Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a locomotive irradiation lamp and an adaptor power connector thereof. Background Art

[0002] The old Harmony electric locomotives use tungsten filament lamps for lighting, and their lighting brightness and lighting distance can no longer meet the actual needs of locomotive use. Therefore, it is necessary to transform the lamps. The transformation plan uses LED lighting technology, which can significantly increase the lighting brightness and improve the effective lighting distance. However, in order to increase the effective illumination distance of the light, this technical transformation plan generally deepens the depth of the lampshade. The height of the lamp after the technical transformation is significantly higher than that of the original design lamp, which makes the installation space redundant after the irradiation lamp is inserted into the power connector, resulting in the power wire needing to be deeply bent or even unable to be installed; at the same time, the processes used in the manufacturing of various types of locomotives are different. Depending on the vehicle number, the gap between the installation position of the irradiation lamp on the vehicle body is also different, which has a certain impact on the batch maintenance work of the locomotive. The irradiation lamps in the prior art are generally of bowl-shaped design, and the power connector protection rubber body generally protrudes from the bottom of the bowl. The installation height is the height of the irradiation lamp bowl plus the height of the power connector and the height of the cable extension space. The overall height cannot be reduced or modified. Therefore, it is necessary to design a compact irradiation lamp and an adapter power connector thereof to minimize the total height of the irradiation lamp after the power connector is plugged in.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only the best embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] This embodiment provides a locomotive irradiation lamp and its adaptor power connector, such as Figure 1-Figure 4 As shown, the irradiation lamp adopts LED lighting technology, which includes an LED lamp board 6, a reflective bowl 4 and a joint sealing seat 1. In order to increase the illumination distance, the height of the reflective bowl 4 is lengthened, and the LED lamp board 6 is arranged on the focusing center inside the reflective bowl 4. In order to reduce the total installation height of the irradiation lamp, the small end of the integrally formed bowl body 41 is concave to form a groove body 42, and the groove body 42 is located inside the bowl body 41. The idle area from the focusing center inside the reflective bowl 4 to its small end is used as the embedding and accommodating space of the joint sealing seat 1, and the joint sealing seat 1 is inserted into the groove body 42. This is a structural design for reducing the total installation height;

[0021] like Figure 3As shown, the outer plane of the groove body 42 can also be used as an installation platform for the LED light board 6. The LED light board 6 is electrically connected to the control board 17. The control board 17 is installed in the control board installation body 16. The control board installation body 16 is sealed and encapsulated in the joint sealing seat 1. The joint sealing seat 1 is also glued and fixed with a power plug 15 to form a joint slot 11. The power plug 15 is located at the bottom of the joint slot 11. The power plug 15 is electrically connected to the control board 17. The power connector 2 adapted to the irradiation lamp is inserted into the connector slot 11. The plug socket 26 provided on the power connector 2 corresponds to the position of the power plug 15. The two are plugged together to make the power wire 3 and the power plug 15 conductive. The power wire 3 is introduced laterally from the power connector 2 and is clamped in the power connector 2 by the flag-shaped terminal at its end. By eliminating the cable bending space required for the straight plug, the installation height required for the irradiation lamp is reduced. This is the second structural design for reducing the total installation height.

[0022] As a further technical solution, in order to facilitate the rapid installation of the power wire 3, a horizontal wire hole 25 is provided on the side of the power connector 2 for introducing the power wire 3, and the plug hole 26 is perpendicular to the wire hole 25, which extends from the bottom end of the power connector 2 to the wire hole 25. Figure 4 As shown, the power connector 2 is divided along the transverse diameter of the wire hole 25 to form an upper plug body 21 and a lower plug body 22. After the power wire 3 is placed and positioned in the semi-wire hole 25 of the lower plug body 22, since the plug-in hole 26 is a T-shaped structure, the flag-shaped terminal at the end of the power wire 3 is inserted into the plug-in hole 26 of the upper plug body 21, and the upper plug body 21 and the lower plug body 22 are quickly connected through the snap-fit ​​structure 23, and the power wire 3 is clamped inside the power connector 2.

[0023] As a further technical solution, since the power supply of the locomotive is generally a three-wire system, the number of the power wire 3, the power plug 15, the wire hole 25 and the plug hole 26 is three, so as to facilitate the rapid locking of the insertion position, such as Figure 1 , Figure 2 and Figure 4 As shown, the two side corners of the power connector 2 are limited female corners 24, and the corresponding hole corners of the connector slot 11 are plug-in limited male corners 13. At the same time, since the installation orientation of the power connector 2 is restricted, in order to adapt to the connection of power wires 3 in different orientations, the wire hole 25 on the power connector 2 runs through its two opposite side surfaces, and the power wire 3 can be introduced and installed from either side of the irradiation lamp as needed, which is suitable for the installation of the left and right irradiation lamps of the locomotive.

[0024] As a further technical solution, Figure 2As shown, the outer end surface of the connector sealing seat 1 is vertically milled to form a wire protection groove 14 running through both sides thereof. The groove width of the wire protection groove 14 is adapted to the surface width occupied by the three power lines, and the groove depth is based on at least completely enclosing the power wire 3. The power wire 3 is introduced into the side of the power connector 2 through the wire protection groove 14. The setting of the wire protection groove 14 can further protect the power wire 3 and, under the design of the same total installation height, increase the plug-in contact area and improve the plug-in stability.

[0025] As a further technical solution, Figure 4 As shown, the buckling structure 23 is located on both sides of the power connector 2, which includes a buckling protrusion located on the upper plug body 21 and a buckling piece located on the lower plug body 22. The buckling piece is higher than the upper end surface of the lower plug body 22, and is provided with a buckling hole adapted to the buckling protrusion. The end of the buckling piece and the adjacent end of the buckling protrusion are both wedge-shaped structures. Under the action of the vertical pressing force, the buckling piece can be elastically deformed to lock the buckling protrusion to complete the buckling connection. At the same time, in order to make way for the buckling structure 23 so that the power plug and the connector slot 11 can be better plugged and matched, both sides of the connector slot 11 are provided with a clearance groove 12 adapted to the buckling structure 23, as shown in FIG. Figure 1 As shown, the provision of the clearance groove 12 can further enhance the ability of the buckle structure 23 to withstand the lateral force of the power supply wire 3, thereby preventing the upper insert body 21 and the lower insert body 22 from being separated under the action of the lateral force.

[0026] As a further technical solution, in order to improve the heat dissipation capacity of the irradiation lamp, the power connector 2, the connector sealing seat 1, the control board mounting body 16 and the groove body 42 are all provided with heat dissipation holes 27, and the heat dissipation holes 27 of the four are mutually connected in sequence. Figure 3 As shown, one end of the heat dissipation hole 27 is connected to the hollow area of ​​the bottom plane of the LED lamp board 6. The front plane of the LED lamp board 6 is an LED particle lamp, and the middle part of it is a hollow area. The heat dissipation hole 27 is connected to the hollow area to form a heat dissipation channel.

[0027] As a further technical solution, in order to further protect the reflective bowl 4 and facilitate its installation, a circle of mounting rubber ring 5 is provided along the edge of the large end of the reflective bowl 4 .
