Description

Technical Field

[0001] The present application relates to the technical field of socket equipment, and in particular to a dustproof strip of a power track, a power track and a power track socket. Background Art

[0002] The power rail socket is a socket system used for power supply and data transmission. It consists of a power rail and an adapter and can be flexibly arranged and used. The plug-in arranged at the bottom of the adapter is plugged into the track groove arranged at the top of the power rail. At the same time, a locking mechanism for fixing the plug-in is arranged in the power rail to achieve a stable connection between the power rail and the adapter. When the adapter is not plugged into the power rail, external dust, debris or other dirt enters the interior of the power rail through the track groove, which will affect the safety of the power rail socket. Therefore, it is necessary to set a dustproof structure in the power rail to block the track groove to prevent external dust, debris or other dirt from entering the interior of the power rail through the track groove.

[0003] In the related art, in order not to affect the smooth plugging of the adapter, the dustproof structure is a pair of elastic dustproof strips that abut against each other. The force generated by the adapter plug during the plugging process separates the abutting part of the dustproof strips, so that the adapter plug can be smoothly inserted into the power rail. However, since the elastic dustproof strip is made of soft material, the part of the dustproof strip fixed in the power rail is also prone to deformation, causing the dustproof strip to fall off the power rail, affecting the dustproof effect of the dustproof strip, and thus affecting the safety of the power rail socket. Utility Model Content

[0004] The present application provides a dustproof strip for a power track, a power track and a power track socket, so as to solve the problem that the dustproof strip falls off from the power track, affecting the dustproof effect of the dustproof strip and thus affecting the safety of the power track socket.

[0005] In a first aspect, the present application provides a dust-proof strip for an electric track, which is used to cover a track groove opened on the electric track housing, and the dust-proof strip comprises: a first section and a second section; the first section is arranged in the electric track housing; the second section is connected to the first section and extends in a first direction until the second section extends into the track groove away from one end of the first section, and the second section is made of the soft material; the first direction is the direction in which the electric track housing points to the track groove; a first protruding structure is arranged on the first section, and the first protruding structure is made of a hard material; a first limiting rib is arranged in the electric track housing, the first limiting rib is located between the first protruding structure and the track groove, and the first limiting rib abuts against the first protruding structure to prevent the first section from falling out of the electric track housing.

[0006] According to the first aspect, the dust strip includes a first section and a second section, the first section is arranged in the power rail housing, and is used to fix the dust strip in the power rail housing; the first direction is the direction in which the power rail housing points to the rail groove, the second section is connected to the first section and extends in the first direction, and extends from the power rail housing to the rail groove; the second section can be used to prevent external dust, debris or other dirt from entering the power rail through the rail groove, thereby ensuring the safety of the power rail socket. The second section is set to a soft material, and the soft material is easy to bend to avoid the component structure that needs to be plugged into the rail groove.

[0007] The first protruding structure provided on the first section abuts against the first limiting rib provided in the power rail housing. Since the first limiting rib is located between the first protruding structure and the rail groove, and the first direction is the direction in which the power rail housing points to the rail groove, the first section will not fall out of the power rail along the first direction, thereby fixing the dust strip in the power rail housing. In the related art, the dust strip is generally made of soft material, which is mostly highly elastic material and easy to deform, causing the first protruding structure and the second protruding structure to deform, thereby causing the first section to lose its fixing function, causing the dust strip to fall out of the power rail housing. The first protruding structure is made of hard material, which has the characteristic of not being easily deformed, and can make the fixed connection between the dust strip and the power rail housing more stable, so as to solve the problem in the related art that the dust strip falls out of the power rail housing, affecting the dustproof effect of the dust strip, thereby affecting the safety of the power rail socket.

[0008] In a possible design, the first protruding structure is wrapped with the soft material.

[0009] According to the embodiment, the first protruding structure is made of hard material, and the soft material is wrapped outside the first protruding structure, so that the part of the first section that contacts the power rail shell is made of soft material, so that the first section and the power rail shell can be interference connected, thereby making the fixed connection between the first section and the power rail shell more stable.

