Description

[Technical Field]

[0001] TECHNICAL FIELD The present disclosure relates to the field of electrical connectors, and more particularly to electrical connector assemblies. [Background technology]

[0002] With the development of various electronic devices, the applications of electrical connector assemblies are becoming increasingly widespread. Chinese Patent Publication CN113871945A discloses an electrical connector including a pin, a barrel, a coil spring, and an insulator. The barrel covers a portion of the pin, and the coil spring is positioned within the barrel and positioned between the pin and the bottom wall of the barrel, allowing the pin to move axially along the barrel. The pin is covered with an insulator, and the insulator and the outer wall surface of the pin are tightly fitted to seal the gap between the insulator and the pin. However, the insulator moves up and down with the pin, and in a vibration environment, it cannot continue to seal the gap between the pin and the first casing, which increases the risk of external water droplets penetrating into the electronic device. Furthermore, because the pin and barrel use impact-type contact, the contact resistance is high. Vibration can cause a problem of poor contact between the pin and the barrel, resulting in an instantaneous disconnection of the electrical connection. Therefore, further improvements are needed.

However, the exemplary embodiments may be implemented in various forms and should not be understood as being limited to the implementations described herein. On the contrary, providing these implementations will ensure that the present disclosure is comprehensive and complete, and will fully convey the concept of the exemplary implementations to those skilled in the art. Note that, since identical reference numerals in the figures indicate identical or similar configurations, repeated description thereof will be omitted. The term "or" in the description can also mean "and" or "or." Terms such as "up," "down," and "between" may be used in the description to describe different exemplary features and elements of the present disclosure; however, these terms are used herein for convenience only, for example, based on the exemplary orientations in the accompanying drawings. Nothing in this description should be understood as requiring a specific three-dimensional orientation of a structure to fall within the scope of the present disclosure. Although the terms "first" or "second" are used in this description to refer to particular features, they are intended for indication purposes only and do not serve as limitations on the number and importance of particular features.

[0025] The present disclosure provides an electrical connector assembly including an elastic waterproof member and at least one electrical connector mounted on the elastic waterproof member, the electrical connector including contact members, a support element, a conductive base, and an elastic drive member. The contact members are partially exposed on a first side of the elastic waterproof member along a first direction, and the contact members are integrated with the elastic waterproof member. Thus, in the present disclosure, an elastic waterproof member that can be attached to the outer casing of an electronic device is provided on the exterior of the electrical connector, whereby the elastic waterproof member is integrated with the contact members of the electrical connector and can undergo elastic deformation to accommodate movement of the contact members, effectively preventing water droplets from penetrating into the interior of the electronic device and the electrical connector through gaps between the contact members and the elastic waterproof member, thereby achieving a good waterproof effect.

[0026] The support element is provided on a second side of the elastic waterproofing member along a first direction, and the support element and the contact element are fixed to each other to establish an electrical connection. The conductive base includes at least one elastic contact arm, and the elastic contact arm and the support element are in slidable contact with each other to form the electrical connection. The elastic drive member is provided between the conductive base and the support element. The contact element and the support element can slide along the first direction relative to the conductive base by the elastic drive member. Therefore, the elastic contact arm of the conductive base and the support element are in elastic contact with each other, establishing a good electrical connection and preventing poor contact and momentary disconnection during vibration, effectively promoting the stability and reliability of the electrical connector assembly.

[0027] The structure of the electrical connector assembly of each specific embodiment will be described below with reference to the drawings. It should be understood that the drawings and the following description are merely exemplary and do not limit the scope of protection of the present disclosure. In the present disclosure, the first direction refers to the S1 direction of the viewing angle of FIG. 3, i.e., the up-down direction, and the width direction refers to the S2 direction of the viewing angle of FIG. 3, i.e., the left-right direction. In the viewing angle of FIG. 3, the width direction S2 is also the radial direction of the support posts of the contact members.

