A power connector and a connector assembly

Abstract

The present application provides a power connector and a connector assembly, including a shell and a bus bar and a connector respectively inserted at both ends of the shell, wherein the connector includes a body and a plurality of first terminals and a plurality of second terminals arranged at the plug-in end of the body; each of the first terminals has a first contact capable of contacting the bus bar, and each of the second terminals has a second contact capable of contacting the bus bar, and in the plug-in direction of the plug-in end, the first contact is located behind the second contact. In the power connector and connector assembly provided above, since the first contact of the connector is arranged behind the second contact, when the connector is inserted, the connector first contacts and squeezes the first contact that is relatively forward, and then gradually contacts the second contact that is relatively backward. This gradually increasing contact sequence effectively disperses the force during insertion, thereby avoiding the simultaneous force on the connector, thereby reducing the risk of connector breakage and the feeling of discomfort during plug-in and unplug operations.

Description

Technical Field

[0001] The present application relates to the field of electrical equipment, and in particular to a power connector and a connector assembly. Background Art

[0002] Power connectors are widely used in applications such as battery connectors, board-to-board connectors, and signal transmission. The demand for miniaturization and high-density connections in modern electronic devices has driven the continuous innovation and development of flexible pin technology, especially in consumer electronics and communication equipment.

[0003] Existing power connectors usually include a combination of a pin header and a female header. The pins on the pin header are all bent with the same height and length, so that when inserted into the female header, inward elastic pressure is generated to improve the reliability of the connection. Compared with traditional socket connectors, this design can achieve easier plugging and unplugging functions.

[0004] However, the pins on the existing connector pin header are bent at the same position. During the insertion process of the female header, the female header will squeeze the pins. Since all the pins are at the same position, all the pins will be subjected to the pressure of the female header at the same time when the pins are inserted. As a result, when the connector is inserted into the female header, the insertion resistance will increase instantly, resulting in difficulty in plugging. Utility Model Content

[0005] In view of this, it is necessary to provide a power connector that does not have excessive instantaneous resistance during the plugging and unplugging process, resulting in plugging difficulties, so as to solve the above problems.

[0006] An embodiment of the present application provides a power connector, comprising a housing and a bus bar and a connector respectively plugged into two ends of the housing, wherein the connector comprises a body and a plurality of first terminals and a plurality of second terminals provided at a plug-in end of the body;

[0007] Each of the first terminals has a first contact capable of contacting the bus bar, and each of the second terminals has a second contact capable of contacting the bus bar. In the plugging direction of the plugging end, the first contact is located behind the second contact.

[0008] In at least one embodiment of the present application, the second terminal further includes a contact portion, and the contact portion is provided on the second contact;

[0009] When viewed in the vertical direction, the width of the contact portion is smaller than the width of the second terminal.

[0010] In at least one embodiment of the present application, a plurality of the first terminals and a plurality of the second terminals are arranged at intervals on the body.

[0011] In at least one embodiment of the present application, the body includes a first portion and a second portion that fit together, and the plug-in ends of the first portion and the second portion are each provided with a plurality of first terminals and a plurality of second terminals.

[0012] In at least one embodiment of the present application, the body further includes a first fixing portion and a second fixing portion;

[0013] The first fixing portion is disposed on the first portion, and the second fixing portion is disposed on the second portion;

[0014] The first fixing portion and the second fixing portion are located on two side surfaces of the body close to the terminal, and are used to limit the opening and closing size between the terminals of the first portion and the second portion.

[0015] In at least one embodiment of the present application, the bus bar has a contact surface for contacting the first contact and the second contact, and the housing has a first surface and a second surface that are oppositely disposed and parallel to the contact surface;

[0016] The housing further comprises a first extension portion and a second extension portion, wherein the first extension portion is disposed on the first surface, and the second extension portion is disposed on the second surface;

[0017] The first extension portion and the second extension portion are used to be fixed on an electrical device.

[0018] In at least one embodiment of the present application, the power connector includes two fixing members;

[0019] The first extension portion is provided with a first fixing hole, and a fixing member is arranged in the first fixing hole for fixing the first extension portion to the electrical equipment;

[0020] The second extension portion is provided with a second fixing hole, and another fixing member is arranged in the second fixing hole for fixing the second extension portion to the electrical equipment;

[0021] Wherein, when the two fixing members are respectively arranged in the first fixing hole and the second fixing hole and fixed to the electrical equipment, a floating gap is formed between each of the fixing members and the first fixing hole and the second fixing hole.

