Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.

Referring to fig. 1, fig. 1 is a schematic view illustrating a first structure of a board-to-board connector according to an embodiment of the present disclosure. Board-to-Board Connectors (BTB Connectors) 100 include a first connector housing 120 and a second connector housing 140.

Referring to fig. 2 and 3, fig. 2 is a first structural diagram of a first connecting socket in the board-to-board connector shown in fig. 1, and fig. 3 is a first structural diagram of a second connecting socket in the board-to-board connector shown in fig. 1. The first connector 120 includes a first base 122, and a conductive plate 124 and a first engaging portion 126 are disposed on the first base 122.

The second connecting seat 140 includes a second base 142, the second base 142 is provided with a conductive elastic sheet 144 and a second clamping portion 146, the second clamping portion 146 is used for connecting with the first clamping portion 126, and when the first clamping portion 126 is connected with the second clamping portion 146, the conductive elastic sheet 144 is used for electrically connecting with the conductive sheet 124.

The first connecting seat 120 and the second connecting seat 140 are connected by the first clamping portion 126 and the second clamping portion 146, the conductive sheet 124 of the first connecting seat 120 and the conductive elastic sheet 144 of the second connecting seat 140 are electrically connected, the conductive sheet 124 and the conductive elastic sheet 144 do not need to be physically connected, the conductive sheet 124 and the conductive elastic sheet 144 are simple in structure, pins with pin-like complex structures in the related art do not need to be adopted, the conductive sheet 124 and the conductive elastic sheet 144 with simple structures can be manufactured by barrel plating of the conductive sheet 124, good consistency and yield can be obtained, the conductive sheet 124 and the conductive elastic sheet 144 are not prone to plating leakage and plating loss, the conductive performance of the conductive sheet 124 and the conductive elastic sheet 144 is good and stable, and the electrical connection of the board to the board connector 100 is stable.

It should be noted that, in the board-to-board connector in the related art, the pins (pin pins) of the first connection seat and the second connection seat are required to be physically and electrically connected, and therefore, the pins need to have sufficient elasticity and relatively complicated shapes, which causes great processing difficulty in the pin stamping process and difficulty in controlling the forming size and precision. In addition, due to the requirement on the contact impedance of the pin, the pin needs to be electroplated, and the complex structure of the pin monomer is poor in compatibility through a barrel plating mode. In the barrel plating process, the pins with complex structures can be buckled into knots, so that the redox reaction of ions in the electroplating process is shielded, and the conditions of plating leakage and plating shortage are caused. Therefore, the thickness of the metal on the surface of the pin can not meet the requirement of environmental reliability, and the risk of disconnection of the pin caused by separation of the plating layer can exist. First connecting seat 120 and second connecting seat 140 in this application implementation are connected through special first joint portion 126 and second joint portion 146, conducting strip 124 and electrically conductive shell fragment 144 only need the butt realize electric connection can, need not realize the physical connection, simple structure, convenient preparation and electrical property are good.

It is understood that the conductive sheet 124 may be a copper foil or other metal sheet, and the conductive elastic sheet 144 may be an elastic conductive sheet 124, for example, one end of the conductive elastic sheet 144 is fixedly connected to the second base 142, and the other end of the conductive elastic sheet 144 is suspended as a free end. Because the conductive sheet 124 and the conductive elastic sheet 144 have simple structures, the conductive sheet 124 and the conductive elastic sheet 144 can be manufactured by continuous plating besides barrel plating, the production efficiency of the continuous plating is far higher than that of the barrel plating, and the consistency and the stability are better than those of the barrel plating.

The first clamping portion 126 may include a protrusion 127, and the second clamping portion 146 may include a clamping groove 147, wherein the clamping groove 147 is used for clamping and fixing with the protrusion 127. It can also be understood that the first connection holder 120 and the second connection holder 140 are connected by the snap-fit fastening of the protrusion 127 and the snap groove 147. The first connecting seat 120 and the second connecting seat 140 can be conveniently clamped or separated by clamping and fixing the protrusion 127 and the clamping groove 147, and the conducting strip 124 and the conducting elastic sheet 144 are not affected in the clamping or separating process.

