Abstract

PURPOSE: To provide a connector device wherein two parts can be separated without any damage even when a relatively strong force is applied to a connector or a connector cable without the use of control members. CONSTITUTION: An electric insulating housing 1 is provided with at least one chamber 3 for accommodating a connector 2 having an insertion portion 15 and a connection cable 23. In the insulation portion 15, a lateral projection 19 works jointly with a recess 37 engaged therewith formed in the chamber 3. This connector device including the electric insulating housing 1 is furnished with at least one elastic element 17 having the lateral projection 19. A slant face 45 is provided as a side face in the opposite direction of insertion of each lateral projection 19. In this case, the slant face 45 is shaped making an acute angle with the inserting direction.

FIELD OF INDUSTRIAL APPLICATION The present invention comprises an electrically insulating housing having at least one chamber, the chamber of the housing configured to house a connector having an insertion portion and a connecting cable, the housing having at least one chamber. The present invention relates to a connector device including at least one elastic element having a lateral protrusion that engages and cooperates with a recess formed in the chamber.

Furthermore, the present invention relates to a connector applied to this connector device.

2. Description of the Prior Art A connector device of this type is described, for example, in Dutch Patent No. 7511843. The connector device described in Dutch Patent No. 7511843 is formed by two parts that fit together and are secured to each other by a locking mechanism that can be released via a control member. One part may be, for example, a connector provided with a connecting cable and fixed in the housing.

0004

However, instead of using a control member, some users have attempted to separate such two parts by applying a relatively large force to the connector or connector cable; Otherwise, damage may occur to one part of the connector. The object of the invention is therefore to obtain a connector device as described above which eliminates this drawback.

[0005]

[Means for Solving the Problems] In order to achieve this object, the connector device of the present invention is provided with an inclined surface on the side surface opposite to the insertion direction of each side protrusion, and this inclined surface is arranged with respect to the insertion direction. It is characterized by its shape forming an acute angle.

[0006]

This arrangement allows the connector to be removed from the housing with relatively little force. This reduces the risk of damage if the user disconnects the connector without using the control member. In a preferred embodiment of the connector device according to the invention, said direction of insertion is opposite to said direction of insertion, and the magnitude of the pulling force required to remove the connector from the housing is achieved by pulling said connecting cable out of said connector. less than the force required for Relatively little force is required to remove the connector from the housing, but wire clamping may be provided to maintain the connection of the cable to the connector even if the user removes the connector by pulling on the connecting cable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, preferred embodiments of the present invention will be described with reference to the drawings. The electrically insulating housing 1 shown in FIG. 1 has two chambers 3 that accommodate the connector 2 shown in FIG. Connector 2 is shown in more detail below with respect to FIG. The housing 1 is made of electrically insulating plastic, for example using injection molding. This type of housing 1 is disclosed in, for example, Dutch Patent Application No. 8802434 (Japanese Unexamined Patent Publication No. 2-14486).
It is suitable for use in the connector device described in No. 8). The housing 1 has connecting members 5, 7, 9 and a lateral projecting part 11 provided with a through hole 13 into which a connecting bolt (not shown) can be inserted.

The connector 2 shown in FIG. 2 comprises an insertion part 15 with at least one elastic element 17, which is provided with a lateral projection 19. A control member 21 is formed on each elastic element 17 . Connector has connection cable 2
3 will be provided. FIG. 3 shows the connector 2 attached to the housing 1. The connection cable 23 has three cores 25, 27, and 29, and connects to the contact members 31, 33, and 35 of the connector 2. The connector 2 is attached to the housing 1, and the contact member 31
, 33, 35 are connected to the connecting members 5, 7, 9 of the housing 1. The wall of the chamber 3 of the housing 1 is provided with at least one recess 37. When placing the insertion part 15 of the connector 2 in the chamber 3, the protrusion 19 engages in the recess 37. The connector 2 is locked into the chamber 3 by the engagement of the protrusion 19 and the recess 37. Therefore, the connector 2 is prevented from falling off from the housing 1 due to vibrations. The projection 19 can be removed by moving the control member 21 in the direction of the arrow 39 and the connector 2 can be pulled out of the housing 1 in the direction of the arrow 41.

[0009] Insertion direction of each protrusion 19 (indicated by arrow 43)
An inclined surface 45 forming an acute angle 47 with respect to the insertion direction 43 is provided on the opposite side surface. This is shown in detail in FIG. As a result, the connector 2 can be pulled out from the housing 1 with a relatively small force without using the control member 21. This is done because the user often pulls out this type of connector 2 from the housing 1 by pulling the connector 2 itself or the connecting cable 23. If this is not done, the connector 2 may be damaged or the connecting cable 23 may be disconnected from the connector 2.

[0010] Since a relatively small force is sufficient to extract the connector 2 from the housing 1, the risk of the cable becoming dislodged is reduced. Furthermore, wire clamping the connector 2 to the connecting cable 23 can withstand the pulling force (in the direction of arrow 41) required to disconnect the connector 2.
