Description

  The present invention relates to electronic devices, and more particularly to positive temperature coefficient (PTC) thermistor devices.

  The thermistor device is widely used in a current limiting circuit including a motor starting circuit of a cooling device such as a refrigerator. When used for a long period of time, the physical structure of the prior art PTC device can deteriorate, causing abnormal heat generation inside the device and breaking the PTC element into pieces. Since these pieces may still be in contact with the terminals, problems such as arcing, overheating, and overcurrent may occur.

  Patent Document 1 introduces an electronic device that includes two spring contact portions and two non-conductive contact portions. In operation, the four contact portions are in contact with the PTC and the two spring contact portions are welded to the left and right terminals, respectively. On the other hand, the material close to the PTC (non-conductive contact portion) needs to be resistant to high temperatures and is therefore relatively expensive. On the other hand, if the PTC is damaged without interrupting the current, the PTC fragment can still be electrically connected to the terminals, causing arcing and overheating.

  Patent Document 2 introduces a thermistor device including three elastic supports and a pair of insulated offset posts, the two elastic supports are welded to the terminals, and the third elastic support is welded to the other terminals. The The pair of offset posts are spaced from the thermistor element. Since the post does not contact the PTC element, an expensive material resistant to high temperatures is not required. However, if the thermistor breaks without interrupting the current, the thermistor fragments may still be electrically connected to the terminals, causing arcing and overheating.

  FIG. 1 is a perspective view of an electronic device 100, such as a PTC thermistor device, according to one embodiment of the invention in an assembled state. FIG. 2 is a perspective view of the PTC thermistor device in an exploded state.

  As shown in FIG. 2, the electronic device 100 includes a cover 1, a base 2, a first terminal 3, a second terminal 4, and an electronic element 5. The electronic element 5 is, for example, a PTC disk. The electronic element has a first electrode 51 and a second electrode 52 that are arranged on opposite sides.

  The electronic device 100 further includes a first support 7 having a first contact portion 71 that is in contact with and electrically connected to the first electrode 51, and a second support that is in contact with and electrically connected to the second electrode 52. And a second support 8 having two contact portions 81. The first support 7 is mounted on and electrically connected to the first terminal 3. The second support 8 is mounted on and electrically connected to the second terminal 4. Preferably, the first support 7 is formed integrally with the first terminal 3. Preferably, the second support 8 is formed integrally with the second terminal 4. The second support 8 is a solid support. Preferably, the first support 7 is a solid support. Alternatively, the first support 7 may be an elastic support.

  The electronic device 100 further includes a third elastic support 6. The third support 6 is, for example, a spring. The third support 6 has a third contact portion 63 that contacts the second electrode 52 at a position close to the second contact portion 81. Preferably, the third contact portion 63 is separated from the second contact portion 81. Alternatively, the third contact portion 63 may contact or overlap the second contact portion 81.

  The third support 6 preferably includes a first elastic part 61 and a second elastic part 62. The first elastic portion 61 provides a third contact portion 63. The second elastic portion 62 includes a fourth contact portion 64. The fourth contact portion 64 is in contact with the second electrode 52 at a different position from the second contact portion 81 and the third contact portion 63.

  FIG. 3 is a top view of the PTC thermistor with the cover removed. As shown in FIG. 3, the first contact portion 71 is closer to the center of the electronic element 5 than the second contact portion 81 and the fourth contact portion 64. The four contact portions 64 face each other across the first contact portion 71. Preferably, the first contact portion 71 is positioned at the center of the electronic element 5, and the line connecting the first contact portion 81 and the fourth contact portion 64 passes through the center of the electronic device. In other words, the second contact portion 81 and the fourth contact portion 64 are positioned on the two radial sides of the first contact portion 71. The first contact portion 71 is in contact with the first electrode 51 of the electronic element 5 at a substantially central position. The second contact portion 81 is in contact with the second electrode 52 of the electronic element 5. The first elastic part 61 applies an elastic force to the electronic element 5 via the third contact part 63. The second elastic part 62 applies an elastic force to the electronic element 5 via the fourth contact part 64. Therefore, the first support 7 and the second support 8 apply a force toward the electronic element 5 against the elastic force of the first elastic part 61 and the second elastic part 62, and as a result, A closer contact can be formed between the first contact portion 71 and the first electrode 51 and between the second contact portion 81 and the second electrode 52. In this way, the electronic element 5 forms a more reliable connection between the first terminal 3 and the second terminal 4.

  The elastic force applied to the electronic element by the second elastic portion 62 needs to be larger than that applied to the electronic element by the first elastic portion 61, and as a result, the first support 7 and the second One skilled in the art understands that the support 8 can apply a force toward the electronic element 5 to achieve intimate contact.

The force applied by the first support 7 is usually greater than the force applied by the second support 8. In a fault condition, the force applied by the first support 7 close to the center of the electronic element 5 increases the possibility that the surface passing through the center will break.

  FIG. 6 shows that the electronic element 5 breaks along a plane passing through the vicinity of the center in a failure state. The elastic force of the first elastic part 61 having the third contact part 63 drives the piece of the electronic element 5 away from the second contact part 81 and separates the piece from the second contact 81. That is, the second support 8 is not in contact with the second electrode. Since the second support 8 is a rigid support that does not compress, the second support no longer contacts the electronic element 5 when the first elastic part 61 pushes the piece. In the failure state, the third elastic support 6 is insulated from the second support 8 and the second terminal 4. For example, the third elastic support 6 is made of an insulating material. Alternatively, if the third elastic support 6 is electrically conductive, the third support 6 is spaced from the second support 8 and the second terminal 4 or spaced through an insulating material. The Therefore, the electrical connection between the electronic element 5 and the second terminal 4 is cut off, and the fragment is cut off from the circuit, thus preventing a short circuit.

The elastic force applied to the electronic element 5 by the second elastic portion 62 is larger than the sum of the elastic forces applied by the two elastic forks 61a and 61b. In a normal operation state, the first support 7 and the second support 8 apply a force to the electronic element 5 to realize intimate contact. In the failure state, the two elastic forks 61a and 61b push the piece of the electronic element 5 away from the second contact portion 81, and as a result, the second support 8 is not in contact with the second electrode 52, Fragments are disconnected from the circuit.

The first elastic part 61 is not limited to including the two elastic forks 61a and 61b, so that the balance of the electronic device 100 can be maintained, and the fragment can be separated from the second contact part in a failure state. Those skilled in the art will appreciate that other numbers of forks may be included as long as they are pressed.
