[Detailed description of the invention] [Industrial application field] The present invention relates to electrical connectors for solenoid coils.

BACKGROUND OF THE INVENTION The contact member openings of such electrical connectors are designed to accommodate the shape of the male contact member for use with electrical appliances and other connectors having a particular shape and arrangement of male contact members. It has a predetermined arrangement. The specific shape of the male contact element avoids accidental contact with incompatible parts and unintended contact with other connectors and electrical appliances, thus preventing malfunctions and flight cancellations. can.

[Problem to be Solved by the Invention] In such electrical connectors used for parts such as solenoid coils, when improvements are made or parts are replaced for installation or repair, The shape of the contact part of a new part may change due to changes in Standard DIN
43650 has been introduced. Further, electrical appliances including parts imported from overseas may have contact portions of different standards, that is, contact members of different shapes.

In such cases, it may be necessary to replace not only some parts, but all parts of the appliance.

Not only is this replacement complex, but rewiring and repositioning electrical connectors for trials is also a very time consuming and complex task.

In order to solve this problem, German Patent Publication No. 3
, 625, 675A, an electrical connector consisting of a case and a variety of interchangeable connector cores adapted to different shapes has already been proposed. Disadvantages of this electrical connector are its high technical complexity and high manufacturing costs.

Furthermore, it is necessary to secure a wide variety of connector cores so that they can be used at all times.

One of the objects of the present invention is to provide an electrical connector that can be matably connected to other electrical appliances or other electrical connectors having contact members of various shapes without an adapter.

[Means for Solving the Problems] In order to achieve the above object and other objects, an electrical connector for a solenoid coil of the present invention (a connector case,
a connector core having an upwardly facing connector outer end surface that is fitted and mounted in the connector case and has a contact member opening disposed in a first configuration that is compatible with a male contact member of an appliance and other connector; an electrical connector comprising: a contact element provided in a receptacle of a contact member opening in a connector core and having a connecting element attached for connecting a conductor; The first area provided with the opening further includes an opening for a contact member having at least a second shape, and each contact element is arranged in the recess of the contact member opening having the first and second shapes. It is characterized by

[Function] In order to make the electrical connector of the present invention compact, especially when the contact members have similar shapes (at least the first shape contact member opening and the second shape contact member opening are configured such that they overlap in their respective cross sections. In this case, in order to simplify the shape and contact contact elements of various shapes, the overlapping openings for the contact members are each slot-shaped, and the common part of the slots is is provided with a contact element.

However, it is also possible to provide at least one opening for a contact element of the first shape in the vicinity of an opening for a contact element of the second shape. The contact elements each have at least two resilient projections, which projections are respectively located in the recesses of the two contact member openings. In this case as well, since the shape of the contact element is relatively simple, electrical contact is made at the same time in the adjacent contact member openings.

If the contact element is constituted by an elastic plier-like member or a single plier-like member, sufficient contact with the male contact member is achieved. This pliers-like member elastically pinches each male contact member from both sides.

In order to reduce the time and ease of assembly and pre-assembly of the connector core, the connector core has a stop that locks into the connector case. With this fastener, the connector core can be easily placed in a predetermined position with one touch by simply inserting it into the connector case. The stopper is constituted by a stop pin provided on the surface of the connector core opposite to the outer end surface of the connector. This allows for simple and reliable contact with the stop.

The inside of the fixing pin is hollow and passes through the connector, so insert the fixing screw here to securely fix the connector core inside the connector case, and also to attach the entire connector to electrical equipment and the connector that will be contacted. can.

Further, the connector cores are inserted into the connector case at different angles such as 180° or 90° with respect to each other, with the outer end faces of the connectors facing upward. In this case, for example, the wire holding means (such as the wire holding means) connected to the electrical connector may be attached from various directions irrespective of the arrangement of the male contact members of the electrical appliance.
