Description

Connector assembly for PCB combination {connector assembly}

The present invention relates to a new type of connector assembly for coupling PCBs that allows for easy and stable coupling between two adjacent PCBs and enables separation from each other.

Generally, a connector assembly is mainly used in electronic products and is a device used to connect signals or power between two components.

In the case of vehicles, many electrical components are used, and these electrical components are connected with cables to receive various signals or power. At this time, the connector assembly serves to connect or disconnect the cable and the electrical component.

Meanwhile, among the connector assemblies used in vehicles, the board-mounted connector assembly is provided for electrical connection between the PCB and a cable, or between the PCB and another PCB. In relation to this, it is as presented in Patent Publication No. 10-2002-0056351, Publication Patent No. 10-2009-0030888, Publication Patent No. 10-2011-0081360, and Publication Patent No. 10-2018-0123372.

In other words, the connector assembly is mounted directly on the PCB to enable connection between the PCB and the cable, or between two PCBs, rather than between cables.

However, in the case of the above vehicle, there was a problem in that the connector assembly was undesirably separated due to vibration generated during driving or engine operation, or a signal transmission defect occurred due to wear of the contact portion. Accordingly, conventionally, connector assemblies used in vehicles are designed to have a structure that can be firmly coupled.

However, since the connection between the connector assemblies is firmly established as described above, there was a problem in that the connection portion between the connector assembly and the PCB was damaged during the process of separating the connector assembly.

In particular, in the case of a small connector assembly for connecting two PCBs, the separation distance between the two PCBs was narrow (a distance that a finger could not fit into), making it difficult for the worker to hold only the connector. As a result, there was a high risk that the connector would be damaged when the connectors were separated, or that the connection area between the PCB and the connector would be damaged.

Additionally, when the two PCBs are connected, if the separation distance between them is narrow, there is a disadvantage in that it is difficult to check whether the assembly has been completed. As a result, incomplete fastening was frequent and there was a problem of separation between connectors or terminals when driving the vehicle.

As shown in these drawings, the connector assembly for coupling the PCB according to an embodiment of the present invention allows the connector assembly for coupling the PCB that electrically connects the two PCBs 10 and 20 to be firmly coupled and prevent damage when separated. It was made possible.

The connector assembly for coupling a PCB according to an embodiment of the present invention is largely comprised of a first connector 100 and a second connector 200. This is explained in more detail for each component as follows.

First, the first connector 100 will be described with reference to FIGS. 1 to 9 and 10 to 12.

The first connector 100 is a connector mounted on the first PCB 10.

The first connector 100 includes a first body portion 110.

The first body portion 110 is mounted on the upper surface of the first PCB 10 and is formed as a cylinder with an open upper surface and a peripheral wall. The peripheral wall of the first body 110 is formed of a front wall 110a, a rear wall 110b, and both side walls 110c.

A first mounting groove 111 on which a first connection terminal 120, which will be described later, is mounted is formed on the front wall 110a and the rear wall 110b of the first body 110.

The bottom of the first connector 110 is formed to be partially open so that a portion of the first connection terminal 120, which will be described later, protrudes to the outside and can be mounted on the first PCB 10.

Additionally, the first connector 100 includes a first connection terminal 120.

The first connection terminal 120 is a terminal for electrical connection with the first PCB 10. The first connection terminal 120 may be provided as one or in plurality of two or more.

The first connection terminal 120 is formed to be bent in multiple stages, a portion is located in the first mounting groove 111 formed on the inner surface of the first body portion 110, and the other portion is located in the first body portion 110. ) penetrates the bottom and is exposed to the bottom.

Additionally, the first connector 100 includes a guide protrusion 130.

The guide protrusion 130 is formed to protrude upward from the bottom of the first body portion 110 as a component for coupling with the locking member 250 formed on the second connector 200, which will be described later.

The guide protrusion 130 is formed to cross between the front wall 110a and the rear wall 110b of the first body 110. That is, the internal space of the first body portion 110 is configured to provide a coupling space on one side and a coupling space on the other side, respectively, based on the guide protrusion 130, and the one coupling space and the other coupling space include a plurality of coupling spaces. One connection terminal 120 is provided for each.

A reinforcing part 131 having a thicker thickness than other parts is formed on the guide protrusion 130. In other words, the provision of the reinforcing part 131 prevents the guide protrusion 130 from bending and deforming the front wall 110a or the rear wall 110b. At this time, the reinforcement portion 131 is formed to gradually become thicker toward the lower end of the guide protrusion 130.

