  By the way, the electrical connection structure in this type of electromagnetic counter is not limited to that shown in FIGS. 12 to 14, and there are various modes. However, as described above, the connection projecting outside the cover member c is generally used. There are two types: a type in which terminals are directly connected to a wiring pattern formed on an electromagnetic counter installation base by solder and a type in which lead wires are connected to connection terminals. In the type limited to lead wire connection, the outer end of the connection terminal may protrude to the outside or the inside of the cover member, and the tip of the lead wire should be soldered to the outer end of the connection terminal. It has become.

However, such a conventional electrical connection structure has the following problems.
That is, a lead wire having a predetermined length is connected by soldering to an electromagnetic counter that is being miniaturized, so that the lead wire becomes an obstacle during the soldering operation and the soldering itself is a precise operation. Therefore, it takes time to assemble the electromagnetic counter and affects the manufacturing cost.
Usually, a connector is connected to the other end of the lead wire. However, in order to solve the problems caused by the soldering operation described above, an electromagnetic counter in which the lead wire with the connector is soldered to the connection terminal is actually installed in advance. It is assembled in large quantities so that a large number of products can be delivered in a short time according to customer orders. However, due to changes in specifications on the precision instrument side to which the electromagnetic counter is attached, the standard and shape of the connected part to which the connector is connected are changed, and the connector must be changed, or directly on the installation base as shown in FIG. If the soldering type is changed, it may not be possible to meet the demand for quick delivery.

  The present invention has been made in view of such a conventional situation. The purpose of the present invention is to connect a lead wire to a connection terminal for supplying electric power to an electromagnet or an illumination means.

Thus, one end of the electromagnet lead wire can be removably inserted into the frame member or the cover member, and the engagement protrusion protruding from the side surface of the pin contact is elastically engaged with the frame member or the cover member. A recess is provided (claim 1).

  According to such a configuration, when the pin contact is inserted into the outer end portion of the electromagnet connection terminal, the locking projection protruding on the side surface of the pin contact is elastically engaged with the engagement recess, so that the electromagnet lead wire Can be connected with a single touch. Therefore, when connecting the lead wires, soldering is not necessary, and by preparing a plurality of types of lead wires having connectors of different standards connected to the other end in advance, the precision instrument side to which the electromagnetic counter is attached is prepared. Depending on specification changes, lead wires with corresponding connectors can be selectively connected, and electromagnetic counters with connector-attached lead wires can be delivered in a short period of time according to customer requirements. it can.

The above-described electrical connection structure is not limited to the use as an electromagnet connection terminal, but can also be used as a lighting means connection terminal.
That is, the frame member is further equipped with illumination means for illuminating the display unit, and illumination means connection terminals for supplying power to the illumination means are arranged along the side surfaces of the frame member. In this case, one end of the lead wire for illumination means can be removably inserted into the outer end portion of the connection terminal for illumination means by a pin contact provided at one end of the lead wire for illumination means, and the frame It is preferable that the member or the cover member is provided with a second engaging recess in which a locking projection protruding on a side surface of the pin contact of the illuminating means lead wire is detachably elastically engaged (Claim 2).

  In this case, in the electromagnetic counter provided with the illuminating means, when connecting the lead wire to the illuminating means connection terminal, soldering is not necessary, and a plurality of lead wires having connectors with different standards connected to the other end are provided in advance. By preparing the seeds, it is possible to selectively connect a lead wire having a corresponding connector according to a change in specifications on the precision instrument side to which the electromagnetic counter is attached. Therefore, the electromagnetic counter with built-in illumination means to which the lead wire with the connector according to the customer's request is connected can be delivered in a short period of time.

It is preferable that the outer end portion of the connection terminal described above protrudes to the outside of the cover member and can be soldered to an external wiring such as a printed wiring.
In this case, the lead wire can be connected to the connection terminal by a one-touch method as described above, and the connection terminal can be directly soldered to a printed wiring (external wiring) for an installation base.

  In the present invention, the number wheel of the number wheel is not necessarily limited. However, the number wheel of the least significant digit that rotates by a predetermined angle as the ankle swings and the required number of transmission gears formed on the side surface. Are generally used, and a pinion that interposes between these number wheels and carries a carry is used in general, and it goes without saying that such a mode is included in the present invention.
