Description

Technical Field

[0001] This invention belongs to the field of connector technology, specifically relating to a PCB connector structure with a mating angle and easy installation. Background Technology

[0002] Electrical connectors are widely used in communications, industry, transportation, and other fields, requiring fast and reliable connections between plugs and sockets. When electrical connectors are used in server racks, to achieve rapid connection between the PCB board inside the rack and the power supply outside the rack, a PCB socket is typically plugged into the PCB board inside the rack, and then a square socket is plugged into the PCB socket. The square socket is fixed to the rack panel, and then the plug connecting to the power supply outside the rack is plugged into the square socket. This two-piece connector structure (with separate PCB socket and square socket) not only quickly transmits power from outside the rack to the PCB board inside the rack, but also facilitates automated production and assembly of the PCB board, thus gaining widespread application in the communications field.

[0003] Currently, in two-piece connector structures, the PCB socket and the square socket can only be horizontally mated. When encountering special requirements in actual production, the PCB socket needs to be offset at a certain angle to mate with the square socket, thus achieving an angled connection between the plug and the square socket to accommodate the spatial positions of various components in actual production. Existing two-piece connector structures cannot achieve this angled mating. The PCB socket includes an insulator and contacts. The insulator typically includes an insulator shell and an insulator cover. After the contacts are placed inside the insulator shell, the insulator cover is used to cover and fix them to the insulator shell, thus securing the contacts within the insulator. The contacts require two non-metallic parts (insulator shell and insulator cover) to fasten and fix them, resulting in a complex structure and at least two steps in the installation process. In summary, existing PCB sockets have a single mating direction, cannot meet the requirements for angled mating, have a complex structure, high manufacturing costs, and complicated installation, thus limiting the application scope of this type of PCB socket. Summary of the Invention

[0004] To address the aforementioned technical problems of PCB sockets having a single mating direction and complex structure, this invention provides a PCB connector structure with a mating angle and easy installation.

[0005] The objective of this invention is achieved through the following technical solution. According to this invention, a PCB connector structure with an engagement angle and easy installation is provided, comprising an insulator and a contact. The insulator is integrally formed and has a blind hole for inserting the contact. The contact's insertion hole structure is inclined, and a cavity matching the insertion hole structure is provided inside the blind hole. An inclined surface perpendicular to the axis of the insertion hole structure is provided on the outside of the insulator, and an insertion hole communicating with the internal cavity of the insulator is vertically formed on the inclined surface. The insertion end of the insertion hole structure is aligned and matched with the insertion hole on the insulator.

[0006] Furthermore, a protruding structure for wrapping the socket structure is provided on the outside of the insulator near the socket structure.

[0007] Furthermore, the end face of the insulator located on the same side as the protruding structure is a horizontal surface used to provide space for mechanical equipment to grasp.

[0008] Furthermore, the insertion end of the socket structure includes multiple socket springs that surround to form the insertion hole. The socket springs are cantilever structures. After the contact is inserted, a fitting gap is left between the inner wall of the cavity that matches the insulator and the socket structure and the outer wall of the insertion end of the socket structure to allow the socket springs to expand outward.

[0009] Furthermore, a pair of parallel connecting plates are provided at the rear end of the insertion hole structure facing the outer side of the blind hole opening, and a straight groove is provided on the insulator for inserting and limiting the connecting plates.

[0010] Furthermore, after the contact is inserted into place, the end of the connecting plate near the inside of the blind hole abuts against the bottom of the straight groove, and the bottom of the straight groove forms an upper fixing platform that limits the inner side of the connecting plate.

[0011] Furthermore, the connecting plate is provided with fixing spring pieces at both ends of the bottom of the straight groove. The fixing spring pieces are cantilever structures, with their fixed ends close to the inner side of the straight groove and their movable ends facing the outer side of the straight groove. In the natural state, the fixing spring pieces are raised and higher than the connecting plate. The side wall of the straight groove is provided with a limiting groove for accommodating the fixing spring pieces. During the insertion of the contact piece, the fixing spring pieces are squeezed by the side wall of the straight groove. After the insertion is in place, the fixing spring pieces move to the limiting groove and return to their original state. The end of the fixing spring pieces facing the outer side of the straight groove abuts against the side wall of the limiting groove near the outer side of the straight groove.

[0012] Furthermore, the insulator is provided with an observation hole that penetrates the wall of the insulator, and the observation hole is connected to a limiting groove in the wall near the observation hole.

[0013] Furthermore, the opening of the straight groove is provided with a chamfer to guide the connecting plate into the straight groove.

[0014] Furthermore, the connecting plate has multiple pins distributed on the end facing outward from the blind hole for insertion into the PCB board.

