Description

Technical Field

[0001] The present application relates to the technical field of electrical connectors, and in particular to an electrical connector assembly. Background Art

[0056] The present application provides an electrical connector combination, including an elastic waterproof member and at least one electrical connector arranged on the elastic waterproof member, wherein the electrical connector includes a contact element, a supporting member, a conductive base and an elastic driving member. Part of the contact element is exposed to the first side of the elastic waterproof member along the first direction, and the contact element is integrated with the elastic waterproof member. Therefore, the present application provides an elastic waterproof member that can be assembled on the housing of an electronic device on the outside of the electrical connector, the elastic waterproof member is integrated with the contact element of the electrical connector, and the elastic waterproof member can be elastically deformed to adapt to the movement of the contact element, thereby effectively preventing water droplets from penetrating into the interior of the electronic device and the electrical connector from the gap between the contact element and the elastic waterproof member, thereby achieving a good waterproof effect.

[0057] The supporting element is arranged on the second side of the elastic waterproof element along the first direction, and the supporting element is fixed together with the contact element and establishes an electrical connection. The conductive base includes at least one elastic contact arm, and the elastic contact arm is in sliding contact with the supporting element to form an electrical connection. The elastic driving member is arranged between the conductive base and the supporting element. The contact element and the supporting element can slide relative to the conductive base along the first direction through the elastic driving member. Therefore, the elastic contact arm of the conductive base is in elastic contact with the supporting element, and a good electrical connection can be established, which prevents momentary disconnection caused by poor contact during vibration, and effectively improves the stability and reliability of the use of the electrical connector combination.

[0058] The structure of the electrical connector assembly in various specific embodiments is described below in conjunction with the accompanying drawings. It is understandable that the accompanying drawings and the following description are only examples and are not intended to limit the scope of protection of this application. In this application, the first direction refers to Figure 3 The S1 direction in the viewing angle refers to the up-down direction, and the width direction refers to Figure 3 The S2 direction in the viewing angle, that is, the left and right direction, is Figure 3 From the perspective of , the width direction S2 is also the radial direction of the column of the contact element.

[0059] Figures 1 to 9 The electrical connector assembly of the first embodiment of the present application is shown. Figures 1 to 4 As shown, the electrical connector assembly includes a housing 1 of an electronic device, an elastic waterproof member 2, a circuit board 4, and at least one electrical connector 3 provided on the elastic waterproof member 2. The elastic waterproof member 2 is fixed to the surface of the housing 1, and most of the electrical connector 3 is located inside the housing 1. The elastic waterproof member 2 includes a first side and a second side along a first direction, Figure 3 From the perspective of , the first side and the second side of the elastic waterproof member 2 correspond to its upper side and lower side respectively. The electrical connector 3 includes a contact element 31, a support element 32 and a conductive base 34. The contact element 31 includes a dome-shaped contact portion 311 located on the first side and a column 313 located on the second side, and the column 313 is preferably a hollow column 313. The upper part of the contact portion 311 is exposed to the upper side of the elastic waterproof member 2. The support element 32 is arranged on the lower side of the elastic waterproof member 2, and the support element 32 is fixed together with the contact element 31 and establishes an electrical connection. The conductive base 34 includes at least one elastic contact arm 342 extending upward, and the elastic contact arm 342 is in sliding contact with the support element 32 to form an electrical connection. Three electrical connectors 3 are provided on the elastic waterproof member 2 in this embodiment, but the present application is not limited thereto, and the number of the electrical connectors 3 can also be one, two or more.

[0060] The contact element 31 is integrated with the elastic waterproof part 2 to form a sealed interface that blocks water and prevents external foreign matter from entering the electrical connector 3 or the housing 1. Specifically, the contact element 31 is combined with the elastic waterproof part 2 through an insert molding process, a crimping process or a bonding process. For example, the contact element 31 is pre-placed in a molding mold of the elastic waterproof part 2, molten plastic material is injected into the molding mold, and the component obtained by cooling and molding is an integrated contact element 31 and elastic waterproof part 2. This method can achieve a close fit between the contact element 31 and the elastic waterproof part 2. In other alternative embodiments, the contact element 31 can also be pressed into the molded elastic waterproof part 2, or glue can be applied between the periphery of the contact element 31 and the elastic waterproof part 2 to bond the two together. After the contact element 31 is combined with the elastic waterproof part 2, it can be assembled with the support element 32.