Locking protrusions 132 are formed on the upper front and rear surfaces of the guide protrusion 130, respectively. The locking protrusion 132 is formed to protrude from the upper front and rear surfaces of the guide protrusion 130, respectively. At this time, the upper surface of the locking protrusion 132 is formed to gradually slope downward toward the end. The locking protrusion 132 may be formed collectively from one side to the other side of the guide protrusion 130, or may be formed partially from one side to the other side of the guide protrusion 130.

Meanwhile, the first connector 100 may further include a first coupling flange 140. The first coupling flange 140 may be provided to mechanically fix the first connector 100 to the first PCB 10. That is, the first coupling flange 140 is provided on one circumferential wall (e.g., both side walls) of the first body portion 110 forming the first connector 100, so that the first connector 100 It can be configured to be firmly fixed to the first coupling flange 140.

Next, the second connector 200 will be described with reference to FIGS. 1 to 9 and 13 to 16.

The second connector 200 is a connector mounted on the second PCB 20.

The second connector 200 includes a second body portion 210.

The second body portion 210 is formed as a cylinder having a peripheral wall.

A second mounting groove 211 is formed on two opposing walls of the second body portion 210, into which a second connection terminal 240, which will be described later, is mounted.

Additionally, the second connector 200 includes insertion portions 220 and 230. The insertion portions 220 and 230 are portions inserted into the first body portion 110 of the first connector 100.

The insertion portions 220 and 230 include a first insertion portion 220 inserted between the front wall 110a and the guide protrusion 130 of the first connector 100, and a rear wall 110b of the first connector 100. ) and a second insertion portion 230 inserted between the guide protrusion 130. At this time, each of the insertion portions 220 and 230 is formed to extend downward from the front and rear sides of the bottom of the second body portion 210.

The first insertion part 220 and the second insertion part 230 are arranged to be spaced apart from each other. At this time, the distance between the two insertion parts 220 and 230 may be greater than the front-to-back thickness of the guide protrusion 130 of the first connector 100.

Seating grooves 221 and 231 in which the lower end of the second connection terminal 240 is seated are formed on the outer surface (front or rear) of each of the insertion parts 220 and 230, respectively.

The lower ends of each insertion portion 220 and 230 are gradually inclined inward toward the end. In this case, the top of the first body portion 110 forming the first connector 100 is gradually inclined inward toward the end. As a result, the coupling between the insertion parts 220 and 230 and the first body part 110 can be smoothly achieved.

Additionally, the second connector 200 includes a second connection terminal 240.

The second connection terminal 240 is a terminal provided to electrically connect the first PCB 10 and the second PCB 20 while conducting electricity with the first connection terminal 120. The second connection terminal 240 may be provided as one or in plurality of two or more.

The second connection terminal 240 is formed to be bent in multiple stages, a portion of which is located in the second mounting groove 211 formed on the inner surface of the second body portion 210, and the other portion of the insertion portion 220, 230. It is seated in the seating grooves 221 and 231 formed on the outer surface. Accordingly, when the insertion portions 220 and 230 of the second connector 200 are inserted and coupled into the first body portion 110 of the first connector 100, the second connection terminal provided to the second connector 200 240 and the first connection terminal 120 provided on the first connector 100 are connected to each other.

Additionally, the second connector 200 includes a locking member 250.

The locking member 250 is structured to prevent unwanted separation between the second connector 200 and the first connector 100 while engaging with the guide protrusion 130 of the first connector 100.

The locking member 250 is formed inside each of the insertion parts 220 and 230 to face the guide protrusion 130. At this time, the locking member 250 protrudes upward from the bottom of the insertion portions 220 and 230, and the inner surface of the outer wall (the front wall of the first insertion portion or the rear wall of the second insertion portion) forming the insertion portions 220 and 230. is formed to be spaced apart and selectively inclined toward the inner direction of the insertion portions 220 and 230 (the direction in which the outer wall is located).

The locking member 250 is formed to gradually become thicker toward the bottom. As a result, it is possible to prevent the locking member 250 from being damaged by frequent coupling operations as much as possible and provide a stronger locking force.

In particular, the vertical height of the locking member 250 is lower than the height of the insertion portions 220 and 230 and higher than half the height of the insertion portions 220 and 230. This structure is intended to prevent damage due to frequent coupling operations by allowing the locking member 250 to undergo sufficient bending deformation.

