Description

Technical Field

[0001] The utility model relates to the field of electrical connection, and particularly to an integrated board-to-board connector. Background Art

[0002] With the development of communication technology, board-to-board blind plug connectors are widely used in large quantities. Currently, board-to-board blind plug connectors usually have a single-channel structure, which includes a connecting rod, a single-plug escapement end, and a sliding-in end. During use, the escapement end and the sliding-in end are respectively welded to two facing PCB boards. Then, one end of the connecting rod is pre-installed on the escapement end, and the center line of the other end of the connecting rod forms an inclined angle within a 360° inner space angle relative to the center line of the escapement end. When the two PCB boards are brought together within a certain distance range, the connecting rod will be inserted into the sliding-in end to connect the two PCB boards. Its defect lies in that: during the docking process of the two PCBs, the central axes of the escapement end, the connecting rod, and the sliding-in end need to be on the same axis. However, due to processes such as machining and welding, the escapement ends and the sliding-in ends on the two PCB boards are definitely not on the same axis, resulting in the connecting rod being unable to be inserted into the sliding-in end, and the success rate of blind plugging is relatively low. Especially in a multi-connecting-rod multi-channel structure, the inclination directions of the connecting rods in each channel are random, the inclination angles are inconsistent, and even interference may occur between the connecting rods, making blind plugging very difficult to achieve, restricting the development of multi-channel integration, and unable to layout more channels in a limited space. Summary of the Utility Model

[0003] To solve one or more of the above problems, the utility model provides an integrated board-to-board connector.

[0004] According to one aspect of the utility model, the integrated board-to-board connector includes: an integrated fixed seat, an integrated sliding seat, an integrated positioning member, and a plurality of connecting rods;

[0005] The integrated fixed seat is provided with at least two escapement end holes;

[0006] The integrated sliding seat is provided with sliding-in end holes that are front and back opposite to the escapement end holes, and a guiding bowl mouth with a chamfer structure is provided at the outer end of each sliding-in end hole;

[0007] The center distances of a plurality of positioning card holes of the integrated positioning member, the center distances of the escapement end holes, and the center distances of the sliding-in end holes are the same;

[0008] At least two connecting rods have one end inserted into the escapement end holes of the integrated fixed seat, and the positioning card slots in the middle of the outer walls of the connecting rods are clamped with the positioning card holes of the integrated positioning member to form a stable three-dimensional framework. The other ends of all the connecting rods are inserted into the sliding-in end holes of the integrated sliding seat at equal angles and in the same inclination.

[0009] In some embodiments, the inner side surface of the positioning card hole is in an arc shape, and the positioning card slot is an arc-shaped groove.

[0010] In some embodiments, an inlet port for the rod is provided at the outer end of the positioning card hole of the integrated positioning member, so as to form an open structure.

[0011] In some embodiments, external chamfered slopes are symmetrically provided at both ends of each inlet port for the rod.

[0012] In some embodiments, two columns and at least one row of positioning card holes are provided in a rectangular array on the integrated positioning member.

[0013] In some embodiments, the integrated positioning member is an externally closed structure formed by integrally connecting the end heads of a plurality of arc-shaped positioning card holes in a rectangular array. There is a notch between adjacent positioning card holes. Two columns and one row or two columns and two rows of positioning card holes are provided in a rectangular array on the integrated positioning member.

[0014] In some embodiments, when the positioning card hole is an open hole or an arc hole, the arc angle is greater than 270°.

[0015] In some embodiments, the escapement end holes of the integrated fixed seat, the positioning card holes of the integrated positioning member, and the sliding-in end holes of the integrated sliding seat are all arranged in the same rectangular array or linearly arranged at equal intervals.

