Description

Board-to-board connector combinations

The invention relates to a board-to-board connector combination, in particular to a board-to-board connector combination used to electrically connect two circuit boards.

In order to cope with increasingly complicated electronic systems, electronic circuits often adopt modular designs according to different functions, characteristics or requirements, and these multiple electronic circuit modules with different functions need to be able to transmit electronic signals to each other. In this case, each electronic circuit module needs to be provided with connectors that are connected to each other, and these connectors can be electrically connected to each other to achieve the purpose of transmitting electronic signals or power. These electronic circuit modules are often able to be set on different carriers, such as circuit boards, so these connectors must be set on these carriers or circuit boards, respectively, and the electronic circuits on the circuit board carrier are electrically connected through these connectors. In order to form a complete demand circuit, these connectors are generally called board to board connectors.

For example, a car may include an electronic system consisting of an air conditioning system module, a wireless communication module, an engine ignition module, and a central control module. These modules usually reach electricity through board-to-board connectors or cables. Sexually connect and transmit electronic signals. Because the electronic system must withstand continuous thermal shocks caused by continuous vibration and temperature differences when the car is running, and even accidental impact from external forces, board-to-board connectors are likely to be used in harsh environments.

The movable portion of the second terminal of the second connector is formed such that the size in the thickness direction is larger than the size in the width direction, so that it can be elastically deformed in the width direction of the connector. Therefore, the movable portion can be formed in an enlarged cross section, thereby allowing the allowable current value of each terminal to be increased, which is different from the setting of a connector in which the movable portion can be sufficiently elastically deformed in the front-rear direction and width direction of the connector .

The purpose of the present invention is to propose a board-to-board connector combination, in order to improve the convenience of matching operations on the production line, and to make the two connectors have sufficient contact force between the terminals when the two connectors are mated. Each terminal of the two connectors remains electrically connected in a severe environment.

The first connector has a first insulating shell and a plurality of first terminals, and the first insulating shell has a side wall with a plurality of terminal slots. Each of the first terminals is respectively housed in the plurality of terminal slots, each of the first terminals has an interference portion, a bent portion, and a contact portion, and each of the first terminal bent portions elastically extends out of the terminal slot, and The first terminal interference portions, the bent portions, and the contact portions are not aligned on the same straight line.

The second connector has a second insulating shell and a plurality of second terminals. The second insulating shell has a side wall and a tongue plate spaced from each other. Each of the second terminals has a contact portion exposed from the surface of the side wall or the tongue plate, and the tongue or side wall of the second insulating casing is disposed at a corresponding position of the bent portion of the first terminal. When the two connectors are matched, the second connector tongue plate or side wall forces each of the first terminal bent portions to elastically deform, and each of the first terminal contact portions is driven by each of the bent portions to face each of the second terminal contact portions. Displacement.

By using the above-mentioned means, the forward force applied between each of the first terminals and each of the second terminals is increased to achieve the purpose of ensuring that the terminals of the two connectors are maintained in an electrically connected state.

In the disclosure of the description of the present invention, the word "interference" means that two objects that are in contact with each other have frictional force on the contact surfaces of the two objects. This friction may be caused by the two objects having inconsistent appearance dimensions on the contact surface, or it may be caused by one object being buried / molded in another object. Therefore, the means of forming "interference" between two objects in the disclosure of the specification of the present invention may be exemplified by the contact surface between the two objects due to bearing a positive force or due to insert molding.

In the disclosure of the description of the present invention, the two connectors can transmit electronic signals to each other through the electrical connection relationship established by the first terminal and the second terminal after the matching is completed. Among them, "electronic signal" refers to electronic signals in a broad sense, including but not limited to power signals, grounding, identity signals, or high-frequency electronic signals.

