Description

Technical Field

[0001] The utility model relates to the technical field of indicator light installation, in particular to an indicator light structure. Background Art

[0002] The charger indicator light can display the working status of the charger when the charger is working. The head of the indicator light connected to the charger circuit board is located in the hole of the charger housing, which is convenient for the user to observe the status of the indicator light. Some indicator lights have a pointed head and a flange at the tail. The flange contacts the charger housing, which is convenient for positioning the indicator light when it is installed. The pin is led out from the tail of the indicator light and connected to the circuit board. The existing charger indicator light is directly plugged into the circular hole of the charger housing. However, the indicator light lacks a limit in the direction of the inside of the housing. The head of the indicator light is easy to move into the housing after being impacted, which makes it inconvenient to observe the working status of the indicator light when the charger is working. In order to solve this technical problem, it is generally necessary to add a process of gluing the indicator light to the charger housing during the charger assembly process, which reduces the assembly efficiency of the charger.

[0003] Some chargers have a transparent protective cover fixed inside the hole for mounting the indicator light. This effectively prevents the indicator light from being squeezed into the charger housing, but adding the protective cover increases the production process and cost of the charger housing. Furthermore, installing the protective cover inside the hole in the charger housing requires either a corresponding cavity to be provided inside the charger housing to mount the indicator light, or the indicator light must be glued to the protective cover. This increases the production cost of the charger housing and complicates assembly.

[0004] Patent document CN216751260U discloses a split-type charger, wherein a charging status indicator light is provided above the protective shell, a card slot is provided above the charging status indicator light, a hanging hole is provided above the card slot, a positioning groove is provided below the hanging hole, a charging head is provided above the positioning groove, a plug socket is provided behind the charging head, a plug is provided above the plug socket, a socket end is provided above the plug, a diode is provided inside the socket end, a circuit board is provided below the diode, and a converter is provided above the circuit board. The indicator light of this charger is directly plugged into the hole of the protective shell, so when the indicator light is squeezed, it is easy to move toward the inside of the protective shell, affecting the user's observation of the indicator light's working status.

[0005] Patent document CN204559150U discloses a novel timed charger, wherein the charging indicator light is an LED light, which is connected to a control circuit board, and the bulb of the charging indicator light is adapted to the charging light-emitting through hole of the housing body; the first timed indicator light is an LED light, which is connected to the control circuit board, and the bulb of the first timed indicator light is adapted to the first timed light-emitting through hole of the housing body; the second timed indicator light is an LED light, which is connected to the control circuit board, and the bulb of the second timed indicator light is adapted to the second timed light-emitting through hole of the housing body; the third timed indicator light is an LED light, which is connected to the control circuit board, and the bulb of the third timed indicator light is adapted to the third timed light-emitting through hole of the housing body; the fourth timed indicator light is an LED light, which is connected to the control circuit board, and the bulb of the fourth timed indicator light is adapted to the fourth timed light-emitting through hole of the housing body; the fifth timed indicator light is an LED light, which is connected to the control circuit board, and the bulb of the fifth timed indicator light is adapted to the fifth timed light-emitting through hole of the housing body. This technical solution also lacks components for limiting the installation of the indicator lights. Utility Model Content

[0006] The main purpose of the utility model is to provide an indicator light structure which is easy to install, has good stability, can facilitate the assembly of the charger, reduce the assembly cost of the charger and improve the assembly efficiency.

[0007] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0008] An indicator light structure includes a shell, a through hole for installing the indicator light is opened on one side of the shell, the head of the indicator light is arc-shaped, the tail of the indicator light is processed with a flange, and a limit assembly corresponding to the through hole is fixed in the shell, the limit assembly includes two side plates fixed in the shell, the through hole is located between the two side plates, and the ends of the two side plates away from the shell are fixedly connected by a baffle, the height of the upper end of the baffle is less than the height of the upper end of the side plate, and a groove is opened on the side of the upper end of the side plate close to the baffle, and the height of the bottom of the groove is less than the height of the upper end of the baffle.

[0009] Specifically, the baffle, side panels and shell are integrally formed.

[0010] Specifically, the diameter of the through hole is smaller than the diameter of the indicator light.

[0011] Specifically, the distance between the baffle and the opposite end surface of the inner wall of the housing is smaller than the length of the indicator light.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. By arranging side panels, baffles and grooves in the housing, when the indicator light is installed, the lower end of the flange on the indicator light is clamped in the groove, so that the head of the indicator light is located in the through hole. Since the diameter of the through hole is smaller than the diameter of the indicator light and the distance between the opposite end faces of the baffle and the inner wall of the housing is smaller than the length of the indicator light, the head end of the indicator light can be clamped in the through hole. At this time, under the blocking effect of the baffle on the tail end of the indicator light and the blocking effect of the housing on the head end of the indicator light, the indicator light is clamped between the baffle and the housing, which can effectively ensure the stable performance of the connection between the indicator light and the housing.

[0014] 2. After the indicator light is installed, there is no need to use adhesive to fix it, which can improve the assembly efficiency of the charger.

[0015] 3. When the indicator light portion in the through hole is squeezed into the housing, the indicator light can be prevented from moving into the housing under the blocking effect of the baffle, and the positioning effect of the indicator light is good.

[0016] 4. No protective cover is required in the through hole of the shell, which can reduce the production cost of the shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1-4As shown, an indicator light structure includes a shell 1, a through hole 2 for installing the indicator light is opened on one side of the shell 1, and the diameter of the through hole 2 is smaller than the diameter of the indicator light. The head of the indicator light is arc-shaped, and the tail of the indicator light is processed with a flange. A limit assembly corresponding to the through hole 2 is fixed in the shell 1, and the limit assembly includes two side plates 3 fixed in the shell 1. The through hole 2 is located between the two side plates 3. The ends of the two side plates 3 away from the shell 1 are fixedly connected by a baffle 5, and the height of the upper end of the baffle 5 is less than the height of the upper end of the side plate 3. The distance between the baffle 5 and the opposite end face of the inner wall of the shell 1 is less than the length of the indicator light. A groove 4 is opened on the side of the upper end of the side plate 3 close to the baffle 5, and the height of the bottom of the groove 4 is less than the height of the upper end of the baffle 5. The baffle 5, side plate 3 and shell 1 are formed as one piece.

[0024] When installing the indicator light, the indicator head is tilted upward, the lower end of the flange at the rear of the indicator light snapping into groove 4, and the indicator head is then pressed into position within through-hole 2. Because the diameter of through-hole 2 is smaller than the diameter of the indicator light, and the distance between the opposing end surfaces of baffle 5 and the inner wall of housing 1 is less than the length of the indicator light, the head of the indicator light can be retained within through-hole 2. At this point, with baffle 5 blocking the rear end of the indicator light and housing 1 blocking the head of the indicator light, the indicator light is held between baffle 5 and housing 1, effectively ensuring a stable connection between the indicator light and housing 1.

[0025] After installation, the indicator light does not require adhesive bonding, improving charger assembly efficiency. When the indicator light portion within through-hole 2 is pressed into housing 1, the baffle 5 prevents the indicator light from moving into housing 1, effectively positioning the indicator light. No protective cover is required within through-hole 2 of housing 1, reducing the production cost of housing 1.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
