Description

Technical Field

[0001] The present invention relates to the technical field of electronic component fixing, and particularly discloses an NTC fixing structure for an electrode base that is convenient for optimizing the circuit space. Background Art

[0002] During the operation of electronic devices, as a temperature-sensitive component, an NTC often needs to be installed on an electrode base to achieve temperature monitoring and control. When the rear cover of the electrode base is plastic-sealed, in order to minimize the volume of the overall electrode base as much as possible, the free space between the rear cover and the internal structure is extremely small, which makes it difficult to continue adding parts inside. Currently, common fixing methods for NTCs and electrode bases include winding and bundling, welding, crimping, plugging, and bonding, etc. However, these fixing methods have many problems. For example, simple winding or bundling not only has a poor fixing effect and is prone to loosening during the operation of the device, affecting the normal operation of the NTC, but also the circuits are messy and occupy a large amount of space, which is not conducive to the arrangement and maintenance of the internal circuits of the device; although welding provides a relatively firm connection, the welding process is complex, has high requirements for operation, and once the welding position deviates, it is difficult to adjust. At the same time, welding may also damage the NTC component; the adhesives used in bonding are greatly affected by the environment, and high temperature and high humidity will cause the bonding strength to decrease, and it is not convenient for repairing and replacing components. Therefore, there is an urgent need for a fixing structure to meet the requirements of stability, convenience, and reliability in actual use. Summary of the Invention

[0003] In order to overcome the disadvantages and deficiencies existing in the prior art, the purpose of the present invention is to provide an NTC fixing structure for an electrode base that is convenient for optimizing the circuit space.

[0004] To achieve the above purpose, an NTC fixing structure for an electrode base that is convenient for optimizing the circuit space according to the present invention is characterized in that: it includes a limiting member of an integrated structure, the limiting member has a first installation part and a second installation part, and the first installation part is connected to the second installation part; the first installation part has a limiting groove for accommodating the conductive connection part of an external electrode base, and the first installation part clamps on the conductive connection part of the external electrode base; the second installation part has a receiving cavity for accommodating the NTC component.

[0005] The present invention realizes the fixation between the NTC and the electrode base by setting the first installation part and the second installation part. Among them, the second installation part is provided with a receiving cavity for accommodating the circuits of the external NTC. The first installation part is installed on the external electrode base, and the second installation part is connected to the first installation part. The circuits of the NTC are received in the receiving cavity, making the circuit arrangement more orderly, effectively optimizing the circuit space inside the device, and facilitating the maintenance and repair of the device.

[0006] Furthermore, the first mounting portion has a body, a first clamping plate and a second clamping plate protruding from the body, and a limiting groove is formed by surrounding the body, the first clamping plate and the second clamping plate.

[0007] Furthermore, one end of the second mounting portion protrudes from the first clamping plate and extends away from the first clamping plate, and the other end of the second mounting portion curls towards the first clamping plate to form a receiving cavity, the receiving cavity has an opening, and an external NTC component enters the receiving cavity through the opening.

[0008] Furthermore, a heat-conducting glue block is accommodated in the receiving cavity, and an external NTC component is fixed in the receiving cavity through the heat-conducting glue block.

[0009] Furthermore, the heat-conductivity coefficient of the limiting member is greater than 50 W / (m·K).

[0010] Furthermore, the extending direction of the receiving cavity is parallel or perpendicular to the extending direction of the conductive connection portion of the external electrode seat, and the external NTC component located in the receiving cavity is parallel or perpendicular to the external electrode seat.

[0011] In the present invention, the vertical or parallel relationship between the circuit and the electrode seat can be adjusted according to actual needs, so that the circuit layout is more neat and orderly, effectively optimizing the circuit space inside the device and facilitating the maintenance and repair of the device.

[0012] Furthermore, the first mounting portion is provided with a welding hole communicating with the limiting groove, and external solder enters the limiting groove through the welding hole for welding the first mounting portion and the conductive connection portion of the electrode seat together.

[0013] Furthermore, the first mounting portion is provided with anti-slip ribs protruding into the limiting groove and contacting the conductive connection portion of the external electrode seat.

[0014] Furthermore, the first mounting portion is provided with a guiding inclined surface for guiding the limiting member to be quickly mounted on the conductive connection portion of the external electrode seat.

[0015] Furthermore, the first mounting portion is further provided with a baffle, the baffle covers the limiting groove, and when the first mounting portion is positioned and mounted on the conductive connection portion of the external electrode seat, the baffle is located above the conductive connection portion of the external electrode seat.

[0016] In the present invention, the detachable fixation of the first mounting portion and the electrode base is achieved through the extrusion force formed by two parallel first clamping plates and second clamping plates. At the same time, the connection is further strengthened by cooperating with the welding holes to ensure that the NTC fixing structure will not loosen during the operation of the device, and to ensure that the NTC can work stably. The setting of the anti-slip ribs also effectively prevents the relative sliding between the first mounting portion and the electrode base or the NTC, further enhancing the fixing effect. The chamfered inclined surface design of the clamping plate enables the first mounting portion to be easily mounted on the external electrode base from all directions, reducing the installation difficulty, improving the installation efficiency, and saving the installation time and labor cost. The baffle can prevent the first mounting portion from sliding when the installation part of the electrode base is small, enhancing the adaptability of the fixing structure. The combination of various functions enables the NTC fixing structure of the present invention to better meet the actual use requirements.

[0017] The beneficial effects of the present invention: The detachable fixation of the first mounting portion and the electrode base is achieved through the extrusion force formed by two parallel first clamping plates and second clamping plates. At the same time, the connection is strengthened by cooperating with the welding holes and anti-slip ribs; the NTC component is fixedly received via the second mounting portion, and the first mounting portion and the second mounting portion provide multiple orientations, optimizing the circuit layout of the NTC.
