Description

Technical Field

[0001] This invention relates to a connector, and more particularly to a vertical double-row integrated connector. Background Technology

[0002] Conventional dual-row connectors are all vertically wired. This type of vertically wired dual-row connector requires more vertical space, which is not conducive to use in small vertical spaces and cannot achieve compact design of electronic products. Therefore, in order to save vertical space, the wiring direction of dual-row connectors has been changed to horizontal. Currently, the terminals and insulation body of common horizontally wired dual-row connectors are connected and positioned by a mushroom head snap-fit ​​method. After frequent plugging and unplugging operations, this snap-fit ​​method will cause the terminals to disengage from the insulation body, resulting in connector failure. Moreover, the assembly structure of this type of terminal and insulation body is assembled by hard plugging, which is inconvenient to assemble, has a high assembly cost, and is prone to defective products. Summary of the Invention

[0003] To overcome the above-mentioned defects, the present invention provides a vertical double-row integrated connector, which reduces the space occupied by the wiring pair, increases the practicality of the product, expands the scope of application, and ensures that the terminals are firmly and stably connected to the insulating body without disengaging even after long-term use.

The pin clamping piece structure of the second metal terminal can pass through the second mounting hole in sequence and extend out of the outside of the second sidewall of the insulating body through the first terminal slot and the first mounting hole. A second limiting insert is formed on the insulating side cover. The second limiting insert can be inserted into the second terminal slot of the insulating body, and the second limiting insert abuts against the surface of the wire clamping spring structure of the second metal terminal facing away from the second inlet hole.

[0011] As a further improvement of the present invention, let the axial dimension of the second metal terminal along the second inlet hole be B1, let the straight-line distance between the opening sidewalls formed by the second mounting hole on the third and fourth sidewalls of the insulating body be B2, and let the vertical distance between the opening sidewall of the mounting hole on the third sidewall of the insulating body and the sidewall of the first mounting hole facing the fourth sidewall be B3. <B1<B2。

[0012] As a further improvement of the present invention, the insulating side cover is provided with a first buckle on the surface of the second sidewall facing the insulating body, and an elastic cantilever structure is provided on the surface of the insulating side cover facing the first sidewall facing the insulating body. The end of the elastic cantilever structure is formed with a second buckle. The first buckle can be inserted into the first mounting hole and is fastened to the side of the first mounting hole near the fourth sidewall of the insulating body.

The cavity is divided into a first terminal slot and a second terminal slot by a partition rib.

[0015] The beneficial effects of this invention are as follows: This invention breaks away from the conventional linear component assembly method. By changing the wiring direction of the double-row connector to two perpendicular directions, it avoids the large space occupied in the vertical direction caused by wiring in a single vertical direction, thereby increasing the practicality of the product and expanding its application range. This invention designs the insulating component as a split structure consisting of an insulating body, insulating side covers, and insulating bottom covers that are snapped together, which facilitates the assembly of metal terminals, reduces assembly costs, and increases assembly efficiency. After the metal terminals, insulating body, insulating side covers, and insulating bottom covers are assembled, they form an integrated structure. The metal terminals are blocked by the side wall of the terminal slot within the insulating body, preventing them from coming out of the insulating body or shifting due to long-term pulling force. The structure is stable and easy to use. Attached Figure Description

[0032] Example: A vertical dual-row integrated connector includes an insulating shell, a first metal terminal 40, and a second metal terminal 50. The insulating shell has a first terminal positioning cavity and a second terminal positioning cavity formed inside. The first metal terminal 40 and the second metal terminal 50 are respectively fixedly positioned within the first terminal positioning cavity and the second terminal positioning cavity. The first metal terminal 40 and the second metal terminal 50 are respectively formed with a wire clamping spring structure and a pin clamping structure. The wire insertion direction of the wire clamping spring structure and the pin insertion direction of the pin clamping structure are perpendicular to each other. The insulating shell first… The first wire inlet hole 106 and the second wire inlet hole 108 are provided parallel to each other on the side wall. The first pin hole 303 and the second pin hole 304 are provided parallel to each other on the second side wall of the insulating shell. The first wire inlet hole 106 and the second wire inlet hole 108 are respectively connected to the wire inlet of the wire clamping spring structure on the first metal terminal 40 and the second metal terminal 50. The first pin hole 303 and the second pin hole 304 are respectively connected to the pin inlet of the pin clamping plate structure on the first metal terminal 40 and the second metal terminal 50. The first side wall and the second side wall on the insulating shell are perpendicular to each other.

