Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the scope of the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

Along with the development of the diversification of the functions of the electronic equipment, the electronic equipment has various types and brands, so that consumers can select a plurality of electronic equipment, how to obtain the favor of the consumers becomes a problem that electronic equipment manufacturers pay more and more attention.

At present, in order to reduce the manufacturing difficulty and improve the assembly efficiency, the electronic device uses the electrical connection device to realize the connection between different electrical components (such as between different circuit boards or between a circuit board and different electronic devices).

However, in the related art, the electronic device needs to be additionally provided with a locking structure to prevent the electrical connection device from being loosened, which may result in poor contact between the electrical components, but this may result in low assembly efficiency of the electronic device. For example, at least two anti-loose structures such as screws are used for fixing the board-to-board electrical connection device so as to avoid poor contact between electrical elements, but the screws need to be rotated for many times to be tightened, so that the assembly efficiency of the electronic equipment is low; meanwhile, the arrangement of the anti-loose structures such as the screws can occupy the internal space of the electronic equipment, and the miniaturization development of the electronic equipment is not facilitated.

Based on this, this application embodiment provides an electric connection device, and this electric connection device connects reliably difficult emergence and becomes flexible for electronic equipment need not additionally to set up anti loosening structure, can be favorable to improving electronic equipment's packaging efficiency at least.

For a better understanding of the electrical connection device of the present invention, reference is made to the following description taken in conjunction with the accompanying drawings. As shown in fig. 1 to 3, the electronic device and the electrical connection device thereof shown in some embodiments are illustrated in a structural diagram. Fig. 1 is a schematic structural diagram of an electronic device shown in an embodiment. Fig. 2 is a schematic structural diagram of the electrical connection device shown in fig. 1. Fig. 3 is an exploded view of the electrical connection device shown in fig. 2.

As shown in fig. 1, in some embodiments, an electronic device 10 is provided, where the electronic device 10 may be a wearable device such as a bracelet or a watch, and the electronic device 10 includes a device body 100 and an electrical connection device 200, and the electrical connection device 200 is disposed on the device body 100.

As shown in fig. 2 to 3, the electrical connection device 200 includes a first connector 210, a second connector 220 and a locking member 230, wherein the first connector 210 includes a first insulating member 211 and a plurality of first conductive terminals 212 disposed on the first insulating member 211; the second connector 220 is detachably connected to the first connector 210, and the second connector 220 includes a second insulating member 221 and a plurality of second conductive terminals 222 disposed on the second insulating member 221; the locking member 230 is disposed on one of the first connector 210 and the second connector 220, the locking member 230 has a locked state and an unlocked state, and the locking member 230 can be switched between the locked state and the unlocked state; when the locking member 230 is in the locking state, the first connector 210 and the second connector 220 are locked, and the first conductive terminal 212 is electrically contacted with the second conductive terminal 222; when the locking member 230 is in the unlocked state, the first connector 210 is separable from the second connector 220.

It should be noted that, when the second connector 220 is connected to the first connector 210, the first conductive terminal 212 is electrically contacted with the second conductive terminal 222; when the first connector 210 and the second connector 220 are locked by the locking member 230, the first conductive terminal 212 and the second conductive terminal 222 are electrically contacted more reliably, and the stability of the connection between the two terminals is ensured by the locking member.

Thus, when the electronic device 10 is assembled, the electrical connection device 200 is disposed on the device body 100, and one of the first connector 210 and the second connector 220 is fixedly connected to the device body 100 and then connected to the other, and the locking member 230 is used to lock the first connector 210 and the second connector 220, so that the first conductive terminal 212 and the second conductive terminal 222 are electrically and reliably contacted. When the electronic device 10 is affected by external forces such as vibration, the first connector 210 and the second connector 220 are locked by the locking member 230, so that the first connector 210 and the second connector 220 are prevented from being separated easily and loosened, which is beneficial to ensuring reliable electrical contact between the first conductive terminal 212 and the second conductive terminal 222. In the electronic device 10, the first connector 210 and the second connector 220 are reliably connected, and no additional anti-loose structure is needed, which is beneficial to improving the assembly efficiency of the electronic device 10 and saving the cost; in addition, the locking member is disposed by fully utilizing the internal space of the electrical connection device 200, which is compact, and is beneficial to saving the internal space of the electronic device 10 and the miniaturization development of the electronic device 10.

