Description

Electrical connection device for a filter

Technical Field

The utility model relates to the field of filter testing, in particular to an electric connection device for a filter.

Background

Filter testing is an essential element in filter applications. In the application of the filter, the inductance value, capacitance value and voltage resistance of the filter can be tested to judge whether the filter meets the production requirement or not, or whether the filter has faults and the reasons of the faults.

In conventional filter testing, one end of an electrical connection wire is usually clamped at an electrical connection portion of a filter or wound around the filter to ensure electrical connection between the electrical connection wire and the filter, and the other end of the electrical connection wire is electrically connected to a testing machine for testing the filter to realize electrical connection between the filter and the testing machine.

Specifically, in some connection schemes of the filter and the testing machine, a screw is arranged on a main body part of the filter, when the filter is tested, the screw is unscrewed, one end of an electric connection wire is wound on the screw, then the screw is screwed, and meanwhile, the electric connection wire is clamped between the main body part and the screw; or, the filter is further provided with a nut adapted to the screw, and when the filter is tested, the nut is screwed, one end of the electrical connection wire is wound on the screw, and then the nut is reversely screwed, so that the electrical connection wire is clamped between the screw and the nut. In other filter test schemes, the filter is provided with an electric connection hole, and one end of an electric connection wire passes through the electric connection hole and is fastened at the electric connection hole to realize electric connection between the electric connection wire and the filter when the filter is tested.

However, the above-mentioned connection scheme of the filter and the testing machine has many problems, for example, when the filter is tested, the connection process of the electrical connection wire and the filter is complicated, additional time cost is required to be increased, and the disassembly is inconvenient, and further, the replacement of the next filter to be tested is inconvenient. And the connection mode between the filter and the electric connection wire is unstable, and the stability of the electric connection between the filter and the testing machine can be affected. In addition, when the filter is tested, a plurality of electric connection wires are required to be connected to different positions of the filter, and the connection is easy to miswire in the connection process, so that the test result is affected. Especially when testing under high voltage (more than 2 KV), misjudgment on test results and even safety problems are easy to occur due to miswiring.

Thus, a new filter electrical connection scheme is desired.

Therefore, the error connection between the filter W and the plurality of electric connection wires can be reduced, and the accuracy and the test safety of the test result are improved.

In the embodiment of the present utility model, the size of the holding cavity 201 is adjustable, that is, the holding cavity 201 is a cavity with adjustable size, so as to facilitate taking and placing of the filter W, and also facilitate accommodating of filters W with different sizes, so that the electrical connection device 100 for filters has higher adaptability, and is applicable to electrical connection of different filters W.

Accordingly, the clamping seat 20 includes at least one movable portion 210 movably mounted to the mounting base 10, and the size of the clamping cavity 201 can be adjusted by adjusting the position of the movable portion 210.

As shown in fig. 1, the movable switch 40 is implemented as a push-pull type quick clamp, and includes a switch base 41, a push rod 42 movably mounted to the switch base 41, an operating member 43 pivotally mounted to the switch base 41, and a transmission member 44 drivingly mounted between the push rod 42 and the operating member 43, wherein one end of the push rod 42 of the movable switch 40 is connected to the transmission member 44, and the other end is connected to the movable portion 210 of the clamping seat 20. The switch base 41 has a through hole 401, and the push rod 42 passes through the through hole 401 to ensure directionality and stability of the push rod 42 during movement. The operator can operate the operating member 43 to drive the push rod 42 to move, so as to drive the movable portion 210 of the clamping seat 20 to move.

Specifically, when the operating member 43 rotates in the first pivoting direction, the push rod 42 drivingly connected to the operating member 43 through the driving member 44 is driven to move in a direction approaching the second clamping wall 22, the movable portion 210 is driven to move in a direction approaching the second clamping wall 22, the size of the clamping cavity 201 is reduced, and the insertion head 310 of the electrical connector 30 moves toward the filter W located in the clamping cavity 201, so that the electrical connection device 100 for a filter is electrically connected to the filter W. When the operating member 43 rotates in the second pivoting direction, the push rod 42 drivingly connected to the operating member 43 via the driving member 44 is driven to move away from the second clamping wall 22, the movable portion 210 is driven to move away from the second clamping wall 22, the size of the clamping cavity 201 increases, and the insertion head 310 of the electrical connector 30 moves away from the filter W of the clamping cavity 201, so that the electrical connection between the electrical connector 100 for a filter and the filter W is disconnected, and the filter W is released by the clamping cavity 201 and can be removed. The operator can place the next filter W to be tested.

It should be noted that, in order to control the movement range of the movable portion 210, the electrical connection device 100 for a filter further includes a contact member 50 extending from the holder 20 into the holding cavity 201, and adapted to contact the filter W. The abutting piece 50 is disposed on the movable piece, and when the movable piece approaches the second clamping wall 22 and the abutting piece 50 abuts against the filter W, the movable piece can be stopped from continuing to move toward the second clamping wall 22, so as to avoid damaging the filter W.

In order to secure the movement stability of the movable portion 210, a guide mechanism may be provided between the mounting base 10 and the movable portion 210. In this particular example, the guide mechanism is implemented as a chute 102-slider structure. Specifically, the mounting base 10 has at least one sliding slot 102 (as shown in fig. 1 to 3), and the movable portion 210 includes at least one sliding block (not shown) that is adaptively received in the sliding slot 102, in such a way that the movable portion 210 is slidably mounted on the mounting base 10 and can move relatively stably along the sliding slot 102.

Specifically, the electrical connection device 100 for a filter further includes a guide rod disposed on the mounting base 10, the movable portion 210 has a guide hole adapted to the guide rod, and the guide rod passes through the guide hole, in this way, the movable portion 210 is movably mounted on the mounting base 10 and can move relatively stably along the guide rod.

It should be understood that the manner in which the movable portion 210 is movably implemented is not a limitation of the present utility model. For example, the movable portion 210 may be directly manually moved to realize the movement of the movable portion 210; for another example, the movement of the movable portion 210 may be achieved by driving the movable portion 210 by a motor.

It should be understood that the implementation of the adjustable size of the clamping chamber 201 is not a limitation of the present utility model. For example, a part of the first clamping wall 21 is movable relative to the second clamping wall 22 and the mounting base 10, i.e. a part of the first clamping wall 21 forms the movable portion 210; for another example, the first clamping wall 21 and the second clamping wall 22 form a first movable portion and a second movable portion, respectively.
