TECHNICAL FIELD
[0001] The utility model relates to socket indicating lamp technical field especially, relates to a socket indicating lamp connecting structure. BACKGROUND
[0002] In the field of electrical socket, indicating lamp as key function component, it is mainly used to show power on-off state or equipment working state. At present, socket indicating lamp usually adopts LED or neon lamp (NEON) as light source, and forms electrical connection through lamp line and internal conductive copper piece. According to the different connection mode, the lamp line end of traditional technical scheme is welded micro spring, and the surface of copper piece is pressed by the elastic deformation of spring to realize contact. But spring processing and welding process increase material cost and process complexity, to reduce production cost, part of manufacturers adopt the design of plastic rib position direct pressure joint lamp line and copper piece, and the surface of copper piece is formed with surface contact after lamp line deformation.
[0003] However, the rigidity and elastic modulus of plastic material (such as PA, PC, etc.) are far lower than that of metal. In order to achieve sufficient contact pressure, the rib position needs to be compressed excessively by forced deformation to make the lamp line, which causes the plastic part to bear stress exceeding the yield strength of the material for a long time, and the rib position is easily deformed or broken permanently, eventually causing poor contact. Or, the edge or corner of the plastic rib position may directly scratch the surface of the copper piece during the pressing process due to the mismatch of material hardness, forming micro scratches or even local depressions, which not only reduces the conductive cross-sectional area of the copper piece, but also accelerates the fatigue of the copper material due to stress concentration, and is easy to cause crack propagation in a long-term plug-in or vibration environment, causing the copper piece to fail.
[0004] Therefore, there is an urgent need for a new connection structure that can maintain low cost advantage and avoid damage to the copper piece. INVENTION CONTENTS
[0005] The utility model aims at providing a socket indicating lamp connecting structure to solve the technical defects of traditional plastic pressing mode.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A socket indicating lamp connecting structure, comprising: a socket cover, an indicating lamp and a conductive component, the indicating lamp is electrically connected with a conductive wire; the conductive wire and the conductive component are located on one side of the socket cover;The first plug-in part is formed on the socket cover, the second plug-in part is formed on the conductive component, and the first plug-in part is inserted with the second plug-in part;The conductive wire is located between the first plug-in part and the second plug-in part, and the conductive wire is abutted on the second plug-in part under the action of the first plug-in part.
[0008] According to the technical means, the mechanical interlocking structure of the first plug-in part and the second plug-in part is used to replace the direct compression connection of the plastic rib, and the hard contact between the plastic and the copper part in the traditional structure is eliminated. The conductive wire directly realizes electrical contact through the clamping action of the first plug-in part and the second plug-in part, without welding or complex wiring operation, which significantly shortens the assembly time and reduces the risk of human operation failure. At the same time, the edge of the first plug-in part avoids scratching the surface of the conductive assembly, eliminates micro scratches and stress concentration caused by the fatigue of the conductive assembly, and prolongs the service life of the conductive assembly.
[0009] Further, the first plug-in part and the second plug-in part are in interference fit.
[0010] According to the technical means, the first plug-in part and the second plug-in part are in interference fit, so that the assembly has a certain tightness, and a continuous clamping force is generated between the first plug-in part and the second plug-in part, ensuring stable contact between the conductive wire and the conductive assembly.
[0011] Further, the second plug-in part includes a through hole and a flange, the flange is formed around the through hole, the first plug-in part can pass through the through hole and is in interference fit with the flange.
[0012] According to the technical means, the first plug-in part and the flange are in interference fit, and the tight fixation is realized through the friction between the materials, which effectively prevents the connection from loosening or accidentally separating. The flange structure wraps around the periphery of the through hole, which can guide the first plug-in part to quickly align and insert, simplifying the installation operation. At the same time, the flange increases the contact area, making the stress distribution more uniform, thereby improving the overall structural strength of the connection.
[0013] Further, at least one gap is formed on the flange.
[0014] According to the technical means, the gaps on the flange are distributed along the axial direction of the flange, so that the flange is more easily deformed elastically when in interference fit, reducing the axial force required for the insertion of the first plug-in part and improving the assembly efficiency. At the same time, the gaps segment the flange, allowing each region to independently adapt to the shape of the first plug-in part, avoiding local stress concentration and improving connection stability.
[0015] Further, the first plug-in part is a hollow cylindrical structure, and a cavity is formed inside the first plug-in part, one end of the conductive wire is arranged in the cavity.