In the following disclosure of the present invention, a floating circuit board-to-circuit board connector is taken as an example. The "floating" connector refers to a pair of mating connectors, and at least one of the connectors has a A characteristic that moves within a certain range. The implementation of the floating type circuit board to the circuit board connector is used as an example for exposing the technology of the present invention, and the technology disclosed in the present invention is not applicable to the floating type circuit board to circuit board connector.

As shown in FIGS. 1 to 4, the board-to-board connector combination 10 disclosed in the first embodiment of the present invention is mainly composed of the first connector 100 and the second connector 200 arranged on different circuit boards 310 and 320. The electrical connection relationship is established by matching, and the electronic circuits on the two circuit boards 310 and 320 can communicate electronic signals with each other through the electrical connection relationship. The first connector 100 and the second connector 200 shown in FIG. 1 can be mated with each other and can transmit electronic signals to each other, and the first connector 100 and the second connector 200 shown in FIG. 2 are the aforementioned two. The state before the match (un-mating). As shown in FIG. 1 and FIG. 2, when a circuit board (not shown in FIG. 1 and FIG. 2) having the second connector 200 is located on the XY plane, the first connector 100 is substantially along the Z-axis direction and The second connector 200 is matched or separated.

In the first embodiment of the present invention, the first connector 100 includes a first insulating housing 110 and a plurality of first terminals 120. The second connector 200 corresponds to the first connector 100. The second connector 200 also has a second insulating housing 220 and a plurality of second terminals 230. In order to simplify the following disclosure of the present invention, if any part of the first connector 100 and the second connector 200 use the same name, if there is no special description, it means that the part has the same or similar part with the part with the same name of another connector Features.

The first insulating housing 110 has a base portion 111 and a boss 112 extending from the base portion 111. The boss 112 defines a receiving space 1101 by two opposite side walls 1121, and each side wall 1121 has a row of terminal grooves. 130. Each of the terminal grooves 130 respectively receives a first terminal 120, and the first terminals 120 and the first terminal grooves 130 are respectively arranged along the Y direction. In this embodiment, each of the adjacent terminal grooves 130 is separated by a partition wall 1301, and each of the terminal grooves 130 is penetrated on both sides, that is, one side and side of each of the terminal grooves 130 adjacent to the receiving space 1101. The other surface outside the wall 1121 penetrates each other, so that at least a part of the material of each of the first terminals 120 can extend from either side of each of the terminal grooves 130.

In this embodiment, each of the first terminals 120 has a contact portion 121, a bent portion 122, and an interference portion 123, and each of the first terminal 120 interference portions has an interference relationship with the first insulating housing 110. (Interference), so that the interference portion 123 of each of the first terminals 120 can be fixed to the positioning of the first insulating case 110 by means of embedding. For example, the interference portions 123 of the first terminals 120 in the two rows of the terminal grooves 130 of the first insulating housing 110 are respectively fixed to two insulating blocks 114, and each of the first terminals 120 is secured by each of the insulating blocks 114. An insulating block 114 is formed in each of the terminal grooves 130, or an interference portion 123 of each of the first terminals 120 is formed by embedding and injecting means. In this embodiment, the means for fixing the interference portions 123 of the first terminals 120 to the insulation blocks 114 may include partially puncturing the insulation blocks 114 with the interference portions 123 of the first terminals 120. Or, an insulating block 114 is formed on most of the interference portions 123 of the first terminals 120 by means of buried injection molding, so that each of the interference portions 123 of the first terminals 120 and the first insulating housing 110 have an interference relationship.

The contact portions 121 of each of the first terminals 120 are used to form an electrical connection relationship with each of the second terminals 230 of the second connector 200, thereby transmitting electronic signals to each other. In this embodiment, in an initial free state, the contact portions 121 of each of the first terminals 120 are housed in each of the terminal-receiving grooves 130, and each of the contact portions 121 of the first terminals 120 belongs to an elastic force. Flexible terminal. In the first embodiment of the present invention, each of the terminal grooves 130 is penetrated on both sides, and each of the first terminal 120 contact portions 121 has an elastic deformation capability. Therefore, each of the first terminal 120 contact portions 121 is in a free state or In a deformed state, the contact portions 121 of the first terminals 120 do not necessarily have to be retained in the terminal grooves 130.