[0010] In a possible design, along the first direction, the first protrusion structure and the second protrusion structure are sequentially arranged on the first section; there is a first groove between the first protrusion structure and the second protrusion structure, and the first protrusion structure and the second protrusion structure are made of hard material; the first limiting rib is clamped in the first groove, so that the first protrusion structure and the second protrusion structure are respectively abutted against two sides of the first limiting rib.

[0011] According to the embodiment, the first section is provided with a first protruding structure and a second protruding structure in sequence along the first direction, and a first groove exists between the first protruding structure and the second protruding structure. The first limiting rib is clamped in the first groove, so that the first protruding structure and the second protruding structure respectively abut against the two sides of the first limiting rib, thereby realizing double-point limiting for the first section, improving the limiting stability, and fixing the dust strip more firmly in the power rail housing. The first protruding structure and the second protruding structure are both hard materials that are not easily deformed, further strengthening the fixed connection between the first section and the power rail housing.

[0012] In a possible design, the first protruding structure and the second protruding structure are wrapped with the soft material.

[0013] According to the embodiment, the first protrusion structure and the second protrusion structure are made of hard material, and soft material is wrapped around the first protrusion structure and the second protrusion structure, so that the part of the first section that contacts the power rail shell is made of soft material, so that the first section and the power rail shell can be interference connected, thereby making the fixed connection between the first section and the power rail shell more stable.

[0014] In a possible design, the first groove is made of a hard material.

[0015] According to this embodiment, the first protruding structure, the second protruding structure and the first groove are all made of hard material, which further strengthens the fixed connection between the first section and the power rail housing.

[0016] In a possible design, the first protruding structure, the second protruding structure and the first groove are wrapped with the soft material.

[0017] According to the embodiment, the first protrusion structure, the second protrusion structure and the first groove are all made of hard material, and the soft material is wrapped around the first protrusion structure, the second protrusion structure and the first groove, so that the part of the first section that contacts the power rail housing is made of soft material, so that the first section and the power rail housing can be interference connected, thereby making the fixed connection between the first section and the power rail housing more stable.

[0018] In a possible design, the hard material and the soft material are the same material, and the hardness of the hard material is greater than the hardness of the soft material.

[0019] Through the implementation provided, the hard material and the soft material use the same material with different hardness. While retaining the characteristics of the hard material and the soft material, the structural integrity of the dustproof strip is made higher, the structural strength of the dustproof strip is improved, thereby extending the service life of the dustproof strip and reducing production costs.

[0020] In a possible design, an end of the second section connected to the first section is a first end, an end of the second section away from the first section is a second end, and a thickness of the second end is less than a thickness of the first end.

[0021] Through this implementation, the thickness of the first end offsets the wear of the second section caused by bending, thereby increasing the life of the dust strip and reducing production costs; at the same time, the thickness of the second end is less than that of the first end, making the second end easy to deform, and the component structure inserted in the track groove can easily bend the second end to facilitate insertion.

[0051] like Figure 1 and Figure 2As shown, an embodiment of the first aspect of the present application provides a dust strip 10 of an electric track 1, which is used to cover a track groove 21 opened on an electric track housing 20, and the dust strip 10 includes: a first section 11 and a second section 12; the first section 11 is arranged in the electric track housing 20; the second section 12 is connected to the first section 11 and extends in a first direction X until the second section 12 extends into the track groove 21 away from one end of the first section 11, and the second section 12 is made of a soft material; the first direction X is the direction in which the electric track housing 20 points to the track groove 21; a first protruding structure 111 is arranged on the first section 11, and the first protruding structure 111 is made of a hard material; a first limiting rib 22 is arranged in the electric track housing 20, the first limiting rib 22 is located between the first protruding structure 111 and the track groove 21, and the first limiting rib 22 abuts against the first protruding structure 111, so as to prevent the first section 11 from falling out of the electric track housing 20.

