Description

Technical Field

[0001] This application relates to the field of shielding shell grounding technology, and in particular to a connector shielding shell grounding plate structure. Background Technology

[0002] Today, in fields such as electronic communications, industrial control, and automotive electronics, connectors serve as core interface components for signal and power transmission, and their electromagnetic compatibility (EMC) performance directly affects the operational stability of the entire system. MCC coaxial cables, due to their low loss and anti-interference characteristics, are widely used in high-frequency signal transmission scenarios. The mating structure of the connector shield and grounding plate is a crucial element in achieving EMC grounding and suppressing interference signals.

[0003] In existing technologies, traditional connector shielding shell grounding plate structures mostly adopt an embedded design, with the grounding contact and the soldering area of ​​the connector shell hidden in the insertion slot inside the shell, or obstructed by the wire core and shell structure. This layout results in a small soldering operation space and obstructed vision, making it difficult for operators to accurately control the amount of solder and the soldering force. On the one hand, it is easy to make the soldering operation cumbersome and time-consuming, affecting production efficiency, and it is also easy to cause grounding problems due to insufficient solder, affecting EMC performance. On the other hand, excessive force or operational deviation can easily break the fragile wire core or grounding plate contact, causing component scrap and increasing production loss rate.

[0004] Therefore, we propose a connector shielding shell grounding plate structure to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a connector shielding shell grounding plate structure that improves the assembly efficiency of the MCC coaxial cable, grounding plate, and connector shell. By designing the grounding plate to extend to the outside of the connector shell, it is easier to solder to the connector shell, providing a wide operating space and clear aiming point for soldering operations. Operators can accurately control the soldering process, effectively avoiding the risk of the grounding plate or wire core being crushed due to operation restrictions. At the same time, it ensures that the solder joint is full and firm, fundamentally improving the reliability of EMC grounding, simplifying the soldering steps, reducing the rework rate, thereby solving the risk of connector soldering being crushed, and improving production efficiency.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a connector shielding shell grounding plate structure, including an MCC coaxial line, a grounding plate and a connector shell, wherein multiple wire cores are fixedly connected inside the MCC coaxial line, one end of each of the multiple wire cores extends outside the MCC coaxial line and is evenly distributed in a row, and a plug-in groove is opened on the front side of the connector shell, one end of each of the multiple wire cores is plugged into the plug-in groove, the grounding plate is disposed on the upper surface of the multiple wire cores and located in the plug-in groove, the grounding plate includes a grounding plate body and a grounding plate protrusion, the multiple wire cores are in contact with the lower surface of the grounding plate body, the grounding plate protrusion is fixedly connected to the front side wall of the grounding plate body, and one end of the grounding plate protrusion away from the grounding plate body extends outside the connector shell.

[0007] A further feature of this application is that the grounding plate also includes multiple positioning strips, which are all fixedly connected to the bottom surface of the grounding plate body and arranged at equal intervals, with the wire core located between two adjacent positioning strips.

[0008] A further feature of this application is that the grounding plate body is a rectangular strip.

[0009] A further feature of this application is that the grounding plate protrusion is integrally cast with the grounding plate body, and the positioning strip is integrally cast with the grounding plate body.

[0010] A further feature of this application is that the outer surfaces of both the grounding plate body and the grounding plate protrusion are smooth planar structures, and the upper surface of the grounding plate body is in contact with the top inner wall of the insertion slot.

[0011] A further feature of this application is that the grounding plate body, the grounding plate protrusion, and the positioning strip are all made of copper, and the connector housing is made of stainless steel.

[0012] A further feature of this application is that the top of the connector housing has a plurality of uniformly distributed through holes, all of which are connected to the insertion slot.

[0013] This application includes at least one of the following beneficial technical effects:

[0014] 1. This application utilizes a grounding plate composed of a grounding plate body, a grounding plate protrusion, and a positioning strip. By designing the grounding plate protrusion to extend to the outside of the connector housing, it is easier to solder to the connector housing. This provides a wide operating space and a clear aiming point for soldering operations, allowing operators to precisely control the soldering process. This effectively avoids the risk of the grounding plate or wire core being crushed due to limited operation, while ensuring a full and firm solder joint. This fundamentally improves the reliability of EMC grounding, simplifies the soldering steps, reduces the rework rate, and thus solves the risk of connector soldering being crushed, while also improving production efficiency.

[0015] 2. This application utilizes the space between multiple positioning strips to quickly limit and arrange the cores of the MCC coaxial cable, eliminating the need for manual alignment of each core. This significantly shortens the assembly time between the grounding plate and the cores inside the MCC coaxial cable, further improving production efficiency. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] See Figures 1-6This application provides a connector shielding shell grounding plate structure, including an MCC coaxial line 1, a grounding plate 2, and a connector shell 3. Multiple wire cores 101 are fixedly connected inside the MCC coaxial line 1, with one end of each core extending outside the MCC coaxial line 1 and evenly distributed in a row. A insertion slot 301 is provided on the front side of the connector shell 3, and one end of each core 101 is inserted into the insertion slot 301. The grounding plate 2 is disposed on the upper surface of the multiple cores 101 and located within the insertion slot 301. The grounding plate 2 includes a grounding plate body 201 and a grounding plate protrusion 202. The multiple cores 101 are in contact with the lower surface of the grounding plate body 201, forming a unified grounding loop, which can quickly discharge interference current generated during the transmission of the cores 101. The grounding plate protrusion 202 is fixedly connected to the front sidewall of the grounding plate body 201. The end of the grounding plate protrusion 202 away from the grounding plate body 201 extends to the outside of the connector housing 3. After the MCC coaxial cable 1, grounding plate 2 and connector housing 3 are assembled, the grounding plate protrusion 202 of the grounding plate 2 can be soldered to the connector housing 3 to achieve EMC function. The design of the grounding plate protrusion 202 extending to the outside of the connector housing 3 makes it easier to solder to the connector housing 3, providing a wide operating space and a clear aiming point for the soldering operation. The operator can accurately control the soldering process, effectively avoiding the risk of the grounding plate 2 or the wire core 101 being crushed due to operation restrictions. At the same time, it ensures that the solder joint is full and firm, fundamentally improving the reliability of EMC grounding, simplifying the soldering steps, reducing the rework rate, thereby solving the risk of connector soldering being crushed, and improving production efficiency.