[0016] In some embodiments, elastic openings are provided in the tube walls at both ends of the connecting rod, and a first insulating sleeve is sleeved in the tube wall hole. A jack member made of a conductive material is sleeved in the inner holes of the two first insulating sleeves;

[0017] A second insulating sleeve is installed in the escapement end hole of the integrated fixed seat, and a first pin fixed in the second insulating sleeve is inserted into the jack member;

[0018] A third insulating sleeve is fixedly provided in the sliding-in end hole at the rear end of the integrated sliding seat, and a second pin fixed in each third insulating sleeve is inserted into the jack member.

[0019] In some embodiments, an inner cut is formed by the intersection between adjacent guide bowl openings.

[0020] The integrated board-to-board connector forms a three-dimensional framework structure by setting an integrated positioning member, with the positioning card holes of the integrated positioning member cooperating with the positioning card slots of each connecting rod, enabling all the connecting rods to be parallel to each other and the other ends of all the connecting rods to have the same inclination angle, achieving successful blind insertion at one time. Its beneficial effects are as follows: First, this solution makes all the connecting rods incline at the same angle, with a high blind insertion success rate and high assembly efficiency, realizing highly integrated multi-channel blind insertion docking, and at the same time avoiding damage to parts caused by poor blind insertion. Second, the center distance of the positioning card holes, the center distance of the escapement end holes, and the center distance of the sliding-in end holes can be minimized, allowing more channels to be set in the same space, achieving high integration. Third, the guiding bowl greatly improves the success rate of one-time blind insertion. This solution can minimize the distance as much as possible. Even if the adjacent part of the guiding bowl is incomplete, the connecting rods inclined in the same direction can still achieve one-time blind insertion, further providing high integration and blind insertion success rate. Fourth, the center distance between the integrated channels is the same as the center distance of the two end seats. As long as the connecting rod of one channel can be inserted into the sliding-in end, the other connecting rods will move synchronously in the direction of the movement of the first connecting rod under the thrust of the snap in the middle of the connecting rod, and finally all will be inserted into the corresponding sliding-in end channel, greatly improving the assembly efficiency.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0035] Figures 1 to 9 An integrated board-to-board connector according to an embodiment of the present invention is schematically shown. As shown in the figure, the integrated board-to-board connector includes: an integrated fixed seat 1, an integrated sliding seat 2, an integrated positioning member 3, and a plurality of links 4;

[0036] The integrated fixed seat 1 is provided with at least two escapement end holes 11;

[0037] The integrated sliding seat 2 is provided with a sliding end hole 21 that is directly opposite to the escapement end hole 11 in the front and rear, and a guiding bowl mouth 22 with a chamfer structure is provided at the outer end of each sliding end hole 21. Preferably, an inner notch 23 is formed by the intersection of adjacent guiding bowl mouths 22. The intersection of the guiding bowl mouths 22 can reduce the spacing of the escapement end holes 11, integrate more links 4 and channels in the same space, and reduce the occupied space of the integrated product.

[0038] The center distances of a plurality of positioning card holes 31 of the integrated positioning member 3, the center distances of the escapement end holes 11, and the center distances of the sliding end holes 21 are the same. Preferably, the escapement end holes 11 of the integrated fixed seat 1, the positioning card holes 31 of the integrated positioning member 3, and the sliding end holes 21 of the integrated sliding seat 2 are all arranged in the same rectangular array or equally spaced linearly.

[0039] A positioning card slot 41 is provided in the middle of the outer wall of the link 4. Among them, the positioning card slot 41 is preferably set as an arc-shaped groove, and the inner side surface of the positioning card hole 31 is preferably set as an arc surface. The arc structure can achieve a good positioning and fitting effect.

[0040] At least two connecting rods 4 are inserted into the escapement end holes 11 of the integrated fixed seat 1 at one end, and the positioning card slots 41 in the middle of the outer wall of the connecting rod 4 are clamped with the positioning card holes 31 of the integrated positioning member 3 to form a stable three-dimensional framework. The other ends of all the connecting rods 4 are inserted into the sliding end holes 21 of the integrated sliding seat 2 at equal angles and in a consistent inclination.

