[0014] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0015] Figures 1-2 This utility model presents a schematic diagram of the fixing device for sealing thermistors. Detailed Implementation

[0016] The present invention will be further described below with reference to embodiments:

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0018] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0019] like Figure 1 As shown, the present invention relates to a fixing device for sealing thermistors, which includes a sealing cable board. The sealing cable board is inverted U-shaped to increase the distance between the slots and prevent siphoning caused by excessive closeness. Multiple mounting slots are provided in the middle of the sealing cable board.

[0020] The mounting slots are used to install thermistors, and each mounting slot can accommodate one thermistor. Therefore, multiple thermistors can be simultaneously mounted and sealed on the sealing cable board.

[0021] Specifically, there are 20 mounting slots, spaced apart. The middle section of each mounting slot consists of a pair of oppositely arranged arc-shaped channels. The upper end of each arc-shaped channel is connected to a straight channel, and the two straight channels are parallel to each other. The lower end of each arc-shaped channel is connected to a channel that curves inward at the bottom. The two channels are symmetrically arranged, and the extended lines of the bottom ends of the channels can be compared at a single point.

[0022] It also includes adhesive tape and multiple thermistors, each of which can be mounted in a corresponding mounting slot. Specifically, it snaps into and secures the thermistors to the mounting slot. The adhesive tape is used to further secure the thermistors to the mounting slot.

[0023] In this invention, the sealing cable board has a special curved channel structure that matches the shape of the thermistor, which can effectively separate the thermistor wires and avoid capillary action caused by the close proximity.

[0024] The working process of the fixing device for sealing the thermistor of this utility model:

[0025] 1. The thermistor is first assembled with the encapsulated ribbon cable board;

[0026] 2. Then, use tape to further secure the thermistor to the sealing cable board;

[0027] 3. During the sealing process, due to the special bending structure of the sealing cable board, the wires can be guided after the thermistor is assembled (the wires are soldered to the pins at both ends of the thermistor chip in the previous process, and the two ends of the wires are separated by the mounting board slot structure). If the contact distance is too close, capillary action will cause a siphon effect, causing the adhesive to climb up along the wires, resulting in adhesive overflow or falling off after solidification.

[0028] A fixing device for sealing thermistors consists of a sealing cable board, tape, and multiple thermistors.

[0029] The sealing cable board is in the shape of an inverted convex character, and 20 mounting slots are provided in the middle of the sealing cable board.

[0030] The mounting slots are used to install thermistors, and each slot can hold one thermistor. Therefore, up to 20 thermistors can be mounted and sealed simultaneously on the ribbon cable.

[0031] The middle section of each mounting slot consists of a pair of oppositely arranged arc-shaped channels. The upper end of each arc-shaped channel is connected to a straight channel, and the two straight channels are parallel to each other. The lower end of each arc-shaped channel is connected to a channel that curves inward at the bottom. The two channels are symmetrically arranged, and the extended lines of the bottom ends of the channels can be compared at a single point.

[0032] The 20 thermistors can be installed in their respective mounting slots and secured with the slots by snap-fit. The tape is used to further secure the thermistors to the mounting slots.

[0033] like Figure 2 As shown, the sealing cable board is 300mm long and 40mm wide; the mounting groove area is 240mm long and 40mm wide.

[0034] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
