The mobile socket is a socket which can move freely according to the use requirement, and is a common electrical accessory. An indicator light is usually arranged on the socket, and whether the movable socket is communicated with a power supply or not can be known by observing the indicator light. Can directly assemble the pilot lamp of portable socket on portable socket panel at present, however, because can remove portable socket position often in the use, can rock even, long-term the back of using, the pilot lamp of assembly on portable socket panel probably drops from portable socket panel, if directly adopt modes such as welding, adhesion to fix the pilot lamp on the panel of socket, then assembly efficiency is low and hardly change when the pilot lamp damages.

Therefore, there is a need for an improved mounting structure for an indicator light that is reliably mounted on a receptacle panel to prevent the above-mentioned consequences.

In view of the above problems, the present embodiment provides a mobile socket with an indicator light, as shown in fig. 1 to 3, including a housing 1 and an indicator light 2, where the housing 1 is provided with a through hole 11, the indicator light 2 is disposed in the through hole 11, the inner wall of the through hole 11 is provided with a protruding limiting portion 3, and the limiting portion 3 is located on one side of the indicator light 2 close to the inside of the housing 1; the minimum radial dimension of the through hole 11 at the limiting part 3 is smaller than the dimension of the indicator light 2 in the radial direction; the stopper portion 3 is made of a material having elastic deformation capability, and can be elastically deformed in the radial direction when being pressed.

The through hole 11 may be a cylindrical hole, a prismatic hole or a special-shaped cylindrical hole, when the through hole 11 is a prismatic hole or a special-shaped cylindrical hole, the axis of the through hole 11 is the center line of the through hole 11, and the radial direction of the through hole 11 refers to a direction corresponding to any straight line which is perpendicular to the center line of the through hole 11 and passes through the center line.

The indicator light 2 is a neon light or an LED light; the shape of the indicator lamp 2 may or may not correspond to the shape of the through hole 11, as long as the indicator lamp 2 can be securely fitted into the through hole 11.

The shape of the indicator light 2 corresponds to the shape of the through hole 11, that is, the cross-sectional shape of the indicator light 2 in the direction perpendicular to the axis of the through hole 11 is the same as the cross-sectional shape of the through hole 11 in the direction but different in size, for example, when the through hole 11 is a cylindrical hole, the indicator light 2 is also a cylindrical lamp post, but the diameter of the indicator light 2 is smaller than that of the through hole 11, so that the indicator light 2 can be fitted into the through hole 11. Accordingly, the shape of the indicator lamp 2 does not correspond to the shape of the through hole 11, meaning that the cross-sectional shape of the indicator lamp 2 in the direction perpendicular to the axis of the through hole 11 is different from the cross-sectional shape of the through hole 11 in that direction, for example, when the through hole 11 is a cylindrical hole, the indicator lamp 2 may be a prism-shaped lamp post or other shaped lamp post as long as it is ensured that the indicator lamp 2 can be fitted into the through hole 11.

One side inside the shell 1 refers to the side inside the socket after the shell 1 is assembled into the socket, and one side inside the shell 1 cannot be directly seen in the using process of the socket and is used for accommodating elements inside the socket; the outer side of the housing 1 refers to the side of the housing 1 located outside the socket after the socket is assembled, and the outer side of the housing 1 is exposed to the outside during the use of the socket and can be directly seen by a user. When the through-hole 11 is provided on different walls of the housing 1, the axial direction thereof may be different, but the through-hole 11 always communicates the inside side and the outside side of the housing 1.

For example, as shown in fig. 3, the side indicated by O is the outer side of the housing 1, and the side indicated by I is the inner side of the housing 1. The outside one side of casing 1 that is equipped with through-hole 11 is the panel of portable socket generally, and when portable socket was used, portable socket's panel faced the user, and the user observes the state of pilot lamp 2 through-hole 11, alright know portable socket and whether with the power intercommunication.

