Description

Technical Field

[0001] The invention relates to an indicator light, in particular to an indicator light. Background Art

[0002] The existing indicator lights are divided into two types: anti-interference type and non-anti-interference type. When the user's use environment is poor and the electromagnetic interference is serious, even if the indicator light circuit is disconnected, an induced voltage will still be formed at both ends of the indicator light. Since the indicator lights use LED light-emitting elements, the lighting voltage threshold is generally only 5V. As long as the induced voltage above 5V is generated, the non-anti-interference indicator light will light up slightly, which will mislead the user. Therefore, these users need to choose anti-interference indicator lights.

[0003] Compared with the non-anti-interference indicator light, the anti-interference indicator light has an additional resistor connected in parallel in the internal circuit of the product, which can increase the lighting voltage threshold of the indicator light, such as 20V, 30V, 40V, etc., to achieve anti-interference effect.

[0004] However, some users are not sure whether their use environment will generate induced voltage, so they choose non-anti-interference products. After installation and use, they find that the indicator light is lit due to induced voltage. At this time, they can only remove the non-anti-interference indicator light and buy an anti-interference indicator light and replace it, which is easy to waste costs and delay the selection of lamps. Summary of the invention

[0005] In view of the shortcomings of the prior art, an object of the present invention is to provide an indicator light that can switch a non-interference-resistant indicator light to an interference-resistant indicator light to reduce the user's monetary cost.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an indicator light, comprising a shell, a light-emitting component arranged in the shell, a wiring component arranged in the shell, the light-emitting component being electrically connected to the wiring component, and also comprising an anti-interference accessory detachably mounted on the shell, the anti-interference accessory having a conductive plug-in, the wiring component being electrically connected to a contact, and when the anti-interference accessory is mounted on the shell, the plug-in and the contact cooperate to form a conductive contact, so as to electrically connect the anti-interference accessory to the contact through the plug-in.

[0007] As a further improvement of the present invention, the wiring assembly includes two wiring terminals respectively used to connect the live wire and the neutral wire or the positive pole and the negative pole, and the light-emitting assembly is electrically connected to the two wiring terminals to obtain power; both of the two wiring terminals have contacts, and the positions corresponding to the two contacts on the anti-interference accessory have plug-ins. When the light-emitting assembly is installed on the housing, the plug-in connector contacts the corresponding contact members for electrical conduction, so as to connect the anti-interference accessory in parallel to the two wiring terminals.

[0008] As a further improvement of the present invention, the contact piece is in a clamp structure and is used for inserting and clamping the connector.

[0009] As a further improvement of the present invention, the contact piece is formed by bending a conductive metal piece to form a clip structure, and one end of the clip structure corresponding to the anti-interference accessory is tilted to form an opening for inserting the connector, and the opening forms a guide slope through the tilting of the clip structure to guide the connector to be inserted into the clip structure and clamped.

[0010] As a further improvement of the present invention, the light emitting component is located at one end of the shell, the wiring component is located at the other end of the shell corresponding to the light emitting component, and the anti-interference accessory is detachably installed at the end of the shell corresponding to the wiring component.

[0011] As a further improvement of the present invention, the side edge shape of the anti-interference accessory corresponds to one end of the shell corresponding to the anti-interference accessory.

[0012] As a further improvement of the present invention, the anti-interference accessory is detachably connected to the housing via a snap-on structure.

[0013] As a further improvement of the present invention, a buckle is provided on the anti-interference accessory, and a slot is provided on the shell at a position corresponding to the buckle, and the buckle and the slot cooperate with each other to form a detachable snap-on structure.

[0014] As a further improvement of the present invention, the anti-interference accessory has an opening for installing a resistor, and the opening is sealed by glue potting; the resistor is electrically connected to the plug-in connector.

[0015] As a further improvement of the present invention, after the resistor in the anti-interference accessory is welded to the connector, the connector penetrates the anti-interference accessory and then extends out, and is sealed with the resistor in the opening of the anti-interference accessory by glue potting.

[0016] Beneficial effects of the present invention:

[0017] 1. This solution can use the indicator light itself without installing anti-interference accessories, which can reduce the user's usage cost.

[0018] 2. The anti-interference accessories of this solution are detachably installed on the housing and can be installed in a post-installation manner. There is no need to dismantle and replace the indicator light that has been installed. The replacement efficiency is high and the time cost is low.

[0019] 3. It has the function of flexible switching and can switch between anti-interference state and non-anti-interference state.

[0029] The present invention will be further described below in detail with reference to the embodiments shown in the accompanying drawings.

