Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and more particularly to a socket, socket assembly and receptacle. Background Technology

[0002] In the widespread application of modern electrical equipment, sockets play a crucial role as a key component for power transmission. They serve as a bridge connecting electronic devices to the power source, and the stability and reliability of their structure are essential for ensuring the normal operation of the equipment and extending its service life. A socket includes a socket sleeve. When an electronic device is connected to the socket, specifically, the pins of the electronic device are electrically connected to the socket sleeve, allowing the electronic device to receive electrical energy from the power source.

[0003] However, in the relevant technology, the design of the socket sleeve is not reasonable enough. When inserting or removing the plug from the socket, the required insertion and extraction force is not stable enough, which affects the user's experience when inserting or removing the plug. Utility Model Content

[0004] This application provides a socket, a socket assembly, and a socket, which can make the insertion and extraction force more stable, thereby improving the user experience when using the socket.

[0005] In a first aspect, this application provides a sleeve for engaging with a pin. The sleeve has intersecting first and second directions, and the pin can be inserted into and removed from the sleeve along the first direction. The sleeve includes a sleeve body, a first clamping arm, and a second clamping arm. The first clamping arm and the second clamping arm are disposed opposite each other on the same side of the sleeve body along the second direction in the first direction. When a pin is inserted into the sleeve, a portion of the pin is clamped in the first clamping arm and the second clamping arm.

[0006] The first clamping arm and / or the second clamping arm includes a first sub-arm and a second sub-arm connected to each other. The first sub-arm is connected to the socket body and protrudes from the socket body in a first direction. In a second direction, the projection of the first clamping arm coincides with the projection of the second clamping arm. During the insertion of the pin into the socket, both the first and second sub-arms can deform with the insertion and removal of the pin.

[0007] In this application, when the pin is inserted into or removed from the socket, the first clamping arm and / or the second clamping arm can undergo two-stage deformation. This results in a gradual change in the insertion and removal force, reducing the possibility of unstable force fluctuations and making the user experience smoother when inserting or removing the pin, thus improving the user's experience when using the socket.

[0008] Optionally, there is an insertion space between the first clamping arm and the second clamping arm, and the insertion sleeve also includes an anti-bend arm. The anti-bend arm is connected to the second sub-arm and extends in a direction away from the insertion space.

[0009] In this way, the anti-folding arm can reduce the possibility of excessive deformation of the first and second clamping arms. Furthermore, it can reduce the possibility that burrs or other defects on the anti-folding arm might snag the pin when it is pulled out of the socket, making it difficult to remove the pin from the insertion space and affecting the user experience.

[0010] The optional first sub-arm is also provided with a first adjustment hole, which extends through the first sub-arm along the second direction.

[0011] The above solution can improve the elasticity of the first sub-arm, reduce the force required to insert and remove the pin from the socket, and improve the smoothness of pin insertion.

[0012] Optionally, a second adjustment hole is provided on the second sub-arm, and the second adjustment hole extends through the second sub-arm along a second direction.

[0013] The above solution can improve the elasticity of the second sub-arm, reduce the force required to insert and remove the pin from the socket, and improve the smoothness of pin insertion.

[0014] Optionally, in the second direction, the socket body has a first side arm and a second side arm, with a first clamping arm connected to the first side arm and a second clamping arm connected to the second side arm. When the first clamping arm includes a first sub-arm and a second sub-arm, the side of the first sub-arm facing away from the second clamping arm is a first plane, and the first plane has a first included angle α with the first side arm, satisfying: 5°≤α≤25°.

[0015] In the case where the second clamping arm includes a first sub-arm and a second sub-arm, the side of the first sub-arm away from the first clamping arm is a second plane, and there is a second included angle β between the second plane and the second side arm, which satisfies: 5°≤β≤25°.

[0016] In this application, the first sub-arm is inclined. Thus, when the pin is inserted into or removed from the sleeve and the pin presses against the sleeve, the inclined first sub-arm can provide a deformation tendency for the first sub-arm, which is beneficial to the rotation and deformation of the first sub-arm.

[0017] Optionally, when the first clamping arm includes a first sub-arm and a second sub-arm, the side of the first sub-arm facing away from the second clamping arm is a first arc surface. When the second clamping arm includes a first sub-arm and a second sub-arm, the side of the first sub-arm facing away from the first clamping arm is a second arc surface.

[0018] This design allows the side of the first sub-arm that faces away from the second clamping arm to be more smoothly rounded. This also ensures that when the first sub-arm is under stress, the force is distributed more evenly across it. Furthermore, the curved design facilitates the deformation of the first sub-arm, reducing localized stress concentration and the likelihood of damage.

[0019] Secondly, this application provides a socket assembly, including a connecting strip and a plurality of sockets as described in the first aspect above, wherein the plurality of sockets are connected to the connecting strip at intervals.

