[0001] [Related Application] This application claims the priority of a Chinese patent application with the patent application number 202111665882.X, the filing date of December 30, 2021, and the invention title of "Electrical Connector".

[0002] This application relates to the technical field of connectors, particularly to electrical connectors.

Background Art

[0003] An electronic connector, generally also called an electrical connector, is a conductor device for connecting two conductors in a circuit and allowing current or signals to flow from one conductor to the other.

[0004] In the prior art, the conductive unit of an electrical connector often adopts the following two modes. One is an insertion hole type conductive unit of a cylindrical electrical connection device. Such a conductive unit adopts a machining method, with a complex production process, high cost, limited current-carrying capacity, and is restricted by the outer dimensions of the conductive unit. Its connector dimensions are larger than those of a connector with a chip-type conductive unit of the same specification, and it cannot meet the requirements demanded by the market such as high performance, low cost, and weight reduction of components. The other is a chip-type conductive unit. Such a conductive unit always adopts a mode where a circlip wraps the lead. After the circlip and the lead are fixed, it can only be fitted into the electrical connection device from a single angle, resulting in a low utilization rate of the conductive unit and being disadvantageous for mass production of the conductive unit.

Means for Solving the Problems

[0006] This invention can be realized by employing the following technical solutions.

[0007] The present invention relates to a housing having a first opening for inserting a first electrical connector and a second opening for inserting a second electrical connector, which are spaced apart, and the side wall facing the first opening is provided with a first insertion portion. A first conductive unit electrically connectable to a first electrical connection device and / or a second electrical connection device, wherein at least a portion of the first conductive unit is housed within a housing, Includes, The first or second electrical connector provides an electrical connector that is electrically connected to at least some of the housed first conductive units when inserted into the housing from outside the housing via a first insertion portion.

[0008] Compared to the prior art, the features and advantages of this invention are as follows:

[0009] The electrical connector according to the present invention has a first insertion portion on the side wall of the housing facing the first opening, so that the first electrical connector and / or the second electrical connector can be electrically connected to at least a portion of the first conductive unit housing the first electrical connector and / or the second electrical connector when they are inserted into the housing from outside the housing through the first insertion portion. In addition to the first electrical connector and the second electrical connector being inserted into the housing from the first opening and the second opening, respectively, and being electrically connected to the first conductive unit, the first electrical connector and / or the second electrical connector can also be inserted through the first insertion portion and electrically connected to the first conductive unit. As a result, the electrical connector according to the present invention, with the above setting, makes it possible to achieve mating of the first electrical connector and / or the second electrical connector with the electrical connector at at least two angles (for example, 90 degrees and 180 degrees).

[Modes for carrying out the invention]

[0012] Embodiments of the present application will be described below with reference to specific examples, but those skilled in the art will readily understand other advantages and effects of the present application from the contents disclosed herein. Furthermore, the present application may be implemented or applied in other different specific examples and may be modified and altered in various ways within the scope of the rights protected by the present application.

[0013] Based on the above advantages, preferred embodiments are disclosed below to allow for a further understanding of the present application, and the technical solutions of the present application and the effects achieved thereby are described in detail below with reference to the drawings and reference numerals.

[0014] To facilitate understanding of the electrical connector provided in this application, we will first explain the application scenarios of the electrical connector. The electrical connector according to this application is for connecting two conductors (for example, an electrical connection device).

[0015] As used in this specification, a cantilever beam is defined as a beam where one end is fixed and the other end is free.

[0016] As shown in FIGS. 1 to 3, the electrical connector according to the present application includes a housing 1 and a first conductive unit 2. The housing 1 has a first opening 11 for inserting a first electrical connection device 8 provided at an interval, and a second opening 12 for inserting a second electrical connection device 9. A first insertion portion 13 is provided on a side wall of the housing 1 facing the first opening 11. The first conductive unit 2 can be electrically connected to the first electrical connection device 8 and / or the second electrical connection device 9, and at least a part thereof is accommodated in the housing 1. In a state where the first electrical connection device 8 or the second electrical connection device 9 is inserted into the housing 1 from the outside of the housing 1 through the first insertion portion 13, the first electrical connection device 8 or the second electrical connection device 9 can be electrically connected to at least a part of the accommodated first conductive unit 2.

