Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector assembly. Background Art

[0002] The connector usually needs to be fixed on the PCB surface by auxiliary structures to form a reliable connection. There are two common fixing forms. One is to add a fixed frame structure. The fixed frame is fixed on the PCB surface by SMT or other means. The fixed frame is generally designed with a card slot, and the connector housing is designed with a buckle. After the two are buckled together, the connector is fixed on the PCB to form a reliable connection. This solution has high requirements for the fixed frame structure and has many installation processes. The other is to add a load backplane structure. For example, when the groundless high-speed cable connector disclosed in the Chinese invention patent application document with application publication number CN116598805A is installed on the surface of the PCB board, the groundless high-speed cable connector is connected to the external connector, PCB board, insulating diaphragm and load backplane by locking screws. The load backplane is installed on the back of the PCB board, and the insulating diaphragm is between the load backplane and the PCB board to prevent the load backplane and the PCB board from directly contacting and causing a short circuit. This solution can solve the defects of the first installation method, but it will bring new defects, because the connector is usually installed on the surface of the PCB board, and the load backplane needs to be installed on the back of the PCB board. However, there is usually not enough space on the back of the PCB board to hold down the load backplane, which makes it inconvenient to tighten the locking screws. Utility Model Content

[0003] The utility model aims to provide a connector assembly to solve the problem that the load back plate is inconvenient to assemble when the existing connector is installed on the surface of a PCB board.

[0005] A connector assembly comprises a connector and a load back plate. The load back plate is provided with a bonding structure, and the bonding structure is used for bonding to the back side of a PCB board to fix the load back plate on the back side of the PCB board.

[0006] Furthermore, the bonding structure is an insulating film with double-sided adhesive, one side of the insulating film is bonded to the load back plate, and the other side is used for bonding and fixing with the PCB board.

[0007] Furthermore, a positioning structure for positioning and cooperating with a positioning hole on the PCB board is provided on the load back plate.

[0008] Furthermore, a positioning column protruding from the surface of the load back plate is provided on the load back plate, and the positioning column constitutes the positioning structure.

[0009] Furthermore, the connector has a positioning boss for positioning and cooperating with a positioning hole on the PCB board, and the positioning boss and the positioning column on the load back plate share the positioning hole.

[0010] Furthermore, the connector assembly also includes a locking screw, and the connector and the load back plate are connected together by the locking screw.

[0011] Furthermore, the connector includes a shell and a cable assembly installed in the shell, the shell is electrically connected to the shielding structure of the cable assembly, and the shell is electrically connected to the load backplane through a locking screw.

[0012] Beneficial effect: The connector assembly of the utility model is improved on the basis of the existing connector assembly. By setting a bonding structure on the load backplate, when the connector is installed on the surface of the PCB board, the load backplate can be bonded to the back of the PCB board through the bonding structure in advance, and then the connector can be fixed to the surface of the PCB board. At this time, there is no need to consider the problem of pressing the load backplate, thereby solving the defect of the inconvenience of installing the load backplate when the connector is installed on the surface of the PCB board, and the assembly operation is more convenient.

[0017] The connector assembly of the utility model provides an adhesive structure on the load back plate, and the load back plate can be adhered to the back of the PCB board through the adhesive structure. In this way, there is no need to consider the problem of pressing the load back plate when fixing the connector to the surface of the PCB board, thereby solving the defect of the inconvenience of installing the load back plate.

[0018] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0019] Embodiment 1 of the connector assembly of the utility model:

[0020] like Figure 1 As shown, the connector assembly includes a connector 1 and a load back plate 5. When in use, the connector 1 and the load back plate 5 are respectively installed on the front and back sides of the PCB board 3 and connected together by locking screws 2. There are four locking screws 2, which are respectively arranged at the four corners of the connector assembly. The load back plate 5 is provided with an adhesive structure, which is used to be bonded to the back side of the PCB board 3 to fix the load back plate 5 on the back side of the PCB board 3.

[0021] like Figure 2-3 As shown, the bonding structure is specifically an insulating film 4 with double-sided adhesive, one side of the insulating film 4 is bonded to the load back plate 5, and the other side is used to bond and fix to the PCB board 3. A protective film is provided on the surface of the insulating film 4. After the protective film is torn off to expose the adhesive surface, it can be bonded and fixed to the PCB board 3. The insulating film 4 is provided with an avoidance hole for avoiding the locking screw 2. The insulating film 4 is located between the load back plate 5 and the PCB board 3, which can prevent the load back plate 5 and the PCB board 3 from directly contacting and causing a short circuit. Of course, in other embodiments, when there is no wiring on the back of the PCB board, but the wiring is internal, the insulating film may not be provided. At this time, an adhesive layer may be provided on the mounting surface of the load back plate, and the load back plate is directly bonded to the back of the PCB board. At this time, the adhesive layer on the surface of the load back plate constitutes the bonding structure.