[0020] Thirdly, this application provides a socket including the socket assembly described in the second aspect above.

[0021] Optionally, the socket also includes a housing, a socket assembly is mounted on the housing, the housing is provided with multiple mounting slots, and multiple sockets are embedded in the mounting slots one by one. In the second direction, the mounting slots have opposing first slot walls and second slot walls.

[0022] A first support boss is connected to the side of the insert body facing the first groove wall, and the first support boss mates with the first groove wall. And / or, a second support boss is connected to the side of the insert body facing the second groove wall, and the second support boss mates with the second groove wall.

[0023] Optionally, when a first support boss is connected to the socket body, the first support boss has a first dimension L1 in the second direction, wherein the first dimension L1 satisfies: 0 < L1 ≤ 0.4 mm. When a second support boss is connected to the socket body, the second support boss has a second dimension L2 in the second direction, wherein the second dimension L2 satisfies: 0 < L2 ≤ 0.4 mm.

[0024] The beneficial effects of the socket assembly provided in the second aspect and the various possible designs of the second aspect, and the socket provided in the third aspect and the various possible designs of the third aspect, can be found in the beneficial effects of the first aspect and the various possible embodiments of the first aspect, and will not be repeated here.

[0042] Reference Figure 1 and Figure 2 As shown, this application provides a sleeve 100 for engaging with a pin. The sleeve 100 has intersecting first direction X and second direction Y, and the pin can be inserted and removed from the sleeve 100 along the first direction X. The sleeve 100 includes a sleeve body 110, a first clamping arm 120, and a second clamping arm 130. The first clamping arm 120 and the second clamping arm 130 are disposed opposite each other on the same side of the sleeve body 110 along the second direction Y in the first direction X. When a pin is inserted into the sleeve 100, part of the pin is clamped in the first clamping arm 120 and the second clamping arm 130.

[0043] The first clamping arm 120 and / or the second clamping arm 130 include a first sub-arm 10 and a second sub-arm 20. The first sub-arm 10 is connected to the socket body 110 and protrudes from the socket body 110 along the first direction X. The second sub-arm 20 is connected to the end of the first sub-arm 10 away from the socket body 110. In the second direction Y, the projections of the first clamping arm 120 and the second clamping arm 130 coincide. During the insertion of the pin into the socket 100, both the first sub-arm 10 and the second sub-arm 20 can deform as the pin is inserted or removed.

[0044] In this embodiment, the first clamping arm 120 and the second clamping arm 130 are both connected to the insert body 110. The insert body 110, the first clamping arm 120 and the second clamping arm 130 can cooperate to realize the electrical connection between the insert 100 and the pin.

[0045] Specifically, the first clamping arm 120 and the second clamping arm 130 are connected to the same side of the socket 100, and are arranged opposite to each other. Therefore, when a pin is inserted into the socket 100, the first clamping arm 120 and the second clamping arm 130 can clamp the pin from opposite sides. In this way, both sides of the pin are subjected to force, which can form a stable contact pressure between the socket 100 and the pin, facilitating the transfer of electrical energy between the socket 100 and the pin.

[0046] In this application, the first clamping arm 120 and / or the second clamping arm 130 may include a first sub-arm 10 and a second sub-arm 20. The first sub-arm 10 protrudes from the socket body 110 along a first direction X, thus extending in a direction away from the socket body 110. In the second direction Y, the projections of the first clamping arm 120 and the second clamping arm 130 coincide; therefore, the second sub-arm 20 extends in a direction different from the extending direction of the first sub-arm 10.

[0047] Specifically, the first sub-arm 10 has a first end connected to the socket body 110 and a second end connected to the second sub-arm 20. The second sub-arm 20 has a third end connected to the first sub-arm 10 and a fourth end. Here, the socket 100 is used as an example. Figure 2 Taking the orientation shown as an example, the first sub-arm 10 extends upwards in the direction from the first end to the second end, while the second sub-arm 20 extends downwards in the direction from the third end to the fourth end. In this way, the first sub-arm 10 and the second sub-arm 20 can form an arch-like structure.

[0048] In this application, both the first sub-arm 10 and the second sub-arm 20 are deformable, so that during the process of inserting and removing the pin from the socket 100, both the first sub-arm 10 and the second sub-arm 20 can deform as the pin is inserted.

[0049] Combination Figure 2 When the pin is inserted into or removed from the sleeve 100, the second sub-arm 20 directly contacts the pin. The part of the second sub-arm 20 in contact with the pin can cause the rest of the second sub-arm 20 to deform. At the same time, the second sub-arm 20 can also transmit the force of the pin to the first sub-arm 10, causing the first sub-arm 10 to also deform. During this process, the first sub-arm 10 and the second sub-arm 20 as a whole can rotate and deform around the first end of the first sub-arm 10, while the second sub-arm 20 can rotate and deform around the second end of the first sub-arm 10.

