Description

Technical Field

[0001] The utility model belongs to the field of connectors, and in particular relates to a floating connector component. Background Art

[0002] In order to achieve power and signal transmission between devices, two connectors are usually used to mate with each other. During the installation and connection of the connector, the connector needs to be plugged into the device and into each other. There are directional requirements during the plug-in process, so anti-reverse plug-in design is required, such as preventing reverse installation through key positions and color mark points or color mark slots, or preventing reverse installation through chamfer designs of different sizes. However, when using key positions, color marks, and color mark slots, it is necessary to check the color marks, and there are certain requirements for operating experience; the use of large and small chamfers to prevent reverse installation is feasible for non-floating connectors, but for floating connectors, since the connector can float, even if it is reversed, it is still possible to be reversed after the position floats.

[0003] In addition, the floating connector assembly consisting of a floating connector and an adapter connector needs to be guided during the plugging process to improve the installation efficiency of the connector and the connection reliability after installation. Utility Model Content

[0006] Its beneficial effects are: after setting the large and small chamfers for preventing reverse installation, the panel protrusion and the notch on the floating connector cooperate to prevent the floating connector from being reversed after the floating position is adjusted, and the floating of the floating connector is not affected; the guide head and the plug-in chamfer cooperate to play a guiding role in the plug-in process of the floating connector and the second connector, and then the shells of the two connectors can contact and guide, thereby forming a multi-level guide, which can ensure the normal plug-in and pull-out of the two connectors, reduce the insertion force of the connector, and increase the plug-in life of the connector.

[0007] The plug-in end of the floating connector is provided with a power jack and a signal jack; the plug-in end of the second connector is provided with a power contact and a signal contact; the plug-in ends of the two connectors are also provided with matching contact plug-in guide structures.

[0010] The beneficial effect is that corresponding guide structures are arranged according to different types of contact pieces, so that the guide structures are more targeted.

[0011] The height of the partition is greater than the height of the power contact, and the height of the annular partition is greater than the height of the signal contact.

[0013] The annular partition is arranged around the signal contact located on the center line of the power contact or the signal contact adjacent to the line.

[0014] The beneficial effect is that the electrical gap between the signal contact far away from the center line of the power contact and the power contact is larger, so there is no need to set up an annular partition, and the processing cost can also be reduced.

[0015] The guide heads are provided with two and are arranged opposite to each other, and the chamfers on the guide heads are arranged on the outer diameter surfaces of the guide heads.

[0016] The beneficial effect is that the symmetrically arranged guide heads can play a more stable guiding role and avoid the connector from being skewed.

DETAILED DESCRIPTION

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention in any way.

[0038] In the floating connector assembly proposed by the utility model, the floating connector serves as the first connector, and the non-floating connector serves as the second connector adapted thereto. This embodiment mainly aims at the installation of the floating connector on the installation panel of the equipment, and the plugging of the floating connector with the non-floating connector, and proposes an anti-reverse installation structure and a plug-in guide structure, thereby improving the accuracy and efficiency of connector installation and connection, as well as the reliability after connection.

[0039] The anti-reverse installation structure mainly involves Figure 1-3 The content shown.

[0040] One end of the floating connector 100 is a plug-in end for connecting to the mounting panel 200, and the other end is a plug-in end for connecting to the floating connector. Figure 1 As shown, the plug end is provided with a large chamfer 102 and a small chamfer 101 with different chamfer angles, and the mounting hole of the mounting panel 200 is also provided with corresponding large and small chamfers. During installation, the large and small chamfers of the floating connector 100 and the large and small chamfers of the mounting hole are matched to each other, and installation can be performed to a certain extent to prevent reverse installation. However, since there is a floating gap A between the floating connector and the hole wall of the mounting hole for the connector to float up and down and left and right, there is still a possibility of reverse installation if only the large and small chamfers are matched.

[0041] Further, such as Figure 2 As shown, a notch 103 is provided at one corner of the housing of the floating connector 100, and a panel protrusion 201 is provided on the mounting panel 200. When the connector is installed properly, the notch 103 can avoid the panel protrusion 201, and no interference occurs, and the connector can float normally. Figure 3 As shown, when the connector is reversely installed, the connector housing will interfere with the panel protrusion 201, and the connector cannot be installed in place, thereby achieving the function of anti-reverse installation.

[0042] The plug-in guide structure mainly involves Figure 4-8 Content shown.