[0017] By providing the first insertion portion 13 on the side wall of the housing 1 facing the first opening 1, in a state where the first electrical connection device 8 or the second electrical connection device 9 is inserted into the housing 1 from the outside of the housing 1 through the first insertion portion 13, the first electrical connection device 8 or the second electrical connection device 9 can be electrically connected to at least a part of the accommodated first conductive unit 2. Therefore, in addition to being inserted into the housing 1 from the first opening 11 and the second opening 12 respectively and being electrically connected to the first conductive unit 2, the first electrical connection device 8 and the second electrical connection device 9 can also be inserted into the housing 1 from the first insertion portion 13 in the first opening 11 and be electrically connected to the first conductive unit 2. Thus, with the above structure, the electrical connector according to the present application can realize that the first electrical connection device 8 and / or the second electrical connection device 9 is fitted to the electrical connector at at least two different angles.

[0018] Specifically, the housing 1 may have a hollow rectangular parallelepiped structure, and the first insertion portion 13 may be a notch provided in the housing 1. The notch communicates with the first opening 11, and at least a part of the first conductive unit 2 is provided in the housing 1 by means such as welding, adhesion, screw connection or locking. When actually used, the first electrical connection device 8 and the second electrical connection device 9 can be electrically connected to the first conductive unit 2 of the housing 1 by being inserted into the housing 1 from the first opening 11 and the second opening 12 respectively. Optionally, the first electrical connection device 8 or the second electrical connection device 9 can be inserted into the housing 1 from the first insertion portion 13 communicating with the first opening 11, so that the first electrical connection device 8 or the second electrical connection device 9 inserted through the first insertion portion 13 can also be electrically connected to the first conductive unit 2 in the housing 1.

[0019] Furthermore, as shown in FIGS. 1 and 2, a second insertion portion 14 is further provided on the side wall of the housing 1 facing the first opening 11, and the second insertion portion 14 is provided opposite to the first insertion portion 13 along a direction perpendicular to the direction O in which the first electrical connection device 8 or the second electrical connection device 9 is inserted into the first opening 11. Specifically, the second insertion portion 14 may be a notch provided in the housing 1 and communicating with the first opening 11.

[0020] In the present application, by providing the first insertion portion 13 and the second insertion portion 14 communicating with the first opening 11 on the side wall of the housing 1 facing the first opening 11, in addition to the first electrical connection device 8 or the second electrical connection device 9 being able to be inserted into the housing 1 from the first opening 11, the second opening 12 or the first insertion portion 13, it can also be inserted into the housing 1 from the second insertion portion 14, thereby realizing electrical connection with the first conductive unit 2 from multiple angles and increasing the fitting methods between the first electrical connection device 8 or the second electrical connection device 9 and the electrical connector.

[0021] The material of the housing 1 may be plastic or metal, and may be a material with good conductivity or poor conductivity, for example, steel, or a material containing steel. The first insertion portion 13 and / or second insertion portion 14 according to the present invention allow the first electrical connector 8 and the second electrical connector 9 to be inserted into the housing 1 along direction O, respectively, while, as shown in Figure 5, it is also possible to insert the first electrical connector 8 or the second electrical connector 9 from the side of the housing 1. It is also clear that the first electrical connector 8 or the second electrical connector 9 can be selectively inserted along the oblique direction P of the housing 1. This further enriches the mating method between the first electrical connector 8 or the second electrical connector 9 and the electrical connector, and on the other hand, the present invention is easier to process, and for example, the first insertion portion 13 and / or second insertion portion 14 can be formed simply by directly cutting the end of the first opening 11 of the housing 1.

