[0019] As shown in Figure 1 and Figure 2 The embodiment of the present application provides an external connection structure of a vehicle-mounted central control control line which avoids adding a fixing device, including a floating connector 300 between a vehicle-mounted host 100 and a decoder 200, the floating connector 300 includes a floating end 310 electrically connected to the vehicle-mounted host 100 and a fixed end 320 electrically connected to the decoder 200.
[0020] It should be noted that the structure of the vehicle-mounted host and the decoder and the functions realized thereby are not limited in any form in the present embodiment. In the prior art, the decoder is connected to the vehicle-mounted host for data transmission through a floating connector. Due to the complex working conditions of the vehicle, there are vibrations when the vehicle is started and jolts when the vehicle is running. The fixing through the plug-in mechanism of the floating connector cannot meet the requirements. Therefore, the decoder also needs to lock the shell carrying the decoder on the shell of the vehicle-mounted host through hardware to ensure the stability of the connection of the two ends of the floating connector, thereby ensuring the transmission and contact reliability. The floating connector between the decoder and the vehicle-mounted host needs to use a floating connector of a board-to-board connection mode, which is plugged into the floating end (male end) provided on the vehicle-mounted host from the fixed end (female end) provided on the decoder. In order to facilitate plugging and avoid misalignment, the existing technology of the installation auxiliary mechanism of the floating mechanism and the plug-in guide mechanism of the floating connector can better solve the problems in plugging. Therefore, the advantages and disadvantages and necessity of using the floating connector between the vehicle-mounted host and the decoder are not described in detail in the present embodiment.
[0021] Further, the external connection structure of the present embodiment further comprises an FFC flat cable 400, one end of which is provided with conductive contacts on both sides, which is plugged between the fixed end 320 and the floating end 310, and the conductive contacts on both sides are in contact with the conductive contacts 321 of the fixed end and the conductive contacts 311 of the floating end respectively, and the end is fixed by the pressure of the side wall of the plug-in slot of the fixed end 320 and the side wall of the plug-in part of the floating end 310. The other end of the FFC flat cable 400 extends outside between the vehicle-mounted host 100 and the decoder 200, and is electrically connected with a new decoder or other multimedia functional components.
[0022] The floating end 310 of the floating connector 300 has a plug-in slot 312 (which realizes floating with the elastic conductive contacts, and during PCB assembly, the offset amount can be corrected within a certain offset range to realize correct and accurate butt joint with the plug-in part of the fixed end), and a row of insulators 313 carrying conductive contacts are protruded in the middle of the plug-in slot 312, while the fixed end 320 of the floating connector is in the shape of a hollow groove, and the conductive contacts are arranged on the inner side wall of the groove, so that the conductive contacts on the inner side wall 322 of the groove are in contact with the conductive contacts on the insulators 313 protruded in the middle of the plug-in slot 312 to realize electrical connection. The end of the FFC flat cable 400 of the present embodiment is plugged between the conductive contacts on the inner side wall 322 of the groove and the conductive contacts on the insulators 313 protruded in the middle, and the end of the FFC flat cable is provided with conductive contacts on both sides, so that the signals between the two sides can be transmitted without affecting the data transmission between the vehicle-mounted host and the original decoder.
[0023] The skilled in the art can understand that there is also a small gap for elastic floating between the fixed end and the floating end of the floating connector, which is sufficient for the insertion of the end of the FFC flat cable, and after the insertion, the contact between the two ends of the floating connector can be made more firm due to the FFC flat cable. Of course, in the external structure of the utility model, the firmness and reliability of the line connection of the FFC flat cable to realize the new function are not only this, and the flat cable part of the FFC flat cable will be pressed between the fixed end and the floating end of the floating connector and between the vehicle host and the original decoder to provide more stable connection firmness in the following embodiments. It should be noted that the thickness and PIN number of the FFC flat cable are not limited in this embodiment, as long as the electrically conductive contact between the two ends of the floating connector can be inserted to realize electrical connection, and in actual application, the PIN number can also be greatly increased according to the actual use demand without affecting the overall connection structure.
[0024] In order to better understand the arrangement of the flat cable part of the FFC flat cable outside the insertion position between the electrically conductive contact of the fixed end and the floating end, in an optional embodiment, the FFC flat cable is a soft flat cable, the end thereof is inserted between the electrically conductive contact of the insertion slot and the insertion part, and the flat cable part adjacent to the end insertion position extends outward along the gap between the insertion slot profile and the insertion part profile, so that the insertion slot side wall and the insertion part side wall fix the end of the FFC flat cable.
