Description

FIELD OF THE INVENTION [0001] The present invention relates to a socket terminal for an electrical connector, a socket terminal for an electrical connector, and a socket assembly for an electrical connector and an electrical connector,

[0001] The present invention relates to an electrical connector, and more particularly to an electrical connector, in which a pin contact portion includes a first face and a pair of first arms formed on a face facing the first face, a second face formed on the face facing the second face, A pair of second arms are formed, and the pins are in contact with the first arm and the second arm.

Electronic equipment requires an electrical connector that provides connection to the signal path.

The pin and socket type connectors are used to provide a detachable and electrically reliable interface.

The conventional method normally positions one receptacle cantilever beam on the projecting pin or on opposite sides of the blade, as shown in Figure 1 (a). That is, the pins and the terminals are in contact with each other on two surfaces.

However, in this case, there is a problem that one or both portions of both sides of the pin are in contact with each other and are not stably contacted.

In addition, there is a problem that the initial yielding rate of the contact point is high, so that the pin is substantially embedded in the terminal of the socket.

In addition, conventional terminals of the connector use a general beryllium copper such as beryllium copper 7 (tensile strength: 68.3 to 81.6 kgf / mm 2, yield strength: 56 to 77.5 kgf / mm 2) of 0.15 t, .

Further, there is a problem that the contacted portion deviates from the center line.

In addition, there is a problem in that flux and solder are introduced into the terminal when soldering the terminal because the terminal is opened between the terminal and the terminal.

Another conventional method places two receptacle cantilever beams at the top and bottom on the facing surface, as shown in Figure 1 (b). That is, the pins and the terminals come in contact with each other in two parts on the two sides and come in contact with the two sides and four sides. Also in this case, there is a problem that the initial yielding rate of the contact point is high so that the pin is substantially embedded in the terminal of the socket, there is a problem that the contact portion deviates from the center line, and there is a problem of widening the interval between the contact points to lower the insertion force, There is a problem that the flux and the solder are introduced into the terminal when soldering the terminal because the portion between the terminal and the terminal is opened between the terminal and the terminal.

Such conventional terminals result in very high stresses of 250 to 350 kgf / mm < 2 > when the receptacle cantilever beam contacts the pin. In addition, when the receptacle cantilever beam contacts the pin, a very high contact pressure of 370 gf is generated, and permanent deformation occurs in the receptacle cantilever beam, and the repeated durability is remarkably deteriorated.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

For reference, the same components as those of the conventional art will be described with reference to the above-described prior art, and a detailed description thereof will be omitted.

2 to 14, an electrical connector according to an embodiment of the present invention includes a socket 400, a terminal 500 inserted into the socket 400, A pin inserted into the terminal 500 and a header 200 having a plurality of pin through holes 210 into which the pin 100 is inserted, And a terminal 520 formed below the pin contact portion 510. The pin contact portion 510 includes a first surface 511 and a surface 513 facing the first surface 511 And a pair of second arms 502 formed on a second surface 512 and a surface 514 facing the second surface 512, And the pin (100) is in contact with the first arm (501) and the second arm (502).

As shown in FIG. 2, the pin 100 is provided with a square pin whose horizontal cross-sectional shape is formed in a square (e.g., square) shape. The pin (100) is formed with a tapered portion at its upper and lower ends. The tapered portion is formed to have a smaller cross sectional area toward the end.

The pin 100 is inserted into the terminal 500.

As shown in FIGS. 2 and 3, the terminal 500 includes a pin contact portion 510 and a terminal 520 formed under the pin contact portion 510 and soldered to the substrate.

Terminal 500 may be formed of beryllium copper with improved electrical conductivity, such as beryllium copper 11 alloy. Beryllium Copper 11 alloy has a tensile strength of 77.5 ~ 98.4 kgf / ㎟ and a yield strength of min. 66.8 kgf / mm < 2 >.

The terminal 500 is manufactured through bending as described below so that the pin contact portion 510 and the terminal 520 are integrally formed.

3 to 6, the pin contact portion 510 includes a first surface 511, a surface facing the first surface 511 (hereinafter, referred to as a 'third surface') 513, A second surface 512 adjacent to the first surface 511 and a surface 514 facing the second surface 512 (hereinafter referred to as a fourth surface 514).

