Abstract
The connection member comprises an electrically insulating housing (1) with at least one chamber (3). The chamber (3) accommodates a connector (2) provided with an insertion portion (15). The insertion portion (15) comprises at least one resilient element (17) on which there is provided a lateral projection (19) which cooperates with a recess (37) in the chamber (3) in order to secure the connector (2) in the housing (1). At its side which is remote from the insertion direction (43), each projection (19) is provided with an inclined face (45) which encloses an acute angle (47) with respect to the insertion direction (43).
Description
- The invention relates to a connection member, comprising an electrically insulating housing provided with at least one chamber which accommodates a connector comprising an insertion portion and a connection cable, the insertion portion being provided with at least one resilient element which comprises a lateral projection which cooperates with a recess in the chamber.
- The invention also relates to a connector suitable for use in a connection member in accordance with the invention.
- A connection member of the kind set forth is known from Netherlands Patent Specification No. 7511843 laid open to public inspection. The connection member disclosed therein is formed by two portions which fit one into the other and which are secured to one another by way of a locking mechanism which can be released via a control member. One of the portions may be, for example, a connector which is provided with a connection cable and is secured in a housing.
- Some users, however, tend to separate such portions by exerting a comparatively large force on the connector or on the connection cable instead of using the control member, thus damaging one of the portions.
- It is an object of the invention to provide a connection member of the kind set forth in which said drawback is mitigated.
- To achieve this, the connection member in accordance with the invention is characterized in that at its side which is remote from the insertion direction, each projection is provided with an inclined face which encloses an acute angle with respect to the insertion direction.
- As a result of the described step, the connector can be removed from the housing using a comparatively small force. This reduces the risk of damaging should the user remove the connector without using the control member.
- A preferred embodiment of the connection member in accordance with the invention is characterized in that the magnitude of a pulling force which is directed so as to oppose the insertion direction and which is necessary for removing the connector from the housing is smaller than the force required for pulling the connection cable loose from the connector. Despite the comparatively small force required for removing the connector from the housing, moreover the wire clamping is such that the cable remains connected to the connector even if the user were to remove the connector by pulling the connection cable.
- The invention will be described in detail hereinafter with reference to the drawing.
- Figure 1 is a front view of an embodiment of an electrically insulating housing suitable for use in a connection member in accordance with the invention,
- Figure 2 is a side elevation of an embodiment of a connector suitable for use in a connection member in accordance with the invention,
- Figure 3 is a plan view of an embodiment of a connector as shown in Figure 2 which is arranged in a chamber of the electrically insulating housing shown in Figure 1, the chamber and a part of the connector being shown in a cross- sectional view, and
- Figure 4 is a detailed plan view of a part of the connector at the area of the lateral projection.
- The electrically insulating
housing 1 shown in Figure 1 comprises twochambers 3 for receiving aconnector 2 as shown in Figure 2. Theconnector 2 will be described in detail hereinafter with reference to Figure 2. - The
housing 1 can be made of an electrically insulating plastics, for example using an injection moulding process. Ahousing 1 of this kind is suitable, for example for use in a connection member as disclosed in Netherlands Patent Application Nr. 8802434 (PHN 12.692). Thehousing 1 comprisesconnection members portions 11 with through-holes 13 wherethrough connection bolts (not shown) can be inserted. - The
connector 2 shown in Figure 2 comprises aninsertion portion 15 which comprises at least oneresilient element 17 on which alateral projection 19 is provided. Acontrol member 21 is formed on eachresilient element 17. The connector is also provided with aconnection cable 23. - Figure 3 shows a
connector 2 mounted in thehousing 1. Theconnection cable 23 comprises threecores contact members connector 2 is mounted in thehousing 1, thecontact members connection members housing 1. The wall of thechamber 3 of thehousing 1 is provided with at least onerecess 37. When theinsertion portion 15 of theconnector 2 is arranged in thechamber 3, theprojection 19 engages therecess 37. Theconnector 2 is locked in thechamber 3 by cooperation between theprojection 19 and therecess 37. Theconnector 2 is thus prevented from dropping out of thehousing 1 under the influence of vibrations. Theprojection 19 is removed from therecess 37 by moving thecontrol member 21 in the direction of thearrow 39, so that theconnector 2 can be removed from thehousing 1 in the direction of the arrow 41. - The side of each
projection 19 which is remote from the insertion direction, indicated by thearrow 43, is provided with aninclined face 45 which encloses anacute angle 47 with respect to theinsertion direction 43. This is shown in detail in Figure 4. As a result, a comparatively small force suffices to remove theconnector 2 from thehousing 1, without utilizing thecontrol member 21. This is because in many cases a user removes aconnector 2 of this kind from thehousing 3 by pulling theconnector 2 itself or theconnection cable 23. This could damage theconnector 2 or could detach theconnection cable 23 from theconnector 2. - Because a comparatively small force suffices to remove the
connector 2 from thehousing 1, the risk of detachment of the cable is minimized. Moreover, the wire clamping of theconnector 2 on theconnection cable 23 is realized so that it is capable of withstanding the pulling force (in the direction of the arrow 41) required to remove theconnector 2.
Claims (3)
1. A connection member, comprising an electrically insulating housing provided with at least one chamber which accommodates a connector comprising an insertion portion and a connection cable, the insertion portion being provided with at least one resilient element which comprises a lateral projection which cooperates with a recess in the chamber, characterized in that at its side which is remote from the insertion direction each projection is provided with an inclined face which encloses an acute angle with respect to the insertion direction.
2. A connection member as claimed in Claim 1, characterized in that the magnitude of a pulling force which is directed so as to oppose the insertion direction and which is necessary for removing the connector from the housing is smaller than the force required for pulling the connection cable loose from the connector.