[0015] Compared with existing technologies, the advantages of this invention are: By adding a socket portion with an angle R to the PCB socket, when a change in the mating angle is required in actual production, this invention can design a socket portion with a corresponding angle based on the specific mating angle. The integrated design of the insulator and contact component's mating and fixing structure simplifies the PCB socket structure and facilitates installation; simply inserting the contact component into the blind hole of the insulator completes the installation of the PCB socket. In summary, this invention can increase the mating angle for two-piece PCB sockets and square sockets, thereby increasing product applicability, simplifying product structure, and reducing assembly costs.

[0016] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] An embodiment of the present invention provides a PCB connector structure with an engagement angle and easy installation, such as... Figures 1 to 14 As shown. In this embodiment, the PCB connector structure is specifically a PCB socket 3, which includes an insulator 1 and a contact 2. The insulator 1 is an integral structure, and the contact 2 is directly inserted into the insulator 1, simplifying the overall structure of the connector and making the installation process simpler and faster. To accommodate the mating angle under special circumstances, based on the existing horizontal mating of the PCB socket and the square socket, an angle R is added to the mating direction of the PCB socket 3 and the square socket 4 in this embodiment, thereby realizing the mating angle R of the PCB socket 3 and the square socket 4 under special circumstances, such as... Figure 10As shown, the square socket 4 is tilted at an angle R. When a plug is inserted into the square socket, it can be tilted at an angle R to adapt to the spatial position of the equipment components in special circumstances. When the PCB socket 3 is inserted into the PCB board 6, the square socket 4 is fixed to the rack by its own square plate 5 and is simultaneously connected to the PCB socket 3. The plug is inserted into the square socket 5 to realize the electrical connection between the plug and the PCB board.

[0035] For ease of explanation, in this embodiment, the side where the PCB socket 3 and the PCB board 6 are inserted is the lower end surface, the other end surface is the upper end surface, the side near the square socket 4 is the front end surface, the other end surface is the rear end surface, and the other two sides are the left end surface and the right end surface, respectively.

[0036] In existing horizontally mating PCB sockets, the insulator includes a housing and a cover plate. The contacts include a socket structure for mating with a square socket and pins for mating with the PCB board. The mating directions of the socket structure and the pins are perpendicular to each other. The housing is a vertically continuous cuboid. The contacts are inserted into the housing from top to bottom, with the lower end of the contacts abutting against a protrusion on the edge of the lower opening of the housing. The pins extend from the lower part of the housing for mating with the PCB board. Then, the cover plate is placed over the housing from top to bottom, thus fixing the contacts inside the housing. The socket structure is aligned with the socket holes on the side wall of the insulator. One end of the square socket passes horizontally through the socket hole and is inserted into the socket structure. The square socket is fixed to the cabinet panel by the square plate. Then, the plug is plugged into the other end of the square socket to achieve electrical connection. The existing technology has many insulator parts, a complex structure, and requires at least two steps for installation, making the installation process relatively complicated. Furthermore, the plug and square socket can only be mated horizontally.

[0037] This invention improves upon existing horizontally mating PCB sockets. In this embodiment, the insulator 1 is a one-piece structure, simplifying the structure by replacing the existing shell and cover plates with a single component, thus reducing manufacturing costs. Insertion holes are provided on the insulator; after the contact 2 is inserted and fixed within the insulator 1, the connector installation is complete, which is simple and quick.

[0038] The insulator 1 is provided with blind holes 111 as insertion holes. The number of blind holes 111 is the same as the number of contacts 1 installed on the insulator 1. In this embodiment, two contacts 1 are inserted into the insulator 2, so two blind holes 111 are arranged side by side on the insulator 1. The opening of the blind hole 111 is located at the bottom of the insulator 1. The upper part of the insulator is closed and the lower part is open, forming a cavity inside to accommodate the contact 2. The contact 2 is inserted into the insulator through the opening of the blind hole.

[0039] A protruding structure 101 is added to the upper end of the insulator 1 near the front side. The front end near the upper side and the protruding structure 101 are inclined to the rear side, forming an inclined surface 104 on the outer side of the insulator. The inclined surface 104 is perpendicular to the mating direction. The insulator at the location of the inclined surface 104 is provided with a vertically penetrating socket 110 into the cavity of the insulator for inserting a square plate socket. The number of contacts 2 is the same as the number of sockets 110. The insertion end of the square plate socket passes through the socket 110 and is inserted into the corresponding contact 2 socket structure inside the insulator. Because the inclined surface 104 has a certain tilt angle, after the square plate socket 4 and the PCB socket 3 are inserted, the matching surfaces of the two are tilted, thereby achieving a certain mating angle as required. The raised structure 101 allows the socket portion of the PCB socket 3 (including the socket 110 on the insulator and the socket structure on the contact) to be raised at an angle when there is a mating tilt. The socket structure of the contact is wrapped by the insulator 1 while being raised. That is, the top of the insulator cavity is tilted to wrap the socket structure of the contact and prevent power leakage.