[0033] The above structure makes the wiring direction and the pin direction of the double row connector perpendicular to each other, avoiding the problem of large space occupation in that direction caused by the wiring direction and the pin direction of the double row connector being in the same direction. It can be used in more compact products, improving the practicality of the product and expanding its application range.

[0034] The insulating housing includes an insulating body 10, an insulating side cover 20, and an insulating bottom cover 30. A first inlet hole 106 and a second inlet hole 108 are parallel and spaced apart on the first side wall of the insulating body 10. A first mounting hole 103 is provided on the second side wall of the insulating body 10. The extension direction of the first mounting hole 103 is perpendicular to the extension direction of the first inlet hole 106 and the second inlet hole 108. A first terminal slot 109 and a second terminal slot 110 are formed inside the insulating body 10. The first inlet hole 106 communicates directly with the first terminal slot 109, and the second inlet hole 108 communicates directly with the second terminal slot 110. The first mounting hole 103 communicates with both the first terminal slot 109 and the second terminal slot 110. A first metal terminal 40 is inserted into the first terminal slot 109, and a second metal terminal 50 is inserted into the second terminal slot 109. Inside the two-terminal slot 110, the pin clip structures of the first metal terminal 40 and the second metal terminal 50 both extend out of the outer side of the second side wall of the insulating body 10 through the first mounting hole 103. The insulating side cover 20 can be fixedly installed on the insulating body 10. The insulating side cover 20 and the inner side wall of the first terminal slot 109 and the second terminal slot 110 of the insulating body 10 respectively form the first terminal positioning cavity and the second terminal positioning cavity for fixing and positioning the first metal terminal 40 and the second metal terminal 50. The insulating bottom cover 30 can be fixedly installed on the outer side of the second side wall of the insulating body 10. The first pin hole 303 and the second pin hole 304 are provided on the insulating bottom cover 30. The pin clip structures of the first metal terminal 40 and the second metal terminal 50 are respectively inserted into the first pin hole 303 and the second pin hole 304. By designing the insulating shell as a split structure consisting of an insulating body 10, an insulating side cover 20, and an insulating bottom cover 30, the assembly and positioning of the first metal terminal 40 and the second metal terminal 50 are facilitated, improving assembly efficiency and reducing assembly costs. Furthermore, the first metal terminal 40 and the second metal terminal 50 are respectively housed in the insulating first terminal slot 109 and the second terminal slot 110, and are restricted by the side walls of the first terminal slot 109 and the second terminal slot 110. Long-term insertion and removal will not cause the terminals to detach from the insulating body 10. The metal terminals are installed stably and securely, meeting the stability requirements for long-term use of the connector.

[0035] The first metal terminal 40 includes a first terminal body 402, a first clip group 403, a first conductive contact piece 401, and a first spring piece 404. The first terminal body 402 includes a first wire clamping body and a first pin body extending in mutually perpendicular directions. The first clip group 403 is installed at the end of the first pin body. A clamping channel with an elastically expandable gap is formed between the first clip groups 403. The first conductive contact piece 401 is fixedly disposed on the first wire clamping body. One end of the first spring piece 404 is fixedly disposed on the first wire clamping body. The other end of the first spring piece 404 can elastically abut against the first conductive contact surface. The first wire clamping body, the first spring piece 404, and the first conductive contact piece 401 together form the wire clamping spring structure of the first metal terminal 40. The first pin body and the first clip group 403 together form the pin clamping structure of the first metal terminal 40.