The first side 511 is the right side, the second side 512 is the front side, the third side 513 is the left side, and the fourth side 514 is the rear side.

The upper surface of the second surface 512 and the upper surface of the fourth surface 514 are connected to each other by a connecting surface 515, Lt; / RTI > Therefore, the pin contact portion 510 is formed in a rectangular parallelepiped shape.

Both sides 518 of the second surface 512 are roundly bent toward the first surface 511 and the third surface 513. Therefore, when the terminal 500 is inserted into the socket 400, it can be smoothly inserted.

The pin contact portion 510 is formed with an arm which contacts the pin 100. The arm has a first surface 511 and a pair of first arms 501 formed on a surface 513 facing the first surface 511 and a second surface 512 formed on the second surface 512, And a pair of second arms 502 formed on opposite sides of the first arm 502.

Thus, the arm is formed on each surface, and the durability of the terminal 500 is further improved.

That is, the first arm 501 is formed on the first and third surfaces 511 and 513, and the second arm 502 is formed on the second and fourth surfaces 512 and 514.

The pair of first arms 501 are formed to correspond to each other, and are arranged to face each other.

The pair of second arms 502 are formed to correspond to each other and are arranged to face each other.

The first arm 501 is in contact with the right side and the left side of the pin 100 respectively and the second arm 502 is in contact with the front side and the rear side of the pin 100, respectively. As such, the first arm 501 and the second arm 502 are in contact with different surfaces of the pin 100.

In this way, the terminal 500 and the pin 100 are brought into contact with each other at four sides, the initial yielding rate of the contact can be minimized, the contact point and the center line can be matched, and the contact state can be stably maintained. Repetitive durability is improved, and contact plating damage is minimized.

The first arm 501 and the second arm 502 are connected to the pin contact portion 510 in a cantilever manner. Therefore, the first arm 501 and the second arm 502 can be elastically deformed smoothly.

The first arm 501 has a lower end connected to the pin contact portion 510 and the second arm 502 has an upper end connected to the pin contact portion 510. Thus, the first arm 501 has the free end 505 disposed thereon, and the second arm 502 has the free end disposed thereunder.

In addition, the first arm 501 and the second arm 502 are formed by cutting a part of the surface of the pin contact portion 510. Therefore, the first arm 501 and the second arm 502 are formed with a cut along one or both sides and the upper or lower end.

A portion cut away from the first arm 501 is formed on both sides 518 of the second surface 512 toward the first surface 511 and the third surface 513. Therefore, the elastic deformation of the first arm 501 can be smooth. The lower portions of the portions bent from the both sides 518 of the second surface 512 toward the first surface 511 and the third surface 513 are brought into contact with the first and third surfaces 511 and 513.

The first arm 501 and the second arm 502 are formed as described above. The pin contact portion 510 has a surface which is supported at each corner portion arranged in the vertical direction, and the shape of the terminal 500 And the first arm 501 and the second arm 502 are stably supported.

The first arm 501 and the second arm 502 are bent toward the inside.

Accordingly, the distance between the pair of second arms 502 becomes smaller as they are directed downward. Further, the distance between the pair of first arms 501 becomes smaller as they are directed upward.

In addition, the free ends 505 of the first arm 501 and the second arm 502 are bent outward. The first arm 501 and the second arm 502 are in contact with the pin 100 at the inner side of the outwardly bent point.

Therefore, the lower ends of the pair of second arms 502 are spaced apart from each other as they approach the free ends. In addition, the upper ends of the pair of first arms 501 are spaced apart from each other toward the free end 505.

Therefore, the portions where the first arm 501 and the second arm 502 come into contact with the pins 100 are disposed apart from each other along the longitudinal direction (vertical direction) of the pins 100. Specifically, the portion where the first arm 501 and the pin 100 are in contact is disposed above the portion where the second arm 502 and the pin 100 are in contact with each other. That is, when the pin 100 is inserted into the terminal 500, the pin 100 is inserted between the pair of first arms 501 and is first contacted with the pair of first arms 501, 2 arm 502 and is in contact with a pair of second arms 502. [

The first and second arms 501 and 502 are formed so that the pin 100 can smoothly flow into the first and second arms 501 and 502 without being caught by the first and second arms 501 and 502, .

Further, the pin contact portion 510 is formed with a separation surface 516 disposed between the terminal 520 and the first and second arms 501, 502.