[0030] Reference Figure 1-7 As shown,

[0031] Reference Figure 1 , 2 As shown in Figures 3, 4 and 5, an indicator light comprises a shell 1, a light-emitting component 2 arranged in the shell 1, a wiring component 3 arranged in the shell 1, the light-emitting component 2 is electrically connected to the wiring component 3, and also comprises an anti-interference accessory 4 detachably mounted on the shell 1, the anti-interference accessory 4 has a conductive plug-in component 41, the wiring component 3 is electrically connected to a contact component 5, when the anti-interference accessory 4 is mounted on the shell 1, the plug-in component 41 cooperates with the contact component 5 to form a conductive contact, so as to electrically connect the anti-interference accessory 4 to the contact component 5 through the plug-in component 41.

[0032] In this solution, the anti-interference accessory 4 is detachably connected to the shell 1, so the anti-interference accessory 4 does not need to be purchased at the beginning of the sale, which can reduce the procurement cost according to demand. When the user purchases and uses it, if he finds that the use environment itself is in an electromagnetic interference environment, he can continue to purchase the anti-interference accessory 4, and achieve anti-interference through the installation between the accessory and the shell 1, avoiding the problem of misleading illumination of the indicator light due to electromagnetic interference in the working environment.

[0033] When installing the anti-interference accessory 4 and the shell 1, first align the connector 41 with the contact 5 on the wiring assembly 3, and then install the anti-interference accessory 4 on the shell 1. At this time, as the anti-interference accessory 4 is installed, the connector 41 will also come into contact with the contact 5 to achieve conductivity, and then connect the anti-interference accessory 4 to the contact 5 to achieve anti-interference effect.

[0034] In the structure of the prior art, the light emitting component 2 and the wiring component 3 are located at both ends of the housing 1. The wiring component 3 itself has a conductive function and is used to connect an external power supply circuit or control circuit. The anti-interference accessory 4 in this solution cooperates with the wiring component 3 and can cooperate with the plug-in connector 41 on the anti-interference accessory 4 and the contact 5 on the wiring component 3. When the anti-interference accessory 4 is installed on the housing 1, the contact 5 can be in contact with the plug-in connector 41 to achieve electrical connection, thereby allowing the anti-interference accessory 4 to be connected to the wiring component 3. The obvious difference is that the wiring component 3 in this solution is provided with a contact 5, which can cooperate with the anti-interference accessory 4 to achieve electrical connection.

[0035] The detachable installation between the anti-interference accessory 4 and the housing 1 can be performed by using screws to install the anti-interference accessory 4 on the housing 1.

[0036] Generally, the bottom of the shell 1 of the indicator light in the prior art has two through holes for operating the wiring assembly 3 inside the shell 1, and the wiring assembly 3 generally has a wiring terminal 31 composed of screws and clips. The through holes at the bottom of the shell 1 are used to operate the internal screws, and the wires extend from the side of the shell 1 at the position corresponding to the wiring terminal 31 and are clamped and installed through the wiring terminal 31. After the operation is completed, the anti-interference accessory 4 can also be installed through the through holes with the screws.

[0037] The contact member 5 may be a socket, and the plug-in member 41 may be a matching plug-in pin, and the two form a contact fit when plugged in to conduct electricity.

[0038] Reference Figure 4 , 5As shown, specifically, the wiring assembly 3 includes two wiring terminals 31 for connecting the live wire and the neutral wire or the positive pole and the negative pole respectively, and the light-emitting assembly 2 is electrically connected to the two wiring terminals 31 to obtain power; both wiring terminals 31 have contacts 5, and the positions corresponding to the two contacts 5 on the anti-interference accessory 4 have plug-ins 41. When the light-emitting assembly 2 is installed on the housing 1, the plug-in connector 41 contacts the corresponding contact 5 for electrical conduction, so as to connect the anti-interference accessory 4 in parallel to the two wiring terminals 31.

[0039] The above-mentioned anti-interference accessory 4 is connected in parallel to the two wiring terminals 31, which is equivalent to being connected in parallel to the two power supply ends of the light-emitting component 2. When an induced current is generated due to the working environment, the anti-interference accessory 4 can be used to control the induced current so that it will not cause the light-emitting group to light up.

[0040] Reference Figure 2 , 4 As shown in FIG. 5 , as another implementation method different from the above-mentioned implementation method using a socket and a pin structure, the contact member 5 in this solution is a clip structure and is used for the insertion and clamping of the connector 41.

[0041] The contact member 5 of the clip structure can be welded to the terminal 31 by welding, or can be fixed to the terminal 31 by bolts. The clip structure has a certain elasticity, which is convenient for clamping and contacting the plug-in member 41 and is also convenient for installation. Of course, in a broad sense, the clip structure can also be interpreted as a socket.

[0042] The above two schemes are adopted to facilitate the installation of the anti-interference accessory 4. When the anti-interference accessory 4 is installed, the connector 41 can be inserted into the contact member 5 through the plug-in effect, and then the anti-interference accessory 4 can be installed on the housing 1 through a detachable installation method. Of course, if the plug-in connection strength is sufficient, it is not necessary to use screws for installation, and the plug-in connection strength can be directly used for assembly, which further facilitates installation and disassembly.

