[0036] The connector and electrical device provided above provide at least two stoppers on the main body along the vibration direction of the external connector to reduce the vibration range of the external connector when the external connector vibrates at a high frequency, thereby reducing the problem of poor contact at the connection between the external connector and the terminal assembly caused by long-term long-amplitude vibration of the external connector in a high-frequency vibration environment.

[0037] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] Embodiment 1

[0039] See also Figure 1-Figure 5 The present application provides a connector 100, comprising a connector 10 and at least two stoppers 20. The connector 10 comprises a body 11 and a terminal assembly 12, the body 11 is provided with a plug-in cavity 11a, the terminal assembly 12 is arranged in the plug-in cavity 11a, and an external connector 200 can be plugged into the plug-in cavity 11a and snap-fit ​​with the terminal assembly 12. Along the vibration direction of the external connector 200, at least two stoppers 20 are respectively arranged on two opposite sides of the body 11, for stopping and reducing the vibration range of the external connector 200.

[0040] The connector 100 and the electrical device provided above are provided with at least two stoppers 20 on the main body 11 along the vibration direction of the external connector 200, so as to reduce the vibration range of the external connector 200 when the external connector 200 vibrates at a high frequency, thereby reducing the problem of poor contact at the connection between the external connector 200 and the terminal assembly 12 caused by the long-term long-amplitude vibration of the external connector 200 in a high-frequency vibration environment.

[0041] It should be noted that when the above connector 100 is applied to high mechanical strength, high temperature and high pressure and high frequency electromagnetic environment, the external connector 200, such as busbars, etc., will vibrate with the terminal assembly 12 of the connector 100 due to the physical pressure and stress between them or the material expansion caused by the high temperature environment or the rapid change of the current in the connector 100 caused by the high frequency electromagnetic wave to generate electromagnetic force, and the connection between the external connector 200 and the terminal assembly 12 is not tight and becomes loose, thereby causing poor contact. The above scheme sets at least two stoppers 20 to stop the amplitude of the external connector 200 during high frequency vibration, so as to reduce the problem of poor contact between the external connector 200 and the terminal assembly 12 due to long-term high amplitude vibration.

[0042] In a specific embodiment, the connector 100 is an electrical connector 100 , and the external device connector 200 is a bus bar or a bus bar.

[0043] In a specific embodiment, the stopper 20 is substantially a cylindrical structure.

[0044] See also Figure 2 , Figure 3 and Figure 5 In order to facilitate the setting of the stopper 20 to better limit the vibration amplitude of the external connector 200, in a specific embodiment, the main body 11 includes a first stopper 111 and a plug-in portion 112 arranged in sequence along its length direction, and at least two of the stoppers 20 are respectively arranged on two opposite sides of the first stopper 111; the terminal assembly 12 is arranged on the plug-in portion 112 for clamping the external connector 200.

[0045] It should be noted that by arranging at least two stop members 20 on two opposite sides of the first stop portion 111, when the external connector 200 vibrates at a high frequency, at least two stop members 20 can stop the external connector 200 from both the upper and lower directions at the same time, so as to ensure the swing amplitude of the external connector 200 in the upper and lower vibrations, thereby avoiding the problem of local poor contact caused by excessive swing amplitude in a single direction, and better ensuring the stability of the connection between the external connector 200 and the terminal assembly 12.

[0046] Furthermore, in order to facilitate better arrangement of the terminal assembly 12 in the main body 11, in a specific embodiment, along the vibration direction of the external connector 200, two opposite sides of the plug-in portion 112 are provided with accommodating openings 112a; the terminal assembly 12 includes a first terminal 121 and a second terminal 122, and the first terminal 121 and the second terminal 122 are elastically arranged in the accommodating openings 112a on the opposite sides of the plug-in portion 112, respectively.

[0047] It should be noted that one end of the first terminal 121 and the second terminal 122 are respectively fixed on the side wall of the receiving opening 112a, and the other end extends into the plug-in cavity 11a, so as to resist the external plug-in component 200, and when the external plug-in component 200 is pulled out, the first terminal 121 and the second terminal 122 are reset due to their elasticity, so as to facilitate multiple plug-ins and pull-outs. The above scheme avoids the problem that the first terminal 121 and the second terminal 122 are located in the receiving opening 112a on two opposite surfaces of the plug-in portion 112, thereby avoiding the problem that the first terminal 121 and the second terminal 122 are located in the plug-in cavity 11a and occupy an area, resulting in the connector 100 being too large in size.

[0048] In a specific embodiment, the first terminal 121 and the second terminal 122 are highly elastic copper sheets.

[0049] Furthermore, in order to facilitate the clamping of the terminal assembly 12 on the external connector 200, in a specific embodiment, the first terminal 121 has a first contact 121a, and the second terminal 122 has a second contact 122a; along the vibration direction of the external connector 200, the distance from the first contact 121a to the second contact 122a is less than the distance between the two opposite stoppers 20.

