical conductor 160 can be integrally mounted on the side of the base 150 away from the wall, forming an upward-opening electrical slot 161. The guide arm insert 130 can be inserted into the electrical slot 161 from top to bottom. Of course, the attachment direction of the base 150 can also be changed so that the opening direction of the electrical slot 161 is horizontally to the left or horizontally to the right. In this case, the guide arm insert 130 can be inserted into the electrical slot 161 in a horizontal left-right direction.
[0045] See Figures 2 to 5 In some embodiments, the electrical conductive plate 160 is further provided with a receiving groove 163 on the side near the base 150. A conductive sheet 162 is disposed within the receiving groove 163, and an electrical contact 132 is configured to extend into the receiving groove 163 and make electrical contact with the conductive sheet 162. Specifically, the opening of the receiving groove 163 faces the base 150, allowing the receiving groove 163 to be recessed away from the base 150. The conductive sheet 162 can be a copper sheet and is embedded within the receiving groove 163. By providing the receiving groove 163, the conductive sheet 162 can be fixedly embedded, and the conductive sheet 162 can be further concealed, minimizing contact between external conductive foreign objects and the conductive sheet 162. The electrical contact 132, supported by the stop protrusion 151, extends into the receiving groove 163 and electrically abuts against the conductive sheet 162, ensuring effective electrical connection.
[0046] In some embodiments, there are two conductive sheets 162, two receiving grooves 163, and two electrical contacts 132. The two conductive sheets 162 are respectively configured to connect to the live wire and the neutral wire. The two receiving grooves 163 are arranged parallel to each other on the sidewall of the electrical conductive plate 160. The two conductive sheets 162 are respectively disposed in the two receiving grooves 163, and the two electrical contacts 132 respectively abut against the two conductive sheets 162. Specifically, the two electrical contacts 132 can be designed to be staggered in the horizontal direction, so that the two electrical contacts 132 can abut against the two conductive sheets 162 in a staggered manner, thereby minimizing interference between the two electrical contacts 132 when they abut against each other.
[0047] In some embodiments, a grounding plate 164 is further provided within the power slot 161, and a grounding contact 133 is provided at the end of the guide arm insert 130, the grounding contact 133 being configured to contact the grounding plate 164. Specifically, the free end of the guide arm insert 130 is provided with the grounding contact 133, and when the guide arm insert 130 is inserted into the power slot 161, the grounding contact 133 makes electrical contact with the grounding plate 164, thereby achieving grounding.
[0048] Furthermore, the grounding plate 164 has a clamping groove 165, and the grounding contact 133 is plate-shaped and protrudes relative to the end of the guide arm insert 130. The grounding contact 133 is configured to be inserted into the clamping groove 165. Specifically, the clamping groove 165 has a funnel-shaped opening that is larger on the outside and smaller on the inside, which facilitates the insertion of the grounding contact 133. The grounding plate 164 can be fixedly mounted on the bottom wall of the power slot 161, and the opening of the clamping groove 165 faces upward to ensure the grounding effect.
[0049] In some embodiments, the stop protrusion 151 is further provided with a first guide slope 152. The first guide slope 152 extends from the side wall of the base 150 toward the electrical conductive plate 160 and is inclined toward the insertion direction of the guide arm insert 130. Specifically, the first guide slope 152 extends inclined toward the bottom wall of the power slot 161. When the guide arm insert 130 is inserted, its free end can first contact the first guide slope 152 and continue to slide downward under the guidance of the first guide slope 152, and move toward the conductive sheet 162. At the end of the first guide slope 152, the stop protrusion 151 can abut against the surface of the guide arm insert 130, thereby ensuring that the electrical contact 132 can make electrical contact with the conductive sheet 162.
[0050] It should be noted that, in order to prevent the guide arm insert 130 from jamming, the stop protrusion 151 can have a certain degree of elasticity. Specifically, the bottom end of the stop protrusion 151 can be separated from the base 150, so that the stop protrusion 151 has a spring-like structure, which can provide a certain elastic margin to ensure that it is held against the guide arm insert 130. On the one hand, this can prevent the guide arm insert 130 from jamming, and on the other hand, it can prevent the electrical contacts 132 from being damaged or difficult to insert or remove due to excessive pressure.