[0050] As can be seen, in this application, the first clamping arm 120 and / or the second clamping arm 130 can adopt a design similar to an arched structure, so that when the pin is inserted or removed from the socket 100, the first clamping arm 120 and / or the second clamping arm 130 can undergo two-stage deformation. Specifically, in the initial stage of insertion or removal, the second sub-arm 20 can deform first, and the insertion / removal force gradually increases with the increase of the insertion / removal depth. In the subsequent stage of insertion or removal, the first clamping arm 120 and the second clamping arm 130 bear a larger force, and the second sub-arm 20 will transfer the force to the first sub-arm 10, causing the first sub-arm 10 to also deform.

[0051] In summary, during the insertion and removal of the plug from the socket 100, the number of the first clamping arm 120 and / or the second clamping arm 130 involved in deformation gradually increases. This results in a gradual transmission and accumulation of internal stress within the first clamping arm 120 and / or the second clamping arm 130. Therefore, the insertion and removal force during the plug insertion and removal process does not increase suddenly, but rather exhibits a gradual change. This reduces the possibility of unstable sudden increases and decreases in insertion and removal force, resulting in a smoother feel for the user when inserting and removing the plug, thereby improving the user experience when using the socket.

[0052] In order to make the solution and beneficial effects of this application clearer, this application will be described in detail in conjunction with relevant technologies.

[0053] In related technologies, the socket includes a body and two elastic arms, which are connected to the same side of the body and arranged opposite to each other. When the pin is inserted into the socket 100, the pin can extend between the two elastic arms. The elastic arms are semi-parabolic in shape, and all parts extend in the same direction, towards the interior of the body.

[0054] In this type of socket design in related technologies, the elastic arm rotates and deforms only around its connection point with the main body. During the insertion and removal of the pin, the pin can apply force to its surface through the elastic arm. The line of action of this force is located at the contact point between the elastic arm and the pin, extending along the insertion direction of the pin. The lever arm is the perpendicular distance between the connection point of the elastic arm and the main body, and the line of action of the force. In this design, the lever arm of the elastic element is insufficient, which limits the deformation of the elastic arm to some extent, resulting in a relatively harsh insertion and removal force. Furthermore, the single-segment deformation of the elastic arm makes the deformation mechanism of the socket singular, leading to stress concentration effects. This can cause abrupt changes in insertion and removal force, further complicating the process and reducing the user experience.

[0055] In this embodiment, the first clamping arm 120 and / or the second clamping arm 130 can be segmented and deformable. This allows for a gradual change in the insertion and extraction force during the insertion and extraction process, reducing the possibility of unstable force fluctuations. Furthermore, the arrangement of the first sub-arm 10 and the second sub-arm 20 in this application optimizes the lever arm during the insertion and extraction process. In this case, the line of action of the force is located at the contact position between the pin and the sleeve 100, extending along the first direction X. The lever arm comprises two segments: the vertical distance between the line of action of the force and the first end, and the vertical distance between the line of action of the force and the second end.

[0056] Thus, when the pin is inserted or removed from the sleeve 100, the lever arm at the first clamping arm 120 and / or the second clamping arm 130 is relatively large, which facilitates the deformation of the sleeve 100. Furthermore, it helps to distribute stress during the insertion and removal of the pin, reducing the possibility of abrupt changes in insertion and removal force, making the insertion and removal of the pin smoother and improving the user experience.

[0057] It should be noted that, in the embodiments of this application, both the first clamping arm 120 and the second clamping arm 130 may include a first sub-arm 10 and a second sub-arm 20. Thus, during the insertion and removal of the pin, both the first clamping arm 120 and the second clamping arm 130 can undergo two-stage deformation, thereby reducing the possibility of harsh and unstable insertion and removal forces, and improving the user's feel when inserting and removing the pin.

[0058] Of course, either the first clamping arm 120 or the second clamping arm 130 may include only one of the first sub-arm 10 and the second sub-arm 20. This can also improve the problem of stiff insertion and extraction force to a certain extent and improve the user's feel when inserting or removing the pin. In this case, the other of the first clamping arm 120 and the second clamping arm 130 can be configured with reference to the elastic arm in related technologies.

[0059] It should also be noted that the first direction X is the insertion and removal direction of the pin. Since the second direction Y intersects with the first direction X, the first clamping arm 120 and the second clamping arm 130 distributed along the second direction Y can respectively abut against different sides of the pin to realize the electrical connection between the pin and the socket 100.

[0060] The angle between the first direction X and the second direction Y can be 78°, 85°, 90°, 93° or 99°, etc. The embodiments of this application do not specifically limit the angle between the first direction X and the second direction Y.

[0061] As a preferred approach, the first direction X and the second direction Y can be perpendicular. In this way, when a pin is inserted into the sleeve 100, the first clamping arm 120 and the second clamping arm 130 are distributed on opposite sides of the pin, and the first clamping arm 120 and the second clamping arm 130 are completely aligned, which can make the force on the pin more balanced.