[0043] Reference Figure 4 , 5 As shown, in a specific clamp structure implementation, the contact piece 5 is formed by bending a conductive metal piece to form a clamp structure, and one end of the clip structure corresponding to the anti-interference accessory 4 is tilted to form an opening for inserting the connector 41, and the opening is formed by tilting the clip structure to form a guide slope 51 to guide the connector 41 to be inserted into the clip structure and clamped.

[0044] The processing method of bending the conductive metal part to form the clip structure is convenient and has high processing efficiency. After the metal part is bent, different angles can be formed by changing the degree of bending. The tilting of one end of the clip structure corresponding to the anti-interference accessory 4 is achieved by changing the bending angle to control the angle, so that the end is tilted to form an opening, and the tilting of the opening forms a guide slope 51 to guide the insertion of the plug-in 41, making it more convenient to cooperate with the clip structure, thereby increasing the convenience of installation.

[0045] Reference Figure 3 , 5 As shown in FIGS. 6 and 7 , in order to further facilitate installation, the anti-interference accessory 4 is detachably connected to the housing 1 through a snap-on structure.

[0046] The anti-interference accessory 4 can be installed through a snap-fit ​​structure to further improve the assembly efficiency. The specific snap-fit ​​structure is as follows: Preferably, a snap 6 is provided on the anti-interference accessory 4, and a slot 7 is provided on the housing 1 at a position corresponding to the snap 6. The snap 6 and the slot 7 cooperate with each other to form a detachable snap-fit ​​structure.

[0047] The card slot 7 is arranged on the housing 1, which can maintain the shape of the housing 1 without adding unnecessary structures. By setting the buckle 6 and the card slot 7, the anti-interference accessory 4 can be installed on the housing 1 and the plug-in 41 can be inserted into the contact 5 to complete the card connection.

[0048] The specific clamping structure can be implemented in the following two ways:

[0049] 1. The housing 1 is provided with an insertion hole for the buckle 6 to be inserted. After the buckle 6 is inserted, the barb on the buckle 6 is used to engage with the internal slot 7 of the housing 1, making it difficult to disengage.

[0050] 2. The shell 1 is cylindrical, and an arc-shaped groove is provided along the edge of the end of the shell 1, wherein the diameter of the arc-shaped groove corresponding to the bottom end of the shell 1 is smaller, and the diameter of the side close to the light-emitting component 2 is larger, and the groove as a whole is sunken from the side of the shell 1 to its axis, wherein the edge of the anti-interference accessory 4 is provided with a convex edge, and an annular clamping ring is provided at the position of the convex edge corresponding to the groove. When the anti-interference accessory 4 is installed on the shell 1, the clamping ring on the convex edge is clamped into the groove, and the clamping assembly is completed. In addition, the groove can be filled with paint, and the color of the paint corresponds to the color of the light-emitting component 2, so that the user can see the color of the indicator light when installing the indicator light (when installing the indicator light, it is generally operated on the back of a panel, that is, the user cannot see the color of the light-emitting component 2, but can only see the bottom of the indicator light, and the bottom is generally not marked with color. If it is installed incorrectly, it needs to be removed and corrected, which is easy to cause serious waste of time and cost.)

[0051] In order to increase the sealing performance, the anti-interference accessory 4 has an opening for loading the resistor 42, which is sealed by glue potting; the resistor 42 is electrically connected to the plug-in connector 41. The setting of the opening also facilitates the installation of the resistor 42. The main function of the anti-interference accessory 4 is the resistor 42, which is used to suppress the light-emitting component 2 from emitting light, thereby providing an anti-interference effect. After the glue potting is sealed, the resistor 42 will not shake and has better stability. After the plug-in connector 41 contacts and conducts electricity with the contact 5, the resistor 42 can be provided to the contact 5.

[0052] Reference Figure 7 As shown, further, after the resistor 42 in the anti-interference accessory 4 is welded to the plug-in connector 41, the plug-in connector 41 penetrates the anti-interference accessory 4 and then extends out, and is sealed with the resistor 42 in the opening of the anti-interference accessory 4 by glue potting.

[0053] The connector 41 and the resistor 42 are welded to achieve electrical conduction and high connection strength. The anti-interference accessory 4 may have a through hole for the connector 41 to penetrate. When installing the resistor 42 into the opening, the connector 41 is first allowed to penetrate the through hole, so that it extends out and the resistor 42 is installed into the opening. At this time, as the resistor 42 is installed, the connector 41 will gradually extend until the resistor 42 is installed in place, and then it is filled by glue filling to seal the through hole and the opening. This sealing effect can fix both the resistor 42 and the connector 41, and can also maintain the insulation effect.

[0054] The above solution is composed of the anti-interference accessory 4 and the indicator light, wherein the two can be separated and used separately, or can be used in combination.

[0055] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