It should be noted that, in the board-to-board connector in the related art, the pins of the first connection seat and the second connection seat are mated in a snapping manner, so as to implement physical connection and electrical connection. In the process of disassembling in the conditions of maintenance or detection and the like, the stress required to be separated is on the axial line of the first connecting seat and the second connecting seat, otherwise, the pin is influenced by the oblique pulling force, so that the pin is broken and deformed. One back in first connecting seat and the second connecting seat links to each other with the flexible circuit board through the steel benefit, is dismantling the process for the picture convenience, can directly drag the flexible circuit board and drive first connecting seat and the separation of second connecting seat, and the soft or hard that can directly lead to flexible circuit board and steel benefit meets the district and tears. Pin micro-fracture or flexible circuit board micro-crack.

In the embodiment of the present application, the first connection seat 120 and the second connection seat 140 are connected by the clamping connection of the protruding portion 127 and the clamping groove 147, the clamping connection and the separation are both very convenient, the protruding portion 127 and the clamping groove 147 are not damaged, the clamping connection and the separation are performed for a plurality of times, the conductive sheet 124 and the conductive elastic sheet 144 are not affected, the electrical connection performance is stable, and the first connection seat 120, the second connection seat 140 and the corresponding flexible circuit board are not affected.

Specifically, please refer to fig. 4, fig. 4 is another angle structure diagram of the first connecting seat in the board-to-board connector shown in fig. 1. The first base 122 includes a first substrate 123, two ends of the first substrate 123 are both provided with a baffle 128, the conductive sheet 124 is disposed on the first substrate 123 and located between the baffles 128 at two ends of the first substrate 123, the baffles 128 protrude from the first substrate 123, and the protruding portion 127 is disposed on the baffles 128.

The second base 142 includes a second substrate 143, two ends of the second substrate 143 are both provided with a clamping plate 148, the conductive elastic piece 144 is disposed on the second substrate 143 and located between the clamping plates 148 at two ends of the second substrate 143, the clamping plate 148 protrudes out of the second substrate 143, and the clamping slot 147 is disposed on the clamping plate 148.

The protrusion 127 on the blocking plate 128 and the slot 147 on the engaging plate 148 are engaged and fixed, the blocking plate 128 protrudes from the first base plate 123, and the engaging plate 148 protrudes from the second base plate 143, so that the first connecting seat 120 and the second connecting seat 140 can be engaged or separated conveniently.

It is understood that the blocking plates 128 at both ends of the first substrate 123 may be provided with the protrusions 127, and the clamping plates 148 at both ends of the second substrate 143 are also provided with the clamping slots 147. The protrusion 127 may be provided on the baffle 128 at only one end of the first substrate 123, and the engaging groove 147 may be provided on the engaging plate 148 at only one end of the second substrate 143.

For better clamping, the side of the protrusion 127 that fits into the slot 147 may be beveled, and the side of the protrusion 127 that exits the slot 147 may be flat or otherwise shaped.

For better separation, the side of the protrusion 127 that exits the slot 147 may be beveled, and the side of the protrusion 127 that snaps into the slot 147 may be flat or otherwise shaped.

For better engagement and disengagement, the side of the protrusion 127 that engages the slot 147 may be beveled, as may the side of the protrusion 127 that exits the slot 147.

To better mate with the protrusion 127, the shape of the slot 147 may be adapted to the protrusion 127, such that the inner surface of the slot 147 is formed in a shape that is substantially the same as the outer surface of the protrusion 127. The shape of the slot 147 may also be other shapes, such as U-shaped.

Two ends of the second substrate 143 are further provided with side baffles 149, the clamping plate 148 is located between the conductive elastic piece 144 and the side baffles 149, the side baffles 149 are located on the outermost side of the second substrate 143, the side baffles 149 are provided with through holes 1492, push rods 1494 are arranged in the through holes 1492, the push rods 1494 penetrate through the through holes 1492 and are connected with the clamping plate 148, and the push rods 1494 are used for driving the clamping plate 148 to deviate from or move towards the conductive elastic piece 144, so that the baffle 128 located between the side baffles 149 and the clamping plate 148 is clamped with or separated from the clamping plate 148. It can be understood that the two ends of the second base plate 143 are provided with a clamping plate 148 and a side baffle 149 adjacent to each other, the baffle 128 of the first base 122 is clamped between the clamping plate 148 and the side baffle 149, and the clamping plate 148 is driven by the push rod 1494 to clamp or separate the clamping groove 147 on the clamping plate 148 with or from the protrusion 127 on the baffle 128, so as to realize the clamping or separating of the first connecting seat 120 and the second connecting seat 140.

