Background

The mobile electronic equipment can directly transmit signals and charge through the connector and the equipment, the connector usually adopts an elastic sheet or elastic needle scheme, and the elastic needle or the elastic sheet needs to be exposed and is conducted through pressing. However, since the flat plate needs to be frequently removed or put in, the elastic sheet or the elastic needle needs to be subjected to a force except for the deformation direction, the number of times is increased, or the moving force is too large, which leads to the reduction of the service life of the connector.

Taking the conventional pogo pin connector as an example, assuming that the pressing direction of the pogo pin is the Z direction, the electronic device needs to be frequently plugged into the pogo pin connector, and the force for moving the flat plate will not completely act on the Z direction under normal circumstances, so that the pogo pin in the connector will receive the forces from the X direction and the Y direction when plugged.

Specifically, as shown in fig. 2, 4 and 5, the plugging structure 100 includes an electrical connector 110, a bottom plate 120, a housing 190 and a guide 140, the electrical connector 110 is fixed on the bottom plate 120, the guide 140 is fixedly connected to the housing 190, the bottom plate 120 is sleeved on the guide 140, and through this, the bottom plate 120 can slide along the guide 140, so as to realize the movement of the bottom plate 120 relative to the housing 190 and drive the electrical connector 110 disposed on the bottom plate 120 to move.

The base plate 120 is movably connected to the housing 190, the magnetic member 150 is disposed on the base plate 120, and correspondingly, another magnetic element is disposed on the movable electronic device. When the electronic device is not inserted into the position, the attraction between the magnetic element on the electronic device and the magnetic member 150 on the floor is not sufficient to move the base plate 120, which is in the initial state as shown in fig. 6. When the electronic device needs to be inserted, the electronic device is placed on the housing 190, and the magnetic element 150 on the bottom plate 120 is attracted by the magnetic element on the electronic device, so that the bottom plate 120 is close to the housing 190, and drives the electrical connector 110 to move until the electrical connector protrudes out of the housing 190, and completes electrical connection with the interface on the electronic device, as shown in fig. 7. When the electronic device needs to be pulled out, the electronic device is moved away by a certain distance, so that the distance between the magnetic member 150 on the bottom plate 120 and the magnetic element on the electronic device exceeds a certain limit, and the magnetism is weakened or disappeared.

In one embodiment, the base plate 120 is connected to the housing 190 by an elastic member. When the base plate 120 is unstressed and in an initial state, the base plate 120 is away from the cabinet 190. When the electronic device needs to be inserted, the electronic device is placed on the chassis 190, and the magnetic member 150 on the bottom plate 120 is attracted by the magnetic element on the electronic device, so that the bottom plate 120 is close to the chassis 190, and the elastic member is elastically deformed. After the electronic device is pulled out, the magnetism is weakened or disappeared, the elastic member gradually recovers to the state when the elastic member is not deformed under the elastic action of the elastic member, and the elastic deformation force drives the bottom plate 120 to recover to the initial state.

In one embodiment, as shown in fig. 4 and 5, the guiding element 140 is a guiding post, the base plate 120 is provided with a guiding hole 121, and the base plate 120 is sleeved on the guiding post through the guiding hole 121. When the bottom plate 120 moves, the guide structure of the guide post and the guide sleeve ensures that the bottom plate 120 moves along the Z direction, and does not move like the X direction or the Y direction, so as to avoid generating component force in the X direction or the Y direction on the electrical connector 110 during the movement. Guide pillar, guiding hole 121 are a comparatively common guide structure, and other common guide structures also can be applied to the utility model discloses, like guide rail, guide pin bushing etc..

For the plugging structure 100 provided with the guide post and the guide hole 121, the size of the guide hole 121 is slightly larger than the size of the cross-sectional area of the guide post. A certain gap is left between the guide hole 121 and the guide post, so that the base plate 120 can rotate or move in the X direction or the Y direction to a certain extent when moving in the Z direction. Because the electronic equipment has certain error when being butted with the electric connector 110, and certain allowance is left in the X direction or the Y direction, the damage of the electric connector 110 caused by continuous butting can be prevented when the butting error is generated. With pogo pin connector example, the top of pogo pin connector is a sphere, when pogo pin connector need insert the hole in the middle of the electronic equipment, if hole axis and pogo pin connector bullet needle axis disalignment, because of the restriction of pulling out structure 100 guide structure again simultaneously, lead to pogo pin connector bullet needle can only follow the Z direction motion, the damage that can lead to pogo pin connector bullet needle is pegged graft by force. After a certain margin is left, the bottom plate 120 can drive the pogo pin connector to perform the play in the X direction or the Y direction, so that the hole axis and the pogo pin connector elastic needle axis are coaxial to restore, normal insertion can be performed, and damage is avoided.

Further, as shown in fig. 4, the guide hole 121 may be formed in an elliptical shape such that the length of the minor axis of the guide hole 121 is equal to or slightly greater than the diameter of the guide post and the length of the major axis of the guide hole 121 is greater than the diameter of the guide post. The base plate 120 is primarily rotatable or movable along the major axis of the guide hole 121, but is only rotatable or movable to a relatively limited extent along the minor axis of the guide hole 121. In fig. 4, the major axis direction of the guide hole 121 is the same as the width direction of the base plate 120, and the minor axis direction of the guide hole 121 is the same as the longitudinal direction of the base plate 120. With this arrangement, when the electronic device is pulled out, the bottom plate 120 is turned towards or away from the housing by a certain amount, which reduces the damage to the connector and prolongs the service life of the connector.

In some embodiments, as shown in fig. 4, the bottom plate 120 is provided with a recessed groove 123, the electrical connector 110 is located in the recessed groove 123, and the recessed groove 123 forms a semi-enclosed structure to completely enclose the electrical connector 110 in the recessed groove 123. The recessed groove 123 mainly has two functions: the first is to protect the electrical connector, when the electrical connector protrudes out of the housing 190 under the action of the bottom plate 120, or when the electrical connector is plugged into an electrical device, external force is prevented from being directly applied to the electrical connector; secondly, the concave groove 123 itself can play a certain guiding role, so as to ensure the butt joint precision of the electric connector 110 and the electric equipment.

In some embodiments, the magnetic force of the magnetic member 150 is adjustable. For some elastic electrical connectors 110, such as pogo pin connectors, after a long time of use, the conductive part of the connector is worn or the elastic element therein is elastically lowered, so that a larger pressing force is required to ensure the connection effect of the electrical connector, and at this time, only the magnetic force of the magnetic member 150 needs to be adjusted. The adjusting mode can be that the current magnitude of the electromagnet is controlled, and the larger the current magnitude is, the larger the magnetic force is; or by adjusting the position of the magnetic member 150 on the bottom plate 120, since the position of the magnetic element on the electronic device relative to the housing 190 is fixed, the distance between the magnetic member 150 and the magnetic element can be changed by adjusting the position of the magnetic member 150, so as to adjust the magnitude of the magnetic force.

In some embodiments, in order to ensure the alignment precision, a positioning member is disposed on the surface of the housing. Because the bottom plate moves along the guide piece, the electric connector has better positioning precision after the elastic piece is compressed. And a positioning piece is arranged on the surface of the machine shell and used for controlling the position of the electronic equipment when the electronic equipment is placed, so that the alignment precision during butt joint is improved. The positioning piece can be a positioning nail, a positioning boss or other common positioning structures.

In some embodiments, the electrical connector is a pogo pin connector or a pogo plate connector, and accordingly, the electronic device is provided with a contact, a contact piece, and the like corresponding to the pogo pin and the pogo plate.
