In general, a printed circuit board (PCB) is formed in a layered structure of conductors and insulators in the form of a board, and serves to electrically connect various circuit components (e.g., semiconductors, capacitors, resistors, etc.).

A plurality of contact points are formed on the printed circuit board (PCB), and to each of these contact points, a conductor (wire) for signal transmission is directly connected (e.g., soldered, etc.), another contact point or connection terminal is connected, or a wire The connected PCB direct connection connector is configured to be connected directly.

The PCB direct connection connector can be divided into a single-sided contact structure that is connected to only one side of the printed circuit board, and a double-sided contact structure that is simultaneously connected to both sides of the printed circuit board. At this time, the PCB direct connection connector with the double-sided contact structure can be applied to applications where a current of 3A or less to 15A or more is used based on one copper foil location on the printed circuit board. In other words, the PCB direct connection connector with a double-sided contact structure can increase the limit of current specifications and can be used for more diverse purposes.

It is a structure formed by bending in multiple directions. Accordingly, when an external force is applied in the opposite direction between the two grippers and the connection portion (edge, bent portion) between the gripper and the contact spring is deformed, there is a problem in which the contact spring cannot perform its function due to the deformation of the bent portion.

Moreover, in the terminal of the prior art document 3 described above, there is a problem in that the contact spring is damaged during the bending operation or the accurate bending is not achieved because the number of work steps required to bend the area where the contact spring is formed in multiple stages from the surface of the gripper.

As shown in these drawings, the connector for direct PCB connection according to an embodiment of the present invention largely includes a connector housing 100 and a plurality of terminals 200. In particular, the contact spring 232 forming the contact portion of each terminal 200 is configured to be protected by the two side wall covers 233 and 234.

The PCB direct connection connector according to this embodiment of the present invention will be described for each configuration as follows.

The connector housing 100 of the PCB direct connection connector according to an embodiment of the present invention will be described.

The connector housing 100 is a component that forms the exterior of the PCB direct connection connector.

The connector housing 100 is formed as a block structure.

Here, a PCB insertion groove 110 is formed on the front of the connector housing 100 to allow the PCB 10 to be inserted and coupled thereto.

Additionally, terminal insertion grooves 121 and 122 are formed on the back of the connector housing 100 to allow the terminal 200 to be inserted and coupled thereto.

The terminal insertion grooves 121 and 122 may be provided alone or in plurality of two or more.

Here, some of the terminal insertion grooves (hereinafter referred to as “first terminal insertion grooves”) 121 are contacts that require the use of a relatively high current among the contacts 11 and 12 formed in the PCB 10. A terminal 200 for connection to (11) is inserted and installed.

At this time, the front portion of the first terminal insertion groove 121 is formed to communicate with the inside of the PCB insertion groove 110. That is, the contact springs 232 of the two contact parts 230 forming the terminal 200 installed in the first terminal insertion groove 121 are arranged to be exposed from the top and bottom surfaces of the PCB insertion groove 110, respectively. When the PCB 10 is inserted into the PCB insertion groove 110, the contact point 11 of the PCB 10 and the terminal 200 can be connected to each other.

In addition, the other terminal insertion grooves (hereinafter referred to as “second terminal insertion grooves”) 122 require the use of a relatively low current among the contact points 11 and 12 formed on the PCB 10. A terminal 200 is provided for connection with the contact point 12. A plurality of such second terminal insertion grooves 122 may be provided.

Additionally, a restraining protrusion 130 is formed within the connector housing 100 to protrude into the first terminal insertion groove 121.

The restraining protrusion 130 is restrained by a restraining hole 231a formed in the contact portion 230 of the terminal 200, which will be described later, and acts to prevent the terminal 200 from being separated.

Next, the terminal 200 of the PCB direct connection connector according to an embodiment of the present invention will be described with reference to the attached FIGS. 6 to 10.

The terminal 200 is a component provided to electrically connect the wire 20 and the PCB 10.