[0051] In some embodiments, the electrical conductive plate 160 is inserted into the receiving gap 131. The side of the electrical conductive plate 160 away from the base 150 is also provided with an outer edge protrusion 166, which is configured to abut against the surface of the adapter body 120 near the guide arm insert 130. Specifically, the outer edge protrusion 166 abuts against a position on the adapter body 120 corresponding to the free end of the guide arm insert 130, thereby ensuring that the electrical conductive plate 160 can be inserted into the receiving gap 131 for fixation.
[0052] Furthermore, a second guide slope 167 is provided on the outer edge protrusion 166. The second guide slope 167 extends from the side wall of the electrical conductive plate 160 in a direction away from the base 150 and is inclined towards the insertion direction of the guide arm insert 130. Specifically, during the process of inserting the guide arm insert 130 into the power slot 161, the bottom end of the adapter body (the position corresponding to the free end of the guide arm insert 130) can precisely abut against the second guide slope 167 and slide into place along the second guide slope 167. After being assembled in place, the adapter body can abut against the surface of the outer edge protrusion 166.
[0053] See Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 In some embodiments, the guide arm insert 130 has a supporting protrusion 134 on the side near the adapter body 120. The supporting protrusion 134 protrudes towards the adapter body 120, and an electrical contact 132 protrudes from the supporting protrusion 134. Specifically, the supporting protrusion 134 is integrally formed at the free end of the guide arm insert 130 and protrudes towards the adapter body 120. The electrical contact 132 is embedded in the supporting protrusion 134 and extends out of the supporting protrusion 134. The electrical contact 132 can be connected to the electrical connection structure in the adapter body 120 through internal conductive lines. The electrical contact 132 can be an elastic contact that always remains in an outwardly ejected state and can retract during insertion into the power slot 161, thereby making the slot as narrow as possible. By providing the supporting protrusion 134, the contact position of the electrical contact 132 can be closer to the conductive sheet 162, which is beneficial for the electrical contact 132 to make contact with the conductive sheet 162. Meanwhile, a clearance groove is formed between the supporting protrusion 134 and the root of the guide arm insert 130, which can just avoid the groove protrusion 170.
[0054] In some embodiments, the front of the adapter body 120 is provided with a socket 121, and the back of the adapter body 120 is partially raised with a mounting base 122. A guide arm insert 130 is disposed on the mounting base 122 and suspended on the back of the adapter body 120. Specifically, a conductive sleeve is provided in the socket 121, which can be connected to an electrical contact 132. Its specific structure can be referred to as an existing socket. The mounting base 122 is integrally disposed on one side edge of the back of the adapter body 120. One end of the guide arm insert 130 is connected to the mounting base 122, and the other end extends toward the other side edge of the mounting base 122 and is suspended in a cantilever shape on the back of the adapter body 120.
[0055] It should be noted that in this embodiment, the abutment protrusion 134 is trapezoidal, and the width of the abutment protrusion 134 gradually decreases along the protrusion direction. Here, the width refers to the width of the abutment protrusion 134 in the extension direction of the guide arm insert 130. The abutment protrusion 134 has a sloping surface on both the side near the mounting base 122 and the side away from the mounting base 122. During the insertion of the guide arm insert 130, the side of the abutment protrusion 134 away from the mounting base 122 can first abut against the upper edge of the slot protrusion 170. Under the guidance of this sloping surface, the abutment protrusion 134 is smoothly inserted into the power slot 161. Similarly, during the removal of the guide arm insert 130, the side of the abutment protrusion 134 near the mounting base 122 can also abut against the lower edge of the slot protrusion 170. Under the guidance of this sloping surface, the abutment protrusion 134 can be smoothly removed from the power slot 161.
[0056] In some embodiments, the sides of the adapter body are also provided with anti-slip textures, which are located on the left and right sides of the adapter body to facilitate gripping.
[0057] In some embodiments, the back of the adapter body 120 is further provided with a main body protrusion 123, which protrudes toward the guide arm insert 130 and is connected to the mounting base 122, configured to abut against the side surface of the electrical conductor plate 160 away from the base 150. Specifically, the main body protrusion 123 can reduce the width of the receiving gap 131. By providing the main body protrusion 123, it can abut against the electrical conductor plate 160, ensuring that the electrical conductor plate 160 is tightly fitted within the receiving gap 131, ensuring a secure assembly. Furthermore, the main body protrusion can also limit the adapter body 120 in the horizontal direction, allowing the adapter 110 to be fixed on the power rail.