Each of the first terminal 120 bent portions 122 is a bent portion between each of the interference portions 123 and the contact portions 121, so that each of the first terminal 120 bent portions 122 deviates from a connection line between each of the interference portions 123 and the contact portions 121, that is, The interference portions 123, the bent portions 122, and the contact portions 121 of the first terminals 120 are not aligned on the same straight line. Since the terminal grooves 130 of each of the first insulating cases 110 are penetrated on both sides, the bent portions 122 of each of the first terminals 120 can extend at least partially from each of the terminal grooves 130. In this embodiment, each of the bent portions 122 of the first terminals 120 is respectively extended from the terminal groove 130 into the receiving space 1101.

Each of the first terminals 120 further includes an end portion 124. The end portion 124 extends from the contact portion 121 of the first terminal 120 in a direction away from the bent portion 122. In addition, each terminal groove 130 of the first insulating housing 110 is provided with The stopper 113 is connected to each of the partition walls 1301. Each stopper 113 has a function of protecting the size of the end portion 124 of each of the first terminals 120 to ensure that the size of the end portion 124 of each of the first terminals 120 is not affected by improper external forces. When the first terminal 120 is free or deformed by force, whether each of the end portions 124 contacts or only approaches the stopper 113 depends on the stress requirements of the first terminals 120 in specific cases. For example, if each stopper 113 is in contact with the end portion 124 of each first terminal 120, each stopper 113 applies a reaction force to the end portion 124 of each first terminal 120, so that each first terminal 120 contact portion 121 may The two-terminal 230 contact portion 231 outputs a larger forward force.

Each of the first terminals 120 further includes a fixing portion 125. The fixing portion 125 extends from the interference portion 123 in a direction away from the bending portion 122, and further extends out of one side of the first insulating housing 110. The first connector 100 is fixed at On the circuit board 310, the fixing portions 125 of the first terminals 120 are soldered to corresponding metal contacts (not shown) on the circuit board 310.

The second insulating housing 220 of the second connector 200 has a pair of side walls 221 spaced apart from each other, and a tongue plate 222 between the two side walls 221. The two side walls 221 of the second insulating case 220 are respectively disposed opposite to the side walls 1121 of the first insulating case 110. When the first connector 100 and the second connector 200 are matched with each other, the two side walls 221 of the second insulating housing 220 are located outside the two side walls 1121 of the first insulating housing 110, and the second insulating shell The tongue plate 222 of the body 220 is accommodated in the receiving space 1101 of the first insulating case 110. At this time, the distance between the side wall 221 and the tongue plate 222 of the second insulating case 220 is slightly larger than the first connector. 100 side walls 1121 allow the terminal grooves 130 on each side wall 1121 of the first insulating case 110 to enter the space between the side wall 221 and the tongue plate 222 of the second insulating case 220.

The second terminals 230 of the second connector 200 are arranged along the Y direction, and each of the second terminals 230 has a contact portion 231, a connection portion 232, and a fixing portion 233. Each of the second terminal 230 contact portions 231 is disposed on the surface of the two side walls 221 of each of the second insulating cases 220, and each of the second terminal 230 fixing portions 233 is fixed to the circuit board 320 and communicates with the circuit. The electronic circuits on the board 320 form an electrical connection state. Each of the second terminal 230 connection portions 232 connects the second terminal 230 contact portion 231 and the fixing portion 233.

Since the contact portions 231 of the second terminals 230 are disposed on the two surfaces of the two side walls 221 facing the tongue plate 222, this configuration can be achieved by technical means such as puncture or buried injection molding. A part of the contact portion 231 of the two terminals 230 is embedded in the side wall 221. However, in this embodiment, the contact portions 231 of the second terminals 230 are used to form an electrical connection with the contact portions 121 of the first terminals 120, and the contact portions 231 of the second terminals 230 are at least partially exposed. Because of the surface of each of the side walls 221, the contact portions 231 of the second terminals 230 are portions that do not have elastic deformation capability.

