Description

Technical Field

[0001] This utility model belongs to the field of filament lamp technology, and more specifically, relates to a filament holder that can be tested at one end and a filament using the holder. Background Technology

[0002] In the traditional filament lamp manufacturing process, the electrical performance test of the filament bracket usually requires contacting and energizing both the positive and negative terminals at both ends of the filament simultaneously. Because the positive and negative terminals are located at both ends of the substrate, the test can be carried out normally without short circuit. However, due to some special structural requirements, the pins of the positive and negative terminals of the filament must be located at the same end of the substrate.

[0003] In existing technologies, the positive and negative pins are generally integrally formed and connected to conduction. As a result, the positive and negative pins cannot be tested normally. During the production process, if defects such as poor soldering or missing soldering occur, they cannot be detected immediately through power-on testing, which increases the production defect rate. Therefore, it is necessary to design a substrate that can perform power-on testing when the positive and negative pins are on the same end. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a filament bracket that can be tested at one end and a filament using the bracket, which can make the positive and negative poles at the same end and can be tested by power-on.

[0005] This utility model discloses a filament holder capable of single-end testing, comprising several filament strips, connectors, and auxiliary components; the filament strips are arranged at intervals; each filament strip includes a substrate, a first pin, and a second pin; the first pin and the second pin are respectively fixedly connected to the substrate and are located on the same side of the substrate; the end of the first pin away from the substrate is fixedly connected to the auxiliary component via the connector; the end of the second pin away from the substrate is fixedly connected to the auxiliary component.

[0006] The first and second pins are made of conductive material;

[0007] The connector is an insulated component.

[0008] As a further improvement of this utility model, the connector is an integrally formed component; or,

[0009] The connector consists of several connecting pieces.

[0010] As a further improvement of this utility model, one first pin corresponds to one connecting piece.

[0011] As a further improvement of this utility model, the auxiliary component is integrally formed with the second pin;

[0012] The auxiliary component is made of conductive material; the second pin is fixedly connected and conductive through the auxiliary component.

[0013] As a further improvement of this utility model, the auxiliary component is provided with a plurality of auxiliary pins; the auxiliary pins are matched with the first pins; the end of the auxiliary pin away from the auxiliary component is fixedly connected to the end of the connector away from the first pin.

[0014] As a further improvement of this utility model, the auxiliary pin is positioned opposite to and spaced apart from the first pin.

[0015] As a further improvement of this utility model, conductive lines are arranged on the front and / or back sides of the substrate along the extension direction of the substrate for arranging light-emitting chips.

[0016] The input terminal of the conductive circuit is provided with two paths, one of which is electrically connected to the first pin and the other is electrically connected to the second pin.

[0017] As a further improvement of this utility model, the connector is made of plastic.

[0018] As a further improvement of this utility model, the end of the first pin away from the substrate and the auxiliary pin are both embedded in the top of the connector.

[0020] The first pin is the negative terminal of the filament, and the second pin is the positive terminal of the filament.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] Single-ended test function: The first and second pins are located on the same side of the substrate and are fixed by an auxiliary component and a connector. The connector is an insulating component. With this configuration, when the first and second pins correspond to the positive and negative terminals respectively, the first and second pins are in an open state, and the operator can perform a power-on test.

[0023] The auxiliary component is made of conductive material and is integrally formed with the second pin, so that the second pin can be fixed and conductive through the auxiliary component, reducing the need for independent wire connections. With this setting, the test fixture only needs to be set up with a common level for testing the second pin, simplifying the design of the test fixture. Attached Figure Description