[0061] The elastic waterproof member 2 can be made of materials such as silicone and plastic with a certain elasticity. By arranging the elastic waterproof member 2 on the outside of the housing 1 of the electronic device, the elastic waterproof member 2 is integrated with the contact element 31 of the electrical connector 3, and the elastic waterproof member 2 can be elastically deformed to adapt to the movement of the contact element 31, effectively preventing water droplets from penetrating into the interior of the electronic device and the electrical connector 3 from the gap between the contact element 31 and the elastic waterproof member 2, and achieving a good waterproof effect. The elastic waterproof member 2 and the housing 1 can be crimped or bonded together, so as to prevent water droplets from entering from the gap between the elastic waterproof member 2 and the housing 1, further improving the waterproof effect of the electrical connector combination.

[0062] like Figures 3 to 5 As shown, an elastic driving member 33 is further arranged between the support element 32 and the conductive base 34. The elastic driving member 33 is configured to provide an upward biasing force to the support element 32, so that the contact element 31 and another docking element (not shown in the figure, which can be a conductive metal column) are more tightly pressed together to achieve the conductive function. The contact element 31 and the support element 32 can move along the first direction relative to the conductive base 34 through the elastic driving member 33. A first receiving groove 321 is arranged on the upper side of the support element 32, and a second receiving groove 322 is arranged on the lower side. The first receiving groove 321 is used to accommodate the column 313 of the contact element 31. The column 313 can form an interference fit with the first receiving groove 321 to be fastened therein, and the lower side of the column 313 abuts against the bottom wall of the first receiving groove 321. The second receiving groove 322 is used to accommodate the elastic driving member 33. The elastic driving member 33 is a spring. In other embodiments, the elastic driving member 33 may also be other elastic components, such as a spring sheet, an elastic pad, etc. Figure 3As shown, the support element 32 is provided with a second step portion 323, and the housing 1 is provided with a limiting portion 11 opposite to the second step portion 323, and the limiting portion 11 is located above the second step portion 323. The limiting portion 11 can limit the upward movement of the support element 32 to prevent it from falling out upward.

[0063] like Figure 3 As shown, the elastic waterproof member 2 includes a plurality of elastic extensions 21 extending downward, and the elastic extensions 21 are located outside the electrical connector 3. The elastic extensions 21 are formed in a U shape, which can play an elastic supporting role for the contact element 31, and provide a space for the contact element 31 to move elastically up and down.

[0064] like Figures 5 to 9 As shown, the circuit board 4 is provided with a receiving hole 41, and at least a part of the conductive base 34 is located in the receiving hole 41. The conductive base 34 includes a base body 341, and the base body 341 is provided on the lower side of the supporting element 32. The upper surface of the base body 341 is provided with a positioning portion 344 protruding upward in a conical shape at a position corresponding to the elastic driving member 33. The positioning portion 344 cooperates with the elastic driving member 33 to maintain the position stability of the elastic driving member 33. The elastic contact arm 342 is connected to the base body 341, and is bent and extended relative to the base body 341 toward the supporting element 32. The conductive base 34 also includes a connecting pin 343, and the connecting pin 343 is bent and extended outward relative to the base body 341, and can be connected to the circuit board 4 by welding. The base body 341 is electrically connected to the circuit board 4 through the connecting pin 343. The conductive base 34 is integrally formed by stamping a metal sheet, so as to achieve a stable and reliable electrical connection between the supporting element 32 and the circuit board 4. Figure 3 It can be seen that in the S2 direction, the width of the base body 341 is greater than the width of the support element 32, so that the contact position of the elastic contact arm 342 is bent inward relative to the connection position between the elastic contact arm 342 and the base body 341. The inward here refers to the direction pointing to the axis of the support element 32. Two elastic contact arms 342 are provided on two opposite sides of the base body 341. After being bent and formed, the two elastic contact arms 342 always have a tendency to clamp inward, so that during use, the elastic contact arm 342 can always hold the outer wall of the support element 32, thereby always maintaining an electrical connection with the outer wall of the support element 32, and can maintain a stable contact effect in a vibration environment.

[0065] Figure 7Schematic diagram of the current direction when the electrical connector 3 is used. When in use, the contact portion 311 can form a contact-type electrical connection with another docking element. When the electrical connector 3 is used to input current from the outside, the current direction is the same as Figure 7 The direction of the arrow in the figure is consistent, that is, the external current is transmitted to the supporting element 32 through the contact portion 311 of the contact element 31, transmitted to the conductive base 34 through the contact point between the supporting element 32 and the elastic contact arm 342, and then transmitted to the circuit board 4 through the connecting pin 343. When the electrical connector 3 is used to output current to the outside, the current direction is consistent with Figure 7 The direction of the middle arrow is opposite. When affected by the docking element, the contact portion 311 and the support element 32 move downward, pressing the elastic drive member 33 to undergo elastic deformation. The two elastic contact arms 342 of the conductive base 34 are respectively clamped on both sides of the support element 32 and elastically contacted with the support element 32, which can establish a good and stable electrical connection, prevent momentary disconnection during vibration, and effectively improve the stability and reliability of the use of the electrical connector combination. The elastic contact method adopted in the present application is relatively close to the support element 32, the contact resistance is relatively small, and the cooperation between the two is relatively stable, which can be better applied to the scenario of large current transmission.