[0025] In this embodiment, the grounding plate 2 also includes multiple positioning strips 203. The multiple positioning strips 203 are all fixedly connected to the bottom surface of the grounding plate body 201 and are arranged at equal intervals. The wire core 101 is located between two adjacent positioning strips 203. By utilizing the space formed by the multiple positioning strips 203, the wire core 101 of the MCC coaxial line can be quickly positioned and arranged without the need for manual alignment of the wire core 101 one by one. This greatly shortens the assembly time of the grounding plate 2 and the wire core 101 in the MCC coaxial line 1 and further improves the production efficiency.

[0026] In this embodiment, the grounding plate body 201 is rectangular strip-shaped. The outer surfaces of the grounding plate body 201 and the grounding plate protrusion 202 are both smooth flat structures. The upper surface of the grounding plate body 201 is in contact with the top inner wall of the insertion groove 301. By designing the grounding plate body 201 with a rectangular strip structure, its top is in close contact with the top inner wall of the insertion groove 301, and its bottom is in a limiting fit with the wire core 101 through the positioning strip 203. This allows the grounding plate 2 to achieve a stable state of being in close contact with the wire core 101 in the insertion groove 301, avoiding the problem of the grounding plate 2 shifting or the wire core 101 loosening due to vibration or external impact after assembly.

[0027] In this embodiment, the grounding plate protrusion 202 and the grounding plate body 201 are integrally cast, and the positioning strip 203 and the grounding plate body 201 are integrally cast. The grounding plate body 201, the grounding plate protrusion 202 and the positioning strip 203 adopt an integral casting process, which eliminates the need for subsequent assembly of multiple scattered parts, reduces processing steps and assembly errors, and reduces the complexity of the production process.

[0028] In this embodiment, the grounding plate body 201, the grounding plate protrusion 202 and the positioning strip 203 are all made of copper, and the connector housing 3 is made of stainless steel. By using the copper grounding plate 2 and the stainless steel connector housing 3 to form a compatible assembly, the stable conduction of the grounding circuit can be guaranteed, and the potential for component deformation during long-term use can be reduced.

[0029] In this embodiment, the top of the connector housing 3 is provided with a plurality of uniformly distributed through holes 302, all of which are connected to the insertion slot 301. The design of the plurality of through holes 302 can not only balance the air pressure inside and outside the insertion slot 301 and avoid the problem of loose fit caused by air blockage during assembly, but also help to dissipate the electromagnetic interference gathered around the wire core 101 inside the insertion slot 301. With reliable welding grounding, a double protection of internal shielding and external grounding is formed, which effectively improves the connector's anti-interference ability and signal transmission stability.

[0030] With the above structure, when the connector shielding shell grounding plate structure provided in this application is used, the operator places the grounding plate 2 on the upper surface of multiple wire cores 101, and makes multiple equally spaced positioning strips 203 at the bottom of the grounding plate body 201 sequentially lock between adjacent wire cores 101, realizing the automatic positioning and arrangement of wire cores 101. Then, the wire cores 101 and the grounding plate 2 are aligned with the insertion slot 301 on the front side of the connector shell 3, so that one end of the wire core 101 and the grounding plate 2 are inserted into the insertion slot 301, completing the initial positioning of the signal transmission carrier. At this time, the upper surface of the grounding plate body 201 is tightly attached to the top inner wall of the insertion slot 301, so that the grounding plate 2 forms a stable assembly state of upper and lower attachment in the insertion slot 301. The lower surface of the grounding plate body 201 is in full contact with multiple wire cores 101, and the grounding plate protrusion 202 of the grounding plate 2 is exposed outside the connector shell 3.

[0031] After the above assembly is completed, the operator will solder the grounding plate protrusion 202 that extends to the outside of the housing to form a firm electrical connection between the grounding plate 2 and the stainless steel connector housing 3, thus completing the grounding assembly operation.

[0032] During use, the lower surface of the grounding plate body 201 makes full contact with multiple wire cores 101. The interference current generated by the wire cores 101 during signal transmission will be quickly gathered through the copper metal grounding plate 2 to form a unified interference current conduction path, avoiding disorderly diffusion of interference current in the plug slot 301. The interference current gathered by the grounding plate 2 is conducted to the connector housing 3 through the grounding plate protrusion 202, and then introduced into the external grounding system from the housing, ultimately achieving effective release of interference current and achieving the core purpose of EMC grounding.