A first elastic member 152 is disposed between the adjacent latch plate 148 and the side guard 149, and the first elastic member 152 is configured to apply a force to the latch plate 148 toward the adjacent side guard 149. It can be understood that, two ends of the second base plate 143 are respectively provided with an adjacent clamping plate 148 and a side baffle 149, a first elastic member 152 is arranged between the clamping plate 148 and the side baffle 149 at one end of the second base plate 143, after the baffle 128 of the first connecting seat 120 is clamped between the clamping plate 148 and the side baffle 149, the first elastic member 152 is elastically deformed, and the elastic deformation restoring force of the first elastic member 152 applies a force to the clamping plate 148 towards the baffle 128, so that the protruding portion 127 of the first connecting seat 120 is clamped with the clamping groove 147 of the second connecting seat 140, and is not easily released. The first elastic member 152 may be provided at both ends of the second substrate 143, or the first elastic member 152 may be provided at only one end of the second substrate 143. One first elastic member 152 may be disposed between the clamping plate 148 and the side blocking plate 149 at either end of the second substrate 143, or a plurality of elastic members may be disposed. When a plurality of elastic members are disposed between the clamping plate 148 and the side blocking plate 149, the plurality of elastic members may be disposed on one side of the clamping groove 147 of the clamping plate 148, or disposed on two sides or around the clamping groove 147 of the clamping plate 148.

When the first elastic member 152 is not elastically deformed, a gap is formed between the adjacent snap plate 148 and the side blocking plate 149, and the gap is smaller than the width of the blocking plate 128. After the baffle 128 of the first connecting seat 120 is clamped between the clamping plate 148 and the side baffle 149, the gap between the clamping plate 148 and the side baffle 149 is increased, the first elastic component 152 generates elastic deformation, the elastic deformation restoring force of the first elastic component 152 acts on the side baffle 149, the side baffle 149 has a force towards the baffle 128, and the clamping groove 147 of the side baffle 149 and the protruding part 127 of the baffle 128 can be stably clamped and fixed. The first elastic member 152 may be a spring or other elastic element.

The second base 142 further includes a back stop 145, and when the locking slot 147 is locked with the protrusion 127, the back stop 145 abuts against the stop 128.

The back baffle 145 of the second base 142 may assist in defining the position of the baffle 128 of the first connector housing 120. For example, one end of the blocking plate 128 abuts against the blocked plate 128, and then the blocking plate 128 moves downward (i.e., toward the first substrate 123), so that the protrusion 127 of the blocking plate 128 can be conveniently snapped into the snap groove 147 of the snap plate 148. For another example, one end of the blocking plate 128 is clamped between the side blocking plate 149 and the clamping plate 148 from the side far from the back blocking plate 145, and then the blocking plate 128 moves toward the back blocking plate 145 until abutting against the back blocking plate 145, because of the elastic stress of the conductive elastic sheet 144, the protruding portion 127 of the blocking plate 128 can be conveniently clamped into the clamping groove 147 of the clamping plate 148.

The back barrier 145 may connect the side barriers 149 at both ends of the second base 142. The number of the back baffles 145 may be 2, and each back baffle 145 is connected to only one side baffle 149 and extends toward the clamping plate 148 to abut against the baffle 128 of the first connecting seat 120.