[0058] Furthermore, one side of the main body protrusion 123 is connected to the mounting base 122, and the other side is inclined. This inclined surface can abut against the top edge of the electrical conductor 160, making it convenient for the electrical conductor 160 to be inserted into the receiving gap 131.
[0059] It should be noted that in some embodiments, the width of the guide arm insert 130 along the extension direction of the power slot 161 is smaller than the width of the mounting base 122, which allows the guide arm insert 130 to be inserted into the power slot 161 more easily and is convenient to insert and remove.
[0060] The safety track socket 100 provided in this embodiment of the utility model has the following working process:
[0061] First, fix the base 150 of the power rail to the wall, ensuring the opening of the power slot 161 faces upwards. Then, bring the adapter 110 close to the power rail, first fitting the mounting base 122 of the adapter 110 against the upper surface of the base 150, and then move the adapter 110 downwards. The thickness of the abutment protrusion on the guide arm insert 130 of the adapter 110 is slightly less than the width of the slot, allowing the guide arm insert 130 of the adapter 110 to insert downwards into the power slot 161. The electrical contact 132 can be squeezed and spring back inwards, thus allowing the guide arm insert 130 to smoothly insert into the slot, while making the slot as narrow as possible. After the guide arm insert 130 is inserted into the power slot 161, it is fully inserted under the combined guidance of the internal stop protrusion 151, the external outer edge protrusion 166, and the main body protrusion 123 on the adapter 110. The electrical contact 132 on the adapter 110 makes contact with the conductive piece 162, and the adapter 110 is powered on and begins operation. Meanwhile, the adapter 110 remains fixed, restricting its free movement. When it needs to be unplugged, simply lift the adapter 110 upwards, which is very convenient.
[0062] See Figure 7 and Figure 9 This utility model embodiment also provides an adapter 110, which is applicable to the aforementioned safety rail socket 100. Further, the adapter 110 includes an adapter body 120 and a guide arm insert 130. The guide arm insert 130 is disposed on one side of the adapter body 120, and a receiving gap 131 is formed between the guide arm insert 130 and the adapter body 120. An electrical contact 132 is protruding on the side of the guide arm insert 130 near the adapter body 120.
[0063] Furthermore, the front of the adapter body 120 is provided with a socket 121 for inserting a load-side plug, and the adapter body 120 is provided with a socket module 124, a current detection device 125, a sensing radar 126 and a power-off control device 127.
[0064] The socket module 124 corresponds to the socket 121 and is configured to connect to the load-side plug; the current detection device 125 is connected to the socket module 124 and is configured to detect the current value of the socket module 124; the sensing radar 126 is located near the front of the adapter body 120 and is configured to detect the obstruction signal on the front of the adapter body 120; the power-off control device 127 is connected to the socket module 124 and is also communicatively connected to the current detection device 125 and the sensing radar 126, and is configured to control the power-on and power-off status of the socket module 124; wherein, the power-off control device 127 is configured to control the socket module 124 to power off when the current value is less than a preset value and the sensing radar 126 detects an obstruction signal.
[0065] It should be noted that the preset value here can be the standby current value of the load. In this embodiment, a socket 121 is provided on the front of the adapter body 120, and the adapter body 120 is provided with a socket module 124, a current detection device 125, a sensing radar 126, and a power-off control device 127. The socket module 124 corresponds to the socket, so that it can be connected to the load-side plug inserted into the socket. The current detection device 125 can detect the current value of the socket module 124, thereby providing a basis for judging whether the load appliance is working normally. When the current value is greater than the preset value, it means that the load appliance is working normally, and the power-off action will not be triggered. When the current value is less than or equal to the preset value, it means that the load appliance is not working or is only in a standby state. In this case, the power-off action can be triggered in combination with the obstruction situation, which is safe and reliable. The sensing radar 126 is close to the front of the adapter body 120 and can detect obstruction signals. The power-off control device 127 can control the plug module 124 to cut off power when the current value of the plug module 124 is low (less than the preset value) and the front of the adapter body 120 is obstructed, thereby achieving safety protection for the adapter 110. Therefore, this utility model embodiment uses the sensing radar 126 to determine the approaching object, which is more accurate and reliable than heat source detection. The additionally designed current detection device 125 can detect the current signal value and determine whether a load appliance is in use. When no load appliance is in normal use and a child, pet or other object is close to the adapter 110, the power-off control device 127 can cut off the power, which can effectively avoid the risk of electric shock caused by children accidentally touching the switch. At the same time, the power-off should be performed when the load appliance is not in use, which can also avoid accidental power-off when in use, thus protecting electrical safety without affecting the user experience. In some preferred embodiments, the power-off control device 127 includes a relay that is communicatively connected to both the sensing radar 126 and the current detection device 125. The relay is configured to disconnect when the current detection device 125 detects a current value less than or equal to 5mA and the sensing radar 126 detects an obstruction signal, thereby de-energizing the socket module 124. The relay is also configured to shield the sensing radar 126 and energize it when the current detection device 125 detects a current value greater than 5mA, thereby energizing the socket module 124. The preset current value is 5mA, which is the standby current value. When the current value is greater than this preset value, the surface load operates normally; when it is less than or equal to this preset value, the surface load is not operating or is in standby mode, and power-off in this case will not affect the load.