Spacing portion 3 can be elastic construction spare, its self can take place deformation, thereby make through-hole 11 at the radial dimension grow of spacing portion 3 department, make pilot lamp 2 can assemble in through-hole 11, for example, refer to fig. 3, spacing portion 3 can be platelike or banding structure spare, its one end is fixed at through-hole 11 lateral wall, the other end is the free end, or the other end adopts modes such as shell fragment or pressure spring to be connected with through-hole 11 lateral wall, make spacing portion 3 when receiving the extrusion, its self can produce deformation and resume former shape when the extrusion force is removed. As shown in FIG. 3, the minimum radial dimension L of the through-hole 11 at the stopper portion 3 _min Is generally slightly smaller than the dimension D, L, of the indicator light 2 in the radial direction _min <D, in the course of production, L _min Is determined by the elastic deformation ability of the limiting part 3, in order to ensure that the indicator lamp 2 can smoothly pass through the limiting part 3, and after the indicator lamp 2 passes through the limiting part 3, the limiting part 3 can block the indicator lamp 2 from falling off from one side of the inside of the shell 1, for the indicator lamp 2 with fixed size, if the elastic modulus of the limiting part 3 is large, after the indication is extruded, the limiting part 3 can generate large deformation for indicating the indicator lamp 2 to pass through the through hole 11, therefore, in order to more surely block the indicator lamp 2, the indicator lamp 2 is prevented from falling off, D and L _min The difference of (a) can be set to be large; correspondingly, if the elastic modulus of the limiting member 3 is small, it means that after being squeezed, the limiting member 3 can generate small deformation for the indicator 2 to pass through the through hole 11, and in order to ensure that the indicator 2 smoothly passes through the through hole 11, D and L _min The difference of (a) can be set smaller.

Referring to fig. 3, the bottom side of the through hole 11 is the inside of the housing 1, when the indicator light 2 is assembled, the indicator light 2 is pushed upwards from the bottom side of the through hole 11, the indicator light 2 extrudes the limiting portion 3, so that the limiting portion 3 deforms, the radial size of the through hole 11 at the position becomes larger, the indicator light 2 continues to be pushed in, until the indicator light 2 is installed in the through hole 11 through the limiting portion 3, the deformation of the limiting portion 3 is recovered, the limiting portion 3 becomes the blocking of the indicator light 2 falling to the inside of the housing 1, and therefore the reliable installation of the indicator light 2 in the through hole 11 can be realized through the limiting portion 3, and the installation is simple and rapid, and the efficiency is high. And, because fixed connection such as welding or adhesion is not carried out between pilot lamp 2 and the casing 1, so when pilot lamp 2 damages, need not to change casing 1, but through making spacing portion 3 warp in the footpath of through-hole 11 for pilot lamp 2 in the embodiment of this application dismantles from casing 1 easily, and only need directly with the pilot lamp 2 of damage replace can, made things convenient for the change of pilot lamp 2.

As shown in fig. 3, in some embodiments, the limiting part 3 includes a transition surface 31 and a first limiting surface 32, the first limiting surface 32 is located on one side of the limiting part 3 close to the indicator light 2, and the transition surface 31 is located on one side of the limiting part 3 close to the inside of the housing 1; the transition surface 31 is inclined in a direction from the inside of the housing 1 to the outside of the housing 1 toward the axis of the through-hole 11.

As shown in fig. 3, in some embodiments, the transition surface 31 may be a smooth flat surface, and in other embodiments, the transition surface 31 may also be a smooth curved surface, so as to facilitate the indicator light 2 to smoothly pass through the limiting portion 3. The indicator light 2 can slide along the transition surface 31 towards the inside of the through hole 11, and the transition surface 31 mainly functions to provide a smooth transition for the indicator light 2 to be assembled from one side of the inside of the shell 1 to the deep inside of the through hole 11.

As shown in fig. 3, the first limiting surface 32 may be a plane, the first limiting surface 32 is opposite to the bottom surface of the indicator light 2, and the first limiting surface 32 and the transition surface 31 may be two adjacent surfaces or two surfaces that are not adjacent to each other, for example, fig. 3 shows a case where the first limiting surface 32 is adjacent to the transition surface 31, and fig. 4 shows a case where the first limiting surface 32 is not adjacent to the transition surface 31. The radial dimension of the through hole 11 at the first stopper surface 32 is minimized so that the indicator lamp 2 cannot be dropped downward (toward the inside of the housing 1) from this position.