[0016] According to the technical means, the conductive wire is arranged in the cavity of the first plug-in part, which can avoid mechanical collision with other components and improve the service life of the conductive wire. At the same time, the conductive wire is directly arranged through the preformed cavity, and the cavity radially restricts the conductive wire, without the need for additional fixing devices to prevent the conductive wire from loosening due to vibration or pulling in long-term use.
[0017] Further, the first plug end is formed with a groove, the cavity is communicated with the groove; and at least part of the conductive wire is located in the groove.
[0018] According to the above technical means, the groove structure provides a clear installation position for the conductive wire, ensures the accurate position of the conductive wire in the cavity, and avoids poor contact due to deviation.
[0019] Further, the first plug end is further formed with a limiting piece, after the first plug is plugged into the second plug, the limiting piece abuts against the turned edge, so as to prevent the first plug from falling off.
[0020] According to the above technical means, the limiting piece abuts against the turned edge to form a physical block, and cooperates with the interference fit, so as to further prevent the first plug from falling off due to vibration or external force, and significantly improve the connection reliability.
[0021] Further, the socket cover body is further formed with a reinforcing piece, the reinforcing piece is connected between the first plug and the socket cover body.
[0022] According to the above technical means, the reinforcing piece directly connects the first plug and the socket cover body to form a triangular support structure, effectively disperses the axial and radial stress generated in the plugging process, and prevents the root of the first plug from being broken due to repeated plugging or external force impact.
[0023] Further, the first plug is made of an insulating material.
[0024] According to the above technical means, the insulating material blocks the current path between the first plug and the external environment or adjacent metal parts, effectively prevents the risk of short circuit, electric leakage or accidental electric shock, and improves the safety of equipment use.
[0025] Further, the second plug and the conductive assembly are an integral forming structure.
[0026] According to the above technical means, the integral forming eliminates the joint and the material interface, so that there is no weak point at the joint between the second plug and the conductive assembly, and the overall torsion resistance, bending resistance and impact resistance are significantly improved. At the same time, the material continuity reduces the contact resistance, and improves the electrical connection stability. Since the second plug does not need to be manufactured separately and subsequent welding or assembly steps are not needed, the tool clamps and manual operation are reduced, and the production cost and time are reduced.
[0027] The utility model realizes the beneficial effect that:
[0028] The utility model discloses a first plug connector and the mechanical interlocking structure of second plug connector replace the direct compression joint of plastic muscle position, eliminate the hard contact between plastic and copper in traditional structure.

[0049] Embodiment one
[0050] As Figure 1As shown, the embodiment proposes a socket indicator lamp connecting structure, which comprises a socket cover body 1, an indicator lamp 2 and a conductive assembly 3. The conductive wire 4 is electrically connected to the indicator lamp 2. The conductive wire 4 and the conductive assembly 3 are located on one side of the socket cover body 1. The first plug-in part 11 is formed on the socket cover body 1, and the second plug-in part 31 is formed on the conductive assembly 3. The first plug-in part 11 is inserted into the second plug-in part 31. The conductive wire 4 is located between the first plug-in part 11 and the second plug-in part 31. The conductive wire 4 is abutted on the second plug-in part 31 under the action of the first plug-in part 11.
[0051] In the embodiment, the mechanical interlocking structure of the first plug-in part 11 and the second plug-in part 31 is adopted to replace the direct crimping of the plastic rib, which eliminates the hard contact between the plastic and the copper part in the traditional structure. The conductive wire 4 directly realizes electrical contact through the clamping action of the first plug-in part 11 and the second plug-in part 31, without welding or complex wiring operation, which significantly shortens the assembly time and reduces the risk of human operation failure. At the same time, the edge of the first plug-in part 11 avoids scratching the surface of the conductive assembly 3, eliminating the micro scratches and stress concentration caused by the fatigue of the conductive assembly 3, and prolonging the service life of the conductive assembly 3.
[0052] As shown in Figures 1-4 , the first plug-in part 11 and the second plug-in part 31 are inserted and matched with interference.
[0053] In the embodiment, the first plug-in part 11 and the second plug-in part 31 adopt interference fit, so that there is a certain tightness during assembly. The continuous clamping force is generated between the first plug-in part 11 and the second plug-in part 31, which ensures the stable contact of the conductive wire 4 and the conductive assembly 3.
[0054] As shown in Figure 2 and Figure 6 , the second plug-in part 31 includes a through hole 311 and a flange 312, and the flange 312 is formed around the through hole 311. The first plug-in part 11 can pass through the through hole 311 and interfere with the flange 312.