[0066] In some preferred embodiments, the adapter body 120 is further provided with a rectifier, which is connected to the current detection device 125 and configured to supply DC power to the current detection device 125. Specifically, the rectifier can use a rectifier bridge circuit to step down the voltage, switching the V AC power to V DC power to supply the current detection device 125, thereby realizing DC power supply to the current detection device 125.
[0067] See Figure 10 The control principle of the safety sensor adapter 110 is described in detail below. First, 220V AC power is stepped down by the rectifier and then supplied to the current detection device 125 via a rectifier bridge. The current detection device 125 can detect whether there is current in the socket module 124, that is, detect the current value of the socket module 124. When a normal current value is detected in the socket module 124, it indicates that the load appliance is in a working energized state. At this time, the relay is continuously energized, thereby controlling the socket module 124 to be in an energized state, realizing the power supply of the load appliance. When the socket module 124 detects no current or a low current value, it indicates that the load device is in a non-working, power-off, or standby state. At this time, it is necessary to further detect the obstruction signal on the front of the adapter housing through the sensing radar 126. When there is obstruction on the front of the adapter housing (i.e., obstruction signal is detected), it indicates a risk of electric shock. At this time, the relay is disconnected, thereby controlling the socket module 124 to be in a power-off state to avoid electric shock. When there is no obstruction on the front of the adapter housing (i.e., no obstruction signal is detected), it indicates no risk of electric shock. At this time, the relay remains energized to power on the load device.
[0068] In summary, the safety track socket 100 provided in this embodiment of the present invention has a guide arm insert 130 disposed on one side of the adapter body 120, and a receiving gap 131 is formed between the guide arm insert 130 and the adapter body 120. An electrical contact 132 protrudes from the side of the guide arm insert 130 near the adapter body 120. Simultaneously, an electrical guide plate 160 is disposed on some parts of the base 150, and a power slot 161 for inserting the guide arm insert 130 is formed between the electrical guide plate 160 and the base 150. A conductive sheet 162 is also disposed on the side of the electrical guide plate 160 near the base 150. Furthermore, a slot protrusion 170 is provided on the electrical guide plate 160 near the slot opening, which can cover the conductive sheet 162, thereby concealing the conductive sheet 162 inside the power slot 161. The base 150 is also provided with a stop protrusion 151 near the bottom of the slot. The stop protrusion 151 can abut against the guide arm insert 130, so that the electrical contact 132 on the guide arm insert 130 can make electrical contact with the conductive sheet 162. Compared with the prior art, the safety track socket 100 provided by this utility model embodiment can, on the one hand, cover the conductive sheet 162 with the slot protrusion 170, thereby hiding the conductive sheet 162. When a foreign object (such as a conductive strip) is inserted into the power slot 161, the slot protrusion 170 can push the foreign object away from the conductive sheet 162, preventing it from contacting the conductive sheet 162, thereby reducing the risk of leakage due to foreign object insertion and improving safety. On the other hand, the electrical contacts 132 on the adapter 110 are elastic protrusion structures, eliminating the need for additional pop-out structures. The electrical contacts 132 can be pushed against the conductive sheet 162 by the abutment action of the stop protrusion 151. The structure is simple and reliable, requiring no linkage mechanical structure, and can be directly plugged in and out, making it convenient and reliable.
[0069] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
