Description

Technical Field

[0001] This application relates to the field of electrical connection technology, specifically to an electrical connector and electrical equipment. Background Technology

[0002] Electrical connectors are used to connect two electronic components. An electrical connector includes male terminals and female terminals, and the male terminals can be inserted into the female terminals to make contact with them.

[0003] When connecting two electronic components via an electrical connector, the male terminal needs to be inserted into the female terminal. In traditional electrical connectors, the width of the contact area between the male and female terminals hardly changes from the initial insertion of the male terminal to its full insertion into the female terminal. This requires a large pushing force when initially inserting the male terminal into the female terminal, which can easily cause operator fatigue when inserting and removing a large number of connectors. Summary of the Invention

[0004] The purpose of this application is to provide an electrical connector and electrical equipment that solves the problem of requiring a large pushing force when inserting the male terminal into the female terminal.

[0005] To achieve the objectives of this application, the following technical solution is provided:

[0006] In a first aspect, embodiments of this application provide an electrical connector, comprising:

[0007] The male terminal includes an insertion portion and a first retaining portion. The insertion portion is connected to the first retaining portion. The insertion portion includes a first surface and a second surface disposed opposite to each other. The end of the insertion portion away from the first retaining portion is provided with a first notch recessed in the direction of the first retaining portion. The first notch penetrates the first surface and the second surface along a first direction, and the first direction is perpendicular to the recessed direction of the first notch.

[0008] A female terminal is provided for insertion of the insertion portion and contacts the first surface and the second surface.

[0009] In some embodiments, the first notch is along its concave direction, the size of the first notch gradually decreases in a second direction, the second direction is perpendicular to the first direction, and the second direction is perpendicular to the concave direction of the first notch.

[0010] In some embodiments, the ratio of the dimension of the first notch along the second direction to the dimension of the insertion portion along the second direction is between 1:3 and 1:2.

[0011] In some embodiments, the female terminal includes a contact portion and a second retaining portion, the contact portion being connected to the second retaining portion, the end of the contact portion away from the second retaining portion having a second notch recessed in the direction of the second retaining portion, the recessing direction of the second notch being opposite to the recessing direction of the first notch, the contact portion including a third surface and a fourth surface disposed opposite to each other, the second notch penetrating the third surface and the fourth surface along the first direction.

[0012] In some embodiments, the contact portion includes a first spring and a second spring. The first spring has a first region protruding toward the direction of the second spring, and the second spring has a second region protruding toward the first region. The first region and the second region cooperate to clamp a portion of the insertion portion. The first region is in contact with the first surface, and the second region is in contact with the second surface.

[0013] In some embodiments, the portion of the insertion portion that is held between the first region and the second region is located between the first notch and the first retaining portion.

[0014] In some embodiments, the first notch is located between the two side edges of the insertion portion, the two side edges of the insertion portion are arranged along the second direction, and the second notch is located between the two side edges of the contact portion, the two side edges of the contact portion are arranged along the second direction.

[0015] In some embodiments, the second notch includes a first segment, a second segment, and a third segment that are connected along its concave direction. Along the concave direction of the second notch, the size of the first segment gradually decreases in the second direction, while the size of the second segment remains unchanged in the second direction.

[0016] In some embodiments, the dimension of the port of the first notch away from the first retaining portion in the second direction is greater than the dimension of the second segment in the second direction.

[0017] In some embodiments, the end of the insertion portion away from the first retaining portion is provided with a first chamfer.

[0018] In some embodiments, the two sides of the insertion portion are provided with a second chamfer.

[0019] In some embodiments, the electrical connector further includes a first crimping portion connected to one end of the first retaining portion away from the insertion portion. The first crimping portion includes a first conductor clamp and a first insulating clamp, with the first conductor clamp connected between the first retaining portion and the first insulating clamp.

[0020] In some embodiments, the electrical connector further includes a second crimping portion connected to one end of the second retaining portion away from the contact portion. The second crimping portion includes a second conductor clamp and a second insulating clamp, with the second conductor clamp connected between the second retaining portion and the second insulating clamp.

