And the CPA structure 3 is assembled with the female end 1, that is, the CPA structure 3 can be assembled to a predetermined position on the female end 1, so that whether the male end 2 and the female end 1 are in butt joint can be judged by whether the CPA structure 3 is assembled to the predetermined position on the female end 1.

It should be noted that, the CPA structure 3 may have a plurality of assembling positions on the female end 1, and the assembling device where the CPA structure 3 is located when the assembling is completed herein may refer to one or more assembling positions, so that the CPA structure 3 can be moved to the assembling position with respect to the female end 1 only when the male end 2 and the female end 1 are brought into the abutting state.

The limiting structure may be disposed at the female end 1 or disposed at the CPA structure 3, and when the male end 2 and the female end 1 enter the butt-joint state, the limiting structure should exit from the current limiting position at this time, so that the CPA structure 3 can be assembled to a predetermined position on the female end 1, and the assembly requirement is completed. Regarding the force transmission requirements between the female end 1 and the snap 4: in some embodiments, in this assembled state, a fixed connection may be formed between the CPA structure 3 and the female end 1, where the fixed connection needs to meet the force requirement between the buckle portion 4 and the wire structure 5, so that the buckle portion 4 may perform force transmission through the CPA structure 3 and the female end 1, so as to perform force transmission through the assembled connection of the CPA structure 3 and the female end 1; of course, in some embodiments, after the assembly between the CPA structure 3 and the female end 1 is completed, a connection structure may be further provided, so that force can be transferred through the connection structure, or auxiliary force transfer can be performed.

In the above-mentioned connector, when assembling, the CPA structure 3 is placed in advance, so that the CPA structure 3 and the fastening portion 4 both enter the preassembled state, and at this time, the CPA structure 3 cannot be assembled with the female end 1. At this time, the female end 1 and the male end 2 need to enter a butt joint state, and then the CPA structure 3 and the female end 1 are assembled correspondingly, so as to determine whether the female end 1 and the male end 2 enter the butt joint state through whether the CPA structure 3 can be assembled. In a specific application, after the female end 1 has been connected to the wire structure 5, after the CPA structure 3 is assembled with the female end 1, the connection between the buckle portion 4 and the wire structure 5 may be further completed. In the connector, the installation states of the CPA structure 3 and the buckling part 4 are comprehensively considered, the CPA structure 3 and the buckling part 4 are assembled together, the number of parts is reduced, and the installation convenience is improved. In addition, the fastening portion 4 is required to bear a tensile force, and is generally stressed little when the female end 1 and the male end 2 are in a butt joint state, but is not in a butt joint state, so that the whole use is not affected. In summary, the connector can effectively solve the problem of poor assembly effect of the current connector.

In some embodiments, regarding the setting of the above-mentioned limiting structure, the CPA structure 3 in the prior art may be referred to for corresponding setting, and may also be set as required. For convenience of operation, the CPA structure 3 and the female end 1 can be made to be: one has an elastic buckle 7 as the above-mentioned limit structure, and the other has a limit shoulder 6 which abuts against the limit structure.

When the female end 1 and the male end 2 do not enter the abutting state, the elastic buckle 7 can abut against the limiting shoulder 6 to block, namely, prevent the CPA structure from being assembled with the female end 1. When the female end 1 and the male end 2 enter the abutting state, the pushing part on the male end 2 can push the elastic buckle 7 to elastically deform until the elastic buckle is separated from the limiting shoulder 6, so that the blocking is not performed any more, and the CPA structure 3 can be assembled with the female end 1 correspondingly.

In some embodiments, the elastic buckle 7 may be disposed at the female end 1 or the male end 2, and specifically may be disposed as required.

In some embodiments, the CPA structure 3 therein may be made to comprise said resilient catch 7. Correspondingly, the elastic buckle 7 can be provided with a guiding inclined plane 8 matched with the male end 2, so that the elastic buckle 7 can be propped against the male end 2 and the propping force is used for pushing the elastic buckle 7 to elastically deform so as to be separated from the abutting with the limiting shoulder 6. And the elastic buckle 7 is provided with a clamping convex 13 for propping against the limit shoulder 6.

In some embodiments, the elastic buckle 7 and the CPA structure 3 body may be integrally formed, and the elastic deformation is realized by using the elasticity of the elastic buckle. If the elastic buckle 7 comprises an elastic handle integrally formed with the CPA structure 3 at one end, the other end of the elastic handle extends towards the male end 2 and is suspended so as to be deformable to different positions, and the clamping protrusion 13 and the guiding inclined plane 8 are arranged at the end. For better position assurance, the two sides of the female end 1 far away from each other may be provided with elastic buckles 7, that is, the portions of the two sides of the CPA structure 3 far away from the female end 1 are provided with the elastic buckles 7.