The purpose of exposing the contact portions 231 of each of the second terminals 230 from the surface of each of the side walls 221 is to enable the contact portions of each of the second terminals 230 to form an electrical connection relationship with the appropriate first terminal 120. The second terminal 230 contact portion 231 is recessed on the surface of any side wall 221, but at least part of the surface of the second terminal 230 contact portion 231 is not covered by an insulating material, so that the first terminal 120 may form mechanical contact with the contact portion 231 The contact portion 231 of the second terminal 230 is partially exposed from the surface of the side wall 221.

Since the bent portions 122 of each of the first terminals 120 at least partially extend out of each of the terminal slots 130 and enter the receiving space 1101 of the first insulating housing 110, when the first connector 100 and the second connector 200 are matched, Each bent portion 122 of each of the first terminals 120 is restricted by the tongue plate 222 of the second insulating case 220 and is elastically deformed. When the bent portions 122 of each of the first terminals 120 are elastically deformed, the interference portion 123 of each of the first terminals 120 is still restricted by the first insulating housing 110, so each of the bent portions 122 of the first terminals 120 can only be driven The contact portions 121 of the first terminals 120 are displaced away from the receiving space 1101 of the first insulation case 110. At this time, the contact portions 121 of the first terminals 120 are forced to approach the side walls 221 of the second insulation cases 220.

Since the contact portions 121 of the first terminals 120 are forced to approach the side walls 221 of the second insulating housing 220, and the second terminals 230 are arranged on the second side of the side wall 221 of the second insulating housing 220 facing the tongue plate 222 Surface, the forward force applied by each first terminal 120 contact portion 121 to each second terminal 230 contact portion 231 increases, regardless of whether the forward force value of each first terminal 120 before the curved portion 122 is elastically deformed is zero or In addition, the forward force between each of the first terminal 120 contact portions 121 and the second terminal 230 contact portions 231 increases accordingly.

In the first embodiment of the present invention, the second insulating housing 220 is positioned on the circuit board 320 only through the fixing portions 233 of the second terminals 230, and the connecting portions of the second terminals 230 may be linearly stressed. Or twisted or deformed, so that the position of each of the second insulating cases 220 relative to the circuit board 320 is uncertain, that is, the second insulating case 220 is fixed to the circuit board 320 in a floating manner. In order to make the position of the second insulating casing 220 relative to the circuit board 320 more stable, a first embodiment of the present invention provides an insulator 210 outside the second insulating casing 220, and fixes the insulator 210 to the circuit The positioning of the plate 320 limits the range in which the second insulating housing 220 can float.

In this embodiment, the connecting portion 232 of each second terminal 230 includes an elastic region 2321 and two interference regions 2322. The two interference regions 2322 of each second terminal 230 are located at both ends of the elastic region 2321, and the two interference regions 2322 of each second terminal 230 have an interference relationship with the insulator 210 and the second insulating case 220. As described above, the two ends of each of the second terminals 230 are respectively fixed to the insulator 210 and the second insulating case 220 by the frictional force caused by the interference relationship. The elastic regions 2321 of each second terminal 230 are located between the insulator 210 and the second insulating housing 220. In this embodiment, each of the elastic regions 2321 has a range of compression and torsional elastic deformation capabilities. The second insulating housing 220 is floating relative to the insulator 210 and the circuit board 320 through the elastic region 2321. For example, when the second insulating housing 220 moves in the X direction relative to the insulator 210, the elastic region 2321 undergoes a bending moment to cause a bending elastic deformation; when the second insulating housing 220 moves in the Y direction relative to the insulator 210 The elastic region 2321 undergoes a torsion and generates twisted elastic deformation. These fluctuations are limited by the sizes of each of the second terminals 230 and the insulators 210 and the second insulating housing 220.

