Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, and more specifically to an electromagnetic interference resistant connector. Background Art

[0002] Connectors are essential basic components in electrical and electronic equipment, and play a vital role in the transmission and control of energy and signals in electronic systems. For example, a rectangular connector anti-electromagnetic interference and electromagnetic compatibility mixed filter structure disclosed in the prior art includes an upper shell and a lower shell, and a filter contact assembly and a power pin arranged between the upper shell and the lower shell. The filter contact assembly includes a pin contact, a filter inductor and a filter capacitor, and the filter inductor and the filter capacitor are welded on the pin contact.

[0003] In the above-mentioned prior art, the connector is generally also connected to a shielded cable. A shielding layer is arranged on the outside of the shielded cable. The shielding layer is overlapped with the metal shell of the connector to guide the external electromagnetic interference to the ground, thereby preventing interference with the electronic equipment or signals inside the signal transmission line, helping to improve electromagnetic compatibility (EMC) and ensure the normal operation of the equipment in the electromagnetic environment.

[0004] In order to prevent electromagnetic leakage, the shielding layer of the shielded cable needs to form a 360° closed overlap with the metal shell of the electrical connector. The commonly used overlap method is to clamp the shielded cable between the ends of the upper shell and the lower shell, so that the end of the shielding layer of the shielded cable is in contact with the inner wall of the metal shell.

[0005] However, during the use of the connector, the shielded cable is easily deformed or bent by external forces, and the shielded cable is easily loosened, causing the shielding layer of the shielded cable to separate from the metal shell, ultimately leading to increased electromagnetic interference and a decrease in the quality and integrity of the transmitted signal. Utility Model Content

[0006] In view of the problem in the above-mentioned prior art that the shielded cable is easily loosened or even detached from the connector housing, resulting in increased electromagnetic interference of the connector, the utility model provides an electromagnetic interference-resistant connector, which can improve the connection firmness between the shielded cable and the connector housing and improve the anti-electromagnetic interference capability of the connector.

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0008] An electromagnetic interference resistant connector comprises a shell provided with a protective cavity and an electrical component arranged in the protective cavity and connected to the shell, the outside of the shell is connected to a tail clip component, the tail clip component is provided with a through cavity for passing a shielded cable, the through cavity extends from one end of the tail clip component to the surface of the shell, an elastic member is provided in the through cavity, one end of the elastic member is connected to the inner wall of the through cavity, and the other end is used to abut against the shielding layer of the shielded cable.

[0009] In the above technical solution, one end of the shielded cable can be inserted into the through cavity until it is completely in contact with the outer surface of the shell, and the elastic member abuts against the shielding layer of the shielded cable. When the shielded cable is subjected to external force, the elastic member can maintain abutment with the shielding layer of the shielded cable through its own elastic deformation, which can prevent the shielded cable from being separated from the shell surface of the connector due to vibration, movement or other external forces, thereby improving the connection firmness between the shielded cable and the shell, thereby improving the anti-electromagnetic interference performance of the connector.

[0010] The elastic member may be a spring, a leaf spring or an elastic material block.

[0011] Preferably, the elastic member is a spring. The spring can provide a high mechanical fixing force to ensure that the shielded cable can be firmly fixed on the through cavity.

In addition, the spring can effectively connect the shielding layer of the shielded cable with the tail clip assembly, further improving the electromagnetic shielding effect.

[0012] Preferably, the spring sheet is provided with a plurality of pieces and at least partially distributed along the circumferential direction, which can further improve the fixing effect of the spring sheet on the shielded cable and make the connection between the shielded cable and the housing more stable.

The detachable connection between the left clamp and the right clamp is conducive to quickly fixing the shielded cable on the through cavity, thereby improving the assembly efficiency of the shielded cable and the connector, and also conveniently removing the shielded cable for inspection and maintenance. The first pressure protrusion and the second pressure protrusion can clamp the shielded cable, further improving the connection firmness between the shielded cable and the connector shell, and because the shielded cable is supported by the elastic member, the first pressure protrusion and the second pressure protrusion at the same time, the bending loss of the shielded cable can be reduced.

[0014] The left clamp and the right clamp may be connected to the housing by snap-fitting, threading or connecting with a connector, and the left clamp assembly may be connected to the right clamp assembly by snap-fitting, threading or connecting with a connector.

Such a connection structure is relatively simple and can provide a higher connection strength, so that the tail clip assembly is not easy to shake or fall off, thereby making the connection between the shielded cable and the shell more firm and reliable. At the same time, the conical connection structure can provide better connection sealing and can better protect the shielded cable from the influence of the external environment.

[0016] Preferably, the housing includes a left housing and a right housing, the left housing is detachably connected to the right housing, and the inner cavity of the left housing and the inner cavity of the right housing form the protective cavity, and the tail clip assembly is connected to the left housing or the right housing.

[0019] Preferably, the electrical component includes a grounding structure, an upper connection seat and a lower connection seat, the grounding structure is connected to the housing; the upper connection seat is provided with a plurality of first pins, the lower connection seat is provided with a plurality of second pins connected to the first pins in a one-to-one correspondence, an inductor is provided between the first pins and the second pins, and the first pins and the second pins are respectively connected to the grounding structure. It can be understood that when in use, the current is input from the first pin and output through the second pin.

In addition, such a setting can provide additional filtering effects, absorb the energy of high-frequency noise or transient overvoltage, make the voltage in the circuit more stable, and enable the connector to have better surge protection function.

[0021] Preferably, a second capacitor is provided on the lower connection base, and the two ends of the second capacitor are connected to the second pin and the grounding structure respectively.