[0022] In one feasible embodiment, the first insertion portion 13 or the second insertion portion 14 may be a hole formed in the side wall of the housing 1, for example, a rectangular through-hole, located near the first opening 11 or the second opening 12 of the housing 1. In specific implementation, the peripheral wall of the hole can be positioned relative to the first electrical connection device 8 or the second electrical connection device 9. Furthermore, in some embodiments, to achieve waterproof and dustproof effects, a waterproof plate or dustproof plate may be hinged to the peripheral wall of the first insertion portion 13 and / or the second insertion portion 14 in the housing 1, and the waterproof or dustproof effect is achieved by installing the waterproof plate or dustproof plate to seal the first insertion portion 13 or the second insertion portion 14.

[0023] Furthermore, as shown in Figure 4, the housing 1 has a mounting opening 15 for inserting the first conductive unit 2. When the first conductive unit 2 is inserted into the housing 1 through the mounting opening 15, the mounting opening 15 can be closed by bending the side wall of the housing 1 located at the mounting opening 15. By providing the mounting opening 15, the first conductive unit 2 can be quickly inserted into the housing 1, making assembly easy and attachment / detachment easy.

[0024] Specifically, the housing 1 is in a plate shape before molding, and when bent along the width direction Q of the plate, it can form a roughly "bent" shape structure, and the opening of this "bent" shape structure is the mounting opening 15. When assembling the electrical connector, the first conductive unit 2 is inserted directly into the housing 1 from the outside of the housing 1 through the mounting opening 15, and then the mounting opening 15 is closed.

[0025] In this application, the housing 1 includes a first side 17 and a second side 18 that are arranged opposite to each other along the width direction Q before being formed, and one of the first side 17 and the second side 18 is provided with a dovetail projection 171 by, for example, welding, bonding or integral press molding, and the other of the first side 17 and the second side 18 is provided with a dovetail groove 181 that matches the shape of the projection 171, so that the projection 171 can engage with the dovetail groove 181.

[0026] Furthermore, as shown in Figures 11 and 12, the housing 1 further includes a clamping member 16 for applying a pre-tightening force to the first conductive unit 2. By providing the clamping member 16, the first electrical connector 8 or the second electrical connector 9 inserted into the housing 1 can be clamped more firmly, ensuring connection reliability of the electrical connector in a vibrating environment.

[0027] In this application, the clamp member 16 includes at least one first housing elastic arm 161 located in the first opening 11 and at least one second housing elastic arm 162 located in the second opening 12. Of these, the first housing elastic arm 161 includes a first free end 1611 that can enter the housing 1 and contact the first conductive unit 2, and the second housing elastic arm 162 includes a second free end 1622 that can enter the housing 1 and contact the first conductive unit 2.

[0028] Specifically, the first housing elastic arm 161 and the second housing elastic arm 162 may be located on the same side of the housing 1, for example, on the upper surface of the housing 1 as shown in Figure 1, or the first housing elastic arm 161 and the second housing elastic arm 162 may be located on different sides of the housing 1, for example, the first housing elastic arm 161 may be located on the upper surface of the housing 1 and the second housing elastic arm 162 may be located on the lower surface of the housing 1.

[0029] As an example, a first electrical connector 8 is inserted into the housing 1 through the first opening 11 and electrically connected to the first conductive unit 2, and a second electrical connector 9 is inserted into the housing 1 through the second opening 12 and electrically connected to the first conductive unit 2. By providing the clamp member 16, as the first electrical connector 8 is inserted into the first opening 11, the first electrical connector 8 has a certain thickness, so as shown in Figure 12, the first electrical connector 8 can move the first conductive unit 2 along the thickness direction H of the housing 1 toward the inner wall of the adjacent housing 1. At this time, the first housing elastic arm 161 located in the first opening 11 grips the first electrical connector 8, and similarly, the second housing elastic arm 162 grips the second electrical connector 9 inserted into the second opening 12 more tightly.

