Description

Technical Field

[0001] The utility model relates to the technical field of FCN branching terminals, in particular to an FCN interface connector direct wiring type branching terminal module. Background Art

[0002] The traditional FCN interface usually uses a prefabricated cable with a unique connector on the head end and then transfers it to the terminal block. The connection and wiring are then carried out on a dedicated terminal block according to actual needs, or a dedicated cable is made in advance for wiring. This results in the inability to change the usage and wiring form at any time according to the on-site conditions during the connection process of the FCN interface connector. In addition, the branch terminals of the existing FCN interface connector are mostly fixed with a quick-plug structure during connection. When plugging and unplugging the wiring, it is easy for the terminal head to get stuck, causing the PCB board of the branch terminal module to be pulled, thereby causing damage to the FCN interface connector. In view of this, an in-depth study was conducted on the above-mentioned problems, resulting in this case. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides an implementation scheme: when connecting a modern FCN interface, it is often necessary to prefabricate a dedicated wiring cable when wiring. At the same time, the flexibility during use is low when wiring. If a branch terminal is used, the above problem can be effectively solved. However, the existing branch terminal is connected to the FCN interface by welding and mounting on a PCB board 3. In this way, when plugging and unplugging the quick plug, when plugging and unplugging the wiring of the branch terminal, it is easy to cause excessive pulling force on the branch terminal and the PCB board 3 due to wiring jam, causing damage to the PCB board 3.

[0021] In view of the above problems, the present application discloses an FCN interface connector direct wiring type branching terminal module, which is composed of an upper shell 1 and a lower shell 2. The upper shell 1 and the lower shell 2 are connected by a buckle cover structure. A PCB board 3 is arranged between the upper shell 1 and the lower shell 2. A quick plug-in terminal 4 is connected to the PCB board 3. A 40p connector 5 is connected to the back of the PCB board 3. The external FCN wiring is connected through the 40p connector 5. The quick plug-in terminal 4 corresponds to the 40p connector 5 one by one, and then the quick plug-in terminal 4 is used to flexibly connect with the external wiring;

[0022] It should be noted that, in order to facilitate wiring, the interface of the quick-plug terminal 4 needs to be exposed outside the upper shell 1, and the interface of the 40p connector 5 also needs to be exposed outside the bottom shell;

[0023] Furthermore, in order to buffer the quick-plug terminal 4 and the PCB board 3, and to avoid the problem that the rigidly mounted PCB board 3 is pulled and damaged when plugging and unplugging the quick-plug terminal 4 during the wiring and plugging process, specifically, a buffer middle frame 6 is provided on the lower shell 2, and the buffer middle frame 6 surrounds and wraps around the outside of the PCB board 3 and has a pair of first limiting grooves 7 corresponding to the redundant length on both sides of the PCB board 3, and a pair of second limiting grooves 8 are provided on the upper shell 1 at positions corresponding to the pair of first limiting grooves 7; two pairs of V-shaped buffer sheets 9 are fixedly provided on both sides of the PCB board 3 by screws, and the ends of the two pairs of V-shaped buffer sheets 9 are respectively in contact with the pair of first limiting grooves 7 and the pair of second limiting grooves 8;

[0024] In the specific implementation process, the buffer middle frame 6 extends from the lower shell 2 and serves as a guide mechanism connecting the upper shell 1 and the installation position of the buffer component. Specifically, a V-shaped buffer sheet 9 is used as a buffer member. The V-shaped buffer sheet 9 is a metal elastic material. The middle section of the V-shaped buffer sheet 9 is in contact with the PCB board 3, and the raised end of the V-shaped buffer sheet 9 is clamped with the first limit groove 7 and the second limit groove 8. After the upper shell 1 and the lower shell 2 are buckled, the V-shaped buffer sheet 9 will be slightly deformed to provide a certain supporting force to achieve pushing and limiting. At the same time, when the quick-plug terminal 4 is connected and unplugged, if a jamming problem is encountered, the V-shaped buffer sheet 9 can be further deformed to alleviate this force, reduce the stress deformation of the PCB board 3, and be observed by the user along with the slight displacement of the quick-plug terminal 4, so as to quickly re-change the angle for plugging and unplugging.

[0025] As a preferred solution, further, the two pairs of V-shaped buffer sheets 9 are metal spring sheets made of beryllium copper material and an insulating layer is provided on the side in contact with the PCB board 3. Beryllium copper material is easy to obtain and has good elastic effect.

[0026] As a preferred solution, further, a pair of mounting holes is opened on the upper shell 1, a corresponding pair of through holes is opened on the PCB board 3, and two pairs of jacks are opened at positions corresponding to the pair of through holes on the two pairs of V-shaped buffer sheets 9.

[0027] As a preferred solution, further, a pair of threaded columns 10 are provided on the lower shell 2 corresponding to a pair of mounting holes, and a pair of connecting screws 11 are provided from the pair of mounting holes, passing through a pair of through holes and two pairs of plug holes connected to the pair of threaded columns 10. A pair of connecting screws 11 pass through the through holes and the plug holes and are connected to the threaded columns 10, so that the connection between the upper shell 1 and the lower shell 2 is further stabilized. It should be noted that the plug holes, the through holes and the connecting screws 11 are all clearance fits.

[0028] As a preferred solution, further, the side wall of the lower shell 2 is provided with a protrusion 12, and the side wall of the upper shell 1 is provided with a groove 13 matching the protrusion 12, which plays a guiding and limiting role in the connection between the upper shell 1 and the lower shell 2.

[0029] As a preferred solution, further, the 40p connector 5 is compatible with the FCN connector interface.

[0030] From the above, it can be generally known that the FCN interface connector direct wiring type branch terminal module adopts the method of connecting the quick-plug terminals and the FCN interface connector on both sides of the PCB wiring board respectively, so that the wiring line type of the FCN interface connector is more flexible, and the quick-plug terminals 4 are adapted to be provided with a buffer middle frame 6 and a corresponding buffer component to limit and buffer the PCB board 3, so as to avoid damage to the PCB board 3 during use due to the deformation of the wiring of the quick-plug terminals during the plug-in and unplugging process.