[0055] In the embodiment, the first plug-in part 11 and the flange 312 adopt interference fit, which realizes tight fixing through the friction between materials, effectively preventing connection loosening or accidental separation. The flange 312 structure wraps around the periphery of the through hole 311, which can guide the first plug-in part 11 to quickly align and insert, simplifying the installation operation. At the same time, the flange 312 increases the contact area, making the stress distribution more uniform, thereby improving the overall structural strength of the connection.
[0056] In the embodiment, the flange 312 is arranged around the periphery of the through hole 311 to form a circular truncated cone structure. The tapered structure of the circular truncated cone flange 312 makes the contact pressure distribute along the radial gradient, and the peak stress is reduced.
[0057] As shown in Figure 2 and Figure 6As shown, at least one gap 313 is formed on the flange 312.
[0058] In this embodiment, the gap 313 on the flange 312 is arranged axially along the flange 312, so that the flange 312 is more easily elastically deformed when the interference fit is made, reducing the axial force required for the insertion of the first plug-in part 11 and improving the assembly efficiency. At the same time, the gap 313 segments the flange 312, so that each region independently adapts to the shape of the first plug-in part 11, avoiding local stress concentration and improving the connection stability.
[0059] In this embodiment, the axial arrangement of the gap 313 enables the flange 312 to have the ability of self-resetting deformation, continuously maintaining the clamping force. After the interference insertion of the first plug-in part 11, the flange 312 can rebound to clamp the first plug-in part 11, avoiding the damage to the conductive assembly 3 caused by the "rigid constraint" of the traditional interference connection.
[0060] As shown in Figure 4 and Figure 5 , the first plug-in part 11 is a hollow cylindrical structure, and a cavity 111 is formed inside the first plug-in part 11, and one end of the conductive wire 4 is arranged in the cavity 111.
[0061] In this embodiment, the conductive wire 4 is arranged in the cavity 111 of the first plug-in part 11, which can avoid mechanical collision with other components and improve the service life of the conductive wire 4. At the same time, the conductive wire 4 is directly arranged through the pre-formed cavity 111, and the cavity 111 forms a radial constraint on the conductive wire 4, without the need for additional fixing devices (such as wire clamps or tapes) to prevent the wire from loosening due to vibration or pulling in long-term use.
[0062] As shown in Figure 2 and Figure 4 , the first plug-in part 11 is formed with a groove 112 at the end, and the cavity 111 is in communication with the groove 112; at least part of the conductive wire 4 is located in the groove 112.
[0063] The groove 112 structure provides a clear installation positioning point for the conductive wire 4, ensuring the accurate position of the conductive wire 4 in the cavity 111 and avoiding poor contact due to deviation.
[0064] In this embodiment, the design that the groove 112 is in communication with the cavity 111 enables the conductive wire 4 to naturally extend to the end of the first plug-in part 11, reducing the bending or twisting of the conductive wire 4 and reducing the risk of damage to the conductive wire 4 caused by mechanical stress.
[0065] As shown in Figure 1 , Figure 2 and Figure 5 , the socket cover 1 is also formed with a reinforcing member 5, and the reinforcing member 5 is connected between the first plug-in part 11 and the socket cover 1.
[0066] The reinforcing member 5 directly connects the first plug-in part 11 and the socket cover 1 in this embodiment, forming a triangular support structure that effectively disperses the axial and radial stress generated during the plug-in process, preventing the root of the first plug-in part 11 from breaking due to repeated plugging or external force impact.
[0067] In this embodiment, the reinforcing member 5, the socket cover 1, and the first plug-in part 11 are integrally formed. The integrated design eliminates the interface between components, the material distribution is continuous and uniform, significantly enhancing the overall torsional, bending, and tensile resistance, especially suitable for high-frequency plugging or vibration scenarios.
[0068] Further, in this embodiment, the first plug-in part 11 is made of insulating material. The insulating material blocks the current path between the first plug-in part 11 and the external environment or adjacent metal components, effectively preventing short circuit, electric shock, or accidental electric shock risk, improving equipment safety.
[0069] In this embodiment, the insulating material can be made of materials such as plastic, rubber, etc., which have the advantages of corrosion resistance, moisture resistance, etc., can avoid performance degradation of the first plug-in part 11 due to environmental factors, and prolong the service life. During the plugging process, the insulating material reduces the risk of direct contact between conductive components, suppresses the generation of electric arc or spark, reduces the fire hazard, especially suitable for high-voltage scenarios. Preferably, ceramic materials can also be used, which have excellent high-temperature resistance and can prevent the first plug-in part 11 from deforming or failing due to long-term work heating, improving equipment reliability.