In the first embodiment of the present invention, the insulator 210 has an opening 211 and an intermediate groove 212. The dimensions of each portion of the insulator 210's intermediate groove 212 are slightly larger than the external dimensions of the second insulating housing 220, so that the second insulation The housing 220 can move relative to the insulator 210 to a limited extent. The opening 211 of the insulator 210 is in communication with the intermediate groove 212, so that the first connector 100 can be matched with the second connector 200 through the opening 211.

As shown in FIG. 5, in this embodiment, each of the fixing portions 233 extends from the insulator 210 and is soldered to the circuit board 320. Therefore, the insulator 210 is restricted to the positioning on the circuit board 320. The second connector 200 further includes a fixing plate 240 made of metal. The fixing plate 240 includes two legs 241 and a limiting section 242, and the limiting section 242 is located between the two legs 241. Part of the two legs 241 of the fixing plate 240 are embedded in the insulator 210, and the two legs 210 extend a part of the material outside the insulator 210, so that the fixing plate 240 can be soldered to the circuit board 320, thereby The holding strength of the circuit board to the insulator 210 of the second connector 200 is improved.

In this embodiment, a part of the material of the second insulating case 220 is pressed by the fixing plate 240, so as to restrain the second insulating case 220 so that the second insulating case 220 cannot be separated from the circuit in a direction perpendicular to the circuit board 320. Board 320 and insulator 210. Similarly, those skilled in the art can also use any part of the fixing plate 240 to set a limit on the free displacement range of the second insulating housing 220.

When assembling circuit boards 310 and 320 on the production line, the relative position of the second insulating housing 220 and the insulator 210 is floating, so that the first and second connectors 100 and 200 need not be precisely aligned to make the first An insulating case 110 is matched with the second insulating case 220. In addition, the movable characteristics of the second insulating housing 220 can also reduce the impact of external vibration and shock environment on the matching of the first and second connectors 100 and 200. The elastic deformation of the elastic region 2321 of the second terminal 230 absorbs stress caused by vibration and impact, so that the first and second connectors 100 and 200 have a reliable electrical connection relationship.

6 and 7 disclose a board-to-board connector combination 10a according to a second embodiment of the present invention. The main difference between this second embodiment and the first embodiment lies in the structure of the first terminals 120a, 120 and the second terminals 230a, 230. Configuration. In the second embodiment, the contact portion 231a of the second terminal 230a, the elastic region 2321a and the interference region 2322a of the connection portion 232a, and the structure of the fixed portion 233a and the contact portion 231 of the second terminal 230, and the elastic region 2321 of the connection portion 232 The structures corresponding to the interference region 2322 and the fixing portion 233 correspond to each other. The main difference between this second embodiment and the first embodiment is that in the second embodiment, the contact portions 231a of the second terminal 230a are arranged on the tongue plate 222 opposite to the two surfaces.

In the second embodiment, since the bent portions 122a of each of the first terminals 120a extend at least partially from each of the terminal grooves 130 and protrude from the outside of the boss 112 of the first insulating housing 110, when the first connection When the connector 100 and the second connector 200 are matched, each of the bent portions 122 of the first terminal 120 is restricted by the side wall 221 of the second insulating housing 220 and is elastically deformed.

When the bent portion 122a of each of the first terminals 120a is restricted by the side wall 221 to be elastically deformed, the interference portion 123a of each of the first terminals 120a is still restricted to the first insulating housing 110, so each of the first terminals The contact portion 121a of the 120a can only be displaced in a direction close to the center of the receiving space 1101 of the first insulating case 110. At this time, the contact portion 121a of each of the first terminals 120a is forced to approach the tongue plate 222 of the second insulating case 220. Since the contact portions 121a of the first terminals 120a are forced to approach the tongue plate 222 of the second insulating housing 220, and the contact portions 231a of the second terminals 230a are arranged at two opposite sides of the tongue plate 222 of the second insulating housing 220 Surface, the forward force applied by each first terminal 120a contact portion 121a to each second terminal 230a contact portion 231a increases, causing each first terminal 120a contact portion 121a and each second terminal 230a contact portion 231a to Contact can be more stable.

