Description

Technical Field

[0001] This utility model relates to the field of display technology, and more specifically, to an NTC and connector welding positioning fixture. Background Technology

[0002] With the rapid development of economy and technology, NTC thermistors have been widely used. With the advent of Industry 4.0 and the era of big data, the application fields of NTC thermistors are becoming increasingly broad.

[0003] NTC pins are generally made of thin copper-clad steel. Because the material is hard and has a certain degree of elasticity, the pins are not easy to fix when soldering with connectors and may move or lift up, resulting in poor soldering.

[0004] Therefore, it is necessary to propose a positioning fixture for welding NTC and connectors. Utility Model Content

[0005] This invention provides a positioning fixture for welding NTC and connectors to solve the problems of easy movement or lifting of existing NTC pins and poor welding quality during welding.

[0006] According to one aspect of the present invention, an NTC and connector welding positioning fixture is provided, comprising a pressure plate and a base plate. The base plate is provided with an mounting groove for mounting the connector and a receiving groove for accommodating the NTC. A protruding ridge is provided between the mounting groove and the receiving groove. A positioning groove is provided on the protruding ridge, and a magnet for adsorbing and fixing the NTC is provided at the bottom of the positioning groove. Guide posts are provided at the four corners of the base plate, and an arc-shaped groove adapted to the guide posts is provided on the pressure plate.

[0007] Based on the above scheme, preferably, the pressure plate is provided with a male locking end, and the base plate is provided with a female locking end that is adapted to the male locking end.

[0008] Preferably, based on the above scheme, the male end of the lock is provided with a locking rod, and a limiting rod is inserted into the bottom of the locking rod. The female end of the lock is provided with a locking groove, which is adapted to the locking rod and the limiting rod. When the locking rod is inserted into the locking groove, the limiting rod is rotated to make it engage with the female end of the lock, thereby achieving locking.

[0009] Preferably, based on the above scheme, the pressure plate is provided with a pin pressing block, and the pin pressing block is arranged opposite to the positioning groove.

[0010] Preferably, based on the above scheme, the end face of the pin clamping block is provided with a flange for clamping the NTC and a locking block for clamping the connector.

[0011] This utility model discloses an NTC and connector welding positioning fixture. A magnet is set on the base plate so that the resistor pins of the NTC are attached to the base plate. The resistor pins are pressed and positioned by a pressure plate with resistor pin clamping blocks, so that the resistor pins are in close contact with the connector pins. This prevents the resistor pins from lifting up or being lifted by the welding head during the welding process, making the welding quality more stable and greatly improving the first pass rate.

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0022] It should be understood that, when used in this specification and the appended claims, the term "comprising" indicates the presence of a descriptive feature, integral, step, operation, element, and / or component, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or sets.

[0023] To keep the drawings concise, only the parts relevant to this invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0024] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0025] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various components of this invention are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the descriptions of the positions of these components change, these directional indications also change accordingly.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0028] Please see Figure 1 and combined Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an NTC and connector welding positioning fixture, including a pressure plate 1 and a base plate 2.

[0029] The base plate 2 has a mounting slot 21 for installing connectors and a receiving slot 22 for accommodating NTCs. A protruding rib 23 is provided between the mounting slot 21 and the receiving slot 22. A positioning slot 24 is provided on the protruding rib 23. A magnet 25 is provided at the bottom of the positioning slot 24 and is positioned corresponding to the positioning slot 24. For details of the structure, please refer to [link to relevant documentation]. Figure 4 .

[0030] Guide posts 26 are provided at the four corners of the base plate 2, and arc grooves 11 adapted to the guide posts 26 are provided on the pressure plate 1. When the pressure plate 1 moves toward the base plate 2, the interaction between the guide posts 26 and the arc grooves 11 ensures the positioning and closing of the pressure plate 1 and the base plate 2.

[0031] Please continue reading. Figure 5 and Figure 6 The pressure plate 1 is provided with a male locking end 12, and the base plate 2 is provided with a female locking end 27 that is adapted to the male locking end 12. The male locking end 12 is provided with a locking rod 121, and a limiting rod 122 is inserted into the bottom of the locking rod 121. The center line of the limiting rod 122 is perpendicular to the center line of the locking rod 121.

[0032] The lock nut end 27 of this utility model is provided with a lock groove 271, which is adapted to the locking rod 121 and the limiting rod 122 to realize the quick locking and releasing of the pressure plate 1 and the base plate 2.

[0033] Furthermore, to ensure the accurate relative positioning of the NTC and the connector, this invention provides a pin clamping block 13 on the pressure plate 1, which is positioned opposite to the positioning groove 24. The end face of the pin clamping block 13 protrudes outwards with a flange 131 for clamping the NTC and a locking block 132 for clamping the connector, ensuring that the NTC pins and connector pins maintain close contact during soldering, preventing the NTC pins from lifting during soldering, and greatly improving soldering stability and yield.

[0034] In use, place the connector in the mounting slot 21 and the NTC in the receiving slot 22. Its pins pass through the positioning slot 24 and are attracted and fixed by the magnet 25. Close the pressure plate 1 and lock it with the male locking end 12 and the female locking end 27. The flange 131 and the locking block 132 of the pin pressing block 13 press the NTC pins and the connector respectively. After positioning is completed, soldering is performed.

[0035] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