[0050] In a specific embodiment, the first contact 121a is a point where the first terminal 121 contacts and conducts electricity with the external device connector 200, and the second contact 122a is a point where the second terminal 122 contacts and conducts electricity with the external device connector 200. The above scheme makes the distance from the first contact 121a to the second contact 122a smaller than the distance between the two stoppers 20, so that when the external device connector 200 is inserted into the plug-in cavity 11a, the external device connector 200 can be clamped on the first contact 121a of the first terminal 121 and the second contact 122a of the second terminal 122, and at this time, the external device connector 200 will not interfere with the stopper 20, that is, the smooth insertion of the external device connector 200 can be ensured, and the vibration amplitude of the external device connector 200 can be well limited.

[0051] Furthermore, in order to better limit the amplitude of the external device connector 200, in a specific embodiment, the main body 11 also includes a second stop portion 113, and the second stop portion 113 is arranged on the connector 112 along the length direction of the main body 11; there are multiple stop members 20, and along the vibration direction of the external device connector 200, multiple stop members 20 are arranged on two opposite sides of the second stop portion 113.

[0052] The above scheme is achieved by respectively arranging a plurality of stop members 20 at the first stop portion 111 and the second stop portion 113, that is, by respectively arranging the stop members 20 next to the openings at opposite ends of the main body 11, so that when the external connector 200 is inserted through the plug-in cavity 11a and vibrates at a high frequency, the stop members 20 located at the openings at both ends of the main body 11 can simultaneously stop the vibration of the external connector 200, thereby better limiting the high-frequency vibration of the external connector 200.

[0053] In a specific embodiment, there are eight stoppers 20 disposed on the first stopper portion 111 and the second stopper portion 113 .

[0054] In order to facilitate the connector 100 to simultaneously connect to the electrical device where the external plug-in component 200 is located and another electrical device to form an electrical connection, in a specific embodiment, the main body 11 also includes an electrical connection portion 114; the electrical connection portion 114 is arranged at one end of the first stop portion 111 away from the plug-in portion 112, and the electrical connection portion 114 can connect the external electrical device with the terminal assembly 12.

[0055] In a specific embodiment, when the connector 100 is used, one end of the external device connector 200 is electrically connected to the electrical device, and the other end is inserted into the plug cavity 11a and engaged with the first terminal 121 and the second terminal 122. At this time, the electrical connection portion 114 is attached to the electrical connection end of another electrical device, so that the two electrical devices are connected to each other, thereby playing the role of the connector 100.

[0056] In order to ensure the stability of the electrical connection between the electrical connection part 114 and the electrical device, in a specific embodiment, there are two electrical connection parts 114 , and the two electrical connection parts 114 are symmetrically arranged at one end of the first stop part 111 away from the plug-in part 112 .

[0057] The above scheme arranges two symmetrical point connection parts at one end of the first stop part 111 away from the plug-in part 112 so as to fit the electrical connection end of the electrical equipment at the same time, and the two symmetrical electrical connection parts 114 can form a force balance when the main body 11 is connected to the electrical equipment, thereby avoiding the problem of unstable connection caused by uneven force.

[0058] In a specific embodiment, the electrical connection portion 114 is a copper sheet or the like.

[0059] For ease of manufacturing, in a specific embodiment, the electrical connection portion 114, the first stop portion 111, the plug portion 112 and the terminal assembly 12 are made of conductive metal and are integrally formed. Preferably, the electrical connection portion 114, the first stop portion 111, the plug portion 112 and the terminal assembly 12 are formed by pressing and then winding copper sheets.

[0060] In order to further suppress the high-frequency vibration of the connector 100 , the connector 100 further includes a shockproof shell 30 . The shockproof shell 30 is sleeved on the outer wall of the body 11 to suppress the vibration of the body 11 .

[0061] In the above scheme, when the electrical connection part 114 or the electrical equipment connected to the external connector 200 has high-frequency vibration and drives the main body 11 to vibrate, the inner wall of the shockproof shell 30 can stop the vibration of the main body 11, i.e., the external connector 200, thereby avoiding the vibration amplitude of the external connector 200 and the main body 11, thereby further reducing the vibration amplitude between the external connector 200 and the main body 11, thereby enhancing the stability of the device connection.

[0062] The connector 100 and the electrical device provided above are provided with at least two stoppers 20 on the main body 11 along the vibration direction of the external connector 200, so as to reduce the vibration range of the external connector 200 when the external connector 200 vibrates at a high frequency, thereby reducing the problem of poor contact at the connection between the external connector 200 and the terminal assembly 12 caused by the long-term long-amplitude vibration of the external connector 200 in a high-frequency vibration environment.

[0063] Embodiment 2

[0065] It should be noted that the above-mentioned electrical devices may be all electrical equipment that requires the use of the connector 100 .

[0066] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