[0025] That is, in the original floating connector, the insertion part outside wall 323 of the fixed end is surrounded and positioned by the insertion slot inside wall 314 of the floating end, and the end of the FFC flat cable 400 in this embodiment extends along the insertion slot inside wall 314 and the insertion part outside wall 323 after being inserted between the electrically conductive contact and being bent 410 adjacent to the flat cable part inserted between the electrically conductive contact. At this time, due to the clamping of the insertion slot inside wall 314 and the insertion part outside wall 323, the end double-sided electrically conductive contact position is firmly fixed between the electrically conductive contact of the insertion slot and the electrically conductive contact of the insertion part, and the electrically conductive contact between the three electrically conductive contacts is very stable and reliable.
[0026] Further, the first side 110 of the floating end 310 of the vehicle host 100 is fixed by hardware with the second side 210 of the fixed end 320 of the decoder 200, and the middle flat cable part of the FFC flat cable 400 is pressed between the first side 110 and the second side 210, and the pressed middle flat cable part 420 and the end inserted between the floating connector have a length reserved for keeping loose.
[0027] In the embodiment, the second side 210 of the decoder 200 (i.e. the side of the decoder shell attached to the vehicle host shell) is locked on the first side 110 of the vehicle host 100 (i.e. the side of the vehicle host shell attached to the decoder shell) by hardware or bolts, ensuring the stability of the floating connector between the vehicle host and the decoder. At this time, the first side 110 and the second side 210 can further clamp the FFC ribbon 400, increasing the installation stability of the FFC ribbon. And using the softness of the FFC ribbon, a proper length is reserved at the end and the clamped ribbon part, avoiding the ribbon being too tight, and reserving space for the other end or external accidental pulling force, further improving the connection stability of the conductive contact end of the floating connector.
[0028] In an optional embodiment, the end of the FFC ribbon is double-sided with A and B copper conductive gold fingers, which are inserted into the original floating connector, so that the input and output of the signal are transmitted from A to B inside the original floating connector, so as to avoid adding a new floating connector in the original vehicle to obtain a new transmission function.
[0029] In the traditional scheme, when a new vehicle multimedia function needs to be added, a converter or a new connector needs to be added to the floating end (male end of the floating connector) of the vehicle host, and the converter or the new connector needs to be customized with hardware or a frame to be locked on the shell of the vehicle host (because the center control structure and its position design are different for different vehicle models, when targeting different vehicle models, hardware and frames for fixing new connectors need to be customized, generally the hole positions are consistent with the decoder mounting hole positions, the customized hardware is locked on the vehicle host shell to fix the new connector, and the original decoder shell is locked on the customized hardware to fix the fixed end of the original decoder inserted into the new connector, i.e. the female end of the floating connector). That is, a converter with a connector female end connected to the vehicle host, a connector male end connected to the original decoder, and a connector circuit board fixed between the two, is needed, and then the ribbon of the connector circuit board is drawn out to the port for signal data transmission, which is used for new vehicle function insertion.
[0030] In the embodiment, the double-sided conductive contact of the FFC flat cable can realize the transmission of signals and data between the vehicle host and the decoder, avoid the installation of fixed devices, does not change the connection structure between the vehicle host and the decoder, and does not need professional operation. When an ordinary user wants to add a new vehicle function, the floating connector between the vehicle host and the decoder is disassembled, the end of the FFC flat cable is placed in the groove of the fixed end, and then the fixed end is inserted into the floating end. This does not affect the various guiding and positioning of the floating connector and the floating mechanism. Then, the other end of the FFC flat cable is stretched out between the gap between the insertion slot of the floating end and the insertion part of the fixed end, and the gap between the first side of the vehicle host and the second side of the decoder. Since the FFC flat cable is double-sided conductive, the required new function signals can also be transmitted to the corresponding device through the original connector, and the installation is convenient. The cost is low, and no additional connectors, hardware, etc. required for the new vehicle function are needed. The performance is stable, the compression of the floating connector and the compression of the vehicle host and the decoder make the FFC flat cable not easy to fall off and shift.
[0031] The above disclosed is only one or more preferred embodiments of the utility model, which is used to help understand the utility model concept, and does not limit the utility model in other forms. The skilled person in the art can make other equivalent or conventional means replacement schemes according to the limited features of the utility model, which still belongs to the scope covered by the utility model.