[0021] Secondly, embodiments of this application provide an electrical device, which includes an electrical connector as described in the first aspect.

[0022] In the above solution, one end of the insertion part is provided with a first notch that penetrates the first surface and the second surface. When the insertion part is inserted into the female end, the contact area between the female end and the first surface and the second surface will be smaller, which can reduce the friction between the insertion part and the female end, thereby reducing the thrust required to insert the male end into the female end.

Detailed Implementation

[0031] Electrical connectors enable the electrical connection of two or more electronic components. They offer the advantage of facilitating the connection of electronic components and can also be mass-produced to save on production costs.

[0032] Electrical connectors include male and female terminals, facilitating the connection of two electronic components. One of the two electronic components is connected to the male terminal, and the other is connected to the female terminal. The male terminal is inserted into the female terminal to achieve an electrical connection between the two electronic components.

[0033] Currently, the width of the contact area between the male and female terminals hardly changes during the process from the initial insertion of the male terminal to its complete insertion into the female terminal. This requires a large pushing force when inserting the male terminal into the female terminal, which can easily cause operator fatigue when inserting and removing a large number of connectors.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0036] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0037] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] For ease of description, the length direction of the electrical connector is defined as the X-axis, the width direction as the Y-axis, and the height direction as the Z-axis.

[0039] Please see Figures 1-3 , Figure 1 This is an exploded view of an electrical connector according to an embodiment of this application. Figure 2 for Figure 1 Another structural diagram of the electrical connector in the diagram. Figure 3 An assembly drawing of an electrical connector is provided as an embodiment of this application;

[0040] Figure 4 for Figure 3 A schematic diagram of the electrical connector from another perspective. This application provides an electrical connector including a male terminal 100 and a female terminal 200, which are in contact with each other.

[0041] Please refer to the embodiments provided in this application. Figure 1 The male terminal 100 includes an insertion portion 110, a first holding portion 120, and a first crimping portion 130. The first holding portion 120 is connected between the insertion portion 110 and the first crimping portion 130. The insertion portion 110 can be a contact piece. The first crimping portion 130 is used to connect to the wires of an electronic component. The first crimping portion 130 can fix the wires of the electronic component and make an electrical connection with them. The first holding portion 120 is a transition structure between the insertion portion 110 and the first crimping portion 130. The first holding portion 120 can be fixedly connected to both the insertion portion 110 and the first crimping portion 130, and the first holding portion 120 is conductive.

[0042] Please see Figure 1The female terminal 200 includes a contact portion 210, a second holding portion 220, and a second crimping portion 230, with the second holding portion 220 connected between the contact portion 210 and the second crimping portion 230. The contact portion 210 is used to clamp the insertion portion 110, and the second crimping portion 230 is used to connect to the wires of the electronic component. The second crimping portion 230 can fix the wires of the electronic component and make an electrical connection with them. The second holding portion 220 is a transition structure between the contact portion 110 and the second crimping portion 230. The second holding portion 220 can be fixedly connected to the insertion portion 110 and the second crimping portion 230, and the second holding portion 220 is conductive.

[0043] Please refer to the embodiments provided in this application. Figure 2 The insertion portion 110 of the male terminal 100 is inserted into the contact portion 210 of the female terminal 200, and the contact portion 210 can hold the insertion portion 110.

[0044] The insertion portion 110 has a first notch 111 at its end away from the first holding portion 120, and the first notch 111 is recessed in the direction of the first holding portion 120. The presence of the first notch 111 in the insertion portion 110 can reduce the contact area when the insertion portion 110 is just inserted into the contact portion 210, thereby reducing the force required to insert the insertion portion 110 into the contact portion 210. The recessed direction of the first notch 111 is the X-axis.

[0045] In the embodiments provided in this application, the insertion portion 110 further includes a first surface and a second surface disposed opposite to each other. The first surface and the second surface can be arranged along a first direction (Z-axis), and a first notch 111 penetrates through the first surface and the second surface. The first surface and the second surface can contact the contact portion 210 of the female terminal 200.