[0022] In at least one embodiment of the present application, the fixing member is one of a screw or a steel sleeve.

[0023] In at least one embodiment of the present application, the first extending portion is perpendicular to the first surface, and the second extending portion is perpendicular to the second surface.

[0024] A connector assembly comprises a power connector as described in any one of the above.

[0025] In the power connector and connector assembly provided above, since the first contact of the connector is arranged behind the second contact, when the connector is inserted, the connector first contacts and squeezes the first contact in front, and then gradually contacts the second contact in the back. This gradually increasing contact sequence effectively disperses the force during insertion, thereby avoiding the connectors being stressed at the same time. The segmented force design makes the insertion process smoother, and the pressure on each connector is more uniform and dispersed, reducing the impact of instantaneous resistance on the connector and the female connector, thereby reducing the risk of connector breakage and the discomfort during plugging and unplugging operations.

[0037] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0038] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0039] An embodiment of the present application provides a power connector, comprising a housing and a bus bar and a connector respectively inserted at two ends of the housing, wherein the connector comprises a body and a plurality of first terminals and a plurality of second terminals arranged at a plug-in end of the body;

[0040] Each of the first terminals has a first contact capable of contacting the bus bar, and each of the second terminals has a second contact capable of contacting the bus bar. In the plugging direction of the plugging end, the first contact is located behind the second contact.

[0041] In the power connector and connector assembly provided above, since the first contact of the connector is arranged behind the second contact, when the connector is inserted, the connector first contacts and squeezes the first contact in front, and then gradually contacts the second contact in the back. This gradually increasing contact sequence effectively disperses the force during insertion, thereby avoiding the connectors being stressed at the same time. The segmented force design makes the insertion process smoother, and the pressure on each connector is more uniform and dispersed, reducing the impact of instantaneous resistance on the connector and the female connector, thereby reducing the risk of connector breakage and the discomfort during plugging and unplugging operations.

[0042] 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.

[0043] See also Figure 1-Figure 9 The embodiment of the present application provides a power connector 100, comprising a housing 10 and a bus bar 30 and a connector 20 respectively inserted at both ends of the housing 10, wherein the connector 20 comprises a body 21 and a plurality of first terminals 22 and a plurality of second terminals 23 arranged at the plug-in end of the body 21;

[0044] Each of the first terminals 22 has a first contact 221 capable of contacting the bus bar 30 , and each of the second terminals 23 has a second contact 231 capable of contacting the bus bar 30 . In the plugging direction of the plugging end, the first contact 221 is located behind the second contact 231 .

[0045] Specifically, the body 21 of the connector 20 is the core of the entire connection structure, providing mechanical support and fixing functions. The multiple first terminals 22 and the multiple second terminals 23 of the plug end are responsible for electrical connection, respectively, to achieve reliable contact with the busbar 30. By setting multiple terminals, multi-point contact can be achieved, thereby improving the reliability of electrical connection.

[0046] Furthermore, the contacts of the first terminal 22 and the second terminal 23 are in contact with the bus bar 30 respectively, ensuring that the electrical signal or current can be transmitted smoothly. In the direction of the plug-in end, the first contact 221 is located behind the second contact 231, and the positions of the first contact 221 and the second contact 231 are staggered, so that the bus bar 30 can be gradually contacted during the insertion process. The gradual contact design reduces the instantaneous resistance generated during the plug-in and unplugging process, and the plug-in and unplugging process is smoother, avoiding the user's discomfort caused by the instantaneous increase in resistance during the plug-in and unplugging process, and reducing the risk of poor contact or damage caused by plug-in and unplugging difficulties. The pressure on each connector 20 is more uniform and dispersed, reducing mechanical wear and stress concentration, and extending the service life of the connector.

[0047] In a specific embodiment, the second terminal 23 further includes a contact portion 232, and the contact portion 232 is disposed on the second contact 231;

[0048] When viewed in the vertical direction, the width of the contact portion 232 is smaller than the width of the second terminal 23 .

