Detailed Description

Embodiments of the present invention are exemplarily described below. As those skilled in the art will appreciate, the illustrated embodiments may be modified in various different ways without departing from the inventive concept. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive. In the following, the same reference numbers generally indicate functionally identical or similar elements.

Fig. 1 schematically shows a connection assembly 1 according to an embodiment of the invention. The connecting assembly 1 comprises a first connecting member 10 and a second connecting member 20. They can be plugged into one another in the direction of the hollow arrows shown in fig. 1.

The first link 10 has a first link body 101 and an arm 104 attached thereto. The arm portion has a constant thickness. Here, the first link body 101 and the arm portion 104 are integrally molded. In fig. 1, a pair of arm portions 104 are shown oppositely disposed on a first connector body of an approximately square shape. Of course, the number and location of the arms 104 may be set as desired. The arms are flexible and are also configured with grommets 105 at the ends of the arms, as will be explained further below.

The second connector 20 has a second connector body 201 and a latch tongue 204 attached thereto. The locking tongues 204 project from the second connector body 201 and are arranged opposite one another on the second connector body 201, likewise in a manner adapted to the arrangement of the arms 104 of the first connector. The body of the second connector body 201 has a receiving cavity 202 formed therein for receiving the body 101 of the first connector. To this end, the shape of the outer contour cross section of the first connector body 101 at the connection side is at least partially matched to the shape of the inner contour cross section of the receiving cavity 202 in the second connector body 201, in order to ensure a highly precise positional connection of the first connector and the second connector. Preferably, the respective cross section is a profiled surface, for example a square surface with an inverted corner, which makes a fail-safe connection possible.

The first connecting member 10 and the second connecting member 20 also have at least one pair of faces which abut against each other in the connected state to define the mounted state. At least one latching means 108 is provided on the circumferential outer side of the body of the first connecting part 10, which latching means has a spring property, wherein a gap 109 is provided between the latching means 108 of the first connecting part and the circumferential outer side. A recess 110 is formed on the side of the card 108 facing the outer wall (see fig. 3). At least one projection 210 is also formed on the circumferential outer side of the second connecting piece 20. During insertion, a portion of the circumferential wall of the second connecting part 20 can be placed in the recess 109 between the latching tab 108 of the first connecting part and the circumferential outer side, and the latching tab 108 can be elastically deformed outward until the projection 210 is received in the recess 110 and the latching tab 108 is reset. When the insertion is completed, at least one of the respective surfaces of the recess 110 and the projection 210 rests against one another, as is apparent in the sectional illustration in fig. 3.

For better guiding the card 108, the second connector body 201 is configured at its circumferential outer side with a pair of guide portions 208, and the projection 210 is in a space 209 formed by the guide portions 208.

Of course, the contact surfaces of the first connecting part 10 and the second connecting part 20 can also be formed by the end face of the first connecting part 10 facing the second connecting part 20 during the insertion process and the bottom face of the receiving space 202 of the second connecting part 20, respectively. When the plugging is completed, the two faces are in contact with each other.

When the first connector 10 and the second connector 20 are connected, the arm 104 of the first connector 10 may be deflected in the direction of the latch 204 of the second connector 20, so that the latch 204 passes through the grommet 105 provided in the arm 104. In this case, the bottom 206 of the locking tongue 204 comes into contact with the edge 106 of the button hole 105 and, in cooperation with the aforementioned contact surface, maintains a secure permanent connection of the two connecting elements. To this end, the grommet 105 may be a locking structure and the tongue 204 a mating locking structure. In fig. 2 and 4, an initial state in which the arm portion is horizontal and a connected state in which the arm portion is upright are shown.

At the transition between the arm 104 and the first connector body 101, a material thinning 107 is configured to enable a flexible connection therebetween. A cross-sectional illustration of the material thinning 107 is schematically shown in fig. 5. It can be seen that two recesses are formed at the transition, wherein the recess on the outer side of the closure has a greater depth than the recess on the inner side of the closure, for example the recess on the outer side of the closure has a substantially semicircular cross section and the recess on the inner side of the closure has a flat bottom surface, wherein the recess on the outer side of the closure has a radius R of 0.75mm, the recess on the inner side of the closure has a length L of 1.5mm and the material thinning 107 has a thickness T of 0.3 mm. The recess on the inner side can be rounded between its bottom and its side, the chamfer having a dimension of, for example, 0.1 mm. Through the scheme, the material on the outer side of the closure part can be subjected to tensile stress and strain in the closing process, and the compressive stress and strain on the material on the inner side can be kept within the range smaller than the yield stress of the material, and excessive stress concentration at the position can be prevented, so that cracking is prevented, and the service life of the flexible connecting part is effectively prolonged.

Of the above-described connectors, particularly those provided with the material thinning 107, may be injection molded from a plastic, such as polypropylene PP or polyethylene PE.

The first connection element 10 and the second connection element 20 can also be provided with contact elements, which are formed, for example, from an electrical conductor, such as copper. In the figures, it can be seen that 8 first electrical conductors 103 are provided in the first connection piece 10, one end of which is inserted into the opening 102 in the first connection body 101 and which can have a cylindrical configuration, for which purpose a female contact is formed. The second connector 20 has 8 second conductors 203, which are cylindrical, square cylindrical or flat in shape, and thereby form male contacts. In the inserted state, the male contact and the female contact form a contact pair, and the electrical connection is completed by the insertion of the female contact and the male contact. The first connecting part can be regarded as a male plug and the second connecting part as a female plug.

It is to be noted herein that although it is shown in the drawings that the arm is provided at the male head and the tongue is provided at the female head, and only a pair of the arm and the tongue is shown, the bodies to which the arm and the tongue are attached may be exchanged, that is, the tongue is provided at the male head and the arm is provided at the female head. Of course, a hybrid arrangement is also possible. The number and the arrangement positions of the two can be determined according to requirements.

The present invention is not limited to the above configuration, and various other modifications may be adopted. While the invention has been described with respect to a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that other embodiments can be devised which do not depart from the scope of the invention as disclosed herein. Accordingly, the scope of the present invention should be limited only by the attached claims.
