Connectors and equipment boxes

Abstract

The present invention relates to a connector and an equipment box. The connector includes a housing, an insulator, a contact, and a transfer conductive part. The transfer conductive part and the contact are conductively slidably matched up and down, and the transfer conductive part is used to conduct electricity with the conductive part of the printed circuit board, so that the contact can be conductively connected to the printed circuit board at different upper and lower positions through the transfer conductive part. When the position between the contact and the printed circuit board changes, the transfer conductive part can compensate for the position deviation between the contact and the printed circuit board. Since the transfer conductive part of the present invention is slidably matched with the contact, the contact is not easily deformed, and the transfer conductive part is also not easily deformed. After disassembly and assembly, the contact and the transfer conductive part can be used and installed normally for multiple times, and have a long service life. This solves the problem of the current connector having a short contact life and inconvenient maintenance caused by deforming the contact to compensate for the connector position deviation during installation.

Description

Technical Field

[0001] The invention relates to a connector and an equipment box. Background Art

[0002] Some devices are fixed with a printed circuit board. In order to connect the printed circuit board inside the device box with the circuit outside the device box, an external socket is generally installed on the wall of the device box. Then, the external socket is connected to the printed circuit board through an adapter printed circuit board connector to realize power or signal transmission.

[0003] Due to the limited space in the equipment box, the existing installation sequence is to first connect the printed circuit board connector to the printed circuit board, then fix the printed circuit board in the equipment box, and finally insert the external connector into the equipment box to mate with the printed circuit board connector. Because the external connector is directly plugged into the printed circuit board connector during installation, this assembly sequence cannot be changed. If the external connector is inserted into the equipment box first, the printed circuit board connector cannot move in the plugging direction and cannot mate with the external connector.

[0004] A Chinese patent with authorization announcement number CN211456101U and authorization announcement date of September 8, 2020, discloses an adapter connection in which the contacts of the adapter connector are crimped and fixed to the conductive portion of the printed circuit board. A threaded locking sleeve is provided on the inner side of the contact, and the crimped section and the conductive portion are compressed by the threaded locking sleeve and the locking member. When there is a large deviation between the position of the printed circuit board and the position of the connector, the contact needs to deform to compensate for the distance between the printed circuit board and the connector, which has a strong tolerance. However, the lifespan of the contacts of this connector is shortened after deformation, and the deformed contacts are inconvenient to disassemble and assemble, reducing maintenance efficiency. Summary of the Invention

[0005] The object of the present invention is to provide a connector for solving the problem of short contact life and inconvenient maintenance caused by the current connector deforming the contact to compensate for the connector position deviation during installation; in addition, the object of the present invention is also to provide an equipment box using the above-mentioned connector.

[0006] The connector of the present invention adopts the following technical solutions:

[0007] Connectors include:

[0008] case;

[0009] The insulator is configured on the housing, and the front end is used to extend into the equipment box;

[0011] The transfer conductive part is in conductive sliding cooperation with the contact part up and down. The transfer conductive part is used to conduct electricity with the conductive part of the printed circuit board, so that the contact part can be conductively connected to the printed circuit boards at different positions up and down through the transfer conductive part.

[0012] Beneficial effect: The connector of the present invention is provided with a transition conductive part that can slide up and down with the contact part. When the position between the contact part and the printed circuit board changes, the transition conductive part can compensate for the position deviation between the contact part and the printed circuit board, thereby realizing normal conductive connection between the two. Since the transition conductive part of the present invention slides with the contact part, the contact part is not easy to deform, and the transition conductive part is also not easy to deform. After disassembly and assembly, the contact part and the transition conductive part can be used and installed normally for many times, and have a long service life. This solves the problem of short contact life and inconvenient maintenance caused by the current connector deforming the contact part to compensate for the connector position deviation during installation.

[0013] Furthermore, the transition conductive member is provided with a threaded hole for engaging with a threaded fastener. The threaded hole extends vertically, and the transition conductive member is locked in place with the insulator or contact member so that the threaded fastener fastens the transition conductive member to the conductive portion of the printed circuit board, achieving a conductive connection.

[0014] Furthermore, the contact member includes a socket that is electrically conductively slidably matched with the transfer conductive member, and the transfer conductive member has a screw sleeve inserted into the socket, and the inner hole of the screw sleeve forms the threaded hole. The socket and the screw sleeve are plug-in matched, and the structure is more compact.