[0036] The second metal terminal 50 includes a second terminal body 502, a second clip group 503, a second conductive contact piece 501, and a second spring piece 504. The second terminal body 502 includes a second wire clamping body and a second pin body extending in mutually perpendicular directions. The second clip group 503 is installed at the end of the second pin body, and a clamping channel with an elastically expandable gap is formed between the second clip groups 503. The second conductive contact piece 501 is fixedly disposed on the second wire clamping body. One end of the second spring piece 504 is fixedly disposed on the second wire clamping body, and the other end of the second spring piece 504 can elastically abut against the second conductive contact surface. The second wire clamping body, the second spring piece 504, and the second conductive contact piece 501 together form the wire clamping spring structure of the second metal terminal 50. The second pin body and the second clip group 503 together form the pin clamping structure of the second metal terminal 50. The wire clamping spring structure and the pin clamping plate structure of the first metal terminal 40 and the second metal terminal 50 extend and enter the wire in mutually perpendicular directions, respectively. The wire clamping spring structure clamps and positions the wire by the elastic force between the conductive contact plate and the spring plate. To prevent the spring plate from deforming in the opposite direction when the wire is pulled outward, resulting in failure, a serrated structure can be provided on the surface of the first and second conductive contact plates to block and limit the deformation direction of the elastic deformation end of the spring plate. The wire clamping body and the pin body of the first terminal body 402 and the second terminal body 502 can be formed into a mutually perpendicular integral structure by bending. The clamping plate group can be clamping plates integrally formed on both sides of the pin body by bending. The clamping plates form an elastic clamping mouth to clamp and conduct the pin. In this application, the first metal terminal 40 and the second metal terminal 50 are preferably formed by stamping and bending, resulting in high overall structural strength.

[0037] The size of the first mounting hole 103 on the insulating body 10 is larger than the external dimensions of the wire clamping spring structure of the first metal terminal 40. The first mounting hole 103 is perpendicularly connected to the end of the first terminal slot 109 facing away from the first inlet hole 106. The wire clamping spring structure of the first metal terminal 40 can enter the first terminal slot 109 through the first mounting hole 103, and the wire clamping spring structure of the first metal terminal 40 can be slidably inserted into the first terminal slot 109 along the axial direction of the first inlet hole 106. Inside the first terminal slot 109, the inner side wall and bottom surface of the first terminal slot 109 facing the first inlet hole 106 respectively form a limiting stop surface that matches the shape of the clamping spring structure of the first metal terminal 40. A first limiting insert 204 is formed on the insulating side cover 20. The first limiting insert 204 can be inserted into the first terminal slot 109 of the insulating body 10, and the first limiting insert 204 abuts against the surface of the clamping spring structure of the first metal terminal 40 facing away from the first inlet hole 106. The first metal terminal 40 can be inserted into the insulating body 10 through the first mounting hole 103 and slid into the first terminal slot 109 within the insulating body 10 to the bottom of the first terminal slot 109 for positioning. This structure facilitates the installation of the first metal terminal 40. At the same time, the first metal terminal 40 is blocked by the bottom surface and side wall of the first terminal slot 109 and the side wall of the first mounting hole 103, so it will not detach from the insulating body 10 no matter what force is applied, resulting in high installation stability. In addition, the first metal terminal 40 can also be installed into the first metal slot of the insulating body 10 in other ways. For example, if the side wall of the insulating body 10 corresponding to the opening direction of the first terminal slot 109 is an open structure, the first metal terminal 40 can be directly placed into the first metal terminal slot through the open structure. These are equivalent replacement structures that are easily conceived by those skilled in the art based on this patent and fall within the scope of protection of this patent.

[0038] The insulating body 10 has openings on its third sidewall, which is opposite to the second sidewall, and its fourth sidewall, which is opposite to the first sidewall, respectively, which communicate with the second terminal slot 110. These openings on the third and fourth sidewalls are interconnected to form a second mounting hole 111. The second mounting hole 111 communicates with the first terminal slot 109, the second terminal slot 110, and the first mounting hole 103, respectively. The second metal terminal can be inserted into the insulating body 10 through the second mounting hole 111, and the clamping spring of the second metal terminal 50 is... The structure can be inserted into the second terminal slot 110. The pin clip structure of the second metal terminal 50 can pass sequentially through the second mounting hole 111 and extend out of the outer side of the second side wall of the insulating body 10 through the first terminal slot 109 and the first mounting hole 103. A second limiting insert 206 is formed on the insulating side cover 20. The second limiting insert 206 can be inserted into the second terminal slot 110 of the insulating body 10, and the second limiting insert 206 abuts against the wire clamping spring structure of the second metal terminal 50 at the end surface facing away from the second wire inlet hole 108. The second metal terminal 50 is inserted into the insulating body 10 through the second mounting hole 111 and finally inserted into the bottom of the second terminal slot 110 for positioning. The second metal terminal 50 is easy to install and will not interfere with the first metal terminal 40 during the installation process. In addition, the second metal terminal 50 can also be inserted into the insulating body 10 in other ways. For example, if the side wall of the insulating body 10 and the opening direction of the second terminal slot 110 are open structures, the second metal terminal 50 can be directly inserted into the second metal terminal slot through the open structure. Alternatively, the size of the first mounting hole 103 can be enlarged, and the second metal terminal 50 can also be inserted into the insulating body 10 through the first mounting hole 103. These are equivalent replacement structures that are easy for those skilled in the art to conceive of based on this patent and are within the scope of protection of this patent.

