The external socket 1 passes through the opening on the panel 4 and is fixed on the panel 4 through the flange 11 on the outer shell 16 of the external socket 1. Preferably, the flange 11 is fixed on the panel 4 through the screw 12. The printed board socket 2 is fixed on the printed board 3.

[0081] The external socket 1 comprises at least one first contact component 13, the printed board socket 2 comprises at least one second contact component 21, and the tail of the first contact component 13 is used to extend the contact end of the second contact component 21 to adapt to the insertion of the external socket 1. The outer shell 16 of the contact end can still be adapted to the insertion of the printed board socket 2 after being rotated by 180 degrees.

[0082] The printed board socket 2 is provided with split grooves 224 on at least two surfaces, which can enable the contact end of the first contact component 13 to be inserted into the clamping cavity of the second contact component 21, and the split grooves 224 on at least two adjacent surfaces are communicated, so that when the external socket 1 is first fixed on the panel 4, the printed board socket 2 can be connected with the external socket 1 from at least three directions, and after the connection is completed, the printed board socket 2 is fixed with the printed board 3, the connection direction of the printed board socket 2 includes from top to bottom, from bottom to top and from right to left, and the corresponding printed board is located at the upper end, lower end and right side of the printed board socket. The above-mentioned connection in the same connection direction also includes straight connection (the contact components are parallel to each other, as shown in Figure 4A 、 4B , 5A, 5B) and inclined connection (the contact components are inclined to each other, as shown in Figure 6A 、 6B , 7A, 7B). When the printed board socket 2 is first fixed on the printed board 3, the tail of the external socket 1 can be connected with the printed board socket 2 through the panel 4, at this time, the printed board 3 is located above, below or right side of the printed board socket 2, and the connection between the printed board socket 2 and the external socket is straight connection or inclined connection. When the external socket 1 is connected with the printed board socket 2 in straight connection, the printed board 3 is perpendicular or parallel to the panel 4, and when the external socket 1 is connected with the printed board socket 2 in inclined connection, the printed board 3 is inclined to the panel 4.

[0083] The edge of the split groove 224 is provided with a chamfer, and the edge adjacent to the split groove of the second contact component is also provided with a chamfer, so as to meet the connection requirement in multiple directions, and meanwhile, the connection guidance is good.

[0084] The connector of the present application can be compatible with the installation tolerance of the printed board relative to the panel through the floating between the external socket 1 and the printed board socket 2. The printed board socket 2 and the external socket 1 have floating in at least one direction of the vertical panel direction (Z-axis direction), the panel length direction (X-axis direction) and the panel height direction (Y-axis direction).

[0085] The contact end of the first contact component 13 is a sheet type contact end 133, and when there are multiple first contact components, the sheet type contact ends 133 are parallel to each other. The setting of the sheet type contact end can enable the length (Z-axis direction) and width (Y-axis direction) of the sheet type contact end 133 inserted into the front clamping cavity of the second contact component 21 to be adjusted when the external socket 1 and the printed board socket 2 are connected, so as to realize the relative floating of the external socket 1 and the printed board socket 2 in the Z-axis direction and the Y-axis direction. The external socket 1 and the printed board socket 2 of the present application can also realize the relative floating of the two in the X-axis direction through the floating of the contact end of the first contact component 13 and / or the second contact component 21 in the thickness direction.

[0086] In the embodiment of the present application, the connector can satisfy the floating of the PCB relative to the panel in the X-axis direction, which is realized by the floating contact provided on the printed board socket, and the floating compatibility between the printed board and the panel in the X-axis direction is realized by the floating of the floating contact.

[0087] The connector of the embodiment of the present application can also satisfy the floating of the PCB relative to the panel in the Y-axis direction, which is realized by the contact length of the contact components of the external socket 1 and the printed board socket 2 in the Y-axis direction.

[0088] The connector of the embodiment of the present application can also satisfy the floating of the PCB relative to the panel in the Z-axis direction, which is realized by the contact length of the contact components of the external socket 1 and the printed board socket 2 in the Z-axis direction.

[0089] One end of the first contact component 13 is matched with the contact inside the external plug to realize the transmission of the electrical signal, and the other end is matched with the contact of the printed board socket 2 to realize the transmission of the electrical signal. The contact component 13 comprises a pin 131 for matching with the contact inside the external plug and a blade contact 133 connected with the pin 131 and formed with a blade contact end at the tail for matching with the contact of the printed board socket 2. The connection between the pin 131 and the blade contact is realized by rivet 132, screw or welding. The pin 131 and the blade contact can also be an integrated structure.

[0090] In the embodiment of the present application, the first contact component 13 has a plurality of blade contact ends, which are parallel to each other and perpendicular to the flange surface 11, but are not limited thereto.

[0091] In the embodiment of the present application, the pin 131 at the front end of the first contact component is a circular structure, and the contact end at the tail is a blade structure, the circular structure and the blade structure are connected through a blade extension arm, and the surface of the blade structure is parallel to the axis of the circular structure. The blade extension arm and the blade contact end are an integrated structure, which are connected through rivet, welding, screw or the like between the circular pin and the blade pin, or the blade and the circular pin are made into an integrated structure. Preferably, the blade extension arm and the blade contact end are integrally formed and connected through a 90-degree bending part. The blade extension arm and the blade contact end are provided with chamfers outside the connection end of the bending part. The first contact component 13 is also provided with a step for matching with the first insulator 14 to fix the step, which matches with the first insulator 14 to fix the contact component. The edge of the blade contact end 133 is provided with a chamfer for realizing the insertion guide.

