43, an edge switch cover 39 is slided.
Here, as shown in fig. 7, from the two pairs of external connection terminals of switch conductive plate 31 protruding to the outside of switch cover 39
32, it is connected with electric conductor 18a, the 18b being made up of copper barred body.As shown in Fig. 2 the electric conductor 18a, 18b are by two pairs of switches
The part that conductive plate 31 is connected in parallel.Also, the other electric conductor being made up of the lead being connected with magnet coil 17d, 17e
19a, 19b are connected with the one end of the electric conductor 18a, 18b.
Below, reference picture 8 is illustrated electric conductor 18a（18b）With the outside of the switch element 30 for being arranged at present embodiment
The operation of the connection of connection terminal 32.
External connection terminals 32 are shape of a pair of connection sheets 32a, 32a in two dichotomies, therefore, such as Fig. 8（a）Institute
Show, make electric conductor 18a（18b）It is relative with external connection terminals 32, from being configured to a pair of connections between a pair of connection sheets 32a, 32a
The inside of piece 32a, 32a.
Then, such as Fig. 8（b）It is shown, thrust F1 is applied to external connection terminals 32, so that a pair of connection sheets 32a, 32a
Close Direction distortion to each other.Thus, even if operating personnel remains electric conductor 18a without hand（18b）, it is also possible to by conduction
Body 18a（18b）It is temporarily fixed on external connection terminals 32.
Then, such as Fig. 8（c）It is shown, it is being temporarily fixed on the electric conductor 18a of external connection terminals 32（18b）Periphery with
Between external connection terminals 32, connecting portion 45 is set by soldering or welding.
Below, the action of the electromagnetic contactor 10 of present embodiment is illustrated.
In the electromagnetic contactor 10 of the off state of Fig. 1, encouraged by the connection magnet coil 17d to electromagnet 17
Magnetic, electromagnetic force is produced in a fixed iron core 17a.Thus, movable core 17i overcomes the elastic force of back-moving spring 27, is adsorbed to
Fixed iron core 17a, movable frame 23 is moved downwards.When moving contact 24 is moved downwards, as shown in figure 9, movable contact 25
It is connected with fixed contact 15b, the electromagnetic contactor 10 being turned on.
As movable core 17i and mono- side shiftings of fixed iron core 17a in the same direction of movable frame 23 1, it is formed in movable frame 23
Thrust piece 28 is moved downwards, also, the switch moving contact supporting member 34 of switch element 30 resists moving contact biasing springs
35 elastic force and move.Due to the movement of the switch moving contact supporting member 34, the two couples switch as switching switch 18 is movable
The off-state that contact 36 leaves from switch fixed contact 33.Thus, the exciting current for flowing through connection magnet coil 17d is passed to
Connect magnet coil 17d and keep magnet coil 17e both sides, electromagnetic force is produced in fixed iron core 17a, 17b both sides, keep movable
The contact condition of contact 25 and fixed contact 15b.
In addition, housing of the invention is corresponding with lower house 11, upper shell 12, extinguishing arc cover 13, movable support portion of the invention
Connecting portion 22 with movable frame 23 is corresponding.
Below, the action effect of present embodiment is illustrated.
When by electric conductor 18a（18b）External connection terminals 32 with the switch element 30 for being arranged on present embodiment are connected
When, make electric conductor 18a（18b）It is in the phase of external connection terminals 32 of the shape of two dichotomies with a pair of connection sheets 32a, 32a
It is right, by electric conductor 18a（18b）From being configured to a pair of inside of connection sheet 32a, 32a between a pair of connection sheets 32a, 32a, therefore,
In lower house 11, it is not necessary to ensure around for by external connection terminals 32 and electric conductor 18a（18b）The broadness of connection is empty
Between.
In addition, applying thrust F1 by external connection terminals 32, make a pair of connection sheets 32a, 32a towards each other close to side
To deformation, by electric conductor 18a（18b）External connection terminals 32 are temporarily fixed at, operating personnel remains electric conductor 18a without hand
（18b）, it becomes possible to enter to exercise electric conductor 18a（18b）The soldering being connected with external connection terminals 32 or weld job, accordingly, it is capable to
Labour and the external connection terminals of time 32 and electric conductor 18a are enough greatly shortened compared with prior art（18b）Company
Connect.
Present embodiment illustrates possess two pairs of switch elements of external connection terminals 32 30, and by a pair of outer connection end
A 32 and electric conductor 18a of son（18b）The structure of connection, but, the present invention is not limited to this, even possessing a pair of outer
The switch element of connection terminal 32, is configured to make an external connection terminals 32 be connected with an electric conductor, connects outside another
Connecting terminal 32 is connected with another electric conductor, it is also possible to obtain same action effect.
In addition, the electric conductor being connected with external connection terminals 32 is not limited in as the present embodiment by copper barred body
The electric conductor of composition, even the electric conductor being made up of lead also has same action effect.
Above with reference to having illustrated embodiments of the invention, but the present invention is not limited in above-described embodiment.In this hair
Various changes can be made in the range of bright technological thought, they belong to protection scope of the present invention.