[0030] The pressure range applied from the first housing elastic arm 161 to the first electrical connection device 8 is 0.3N to 95N, and the pressure range applied from the second housing elastic arm 162 to the second electrical connection device 9 is 0.3N to 95N.

[0031] To verify the effect of pressure applied from the first housing elastic arm 161 to the first electrical connector 8 on the contact resistance between the first housing elastic arm 161 and the first electrical connector 8, or the effect of pressure applied from the second housing elastic arm 162 to the second electrical connector 9 on the contact resistance between the second housing elastic arm 162 and the second electrical connector 9, the applicant conducted tests. Using the pressure applied from the first housing elastic arm 161 to the first electrical connector 8 as an example, the applicant selected a first housing elastic arm 161 and a first electrical connector 8 of the same shape and dimensions, and observed the contact resistance between the first housing elastic arm 161 and the first electrical connector 8 by designing different pressures between them.

[0032] Regarding the contact resistance detection method, a microohmmeter is used to measure the resistance at the contact point between the first housing elastic arm 161 and the first electrical connection device 8, and the value of the microohmmeter is read. In this embodiment, the value when the contact resistance is less than 50 μΩ is considered the ideal value.

[0033] Table 1: Effect of different pressures on contact resistance between housing elastic arm and electrical connector

[0034] [Table 1]

[0035] As can be seen from Table 1, if the pressure between the first housing elastic arm 161 and the first electrical connector 8 is less than 0.3N, the coupling force is too weak, causing the contact resistance between them to be higher than the ideal value and failing to meet the requirements. If the pressure between the first housing elastic arm 161 and the first electrical connector 8 is greater than 95N, the contact resistance does not decrease significantly, and material selection and processing become more difficult. Furthermore, if the pressure is too high, it can also damage the first electrical connector 8. Therefore, the applicant set the pressure range applied from the first housing elastic arm 161 to the first electrical connector 8 to 0.3N to 95N, and the pressure range applied from the second housing elastic arm 162 to the second electrical connector 9 to 0.3N to 95N.

[0036] Furthermore, the applicant has found that when the pressure between the first housing elastic arm 161 and the first electrical connector 8 is greater than 0.5N, the contact resistance between the first housing elastic arm 161 and the first electrical connector 8 is relatively good and tends to decrease quickly. When the pressure between the first housing elastic arm 161 and the first electrical connector 8 is less than 50N, the manufacturing, installation, and use of the conductive elastic piece are all convenient and the cost is low. For this reason, the applicant prefers that the pressure range applied from the first housing elastic arm 161 to the first electrical connector 8 be 0.5N to 50N, and that the pressure range applied from the second housing elastic arm 162 to the second electrical connector 9 be 0.5N to 50N.

[0037] In one embodiment of the present invention, as shown in Figures 5 to 7 and Figure 1, the electrical connector further includes a fixing member 3 for fixing the housing 1 and the first conductive unit 2, the fixing member 3 being provided between the housing 1 and the first conductive unit 2. By providing the fixing member 3, not only is it easier to attach and detach the first conductive unit 2, but the position of the first conductive unit 2 is also restricted.

[0038] In one feasible embodiment, as shown in Figure 6, the fixing member 3 includes a first fixing portion 31 and a first fixing fitting portion 32 that are detachably connected. The first fixing portion 31 is a first convex member provided on the first conductive unit 2 by means of, for example, welding, bonding, screw connection, locking or integral press molding, and the first fixing fitting portion 32 is a first recessed member opened in the housing 1.

[0039] In another feasible embodiment, the fixing member 3 includes a first fixing portion 31 and a first fixing fitting portion 32 that are detachably connected. The first fixing portion 31 is a first convex member provided on the housing 1 by, for example, welding, bonding, screw connection, locking or integral press molding, and the first fixing fitting portion 32 is a first recessed member opened in the first conductive unit 2.

