[0001] The utility model relates to the technical field of electric connectors, in particular to an elastic grounding connector. Background Art

[0002] With the development of electronic equipment and electrical systems, the electromagnetic compatibility (EMC) requirements of equipment are getting higher and higher. Electromagnetic interference (EMI) and electromagnetic radiation (EMR) pose a serious threat to the normal operation of modern electronic equipment, especially in applications with high frequency and high-speed data transmission. In order to solve this problem, various shielding and grounding technologies are widely used to reduce electromagnetic interference and improve system reliability.

[0003] Traditional elastic grounding connectors are usually made of rigid materials such as copper or aluminum. Although such grounding connectors have excellent conductivity, they have some shortcomings in practical applications. For example, some elastic grounding connectors are prone to poor contact under mechanical vibration and impact conditions, thus affecting the grounding effect. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that poor contact of the connector is likely to occur under mechanical vibration and impact conditions, thereby affecting the grounding effect, and proposes an elastic grounding connector.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A resilient grounding connector comprises: a terminal, comprising a shell, a first male contact and a second male contact, wherein the first male contacts are arranged equidistantly in the shell, and the second male contacts are arranged on two sides of the shell relatively; a plug, wherein a female contact is installed inside, and when the plug is inserted into the terminal, the female contact contacts the first male contact and the second male contact; wherein a clamping unit is arranged on both sides of the shell, and when the female contacts at both ends of the plug are inserted into the clamping unit and abut against the second male contact, the clamping unit limits the position of the female contacts.

[0007] In order to prevent looseness and poor contact when the terminal and the plug are connected, preferably, the card connection unit includes: an elastic sheet fixedly installed in the shell, the elastic sheet having a window; a card block rotatably installed in the shell, the card block having symmetrically arranged extension ends, the extension ends away from the side of the plug passing through the window and abutting against the bottom surface of the window, an extrusion plate fixedly installed on the card block, for pressing the female contact against the second male contact; a socket for inserting the female contact.

[0008] In order to allow the device to adapt to tiny displacements and vibrations and be suitable for various complex working environments, further, the block has a connecting shaft, the housing has a sleeve for accommodating the connecting shaft, the connecting shaft is rotatably installed in the sleeve and a torsion spring is fixed between the inner wall of the sleeve.

[0009] In order to effectively reduce the friction and corrosion of the female contact on the first male contact, further, preferably, the first male contact includes a horizontal portion, the horizontal portion has an openable and closable clip, and the cross-section of the clip is a triangle in the original state.

[0010] In order to improve the integrity of the signal and effectively reduce the overheating phenomenon, further, the clips on the adjacent horizontal parts are arranged in a front-to-back staggered manner.

[0011] In order to effectively increase the contact area between the female contact and the second male contact, further, the second male contact is in a sheet-like structure and is fixedly mounted on one side of the jack.

[0012] Compared with the prior art, the utility model provides an elastic grounding connector, which has the following beneficial effects:

[0013] 1. The elastic grounding connector provides multi-point contact through the configuration of the first male contact and the second male contact, thereby enhancing the stability and reliability of the electrical connection. The card connection unit limits the position of the female contact to ensure that the first male contact and the second male contact will not loosen or shift during the connection process, thereby improving the mechanical strength of the overall connection. It also has certain elastic properties and can adapt to slight displacements and vibrations, reducing poor contact or looseness of the connector caused by external forces during use.

[0014] 2. In the design of the electrical connector, the elastic grounding connector has the front-to-back staggered arrangement of the clips to reduce the possibility of incorrect insertion. Since the position of each first male contact and female contact is specific, incorrect insertion becomes more difficult, which helps prevent connection errors and thus improves the safety of the system. At the same time, the front-to-back alternating arrangement ensures that each contact is subjected to uniform pressure when connected, thereby improving contact reliability. This design can reduce the contact resistance between the contacts, ensure the stability and consistency of the electrical connection, and the alternating arrangement of the male and female contacts helps to reduce electromagnetic interference. Since the male and female contacts are alternately arranged, the distribution of the electromagnetic field will be more uniform, thereby reducing the possibility of interference, improving the integrity of the signal, and effectively reducing overheating.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] Example:

[0023] Reference Figure 1-Figure 4 , an elastic grounding connector, including a terminal 1 and a plug 2.