[0052] In some embodiments, the top surface of the power rail housing 20 is a rectangular plane, which includes two corresponding long sides and two corresponding short sides, the length of the long side is much greater than the length of the short side, and the track groove 21 is opened on the top surface of the power rail housing 20. The direction of the power rail housing 20 pointing to the track groove 21 is the direction of the short side. During the assembly process of the dust strip 10, the dust strip 10 needs to be slid into the power rail housing 20 from the first end 121 of the long side until the end of the dust strip 10 that first slides into the power rail housing 20 slides to the second end 122 of the long side.

[0053] Specifically, the dust strip 10 includes an integrally formed first section 11 and a second section 12. The first section 11 is slidably connected in the power rail housing 20 to fix the dust strip 10 in the power rail housing 20. The second section 12 is connected to the first section 11 and extends in the first direction X. Since the first direction X is the direction in which the power rail housing 20 points to the track groove 21, the second section 12 will extend from the power rail housing 20 to the track groove 21; therefore, the second section 12 can be used to prevent external dust, debris or other dirt from entering the interior of the power rail 1 through the track groove 21, thereby ensuring the safety of the power rail socket 100.

[0054] Furthermore, if Figure 3 As shown, the plug-in piece (not shown in the figure) of the adapter 2 is plugged into the track groove 21 at the top of the power track 1, and the second section 12 is set to a soft material that is easy to deform. The force generated by the plug-in piece of the adapter 2 during the plug-in process can cause the second section 12 to bend to avoid the plug-in piece, so that the adapter 2 can be smoothly plugged into the power track 1, thereby ensuring the normal operation of the power track socket 100.

[0055] Exemplarily, the soft material may be TPU, silicone, or other soft materials with high elasticity.

[0056] Specifically, TPU (Thermoplastic Polyurethane), thermoplastic polyurethane. It has excellent elasticity and wear resistance, as well as high tension, high strength and high durability.

[0057] Exemplarily, the hard material may be PC, PBT, or other hard materials with support properties.

[0058] Specifically, PC (Polycarbonate) has good rigidity, strength and impact resistance, as well as excellent heat resistance, chemical resistance and weather resistance.

[0059] PBT (Polybutylene Terephthalate), polybutylene terephthalate. It has good rigidity and strength, as well as high heat resistance and chemical resistance.

[0060] Those skilled in the art can select any one of the above-mentioned soft materials and any one of the above-mentioned hard materials according to production conditions and production requirements.

[0061] The dust strip 10 provided by the embodiment of the first aspect of the present application includes a first section 11 and a second section 12. The first section 11 is arranged in the power rail housing 20, and is used to fix the dust strip 10 in the power rail housing 20; the first direction X is the direction in which the power rail housing 20 points to the track groove 21, and the second section 12 is connected to the first section 11 and extends in the first direction X, and extends from the power rail housing 20 to the track groove 21; the second section 12 can be used to prevent external dust, debris or other dirt from entering the inside of the power rail 1 through the track groove 21, thereby ensuring the safety of the power rail socket 100. The second section 12 is set to a soft material, and the soft material is easy to bend to avoid the component structure that needs to be plugged into the track groove 21.

[0062] The first protruding structure 111 provided on the first section 11 abuts against the first limiting rib 22 provided in the power rail housing 20. Since the first limiting rib 22 is located between the first protruding structure 111 and the rail groove 21, and the first direction X is the direction in which the power rail housing 20 points to the rail groove 21, the first section 11 will not fall out of the power rail 1 along the first direction X, thereby fixing the dust strip 10 in the power rail housing 20. In the related art, the dust strip 10 is generally made of soft material, which is mostly highly elastic and easy to deform, causing the first protruding structure 111 and the second protruding structure 112 to deform, thereby causing the first section 11 to lose its fixing function, causing the dust strip 10 to fall out of the power rail housing 20. The first protrusion structure 111 is made of a hard material, which is not easily deformed, and can make the fixed connection between the dust strip 10 and the power track housing 20 more stable, so as to solve the problem in the related art that the dust strip 10 is detached from the power track housing 20, affecting the dustproof effect of the dust strip 10, thereby affecting the safety of the power track socket 100.