[0040] By providing the first fixing portion 31 and the first fixing fitting portion 32, the structure is simple, and the first conductive unit 2 and the housing 1 can be quickly attached and detached by hand without the use of other tools (e.g., strips or welding rods).

[0041] In one embodiment of the present invention, as shown in Figures 8 and 9, two first conductive units 2 are provided inside the housing 1, and the two first conductive units 2 are spaced apart along the thickness direction H of the housing 1. By providing two first conductive units 2, the first electrical connector 8 and the second electrical connector 9 are clamped in both directions. Compared to an electrical connector having only one first conductive unit 2, by providing two first conductive units 2, taking a chip-type electrical connector as an example, both sides of the chip-type electrical connector can be brought into contact with the first conductive units 2, improving the reliability of the electrical connector being electrically connected to the first conductive units 2.

[0042] Furthermore, as shown in Figures 7 to 9, a strip-shaped support portion 4 is connected between the two first conductive units 2, and the support portion 4 is located on the same side of the two first conductive units 2. By providing the support portion 4, the processing speed of the first conductive units 2 can be improved. Specifically, before forming the housing 1, the processing of the two first conductive units 2, which are on the same plane, can be completed simultaneously by folding them in half using the support portion 4. In addition, since the support portion 4 is located on the same side of the two upper and lower first conductive units 2, it is also convenient for processing the two first conductive units 2, further improving the processing speed. Furthermore, since the support portion 4 is connected to the same side of the two first conductive units 2, each first conductive unit 2 corresponds to a cantilever structure, meaning that under the action of external pressure, the two first conductive units 2 can move closer to each other and deform along the thickness direction H of the housing 1, reducing their volume. Additionally, it becomes easier to insert the two first conductive units 2 into the housing 1 through the mounting opening 15 without interfering with the housing 1.

[0043] In this application, as shown in Figure 9, the first conductive unit 2 includes a plurality of first elastic arms 21 located in the first opening 11, the plurality of first elastic arms 21 being spaced apart along a direction Q perpendicular to the direction in which the first electrical connection device 8 or the second electrical connection device 9 is inserted into the first opening, and a first gap 22 exists between pairs of adjacent first elastic arms 21.

[0044] By providing at least two first elastic arms 21 spaced apart along a direction Q perpendicular to the direction in which the first electrical connector 8 or the second electrical connector 9 is inserted into the first opening, material is saved and manufacturing costs are reduced. Furthermore, because the amount of material is reduced, the contact area with the first electrical connector 8 is reduced, which effectively reduces the temperature rise due to contact (also called the temperature threshold) and the resistance due to contact.

[0045] Specifically, the width of the first gap 22 is 1% to 100% of the width of the first elastic arm 21.

[0046] To investigate the effect of the distance between adjacent first gaps 22 on the contact resistance of an electrical connector, an electrical connector consisting of a first conductive unit 2 and a housing 1 with the same shape and dimensions, a first electrical connection device 8 and a second electrical connection device 9 with the same shape and dimensions were selected, and the electrical connector was connected to the second electrical connection device 9, and the contact resistance between the first electrical connection device 8 and the electrical connector was observed.

[0047] Regarding the contact resistance detection method, a microohmmeter is used to measure the resistance at the contact point between the first electrical connection device 8 and the electrical connector, and the value of the microohmmeter is read. In this embodiment, the value when the contact resistance is less than 50 μΩ is considered the ideal value.

[0048] Table 2: Effect of the spacing distance (width) of the first gap 22 on the contact resistance between the first electrical connection device 8 and the electrical connector structure.

[0049] [Table 2]

[0050] As can be seen from Table 2, if the distance (width) of the first gap 22 is greater than 100% of the width of the first elastic arm 21, the contact resistance is greater than 50 μΩ, thus failing to meet the requirements. Furthermore, conventional manufacturing methods for electrical connector structures are pressing or cutting, and if the distance (width) of the first gap 22 is too narrow, it becomes difficult to manufacture. For these reasons, the distance (width) of the first gap 22 is set to 1% to 100% of the width of the first elastic arm 21.

