Description

Technical Field

[0001] This utility model relates to the field of electronic component fixing technology, and in particular discloses an NTC fixing structure for the conductive connection part of an electrode holder. Background Technology

[0002] During the operation of electronic devices, NTCs, as temperature-sensitive components, are often installed on the conductive connections of electrode holders to monitor and control temperature. When the conductive connections of the electrode holders are encapsulated with plastic, the space between the back cover and the internal structure is extremely small in order to minimize the overall volume of the conductive connections. This makes it difficult to add more components internally. Currently, common methods for fixing the conductive connections between NTCs and electrode holders include wrapping, welding, crimping, plugging, and bonding. However, these methods have many problems. For example, simple wrapping or binding not only provides poor fixation and is prone to loosening during device operation, affecting the normal operation of the NTC, but also results in messy wiring, occupies a lot of space, and is not conducive to the organization and maintenance of internal wiring. While welding provides a relatively strong connection, the welding process is complex, requires high operational skills, and is difficult to adjust if the welding position deviates. Welding can also damage the NTC component. The adhesives used for bonding are greatly affected by the environment; high temperature and high humidity can reduce the bonding strength, and it is inconvenient to repair and replace components. Therefore, there is an urgent need for a fixed structure that meets the requirements for stability, convenience and reliability in actual use. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide an NTC fixing structure for the conductive connection part of the electrode holder.

[0004] To achieve the above objectives, the present invention provides an NTC fixing structure for the conductive connection portion of an electrode holder, characterized in that: it includes a clamping member having a slot and a receiving cavity; the slot is used to accommodate the conductive connection portion of an external electrode holder, and the clamping member is clamped onto the conductive connection portion of the external electrode holder; the receiving cavity is used to accommodate an external NTC component.

[0005] Furthermore, the clamping member has a body and two clamping arms protruding from the body. The two clamping arms and the body form a slot, and the clamping member is detachably fixed to the conductive connection part of the external electrode seat by the squeezing force generated by the two clamping arms.

[0006] Furthermore, the clamping member is provided with a welding hole communicating with the slot, through which external solder enters the slot to connect the conductive connection part of the external electrode holder to the clamping member.

[0007] Furthermore, the clamping member is provided with an anti-slip structure, which can be strip-shaped, dot-shaped, wavy, or mesh-shaped, and the anti-slip structure protrudes from the side of the clamping member facing the slot.

[0008] Furthermore, the clamping member is provided with a guide structure, the guide structure having an inclined surface, and the clamping member is slidably mounted to the conductive connection part of the external electrode seat via the inclined surface.

[0009] Furthermore, the clamping member also has a stop arm located at the end of the slot. When the clamping member is installed on the conductive connection part of the external electrode seat, the stop arm is located at the end of the conductive connection part of the external electrode seat. The stop arm is used to guide the clamping member to be accurately installed on the conductive connection part of the external electrode seat.

[0010] Furthermore, the clamping member also includes a mounting part, which is a flexible metal sheet. The metal sheet is rolled up to form a receiving cavity, in which the external NTC component is located and fixed to the conductive connection part of the external electrode holder via the clamping member.

[0012] Furthermore, the mounting part and the clamping member are an integral structure. One end of the mounting part protrudes from the surface of the clamping member, and the other end of the mounting part protrudes away from the clamping member and curls to form a receiving cavity.

[0013] Furthermore, the receiving cavity is cylindrical, and the central axis of the receiving cavity is perpendicular or parallel to the conductive connection part of the external electrode holder.

[0036] Specifically, the clamping member 1 is provided with a welding hole 3 communicating with the slot. External solder enters the slot through the welding hole 3 to connect the conductive connection part of the external electrode seat to the clamping member 1.

[0037] In actual use, the welding hole 3 is located in the center of the clamping plate 2, and the welding method is soldering.
