detailed description

The invention will be described in detail below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1 , an embodiment of the present invention provides a connection apparatus, including:

a socket 6 disposed on the base 5, and a plug 7 mated with the socket 6;

The socket 6 includes a floating portion 61 and a connecting portion 62. The floating portion 61 is sleeved in the cavity 51 of the base 5, and drives the connecting portion 62 to expand and contract along the cavity 51 when subjected to an external force; the connecting portion 62 and the floating portion 61 is connected and extends outside the cavity 51 for mating connection with the plug 7;

The base 5, the socket 6 and the plug 7 are respectively provided with interfitting alignment mechanisms 8 for guiding the plug 7 into the socket 6.

The connecting device provided by the embodiment of the present invention, the socket 6 includes a floating portion 61 and a connecting portion 62; the floating portion 61 is sleeved in the cavity 51 of the base 5, and drives the connecting portion 62 to creep along the cavity 51 when subjected to an external force; The connecting portion 62 is connected to the floating portion 61 and extends outside the cavity 51 for mating connection with the plug 7, so that when the plug 7 is inserted into the connecting portion 62 of the socket, the connecting portion 62 can be driven by the floating portion 61. The pedestal 5 is relatively stretched, thereby effectively buffering assembly errors with a small space and a low cost, thereby effectively improving the quality of the device connection.

It should be noted that the creeping range of the floating portion 61 in the cavity 51 is generally small, and only the assembly error can be compensated for. In order to make this peristalsis more controllable, it is preferable to provide a damping portion between the floating portion 61 of the socket 6 and the wall of the cavity 51 of the base 5 in order to increase the resistance of the floating portion 61 to creep in the cavity 51, This makes the creeping slower and the position more controllable. Optionally, the damper portion may include a rubber pad or the like that is sleeved on the floating portion of the socket, which is not limited by the embodiment of the present invention.

In an embodiment of the present invention, in order to limit the creep range of the floating portion 61 of the socket 6 in the cavity 51 of the base 5, a latching mechanism is further disposed between the floating portion 61 of the socket 6 and the base 5, Such as limit pins or circlips.

In particular, the alignment mechanism 8 can be various mechanisms that enable the plug 7 to be accurately inserted into the socket 6, and embodiments of the present invention are not limited thereto. For example, in one embodiment of the present invention, the alignment mechanism 8 may include a base positioning hole provided on the base 5, a connection positioning hole provided at the connection portion 62 of the socket 6, and a connection hole provided on the plug 7. The positioning post; when the plug 7 is connected to the socket 6, the positioning post continuously penetrates the base positioning hole and the connection positioning hole.

In an embodiment of the present invention, the number of the positioning posts and the positioning holes may be multiple and the distribution is not limited. Generally, the more the number, the more uniform the distribution, and the greater the accuracy of the alignment. For example, in one embodiment of the present invention, the number of the base positioning holes, the connection positioning holes, and the positioning posts is three, and the lines of the three sets of alignment mechanisms may form a triangle.

In order to improve the alignment accuracy of the alignment mechanism 8, preferably, the length of the positioning post may be set larger than the length of the plug 7. Thus, in the process of inserting the plug 7 into the socket 6, before the plug 7 contacts the socket 6, the positioning post has first contacted the connection positioning hole, and only when the positioning post is smoothly inserted into the connection positioning hole, the plug 7 The socket 6 can be smoothly inserted, thereby further improving the operability in assembling the connecting device.

The connecting device provided by the present invention will be described in detail below by way of specific embodiments.