[0015] Furthermore, to enhance operational stability of the transition conductive element, the transition conductive element also includes a contact cap connected to the upper end of the threaded sleeve. The upper end surface of the contact cap is configured to press against the conductive portion of the printed circuit board. The contact cap and the threaded sleeve define a slot for the socket. The socket is inserted into the slot, and the interaction between the inner and outer sidewalls of the slot and the socket reduces the swing amplitude of the transition conductive element.

[0016] Furthermore, the outer wall of the socket has ribs that slide with the inner wall of the contact cap, and the inner wall of the socket is in conductive contact with the outer wall of the screw sleeve, thereby reducing the swing amplitude of the switching conductive part and ensuring good conductive contact between the switching conductive part and the socket.

[0017] Furthermore, in order to improve the electrical conductivity and facilitate installation, the socket is provided with at least two slots extending from top to bottom. The slots can be provided so that the radial dimension of the socket can be varied according to actual conditions, so that the socket has good electrical contact with the transition conductive member.

[0018] Furthermore, the contact cap is arranged on the insulator in an upward and downward guiding sliding manner, and the contact cap is provided with a rotation-stopping boss that cooperates with the insulator to stop rotation. The contact cap is arranged on the insulator, which has good stability, and the rotation-stopping boss has a simple structure and is easy to install and process.

[0019] Furthermore, the anti-rotation boss cooperates with the upper and lower stops of the insulator to prevent the contact cap from separating from the insulator. The anti-rotation boss cooperates with the upper and lower stops of the insulator to prevent the transfer conductive member from separating from the insulator, while the structure of the contact cap is relatively simple.

[0020] Furthermore, the insulator includes a left insulating block and a right insulating block, which clamp and fix the contact piece when the left insulating block and the right insulating block are aligned. When the insulator is separated, it is convenient to install the contact piece.

[0021] Furthermore, the contact cap is configured to slide on the insulator in an up-and-down manner, and the contact cap and the insulator cooperate with each other to prevent the contact cap from separating from the insulator, thereby preventing the transfer conductive part from separating from the insulator and facilitating installation.

Therefore, they should not be understood as limitations on the present invention.

[0057] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0058] Specific embodiment 1 of the connector of the present invention:

[0059] like Figures 1 to 10 As shown, the connector of the present invention is a transfer connector, the front end of the connector is used to connect with the printed circuit board 5, and the rear end is used to be plugged into the adapter plug.

[0060] The connector comprises a housing 1, an insulator 2, and contacts 3. Housing 1 is a conductive metal shell bolted to the wall of an equipment case 4. The equipment case 4 has connector mounting holes. The connector contacts 3 and insulator 2 are inserted into the equipment case 4 through the holes and connected to a printed circuit board 5 within the equipment case 4. The printed circuit board 5 comprises a body 51 and a conductive portion 52. The equipment case 4 is in conductive contact with the connector housing 1 to shield the contacts 3 within the housing 1.

[0061] The insulator 2 is fixed to the shell 1, and the front end extends into the device case 4, and the contact 3 is fixed in the insulator 2. The front end of the contact 3 extends into the device case 4 along with the insulator 2, and the rear end is used to plug into the contact of the adapter plug. The contact 3 extends front and back as a whole, and includes three parts, namely the socket 31 at the front end, the pin 32 at the rear end, and the connecting conductor 33 connecting the socket 31 and the pin 32. The three parts are arranged front and back. In this embodiment, the connecting conductor 33 is riveted to the socket 31 and fixed to the pin 32 by rivets. The split structure of the contact 3 is easy to process and reduces processing costs. In other embodiments, the connecting conductor can be connected to the socket or pin by welding, one-piece molding, etc.

[0062] The connector includes a transition conductive member 6 that slides vertically with the socket 31. The transition conductive member 6 includes a contact cap 61 and a screw sleeve 62. The lower end of the screw sleeve 62 is inserted into the socket 31, and the contact cap 61 is connected to the upper end of the screw sleeve 62. In this embodiment, the contact cap 61 and the screw sleeve 62 are integrally provided. In other embodiments, the contact cap can also be provided separately from the screw sleeve, for example, by welding.