By adopting the scheme, when the indicator lamp 2 is assembled in the through hole 11, the indicator lamp 2 is stressed, the outer surface of the indicator lamp 2 abuts against the transition surface 31 and slides from the surface of the transition surface, the indicator lamp 2 gradually slides towards the inside of the through hole 11 along the inner wall of the through hole 11 until the indicator lamp passes through the first limiting surface 32 and then is assembled in the through hole 11, so that the transition surface 31 is more favorable for assembling the indicator lamp 2, and the assembling efficiency is improved; the first limiting surface 32 can block the indicator light 2 from moving towards one side inside the housing 1, so that the situation that the indicator light 2 falls off towards the inside of the housing 1 can be reduced and prevented.

In some embodiments, as shown in fig. 3 to 5, the inner wall of the housing 1 is provided with the mounting block 4, the through hole 11 penetrates through the wall of the housing 1 and the mounting block 4, the through hole 11 includes a first hole section penetrating through the housing 1 and a second hole section penetrating through the mounting block 4, and the limiting part 3 is disposed on the inner wall of the second hole section; the second hole segment is further provided with a slot 41, and the slot 41 penetrates through the side wall of the second hole segment.

Based on above-mentioned structure, when pilot lamp 2 extrudes spacing portion 3, spacing portion 3 not only can make pilot lamp 2 pass through the elastic deformation of self, can also make spacing portion 3 drive the lateral wall of second hole section and take place elastic deformation together to make the radial dimension grow of second hole section, in order to supply pilot lamp 2 to pass through. For example, as shown in fig. 4 and 5, the limiting portion 3 and the mounting block 4 may be integrally formed plastic, or the limiting portion 3 is connected to the mounting block 4 by a fixing method such as adhesion. Thus, when the indicator lamp 2 presses the limiting part 3, the connecting part of the mounting block 4 and the limiting part 3 is also stressed and deformed, so that the radial dimension of the through hole 11 at the limiting part 3 is increased.

In the present embodiment, the through hole 11 is a hole penetrating through the mounting block 4 from the outside of the housing 1 to the inside of the housing 1, and therefore, the side wall of the through hole 11 is mainly composed of two sections, i.e., a side wall at the first hole section of the housing 1 and a side wall at the second hole section of the mounting block 4.

The installation piece 4 makes the length of through-hole 11 increase, and the through-hole 11 is more firm with the mounting structure of pilot lamp 2 to the convenience sets up spacing portion 3 on the through-hole 11 inner wall.

Through set up slotted hole 41 on the second hole section for the rigidity of installation piece 4 reduces, and the lateral wall of second hole section reduces spacing portion 3's holding power, so when pilot lamp 2 extrudes spacing portion 3, installation piece 4 produces deformation along with spacing portion 3 more easily, also can be more laborsaving during the assembly pilot lamp 2.

As shown in fig. 6, in some embodiments, the inner wall of the second hole segment is opened with a break groove 44 on both sides of the limiting part 3 along the circumferential direction of the through hole 11, and the break groove 44 is communicated with the groove hole 41.

When the through hole 11 is a cylindrical hole, the circumferential direction of the through hole 11 refers to the circumferential direction of the through hole 11; when the through-hole 11 is a prismatic hole or a polygonal columnar hole, the circumferential direction of the through-hole 11 refers to a direction perpendicular to the axis of the through-hole 11 along the side wall of the through-hole 11.

In-process of pilot lamp 2 to assembly in the through-hole 11, when pilot lamp 2 located through spacing portion 3, deformation took place to the direction of keeping away from the axis of through-hole 11 for spacing portion 3, when not setting up disconnected groove 44, spacing portion 3 was held down by the internal stress of installation piece 4, so deformability is less, and set up disconnected fluting back, disconnected groove 44 can further reduce the rigidity of installation piece 4, and make spacing portion 3 and slotted hole 41 adjacent one side, and spacing portion 3 all can not be held down by installation piece 4 with disconnected groove 44 adjacent one side, make the assembly of pilot lamp 2 more laborsaving, thereby further improve the assembly efficiency of pilot lamp 2.