[0063] On the other hand, during the assembly process of the dust strip 10, the first section 11 needs to slide in the power rail housing 20, and the soft material will cause the first section 11 to deform or bend during the assembly process, thereby increasing the difficulty of assembling the dust strip 10, increasing the assembly time, and thus increasing the production cost. When the first protruding structure 111 is made of a hard material that is not easily deformed, the first section 11 will avoid deformation or bending during the assembly process under the support of the hard material, thereby reducing the difficulty of assembling the dust strip 10, shortening the assembly time, and thus reducing the production cost.

[0064] In some embodiments, the first protrusion structure 111 is wrapped with a soft material.

[0065] Exemplarily, an interference fit may be used between the first section 11 and the power rail housing 20 to make the fixed connection between the first section 11 and the power rail housing 20 more stable. For example, the portions of the first section 11 in contact with the power rail housing 20 are all made of soft material, which is compressed and deformed, and generates a reverse force on the power rail housing 20, so that the fixed connection between the first section 11 and the power rail housing 20 is more stable.

[0066] Specifically, Figure 1 As shown, the first protrusion structure 111 is wrapped with a hard material inner core 13 which is different from the material of the rest of the dust strip 10. The cross-section of the inner core can be any shape, such as circular, rectangular, triangular, etc., which is not limited here.

[0067] According to the embodiment, the first protruding structure 111 is made of a hard material, and a soft material is wrapped outside the first protruding structure 111, so that the part of the first section 11 that contacts the power rail housing 20 is made of a soft material, so that the first section 11 and the power rail housing 20 can be an interference connection, thereby making the fixed connection between the first section 11 and the power rail housing 20 more stable.

[0068] In some embodiments, Figure 4 As shown, along the first direction X, the first section 11 is sequentially provided with a first protruding structure 111 and a second protruding structure 112; there is a first groove 113 between the first protruding structure 111 and the second protruding structure 112, and the first protruding structure 111 and the second protruding structure 112 are made of hard material; the first limiting rib 22 is clamped in the first groove 113, so that the first protruding structure 111 and the second protruding structure 112 respectively abut against the two sides of the first limiting rib 22.

[0069] Specifically, the contact point between the first protrusion structure 111 and the first limiting rib 22 is the first limiting point of the first section 11, and the contact point between the second protrusion structure 112 and the first limiting rib 22 is the second limiting point of the first section 11. The two limiting points limit the first section 11 at the same time, thereby improving the limiting stability.

[0070] According to the embodiment, the first section 11 is provided with a first protruding structure 111 and a second protruding structure 112 in sequence along the first direction X, and a first groove 113 exists between the first protruding structure 111 and the second protruding structure 112. The first limiting rib 22 is clamped in the first groove 113, so that the first protruding structure 111 and the second protruding structure 112 respectively abut against the two sides of the first limiting rib 22, thereby realizing double-point limiting of the first section 11, improving the limiting stability, and fixing the dust strip 10 more firmly in the power rail housing 20. The first protruding structure 111 and the second protruding structure 112 are both hard materials that are not easily deformed, further strengthening the fixed connection between the first section 11 and the power rail housing 20.

[0071] In some embodiments, the first protruding structure 111 and the second protruding structure 112 are wrapped with a soft material.

[0072] Specifically, Figure 4 As shown, the first protruding structure 111 and the second protruding structure 112 are both wrapped with a hard material inner core 13 which is different from the material of the rest of the dust strip 10. The cross-section of the inner core can be any shape, such as circular, rectangular, triangular, etc., which is not limited here.