More specifically, it is preferable that the upper and lower height of the locking member 250 is formed to be more than 2/3 of the height of the insertion portions 220 and 230. As a result, sufficient contact pressure is provided to maintain a stable restraint state, and smooth bending and deformation is possible by the manipulation force of the locking member 250 to release the restraint.

The locking member 250 has restraining protrusions 251 that are caught by the locking protrusion 132 of the guide protrusion 130 and are respectively protruding. The restraining protrusions 251 may be formed on opposing surfaces between the locking members 250, respectively.

The upper surface of the locking protrusion 132 is inclined downward toward the end, and the bottom surface of the restraining protrusion 251 is inclined upward toward the distal end. At this time, the bottom surface of the locking protrusion 132 may be formed as a flat surface, and at least a portion of the upper surface of the restraining protrusion 251 may be formed as a flat surface. Accordingly, when the restraining jaw 251 is restrained by the locking jaw 132, the second connector 200 is prevented from moving upward from the first connector 100.

A manipulation protrusion 252 is formed to protrude on opposing surfaces between the locking members 250 forming each of the insertion portions 220 and 230. The manipulation protrusion 252 is formed to be located on the lower side of the restraining jaw 251.

Meanwhile, a cut groove 112 that opens for manipulation of the locking member 250 is formed on one peripheral wall of the first body portion 110 forming the first connector 100. That is, even though the two connectors 100 and 200 are coupled through the cut groove 112, the manipulation protrusion 252 is visible from the side of the first body portion 110.

For example, cut grooves 112 are formed on both side walls 110c of the first connector 100 so that the manipulation protrusions 252 of each locking member 250 can be seen.

Due to the above structure, the user can use a tool (or a separate dedicated jig) on the side of the first connector 100 to attach the restraining jaw 251 of the locking member 250 to the locking jaw of the guide protrusion 130. 132), it can be manipulated to deviate from it.

In particular, both side walls (wall surfaces visible through the cut groove) of the manipulation protrusion 252 are formed to form an inclined or curved surface so that the width gradually decreases toward the center. For example, the masonry protrusion 252 may be formed to have a semicircular or triangular structure when viewed in plan.

Accordingly, when the manipulation protrusion 252 is pressed using a tool from either side of the first connector 100, the locking member 250 can be tilted in a direction perpendicular to the direction in which the tool is inserted.

The second connector 200 may further include a second coupling flange 260. The second coupling flange 260 may be provided to mechanically fix the second connector 200 to the second PCB 20. That is, the second coupling flange 260 is provided on one peripheral wall (e.g., both side walls) of the second body portion 210 forming the second connector 200, so that the second connector 200 It can be configured to be firmly fixed to the second PCB 20.

Meanwhile, the connector assembly for coupling the PCB may be provided with a structure to prevent incorrect insertion of the second connector 200 back and forth.

For example, a passing protrusion 222 is formed protruding from the lower end of one of the two insertion parts 220 and 230 forming the second connector 200, and is formed on one of the upper front or back sides of the guide protrusion 130. A passing groove 133 may be formed in the locking protrusion 132 formed on the surface to allow the passing protrusion 222 to pass through.

At this time, the passing protrusion 222 is formed to have a protruding distance sufficient to pass through the passing groove 133 formed in the guide protrusion 130 of the first connector 100. That is, the structure of the passage groove 133 and the passage protrusion 222 prevents the second connector 200 from being incorrectly inserted into the first connector 100 with its front and back reversed.

In the following, the coupling process and separation process of the PCB connector assembly according to the above-described embodiment of the present invention will be described.

First, each connector 100 and 200 is provided mounted on each PCB 10 and 20. For example, the first connector 100 is provided mounted on the top of the first PCB 10, and the second connector 200 is provided mounted on the bottom of the second PCB 20.

Although not shown, at least one of the PCBs 10 and 20 may be fixed to a structure (eg, a headlamp of a vehicle, etc.), or both PCBs 10 and 20 may be provided in an unfixed state.

In the above-mentioned initial state, when it is desired to electrically connect the two PCBs 10 and 20, the two connectors 100 and 200 are positioned to face each other. For example, the first connector 100 is located on the lower side and the second connector 200 is located on the upper side of the first connector 100.