[0051] Furthermore, as shown in Figure 9, each first elastic arm 21 includes a first curved section 211 and a first connecting section 212 that are sequentially connected from the first opening 11 toward the second opening 12, with the first curved section 211 being inclined toward the outer edge of the first opening 11.

[0052] By providing the first curved section 211 at an angle toward the outer edge of the first opening 11, the electrical connector inserted into the housing 1 through the first opening 11 can more easily contact the first conductive unit 2, and the electrical connector is gripped more firmly. This improves the connection strength between the electrical connector and the electrical connector, i.e., improves the reliability of the electrical connector in use. Furthermore, because the first curved section 211 is provided at an angle toward the outer edge of the first opening 11, the contact area between the connection point between the first curved section 211 and the first connection section 212 of the first conductive unit 2 and the electrical connector is reduced, i.e., the force-receiving area of ​​the electrical connector is reduced. During use, the stronger the pressure effect on the electrical connector, the more firmly the electrical connector will be clamped. When inserting the electrical connector, the force applied to the electrical connector is mitigated, the force applied to the electrical connector is distributed, an appropriate insertion force is maintained, i.e., the electrical connector can be inserted more easily.

[0053] Furthermore, as shown in Figure 9, the first conductive unit 2 further includes a plurality of second elastic arms 24 located in the second opening 12, the plurality of second elastic arms 24 being spaced apart along a direction Q perpendicular to the direction in which the first electrical connector 8 or the second electrical connector 9 is inserted into the second opening 12, and a second gap 25 exists between pairs of adjacent second elastic arms 24. Of these, the plurality of second elastic arms 24 are connected to the plurality of first elastic arms 21 via the first terminal body 23.

[0054] This invention saves material and reduces manufacturing costs by providing at least a plurality of second elastic arms 24 at intervals along a direction Q perpendicular to the direction in which the first electrical connector 8 or the second electrical connector 9 is inserted into the second opening 12. Furthermore, because the amount of material is reduced, the contact area with the second electrical connector 9 is reduced, which can effectively reduce the temperature rise due to contact (also called the temperature threshold) and the resistance due to contact.

[0055] In one embodiment, the width of the second gap 25 is 1% to 100% of the width of the second elastic arm 24.

[0056] To investigate the effect of the spacing distance (width) of the adjacent second gap 25 on the contact resistance of the electrical connector, an electrical connector consisting of a first conductive unit 2 and housing 1 with the same shape and dimensions, a first electrical connection device 8 and a second electrical connection device 9 with the same shape and dimensions were selected, the electrical connector was connected to the first electrical connection device 8, and the contact resistance between the second electrical connection device 9 and the electrical connector was observed.

[0057] Regarding the contact resistance detection method, a microohmmeter is used to measure the resistance at the contact point between the second electrical connection device 9 and the electrical connector, and the value of the microohmmeter is read. In this embodiment, the value when the contact resistance is less than 50 μΩ is considered the ideal value.

[0058] Table 3: Influence of the spacing distance (width) of the second gap 25 on the contact resistance between the second electrical connection device 9 and the electrical connector structure.

[0059] [Table 3]

[0060] As can be seen from Table 3, if the distance (width) of the second gap 25 is greater than 100% of the width of the second elastic arm 24, the contact resistance is greater than 50 μΩ, thus failing to meet the requirements. Furthermore, conventional manufacturing methods for electrical connector structures are pressing or cutting, and if the distance (width) of the second gap 25 is too narrow, it becomes difficult to manufacture. For these reasons, the distance (width) of the second gap 25 is set to 1% to 100% of the width of the second elastic arm 24.

[0061] Furthermore, as shown in Figure 9, each second elastic arm 24 includes a second curved section 241 and a second connecting section 242 that are sequentially connected from the second opening 12 toward the first opening 11, with the second curved section 241 being inclined toward the outer edge of the second opening 12.

