Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
The electric connector provided by the embodiment of the invention is used for electrically connecting a plurality of connected pieces. For example, as shown in fig. 1, the connected members are two PCB plates, namely a first PCB plate 3a and a second PCB plate 3b, and the electrical connector is used for electrically connecting the first PCB plate 3a and the second PCB plate 3 b.
The electrical connector comprises an insulative housing structure 1 and an electrical contact 2 (as shown in fig. 3A), wherein the insulative housing structure 1 is made of an insulative material, such as a plastic material. Also, in the present embodiment, as shown in fig. 2A, the insulating housing structure 1 includes a housing base 11 and a cover plate 12 which are detachably connected, wherein the housing base 11 is used for fixedly connecting with the first PCB board 3a and the second PCB board 3b, and the housing base 11 has a receiving groove therein capable of receiving the electrical contact 2; the cover plate 12 is used to close the receiving slot opening in the housing base 11, and the first PCB 3a and the second PCB 3b are parallel to each other and located in the same plane and mounted on one side of the cover plate 12. Further, in the cover plate 12, a plurality of openings 121 are provided on the plate surface of the cover plate 12, and as shown in fig. 2B, the plurality of contact portions 22 of the electrical contact 2 extend to the outside of the insulating housing structure 1 through the plurality of openings 121, respectively, so as to be able to electrically contact with the first PCB 3a or the second PCB 3B.
By accommodating the electrical contacts 2 therein by means of the insulating housing structure 1 described above, not only can the space occupation be reduced, the device structure simplified, but also assembly and modularity can be facilitated.
It should be noted that, in the present embodiment, in order to achieve the electrical connection of the parallel and coplanar first PCB 3a and the second PCB 3b, the plurality of openings 121 are all located on the plate surface of the cover plate 12, however, the embodiment of the present invention is not limited to this, and in practical applications, the positions of the respective openings 121 on the housing of the insulating housing structure 1 may be set according to specific needs, for example, at least one opening 121 may also be located on the housing base 11.
It should be noted that, in the present embodiment, the insulating housing structure 1 is composed of the housing base 11 and the cover plate 12, but the embodiment of the present invention is not limited to this, and in practical applications, the insulating housing structure 1 may also be composed of at least two separate bodies of any other structures, or the insulating housing structure 1 may also adopt an integral structure, and the electrical contact 2 is embedded in the cavity of the insulating housing structure 1 by combining with a known technical means.
As shown in fig. 3A, the electrical contact 2 includes a plurality of conductive strips 2a, the plurality of conductive strips 2a being arranged at intervals in the insulative housing structure 1; as shown in fig. 3B, the main body 21 of each conductive strip 2a, which is provided as an electrical contact 2, is provided in the above-mentioned insulating housing structure 1, and the main body 21 of each conductive strip 2a includes a middle section 211 and two edge sections (212a, 212B) located on both sides of the middle section 211, wherein the middle section 211 is provided as a support portion capable of supporting the two edge sections (212a, 212B); the two edge sections (212a, 212b) are bent toward each other with respect to the intermediate section 211 to constitute first bent sections, respectively, and two contact portions (22a, 22b) are formed at ends of the two edge sections (212a, 212b) that are away from the intermediate section 211, respectively.
In the present embodiment, the two contact portions (22a, 22b) are both part of the conductive strip 2a, and are respectively bent with respect to the two edge segments (212a, 212b) to respectively form second bent portions. As shown in fig. 2A, an end of the second bent portion away from the edge segment is located inside the insulating housing structure 1. Thus, the contact portion 22 can be made to have a bent position between both ends thereof for electrical contact with the PCB board, and the contact area is larger than the end portion, so that the contact reliability can be improved.
By supporting the two edge sections (212a, 212b) by means of the middle section 211, the two contact portions (22a, 22b) can be held in a position outside the insulating housing structure 1, while the entire conductive strip 2a can be made resilient by bending the two edge sections (212a, 212b) towards each other with respect to the middle section 211, in particular when pressing the PCB plate against the cover plate 12, the two edge sections (212a, 212b) of the conductive strip 2a are elastically deformed with respect to the middle section 211, so that each contact portion 22 exerts a resilient force on the respective PCB plate against its pressure, i.e. so that both contact portions (22a, 22b) can be brought into resilient contact with the respective PCB plate. The elastic contact can increase the contact matching tolerance between the electric connector and the PCB (perpendicular to the surface direction of the cover plate 12, and the tolerance can reach +/-1 mm), reduce the installation error and improve the installation efficiency.