[0063] After the fastening bolts 7 are tightened to tighten the conductive portion 52 of the printed circuit board and the adapter conductive member 6, the upper end face 611 of the contact cap 61 is used to press and electrically contact with the conductive portion 52 of the printed circuit board, and the adapter conductive member 6 and the socket 31 of the contact member 3 are conductively slidably matched up and down. The contact member 3 is conductively connected to the printed circuit board 5 through the adapter conductive member 6. At the same time, since the adapter conductive member 6 can slide up and down, that is, the adapter conductive member 6 can move in a direction perpendicular to the printed circuit board 5, the contact member 3 can adapt to the printed circuit board 5 at different upper and lower positions and be conductively connected to the printed circuit board 5 at different upper and lower positions.

[0064] The screw sleeve 62 extends vertically, and the inner hole of the screw sleeve 62 is a threaded hole 621 that cooperates with the fastening bolt 7. The printed circuit board conductive portion 52 is provided with a printed circuit board through hole 521 corresponding to the threaded hole 621. The fastening bolt 7 passes through the printed circuit board through hole 521 and is threadedly connected to the screw sleeve 62, fastening the printed circuit board conductive portion 52 and the transition conductive member 6. The upper end surface 611 of the contact cap 61 of the transition conductive member 6 is pressed and conductively contacted with the printed circuit board conductive portion 52. The fastening bolt 7 in this embodiment constitutes a threaded fastener.

[0065] The contact cap 61 is configured to slide upward and downward on the insulator 2. Figure 8 and Figure 9As shown, the contact cap 61 is provided with a stop boss 612 that engages with the insulator 2 for rotational engagement. The insulator 2 is provided with a stop groove 21 that slides vertically with the stop boss 612. The upper groove wall 211 of the stop groove 21 engages with the stop boss 612 in a vertically interlocking manner, thereby interlocking the stop boss 612 with the insulator 2 to prevent separation of the contact cap 61 from the insulator 2. In this embodiment, two stop bosses 612 are symmetrically arranged. The contact cap 61 includes a cylindrical cap body 613 that extends vertically, with the stop boss 612 disposed at the lower end of the cap body 613.

[0066] To improve the electrical stability between the transition conductive member 6 and the contact member 3, the socket 31 is provided with four vertically extending slots 34, evenly spaced around the circumference of the socket 31. The slots 34 extend from top to bottom to the lower end of the socket 31, with their upper ends communicating with the upper opening of the socket 31. This allows the upper end of the socket 31 to retract inward. In this embodiment, the inner wall of the socket 31 is in conductive contact with the outer wall of the screw sleeve 62. By slightly retracting the upper end of the socket 31 slightly toward the center, good conductive contact between the socket 31 and the screw sleeve 62 is ensured.

[0067] In this embodiment, the screw sleeve 62 and the contact cap 61 form a slot 63 for the socket 31 to be inserted. The slot 63 is an annular groove. The outer peripheral surface of the screw sleeve 62 is the inner groove wall of the slot 63, and the inner peripheral surface of the cap body 613 is the outer groove wall of the slot 63.

[0068] A rib 35 is provided on the upper portion of the socket 31 and is located on the outer periphery of the socket 31. The rib 35 extends along the circumference of the socket 31. The rib 35 is in conductive sliding engagement with the inner wall of the contact cap 61 to prevent relative swinging of the screw sleeve 62 and the socket 31, thereby improving the contact reliability between the transition conductive member 6 and the contact member 3.

[0069] The connector of the present invention adopts the form of plugging the threaded sleeve 62 and the plug sleeve 31 together, and the inner hole of the plug sleeve can avoid the fastening bolt, which not only increases the release area between the contact member 3 and the transition conductive member 6, but also makes the structure more compact.

[0070] For ease of assembly, the insulator 2 in this embodiment is a split structure that is matched left and right. The insulator 2 includes a left insulating block 22 and a right insulating block 23. After the left insulating block 22 and the right insulating block 23 are matched and fixed by bolts, the contact member 3 is clamped and fixed. At the same time, the switching conductive member 6 is also clamped between the left insulating block 22 and the right insulating block 23.