[0028] 1 to 9 show an electrical connector assembly according to a first embodiment of the present disclosure. As shown in FIGS. 1 to 4, the electrical connector assembly includes an outer casing 1 for an electronic device, an elastic waterproof member 2, a circuit board 4, and at least one electrical connector 3 attached to the elastic waterproof member 2. The elastic waterproof member 2 is fixed to the surface of the outer casing 1, and most of the electrical connector 3 is located inside the outer casing 1. The elastic waterproof member 2 includes a first side and a second side along a first direction. From the viewing angle of FIG. 3, the first side and the second side of the elastic waterproof member 2 correspond to the upper and lower sides of the elastic waterproof member 2, respectively. The electrical connector 3 includes a contact member 31, a support element 32, and a conductive base 34. The contact member 31 includes a dome-shaped contact portion 311 disposed on the first side and a support post 313 disposed on the second side, the support post 313 being preferably hollow. The upper portion of the contact portion 311 is exposed to the upper side of the elastic waterproof member 2. The support element 32 is provided on the underside of the elastic waterproof member 2, and the support element 32 and the contact member 31 are fixed together and electrically connected. The conductive base 34 includes at least one elastic contact arm 342 extending upward, and the elastic contact arm 342 and the support element 32 slidably contact each other to form an electrical connection. Although the elastic waterproof member 2 of the first embodiment is provided with three electrical connectors 3, the present disclosure is not limited thereto, and the number of electrical connectors 3 may be one, two, or more than three.

[0029] The contact member 31 is integrated with the elastic waterproof member 2 to form a sealing interface that prevents water and foreign objects from penetrating into the interior of the electrical connector 3 or the interior of the outer casing 1. Specifically, the contact member 31 and the elastic waterproof member 2 are engaged with each other through an insert molding process, a press-fitting process, or an adhesive process. For example, the contact member 31 is placed in a mold for the elastic waterproof member 2 in advance, and a molten plastic material is injected into the mold and cooled to obtain a part. That is, the contact member 31 is integrated with the elastic waterproof member 2. This method can achieve close cooperation between the contact member 31 and the elastic waterproof member 2. In another alternative implementation, the contact member 31 may be pressed onto the molded elastic waterproof member 2, or an adhesive may be applied between the outer periphery of the contact member 31 and the elastic waterproof member 2 to bond them to each other. After the contact member 31 and the elastic waterproof member 2 are engaged with each other, they may be assembled with the support element 32.

[0030] The elastic waterproof member 2 may be made of a material with a certain degree of elasticity, such as silica gel or plastic. By providing the elastic waterproof member 2 on the outside of the outer casing 1 of the electronic device, the elastic waterproof member 2 is integrated with the contact members 31 of the electrical connector 3, and the elastic waterproof member 2 can elastically deform to accommodate the movement of the contact members 31, effectively preventing water droplets from penetrating into the interior of the electronic device and the electrical connector 3 through the gap between the contact members 31 and the elastic waterproof member 2, thereby achieving a good waterproof effect. The elastic waterproof member 2 and the outer casing 1 may be press-fitted or glued together, which prevents water droplets from entering the interior of the electronic device and the electrical connector 3 through the gap between the elastic waterproof member 2 and the outer casing 1, further enhancing the waterproof effect of the electrical connector assembly.

[0031] 3 to 5 , a resilient driving member 33 is further provided between the support element 32 and the conductive base 34. The resilient driving member 33 is configured to provide an upward biasing force to the support element 32, thereby tightly pressing the contact element 31 against another mating element (not shown, which may be a conductive metal post) to achieve a conductive function. The resilient driving member 33 allows the contact element 31 and the support element 32 to move along a first direction relative to the conductive base 34. A first receiving groove 321 is provided on the upper side of the support element 32, and a second receiving groove 322 is provided on the lower side of the support element 32. The first receiving groove 321 is used to receive the post 313 of the contact element 31. The post 313 can form an interference fit with the first receiving groove 321 so that the post 313 is firmly fixed in the first receiving groove 321, and the lower side of the post 313 abuts against the bottom wall of the first receiving groove 321. The second receiving groove 322 is used to receive the elastic drive member 33. The elastic drive member 33 is a coil spring, but in other implementations, the elastic drive member 33 may be other elastic elements, such as a leaf spring or an elastic pad. As shown in FIG. 3 , the support element 32 is provided with a second step 323, and the outer casing 1 is provided with a limiting portion 11 facing the second step 323, the limiting portion 11 being located above the second step 323. The limiting portion 11 limits the upward stroke of the support element 32, preventing the support element 32 from detaching upward from the casing 1.