The terminal 200 includes a wire connection portion 220 formed at one end of the base 210, and a contact portion 230 having a contact spring 232 at the other end of the base 210.

This is explained in more detail for each component as follows.

First, the base 210 is a part provided to form the body of the terminal 200. That is, the wire connection portion 220 and the contact portion 230 forming the terminal 200 are configured to be provided at both ends of the base 210, respectively.

An uneven portion 211 is formed on the surface of the base 210 to reinforce strength. At this time, the concavo-convex portion 211 may be formed as a single concave portion or protrusion, or may be formed as a plurality of concave portions or protrusions.

In particular, the concavo-convex portion 211 is provided on the connection portion of the base 210 with the contact portion 230, which will be described later, so that during the molding operation of bending the contact portion 230 from the base 210 in multiple stages, the base 210 ) so that the strength can be strengthened.

Next, the wire connection portion 220 is a portion provided for connecting the wire 20. That is, the wire 20 may be connected to and fixed to the wire connection portion 220.

The wire connection portion 220 extends from one end of the base 210. For example, the wire connection portion 220 extends to the rear of the base 210.

The wire connection portion 220 includes one or more barrels 221 and 222 for holding the wire 20.

The barrels 221 and 222 may include a first barrel 221 surrounding the metal conductor 21 of the wire 20 and a second barrel 222 surrounding the covering 22 of the wire 20. there is. To this end, the second barrel 222 may be formed to be longer than the first barrel 221, and the first barrel 221 may be formed to have a wider width than the second barrel 222.

Next, the contact portion 230 is a portion that is directly coupled to the PCB 10 and conducts electricity to the contact point 11 of the PCB 10.

The contact portions 230 are formed as a pair, and the two contact portions 230 are positioned to face each other with the base 210 between them.

In addition, one of the two contact portions 230 is located on the upper side of the first terminal insertion groove 121 formed in the connector housing 100 and is exposed to the upper side of the PCB insertion groove 110, and The other contact part of the contact parts 230 is located on the lower side in the first terminal insertion groove 121 formed in the connector housing 100 and is exposed to the lower side in the PCB insertion groove 110.

That is, as the PCB 10 is inserted between the two contact parts 230, the contact spring 232 of each contact part 230 is brought into contact with each contact point 11 of the PCB 10.

Additionally, the two contact portions 230 are formed to extend from both sides of the base 210, respectively.

In particular, the two contact portions 230 are formed to have a stepped surface from the surface of the base 210. That is, the surface of the contact portion 230 and the surface of the base 210 are not located on the same horizontal line but are formed to have a height difference from each other.

Each of the contact portions 230 includes a bottom member 231, a contact spring 232, and two side wall covers 233 and 234.

Here, the bottom member 231 is a part that forms the upper surface of the contact part 230 located on the upper side or the bottom surface of the contact part 230 located on the lower side when inserted into the connector housing 100.

The floor member 231 is formed to have a surface oriented perpendicular to the surface provided by the base 210. That is, the floor member 231 and the base 210 are arranged perpendicular to each other.

The contact spring 232 is a portion connected to the contact point 11 of the PCB 10.

The contact spring 232 extends in the longitudinal direction of the floor member 231 and is bent to have a set angle. That is, the contact spring 232 is bent from the tip of the bottom member 231 and is elastically deformed toward an area facing the bottom member 231. At this time, a protruding end 232a is formed at the end of the contact spring 232, which additionally protrudes (or is bent) toward the contact point 11 to improve contact with the contact point 11.

The two side wall covers 233 and 234 are parts that protect the contact spring 232 from both directions.

The two side wall covers 233 and 234 are bent from both sides of the floor member 231 and are formed to block both sides of the contact spring 232.