[0062] In some embodiments, such as Figure 3 As shown, a insertion space 30 can be provided between the first clamping arm 120 and the second clamping arm 130. When the pin is inserted into the socket 100, the pin can extend into the insertion space 30 and abut against both the first clamping arm 120 and the second clamping arm 130. At this time, the first clamping arm 120 and the second clamping arm 130 will tightly clamp the pin under their own elasticity. In this way, the abutment between the pin and the socket 100 is more reliable, which can make the transmission of electrical energy more reliable.

[0063] The insert 100 also includes an anti-breakage arm 40. The anti-breakage arm 40 can be connected to the ends of the first clamping arm 120 and the second clamping arm 130 located away from the insert body 110. When the first clamping arm 120 includes a first sub-arm 10 and a second sub-arm 20, the anti-breakage arm 40 can be connected to the second sub-arm 20 of the first clamping arm 120. When the second clamping arm 130 includes a first sub-arm 10 and a second sub-arm 20, the anti-breakage arm 40 can be connected to the second sub-arm 20 of the second clamping arm 130.

[0064] For the first clamping arm 120 and the second clamping arm 130, which do not include the first sub-arm 10 and the second sub-arm 20, but include an elastic arm, the anti-breakage arm 40 can be connected to the elastic arm.

[0065] When the pin is inserted into or removed from the sleeve 100, causing the first clamping arm 120 and the second clamping arm 130 to deform, the anti-bend arm 40 can also rotate along with the second clamping arm 130. During the process of pulling the pin out of the sleeve 100, under the action of the pin, the ends of the first clamping arm 120 and the second clamping arm 130 away from the sleeve body 110 will deform towards each other. At this time, the anti-bend arm 40 will also rotate into the insertion space 30.

[0066] Thus, when the pin is pulled out of the sleeve 100, the anti-breakage arm 40 will restrict the rotation and deformation of the first clamping arm 120 and the second clamping arm 130 to a certain extent. When the rotation and deformation of the first clamping arm 120 and the second clamping arm 130 are large, the anti-breakage arm 40 may come into contact with the pin, thereby reducing the possibility of excessive deformation of the first clamping arm 120 and the second clamping arm 130.

[0067] Furthermore, the anti-bend arm 40 in this application extends away from the insertion space 30, which can reduce the possibility that the anti-bend arm 40's arrangement will affect the normal removal of the pin. Specifically, the anti-bend arm 40 in this application can be seen as extending into the interior of the arched structure formed by the first sub-arm 10 and the second sub-arm 20. That is, the anti-bend arm 40 is located outside the insertion space 30, which can reduce the possibility that burrs or other defects at the anti-bend arm 40 may snag the pin when removing it, making it difficult to remove the pin from the insertion space 30 and affecting the user experience.

[0068] It should be noted that, in the embodiments of this application, when the pin is inserted or removed from the sleeve 100, the anti-bend arm 40 may be a structure that does not deform or has a small amount of deformation.

[0069] In this embodiment of the application, in order to further improve the elasticity of the first clamping arm 120 and the second clamping arm 130, optimize the insertion and extraction force and the user's feel when inserting and removing the pin, the following improvements can be made.

[0070] like Figure 1 and Figure 4 As shown, this application may provide a hole structure extending along the second direction Y on the first clamping arm 120 and / or the second clamping arm 130. The hole structure can improve the elasticity of the first clamping arm 120 and / or the second clamping arm 130 by influencing their rigidity. This facilitates the deformation of the first clamping arm 120 and the second clamping arm 130 during the insertion and removal of the pin, further optimizing the insertion and removal force.

[0071] Specifically, a first adjustment hole 101 may be provided on the first sub-arm 10, and the first adjustment hole 101 extends through the first sub-arm 10 along the second direction Y, such as... Figure 1 and Figure 2As shown. And / or, a second adjustment hole may be provided on the second sub-arm 20, the second adjustment hole penetrating the second sub-arm 20 along the second direction Y.

[0072] For ease of description, this application will describe the case where both the first clamping arm 120 and the second clamping arm 130 include the first sub-arm 10 and the second sub-arm 20. The case where only one of the first clamping arm 120 and the second clamping arm 130 includes the first sub-arm 10 and the second sub-arm 20 will not be described in detail here, but can be referred to the relevant description.

[0073] The first sub-arm 10 of the first clamping arm 120 and the second clamping arm 130 may be provided with a first adjustment hole 101. This allows the first sub-arm 10 to rotate and deform relative to the first end when the pin is inserted or removed, and also allows the first sub-arm 10 to drive the second sub-arm 20 to rotate with the first end. Alternatively, the second sub-arm 20 of the first clamping arm 120 and the second clamping arm 130 may be provided with a second adjustment hole. This allows the second sub-arm 20 to rotate and deform relative to the first end when the pin is inserted or removed.