[0046] Since the first notch 111 penetrates the first surface and the second surface, the contact area between the insertion part 110 and the contact part 210 is reduced, which can reduce the friction when the insertion part 110 is just inserted into the female terminal 200, thereby reducing the thrust of inserting the insertion part 110 into the female terminal 200.

[0047] In the embodiments provided in this application, along the recessed direction of the first notch 111, the size of the first notch 111 gradually decreases in the second direction (Y-axis). It can be understood that during the insertion of the insertion part 110 into the female terminal 200, the width of the insertion part 110 contacting the contact part 210 in the second direction (Y-axis) gradually increases, and the contact area between the insertion part 110 and the contact part 210 gradually increases. Therefore, the force required to insert the male terminal 100 into the contact part 210 increases progressively. Initially, the force required to insert the male terminal 100 into the contact part 210 increases gradually. When the insertion part 110 is inserted into the contact part 210, the contact area between the insertion part 110 and the contact part 210 is small, and the friction between the insertion part 110 and the contact part 210 is relatively small. This makes it easier for the insertion part 110 to be inserted into the contact part 210. It also reduces the risk of failure due to wear during the insertion and removal process. The insertion part 110 is provided with a first notch 111, which can reduce the amount of material required when manufacturing the male terminal 100, and further reduce the cost of the male terminal 100.

[0048] In the embodiments provided in this application, the ratio of the size of the port of the first notch 111 away from the first holding portion 120 in the second direction to the size of the insertion portion 110 in the second direction is between 1:3 and 1:2. In the embodiments provided in this application, if the ratio of the size of the port of the first notch 111 away from the first holding portion 120 in the second direction to the size of the insertion portion 110 in the second direction is 1:3, compared to a conventional insertion portion 110, the contact area between the insertion portion 110 and the female terminal 200 is almost 1 / 3 smaller, significantly reducing the friction between the insertion portion 110 and the female terminal 200. If the ratio of the size of the port of the first notch 111 away from the first holding portion 120 in the second direction to the size of the insertion portion 110 in the second direction is 1:2, compared to a conventional insertion portion 110, the contact area between the insertion portion 110 and the female terminal 200 is almost 1 / 2 smaller, significantly reducing the friction between the insertion portion 110 and the female terminal 200. It should be noted that the ratio of the size of the port of the first notch 111 away from the first retaining part 120 in the second direction to the size of the insertion part 110 in the second direction is between 1:3 and 1:2. This can effectively reduce the pushing force required to push the insertion part 110 into the contact part 210, and can also maintain high engagement stability and good engagement feel when the insertion part 110 is inserted into the contact part 210.

[0049] In the embodiments provided in this application, the two side edges of the insertion part 110 are arranged along the second direction (Y-axis), the first notch 111 is located between the two side edges of the insertion part 110, and there is a gap between the bottom of the first notch 111 and the end of the insertion part 110 connected to the first holding part 120.

[0050] In the embodiments provided in this application, when the insertion part 110 is fully inserted into the contact part 210, the insertion part 110 and the contact part 210 are electrically connected. After the insertion part 110 and the contact part 210 are energized, since the insertion part 110 is provided with a first notch 111, the surface area of ​​the insertion part 110 is increased, which can improve the heat dissipation capacity of the insertion part 110, thereby improving the heat dissipation capacity of the electrical connector.

[0051] In the embodiments provided in this application, the end of the insertion part 110 away from the first holding part 120 is provided with a first chamfer 112. The first chamfer 112 serves as a guide to facilitate the insertion part 110 extending into the contact part 210.

[0052] In the embodiments provided in this application, the two sides of the insertion part 110 are provided with a second chamfer 113, which serves as a guide to facilitate the insertion part 110 extending into the contact part 210.

[0053] In the embodiments provided in this application, the first crimping portion 130 includes a first conductor clamp 131 and a first insulating clamp 132, wherein the first conductor clamp 131 is connected between the first holding portion 120 and the first insulating clamp 132. Specifically, along the arrangement direction of the first conductor clamp 131 and the first insulating clamp 132, the cross-section of the first conductor clamp 131 is U-shaped, and the cross-section of the first insulating clamp 132 is U-shaped. The first conductor clamp 131 is used to clamp the core wire of the conductor and is electrically connected to the core wire. The first insulating clamp 132 is used to clamp the insulating sheath of the conductor to fix the position of the conductor.