Each insertion portion 220 and 230 of the second connector 200 is positioned between the inner surface of the first body portion 110 forming the first connector 100 and the guide protrusion 130, respectively. In particular, the passing protrusion 222 formed on only one of the insertion parts 220 and 230 is positioned to match the passing groove 133 formed on the guiding protrusion 130 of the first connector 200. This prevents the second connector 200 from being incorrectly inserted into the first connector 100 with its front and back reversed.

In this state, each insertion portion 220 and 230 of the second connector 200 is inserted and coupled into the first body portion 110 forming the first connector 100. Accordingly, the first insertion portion 220 is inserted between the front wall 110a and the guide protrusion 130 of the first body portion 110, and the second insertion portion 230 is inserted into the first body portion 110. ) is inserted between the rear wall (110b) and the guide protrusion (130).

In addition, the restraining protrusion 251 of the locking member 250 formed on the first insertion portion 220 is restrained by the locking protrusion 132 formed on the upper front surface of the guide protrusion 130, and the second insertion portion 220 is connected to the locking protrusion 132. The locking protrusion 251 of the locking member 250 formed on the portion 230 is constrained by the locking protrusion 132 formed on the upper rear side of the guide protrusion 130. As a result, each of the insertion parts 220 and 230 can be prevented from being separated from the first body part 110. At this time, the second connection terminals 240 installed in each of the insertion parts 220 and 230 are in contact with the first connection terminals 120 installed in the first body part 110 and are energized.

As described above, when the second connector 200 is coupled to the first connector 100, the engaging member 250 and the guide protrusion 130 cannot be separated from each other and a stable coupling state is maintained. In particular, the locking member 250 has a sufficient length and a structure that gradually becomes thicker toward the bottom, so that the two connectors 100 and 200 can be smoothly coupled, while providing sufficient contact pressure (force provided from the front) to prevent unwanted Separation can be prevented.

In addition, the operator can accurately recognize whether the locking member 250 and the guide protrusion 130 are coupled through the cut groove 112 formed on at least one of the two side walls of the first connector 100. Poor connection between the connectors 100 and 200 can be prevented.

Meanwhile, when the user wants to disconnect the two PCBs 10 and 20 according to his needs, the two connectors 100 and 200 are separated from each other.

In this case, the worker separates the restraining jaw 251 of the stopping member 250 from the stopping jaw 132 of the guide protrusion 130. That is, a tool (e.g., a release-only jig) is inserted through the cut groove 112 formed in the side wall 110c of the first connector 100 to press the manipulation protrusion 252 formed on the locking member 250. At this time, since the manipulation protrusion 252 is inclined toward the center, when a pressing force is applied by the tool, the locking member 250 is inclined toward the outer wall of the insertion portions 220 and 230. As a result, the restraining protrusion 251 of the locking member 250 is separated from the locking protrusion 132 of the guide protrusion 130.

Thereafter, the operator separates the connectors 100 and 200 by pulling them in opposite directions, thereby disconnecting the connectors from each other.

As described above, the connector assembly for coupling the PCB of the present invention is in a stable coupling state due to engagement between the locking member 250 and the guide protrusion 130 (engagement between the locking protrusion and the restraining protrusion) caused by the coupling between the two connectors 100 and 200. is maintained.

In particular, in the case of the locking member 250, it has a sufficient length and has a structure that gradually becomes thicker toward the bottom, so that it can be stably engaged with the guide protrusion 130.

In addition, the connector assembly for coupling the PCB of the present invention allows separation between the two connectors (100, 200) using a tool even if the gap between the two PCBs (10, 20) is narrow, so that when separating the two connectors (100, 200), the PCB (10, 20) or damage to the connectors 100 and 200 can be prevented.

In addition, in the connector assembly for coupling a PCB of the present invention, a cut groove 112 is formed on the side wall of the first connector 100 for manipulating the locking member 250, so that there is a gap between the locking member 250 and the guide protrusion 130. Connection can be visually confirmed, and connection failures can be prevented.

In the above, even though all the components constituting the embodiment according to the present invention have been described as being combined or operated in combination, the present invention is not necessarily limited to this embodiment. That is, as long as it is within the scope of the purpose of the present invention, all of the components may be operated by selectively combining one or more of them. In addition, terms such as “include,” “comprise,” or “have” described above mean that the corresponding component may be present, unless specifically stated to the contrary, and therefore do not exclude other components.