In some embodiments, the elastic buckle 7 may also be an elastic movable pin, including a pin member slidably matched with the CPA structure 3 body and an elastic member, such as a spring, for pushing the pin member to a predetermined position, where the pin member is provided with a blocking protrusion 13 and a guiding inclined plane 8, under the action of the elastic member, the pin member may be pushed to move until the blocking protrusion 13 abuts against the limiting shoulder 6, and when the guiding inclined plane 8 abuts against the male end 2, the abutting force at least forms a separation that causes the elastic member to deform, so that the pin member moves until the blocking protrusion 13 is separated from the limiting shoulder 6.

In some embodiments, it is preferred here that when the CPA structure 3 can be blocked by the limiting structure to block the assembly with the female end 1, the CPA structure and the female end 1 structure are assembled to the elastic buckle 7 and abut against the limiting shoulder 6, and the CPA structure can be clamped with the female end 1 structure to form a pre-assembled state, and of course, the clamped connection should not completely block the assembly between the CPA structure 3 and the female end 1, that is, in the clamped state, an external force can be further applied to the CPA structure 3 so as to be out of the clamped state to enter a corresponding assembly position.

When the preassembly state is set, in the preassembly state, the fastening portion 4 can be assembled with the wire structure 5 correspondingly, but the wire structure 5 needs to form a redundant portion between the fastening portion 4 and the female end 1, so that when the wire structure 5 and the fastening portion 4 are fixedly connected with the female end 1, the fastening portion 4 can still move along with the CPA structure 3, so that the CPA structure 3 can be assembled from a preassembly position to a complete assembly position relative to the female end 1. At this time, the flexibility of the end portion of the wire structure 5 is mainly utilized so that the linear distance between the portion connecting the locking portion 4 and the portion connecting the female end 1 can be adjusted.

Of course, in some embodiments, it is contemplated that the internal wire structure 5 may not be made redundant, or that the redundant may be detrimental to overall structural performance, or for other reasons. In the preassembled state, the catch 4 can then be made not to connect with the wire structure 5 but to be movable relative to one another. And when the CPA structure 3 and the female end 1 are assembled, the fastening part 4 is connected with the wire structure 5.

Meanwhile, the clamping connection is realized in the preassembly state, so that the position stability between the CPA structure 3 and the female end 1 can be better ensured, and the unstable state of the CPA structure 3 in the butt joint process of the female end 1 and the male end 2 is effectively avoided, and the final assembly failure is caused.

In some embodiments, when the CPA structure 3 is assembled with the female end 1, the CPA structure 3 is clamped with the female end 1, so as to achieve a fixed connection. Of course, the fixed connection may be realized by other means, such as screw connection, bolt connection, magnetic connection, etc. So that the CPA structure 3 is stabilized in the assembled position. The female end 1 may be provided with a plurality of slots in its structure to correspond to the preassembled state and the assembled state, respectively, and the clip on the CPA structure 3 is engaged with each slot, in the preassembled state, with one of the slots, and in the assembled state, with the other slot.

In some embodiments, in general, the female end 1 and the male end 2 are in butt joint, in order to ensure the stability of the butt joint, an operation button 9 is provided on the female end 1, so as to be used as an unlocking button, and the unlocking button is used for realizing free butt joint of the female end 1 and the male end 2. And during locking, the female end 1 and the male end 2 cannot be freely butted, the specific distance is that when the male end 2 and the female end 1 are in butt joint, the male end 2 and the female end 1 cannot be separated at the moment when the unlocking button is locked, and when the unlocking button is unlocked, the male end 2 and the female end 1 can be operated to be separated.

At this time, the limiting portion 10 may be correspondingly disposed on the CPA structure 3, so that the limiting portion 10 is used for limiting the operating button 9 to prevent the operating button 9 from operating in the unlocking direction when the CPA structure 3 is docked with the female end 1, and the male end 2 and the female end 1 cannot be separated due to the fact that the operating button 9 cannot be unlocked.

The form of the operation button 9 is not limited, and the operation button 9 can be blocked in the slot of the female end 1 when in a natural state, so that the male end 2 can be prevented from entering the slot. And when the male end 2 is unlocked, the male end 2 can be embedded into the male end 2 when the male end is separated from the slot and the operating button 9 can be locked again, so that the male end cannot be separated from the slot. In this case, the above-mentioned limiting portion 10 may be a limiting pressing groove to prevent the operation button 9 from moving, so as to maintain the operation button 9 in the locked state or in the unlocked state.

In some embodiments, the CPA structure 3 may be set as required, so as to be able to achieve the target function. In particular, the CPA structure 3 may be made to include a barrel portion 11, where the barrel portion 11 is slidably engaged with the female end 1 to achieve a sliding fit, and one end of the barrel portion 11 has a snap-fit portion 4, and the other end is irradiated on the end of the female end 1.

It is of course also possible to provide cavities in the female end 1 to enable the CPA structure 3 to be inserted.