[0074] Thus, when the pin is inserted into the sleeve 100, the deformation of the first clamping arm 120 and the second clamping arm 130 is facilitated, thereby further reducing the force required to insert the pin and improving the smoothness of the insertion. When the pin is pulled out of the sleeve 100, the first adjustment hole 101 provides appropriate elastic restoring force to the first clamping arm 120 and the second clamping arm 130 so that the pin can be pulled out smoothly.

[0075] Furthermore, the first adjustment hole 101 allows the first clamping arm 120 and the second clamping arm 130 to return to their original positions (the positions before the pin was inserted) after the pin is pulled out, so that the pin can be inserted again later. Especially for scenarios that require frequent insertion and removal of the pin, this makes each insertion and removal of the pin smoother and improves the reliability of the electrical connection between the pin and the socket 100.

[0076] That is, the hole structure in this application can improve the elasticity of the first clamping arm 120 and / or the second clamping arm 130, which facilitates the deformation of the first clamping arm 120 and the second clamping arm 130 during the insertion and removal of the pin, and can optimize the insertion and removal force.

[0077] It is understood that in the sleeve proposed in this application, the dimensions of the first adjustment hole 101 and the second adjustment hole can be adjusted to allow the elasticity of the first clamping arm 120 and the second clamping arm 130 to be larger or smaller. In practical applications, the dimensions of the first adjustment hole 101 and the second adjustment hole can be set according to the actual size of each part, the actual use of the sleeve 100, and the insertion and extraction force required by national standards.

[0078] Furthermore, for the first clamping arm 120 and the second clamping arm 130, either the first adjustment hole 101 or the second adjustment hole can be selectively provided. This reduces the possibility that if both the first adjustment hole 101 and the second adjustment hole are provided, the stiffness of either the first clamping arm 120 or the second clamping arm 130 might be too small, leading to a decrease in the reliability of the clamping pin by the first clamping arm 120 and the second clamping arm 130.

[0079] As a preferred approach, the elasticity of the sleeve 100 can be improved by providing a first adjustment hole 101 on the first clamping arm 120 and / or the second clamping arm 130. This reduces the possibility of a decrease in the contact area between the pin and the sleeve 100 when the second adjustment hole is provided. In other words, by providing the first adjustment hole 101, the reliability of the electrical connection between the pin and the sleeve 100 can be ensured while simultaneously improving the elasticity of the first clamping arm 120 and / or the second clamping arm 130.

[0080] It should be noted that if only one of the first clamping arm 120 and the second clamping arm 130 includes the first sub-arm 10 and the second sub-arm 20, the elasticity of the other arm, which does not include the first sub-arm 10 and the second sub-arm 20, can also be improved by setting a hole structure.

[0081] Alternatively, the insert 100 is typically manufactured by stamping, which requires a stamping die. Considering both the cost of modifying the die and the elasticity of the insert 100, a hole structure can be added to the two elastic arms of the insert, which are already present in related technologies. This allows for the production of an insert with increased elasticity with only minor modifications to the stamping die used in the related technologies.

[0082] It should also be noted that the entire socket 100 is made of conductive materials such as brass; that is, the first clamping arm 120, the second clamping arm 130, and the socket body 110 are all made of conductive materials. The first clamping arm 120 and the second clamping arm 130 are required to frequently clamp and release the pin, while the socket body 110 supports the first clamping arm 120 and the second clamping arm 130 and withstands the impact generated during insertion and removal.

[0083] That is, the insert 100 includes a first clamping arm 120 and a second clamping arm 130 that require deformation, as well as a non-deformable or minimally deformable insert body 110. The different functions and deformation requirements of the insert 100 are mainly achieved through the different shapes and thicknesses of these parts. For example, the first clamping arm 120 is generally curved and has a small thickness. Thus, when the first clamping arm 120 is subjected to force, the curved shape provides a tendency for deformation, allowing it to deform. Meanwhile, the various parts of the insert body 110 can be straight and have a larger thickness, enabling the insert body 110 to withstand greater impacts.

[0084] In some embodiments, such as Figures 1 to 3 As shown, in the second direction Y, the socket body 110 may have a first side arm 111 and a second side arm 112 opposite to each other. A first clamping arm 120 is connected to the first side arm 111, and a second clamping arm 130 is connected to the second side arm 112. The first side arm 111 and the second side arm 112 may also be spaced apart along the second direction Y, thus forming an insertion space 30 between the first clamping arm 120 connected to the first side arm 111 and the second clamping arm 130 connected to the second side arm 112.