[0040] The rear end of the protruding structure 101 connects to the upper end face of the rear side of the insulator. The upper end face of the rear side of the insulator is a horizontal surface 103 with a minimum diameter of 7mm (i.e., the minimum dimension in any direction of this surface is 7mm). This horizontal surface 103 provides sufficient space for mechanical equipment to grip, facilitating the gripping of the PCB socket 3 and its installation on the PCB board 6 by mechanical equipment during automated assembly in the factory. The surface on the outer surface of the protruding structure 101 that connects to the horizontal surface is the connecting surface 102. The angle between the connecting surface 102 and the horizontal surface 103 is relatively large, causing the height of the connecting surface 102 from one side of the protruding structure to the horizontal surface 103 to decrease rapidly, reducing the impact on the dimensions of the horizontal surface and ensuring that the gripped area of ​​the horizontal surface 103 is a minimum diameter of 7mm.

[0041] In other embodiments of the present invention, the protrusion structure 101 may be omitted, and the thickness of the top of the insulator may be increased. An inclined, raised cavity may be provided on the top of the insulator, and the front end face of the upper part of the insulator may be formed as an inclined surface. A socket is vertically formed on the inclined surface. After the socket structure of the contact is installed inside the insulator, it is aligned with the socket to achieve mating with the square socket. This solution allows the PCB socket to maintain an overall square shape, facilitating the stacking of PCB sockets together.

[0042] Contact 2 includes a socket structure 203, a connecting plate 204, and pins 202. Contact 2 is manufactured entirely by cutting and bending a strip of material. The upper end of contact 2 is the socket structure 203, which is inclined and raised relative to the horizontal direction to match the position of the socket 110 on the insulator. Simultaneously, the upper half of the socket structure 203 matches the inner wall of the top of the insulator cavity. The insertion end of the socket structure 203 matches the front inner wall of the upper part of the insulator cavity, and the insertion hole of the socket structure 203 aligns with the socket 110. When the square-shaped socket is inserted into the PCB socket, it passes through the socket 110 and inserts into the socket structure 203.

[0043] The plug-in end of the socket structure is a plug-in hole formed by multiple socket springs 205, such as Figure 12 As shown, the socket springs 205 are all arc-shaped cantilever structures. Their fixed ends are located at the rear end of the socket structure, and their movable ends form the insertion ends. The movable ends of the socket springs 205 converge towards their own axis. In this embodiment, the insertion end of the socket structure is formed by four socket springs 205 surrounding it to form a insertion hole. When the insertion end of the square socket is inserted into the socket structure 203, the socket springs 205 expand outwards and clamp the insertion end of the square socket under their own elastic force. Therefore, after the contact 2 is installed inside the insulator 1, a fitting gap 108 is left between the upper outer surface of the socket structure 203 and the inner wall of the top of the insulator cavity. Simultaneously, because the socket structure 203 is inclined upwards, there is space below it, allowing the socket springs 205 at the bottom of the socket structure 203 to expand downwards. The fitting gap 108 and the space below the socket structure 203 combine to leave space for outward expansion when the socket structure is inserted.

[0044] The horizontal cross-section of the blind hole 111 of the insulator 1 matches the cross-section of the socket structure 203 on the horizontal plane, so that the socket structure 203 can be inserted into the blind hole from the opening of the blind hole 111.

[0045] The lower part of the rear end of the socket structure 203 has an opening, and the left and right sides of the opening extend downward to form extension plates 206. The lower ends of the extension plates 206 are respectively provided with connecting plates 204 extending forward and backward, that is, two connecting plates 204 are provided below each socket structure 203. The lower end of the insulator is provided with a straight groove 109 for inserting the connecting plate 204. The opening of the straight groove 109 is located on the lower end face of the insulator and extends upward from the lower end face of the insulator. The inner cavity of the straight groove 109 communicates with the cavity of the corresponding blind hole.

[0046] Each contact has two connecting plates 204, and each blind hole 111 communicates with two corresponding straight slots 109. The front-to-back length of the connecting plate 204 is greater than the front-to-back length of the socket structure. Therefore, the front-to-back length of the straight slot 109 is greater than the front-to-back length of the blind hole 111, and the straight slot 109 is divided into front and back parts by the blind hole 111. The width of the straight slot 109 matches the thickness of the connecting plate 204, and the depth of the straight slot matches the height of the connecting plate 204. The depth of the straight slot is less than the depth of the blind hole 111.