The separation surface 516 is formed to be connected to the lower end of the second surface 512.

The separation surface 516 is formed by bending a part of the second surface 512. That is, the separation surface 516 is formed integrally with the second surface 512.

The separation surface 516 is formed in a horizontal plate shape and separates the space in which the terminal 520 is disposed and the space in which the first and second arms 501 and 502 and the pin 100 are disposed.

This separation surface 516 prevents the flux or solder from penetrating into the pin contact 510 when soldering the terminal 520 to the substrate.

The pin contact portion 510 may be provided with a connecting surface 515 connecting the upper surface of the third surface 513 with the first surface 511 or connecting the upper surface of the fourth surface 514 with the second surface 512, .

In this embodiment, the connecting surface 515 connects the second surface 512 to the top of the fourth surface 514. [

Such a connection surface 515 prevents the gap between the pair of second arms 502 from spreading. Therefore, the repeat durability of the terminal 500 is further improved.

The connecting surface 515 is integrally formed on the upper surface of the second surface 512 and the upper surface of the fourth surface 514.

The connecting surface 515 is formed in a horizontal plate shape. The connection surface 515 is formed with an insertion hole 517 through which the pin 100 can be inserted in a vertical direction.

A wedge-shaped protrusion 519 is formed on the outer circumferential surface of the lower surface of the second surface 512 and the fourth surface 514 to protrude outward.

The protrusion 519 is formed so as to protrude further outward (in the direction opposite to the direction in which the terminal 500 is inserted into the socket 400) toward the bottom. Therefore, the terminal 500 can be firmly fitted to the socket 400 with a simple structure.

The protrusion 519 may be formed by pressing the second surface 512 and a part of the fourth surface 514 inwardly. Thus, the protrusion 519 can be formed by a simple process.

The terminal 520 is formed to be connected to the lower portion of the fourth surface 514, and is bent backward and then bent downward again.

Such a terminal can be manufactured by the following method.

The method for manufacturing a socket terminal for an electric connector according to the present embodiment includes: an arm forming step of forming four arms on a plate; bending both sides of the plate to press the first face 511 and the face facing the first face 511 And a bending step of bending an upper portion of the plate material to form a second surface 513, the arm having a first surface 511 and a second surface 512 facing the first surface 511 513, the second surface 512, and the surface 514 facing the second surface 512, respectively.

In the arm forming step, the arm is formed by cutting both sides or one side and the lower part or the upper part of the arm. The arms include a pair of first arms 501 formed to correspond to each other and a pair of second arms 502 formed to correspond to each other.

The bending step includes bending the both sides of the plate material forward to form the first and third surfaces 511 and 513, bending the upper portion of the plate material forward to form a connection surface 515, The second surface 512 is formed and the end of the second surface 512 is bent back to the rear surface (toward the fourth surface 514) to form the separation surface 516. [

The bending step is performed such that a pair of first arms 501 are formed on the first and third surfaces 511 and 513 and a pair of second arms 502 are formed on the second and fourth surfaces 512 and 514.

In the bending step, both sides 518 of the second surface 512 are bent toward the first surface 511 and the third surface 513.

An insertion hole 517 through which the pin 100 is inserted is formed in the connection surface 515 connecting the second surface 512 and the upper surface of the fourth surface 514 before the bending step.

The terminal 520 is integrally formed on the lower surface of the fourth surface 514.

2 and 7, the socket 400 is formed in the shape of a rectangular parallelepiped, and a pin insertion hole 410 through which the pin 100 is inserted is formed at an upper portion, and a pin insertion hole 410 A terminal groove 430 into which the pin contact portion 510 of the terminal 500 is inserted is formed.

A plurality of pin insertion holes 410 and terminal grooves 430 are formed in the socket 400.

The pin insertion hole 410 is formed in the up-and-down direction to open the top.

As shown in FIG. 8, a tapered portion is formed on the upper portion of the pin insertion hole 410 so that the horizontal cross-sectional area becomes wider toward the upper portion.

The terminal groove 430 is formed in a vertical direction so as to open the lower portion.

A tapered portion is formed at a lower portion of the terminal groove 430 so that the horizontal cross-sectional area becomes wider as it goes downward.

A rib 431 is formed on the lower surface of the socket 400 around the terminal groove 430.