[0043] like Figure 4 As shown, a guide head 104 is provided on each side of the edge of the plug-in end of the floating connector 100 for plugging with another connector, and the front end of the guide head 104 is processed with a chamfer. After the floating connector 100 is plugged into the matching non-floating connector 300, the non-floating connector 300 cannot move up and down or left and right relative to the floating connector 100. Figure 5 As shown, correspondingly, the end of the non-floating connector 300 used for plugging with the floating connector 100 is its plugging end, and an insertion chamfer 301 is provided at the plugging end of the non-floating connector 300, and the insertion chamfer 301 cooperates with the chamfer of the guide head 104. When the non-floating connector 300 and the floating connector 100 are plugged together, the guide head 104 on the floating connector 100 first contacts the insertion chamfer 301 on the edge of the shell of the plugging end of the non-floating connector 300, thereby guiding the plugging of the two connectors, and then the two connectors are guided by the shell contact of the plugging end so that the two connectors are aligned, and then the contacts begin to plug together.

[0044] It should be noted that the guide head used in this embodiment is cylindrical, and in other embodiments, a plate-shaped, conical structure or the like may also be used. Moreover, the number of guide heads is not limited to two, and may be more than two.

[0045] like Figure 6-7As shown, the plug-in guide structure also includes a contact plug-in guide structure for guiding the plug-in of the contacts. The contacts at the plug-in end of the non-floating connector 300 include a power contact 304 and a signal contact 305, and the signal contact 305 is in the form of a pin. Figure 6 As shown, there are three power contacts 304, corresponding to the positive pole, the negative pole, and the ground, respectively, and there are four signal contacts 305, which are arranged in a row between two power contacts 304. A partition 302 is arranged between two power contacts 304 without signal contacts 305, and the height of the partition 302 is slightly higher than the height of the power contacts 304. Two of the signal contacts 305 are adjacent to the center line between the power contacts 304, and an annular partition 303 is arranged around the two signal contacts 305, and the height of the annular partition 303 is higher than the signal contacts 305. Figure 7 As shown, the floating connector 100 is provided with corresponding power jacks 105 and signal jacks 107, as well as a partition slot 106 matched with the partition 302, and a partition ring groove 108 matched with the annular partition 303. During the contact engagement process when the non-floating connector 300 and the floating connector 100 are plugged in, the partition 302 first contacts the partition slot 106, and the annular partition 303 first contacts the partition ring groove 108, guiding the engagement of the power contact 304 with the power jack 105, and the signal contact 305 with the signal jack 107, respectively.

[0046] The height of the partition 302 is slightly higher than the height of the power contact 304. In addition to being able to contact the floating connector 100 before the power contact 304, it can also increase the electrical clearance and creepage distance between the power contact 304 to prevent the contact clearance from being less than the electrical parameter requirements. Similarly, the height of the annular partition 303 is greater than the height of the signal contact 305, and it can also increase the electrical clearance and creepage distance between the signal contacts 305. Since the electrical clearance between other signal contacts 305 and the power contact 304 is large, other signal contacts 305 do not need to be provided with annular partitions.

[0047] Similarly, the partition slot 106 and the partition ring groove 108 provided at the mating end of the floating connector 100 not only meet the connector mating function, but also increase the creepage distance between the floating connector contacts, thereby improving the safety performance of the product.

[0048] The utility model also proposes a contact fixing structure of a non-floating connector to fix and install the signal contact. Fig. 9 , 10As shown, the contact fixing structure includes an insulating plate 307 and a positioning spring 308. The insulating plate 307 is provided with mounting holes for mounting the signal contact 305, and the number of mounting holes is the same as the number of signal contacts 305. The insulating plate 307 is provided with positioning protrusions, and two positioning protrusions are symmetrically arranged. The positioning spring 308 is a spring claw, which is installed in the mounting hole and is used to be stuck on the stop surface of the signal contact 305 to prevent the signal contact 305 from retreating during the plug-in process.

[0049] The insulating housing at the plug-in end of the non-floating connector 300 is provided with a snap-fit ​​groove 309 for cooperating with the positioning protrusion on the insulating pressure plate 307. A sealing rubber pad 306 is also provided at the tail of the insulating housing, and a through hole is provided on the sealing rubber pad 306 for cooperating with the signal contact 305 and the power contact 304.

[0050] When fixing the signal contact 304, first install the positioning spring 308 into the mounting hole of the insulating pressure plate 307, and then install it together with the insulating pressure plate 307 into the insulating housing of the plug end of the non-floating connector 300. The positioning protrusion of the insulating pressure plate 307 is inserted into the buckle groove 309 of the insulating housing to lock the insulating pressure plate 307 and prevent the insulating pressure plate 307 from falling out. Then, insert the signal contact 305 into the mounting hole of the insulating pressure plate 307 until the positioning spring 308 is stuck on the stop surface on the signal contact 305 to prevent the signal contact 305 from being withdrawn. Finally, install the sealing pad 306 at the rear end of the insulating housing. The structure after installation is as follows. Fig.10 shown.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can be modified or replaced by equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