When the locking member 230 is in the unlocked state, the first connector 210 and the second connector 220 are separable, so that the first connector 210 and the second connector 220 are convenient to disassemble and assemble, and the later maintenance of the electronic device 10 is convenient.

It should be noted that one of the first connector 210 and the second connector 220 is a female connector, and the other is a male connector. The first connector 210 and the second connector 220 can be respectively mounted on the corresponding circuit board 110 or electronic device, so as to achieve detachable electrical connection between different electrical components, facilitate modular assembly, improve assembly efficiency, and facilitate reduction of design and manufacturing difficulties of internal electrical components of the electronic device 10.

In addition, the specific implementation manners of the "first conductive terminal 212" and the "second conductive terminal 222" may be various, including but not limited to sheet metal parts, die castings, electroplating parts, and the like.

As shown in fig. 3, in some embodiments, locking element 230 is provided with a locking tongue 234; one of the first connector 210 and the second connector 220 without the locking member 230 is provided with a locking portion 224; when the locking member 230 is in the locked state, at least a portion of the tongue portion 231 can be inserted into the locking portion 224; when the locking member 230 is in the unlocked state, the locking tongue portion 231 is separated from the locking portion 224. Thus, the locking piece 230 is switched between the locking state and the unlocking state by the engagement or disengagement of the locking tongue 234 and the locking portion 224, which is easy to implement and beneficial to reducing the implementation cost.

The "locking portion 224" includes a hole, a groove, a recess, and the like that can be locked and engaged with the locking tongue portion 231.

In some embodiments, the locking portion is a hole, groove or recess into which the tongue portion is inserted when the locking member is in the locked state. In this manner, the hole, groove or recess is engaged with the latch tongue portion 231 to easily perform the locking function of the locking member 230, and the locking is reliable. When the locking member 230 needs to be unlocked, the locking tongue 231 is only required to be moved out of the hole, the groove or the pit, so that the locking member 230 can be in the unlocked state, and the operation is simple.

In some embodiments, the locking member further includes a reset member 240, and the locking member is automatically reset to the locking state by the reset member 240 when not subjected to an external force. When the second connector 220 and the first connector 210 are connected to a predetermined position, the locking member 230 can be automatically reset to a locking state, and at least part of the locking tongue 231 can be inserted into the locking part 224 to lock the second connector 220 on the first connector 210, so that the operation is simple, and the assembly efficiency of the first connector 210 and the second connector 220 can be improved.

The automatic reset of the locking member 230 may include a resilient reset or a magnetically attracted reset.

In a preferred embodiment, the locking member 230 is automatically reset to the first connector 210, and the second connector 220 is provided with a locking portion 224. Thus, when the second connector 220 is connected to the first connector 210, and the locking member 230 can be automatically reset to the locking state, at least a portion of the latch 231 can be inserted into the locking portion 224 to lock the second connector 220 to the first connector 210, so that the first conductive terminal 212 and the second conductive terminal 222 are reliably electrically contacted; when the first connector 210 and the second connector 220 need to be separated, the locking member 230 is only required to be moved reversely to the unlocking state, so that the locking portion 231 is separated from the locking portion 224, and the second connector 220 is detachably separated from the first connector 210.

In another preferred embodiment, the locking member 230 is automatically reset to the second connector 220, and the first connector 210 is provided with the locking portion 224. Thus, when the first connector 210 is connected to the second connector 220, and the locking member 230 can be automatically reset to the locking state, at least a portion of the latch 231 can be inserted into the latching portion 224 to lock the first connector 210 to the second connector 220, so that the first conductive terminal 212 and the second conductive terminal 222 are reliably electrically contacted; when the first connector 210 and the second connector 220 need to be separated, the locking member 230 is moved reversely to separate the locking portion 231 from the locking portion 224, so that the first connector 210 can be detached from the second connector 220.