[0085] In this application, the insertion and extraction force can be optimized by adjusting the dimensions of the first side arm 111 and / or the second side arm 112, ensuring that the force is neither too small nor too large. If the insertion and extraction force is too small, the connection between the pin and the sleeve 100 is less reliable, and the pin is prone to wobbling within the sleeve 100. If the insertion and extraction force is too large, it will make it difficult for the user to insert or remove the pin from the sleeve 100, and may easily damage the sleeve 100 and the pin.

[0086] Specifically, the dimensions of the first side arm 111 and / or the second side arm 112 in the first direction X can be adjusted. For ease of explanation, the first direction X is referred to as the height direction, the dimension of the first side arm 111 in the first direction X is referred to as the height of the first side arm 111, and the dimension of the second side arm 112 in the first direction X is referred to as the height of the second side arm 112.

[0087] The following detailed description is based on the first side arm 111 as an example. The description of the second side arm 112 can be referred to the description of the first side arm 111, and will not be repeated here.

[0088] The height of the first side arm 111 affects the height of the first clamping arm 120 on the sleeve body 110. When the first clamping arm 120 is under force, it can rotate around the connection position between the first clamping arm 120 and the first side arm 111. According to the inverse relationship between size and stiffness, when the height of the first side arm 111 is larger, the stiffness of the structure formed by the connection between the first side arm 111 and the first clamping arm 120 is smaller. At this time, when the pin is inserted or removed from the sleeve 100, the first clamping arm 120 can rotate more easily around the connection position between itself and the first side arm 111. Correspondingly, at this time, the insertion or removal force required when the pin is inserted or removed is smaller.

[0089] When the height of the first side arm 111 is relatively small, the rigidity of the structure formed by the connection between the first side arm 111 and the first clamping arm 120 is relatively large. In this case, it is more difficult for the first clamping arm 120 to rotate around the connection position between itself and the first side arm 111 when the pin is inserted or removed. Correspondingly, the insertion or removal force required when the pin is inserted or removed is relatively large.

[0090] In this embodiment, the specific height of the first side arm 111 can be combined with other features to improve the insertion and extraction force. For example, a first adjustment hole 101 can be provided on the first clamping arm 120, while the height of the first side arm 111 can be adaptively reduced to make the insertion and extraction force more appropriate.

[0091] In addition, the height of the first side arm 111 also affects the space occupied by the plug sleeve 100. When adjusting the height of the first side arm 111, the size of the space occupied by the plug sleeve 100 and the feasibility of installing the plug sleeve 100 should also be considered.

[0092] In the embodiments of this application, such as Figure 1 , Figure 2 and Figure 5 As shown, when the first clamping arm 120 includes a first sub-arm 10 and a second sub-arm 20, the side of the first sub-arm 10 away from the second clamping arm 130 is a first plane 102, and the first plane 102 and the first side arm 111 have a first included angle α, which satisfies: 5°≤α≤25°.

[0093] That is, the first sub-arm 10 is inclined on the side away from the second clamping arm 130. In this way, when the pin is inserted or removed from the sleeve and the pin presses against the first clamping arm 120, the inclined first sub-arm 10 can provide a tendency to deform, which is conducive to the first sub-arm 10 rotating and deforming around the first end.

[0094] In this application, a first included angle α exists between the first plane 102 of the first sub-arm 10 and the first side arm 111. Since the first included angle α is greater than or equal to 5° and less than or equal to 25°, this reduces the possibility of the first sub-arm 10 becoming substantially flush with the plastic part when the first included angle α is too small. This results in a smaller clearance space between the first clamping arm 120 and the plastic part, reducing the deformation of the first sub-arm 10 and thus mitigating the potential for abrupt changes in insertion and extraction force.

[0095] Furthermore, this also reduces the possibility that when the first included angle α is too large, the first clamping arm 120 occupies a large space in the second direction Y, making it difficult to arrange the first clamping arm 120 and even affecting the size of the insertion space 30. In addition, if the first included angle α is too large, the tilt of the first clamping arm 120 will be aggravated, which will also make the first clamping arm 120 prone to collapse when the pin is inserted.

[0096] Specifically, in this application, the first included angle α can be 5°, 10°, 13.5°, 19° or 20°, etc. The embodiments of this application do not specifically limit the size of the first included angle α.

[0097] In addition to the above-mentioned configuration, the first clamping arm 120 can also have other configurations. For example, the side of the first sub-arm 10 of the first clamping arm 120 that faces away from the second clamping arm 130 can be a first arc surface 103, such as... Figure 2 and Figure 6 As shown.

[0098] The above design allows the side of the first sub-arm 10 facing away from the second clamping arm 130 to be more rounded. This ensures that when the first clamping arm 120 is subjected to force applied by the pin, the force is distributed more evenly on the first sub-arm 10. Furthermore, the curved surface design facilitates the deformation of the first sub-arm 10, reducing localized stress concentration and minimizing the possibility of damage to the first sub-arm 10.