[0032] 3, the elastic waterproof member 2 includes a plurality of downwardly extending elastic extensions 21, which are located outside the electrical connector 3. The elastic extensions 21 are U-shaped and can elastically support the contact members 31 and provide a space for the contact members 31 to elastically move up and down.

[0033] As shown in FIGS. 5 to 9 , a receiving hole 41 is provided in the circuit board 4, and at least a portion of the conductive base 34 is positioned within the receiving hole 41. The conductive base 34 includes a base body 341, which is provided below the support element 32. A conical positioning portion 344 protruding upward is provided on the upper surface of the base body 341 at a position corresponding to the elastic drive member 33. The positioning portion 344 cooperates with the elastic drive member 33 to position it and maintain its positional stability. The elastic contact arm 342 is connected to the base body 341 and extends toward the support element 32 relative to the base body 341. The conductive base 34 further includes a connection leg 343, which extends toward the outside of the base body 341 and can be connected to the circuit board 4 by soldering. The base body 341 is electrically connected to the circuit board 4 via the connection leg 343. The conductive base 34 is integrally formed by stamping a metal sheet, achieving a stable and reliable electrical connection between the support element 32 and the circuit board 4. When combined with FIG. 3 , it can be seen that the width of the base body 341 is greater than the width of the support element 32 in the S2 direction, so that the contact positions of the resilient contact arms 342 bend inward relative to the connection positions of the resilient contact arms 342 and the base body 341. Here, "inward" refers to the direction toward the axis of the support element 32. Two resilient contact arms 342 are provided on two opposite sides of the base body 341. After being formed by bending, the two resilient contact arms 342 always tend to tighten inward. As a result, during use, the two resilient contact arms 342 can always surround the outer wall of the support element 32. As a result, the two resilient contact arms 342 always maintain electrical connection with the outer wall of the support element 32 and maintain stable contact effect even in a vibration environment.

[0034] FIG. 7 is a schematic diagram of the current direction when the electrical connector 3 is in use. In use, the contact portion 311 can form a contact-type electrical connection with another mating component. When the electrical connector 3 is used to input current from the outside, the current direction corresponds to the direction of the arrow in FIG. 7 . That is, the current from the outside is transmitted to the support element 32 via the contact portion 311 of the contact member 31, transmitted to the conductive base 34 via the contact point between the support element 32 and the elastic contact arm 342, and then transmitted to the circuit board 4 via the connection leg 343. When the electrical connector 3 is used to output current to the outside, the current direction is opposite to the direction of the arrow in FIG. 7 . When the electrical connector 3 is acted upon by a mating component, the contact portion 311 and the support element 32 move downward, compressing and elastically deforming the elastic drive member 33. The two resilient contact arms 342 of the conductive base 34 respectively clamp the two sides of the support element 32 and together resiliently contact the support element 32, establishing a good and stable electrical connection, preventing momentary disconnection during vibration, and effectively promoting the use stability and reliability of the electrical connector assembly. The resilient contact method between the two resilient contact arms 342 and the support element 32 used in the present disclosure is tighter, with smaller contact resistance, and the cooperation between the two resilient contact arms 342 and the support element 32 is more stable, making it better suited to high-current transmission scenarios.

[0035] 3 and 9 , the outer edge of the contact portion 311 expands outward to form a mounting portion 315, the outer diameter of which is larger than the outer diameters of the contact portion 311 and the support post 313, allowing the contact member 31 to form a tighter and more stable connection with the elastic waterproof member 2. A constricted portion 312, recessed inward, is further provided between the mounting portion 315 and the support post 313, and the elastic waterproof member 2 is partially filled around the constricted portion 312, further improving the connection strength between the elastic waterproof member 2 and the contact member 31 and achieving a better waterproof effect. The upper side of the support element 32 may abut against the elastic waterproof member 2 to further promote the sealing performance of the electrical connector 3.