[0062] By providing the second curved section 241 at an angle toward the outer edge of the second opening 12, the electrical connector inserted into the housing 1 through the second opening 12 can more easily contact the first conductive unit 2, and the electrical connector is gripped more firmly. This improves the connection strength between the electrical connector and the electrical connector, i.e., improves the reliability of the electrical connector in use. Furthermore, because the first curved section 211 is provided at an angle toward the outer edge of the first opening 11, the contact area between the first conductive unit 2 and the electrical connector is reduced, i.e., the force-receiving area of ​​the electrical connector is reduced. During use, the pressure effect on the electrical connector becomes stronger, resulting in a stronger clamping of the electrical connector. When inserting the electrical connector, the force applied to the electrical connector is mitigated, the force applied to the electrical connector is distributed, and an appropriate insertion force is maintained, i.e., the electrical connector can be inserted more easily.

[0063] In this embodiment, as shown in Figure 9, the first conductive unit 2 further includes a strip-shaped elastic arm connecting member 26, and a plurality of second connection sections 242 are connected to the inner wall of the housing 1 via the elastic arm connecting member 26.

[0064] Multiple second connection sections 242 are connected to the inner wall of the housing 1 via elastic arm connecting members 26, thereby forming multiple second elastic arms 24 as a single unit. This improves the stability of the connection between each second elastic arm 24 and the housing 1.

[0065] In one embodiment of the present invention, as shown in Figures 7 and 9, the electrical connector further includes a second conductive unit 5 located between the first conductive unit 2 and the housing 1, and detachably connected to the first conductive unit 2. By providing the second conductive unit 5, the reliability of the mechanical contact and the electrical connection between the electrical connection device and the electrical connector is improved.

[0066] Furthermore, as shown in Figures 8 and 10, the second conductive unit 5 is provided with a first fixing member 6, and the first conductive unit 2 is provided with a first fixing fitting 7, and the first fixing member 6 can be locked and connected to the first fixing fitting 7.

[0067] This invention provides a first fixing member 6 and a first fixing fitting 7 that allows for quick attachment and detachment of the first conductive unit 2 and the second conductive unit 5, resulting in a simple structure and a strong connection.

[0068] In this application, as shown in Figure 10, the second conductive unit 5 includes a first elastic reinforcing portion 51 located in the first opening 11. The first elastic reinforcing portion 51 has a plurality of protrusions 511 that can penetrate the first gap 22 along the thickness direction H of the housing 1.

[0069] When two first conductive units 2 are provided within the housing 1, the multiple protrusions 511 of the first elastic reinforcing portion 51 can extend through the first gap 22 along the thickness direction H of the housing 1 to the space between the two first conductive units 2. Therefore, when an electrical connector is inserted into the housing 1 through the first opening 11 or the first insertion portion 13, the number of contact points of the electrical connector increases, further improving the connection strength with the electrical connector, that is, improving the reliability of the electrical connector's connection with the electrical connector in use. Furthermore, by providing the protrusions 511, the contact area between the first conductive unit 2 and the electrical connector is increased, the current transmission distance is shortened, and the temperature rise (also called the temperature threshold) and contact resistance are effectively reduced.

[0070] The materials used for the first conductive unit 2 and the second conductive unit 5 can be copper or a copper alloy, specifically, tellurium copper alloy, beryllium copper alloy, phosphor bronze alloy, lead brass alloy, or nickel copper alloy.

[0071] Tellurium copper alloys possess good conductivity and ease of cutting, ensuring electrical properties while also improving machinability.

[0072] Beryllium copper possesses high hardness, elastic limit, fatigue limit, and wear resistance, as well as good corrosion resistance, thermal conductivity, and electrical conductivity, and does not generate sparks when subjected to impact.

[0073] The advantages of phosphor bronze are its superior corrosion resistance and wear resistance, its ability to ensure good contact, its good elasticity, its excellent machinability, and its ability to rapidly reduce the processing time of parts.

