The drawings in the present specification are schematic views to assist in explaining the concept of the present invention, and schematically show the shapes of the respective portions and the mutual relationships thereof.
Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to fig. 1 to 12.
Fig. 1 and 2 show a perspective view of the auxiliary contact module and a perspective view of the removal housing, respectively. The auxiliary contact module 1 comprises a drive rod 11 which is slidably mounted in a housing 12 of the auxiliary contact module and which, in fig. 1, is slidable in the up-down direction of fig. 1. The drive rod has an insert 111 which projects through a slot 13 in the housing, the insert 111 being able to move within the slot as the drive rod slides within the housing 12. In the case of mounting the auxiliary contact module to the contactor, the insert 111 is inserted into a corresponding opening 21 of the mating face of the contactor 2, as shown in fig. 3, and is connected to the drive means of the contactor, so that the drive means of the contactor can drive the drive rod of the auxiliary contact module, thereby changing the contact state of the auxiliary contact module. The relationship of the contactor and auxiliary contact modules is well known to those skilled in the art and will not be described in detail herein.
The auxiliary contact module further comprises a mounting mechanism 14, which is arranged in the housing 12 and which can be switched between a foolproof state, an initial state and an operating state. When the drive rod of the auxiliary contact module and its insert are not in the predetermined position, the mounting mechanism 14 is in a fool-proof state, which can prevent the auxiliary contact module from being mounted to the mating surface of the contactor. When moving the drive lever of the auxiliary contact module and its insert to a predetermined position, the mounting mechanism 14 is switched from a foolproof state to an initial state in which the mounting mechanism is able to lock the drive lever and its insert in the predetermined position and allow the auxiliary contact module to be mounted to the mating face of the contactor. After the auxiliary contact module is mounted to the mating face of the contactor, the mounting mechanism is switched from the initial state to the operating state, releasing the locking of the drive rod and its insert.
As shown in fig. 4, 5 and 6, the mounting mechanism 14 includes a first slider 141 slidably mounted in the housing via an elastic member 142. The elastic member 142 has one end fixed to the housing and the other end fixed to the first slider 141. The first slider is slidable between an initial position and a lock position. In this example, the first slider 141 has a pillar 1411, and the elastic member 142 is fixed to the first slider by fitting over the pillar 1411. The mounting mechanism 14 further includes a second slide 143 slidably mounted within the bore 15 of the housing and disposed on the first slide to be slidable between a protruding position and a retracted position. The sliding direction of the first slider and the sliding direction of the second slider are perpendicular to each other, for example, the sliding direction of the first slider is parallel to the compression direction of the elastic member, and the sliding direction of the second slider is perpendicular to the housing.
As shown in fig. 6, the first slider 141 has a first plane 1412, a first inclined plane 1413 and a third inclined plane 1414, and the second slider 143 has a second plane 1431 and a second inclined plane 1432. In the foolproof state of the mounting mechanism, the first slider 141 is in the initial position, wherein the second flat surface 1431 of the second slider 143 is positioned on the first flat surface 1412 of the first slider, such that the second slider remains in the protruding position, i.e., protrudes through the hole 15, and cannot slide from the protruding position to the retracted position.
In the foolproof state of the mounting mechanism, as shown in fig. 7 and 8, the elastic member 142 urges the first slider 141 in the initial position along the arrow shown in fig. 8. At this time, the second slider 143 is positioned on the first plane 1412 of the first slider 141, as shown in fig. 8, so that the second slider 143 cannot move. The second slider has a stop 1433 configured to abut a portion of the housing surrounding the aperture in the protruding position of the second slider to prevent the second slider from sliding out of the housing.
During the switching of the mounting mechanism from the foolproof state to the initial state, that is, during the movement of the drive lever 11 to the predetermined position, the drive lever 11 abuts against the third inclined surface 1414 of the first slider 141, thereby pushing the first slider 141 from the initial position toward the lock position, and after the movement of the drive lever to the predetermined position, the first slider 141 is moved to the lock position, at which time a portion of the drive lever 11 is accommodated in the groove 1415 of the first slider, and is locked by the first slider at the predetermined position, as shown in fig. 9 and 10.
Further, as the first slider 141 slides from the initial position to the locking position, the first inclined surface 1413 of the first slider 141 moves below the second inclined surface 1432 of the second slider 143, aligning with the second inclined surface 1432, so that the second slider can slide from the protruding position to the retracted position under the urging of an external force.
As shown in fig. 11 and 12, during the switching of the mounting mechanism from the initial state to the operating state, i.e., during the insertion of the insert into the corresponding opening of the contactor's mating device to mount the auxiliary contact module to the mating surface of the contactor, the second slider 143 is pushed by the mating surface of the contactor, sliding from the protruding position toward the retracted position, which causes the second slider 143 to push the first slider 141 via the first and second slopes 1413 and 1432 (as shown by arrow a1 in fig. 12), causing the first slider 141 to further slide from the locked position to the unlocked position (as shown by arrow a2 in fig. 12) at which the first slider is spaced from the drive lever by a certain distance, releasing the locking of the drive lever.
Through the utility model discloses a contactor can be installed reliably to auxiliary contact module's installation mechanism to three kinds of states, and installation mechanism is in preventing slow-witted state before the installation, prevents that auxiliary contact module from installing the contactor, is in locking state when the installation, makes auxiliary contact module conveniently install the contactor, does not need any other instrument, is in operating condition after the installation, makes the actuating lever can freely remove.
Moreover, the technical features disclosed above are not limited to the combinations with other features disclosed, and other combinations between the technical features can be performed by those skilled in the art according to the purpose of the invention to achieve the aim of the invention.