One of the two side wall covers 233 and 234 (hereinafter referred to as “first side wall cover”) 233 is positioned to connect one side of the base 210 and one side of the floor member 231 to each other. It is formed to block one side of the contact spring 232. Among the two side wall covers 233 and 234, the other side wall cover (hereinafter referred to as “second side wall cover”) 234 is connected to the other side of the floor member 231 and blocks the other side of the contact spring 232. is formed

At the same time, as shown in the attached FIG. 10, the two side wall covers 233 and 234 are positioned to be stepped from the base 210. That is, the surface formed by the first side wall cover 233 and the second side wall cover 234 is formed to be stepped from the surface formed by the base 210. In particular, the surface formed by the first side wall cover 233 is formed to be stepped from the surface formed by the base 210.

The step structure between the side wall covers 233 and 234 and the base 210 is a structure that allows the work for forming the side wall covers 233 and 234 to be performed accurately.

That is, when the forming portion of the side wall covers 233 and 234 and the forming portion of the base 210 are formed to be located on the same plane, the bending mold (not shown) stably grips the forming portion of the side wall covers 233 and 234. Failure to do so may cause a problem in which the plate-shaped terminal (terminal plate) 201 moves in the horizontal direction.

In consideration of this, the surface formed by the first side wall cover 233 is formed to be stepped from the surface formed by the base 210 so that the bending mold can be positioned between the two side wall covers 233 and 234, thereby forming the first side wall cover ( In the state in which 233) is formed, it is possible to bend the second side wall cover 234 in the same direction as the first side wall cover 233. That is, since the bending mold can be maintained supported on the side of the first side wall cover 233, the terminal plate 201 is prevented from flowing in the horizontal direction during bending molding of the second side wall cover 234, This makes it possible to accurately form the second side wall cover 234.

Meanwhile, stopper protrusions (232b) are formed to protrude on both sides of the contact spring 232, and stopper grooves (233a, 234a) are provided on the two side wall covers (233, 234) to limit the downward distance of the stopper protrusions (232b). This indentation is formed. That is, the structure of the stopper protrusion 232b and the stopper grooves 233a and 234a can prevent the contact spring 232 from being pressed beyond a set distance.

In the following, the process of manufacturing the terminal 200 of the PCB direct connection connector according to the embodiment of the present invention described above will be described with reference to FIGS. 11 to 16 attached.

First, prepare a flat metal terminal plate 201 for manufacturing the terminal 200. At this time, the terminal plate 201 is made of a conductive metal capable of conducting electricity.

In addition, through a punching operation, a portion for forming the base 210, a portion for forming the bottom member 231, a portion for forming the contact spring 232, and two side wall covers ( 233,234) are formed separately. At this time, various openings or incisions are formed in the terminal plate 201 at each part for forming each barrel 221 and 222 or forming each bent part. This is as shown in attached Figure 11.

The portion for forming the bottom member 231, the portion for forming the contact spring 232, and the portion for forming the two side wall covers 233 and 234 are symmetrical to each other with respect to the portion for forming the base 210. Each is formed as much as possible.

In addition, a restraining hole 231a is formed in the area for forming the bottom member 231, and a stopper protrusion 232b is formed in the area for forming the contact spring 232, and the two side wall covers ( Stopper grooves 233a and 234a are formed in areas for forming 233 and 234, respectively.

Next, a first bending operation to form a first side wall cover 233 is performed on the terminal plate 201.

The first bending operation vertically bends the first side wall cover 233 downward from both sides of the base 210 and simultaneously bends the floor member 231 from the first side wall cover 233 to the base 210. It is performed by bending in a horizontal direction. By this first bending operation, the floor member 231 and the base 210 are in a stepped state. This is as shown in attached FIG. 12.

Next, a second bending operation is performed to form the contact spring 232 on the metal sheet.

The second bending operation is performed by bending the tip of the floor member 231 vertically upward. This is as shown in attached Figure 13.

In particular, when the second bending operation is performed, additional forming (bending or punching) is performed on the tip of the floor member 231, and a protruding end 232a may be provided at the end of the contact spring 232. Let it happen.

Next, a third bending operation is performed to form the second side wall cover 234 on the terminal plate 201.