[0024] Reference Figure 1 and Figure 4The terminal 1 includes a housing 11, which provides a solid structure for accommodating and protecting the internal components, a first male contact 12 and a second male contact 13, the first male contact 12 is arranged equidistantly in the housing 11, and the second male contact 13 is relatively arranged on both sides of the housing 11. The first male contacts 12 are arranged equidistantly in the housing 11 to ensure uniform distribution to achieve good electrical connection and mechanical stability, and the second male contacts 13 are relatively arranged on both sides of the housing 11, which increases the number of contacts and the contact area, thereby enhancing the reliability of the electrical connection. The female contact 21 is installed inside the plug 2, and when the plug 2 is plugged into the terminal 1, the female contact 21 contacts the first male contact 12 and the second male contact 13.

[0025] Specifically, the housing 11 is provided with snap-fit ​​units 14 on both sides. When the female contacts 21 at both ends of the plug 2 are inserted into the snap-fit ​​units 14 and abut against the second male contacts 13 , the snap-fit ​​units 14 limit the positions of the female contacts 21 .

[0026] The clamping units 14 on both sides of the housing 11 provide position limitation when the female contact 21 is inserted, ensuring that the female contact 21 is accurately docked with the second male contact 12, thereby improving the stability of the connection.

[0027] An elastic grounding connector of the present embodiment provides multi-point contact through the configuration of the first male contact 12 and the second male contact 13, thereby enhancing the stability and reliability of the electrical connection. The snap-in unit 14 limits the position of the female contact 21 to ensure that the first male contact 12 and the second male contact 13 will not loosen or shift during the connection process, thereby improving the mechanical strength of the overall connection. The connector has certain elastic properties and can adapt to slight displacements and vibrations, thereby reducing poor contact or looseness of the connector caused by external forces during use.

[0028] Each structure is described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 2 and Figure 3 The card connection unit 14 includes: an elastic sheet 141 fixedly installed in the housing 11, and the elastic sheet 141 has a window 142; a card block 143 rotatably installed in the housing 11, and the card block 143 has symmetrically arranged extension ends 144, and the extension ends 144 on the side away from the plug 2 pass through the window 142 and abut against the bottom surface of the window 142, and an extrusion plate 147 is fixedly installed on the card block 143 for pressing the female contact 21 against the second male contact 13; a socket 145 for inserting the female contact 21.

[0030] The block 143 has a connecting shaft 146 , and the housing 11 has a sleeve 111 for accommodating the connecting shaft 146 . The connecting shaft 146 is rotatably installed in the sleeve 111 and a torsion spring 148 is fixed between the connecting shaft 146 and the inner wall of the sleeve 111 .

[0031] Optionally, the second male contact 13 is in a sheet-like structure and is fixedly mounted on one side of the insertion hole 145 .

[0032] Through the setting of the above structure, the female contact 21 is inserted into the socket 145 to push the elastic sheet 141 to deform and loosen the position of the block 143. The block 143 rotates and resets under the action of the torsion spring 148. The extrusion plate 147 fixed on the block 143 presses the female contact 21 and the second male contact 13 tightly to prevent loosening and poor contact. When the connection needs to be disconnected, the block 143 can be pressed to squeeze the plate 147 to return to its original position under the action of the elastic sheet 141 and the torsion spring 148 to ensure that it can be accurately docked again when inserted next time. The design of the elastic sheet 141 and the torsion spring 148 allows the device to adapt to small displacements and vibrations, and is suitable for various complex working environments.

[0033] Reference Figure 4 The first male contact 12 includes a horizontal portion 121, and the horizontal portion 121 has an openable and closable clip 122, and the cross section of the clip 122 is triangular in the original state.

[0034] The clips 122 on adjacent horizontal portions 121 are arranged alternately front to back.

[0035] By setting the above structure, in the design of the electrical connector, the front-to-back staggered arrangement of the clips 122 can reduce the possibility of incorrect insertion. Since the positions of each first male contact 13 and the female contact 21 are specific, incorrect insertion becomes more difficult, which helps prevent connection errors and thus improves the safety of the system. At the same time, the front-to-back alternating arrangement can ensure that each contact is subjected to uniform pressure when connected, thereby improving contact reliability. This design can reduce the contact resistance between contacts, ensure the stability and consistency of the electrical connection, and the alternating arrangement of the female contacts 21 helps to reduce electromagnetic interference; since the female contacts 21 are arranged alternately, the distribution of the electromagnetic field will be more uniform, thereby reducing the possibility of interference, improving the integrity of the signal, and effectively reducing overheating.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