[0047] The straight groove 109 is divided into front and rear parts by the bottom of the blind hole 111. The bottom of the straight groove 109 forms two upper fixing platforms 106 at the front and rear of the insulator. The contact 203 is inserted into the blind hole 111 of the insulator from below. The insertion structure 203 passes through the blind hole. Then, the upper edges of the front and rear ends of the connecting plate 204 abut against the corresponding upper fixing platforms 106, thereby restricting the insertion structure 203 from moving further upward, realizing the positioning of the contact above, and the contact is installed in place.

[0048] Fixed spring pieces 201 are provided at the lower part of both the front and rear ends of the connecting plate 204. The fixed spring pieces 201 are cantilever structures, with their upper fixed ends set on the connecting plate 204 and their lower movable ends. In their natural state, the fixed spring pieces 201 of the insertion hole structure 203 tilt outwards. Two fixed spring pieces 201 are provided on the front and rear sides of each contact member 2. The two fixed spring pieces 201 tilt in opposite directions, both facing outwards. Limiting grooves 113 are provided on the walls of both the front and rear ends of the straight groove 109. The openings of the limiting grooves 113 are located on the side walls of the straight groove 109. Limiting grooves 113 are provided on the front and rear ends of the two straight grooves corresponding to the same blind hole. The two limiting grooves 113 located on the same side in the front-rear direction extend in opposite directions to match the positions of the fixed spring pieces 201. The lower side wall of the limiting groove forms a lower fixed platform 105 for restricting the downward movement of the connecting plate. When the contact 2 is inserted, as the connecting plate passes through the straight groove, the fixing spring 201 is compressed by the side wall of the straight groove. When the fixing spring 201 moves to the limiting groove 113, the limiting groove 113 provides space for the fixing spring 201 to return to its original shape. When the fixing spring 201 returns to its original shape, the contact 2 is installed in place, and the lower end of the fixing spring 201 abuts against the lower fixing platform 105 to achieve positioning of the lower part of the contact.

[0049] The front and rear ends of the connecting plate 204 abut against the front and rear end faces of the straight groove, respectively, to achieve front-to-back positioning of the contact 2. After the connecting plate 204 is inserted into the straight groove 109, the left and right side walls of the connecting plate 204 abut against the side walls of the straight groove 109, thereby limiting the left and right directions of the contact. By limiting the connecting plate in various directions, the contact is fixedly installed inside the insulator.

[0050] One side of the limiting groove communicates with the blind hole, and the front and rear end faces of the straight groove form a platform connection surface 107 connecting the upper fixed platform 106 and the lower fixed platform 105. After the contact 2 is installed on the insulator 1, it is easy to observe from the opening of the blind hole whether the fixing spring 201 is installed in place. Figure 1 As shown.

[0051] The straight groove 109 has a chamfer 115 at the opening on the lower end face of the insulator, which can guide the front and rear ends of the connecting plate and the raised fixing spring 201 into the straight groove 109.

[0052] An observation hole 112 is provided at the front end of the insulator 1. The opening of the observation hole 112 is located on the front end face of the insulator 1. The observation hole 112 is connected to the limiting groove 113 near the front end of the insulator. When the contact is installed in place, the fixing spring 201 is located in the limiting groove 113. The fixing spring 201 can be observed through the observation hole 112, so that during the contact installation process, it is possible to observe whether the contact is installed in place through the observation hole.

[0053] Multiple pins 202 are distributed along the length of the lower end of the connecting plate 204. After the contacts are installed, the pins 202 are located outside the blind holes, allowing for mating with the PCB board. Guide posts 114 are distributed on the insulator between two blind holes. The height of the guide posts 114 extending from the lower end face of the insulator is higher than the height of the pins 202 extending from the lower end face of the insulator. When the PCB socket is inserted into the PCB board, the guide posts 114 are first inserted into the guide holes on the PCB board, and then the pins 202 are guided and inserted into the PCB board.

[0054] The insulator is provided with fixing bosses 116 at its four corners, which are used to insert and fix it to the mounting holes on the PCB board, thereby fixing the PCB socket 3 to the PCB board 6.

[0055] The invention adds a socket portion with an angle R and a corresponding protrusion structure 101 and mating clearance 108 to the PCB socket. In actual production, when a change in the mating angle is required, the invention can design a socket portion with a corresponding angle based on the specific mating angle. The integrated mating and fixing structure of the insulator and contact component simplifies the PCB socket structure and facilitates installation; the PCB socket can be installed simply by inserting the contact component into the blind hole of the insulator. In summary, this invention can increase the mating angle for two-piece PCB sockets and square sockets, thereby increasing product applicability, simplifying product structure, and reducing assembly costs.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