In the present embodiment, taking the example of electrically connecting the first PCB 3a and the second PCB 3b which are parallel and coplanar, the plurality of openings 121 are arranged on the surface of the cover plate 12 to form two rows of opening sets, and the two rows of opening sets are respectively disposed opposite to the first PCB 3a and the second PCB 3 b. Moreover, each opening 121 in one row of opening groups is aligned in a row corresponding to each opening 121 in the other row of opening groups; the number of the conductive strips 2a is the same as the number of rows of the openings, and two contact portions (22a, 22b) of each conductive strip 2a are provided in one-to-one correspondence with two openings 121 in each row. In this way, both contact portions (22a, 22b) of each conductive strip 2a are used to electrically contact the first PCB board 3a and the second PCB board 3b, respectively, to achieve the electrical connection of the first PCB board 3a and the second PCB board 3 b.
In practical applications, a conductive layer, such as a copper foil layer, is disposed on each PCB board for simultaneously making electrical contact with the contact portion 22 corresponding to at least one opening 121 in the same row of opening sets.
Through setting up a plurality of conducting strips 2a, can increase the contact fit tolerance (be on a parallel with the direction of the face of apron 12 between electric connector and the PCB board, and the tolerance can reach 1mm), reduce installation error, improve the installation effectiveness. In addition, as shown in fig. 3B, for each conductive strip 2a, since it can generate a certain degree of plastic deformation, the size of the included angle a between the two edge sections (212a, 212B) and the middle section 211 can be adjusted, so that the maximum distance that the contact portion 22 extends out of the insulating housing structure 1 can be adjusted to obtain a proper contact acting force, and on the premise that the conductive strip 2a is not subjected to excessive plastic deformation, the purpose of increasing the contact fit tolerance (perpendicular to the plane direction of the cover plate 12, and the tolerance can reach ± 1mm) between the electrical connector and the PCB board is achieved. For example, the maximum distance may be 3mm by adjusting the size of the included angle a.
It should be noted that, in the present embodiment, the electrical contact 2 includes a plurality of conductive bars 2a, but the embodiment of the present invention is not limited thereto, and in practical applications, the electrical contact 2 may also adopt any other structure, for example, the electrical contact 2 is a monolithic structure, such as a single conductive sheet (the width is, for example, the sum of the widths of all the conductive bars 2 a) similar to the structure of the conductive bars 2a described above.
In addition, the conductive bar 2a is suitable for the electrical connection of the first PCB 3a and the second PCB 3b which are parallel and coplanar, and in practical application, along with the change of the layout of the PCBs, or the connected component is a component other than the PCBs, the structure of the electrical contact 2 can be adapted, and the electrical contact 2 has the following structure and function, so as to achieve the object of the embodiment of the present invention, specifically, the electrical contact 2 includes a main body arranged in the insulating housing structure 1 and a plurality of contact portions formed on the main body, and the electrical contact 2 has elasticity, so that each contact portion 22 can elastically contact with the corresponding connected component. Therefore, a connecting structure with two ends of a male end and a female end is not needed, welding and plugging are avoided, and quick connection can be achieved. In addition, since the electrical contact 2 has elasticity so that each contact portion can be in elastic contact with each connected member in a one-to-one correspondence, it is possible to increase the contact fitting tolerance between the electrical connector and the connected member, reduce the mounting error, and improve the mounting efficiency.
It should be further noted that, in the present embodiment, the middle section 211 of the conductive strip 2a is provided as a support portion capable of supporting two edge sections (212a, 212 b); the two edge sections (212a, 212b) respectively form a first bending part, however, the embodiment of the present invention is not limited to this, in practical application, the structure of the supporting part, the structure of the first bending part bending relative to the supporting part and the bending direction can be designed according to specific situations, and in addition, one end of each first bending part far away from the supporting part is formed with the contact part.
In the present embodiment, as shown in fig. 4, a first limit structure for limiting the position of the electrical contact 2 is provided on the inner side surface (e.g., the bottom surface of the receiving groove) of the housing base 11, for example, the first limit structure includes a first limit groove and a plug-in piece formed on the inner side surface of the housing base 11; correspondingly, a limiting part matched with the first limiting groove and an inserting groove inserted with the inserting piece are formed on the main body of the electric contact piece 2. Specifically, as shown in fig. 3B, the first limiting groove is defined by, for example, first protrusions 111a and 111B arranged at intervals; the plug connector is composed of a second lug 111a and a second lug 111b which are arranged on two sides of the first limiting groove; correspondingly, as shown in fig. 3B, a part (for example, the middle section 211) of the main body 21 of the conductive strip 2a is located in the first limiting groove, and two limiting protrusions 24 are respectively disposed on two sides of the main body 21 of the conductive strip 2a, and the two limiting protrusions 24 are used for limiting the first protrusion on the same side with the two limiting protrusions 24, so that the conductive strip 2a can be limited from moving along the first limiting groove. Moreover, insertion grooves 24 are provided on both edge sections (212a, 212b) of the conductive strip 2a for respectively inserting the second protrusion 111a and the second protrusion 111b, so that the conductive strip 2a can be restricted from rotating.