[0074] The advantages of lead brass alloys are their high strength, dense and uniform structure, excellent corrosion resistance, and superior machining performance such as cutting and drilling. Nickel copper alloys have good corrosion resistance, high hardness, and good ductility, and can reduce the temperature coefficient of their electrical resistivity.

[0075] Furthermore, as shown in Figure 10, the first elastic reinforcing portion 51 further includes positive pressure portions 512 that can abut against a plurality of adjacent first curvature sections 211 along the thickness direction H of the housing 1, and the plurality of protrusions 511 are provided on the positive pressure portions 512 at intervals along the width direction Q of the housing 1.

[0076] By providing the positive pressure portion 512, a base can be provided for attaching each protrusion 511. Furthermore, since the positive pressure portion 512 can abut against a plurality of adjacent first curved sections 211 along the thickness direction H of the housing 1, when the electrical connection device is inserted into the housing 1 via the first opening 11, the first insertion portion 13, or the second insertion portion 14 and electrically connected to the first conductive unit 2, the electrical connection device has a certain thickness, which causes the first curved section 211 to move toward the inner wall of the adjacent housing 1 along the thickness direction H of the housing 1. By providing the positive pressure portion 512, positive pressure can be provided to the first curved section 211, making it less likely for the first curved section 211 of the first conductive unit 2 to bend and deform, and improving the clamping force from the first conductive unit 2 to the electrical connection device.

[0077] As shown in Figure 10, the second conductive unit 5 further includes a second elastic reinforcing portion 53 located in the second opening 12, the second elastic reinforcing portion 53 being connected to the first elastic reinforcing portion 51 via a second terminal body 52. ​​The second elastic reinforcing portion 53 has a plurality of reinforcing arms 531 that penetrate the second gap 25 along the thickness direction H of the housing 1.

[0078] When two first conductive units 2 are provided within the housing 1, the multiple reinforcing arms 531 of the second elastic reinforcing portion 53 can extend through the second gap 25 along the thickness direction H of the housing 1 to the space between the two first conductive units 2. Therefore, when an electrical connector is inserted between the two first conductive units 2 in the housing 1 through the second opening 12, the number of contact points of the electrical connector increases, further improving the connection strength with the electrical connector, that is, improving the reliability of the electrical connector connecting to the electrical connector in use. Furthermore, by providing multiple reinforcing arms 531 that extend through the second gap 25 along the thickness direction H of the housing 1 to the space between the two first conductive units 2, the contact area between the first conductive units 2 and the electrical connector is increased, the current transmission distance is shortened, and the temperature rise (also called the temperature threshold) and contact resistance are effectively reduced.

[0079] Furthermore, as shown in Figure 10, each reinforcing arm 531 includes abutment sections 5311 and contact sections 5312 that are sequentially connected from the first opening 11 to the second opening 12, with multiple abutment sections 5311 capable of contacting the second elastic arm along the thickness direction H of the housing 1, and the contact sections 5312 passing through the second gap 25 along the thickness direction H of the housing 1.

[0080] By providing the contact section 5311, positive pressure is provided to the second connection section 242. When the electrical connector is inserted into the housing 1 through the second opening 12 and electrically connected to the first conductive unit 2, the electrical connector has a certain thickness, causing the second connection section 242 to move along the thickness direction H of the housing 1 toward the inner wall of the adjacent housing 1. By providing the contact section 5311, positive pressure can be provided to the second connection section 242, making deformation such as bending less likely to occur in the second connection section 242 of the first conductive unit 2, and improving the clamping force from the first conductive unit 2 to the electrical connector. By providing the contact section 5312, the number of contact points with the electrical connector at the second opening 12 can be increased, further improving the connection strength with the electrical connector, that is, improving the reliability of the electrical connector connecting with the electrical connector in use, and further increasing the contact area with the electrical connector, shortening the current transmission distance, and effectively reducing the temperature rise value (also called the temperature threshold) and contact resistance value.