[0036] 10 and 11 are partial schematic views of an electrical connector assembly according to a second embodiment of the present disclosure. The second embodiment differs from the first embodiment in the structure and cooperation between the contact member 31 and the support element 32. In the second embodiment, a first step 314 is further provided between the mounting portion 315 of the contact member 31 and the support post 313. The first step 314 presses against the upper edge of the support element 32, and the support element 32 functions to support and fix the contact member 31. A second gap 52 is formed in the first direction between the bottom of the support post 313 and the bottom surface of the first receiving groove 321. The second gap 52 can be secured to allow for assembly tolerances between the contact member 31 and the support element 32 and reduce the assembly accuracy requirements between the contact member 31 and the support element 32. In other embodiments not shown, the first step 314 may be formed as an inwardly recessed annular groove, and the elastic waterproof member 2 may extend further into the annular groove, thereby making the cooperation between the elastic waterproof member 2 and the contact member 31 more stable.

[0037] 12 and 13 are partial schematic views of an electrical connector assembly according to a third embodiment of the present disclosure. The third embodiment differs from the first embodiment in that a first step 314 is further provided between the mounting portion 315 of the contact member 31 and the support post 313. The first step 314 presses against the upper side of the support element 32, and the relative position between the contact member 31 and the support element 32 in the first direction is limited by the first step 314. At the same time, the first receiving groove 321 and the second receiving groove 322 communicate with each other to form a through hole that penetrates vertically. The support post 313 of the contact member 31 and the first receiving groove 321 form an interference fit therebetween. The struts 313 of the contact member 31 may be designed to be longer, so that the portion of the struts 313 that extends downward and enters the first receiving groove 321 is greater, thereby promoting the stability of cooperation between the contact member 31 and the support element 32 in the radial direction.

[0038] 14 to 16 are partial schematic views of an electrical connector assembly according to a fourth embodiment of the present disclosure. The fourth embodiment differs from the first embodiment in that a first step 314 is further provided between the mounting portion 315 of the contact member 31 and the support post 313, the first step 314 presses against the upper side of the support element 32, and the relative position between the contact member 31 and the support element 32 in the first direction is limited by the first step 314. The first receiving groove 321 of the support element 32 includes an opening 3211 with a large inner diameter and a receiving portion 3212 with a small inner diameter, the opening 3211 is located above the receiving portion 3212, and the receiving portion 3212 and the second receiving groove 322 are in communication with each other. The lower half of the first step portion 314 is positioned within the opening 3211 , and the first step portion 314 presses against the bottom surface of the opening 3211 , thereby firmly fixing the support post 313 to the receiving portion 3212 .

[0039] In the fourth embodiment, the inner wall of the opening 3211 and the first step 314 form a first gap 51 in the radial direction, and the lower part of the elastic waterproofing member 2 has the protrusion 22 located in the first gap 51. This increases the engagement length between the elastic waterproofing member 2 and the contact member 31 in the vertical direction, further enhancing the sealing effect of the elastic waterproofing member 2 on the electrical connector 3. A third gap is formed in the first direction between the bottom surface of the protrusion 22 and the bottom surface of the opening 3211, preventing the elastic waterproofing member 2 from interfering with the contact member 31 being fully inserted into the support element 32. In another alternative implementation form (not shown), the bottom surface of the protrusion 22 may be pressed against the bottom surface of the opening 3211 to enhance cooperation between the elastic waterproofing member 2 and the support element 32.

[0040] The above contents have further described the present disclosure in detail based on certain preferred embodiments, and the specific implementation aspects of the present disclosure should not be considered limited to these descriptions. Those skilled in the art to which the present application pertains can make some simple inferences or substitutions without departing from the concept of the present disclosure, and they should be considered within the scope of protection of the present disclosure.
