[0034] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0035] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0036] For ease of description, spatially relative relationship terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms such as "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "upper", "front", "rear", etc. This spatially relative relationship term is intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or attitude change or movement state change, then these directional indications will also change accordingly. For example, an element described as "below other elements or features" or "beneath other elements or features" will subsequently be oriented as "above other elements or features" or "on other elements or features". Therefore, the exemplary term "below" can include both the upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatially relative relationship descriptors used in the text are interpreted accordingly.

[0037] In order to solve the technical problem in the related art that due to the wear of the fixture and human factors, such as the fixture not being clamped in place, the pad may be warped, resulting in poor soldering and the product being unable to conduct electricity, the present application proposes a connector assembly. The conductive disk in the conductive terminal is connected to the flexible cable assembly by the bonding part, which can effectively conduct current, and the auxiliary conductive part can form a snap connection with the flexible cable assembly, reducing the technological processes such as fixing fixtures and spot welding, and making the connection more stable. And if the connection between the bonding part and one side of the conductive disk fails, the auxiliary conductive part contacts and connects with the flexible cable assembly, which can continue to ensure the conduction connection between the conductive terminal and the flexible cable assembly and avoid connection failure.

[0038] In some exemplary embodiments, as Figure 1 shown, a connector assembly 1 is installed in the headphone charging case to charge the headphones. The headphones are, for example, Bluetooth wireless headphones to meet the user's audio needs. The headphone charging case includes a body 2 and a charging compartment (not shown in the figure). The body 2 is disposed in the charging compartment, and the connector assembly 1 is disposed on the body 2. For example, two grooves are provided on the body 2 to facilitate placing the left headphone and the right headphone respectively. The number of connector assemblies 1 is the same as that of the headphones, so that the left headphone and the right headphone are respectively connected to the corresponding connector assemblies 1 to realize the electrical connection of the left headphone and the right headphone and complete signal transmission.

[0039] In this embodiment, as Figures 2 - 6 shown, the connector assembly 1 includes a conductive terminal 11, a flexible cable assembly 12, and a bonding part 13. The conductive terminal 11 is, for example, a probe made of a metal material and is in contact connection with the headphones to facilitate conduction.

[0040] The conductive terminal 11 includes a conductive body 111, a conductive disk 112, and an auxiliary conductive part 113. The conductive body 111 is, for example, a rod-shaped structure, which can be a cylindrical rod, a square rod, etc. The conductive disk 112 and the auxiliary conductive part 113 are sequentially arranged along the extension direction of the conductive body 111. The conductive disk 112 and the auxiliary conductive part 113 are respectively fixedly connected to the conductive body 111, for example, they can be integrally formed to improve the reliability during connection. The conductive disk 112 is sleeved on the conductive body 111. The conductive disk 112 is, for example, a plate-shaped structure to increase the contact area with the flexible cable assembly 12 and ensure the conduction between the conductive disk 112 and the flexible cable assembly 12.

[0041] The flexible cable assembly 12 is provided with a first through hole 1241. The flexible cable assembly 12 is a plate-shaped structure, which has a first surface 121 and a second surface 122. The conductive body 111 can pass through the first through hole 1241, so that the auxiliary conductive part 113 is in contact connection with the first surface 121 to complete conduction. Among them, the auxiliary conductive part 113 can be deformed to facilitate passing through the first through hole 1241 to complete the assembly connection.

[0042] Exemplarily, the auxiliary conductive part 113 includes a clamping elastic piece 1131. The clamping elastic piece 1131 has a connecting end 1132 and a free end 1133. The clamping elastic piece 1131 is fixedly connected to the conductive main body 111 through the connecting end 1132 to improve the reliability when the clamping elastic piece 1131 is connected. The free end 1133 is suspended so as to facilitate applying pressure to the free end 1133. By pressing the free end 1133, the deformation of the auxiliary conductive part 113 is realized.

[0043] The clamping elastic piece 1131 deforms under the force, so that the free end 1133 abuts against the outer side wall of the conductive main body 111, shrinking the overall volume of the auxiliary conductive part 113, so that the auxiliary conductive part 113 of the conductive terminal 11 can pass through the first through hole 1241.

[0044] When the clamping elastic piece 1131 is in the state of unloading force, the free end 1133 rebounds and resets, so that the free end 1133 retreats from the conductive main body 111, and the free end 1133 can contact and connect with the flexible cable assembly 12 to achieve conduction.

[0045] It should be noted that the above clamping elastic piece 1131 can be one, two or more. Two clamping elastic pieces 1131 can be symmetrically arranged on both sides of the conductive main body 111 to facilitate pressing the two clamping elastic pieces 1131. When multiple clamping elastic pieces 1131 are provided, they can be evenly arranged along the circumferential direction of the conductive main body 111, specifically subject to the actual situation.

[0046] The clamping elastic piece 1131 is, for example, a sheet-like structure. The connecting end 1132 is fixedly connected to the conductive main body 111, and the free end 1133 is upturned, so that the clamping elastic piece 1131 forms an umbrella-like shape on the conductive main body 111, realizing the effect that the clamping elastic piece 1131 can be deformed and is convenient for installation, or can be reset and rebound, facilitating the clamping connection with the flexible cable assembly 12. There is no need for auxiliary tools such as jigs in the related art to intervene, improving the assembly efficiency, simplifying the process flow, and ensuring that the clamping elastic piece 1131 can be in a conductive state with the flexible cable assembly 12.