[0054] In the embodiments provided in this application, one end of the contact portion 210 is provided with a second notch 211 recessed toward the other end of the contact portion 210, and the recessed direction of the second notch 211 is opposite to the recessed direction of the first notch 111. The two side edges of the second notch 211 are arranged along a second direction (Y-axis), and the second notch 211 is located between the two side edges of the contact portion 210. The contact portion 210 may include a third surface and a fourth surface disposed opposite to each other, and the second notch 211 penetrates the third surface and the fourth surface along a first direction. The third surface and the fourth surface may be arranged along the first direction. It is understood that by providing the second notch 211 in the contact portion 210, the contact area between the contact portion 210 and the first surface and the second surface can be reduced, thereby reducing the thrust required for the insertion portion 110 to be inserted into the contact portion 210, and further reducing the risk of failure of the insertion portion 110 and the contact portion 210 due to wear during the insertion and removal process. By providing the second notch 211 in the contact portion 210, the material requirement of the female terminal 200 can also be reduced, thereby reducing the cost of the female terminal 200.

[0055] In the embodiments provided in this application, there is a gap between the bottom of the second notch 211 and the end of the contact portion 210 that is connected to the second holding portion 220, and the contact portion 210 can be integrally formed.

[0056] Please refer to the embodiments provided in this application. Figure 1 The second notch 211 includes, along its recessed direction, a first segment 211a, a second segment 211b, and a third segment 211c connected in sequence. The second segment 211b is located between the first segment 211a and the third segment 211c. The first segment 211a is located at the end of the contact portion 210 away from the second holding portion 220. The third segment 211c has a certain distance between it and the end of the contact portion 210 connected to the second holding portion 220.

[0057] In the embodiments provided in this application, along the recessed direction of the second notch 211, the size of the first segment 211a in the second direction (Y-axis) gradually decreases, the size of the second segment 211b in the second direction (Y-axis) remains unchanged, and the size of the third segment 211c in the second direction (Y-axis) can first increase and then decrease.

[0058] In the embodiments provided in this application, the contact portion 210 can be a clamping structure. Specifically, the contact portion 210 can include a first spring 212 and a second spring 213. The first spring 212 and the second spring 213 can be arranged at intervals. The first spring 212 has a first region 212a that protrudes in the direction of the second spring 213, and the second spring 213 has a second region that protrudes in the direction of the first spring. When the insertion portion 110 is inserted into the contact portion 210, the first spring 212 and the second spring 213 clamp the insertion portion 110. The first region 212a of the first spring 212 and the second region 213a of the second spring 213 are in contact with the first surface and the second surface of the insertion portion 110, respectively.

[0059] In the embodiments provided in this application, the surface of the first spring 212 facing away from the second spring 213 is the third surface, and the surface of the second spring 213 facing away from the first spring 212 is the fourth surface.

[0060] In the embodiments provided in this application, the contact portion 210 may include a shell portion, a first spring piece 212, and a second spring piece 213. The first spring piece 212 and the second spring piece 213 are symmetrically arranged along a first direction (Z-axis). The first spring piece 212 and the second spring piece 213 are connected to the shell portion. The end of the first spring piece 212 away from the second holding portion 220 is provided with a third notch recessed in the direction of the second holding portion 220. The third notch penetrates the first spring piece 212 along the first direction. The end of the second spring piece 213 away from the second holding portion 220 is provided with a fourth notch recessed in the direction of the second holding portion 220. The fourth notch penetrates the second spring piece 213 along the first direction. The third notch and the fourth notch constitute the second notch 211.

[0061] In the embodiments provided in this application, when the insertion part 110 is fully inserted into the contact part 210, the area of ​​the insertion part 110 that contacts the first region 212a and the second region 213a is located between the first notch 111 and the end of the insertion part 110 connected to the first holding part 120.