As shown in fig. 4 to 7, in some embodiments, the inner wall of the through hole 11 is further provided with a plurality of protruding first ribs 42, and the plurality of first ribs 42 are arranged along the circumferential direction of the through hole 11 and are respectively abutted against the indicator lamp 2.

The first rib parts 42 are arranged along the circumferential direction of the through hole 11 and are respectively abutted against the indicator light 2, which means that the contact part of the first rib part 42 and the indicator light 2 is generated on the outer circumferential surface of the indicator light 2, and the contact mode of the first rib part 42 and the indicator light 2 can be point contact, line contact or surface contact.

In some embodiments, the first rib 42 may be configured as an elongated protrusion parallel to the axis of the through hole 11, and the first ribs 42 may be set to different sizes, or may be set to the same size, as long as the first ribs 42 abut against the indicator light 2 at different positions in the circumferential direction of the indicator light 2, so as to limit the position of the indicator light 2.

As a commonly used electrical equipment, the movable socket is frequently moved in use, violent movements such as shaking and vibration can be generated in the movement, in the process, the indicator lamp 2 can collide with the side wall of the through hole 11, the indicator lamp 2 is limited at different positions of the plurality of first rib parts 42 in the circumferential direction of the indicator lamp 2, the condition that the indicator lamp 2 collides with the side wall of the through hole 11 severely due to the fact that the indicator lamp 2 has a large movement amplitude in the through hole 11 is avoided, and the indicator lamp 2 is protected.

As shown in fig. 4, 5 and 7, in some embodiments, the first rib 42 includes a first guide surface 422 disposed along the axial direction of the through hole 11, and the first rib 42 is brought into surface contact with the indicator lamp 2 by the first guide surface 422 being engaged with the indicator lamp 2.

By adopting the above scheme, on one hand, referring to fig. 5, the first rib part 42 is in surface contact with the indicator light 2, so that the contact area between the first rib part 42 and the indicator light 2 is increased, the indicator light 2 is prevented from being broken by the first rib part 42, and the protective effect of the first rib part 42 on the indicator light 2 is enhanced; on the other hand, when the indicator light 2 is assembled into the through hole 11, although one side of the outer peripheral wall of the indicator light 2 is inclined due to the abutting of the limiting part 3, the indicator light 2 is gradually abutted by the first guide surfaces 422 of the plurality of first ribs 42 in the circumferential direction along with the further assembly of the indicator light 2 after the indicator light 2 is contacted with the first guide surfaces 422 and slides into the through hole 11 along with the further sliding of the indicator light 2, and in the process, the first guide surfaces 422 play a role in guiding the indicator light 2, so that the deflection phenomenon after the indicator light 2 is assembled is avoided.

As shown in fig. 5, in some embodiments, the indicator light 2 includes a lamp post 21 and a flange 22 located on a side of the lamp post 21 adjacent to the interior of the housing 1; the first rib 42 further comprises a second limiting surface 421, and the second limiting surface 421 is located on one side of the first rib 42 close to the inside of the housing 1; the flange 22 is located between the first stopper surface 32 and the second stopper surface 421 in the axial direction of the through hole 11.

The flange 22 may be a whole ring structure protruding from the outer peripheral surface of the lamp post 21, or may be a plurality of protruding blocks protruding from the outer peripheral surface of the lamp post 21, and the protruding blocks are directly opposite to the first rib portion 42 or the limiting portion 3 along the axial direction of the through hole 11.

The fact that the flange 22 is located between the first limiting surface 32 and the second limiting surface 421 means that the flange 22 is located between a spatial plane where the first limiting surface 32 is located and a spatial plane where the second limiting surface 421 is located, rather than that the first limiting surface 32 and the second limiting surface 421 are opposite to each other in the axial direction of the through hole 11, and the flange 22 is located at an opposite position of the first limiting surface 32 and the second limiting surface 421.

By adopting the above-described configuration, both sides of the flange 22 in the axial direction of the through hole 11 are restricted between the second stopper surface 421 and the first stopper surface 32, so that the indicator lamp 2 is reliably restricted within the through hole 11, and is not only hard to come out from the inner side of the housing 1 under the restriction of the first stopper surface 32, but also hard to come out from the outer side of the housing 1 under the restriction of the second stopper surface 421.