[0071] When assembling the equipment box, install the connector into the connector mounting hole of the equipment box, fix the printed circuit board 5 in the equipment box, and fasten the printed circuit board conductive part 52 on the printed circuit board 5 with the transfer conductive part 6 by bolts. If the printed circuit board 5 has position deviation in the vertical direction, it can slide up and down with the transfer conductive part 6 through the socket 31 to ensure the normal installation of the connector and the printed circuit board 5. Figure 5 and Figure 6 As shown, when the vertical distance between the printed circuit board 5 and the centerline of the connector is between L1 and L2, normal installation and use are possible. During the tightening process of the fastening bolt 7 and the nut 62, if the vertical distance between the printed circuit board 5 and the centerline of the connector is greater than L1, the nut 62 cannot rotate and, under the action of the fastening bolt 7, the nut 62 will move upward until the upper end face 611 of the contact cap 61 contacts the conductive portion 52 of the printed circuit board 5. At this point, the fastening bolt 7 is continued to be tightened until the fastening bolt 7 fastens the conductive portion 52 of the printed circuit board to the transfer conductive member 6. The contact cap 61 is then pressed against the conductive portion 52 of the printed circuit board, achieving good electrical contact. If the vertical distance between the printed circuit board 5 and the centerline of the connector is equal to L1, the upper end face of the contact cap directly presses against the conductive portion 52 of the printed circuit board 5.

[0072] In other embodiments, multiple ribs may be provided up and down, or multiple convex points may be provided instead of the ribs.

[0073] In other embodiments, in addition to the threaded sleeve and sliding sleeve combination in the above-mentioned embodiment, a conductive post can be provided on the transition conductive member, and a socket can be provided on the contact member to be plugged into the conductive post. In addition, a threaded hole parallel to the conductive post can be provided on the transition conductive member. In this case, the transition conductive member can be in the form of a conductive block, with the conductive block provided on the contact member instead of the sliding sleeve, and the socket provided on the conductive block. In other embodiments, a conductive post can also be provided on the contact member, and a socket can be provided on the transition conductive member to be conductively plugged into the conductive post.

[0074] In other embodiments, a convex-concave mating structure extending vertically between the threaded sleeve and the sliding sleeve can be provided to prevent rotation, in which case the transition conductive member and the contact member can be prevented from rotating. In other embodiments, the transition conductive member and the insulator can be prevented from rotating in other ways, such as: the outer peripheral surface of the cylinder of the contact cap is non-circular, and the outer peripheral surface is provided with a rotation-preventing flat surface, and the rotation-preventing flat surface cooperates with the insulator to prevent rotation. A guide post can also be provided at the lower end of the contact cap, and a socket for inserting the guide post can be provided on the insulator.

[0075] In other embodiments, the printed circuit board conductive part may not be in direct contact with the transfer conductive part, and the two are electrically conductive by tightening bolts.

[0076] In other embodiments, when the length of the threaded sleeve is long enough, the transition conductive contact piece may not have an upper and lower stop fitting relationship with the insulator.

[0077] In other embodiments, the number of slots can be set as needed, such as two, three, or any other number. In other embodiments, only the sliding sleeve and the contact cap can be in conductive contact, in which case the upper end of the sliding sleeve can be expanded outward. Of course, in other embodiments, only the sliding sleeve and the screw sleeve can be in conductive contact.

[0078] In other embodiments, a stopping structure may be provided on the contact cap to stop the insulator. For example, a groove may be provided on the contact cap, and a stopper that matches the groove may be provided on the insulator.

[0079] In other embodiments, the printed circuit board may be fixed to the transfer conductive member by riveting. In other embodiments, the printed circuit board may be fixed by snapping, and spot welding may be performed after snapping to ensure a reliable connection.

[0080] Specific embodiment 1 of the equipment box of the present invention includes a box body and a connector fixed on the box body, a printed circuit board connected to the connector is provided in the box body, and the structure of the connector is the same as that of the connector described in any of the above specific embodiments, wherein the structure of the printed circuit board and the box body is also the same as that described in the above connector specific embodiment.

[0081] Specific embodiment 2 of the equipment box of the present invention, the structure of the equipment box in this embodiment is different from that of the above embodiment only in that, Figure 11 and Figure 12 As shown, in this embodiment, the printed circuit board conductive portion 52 includes a board conductive portion 521 fixed to the board body 51 of the printed circuit board 5 and a transition piece 522 conductively connected to the board conductive portion 521. The transition piece 522 is pressed and conductively contacted with the contact cap 61.