[0099] Similarly, when the second clamping arm 130 includes a first sub-arm 10 and a second sub-arm 20, the side of the first sub-arm 10 facing away from the first clamping arm 120 is a second plane 202. The second plane 202 and the second side arm 112 have a second included angle β, which satisfies: 5° ≤ β ≤ 25°. For details, please refer to [link to relevant documentation]. Figure 1 , Figure 2 and Figure 5 .

[0100] In this embodiment, the second clamping arm 130 is also inclined, which facilitates deformation of the second clamping arm 130 when the pin presses against it. Specifically, the angle between the second plane 202 of the second clamping arm 130 and the second side arm 112 can be between 5° and 25°. For details, please refer to the foregoing description of the first included angle α; this embodiment will not repeat it here.

[0101] Alternatively, the second clamping arm 130 can also have other configurations. For example, in the second clamping arm 130, the side of the first sub-arm 10 facing away from the first clamping arm 120 is a second arc surface 203, as detailed in [reference needed]. Figure 2 and Figure 6 In this way, when the second clamping arm 130 is subjected to force, the force received at the first sub-arm 10 can be distributed more evenly.

[0102] In summary, in the embodiments of this application, the first clamping arm 120 and / or the second clamping arm 130 can adopt a design similar to an arched structure, so that when the pin is inserted or removed from the socket 100, the first clamping arm 120 and / or the second clamping arm 130 can undergo two-stage deformation. In this way, the insertion and removal force changes gradually when the pin is inserted or removed, which can reduce the possibility of unstable insertion and removal force due to sudden increases and decreases, making the user's feel smoother when inserting and removing the pin, thereby improving the user's experience when using the socket.

[0103] It should be noted that the socket 100 proposed in this application can be of different types, such as a live wire socket, a neutral wire socket, and a ground wire socket. Different types of sockets 100 can be used to provide electrical connections between electronic devices and different phase wires.

[0104] In addition, such as Figure 7 As shown, this application also provides a plug assembly 200, including a connecting strip 201 and plugs 100 of any of the above embodiments, with a plurality of plugs 100 connected at intervals to the connecting strip 201.

[0105] In the socket assembly 200, the connecting strip 201 serves to conduct electricity, support, and fix the socket 100. In this way, multiple sockets 100 can be installed through the connecting strip 201, and the connecting strip 201 can realize the electrical connection between multiple sockets 100.

[0106] In electronic devices, the pins typically include two or three metal contacts. Correspondingly, to achieve electrical connection between the pin and the socket assembly 200, the socket assembly 200 should have different types of sockets 100. For example, the connecting strip 201 may have two types of sockets: a live wire socket and a neutral wire socket, or the connecting strip 201 may have three types of sockets: a live wire socket, a neutral wire socket, and a ground wire socket.

[0107] In this application, different types of sockets 100 can be connected to the connecting strip 201 that connects different phase wires. One or more sockets 100 of the same type can be connected to the connecting strip 201 that connects the same phase wire, and so on.

[0108] Furthermore, this application also provides a socket, including the socket assembly 200 in the above embodiments. In this application, the socket can specifically be a three-hole socket, a five-hole socket, a power strip, or a track socket, etc. The socket assembly 200 proposed in this application can be incorporated into all these types of sockets to improve the user experience. The specific arrangement of the connecting strip 201 and the socket 100 in the socket can be adaptively adjusted according to different socket types.

[0109] For example, for a three-hole socket, the connecting strip 201 can be connected to a live wire socket, a neutral wire socket, and a ground wire socket. For a five-hole socket, the connecting strip 201 can be connected to two live wire sockets, two two-wire sockets, and a ground wire socket, and so on. The different ways of setting the sockets 100 and the connecting strip 201 in various sockets will not be described in detail in this embodiment.

[0110] In some embodiments, the socket may further include a housing, on which the socket assembly 200 is mounted. To ensure the electrical insulation performance of the socket, the housing is generally made of plastic. The plastic component in the foregoing embodiments can correspond to the housing of the socket.

[0111] The housing has multiple mounting slots, and multiple inserts 100 are embedded in the mounting slots one by one. In this way, the inserts 100 can be positioned and limited by the mounting slots, which facilitates the installation of the insert assembly 200 in the housing.

[0112] like Figure 1 and Figure 3 As shown, in the second direction Y, the mounting groove has opposing first groove walls 300 and second groove walls 400. A first support boss 50 is connected to the side of the insert body 110 facing the first groove wall 300, and the first support boss 50 mates with the first groove wall 300. In the case where the insert body 110 includes a first side arm 111 and a second side arm 112, the first support boss 50 can specifically be connected to the first side arm 111.