As shown in fig. 5 and 7, in some embodiments, the inner wall of the through hole 11 further includes a second protruding rib 43, the second rib 43 is located on the opposite side of the limiting portion 3, and the second rib 43 includes a second guide surface 431; the second guide surface 431 faces the outer periphery of the flange 22, and the shortest distance between the second guide surface 431 and the stopper portion 3 is smaller than the dimension of the flange 22 in the shortest distance direction.

By adopting the above scheme, on one hand, as shown in fig. 5, the first limiting surface 32 and the second limiting surface 421 are not on the same horizontal plane, if the through hole 11 has a large size in the circumferential direction of the flange 22, the indicator lamp 2 installed in the through hole 11 may fall off from the through hole 11, especially under the working conditions of long-term vibration, movement and the like of the socket, in order to avoid this, the second guide surface 431 is arranged at the opposite position of the limiting part 3 to limit the movement of the flange 22 of the indicator lamp 2 in the radial direction, and avoid the flange 22 from separating from the first limiting surface 32 of the limiting part 3, thereby further preventing the indicator lamp 2 from falling off after being assembled; on the other hand, when the indicator light 2 is assembled to the through hole 11, in the process that one side of the flange 22 abuts against the limiting part 3 and gradually slides, the other side of the flange 22 can also abut against and slide with the second guide surface 431, and in the process, the second guide surface 431 plays a role in guiding the flange 22, so that the flange 22 can continuously extrude the limiting part 3 to deform the limiting part and give way for the space for the flange 22 to enter, and the smooth assembly process of the indicator light 2 is ensured; in addition, under the working environment such as carrying, rocking, portable socket can restrict the radial motion of flange 22 in through-hole 11 through the contact of second guiding surface 431 of second muscle portion 43 with the periphery wall of flange 22, further prevents that pilot lamp 2 from having the collision of great amplitude in through-hole 11, avoids pilot lamp 2 to damage and pilot lamp 2 circuit to damage to strengthen the guard action to pilot lamp 2.

The indicator light 2 in some existing sockets is fixed on a circuit board in a welding mode, meanwhile, electrodes are welded on the circuit board, and electrification is achieved through contact between the circuit board and the electrodes, but when the indicator light 2 is welded on the circuit board, the defects of high welding difficulty, welding slag generation and the like exist, and the circuit in the socket can be possibly influenced.

The elastic member 5 may be a spring or a leaf spring. When the elastic member 5 is a spring, the spring may be a cylindrical spring or a torsion spring, and the power supply circuit 7 is abutted against the cylindrical spring by compressing the cylindrical spring in the length direction, or the power supply circuit 7 is compressed by abutting against the legs of the torsion spring. When the elastic member 5 is a spring plate, the spring plate may be a U-shaped spring plate or any spring plate that is bent in a natural state, and the power supply circuit 7 compresses the spring plate by pressing one end of the leg of the spring plate. Fig. 8 is schematically illustrated only by way of example of the power supply circuit 7 compressing a cylindrical spring. The power supply circuit 7 includes a conductive plate having a certain rigidity, and the power supply circuit 7 is generally used for connecting with the N pole and the L pole of the power supply to take a point from the power supply, so that when the electric device is inserted into the socket of the socket, electricity can be obtained from the socket. The indicating lamp 2 in the embodiment is in circuit connection with the power supply circuit 7 through the abutting joint of the elastic piece 5 and the power supply circuit 7, wherein the elastic piece 5 generates elastic force after being compressed, and the abutting joint of the elastic piece and the power supply circuit 7 is tighter under the action of the elastic force, so that when the indicating lamp 2 in the embodiment is installed on a movable socket, the lead 6 of the indicating lamp 2 can be stably and electrically connected with the power supply circuit 7; in addition, elastic component 5 is connected through the mode electricity of butt with supply circuit 7, and supply circuit 7 is nimble changeable to elastic component 5's compression degree, does not receive the restriction of space and part machining size for the assembly of pilot lamp 2 is simpler, has avoided the technological degree of difficulty that brings pilot lamp 2 wire 6 and supply circuit 7 welding.

In some embodiments, the resilient member 5 is riveted to the wire 6, as shown in fig. 9.