[0049] Specifically, a contact portion 232 is added to the design of the second terminal 23, and the contact portion 232 is directly arranged on the second contact 231 to ensure a dedicated area for electrical connection. The contact portion 232 is responsible for actual electrical contact and transmits current or signals with the bus bar 30, and the width of the contact portion 232 is smaller than the width of the second terminal 23, so that the electrical contact area can be more concentrated.

[0050] Furthermore, the width of the contact portion 232 is smaller than the width of the second terminal 23, which reduces the friction area during plugging and unplugging, thereby reducing the plugging and unplugging resistance and making the plugging and unplugging operation smoother. The narrow design of the contact portion 232 can reduce friction and mechanical stress, and the concentrated contact area can reduce friction, making the plugging and unplugging operation smoother. It prevents excessive mechanical wear and extends the service life of the connector. In addition, the concentrated electrical contact area can distribute current more evenly, reduce local overheating caused by current concentration, and improve the reliability and safety of electrical connection.

[0051] In a specific embodiment, a plurality of the first terminals 22 and a plurality of the second terminals 23 are arranged on the body 21 at intervals.

[0052] Specifically, the first terminal 22 and the second terminal 23 are arranged in a front-to-back distribution and at intervals, which can effectively disperse the mechanical stress during the insertion and removal process, prevent a single terminal from being subjected to excessive stress, thereby reducing the risk of terminal deformation or breakage and extending the service life of the connector. The spaced arrangement reduces electrical interference (such as crosstalk) between adjacent terminals and improves the reliability and stability of the electrical connection. Due to the spaced arrangement, the mechanical stress generated during the insertion process can be dispersed, reducing single-point stress concentration, and making insertion and removal smoother.

[0053] In a specific embodiment, the body 21 includes a first portion 211 and a second portion 212 that fit together, and the plug-in ends of the first portion 211 and the second portion 212 are both provided with a plurality of first terminals 22 and a plurality of second terminals 23 .

[0054] Specifically, the main body 21 is configured to be two parts that fit together, and both parts are provided with the multiple first terminals 22 and second terminals 23 mentioned above. The connector is configured to have two rows of terminals that are spatially symmetrical. Since the plug-in end of the connector is provided with two rows of terminals, it is equivalent to having two contact surfaces in contact with the bus bar 30, which can increase the contact points with the bus bar 30 and improve the stability and reliability of the connection.

[0055] Furthermore, the design of two rows of terminals allows the mechanical stress to be more evenly dispersed on the plug-in end of the connector, avoiding excessive stress on a single terminal. The two-row setting can also ensure that the connector maintains stable contact during insertion and use, thereby effectively improving the contact stability and reliability between the connector and the busbar 30.

[0056] In a specific embodiment, the body 21 further includes a first fixing portion 211a and a second fixing portion 212a;

[0057] The first fixing portion 211a is disposed on the first portion 211, and the second fixing portion 212a is disposed on the second portion 212;

[0058] The first fixing portion 211 a and the second fixing portion 212 a are located on two side surfaces of the body 21 close to the terminal, and are used to limit the opening and closing size between the terminals of the first portion 211 and the second portion 212 .

[0059] Specifically, it is set on both sides of the terminal, and by limiting the opening and closing size between the upper and lower rows of terminals, it ensures that the position of the terminals is relatively fixed during the use of the connector, avoiding unstable or damaged connections caused by excessive or small terminal spacing. It can also prevent loose connections caused by vibration or external forces, and improve the reliability and durability of the connector.

[0060] In a specific embodiment, the bus bar 30 has a contact surface for contacting the first contact point 221 and the second contact point 231, and the housing 10 has a first surface 11 and a second surface 12 that are oppositely disposed and parallel to the contact surface;

[0061] The housing 10 further includes a first extension portion 111 and a second extension portion 121 , wherein the first extension portion 111 is disposed on the first surface 11 , and the second extension portion 121 is disposed on the second surface 12 ;

[0062] The first extension portion 111 and the second extension portion 121 are used to be fixed on an electrical device.