[0070] Further, in this embodiment, the second plug-in part 31 and the conductive assembly 3 are integrally formed.
[0071] The integral molding eliminates the interface between the second plug-in part 31 and the conductive assembly 3, making the joint between the second plug-in part 31 and the conductive assembly 3 free of weak points, significantly enhancing the overall torsional, bending, and impact resistance. At the same time, the material continuity reduces the contact resistance, improving the electrical connection stability. Since there is no need to separately manufacture the second plug-in part 31 and subsequent welding or assembly steps, the tool clamps and manual operations are reduced, reducing production costs and time.
[0072] In summary, the specific assembly process of the indicator light 2 is as follows:
[0073] The conductive assembly 3 is fixed to the designated side of the socket cover 1 (corresponding to the installation side of the indicator light 2) by screws or buckles. One end of the conductive wire 4 is welded or crimped to the input end of the indicator light 2, and the other end is stripped of the appropriate length of insulation. The stripped conductive wire 4 is arranged along the pre-set wire path inside the socket cover 1 to the vicinity of the conductive assembly 3. The unconnected end of the conductive wire 4 is inserted into the cavity 111 of the first plug-in part 11 through the groove 112, and enough length of the conductive wire 4 is ensured. The first plug-in part 11 is vertically inserted into the through hole 311 of the second plug-in part 31, and appropriate pressure is applied to the end of the first plug-in part 11 to expose it from the flange 312.
[0074] Check that the conductive wire 4 is evenly clamped between the connectors without offset or extrusion damage. Turn off the external power supply and use a multimeter to test the conduction between the conductive assembly 3 and the indicator light 2. Turn on the power to test whether the indicator light is normally lit, and complete the assembly after confirming that there is no contact failure or short circuit phenomenon.
[0075] Example Two
[0076] This example is similar to Example One. For the same parts, refer to Example One. Only the improved parts will be described below.
[0077] As shown in Figure 7 and Figure 8 To prevent the first connector 11 from accidentally falling off due to vibration or external force, the end of the first connector 11 in this example also forms a limiting piece 113. After the first connector 11 is inserted into the second connector 31, the limiting piece 113 abuts against the flange 312. The abutment of the limiting piece 113 and the flange 312 forms a physical barrier, which cooperates with the interference fit to further improve the connection reliability.
[0078] Specifically, as shown in Figure 8 The limiting piece 113 is a protruding structure extending in the radial direction of the first connector 11. Since the flange 312 has at least one gap 313 formed therein, the flange 312 has a certain elastic deformation space, so that the limiting piece 113 can penetrate the circular truncated cone-shaped flange 312 and abut against the end of the flange 312 away from the through hole 311. In turn, the limiting piece 113 shares part of the fixing function, which can appropriately reduce the strict requirement for the interference amount, reduce the risk of material deformation, and prolong the service life of the first connector 11. When the limiting piece 113 abuts against the flange 312, tactile or visual feedback is provided, directly confirming that the first connector 11 has been completely inserted into position, avoiding poor contact caused by incomplete insertion.
[0079] Example Three
[0080] This example proposes a socket structure using the indicator light connection structure of Example One or Example Two.
[0081] The socket structure includes a main housing, a socket cover 1, an indicator light 2, and a conductive assembly 3. The main housing is made of flame-retardant engineering plastic and is injection molded. The surface is provided with a heat dissipation grille and a dust screen cover. The socket cover 1 and the main housing are quickly opened and closed through a clamping structure. The conductive assembly 3 and the conductive wire 4 are integrated inside, with compact layout.
[0082] In this example, the indicator light 2 and the conductive assembly 3 are designed as independent modules through the insertion structure of the first connector 11 and the second connector 31. When the indicator light is damaged, the entire socket does not need to be disassembled. Only the external power supply needs to be turned off, the socket cover 1 is opened, and the indicator light module is directly plugged in and replaced,
[0083] The conductive wire 4 directly realizes the electrical contact through the clamping action of the first plug-in part 11 and the second plug-in part 31, without welding or complicated wiring operation, significantly shortening the assembly time and reducing the risk of human operation failure. At the same time, the edge of the first plug-in part 11 avoids scratching the surface of the conductive assembly 3, eliminates the fatigue of the conductive assembly 3 caused by micro scratches and stress concentration, and prolongs the service life of the conductive assembly 3.

The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent flow transformation using the content of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