As shown in fig. 3, based on any of the foregoing embodiments, in some embodiments, the first connector 210 is a female connector, the first insulating member has receiving grooves 2111, and at least a portion of the first conductive terminals 212 is disposed in the receiving grooves 2111, the second connector 220 is a male connector, at least a portion of the second connector 220 can be embedded in the receiving grooves 2111, so that the first conductive terminals 212 electrically contact with the second conductive terminals 222, and the locking member 230 is telescopically disposed in the first connector 210 through the resetting member 240; when the locking member 230 is in the locking state, at least a part of the locking member 230 protrudes from the receiving groove 2111, i.e. extends into the receiving groove 21111, and is engaged with the second connector 220 to achieve locking; when the locking member 230 is in the unlocked state, the locking member 230 is retracted from the receiving groove 2111 and separated from the second connector 220, and unlocking is achieved. Thus, the first connector 210 and the second connector 220 are nested through the receiving groove 2111, and when the locking member 230 is in the locking state, at least a portion of the locking member 230 protrudes from the receiving groove 2111, i.e. extends into the receiving groove 21111, and locks the second connector 220 disposed in the receiving groove 2111, so as to lock the second connector 220 to the first connector 210, and thus the first conductive terminal 212 and the second conductive terminal 222 are electrically contacted reliably; when the first connector 210 and the second connector 220 need to be detached, the locking member 230 only needs to be moved reversely to the unlocking state, so that the locking member 230 is separated from the second connector 220, and the second connector 220 is further separated from the first connector 210.

With such an arrangement, the receiving grooves 2111 are used to realize the nesting and fitting of the first connector 210 and the second connector 220, and the locking member 230 is used to lock the second connector 220, so as to reliably connect the first connector 210 and the second connector 220 together, which is not easy to loosen, and ensure reliable electrical contact between the first conductive terminals 212 and the second conductive terminals 222.

As shown in fig. 3 to 9, in some embodiments, the locking element 230 is elastically and telescopically disposed on the first connector 210, the locking element 230 is provided with a locking tongue 231 which can extend into the receiving groove 2111, and the second connector 220 is provided with a locking buckle 224; during the process of inserting the second connector 220 into the receiving groove 2111, the second connector 220 can press the locking member 230, so that the locking member 230 moves toward the unlocking state; when the second connector 220 contacts with the bottom of the receiving groove 2111, the locking member 230 can automatically return to the locking state, and the locking tongue portion 231 is inserted into the locking engagement with the locking portion 224. Thus, the locking member 230 can be elastically restored to the first connector 210, and when the first connector 210 is connected to the second connector 220, the second connector 220 can press the locking member 230 to make the locking member 230 shrink to the unlocked state, so that the second connector 220 can be inserted into the bottom of the receiving groove 2111; when the second connector 220 is embedded into the bottom of the receiving slot 2111, it indicates that the first connector 210 and the second connector 220 are installed in place, and the electrical connection requirement between the two is satisfied, at this time, when the locking element 230 can be elastically reset to the locking state, at least a part of the locking tongue 231 can be inserted into the locking part 224, and the second connector 220 is locked on the first connector 210, so that the electrical contact between the first conductive terminal 212 and the second conductive terminal 222 is more stable and reliable, and the assembly is convenient and rapid; when the first connector 210 and the second connector 220 need to be disassembled, the locking member 230 is only required to be moved reversely, so that the locking tongue portion 231 is separated from the locking portion 224, and the second connector 220 can be detached from the first connector 210, thereby facilitating maintenance, such as repair or screen replacement.

Further, the fitting of the locking tongue portion 231 with the locking portion 224 facilitates the locking function of the locking member 230 while utilizing the nesting fitting of the first connector 210 with the second connector 220, and the locking is reliable.