[0038] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0039] Example 1

[0040] Combination Figures 1 to 5 An electromagnetic interference-resistant connector is shown, which includes a shell 1 provided with a protective cavity 101 and an electrical component arranged in the protective cavity 101 and connected to the shell 1. The outside of the shell 1 is connected to a tail clip assembly 2, and the tail clip assembly 2 is provided with a through cavity 203 for passing a shielded cable. The through cavity 203 extends from one end of the tail clip assembly 2 to the surface of the shell 1. An elastic member 3 is provided in the through cavity 203, one end of the elastic member 3 is connected to the inner wall of the through cavity 203, and the other end is used to abut against the shielding layer of the shielded cable.

[0041] Specifically, the housing 1 includes a left housing 102 and a right housing 103, the left housing 102 and the right housing 103 are detachably connected, and the inner cavity of the left housing 102 and the inner cavity of the right housing 103 form a protective cavity 101; the tail clip assembly 2 is connected to the right housing 103. Providing the housing 1 with detachable left housing 102 and right housing 103 can facilitate the maintenance of electrical components and the replacement of some components.

[0042] Specifically, the tail clamp assembly 2 includes a left clamping member 201 and a right clamping member 202, both of which are detachably connected to the right housing 103. The left clamping member 201 and the right clamping member 202 are detachably connected and a through cavity 203 is formed between the two. A first pressure protrusion 2011 is provided on the side of the left clamping member 201 away from the housing 1, and a second pressure protrusion 2021 is provided on the side of the right clamping member 202 away from the housing 1. The first pressure protrusion 2011 and the second pressure protrusion 2021 are both located on the inner wall of the through cavity 203, and an elliptical cavity structure is formed between the first pressure protrusion 2011 and the second pressure protrusion 2021. The detachable connection between the left clamping member 201 and the right clamping member 202 is conducive to quickly fixing the shielded cable on the through cavity 203, thereby improving the assembly efficiency of the shielded cable and the connector, and also conveniently removing the shielded cable for inspection and maintenance. The first pressure protrusion 2011 and the second pressure protrusion 2021 can clamp the shielded cable, further improving the connection firmness between the shielded cable and the connector housing 1. In addition, since the shielded cable is supported by the elastic member 3, the first pressure protrusion 2011 and the second pressure protrusion 2021 at the same time, the bending loss of the shielded cable can be reduced.

[0043] Specifically, the left clamping member 201 and the right clamping member 202 are connected by screws (not shown in the figure). Specifically, a first screw hole is respectively provided on the upper and lower sides of the left clamping member 201, and a second screw hole 2022 is respectively provided on the upper and lower sides of the right clamping member 202. The positions of the first screw holes and the second screw holes 2022 correspond to each other, one of the first screw holes and the second screw hole 2022 is connected by one screw, and another first screw hole and another second screw hole 2022 are connected by one screw.

[0044] Furthermore, a conical protrusion 104 is provided on the right shell 103, and an external thread is provided on the conical surface of the conical protrusion 104; a flared portion 2031 is provided on the side of the through cavity 203 close to the shell 1, and an internal thread is provided on the inner wall of the flared portion 2031, and the external thread is connected to the internal thread. In other words, the connection between the tail clip assembly 2 and the shell 1 is a threaded connection. Such a connection structure is relatively simple and can provide a higher connection strength, so that the tail clip assembly 2 is not easy to shake or fall off, thereby making the connection between the shielded cable and the shell 1 more firm and reliable. At the same time, the conical connection structure can provide better connection sealing, which can better protect the shielded cable from the influence of the external environment.

[0045] Specifically, the elastic member 3 is a spring leaf. The spring leaf can provide a high mechanical fixing force to ensure that the shielded cable can be firmly fixed on the through cavity 203. The structure of the spring leaf is relatively simple, and the installation and replacement are relatively simple. In addition, the spring leaf can effectively connect the shielding layer of the shielded cable with the tail clip assembly 2, further improving the electromagnetic shielding effect.

[0046] Furthermore, the spring sheets are provided in multiple pieces and some are distributed along the circumferential direction and some are distributed along the axial direction of the through cavity 203 , which can further improve the fixing effect of the spring sheets on the shielded cable and make the connection between the shielded cable and the housing 1 more stable.

[0047] The working principle or workflow of this embodiment: During implementation, one end of the shielded cable 14 passes through the through cavity 203 until it is completely in contact with the surface of the conical protrusion 104, and at the same time, the first pressure protrusion 2011 and the second pressure protrusion 2021 respectively abut against the shielding layer of the shielded cable 14, and the elastic member 3 abuts against the shielding layer of the shielded cable 14. When the shielded cable 14 is subjected to external force, the elastic member 3 can maintain abutment with the shielding layer of the shielded cable through its own elastic deformation, which can prevent the shielded cable from being separated from the surface of the conical protrusion 104 of the connector due to vibration, movement or other external forces, and the first pressure protrusion 2011 and the second pressure protrusion 2021 simultaneously press the shielded cable 14, which can improve the connection firmness between the shielded cable 14 and the housing 1, thereby improving the anti-electromagnetic interference performance of the connector.

[0049] (1) A tail clip assembly is provided on the housing, and an elastic member is provided in the tail clip assembly to compress the shielded cable, thereby preventing the shielded cable from being separated from the housing surface of the connector due to vibration, movement or other external forces, maintaining the stability and reliability of the connection between the shielded cable and the housing, thereby improving the anti-electromagnetic interference performance of the connector.

[0050] (2) The tail clamp assembly includes a left clamp and a right clamp that are detachably connected, which is conducive to quickly fixing the shielded cable on the through cavity, and the left clamp and the right clamp are respectively provided with a first pressure protrusion and a second pressure protrusion, which can further improve the connection firmness between the shielded cable and the connector housing and reduce the bending loss of the shielded cable.