[0041] By setting the integrated positioning member 3, the positioning card holes 31 of the integrated positioning member 3 cooperate with the positioning card slots 41 of each connecting rod 4, thus forming a three-dimensional framework structure, making all the connecting rods 4 parallel to each other, and the inclination angles of the other ends of all the connecting rods 4 being consistent, achieving successful blind insertion at one time. Its beneficial effects are as follows: First, this solution makes all the connecting rods 4 inclined at the same angle, with a high blind insertion success rate and high assembly efficiency, realizing highly integrated multi-channel blind insertion docking, and at the same time avoiding damage to parts caused by poor blind insertion. Second, the center distance of the positioning card holes 31, the center distance of the escapement end holes 11, and the center distance of the sliding end holes 21 can minimize the distance, and more channels can be set in the same space, realizing high integration. Third, the guiding bowl mouth 11 greatly improves the success rate of one-time blind insertion. This solution can minimize the distance as much as possible. Even if the adjacent part of the guiding bowl mouth 11 is incomplete, the connecting rods 4 inclined in the same direction can still achieve one-time blind insertion, further providing high integration and blind insertion success rate. Fourth, the center distance between the integrated channels is the same as the center distance of the two end seats. As long as the connecting rod of one channel can be introduced into the sliding end, the other connecting rods will move synchronously in the direction of the movement of the first connecting rod with the thrust of the buckle in the middle of the connecting rod, and finally will all be introduced into the corresponding sliding end channel, greatly improving the assembly efficiency.

[0042] Furthermore, as Figures 1 to 6 shown, in Embodiment 1, an inlet port 32 is provided at the outer end of the positioning card hole 31 of the integrated positioning member 3, thus presenting an open structure. Preferably, chamfered bevels 33 are symmetrically provided at both ends of each inlet port 32. Preferably, the integrated positioning member 3 is a flat plate structure, and two columns and at least one row of positioning card holes 31 are arranged in a rectangular array on the integrated positioning member 3. Its beneficial effect is that the open structure is convenient for processing, manufacturing and assembly, and can significantly improve the assembly efficiency.

[0043] Furthermore, as Figures 7 to 9 shown, in Embodiment 2, the positioning card hole 31 is an arc hole or a closed card hole; when the positioning card hole 31 is an arc hole, the integrated positioning member 3 is an outer closed structure formed by integrally connecting the ends of a plurality of arc-shaped positioning card holes 31 arranged in a rectangular array, with a gap between adjacent positioning card holes 31, and two columns and one row or two columns and two rows of positioning card holes 31 are arranged in a rectangular array on the integrated positioning member 3. Its beneficial effect is that this structure is simple and has a low processing cost.

[0044] Preferably, in Embodiment 1 and Embodiment 2, when the positioning card hole 31 is an open hole or an arc hole, the arc angle is greater than 270°. The beneficial effect is that this angle can not only reduce the spacing and arrange more channels in the same space, but also maintain a good guiding effect and avoid the reduction of the guiding efficiency due to too small guiding surface.

[0045] Furthermore, elastic openings are provided on the tube walls at both ends of the connecting rod 4. A first insulating sleeve 42 is sleeved in each tube wall hole, and a jack member 43 made of a conductive material is sleeved in the inner holes of the two first insulating sleeves 42. Preferably, a second insulating sleeve 12 is installed in the escapement end hole 11 of the integrated fixed seat 1, a first pin 13 is fixed in the second insulating sleeve 12, and the first pin 13 is inserted into the jack member 43; preferably, a first chamfer 14 is provided outside the escapement end hole 11. Preferably, an integrated outer shell 20 is inserted into the rear end of the integrated sliding seat 2, the end of the integrated outer shell 20 is inserted into the sliding end hole 21, a third insulating sleeve 24 is fixed in the sliding end hole 21, and a second pin 25 is fixed in each third insulating sleeve 24, and the second pin 25 is inserted into the jack member 43. The beneficial effect is that this structure can achieve good plug-in connection and conduction performance.

[0046] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