In addition to any of the above embodiments, in some embodiments, at least one of the locking tongue portion 231 and the locking portion 224 is provided with a guiding portion, and the guiding portion guides the locking member 230 to the unlocking state when the first connector 210 is connected to the second connector 220. Thus, in the process of connecting the second connector 220 and the first connector 210 to each other, the force for pressing the locking member 230 is converted into a force for pushing the locking member 230 to move to the unlocking state through the guiding portion, so that the locking member 230 overcomes the elastic restoring force (in other embodiments, the restoring force may also be magnetically attracted), and moves from the locking state to the unlocking state. When the first connector 210 and the second connector 220 are mounted at the predetermined positions, the electrical connection requirements of the first connector 210 and the second connector 220 are satisfied, and at this time, when the locking member 230 can be elastically restored to the locking state, at least part of the locking tongue 231 can be inserted into the locking part 224 to lock the second connector 220 on the first connector 210, so that the first conductive terminal 212 and the second conductive terminal 222 are electrically reliably contacted, and the assembly is convenient and rapid.

It should be noted that the specific implementation manner of the "guiding portion" may be various, and includes a rounded corner structure, an inverted corner structure, a guiding inclined surface 2311, a guiding arc surface 225, or the like.

The function of the guide portion can be further understood in conjunction with the aforementioned accommodation groove 2111. Specifically, the force of pressing the locking member 230 during the process of inserting the second connector 220 into the receiving slot 2111 is converted into a force pushing the locking member 230 to move to the unlocked state, so that the locking member 230 overcomes the elastic restoring force (in other embodiments, the restoring force may also be magnetically attracted), and the self-locking state moves to the unlocked state, thereby facilitating the second connector 220 to be smoothly inserted into the bottom of the receiving slot 2111. When the second connector 220 is inserted into the bottom of the receiving slot 2111, it indicates that the first connector 210 and the second connector 220 are mounted in place, and the electrical connection requirement between the first connector 210 and the second connector 220 is satisfied, and at this time, when the locking element 230 can be elastically restored to the locking state, at least a part of the tongue-locking portion 231 can be inserted into the locking portion 224, and the second connector 220 is locked on the first connector 210, so that the first conductive terminal 212 and the second conductive terminal 222 are electrically contacted reliably, and the assembly is convenient and fast.

As shown in fig. 3, 4, 5 and 9, in some embodiments, the locking tongue 231 is disposed on the first connector 210, the guiding portion includes a guiding inclined surface 2311 disposed on the locking tongue 231, and the second connector 220 can abut against the guiding inclined surface 2311 during the connection process between the first connector 210 and the second connector 220, so that the locking member 230 moves toward the unlocking state. Thus, in the process of connecting the second connector 220 and the first connector 210 to each other, the force pressing the locking member 230 is converted into a force pushing the locking member 230 to move to the unlocking state through the guiding inclined surface 2311, so that the locking member 230 overcomes the elastic restoring force (in other embodiments, the magnetic restoring force may also be used), and the self-locking state moves to the unlocking state. When the first connector 210 and the second connector 220 are mounted at the predetermined positions, the electrical connection requirements of the first connector 210 and the second connector 220 are satisfied, and at this time, when the locking member 230 can be elastically restored to the locking state, at least part of the locking tongue 231 can be inserted into the locking part 224 to lock the second connector 220 on the first connector 210, so that the first conductive terminal 212 and the second conductive terminal 222 are electrically reliably contacted, and the assembly is convenient and rapid.

Alternatively, as shown in fig. 5, in some embodiments, the guide slope 2311 is inclined from the outer edge of the receiving groove 2111 toward the bottom of the receiving groove 2111, that is, the guide slope 2311 is set from top to bottom in the moving direction (the locked state and the unlocked state switching) of the locking member 230; in the process of the second connector 220 being inserted into the receiving groove 2111, the second connector 220 can abut against the guide slope 2311 to move the locking member 230 in the direction of the unlocked state. Thus, in the process of inserting the second connector 220 into the receiving slot 2111, the guiding inclined surface 2311 of the locking element 230 effectively converts the force of the second connector 220 pressing the locking element 230 into a force pushing the locking element 230 to move toward the unlocked state, which is beneficial to the smooth contraction of the locking element 230 to the unlocked state, and facilitates the smooth insertion of the second connector 220 into the bottom of the receiving slot 2111.