[0113] Thus, the first side arm 111 can contact the housing via the first support boss 50, and the housing can provide a certain supporting force to the sleeve 100 by supporting the first support boss 50. This creates an additional support on the first side arm 111. When the pin is inserted into the sleeve 100 and the pin presses against the first clamping arm 120, this support can provide a fulcrum for the first side arm 111, thereby limiting the rotation of the first sub-arm 10 around the first end. In this way, the normal pressure of the first clamping arm 120 on the pin can be increased, thereby improving the insertion and extraction force.

[0114] To make the solution and beneficial effects of this application clearer, a specific analysis is conducted here in the case where the first support boss 50 is not provided on the first groove wall 300.

[0115] When the first support boss 50 is not provided on the first side arm 111, there is no additional support between the first side arm 111 and the first groove wall 300. In this way, when the first clamping arm 120 is subjected to force, the first sub-arm 10 can easily rotate and deform around the first end. At this time, the first side arm 111 is in the form of a cantilever beam.

[0116] When a first support boss 50 is provided on the first side arm 111, the first support boss 50 can cooperate with the first groove wall 300 to provide support for the first side arm 111. Adding the first support boss 50 as a fulcrum to the first side arm 111 makes the first side arm 111 resemble a double-support beam. This will increase the rigidity of the first side arm 111 to a certain extent, thus limiting the deformation at the first end of the first side arm 111, thereby reducing the deformation of the first sub-arm 10 around the first end and increasing the insertion and extraction force.

[0117] In this application, the first support boss 50 increases the insertion and extraction force. The first support boss 50 can cooperate with other features to coordinate the user's feel, improve the smoothness of insertion and extraction, and meet the insertion and extraction force required by national standards. For example, if the first clamping arm 120 has a first adjustment hole 101, the elasticity of the first clamping arm 120 may be too large, resulting in a small insertion and extraction force required when inserting or removing the pin. In this case, the insertion and extraction force can be appropriately increased by setting the first support boss 50 and adjusting its size so that the socket can meet the national standards.

[0118] Here, this application also describes the case where the insertion and extraction force is adjusted by adjusting the size of the first support boss 50. In the second direction Y, the first support boss 50 has a first dimension L1, which satisfies: 0 < L1 ≤ 0.4 mm. For details, please refer to [reference needed]. Figure 3 .

[0119] In a socket, the dimensions of the mounting groove for installing the socket sleeve 100 are generally fixed. Therefore, the size of the first dimension of the first support boss 50 will change the fit between the first support boss 50 and the first groove wall 300. When the first dimension is smaller, there is a clearance fit between the first support boss 50 and the first groove wall 300. In this case, the supporting force of the first groove wall 300 on the first support boss 50 is smaller, the impact on the deformation of the first clamping arm 120 is smaller, and the degree of provision of insertion and extraction force is also smaller.

[0120] When the initial dimension is large, there is an interference fit between the first support boss 50 and the first groove wall 300. In this case, the first groove wall 300 provides significant support to the first support boss 50. Due to the interference fit, the first groove wall 300 will press against the first side arm 111 through the first support boss 50, causing the first side arm 111 to tend to deform the first clamping arm 120 away from the first groove wall 300, or to deform by a small amount away from the first groove wall 300. This reduces the size of the insertion space 30 between the first clamping arm 120 and the second clamping arm 130, which significantly improves the insertion and extraction force.

[0121] In this embodiment, the first support boss 50 of appropriate size can be selected according to the different degrees of improvement in insertion and extraction force. The first size L1 can be 0.2mm, 0.29mm, 0.3mm, 0.38mm or 0.4mm, etc. The specific value of the first size L1 is not specifically limited in this embodiment.

[0122] In this application, the range 0 < L1 ≤ 0.4 mm is defined based on the distance between the first side arm 111 and the first groove wall 300 under normal circumstances. When this range is met, the size of the first support boss 50 will not be too large, thereby reducing the possibility of the plug sleeve 100 failing to be installed properly.

[0123] Additionally, in this embodiment, a second support boss 60 may be connected to the side of the insert body 110 facing the second groove wall 400. The second support boss 60 cooperates with the second groove wall 400, such as... Figure 1 and Figure 3 As shown. When the socket body 110 includes a first side arm 111 and a second side arm 112, the first support boss 50 can be specifically connected to the first side arm 111. In this way, there will also be an additional support on the second side arm 112 to improve the insertion and extraction force.

[0124] At this time, in the second direction Y, the second support boss 60 has a second dimension L2, which satisfies: 0 < L2 ≤ 0.4 mm. For the specific influence of the setting of the second support boss 60 on the insertion and extraction force, and the specific influence of the dimension of the second support boss 60 in the second direction Y on the insertion and extraction force, please refer to the previous description of the first support boss 50. This embodiment will not be repeated here.

[0125] It is understood that, in the embodiments of this application, only one of the first support boss 50 and the second support boss 60 may be provided, or both may be provided. This application does not impose specific limitations on this.

[0126] Finally, it should be noted that the above embodiments are only specific implementations of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the protection scope of this application.