[0073] Provided by this embodiment, the first protrusion structure 111 and the second protrusion structure 112 are made of hard material, and the soft material is wrapped outside the first protrusion structure 111 and the second protrusion structure 112, so that the parts of the first section 11 in contact with the power rail housing 20 are all made of soft material, so that an interference connection can be achieved between the first section 11 and the power rail housing 20, thereby making the fixed connection between the first section 11 and the power rail housing 20 more stable.

[0074] In addition, as Figure 5 shown, when the dust-proof strip 10 in the embodiment of the present application has both the first protrusion structure 111 and the second protrusion structure 112, the second protrusion structure 112 may not adopt a hard material, and only the first protrusion structure 111 adopts a hard material, and the double-point limit of the first section 11 can also be achieved.

[0075] Furthermore, when only the first protrusion structure 111 adopts a hard material, the first protrusion structure 111 is wrapped with a soft material, that is, only the first protrusion structure 111 contains a hard material inner core 13.

[0076] In some embodiments, the first groove 113 is made of hard material.

[0077] Provided by this embodiment, the first protrusion structure 111, the second protrusion structure 112 and the first groove 113 are all made of hard material, which further strengthens the fixed connection between the first section 11 and the power rail housing 20.

[0078] In some embodiments, the first protrusion structure 111, the second protrusion structure 112 and the first groove 113 are wrapped with soft material.

[0079] Specifically, the first protrusion structure 111, the second protrusion structure 112 and the first groove 113 all contain a hard material inner core 13 made of a material different from the rest of the dust-proof strip 10. The cross-section of the inner core can be any shape, such as circular, rectangular, triangular, etc., and is not limited here.

[0080] In addition, as Figure 6 shown, the hard material inner cores 13 contained in the first protrusion structure 111, the second protrusion structure 112 and the first groove 113 can be fused into one. For example, the cross-section of the inner core can be "concave" shaped, where the two protruding parts of the "concave" character are located at the first protrusion structure 111 and the second protrusion structure 112 respectively, and the recessed part in the middle of the "concave" character is located at the first groove 113.

[0081] According to the embodiment, the first protruding structure 111, the second protruding structure 112 and the first groove 113 are all made of hard materials, and the soft material is wrapped around the first protruding structure 111, the second protruding structure 112 and the first groove 113, so that the part of the first section 11 in contact with the power rail housing 20 is made of soft material, so that the first section 11 and the power rail housing 20 can be interference connected, thereby making the fixed connection between the first section 11 and the power rail housing 20 more stable.

[0082] In some embodiments, the first section 11 may be entirely made of hard material.

[0083] For example, Figure 7 As shown, the first section 11 is entirely made of a hard material inner core 13 .

[0084] Compared with the dust strips 10 in the above embodiments, when the first section 11 is made of hard material, the overall structure of the dust strip 10 is simple and the cost is low, but the first section 11 does not have the condition of interference connection with the power rail housing 20. Those skilled in the art can select any one of the dust strips 10 in the above embodiments according to different production needs.

[0085] In some embodiments, the hard material and the soft material are the same material, and the hardness of the hard material is greater than the hardness of the soft material.

[0086] The first section 11 and the second section 12 are an integrally molded structure, generally using an injection molding process. When the injection molding process is used, if the materials are the same, the structure after molding has higher integrity and better molding effect, thereby improving the strength of the integrally molded structure, thereby extending the service life of the structure and reducing production costs.

[0087] Exemplarily, both the hard material and the soft material can be TPU. TPU includes high-hardness TPU and low-hardness TPU. High-hardness TPU has high strength and rigidity and can be used as a hard material for a supporting structure. Low-hardness TPU has good softness and bendability and can be used as a soft material for a deformable structure.

[0088] Through the implementation provided, the hard material and the soft material use the same material with different hardness. While retaining the characteristics of the hard material and the soft material, the structural integrity of the dust strip 10 is higher, the structural strength of the dust strip 10 is improved, and the service life of the dust strip 10 is extended, thereby reducing production costs.

