Problems solved by technology
[0004] However, the above-mentioned composite protector structure has the following disadvantages: since the finished fuse is built inside the insulating tube, and there is a large porcelain tube in the finished fuse that is sleeved outside the temperature-sensitive body, it takes up a relatively large space inside the insulating tube. , so that the overall size of the product is relatively large, it is difficult to reduce, it cannot effectively save space, and greatly reduces the space utilization rate

Embodiment Construction
[0042] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0043] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open-ended term, so it should be interpreted as "including but not limited to". "Appr...

Abstract
The invention discloses a composite protector and a manufacturing method thereof, and the composite protector comprises: an insulating tube, wherein two ends of which are respectively sleeved with a first conductive cap and a second conductive cap; a resistance wire which is wound on the outer surface of the insulating tube and is electrically connected with the first conductive cap and the second conductive cap respectively; a fuse which is accommodated in the insulating tube, wherein the fuse comprises a temperature fuse link and a first lead and a second lead which are connected with two ends of the temperature fuse link, the first lead extends out of the first conductive cap, and the second lead is bent along the direction of the first lead and is electrically connected with the first conductive cap; and insulating parts which are arranged between the temperature fuse link and the second lead at intervals, so that the second lead is insulated from the temperature fuse link and the first lead respectively. According to the invention, a porcelain tube sleeved outside the temperature fuse is omitted, so that the internal space, occupied by the fuse, of the insulating tube can be reduced, and the size of the whole product is reduced; moreover, the fuse without the porcelain tube is cheaper than the existing finished fuse, so that the production cost can be reduced.
Description
technical field [0001] The invention belongs to the technical field of electrical protection devices, and in particular relates to a composite protector and a manufacturing method thereof. Background technique [0002] Composite protectors are generally formed by connecting resistors and thermal fuses in series. Composite protectors are mostly used in chargers or adapters to effectively protect against over-temperature and over-current. The adapter is deformed or even damaged. [0003] The specific structure of the current composite protector is as follows: figure 1 As shown, it includes an insulating tube 1' with an open end and a fuse 2' arranged in the insulating tube 1'. Caps 3' are provided at both ends of the insulating tube. The fuse 2' includes a temperature sensing body and two fuses connected to the temperature sensing body There are two lead wires 21', and a ceramic tube is provided on the temperature sensing body outer jacket, one of which leads out of the insu...