In the present embodiment, as shown in fig. 5, a second limit structure is provided on the inner side surface of the cover plate 12 (the front surface 122 facing away from the cover plate 12), and the first limit structure is used for limiting the position of the electrical contact 2. For example, the second stopper portion includes a second stopper groove 124 formed on the inner side surface of the cover plate 12, and a portion of the main body of the electrical contact 2 is located in the second stopper groove 124. For example, the parts of the two edge sections (212a, 212b) of the conductive strip 2a, which are far from the middle section, are located in the second limiting groove 124.
With the aid of the first limiting structure and the second limiting structure, the situation that the conductive strip 2a is warped when in unilateral contact (namely, only the contact part on one edge section is in contact with the PCB) can be avoided, so that when the two PCBs have a height difference, effective transmission of signals can still be ensured. Of course, in practical applications, any other first and second limiting structures may be adopted as long as the position of the electrical contact 2 can be defined.
In the present embodiment, a plurality of engaging members are provided at intervals on the circumferential side surface of the cover plate 12, and specifically, as shown in fig. 5, for the rectangular cover plate 12, four engaging members 125a having a smaller width are provided on the long side surface thereof, and one engaging member 125b having a larger width is provided on the short side surface thereof. As shown in fig. 6, the snap members 125a and 125b are, for example, wedge-shaped blocks, and the height of the wedge-shaped blocks protruding from the circumferential side surface of the cover plate 12 is smaller toward the inner side of the plate surface of the cover plate 12.
Correspondingly, as shown in fig. 4, a plurality of slots 113 are provided on the inner side surface of the housing base 11, and the clamping members are clamped with the slots 113 in a one-to-one correspondence manner, as shown in fig. 6. When the cover plate 12 is pressed into the housing base 11, the slope of the wedge-shaped block moves along the inner side of the housing base 11 until the wedge-shaped block moves into the slot 113, and at this time, the vertical surface of the wedge-shaped block is matched with the side surface of the slot 113, so that the cover plate 12 cannot be separated from the housing base 11.
The clamping mode of the wedge-shaped block and the clamping groove is not only beneficial to reducing the manufacturing difficulty of the shell base 11 and the cover plate 12, but also simple in structure and reliable in fixation.
In the present embodiment, as shown in fig. 7A, two mounting holes (115a, 115b) and two positioning members (116a, 116b) are provided on a side of the housing base 11 facing away from the cover plate 12 (i.e., the back surface 114 of the housing base 11), and the two mounting holes (115a, 115b) and the two positioning members (116a, 116b) are arranged in a rectangular shape, for example, for a housing base 11 having an approximately rectangular shape, the two mounting holes (115a, 115b) and the two positioning members (116a, 116b) are arranged at four corners of the housing base 11. Wherein two mounting holes (115a, 115b) are diagonally arranged, each mounting hole is used for being fixedly connected with the PCB board through a fastener (such as a screw or a bolt); two positioning members (116a, 116b) are diagonally arranged, each positioning member is used for limiting the position and the direction of the housing base 11 by matching with a positioning structure arranged on a PCB (printed circuit board), the positioning members are positioning columns, and the positioning structure on the PCB is a positioning groove matched with the positioning columns.
Through making two setting elements (116a, 116b) be the diagonal setting, can fix a position the locating position and the direction of casing base 11 fast to can effectively solve the connector and reverse problem and the locating position need not put again, cause the problem of inefficiency.
In the present embodiment, as shown in fig. 7A and 7B, the bosses 117A and 117B are provided on the side surfaces of the housing base 11 where the two mounting holes (115a, 115B) are located, respectively, and as shown in fig. 7B, the bosses 117A and 117B make the contour of the rear surface 114 of the housing base 11 approximately in the shape of an inverted "S", which can further avoid the inversion of the connector, so that the mounting efficiency can be improved.
In summary, the electrical connector provided by the embodiments of the present invention can not only reduce the occupied space and simplify the structure of the device, but also facilitate assembly and modularization by accommodating the electrical contact therein through the insulating housing structure; and, through being formed with a plurality of contact portions on the main part of electrical contact, each contact portion passes each opening one-to-one to extend to the outside of insulating housing structure, each is connected the piece and only need contact each contact portion and can realize the electricity and connect, and need not to adopt connection structure such as having public female both ends again, avoids welding and grafting to can realize quick connection.