[0062] In the embodiments provided in this application, the first region 212a includes a first portion 212b and a second portion 212c arranged along the second direction (Y-axis), the first portion 212b and the second portion 212c being located on both sides of the second gap 211, and the second region 213a includes a third portion 213b and a fourth portion 213c arranged along the second direction (Y-axis), the third portion 213b and the fourth portion 213c being located on both sides of the second gap 211.

[0063] In the embodiments provided in this application, the dimension of the port of the first notch 111 away from the first retaining portion in the second direction is larger than the dimension of the second segment in the second direction. When the insertion portion is just inserted into the contact portion, the contact area between the insertion portion and the first region can be smaller than the contact area of ​​the first region, and the contact area between the insertion portion and the second region can be smaller than the contact area of ​​the second region. Furthermore, since the dimension of the first notch gradually decreases in the second direction along its concave direction, the contact area between the insertion portion and the contact portion can gradually increase during the insertion process, thereby gradually increasing the thrust required for the insertion portion to insert into the contact portion. Under the condition that the maximum frictional force between the insertion portion and the contact portion remains unchanged, it is easier for the insertion portion to be inserted into the contact portion.

[0064] In the embodiments provided in this application, by providing a second notch 211 in the contact portion 210, the area of ​​the first region 212a and the second region 213a can be reduced, thereby reducing the contact area between the contact portion 210 and the insertion portion 110, and further reducing the frictional force of the insertion portion 110 when it is inserted into the contact portion 210, so that the insertion portion 110 can be inserted into the contact portion 210 more easily.

[0065] In the embodiments provided in this application, the size of the insertion part 110 in the second direction is greater than the size of the first spring 212 in the second direction, and the size of the first spring 212 in the second direction is equal to the size of the second spring 213 in the second direction.

[0066] When the insertion part 110 is fully inserted into the contact part 210, the projection of the first region 212a of the first spring 212 along the Z-axis is completely on the first surface, and the projection of the second region 213a of the second spring 213 along the Z-axis is completely on the second surface.

Figure 5 for Figure 3 This is a schematic diagram of the structure of the Zhongdian connector from another perspective. During the insertion of the insertion portion 110 into the contact portion 210, when the end of the insertion portion 110 away from the first retaining portion 120 is inserted between the first spring 212 and the second spring 213, regions A and B on the first surface near the end of the insertion portion 110 away from the first retaining portion 120 contact the first portion 212b and the second portion 212c, respectively. Regions C and D on the second surface near the end face of the insertion portion 110 away from the first retaining portion 120 contact the third portion 213b and the fourth portion 213c, respectively. It should be noted that regions A and B are distributed along the second direction (Y-axis) on both sides of the first notch 111, and regions C and D are also distributed along the second direction on both sides of the first notch 111. Regions A and C are arranged along the first direction (Z-axis), and can be symmetrically arranged. Regions B and D are also arranged along the first direction (Z-axis), and can be symmetrically arranged.

[0068] When the insertion part 110 is fully inserted into the contact part 210, regions E and F on the first surface, located between the first notch 111 and the end face where the insertion part 110 connects to the first retaining part 120, respectively, contact the first part 212b and the second part 212c. Regions G and H on the second surface, located between the first notch 111 and the end face where the insertion part 110 connects to the first retaining part 120, respectively, connect to the third part 213b and the fourth part 213c. It should be noted that regions E and F are arranged along the second direction (Y-axis), and regions G and H are arranged along the second direction (Y-axis). Regions E and G are arranged along the first direction (Z-axis), and regions E and G can be symmetrical to each other; regions F and G are also arranged along the first direction (Z-axis), and regions F and G can be symmetrical to each other.

[0069] The second crimping portion 230 includes a second conductor clamp 231 and a second insulating clamp 232. The second conductor clamp 231 is connected between the second holding portion 220 and the second insulating clamp 232. Specifically, along the arrangement direction of the second conductor clamp 231 and the second insulating clamp 232, the cross-section of both the second conductor clamp 231 and the second insulating clamp 232 is U-shaped. The second conductor clamp 231 is used to clamp the core wire of the conductor and is electrically connected to the core wire. The second insulating clamp 232 is used to clamp the insulating sheath of the conductor to fix the position of the conductor.