[0066] like Figure 3 and Fig. 9 As shown, the outer edge of the contact portion 311 expands outward to form a mounting portion 315. The outer diameter of the mounting portion 315 is larger than the outer diameter of the contact portion 311 and the outer diameter of the column 313, so that a tighter and more stable connection can be formed with the elastic waterproof member 2. A neck 312 recessed inward is also provided between the mounting portion 315 and the column 313. The elastic waterproof member 2 partially fills the outer periphery of the neck 312, so as to further improve the tightness of the connection between the elastic waterproof member 2 and the contact element 31 and have a better waterproof effect. The upper side of the support element 32 can abut against the elastic waterproof member 2 to further improve the sealing of the electrical connector 3.

[0067] Fig.10 and Fig.11It is a partial schematic diagram of the electrical connector assembly of the second embodiment of the present application. The difference between the second embodiment and the first embodiment is that the structure and matching mode of the contact element 31 and the support element 32 are different. In the second embodiment, a first step portion 314 is further provided between the mounting portion 315 of the contact element 31 and the column 313, and the first step portion 314 is abutted against the upper edge of the support element 32, and the support element 32 plays a supporting and fixing role for the contact element 31. A second gap 52 is formed between the bottom of the column 313 and the bottom surface of the first accommodating groove 321 in the first direction, and the second gap 52 can be reserved to allow the assembly tolerance between the contact element 31 and the support element 32, thereby reducing the assembly accuracy requirements for the contact element 31 and the support element 32. In other embodiments not shown, the first step portion 314 can also be set as a groove that is concave inward along an annular shape, and the elastic waterproof member 2 can further enter this annular groove, so that the matching between the elastic waterproof member 2 and the contact element 31 is more stable.

[0068] Fig.12 and Fig.13 This is a partial schematic diagram of the electrical connector assembly of the third embodiment of the present application. The difference between this embodiment and the first embodiment is that in the third embodiment, a first step portion 314 is further provided between the mounting portion 315 and the column 313 of the contact element 31, the first step portion 314 abuts against the upper side of the support element 32, and the first step portion 314 defines the relative position of the contact element 31 and the support element 32 in the first direction. At the same time, the first receiving groove 321 is connected with the second receiving groove 322 to form a through hole that passes through from top to bottom. An interference fit is formed between the column 313 of the contact element 31 and the first receiving groove 321. The column 313 of the contact element 31 can be designed to be longer, with more parts extending downward into the first receiving groove 321, thereby improving the stability of the radial fit between the contact element 31 and the support element 32.

[0069] Figures 14 to 16This is a partial schematic diagram of the electrical connector assembly of the fourth embodiment of the present application. The difference between this embodiment and the first embodiment is that in the fourth embodiment, a first step portion 314 is further provided between the mounting portion 315 of the contact element 31 and the column 313, the first step portion 314 abuts against the upper side of the support element 32, and the first step portion 314 defines the relative position of the contact element 31 and the support element 32 in the first direction. The first receiving groove 321 of the support element 32 includes an opening section 3211 with a larger diameter and a receiving section 3212 with a smaller diameter, the opening section 3211 is located on the upper side of the receiving section 3212, and the receiving section 3212 is connected to the second receiving groove 322. The lower half of the first step portion 314 is located in the opening section 3211, and the first step portion 314 abuts against the bottom surface of the opening section 3211, and the column 313 is fastened to the receiving section 3212.

[0070] In the fourth embodiment, the inner wall of the opening section 3211 and the first step portion 314 form a first gap 51 in the radial direction, and the lower part of the elastic waterproof member 2 has a protruding portion 22 located in the first gap 51, so that the elastic waterproof member 2 and the contact element 31 have a longer combination length in the vertical direction, further improving the sealing effect of the elastic waterproof member 2 on the electrical connector 3. A third gap is formed between the bottom surface of the protruding portion 22 and the bottom surface of the opening section 3211 in the first direction to prevent the elastic waterproof member 2 from blocking the contact element 31 from being fully inserted into the support element 32. In another alternative embodiment not shown, the bottom surface of the protruding portion 22 can also abut against the bottom surface of the opening section 3211 to improve the fit between the elastic waterproof member 2 and the support element 32.

[0071] The above content is a further detailed description of the present application in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