The third bending operation is performed by bending the second side wall cover 234 vertically upward from the side of the floor member 231. While the third bending operation is being performed, a bending mold is provided between the side wall surface of the first side wall cover 233 and the area for forming the second side wall cover 234, thereby performing the third bending operation. This allows the bending of the second side wall cover 234 to be performed stably and accurately. This is as shown in attached Figure 14.

Next, a fourth bending operation is performed to bend the contact spring 232 to be positioned between the two side wall covers 233 and 234.

While the fourth bending operation is in progress, the stopper protrusions 232b formed on both sides of the contact spring 232 and the stopper grooves 233a and 234a formed on the two side wall covers 233 and 234 engage with each other. Excessive deformation of the contact spring 232 can be prevented. This is as shown in attached Figure 15.

Next, a fifth bending operation is performed to position the two contact portions 230 to face each other.

The fifth bending operation is performed by bending the connection portion between the base 210 and the first side wall cover 233 perpendicularly from the base 210. This is as shown in attached Figure 16.

Afterwards, although not shown, work is performed to form each barrel of the wire connection part. Of course, each of the barrels 221 and 222 may be formed together while any one of the above-described first to fifth bending operations is performed, or may be performed in advance before performing the first bending operation.

Accordingly, the manufacturing of the terminal 200 of the PCB direct connection connector according to the embodiment of the present invention is completed by sequentially performing each of the above-described processes.

Next, the process of installing the terminal 200 of the PCB direct connection connector in the connector housing 100 according to an embodiment of the present invention will be described.

First, connect each wire 20 to the terminal 200.

That is, the metal conductor 21 of the wire 20 is located in the first barrel 221 of the wire connection part 220 forming the terminal 200, and the covering 22 is located in the second barrel 222. In this state, the wire 20 can be fixed to the terminal 200 by bending and deforming each barrel 221 and 222 and compressing them. At this time, the metal conductor 21 of the wire 20 is energized in the first barrel 221.

Next, the terminal 200 to which the wire 20 is connected is inserted and coupled into the terminal insertion groove 121 of the connector housing 100.

The two contact parts 230 forming the terminal 200 are positioned facing each other up and down and are inserted into the first terminal insertion groove 121. At this time, since the two contact portions 230 are formed in a structure that is symmetrical to each other, it does not matter even if the upper and lower positions are reversed.

And, when the two contact parts 230 are inserted up to the end of the first terminal insertion groove 121, the restraining protrusion 130 formed on the connector housing 100 is connected to the bottom member 231 of the contact part 230. It is restrained by the restraining hole 231a formed in . Accordingly, the terminal 200 is maintained installed in the connector housing 100.

At this time, the two contact parts 230 of the terminal 200 are positioned to face each other from above and below, and the contact spring 232 forming the contact part 230 is exposed into the terminal insertion groove 121 of the connector housing 100. is maintained in its current state.

Accordingly, the connector for direct PCB connection is completed through the above-described work.

Next, the process of connecting the contact point 11 of the PCB 10 and the terminal 200 to each other by coupling the PCB direct connection connector on which the terminal 200 according to an embodiment of the present invention is installed to the PCB 10. Explain.

First, in order to connect the PCB 10 to the PCB direct connection connector, the PCB 10 can be inserted into the insertion groove 110 formed on the front of the connector housing 100.

When the PCB 10 is inserted into the connector housing 100 in this way, the contact points 11 formed on the upper and lower surfaces of the PCB 10, respectively, are connected to the contact spring 232 of the two contact parts 230 forming the terminal 200. is contacted, and thus connection to each other is established.

The PCB direct connection connector of the present invention as described above can be stored or stored because both sides of the contact spring 232 forming the contact portion 230 can be prevented from being exposed to the outside by each side wall cover 233 and 234. Damage to the contact spring 232 can be prevented during assembly.

In particular, as the base 210 is formed to be positioned at a stepped angle from the surface of the two side wall covers 233 and 234, the bending mold can be accurately positioned between the two side wall covers 233 and 234, and thus the two side wall covers 233 and 234 are spaced at precise intervals. It can be formed accurately.

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.