[0092] In the embodiment of the present application, the first insulator 14 is a four-body buckling structure, which comprises upper and lower two parts attached to the blade extension arm and front and rear two parts matched with the front end of the blade contact end.

[0093] In another embodiment of the present application, the first contact component comprises a front end pin, a rear end blade contact, and a blade extension arm connecting the pin and the blade contact, and the blade contact is capable of elastically floating in the X-axis direction between the blade extension arm, thereby satisfying the floating requirement between the printed board and the panel in the X-axis direction.

[0094] The outer socket 1 also has a shielding grounding spring 15 in the groove 17 at the tail end, which is in contact with the panel opening when the outer socket 1 is fixedly assembled on the panel 4, thereby playing a shielding role.

[0095] The shielding grounding spring 15 has a C-shaped structure and multiple elastic contacts in cantilever beam or simply supported beam structure, and the elastic protrusions of the shielding grounding spring are in contact with the panel opening when the outer socket 1 passes through the panel opening, thereby realizing the shielding function.

[0096] The printed board socket comprises a second insulator 22 and at least one second contact component 21 assembled in the second insulator 22, the front end of the second contact component 21 is capable of floating in the X-axis direction in the second insulator 22, and the second insulator 22 also has a space for the front end of the second contact component 21 to twist in the X-axis direction.

[0097] In the embodiment of the present application, the second insulator 22 is provided with an insulator pin 221 for guiding and fixing when the printed board socket 2 is connected and fixed to the printed board 3.

[0098] The front end of the second contact component 21 is connected to the blade contact of the first contact component 13 through the clamping cavity, and the rear end is connected to the printed board 3 through the fixing structure, thereby realizing the transmission of the electrical signal from the outer socket to the printed board. In the embodiment of the present application, the contact component is connected to the printed board through the contact pin 211, which is welded to the printed board, directly contacted to the printed board, or screwed to the printed board 3.

[0099] The second contact component 21 comprises a contact 212 having a clamping cavity for the plug-in fitting of the blade contact of the first contact component at the front end, and a fixing member 214 for twisting the two wall bodies of the clamping cavity of the contact 212 and the blade contact in the same direction, thereby realizing the floating in the X-axis direction.

[0100] The contact 212 can be a one-piece, two-piece or multi-piece structure. In the embodiment of the present application, the contact 212 is a two-piece structure, which includes two oppositely arranged contact pieces, and the front ends of the two contact pieces are oppositely bent to form a clamping portion, and the fixing member 214 is located outside the clamping portion, which can satisfy the requirement of elastic deformation space of the clamping portion when the connector is inserted, and can drive the contact piece on the other side of the clamping portion to move in the same direction when the contact end piece of the plug-in end drives the contact piece on one side of the clamping portion to move, thereby realizing the floating in the X-axis direction.

[0101] In the embodiment of the present application, the second contact member 21 further includes an elastic member 213 for providing elastic force to the contact 212. Preferably, the elastic member is a spring fixed on the two sides of the contact, which is fixed outside the two contact pieces of the contact to provide elastic force inward. At this time, the fixing member 214 is located outside the elastic member 213.

[0102] In the present application, the fixing member 214 is a U-shaped structure, which is clamped outside the clamping portion of the contact, and ensures that the torsion directions of the two sides of the clamping portion are consistent, thereby ensuring reliable contact during the floating of the contact. The surface of the fixing member 214 cooperating with the contact 212 or the elastic member 213 is a circular arc surface 2141, so as to ensure good contact, and the surface contacting with the second insulator 22 is a flat surface 2142. The second insulator 22 is provided with a cavity 223 for the floating of the contact 212 and the fixing member 214 in the X-axis direction, and a guide surface 222 cooperating with the flat surface 2142 of the fixing member 214 to guide the contact during the floating of the contact.

[0103] When the connector is inserted, the contact end piece of the external socket is aligned with the clamping cavity of the contact member of the printed board connector, and the two are normally inserted without floating in the X-axis direction.

[0104] When the contact end piece of the external socket is deviated to the left of the printed board socket, the contact end piece first contacts the contact piece of the printed board socket contact member on the left side and moves to the left side, and under the action of the fixing member, the contact piece of the printed board socket contact member on the right side also moves to the left side. The printed board socket contact member realizes linkage under the action of the U-shaped fixing member, so that the two sides of the contact end piece of the external socket can simultaneously contact the two contact pieces of the printed board socket contact member, thereby ensuring the contact reliability.

[0105] When the contact end piece of the external socket is deviated to the right of the printed board socket, the contact end piece first contacts the contact piece of the printed board socket contact member on the right side and moves to the right side, and under the action of the fixing member, the contact piece of the printed board socket contact member on the left side also moves to the right side. The printed board socket contact member realizes linkage under the action of the U-shaped fixing member, so that the two sides of the contact end piece of the external socket can simultaneously contact the two contact pieces of the printed board socket contact member, thereby ensuring the contact reliability.