FIG. 8, FIG. 9 and FIG. 10 disclose the board-to-board connector combination 10 b according to the third embodiment of the present invention. The following disclosure mainly focuses on the differences between the third embodiment and the second embodiment. The first connector 100 of the board-to-board connector assembly 10b is fixed to the circuit board 310 (see FIG. 10), and the second connector 200 is fixed to the circuit board 320b. The main difference between the third embodiment and the second embodiment disclosed in the present invention is that the second connector 200 of the board-to-board connector combination 10b does not have an insulator, and the tongue of the second insulating housing 220 of the second connector 200 The board 222b is a common board with the circuit board 320b, that is, the tongue plate 222b is a part that belongs to the edge of the circuit board 320b. In this embodiment, the second connector 200 is fixed to the edge of the circuit board. The attachment or fixing is a straddle mount method to fix the edge of the circuit board. At this time, the second insulating shell The body 220 is located on two opposite surfaces of the circuit board 320b at the same time, and the second insulating housing 220 surrounds the tongue plate 222b formed by the edge portion of the circuit board 320b. At this time, the tongue plate 222b is located on both sides of the second connector 200. Between walls 221.

In addition, each second terminal 230b of the second connector 200 may be formed by an electronic circuit (trace) on the circuit board. Therefore, each second terminal 230b does not have a connection portion or a fixing portion, and each of the second terminals 230b The contact portions 231b may be a circuit pad or a golden finger, respectively.

As shown in FIG. 10, the first terminal 120a of the third embodiment is similar to the first terminal 120a of the second embodiment, and the interference portion 123a of each first terminal 120a is fixed in the first insulating housing 110, and The first insulation case 110 is fixed to the circuit board 310, and the first terminal 120 a is a corresponding contact soldered to the circuit board 310. When the first connector 100 and the second connector 200 are matched with each other, the bent portion 122a of each first terminal 120a is restricted by the side wall 221 and elastically deformed, so that the contact portion 121a of each first terminal 120a is forced to approach each of the first The tongue plates 222b of the two insulating cases 220, and the forward force applied by the contact portions 121a of the first terminals 120a to the contact portions 231b of the second terminals 230b increases. In addition, since the tongue plate 222b is a part of the circuit board 320b, when the first connector 100 and the second connector 200 are matched with each other, the circuit board 320b and the circuit board 310 are perpendicular to each other. Among them, FIG. 10 is a state where the first connector 100 and the second connector 200 of the board-to-board connector combination 10b are matched with each other, and the state where the first connector 100 and the second connector 200 are separated from each other and related principles can be referred to Relevant descriptions and drawings of the first and second embodiments.

In the foregoing third embodiment of the present invention, the tongue plate 222b belongs to a range where the circuit board 320b is surrounded by two side walls 221. This is because in the disclosure of the third embodiment, each of the first connector 100 The first terminal 120a applies a reinforced positive force from two opposite sides of the tongue plate 222b. Therefore, the third embodiment requires the arrangement of the two side walls 221 to strengthen the positive force. However, when those skilled in the art apply the technology disclosed in the present invention to the implementation of limited space, some or all of the first terminals 120a that need to be reinforced with forward force can be concentrated on the same surface of the tongue plate 222a. The second connector only needs one side wall 221 to reinforce the forward force, and the range of the tongue plate 222a is about the corresponding range of the circuit board 320b facing the side wall 221.

According to the embodiment of the board-to-board connector combination of the present invention, the board-to-board connector combination can maintain stable electrical connection in harsh environments, and allows the production line to have a wide tolerance range, thereby improving the production line. Efficiency in matching operations.