[0022] In order to ensure that the load back plate 5 is accurately installed on the back of the PCB board 3, a positioning structure for positioning and matching with the positioning hole 302 on the PCB board 3 is provided on the load back plate 5. Figure 3 As shown in , the PCB board 3 is a rectangular plate, and screw through holes 301 for the locking screws 2 to pass through are provided near the four corners of the PCB board 3, and two positioning holes 302 are provided near the left and right edges of the middle area of ​​the PCB board 3. The load back plate 5 is a rectangular plate, and two positioning posts 501 protruding upward from the surface of the load back plate 5 are provided near the left and right edges of the middle area of ​​the load back plate 5. The two positioning posts 501 are respectively inserted into the two positioning holes 302 on the PCB board 3 to realize the positioning of the load back plate 5 on the PCB board 3. The insulating diaphragm 4 is provided with an avoidance hole for avoiding the positioning posts 501 of the load back plate 5. The positioning posts 501 have a simple structure and are easy to position. Of course, in addition to using positioning posts, the positioning structure can also be other structures. For example, in another embodiment, a convex bump is provided on the load back plate as a positioning structure, and when the load back plate is installed on the back of the PCB board, the convex bump is aligned with the positioning holes on the PCB board to achieve positioning.

[0023] The connector 1 includes a housing 101, an insulating body 104 installed in the housing 101, and a cable assembly 102 installed in the insulating body 104. The rear side of the housing 101 has an escape port for escaping the cables. Two mounting grooves 105 are provided in the insulating body 104. The front ends of the two cable assemblies 102 are respectively installed in the two mounting grooves 105, and the rear ends are outlet terminals. The cable assembly 102 includes a terminal module, a cable connected to the terminal module, and a shielding structure 103 arranged on one side of the terminal module. The shielding structure 103 is electrically conductive with the grounding terminal of the terminal module. The housing 101 and the shielding structures 103 of each cable assembly 102 are electrically conductive. A sealing insulator 107 for sealing each cable assembly 102 in the insulating body 104 is provided on the rear side of the insulating body 104. The housing 101 and the sealing insulator 107 are snap-connected. The insulating body 104 is provided with a positioning boss 106 protruding from the lower surface of the insulating body 104, and the positioning boss 106 is used to position and cooperate with the positioning hole 302 on the PCB board 3 to ensure the installation position of the connector 1 on the PCB board 3. The two positioning bosses 106 and the two positioning posts 501 on the load back plate 5 share the positioning hole 302 on the PCB board 3, and only one group of positioning holes 302 needs to be opened on the PCB board 3, which is conducive to simplifying the structure of the PCB board 3. Of course, in actual applications, the positioning bosses on the insulating body and the positioning posts on the load back plate can also be positioned and cooperated with different positioning holes on the PCB board respectively, and two groups of positioning holes can be opened on the PCB board.

[0024] The four corners of the load back plate 5 are provided with threaded holes 502, respectively. The locking screws 2 pass through the connector 1, the PCB board 3, and the insulating film 4 and are screwed into the threaded holes 502 on the load back plate 5. The housing 101 of the connector 1 and the load back plate 5 are electrically connected through the locking screws 2. At the same time, the housing 101 and the shielding structure 103 of each cable assembly 102 are electrically connected. The housing 101 and the load back plate 5 jointly form an outer shielding cover on the outside of each cable assembly 102, shielding the front end of each cable assembly 102 from five directions: top, bottom, left, right, and front. The rear side is the cable outlet direction, thereby avoiding electromagnetic crosstalk between the connector and other connectors in the application environment.

[0025] The connector assembly of the utility model provides an adhesive structure on the load back plate 5. When the connector 1 is installed on the surface of the PCB board 3, the load back plate 5 can be adhesively fixed to the back side of the PCB board 3 in advance, and then the connector 1 can be fixed to the surface of the PCB board 3. There is no need to consider the problem of pressing the load back plate 5, thereby solving the defect of inconvenient installation of the load back plate when the connector is installed on the surface of the PCB board, making the installation operation of the connector and the load back plate more convenient.