[0047] A first protrusion 1134 is provided at the free end 1133 of the clamping elastic piece 1131. The first protrusion 1134 extends towards the direction of the conductive main body 111, so that the first protrusion 1134 can abut against the outer side wall of the conductive main body 111 to avoid excessive force application and affect the rebound of the clamping elastic piece 1131. At the same time, when the clamping elastic piece 1131 is released, its first protrusion 1134 is located at the edge of the free end 1133, forming a bent shape relative to the clamping elastic piece 1131, which can increase the contact area between the clamping elastic piece 1131 and the flexible cable assembly 12, ensuring that the clamping elastic piece 1131 can always be in a conductive state with the flexible cable assembly 12.

[0048] Wherein, a second protrusion 1111 may be provided on the outer side wall of the conductive body 111. The second protrusion 1111 is arranged corresponding to the first protrusion 1134, so that when the buckling elastic piece 1131 deforms under force, the second protrusion 1111 abuts against the corresponding first protrusion 1134. The second protrusion 1111 supports the first protrusion 1134, achieving anti-overstress and avoiding damage to the buckling elastic piece 1131.

[0049] It should be noted that the second protrusion 1111 may be one, arranged in a ring shape on the outer side wall of the conductive body 111, or may be multiple, corresponding to the first protrusion 1134 one by one, specifically subject to the actual situation.

[0050] In this embodiment, as Figures 2 - 6 shown, the conductive disk 112 is bonded to the second surface 122 through the bonding portion 13. The connection method is simple and reliable and easy to implement. And the orthographic projection of the bonding portion 13 on the flexible cable assembly 12 coincides with the orthographic projection of the conductive disk 112 on the flexible cable assembly 12, so that the bonding portion 13 can cover the entire conductive disk 112, ensuring an effective connection between the conductive disk 112 and the flexible cable assembly 12 and avoiding loosening or poor contact, etc. Among them, the bonding portion 13 is provided with an avoidance through hole 131, for example, to avoid the conductive body 111.

[0051] The bonding portion 13 includes a conductive adhesive layer, for example. The conductive adhesive layer is a pressure sensitive adhesive (PSA) for short, so that the bonding portion 13 has a strong bonding force and can firmly bond the conductive disk 112 and the flexible cable assembly 12 together. And the conductive adhesive layer also has conductivity and can effectively conduct current, meeting the electrical connection requirements between the flexible cable assembly 12 and the conductive disk 112. It adapts to different shapes and sizes, maintains good electrical conductivity, and effectively avoids the high-temperature damage and environmental pollution problems that may be brought by the welding method in the related art.

[0052] In this embodiment, as Figures 2 - 6 shown, the flexible cable assembly 12 includes a flexible cable 123 and a connecting ring body 124. The flexible cable 123 is provided with a second through hole 1231, and the connecting ring body 124 is embedded in the second through hole 1231. The flexible cable 123 is buckled on the circuit board to form an electrical connection.

[0053] Among them, the buckling elastic piece 1131 of the auxiliary conductive portion 113 is in contact connection with the connecting ring body 124, the bonding portion 13 is connected to the connecting ring body 124, and the ring hole of the connecting ring body 124 is configured as a first through hole 1241, so as to facilitate the auxiliary conductive portion 113 to pass through the flexible cable assembly 12.

[0054] The orthographic projection of the connecting ring body 124 on the conductive disk 112 coincides with the orthographic projection of the bonding portion 13 on the conductive disk 112, so that the bonding portion 13 can cover the entire connecting ring body 124, ensuring an effective connection between the conductive disk 112 and the connecting ring body 124 and avoiding looseness or poor contact, etc. Among them, the connecting ring body 124 is, for example, a metal ring, making it conductive and capable of effectively conducting current to meet the electrical connection requirements between the flexible cable assembly 12 and the conductive disk 112.

[0055] This application also provides a headset charging case, including a main body and a connector assembly as in the above embodiments, and the connector assembly is installed in the main body. The main body includes, for example, an inner shell and an outer shell. The inner shell is disposed inside the outer shell, and a groove is provided in the inner shell. The headset charging case includes a headset and an electrical connection assembly. The headset is electrically connected to the connector assembly through the electrical connection assembly to achieve conduction for charging the headset. The headset can be placed in the groove to form a restraint on the headset and facilitate contact connection with the electrical connection assembly. The electrical connection assembly can include, for example, a plurality of conductive elements, etc., to facilitate the implementation of corresponding functions, which shall be subject to the actual situation.

[0056] The conductive terminal in the connector assembly is a probe (pin) for contact connection with the headset. The conductive disk in the conductive terminal is connected to the connecting ring body in the flexible cable assembly by using the bonding portion, effectively conducting current and solving the technical problems of poor contact and complex process flow of the intervening fixture in the related art.

[0057] The auxiliary conductive portion in the conductive terminal can be deformed to pass through the first through hole and can form a snap connection with the flexible cable assembly when released, reducing process flows such as fixing fixtures and spot welding, and the connection is more stable. And if the connection on one side of the bonding portion and the conductive disk fails, the auxiliary conductive portion contacts and connects with the connecting ring body in the flexible cable assembly, which can continue to ensure the conduction connection between the conductive terminal and the flexible cable assembly and avoid connection failure.