Because of the existence of the first elastic component 152, the distance between the clamping plate 148 and the side baffle 149 is very small, in order to better insert the baffle 128 of the first connecting seat 120 between the clamping plate 148 and the side baffle 149, an inward force (i.e. a pressure towards the conductive elastic piece 144) can be firstly applied to the push rods 1494 on the two outer sides of the second connecting seat 140, so that the gap between the clamping plate 148 and the side baffle 149 connected with the push rods 1494 is gradually increased until the gap between the clamping plate 148 and the side baffle 149 is larger than the width of the baffle 128 or the limiting part 1496 of the push rod 1494 is abutted by the side baffle 149 and cannot move continuously. The blocking plate 128 of the first connecting seat 120 is then inserted into the gap between the snap plate 148 and the side blocking plate 149 until the first connecting seat 120 abuts against the back blocking plate 145 of the second connecting seat 140. Then, the push rod 1494 is released, the first elastic member 152 is rebounded, and the protrusion 127 of the first connection seat 120 is matched with the slot 147 of the second connection seat 140. After the protrusion 127 of the first connector 120 is inserted into the slot 147 of the second connector 140, the first connector 120 and the second connector 140 will not move in series along the vertical direction of the engaging plate 148 due to the elastic stress (elastic deformation restoring force) of the first elastic member 152; due to the protrusion 127, the locking groove 147 and the back baffle 145, the first connecting seat 120 and the second connecting seat 140 do not move in the direction parallel to the locking plate 148 (including the direction perpendicular to the back baffle 145 and the direction perpendicular to the second base plate 143), i.e., the first connecting seat 120 and the second connecting seat 140 do not move in any direction (i.e., three-dimensional direction) due to the above-mentioned structure. The protruding portion 127 of the first connecting seat 120 and the locking groove 147 of the second connecting seat 140 are completely ensured to be in a close alignment fit state. It should be noted that the locking may be performed in other manners, for example, the first connecting seat 120 is abutted against the back stop plate 145 and then moved toward the second substrate 143 until the protrusion 127 and the locking groove 147 are matched. The embodiment of the present application does not limit the connection manner of the first connection holder 120 and the second connection holder 140, and all connection manners based on the structures of the first connection holder 120 and the second connection holder 140 are within the scope of the embodiment of the present application. Because the first connecting seat 120 and the second connecting seat 140 of the embodiment of the application are in alignment insertion and are not in press fit matching, the assembly difficulty is low, the reliability is high, the risk of pin breakage and virtual buckling caused by inaccurate pre-alignment and improper press fit speed in the press fit matching process is eliminated, and the reliability of the product is improved.

It can be understood that, in the process of clamping the first connecting seat 120 and the second connecting seat 140, the conductive elastic piece 144 is pressed downward toward the second substrate 143, and after the first connecting seat 120 and the second connecting seat 140 are fixed, the conductive elastic piece 144 is elastically deformed, so as to generate an elastic deformation restoring force, so that the conductive elastic piece 144 is stably abutted to the conductive sheet 124, thereby achieving a stable electrical connection.

Referring to fig. 5, fig. 5 is a schematic view of another angle structure of the second connector receptacle in the board-to-board connector shown in fig. 1. One end of the push rod 1494 is fixedly connected with the clamping plate 148, the other end of the push rod 1494 is provided with a limiting part 1496, and the size of the limiting part 1496 is larger than that of the through hole 1492. The push rod 1494 and the clamping plate 148 can be fixedly connected through bonding, fixing and connecting, screwing, fixing and connecting, integral forming and the like. In order to prevent the push rod 1494 from integrally penetrating through the through hole 1492 of the side baffle 149, the other end of the push rod 1494, which is located outside the side baffle 149, is provided with a limiting part 1496, the size of the limiting part 1496 is larger than that of the through hole 1492, the limiting part 1496 cannot penetrate through the through hole 1492, and the push rod 1494 cannot penetrate through the through hole 1492 of the side baffle 149 in the process of driving the snap plate 148 through the push rod 1494. In addition, because the size of the clamping plate 148 is larger than the through hole 1492, the limiting part 1496 also limits the moving distance of the clamping plate 148, so that the baffle 128 of the first connecting seat 120 can be conveniently clamped between the clamping plate 148 and the side baffle 149, and the user can conveniently clamp and separate the first connecting seat 120 and the second connecting seat 140. The limiting part 1496 and the push rod 1494 can be integrally formed and can also be fixedly connected in a screwing way, an adhesion way and the like.

It should be noted that, because the first elastic member 152 is disposed between the side blocking plate 149 and the clip plate 148, the first elastic member 152 can limit the position of the clip plate 148, and one end of the push rod 1494 is fixedly connected with the clip plate 148, in some embodiments, the other end of the push rod 1494 may not be provided with the limiting portion 1496, and the push rod 1494 can be prevented from integrally passing through the through hole 1492 by the first elastic member 152.