[0039] The first limiting insert 204 and the second limiting insert 206 on the insulating side cover 20 are also provided with pin clamping limit stop ribs 205 respectively. The pin clamping limit stop ribs 205, together with the side walls of the first terminal slot 109 and the second terminal slot 110, clamp the two opposite side wall surfaces of the pin clamping structure of the first metal terminal 40 and the second metal terminal 50.

[0040] The wire clamping spring structure of the first metal terminal 40 and the second metal terminal 50 is firmly fixed within the insulating body 10 by the first terminal slot 109, the second terminal slot 110, the first limiting insert 204 and the second limiting insert 206 on the insulating side cover 20. The root of the pin clamping spring structure of the first metal terminal 40 and the second metal terminal 50 is limited by the side walls of the first terminal slot 109 and the second terminal slot 110 and the pin clamping spring limiting rib 205, ensuring the accurate position of the wire clamping spring structure of the first metal terminal 40 and the second metal terminal 50 after extending out of the first mounting hole 103 of the insulating body 10, facilitating the installation of the insulating bottom cover 30.

[0041] Let the axial dimension of the second metal terminal 50 along the second inlet hole 108 be B1, let the straight-line distance between the opening side walls formed by the second mounting hole 111 on the third side wall and the fourth side wall of the insulating body 10 be B2, and let the vertical distance between the opening side wall of the mounting hole on the third side wall of the insulating body 10 and the side wall of the first mounting hole 103 facing the fourth side wall be B3. The B3 < B1 < B2. This structure enables the smooth assembly of the second metal terminal 50 in the second mounting hole 111, and after being inserted, there will be no phenomena such as the second metal terminal 50 coming out or tilting.

[0042] On the surface of the insulating side cover 20 facing the second side wall of the insulating body 10, there is a first buckle 202. On the surface of the insulating side cover 20 facing the first side wall of the insulating body 10, there is an elastic cantilever structure 203. At the end of the elastic cantilever structure 203, there is a second buckle 201. The first buckle 202 can be inserted into the first mounting hole 103 and stop the first mounting hole 103 from being snap-connected near the fourth side wall of the insulating body 10. On the third side wall of the insulating body 10, there is a side cover limiting slot hole 102 with an opening direction facing the fourth side wall. The elastic cantilever structure 203 on the insulating side cover 20 is inserted into the side cover limiting slot hole 102, and the second buckle 201 is snap-connected to the side wall of the side cover limiting slot hole 102.

[0043] During the assembly of the insulating side cover 20, it only needs to cover the third side wall and the fourth side wall of the insulating body 10, and then the first buckle 202 and the second buckle 201 are respectively snap-connected to the side wall of the mounting hole on one side of the insulating body 10 and the side wall of the side cover limiting slot hole 102. After the snap connection, the insulating side cover 20 is stably connected to the insulating body 10 and is not easily disengaged.

[0044] The inner side of the insulating body 10 is provided with several partitions that are perpendicular to both the first and second side walls. A cavity is formed between two adjacent partitions. The cavity is divided into a first terminal slot 109 and a second terminal slot 110 by a partition rib 107. The vertical distance between the end of the partition rib facing away from the first side wall and the side wall of the first mounting hole 103 away from the first side wall is greater than the axial dimension of the pin clip structure of the second metal terminal 50 along the second inlet hole 108. The inner side of the insulating body 10 is also provided with several terminal limiting ribs. The surface of the several terminal limiting ribs forms a limiting surface that matches the shape of the clamping spring structure of the first metal terminal 40 and the second metal terminal 50. The limiting surface is tightly attached to the outer side wall of the clamping spring structure of the first metal terminal 40 and the second metal terminal 50 to position the clamping spring structure of the first metal terminal 40 and the second metal terminal 50. The outer side of the insulating side cover 20 forms an L-shaped outer surface that can be aligned and spliced ​​with the third and fourth side walls of the insulating body 10 to form an integral part. The above structure can form multiple integrated double-row connector structures, with a robust, stable, and aesthetically pleasing overall structure.