[0089] In some embodiments, Figure 5 , Figure 6 and Figure 7As shown, the end of the second section 12 connected to the first section 11 is the first end 121 , the end of the second section 12 away from the first section 11 is the second end 122 , and the thickness of the second end 122 is less than the thickness of the first end 121 .

[0090] Specifically, the component structure inserted in the track groove 21 causes the second section 12 to bend. Since the component structure has a certain thickness, the bending point is generally located at the first end 121 where the second section 12 is connected to the first section 11. The thickness of the first end 121 is relatively thick, which is conducive to offsetting the wear of the second section 12 caused by bending, thereby increasing the life of the dust strip 10 and reducing production costs. Moreover, the smaller the thickness of the second end 122, the easier it is for the second end 122 to deform, and the component structure inserted in the track groove 21 can easily cause the second end 122 to bend, so as to complete the insertion.

[0091] Through this embodiment, the thickness of the first end 121 offsets the wear of the second section 12 caused by bending, thereby increasing the life of the dust strip 10 and reducing the production cost; at the same time, the thickness of the second end 122 is less than the thickness of the first end 121, so that the second end 122 is easy to deform, and the component structure inserted in the track groove 21 can easily bend the second end 122 to facilitate the insertion.

[0092] like Figure 1 and Figure 2 As shown, an embodiment of the second aspect of the present application provides a power track 1, comprising: the dust strip 10 and the power track housing 20 described in any one of the above embodiments; the power track housing 20 comprises a first side track housing 23 and a second side track housing 24 symmetrically arranged; there is a first gap between the first side track housing 23 and the second side track housing 24, and the track groove 21 is the first gap; the first sections 11 of the two dust strips 10 are respectively arranged on the first side track housing 23 and the second side track housing 24, and the second sections 12 of the two dust strips 10 extend respectively in the first direction X until they abut against each other.

[0093] Specifically, the track groove 21 is opened on the top surface of the power track housing 20, so that the power track housing 20 is divided into a first side track housing 23 and a second side track housing 24 along the short side direction by the track groove 21. The power track 1 includes two dustproof strips 10, which are respectively arranged on the first side track housing 23 and the second side track housing 24, and the second sections 12 of the two dustproof strips 10 extend in the first direction X respectively until they abut against each other and completely cover the track groove 21 to ensure the dustproof effect of the power track 1.

[0094] like Figure 1 and Figure 3As shown, an embodiment of the third aspect of the present application provides a power track socket 100, comprising: the power track 1 and the adapter 2 described in any one of the above embodiments; the plug of the adapter 2 is plugged into the track groove 21 of the power track 1; when the adapter 2 is connected to the power track 1, the dust strip 10 of the power track 1 is bent into the track groove 21, and there is friction between the plug and the second section 12 of the dust strip 10.

[0095] Specifically, the force generated by the plug of the adapter 2 during the plugging process can cause the second section 12 to bend to avoid the plug. When the plug is located in the track groove 21, the bent second section 12 is made of a soft material with high elasticity, so the second section 12 has a reset potential after bending and deformation, so that the second section 12 is closely attached to the plug of the adapter 2. And the soft material with high elasticity generally has a high surface tension, so that the second section 12 provides a large friction resistance for the plug of the adapter 2, thereby improving the stability of the plug-in connection between the adapter 2 and the power rail.

[0096] Furthermore, if Figure 3 As shown, one or more adapters 2 can be plugged into the circuit track 20. The adapters 2 include a weak current adapter 2a and a strong current adapter 2b.

[0097] For example, the power rail socket 100 in the embodiment of the present application is used in a kitchen scene. The dust strip 10 provided on the power rail 1 of the power rail socket 100 can prevent water vapor generated in the kitchen from entering the power rail socket 100 through the rail groove 21, and prevent the conductive parts in the power rail socket 100 from short-circuiting, thereby ensuring the safety and reliability of the power rail socket 100 when used in the kitchen scene.