[0063] Specifically, extensions are provided on both sides of the housing 10 that are parallel to the two contact surfaces of the two contacts, and the first extension 111 and the second extension 121 are used to fix the connector to the electrical device to ensure that the connector will not loosen or fall off during use. This enhances the connection stability and reliability between the connector and the electrical device, and avoids interruption or damage to the electrical connection caused by loosening of the connector.

[0064] Furthermore, because the connector needs to be frequently plugged in and out, the extension portion provided on the shell 10 can firmly connect the shell 10 to the electrical equipment, which can prevent loosening and reduce the vibration of the external environment that directly affects the electrical connection between the terminal and the bus bar 30, making the connection more stable.

[0065] In a specific embodiment, the power connector includes two fixing members 40;

[0066] The first extension portion 111 is provided with a first fixing hole 111a, and a fixing member 40 is disposed in the first fixing hole 111a for fixing the first extension portion 111 on the electrical device;

[0067] The second extension portion 121 is provided with a second fixing hole 121a, and another fixing member 40 is disposed in the second fixing hole 121a, and is used to fix the second extension portion 121 on the electrical device;

[0068] When the two fixing members 40 are respectively disposed in the first fixing hole 111a and the second fixing hole 121a and fixed to the electrical equipment, a floating gap 41 is formed between each fixing member 40 and the first fixing hole 111a and the second fixing hole 121a.

[0069] Specifically, during the manufacturing process of the connector 20, due to slight deviations, the connector 20 may be larger in size, and the larger connector 20 may not be able to be inserted into the prefabricated housing 10, which makes it difficult to match the connector 20 with the housing 10, or even makes it impossible to correctly insert the housing 10 or requires too much force to insert. By setting a floating gap 41 between the fixing member 40 and the fixing hole, this size deviation can be effectively dealt with, and the manufacturing tolerance of the connector can be improved.

[0070] Furthermore, the floating gap 41 can tolerate the size deviation of the connector 20 to a certain extent. Even if the connector 20 is too large, the housing 10 can still move outward by floating, so that the connector can be smoothly inserted into the housing 10. During the connector assembly process, the size mismatch problem caused by manufacturing deviation will increase the complexity of assembly. The setting of the floating gap 41 can reduce the assembly difficulty caused by this size mismatch and improve the assembly efficiency. Through the design of the floating gap 41, it can be ensured that even if the size of the connector 20 deviates, the correct assembly of the connector can still be guaranteed, thereby ensuring the assembly quality.

[0071] In a specific embodiment, the fixing member 40 is a screw or a steel sleeve.

[0072] Preferably, the screw, as a common connector 20, has the ability to fix the connector and the electrical device, and the connector can be installed on the device by rotating and tightening. The screw has a simple design and is easy to operate, and can effectively fix the connector, thereby improving the stability and reliability of the connector.

[0073] Preferably, the steel sleeve is a metal sleeve, which is usually used to enhance the durability and stability of the connecting parts and can withstand greater forces and pressures. The use of the steel sleeve can enhance the connection strength between the fixing member 40 and the fixing hole, and improve the durability and vibration resistance of the connector.

[0074] Furthermore, by using screws and steel sleeves as fixing parts 40, the connector can be reliably installed in various application scenarios, while ensuring a floating gap 41 and ensuring a stable connection between the connector and the electrical equipment, thereby improving the quality and performance of the product.

[0075] In a specific embodiment, the first extending portion 111 is perpendicular to the first surface 11 , and the second extending portion 121 is perpendicular to the second surface 12 .

[0076] Specifically, a more solid support is formed between the vertical extension portion and the mounting surface of the device, which effectively prevents the connector from being displaced or loosened due to vibration or other external forces during use, thereby improving the overall stability of the connector.

[0077] Furthermore, the vertical structure design can be used as a protective measure to effectively reduce the impact of external structure vibration and impact on the connector. This design can transfer the force of the connector to a more stable device structure, reducing the damage and wear of the connector caused by external factors. By reducing the impact of external structure vibration and impact on the connector, the frequency of maintenance and replacement is reduced, and the cost of use is reduced.

[0078] A connector assembly includes a power connector as described in any one of the above embodiments. Since this embodiment includes all the features of the above embodiments, this embodiment has all the beneficial effects of the above embodiments, which will not be repeated here.

[0079] 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.