[0045] A countersunk groove structure is formed on the second side wall of the insulating body 10. The first mounting hole 103 is located on the bottom surface of the countersunk groove structure. One end of the insulating bottom cover 30 is fixedly inserted into the countersunk groove structure on the second side wall of the insulating body 10. The outer side wall of one end of the insulating bottom cover 30 is connected and positioned to the inner side wall of the countersunk groove structure on the second side wall of the insulating body 10 by a snap fastener.

[0046] The assembly method of this application is as follows:

[0047] like Figure 6 , 7 As shown in Figure 8, the insulating body 10 is first placed with the inlet hole facing downwards. The first metal terminal 40 is then inserted into the insulating body 10 through the first mounting hole, with a clearance fit. The size A1 of the first mounting hole on the insulating body is greater than the length A2 of the first metal terminal extending axially through the hole. The insertion stops when the clamping spring structure 401 of the first metal terminal touches the partition rib 107 inside the insulating body. The first metal terminal 40 is then pushed downwards until it touches the plastic structure at the bottom of the first terminal slot. In this way, the first metal terminal 40 is initially assembled. Under its own weight, the first metal terminal 40 will not come out or tilt.

[0048] like Figure 9 , 10As shown in Figures 11 and 12, rotate the second metal terminal 50 clockwise to the right, tilting it at a certain angle 'a'. While tilted at angle 'a', insert the second metal terminal 50 into the insulating body 10, ensuring a clearance fit. At this point, the size of the second mounting hole B1 is greater than the length of the second metal terminal 50, B2. Stop when the metal terminal 502 touches the partition rib 107 inside the insulating body. Rotate the second metal terminal counterclockwise around the contact point by angle 'a' to the left, returning it to a horizontal position. Finally, push the second metal terminal 50 downwards until it touches the plastic structure at the bottom of the second terminal slot. The second metal terminal 50 is now initially assembled. Since the size of the insulating body B3 is less than the size of the second metal terminal B2, the second metal terminal 50 will not come out or tilt under its own weight.

[0049] After the initial fixing of the first and second metal terminals is completed, the remaining insulating side cover and insulating bottom cover are assembled and fixed to complete the overall fixing of the product.

[0050] like Figure 13 As shown, when the insulating side cover 20 is pushed down, the second snap 201 of the insulating side cover extends into the snap sliding groove of the side cover limiting slot 102 of the insulating body, and then engages with the snap groove 101 on the side wall of the side cover limiting slot 102. The elastic cantilever structure 203 of the insulating side cover provides a certain engaging force to fix one side of the insulating side cover; the first snap 202 of the insulating side cover engages in the first mounting hole of the insulating body to fix the other side. The snap engagement on both sides can fix the insulating cover 20 to the insulating body 10. The mutual fixation of the two can fix the first metal terminal and the second metal terminal inside the insulating body. The first limiting insert 204 and the second limiting insert 206 of the insulating side cover respectively press and position the first terminal body 402 of the first metal terminal and the second terminal body 502 of the second metal terminal.

[0051] like Figure 14 As shown, when the insulating bottom cover 30 is pushed in to the left, the third locking point 301 and the fourth locking point 302 on the two side walls of one end of the insulating bottom cover respectively cooperate with the first locking point groove 104 and the second locking point groove 105 on the inner side wall of the countersunk groove structure of the second side wall of the insulating body. The cooperation of the third locking point 301 and the fourth locking point 302 can fix the insulating bottom cover 30 to the insulating body 10. The first pin hole 303 on the insulating bottom cover 30

[0052] The first clamp group 403 of the first metal terminal and the second clamp group 503 of the second metal terminal can be secured by the second pin hole 304. This double-row clamp structure can also be fixed by the plastic structure, making it safe and stable to use.