The ribs 431 are formed in a lattice shape in which a plurality of terminal grooves 430 are separated and a plurality of terminal grooves 430 are opened front and rear so as to communicate with the outside. As a result, when each terminal is soldered, an escape space is provided in the periphery to prevent penetration of flux or solder. Further, the soldering state can be confirmed from the outside. Also, cold soldering and lifting are prevented.

The upper and lower lengths H of the terminal groove 430 are formed to be longer than the upper and lower lengths h of the pin contact portion 510 so that the lowest end of the socket 400 is disposed lower than the lowermost end of the pin contact portion 510. As such, the soldered portion and the pin contact portion 510 are spaced apart to prevent flux or solder from penetrating when soldered.

As shown in FIG. 2, the header 200 is formed in a plate shape, and a plurality of pin through holes 201 into which the pins 100 are inserted are formed.

The pin through hole 210 is formed so as to penetrate in the vertical direction.

On the upper and lower surfaces of the header 200, a recessed groove 202 is formed around the pin through hole 210.

The draining groove 202 is formed in a lattice shape.

The slit grooves 202 are formed so as to surround a part of the circumference of the pin through hole 210, not to surround the on-hole.

Due to the recessed grooves 202, the header 200 is prevented from being bent, and cracks are prevented from being formed when the pins 100 are assembled.

The header 200 has a plurality of grooves 203 formed on its front surface and rear surface. The groove 203 is disposed between the two pin through holes 210.

The pin 100 inserted in the header 200 is inserted into the pin insertion hole 410 of the socket 400 and inserted into the insertion hole 517 of the pin contact portion 510 to be contacted with the arm.

Further, as shown in FIG. 11, a vacuum cap 300 for transferring the socket 400 using vacuum suction may be provided.

The vacuum cap 300 is fitted to the upper portion of the socket 400 when the socket 400 is transferred and removed from the socket 400 after the transfer is completed. With this vacuum cap 300, the socket 400 can be easily transported.

The vacuum cap 300 includes a cap top surface 310 disposed at an upper portion of the socket 400 and a cap side wall 320 protruding downward at an opposite end of the cap top surface 310.

The cap top surface 310 is formed flat.

The cap sidewall 320 is formed in front of and behind the cap top surface 310.

A depression 402 is formed at a middle portion between the front surface and the rear surface of the socket 400 where the cap side wall 320 is disposed. The width of the depressed portion 402 is longer than the width of the cap side wall 320.

One of the cap side wall 320 and the socket 400 has a hook 322 and the other has a hook 421 to which the hook 322 is hooked.

The latching hook 322 is formed on the inner side of the cap side wall 320 and the latching portion 421 is formed on the front side and the rear side of the socket 400 in this embodiment.

A cutout hole 311 is formed in the cap top surface 310 along the cap sidewall 320. The incision hole 311 is elongated along the left and right directions on the front and rear sides of the cap top surface 310.

The incision hole 311 is formed in the vertical direction. The cutout hole 311 is open at the top and the inside.

12, a hooking hook 322 is formed in the cap side wall 320 due to the cutout hole 311. As shown in FIG.

The hooking hook 322 is elongated in the left-right direction.

The latching part 421 is formed to protrude forward or backward on the upper part of the central part of the front surface and the rear surface of the socket 400. Therefore, the engaging portion 421 is disposed inside the depressed portion 402. Therefore, the engaging portion 421 does not protrude outward beyond the outermost end of the socket 400.

As shown in Fig. 14, the upper surface and the lower surface of the engaging portion 421 are formed to be inclined.

When the vacuum cap 300 is placed on the socket 400 and then pushed down toward the socket 400, the latching hook 322 is engaged with the latching portion 421 after being elastically deformed. Through this process, the vacuum cap 300 is inserted into the socket 400. By this simple process, the vacuum cap 300 can be fitted into the socket 400.

As a result, the socket 400 does not move up and down with respect to the vacuum cap 300.

A key 422 is formed in one of the socket 400 and the vacuum cap 300 and a key groove 321 in which the key 422 is inserted is formed in the other.

In this embodiment, the key 422 is formed in the socket 400, and the key groove 321 is formed in the vacuum cap 300.

The key 422 is formed in the vertical direction (the direction in which the vacuum cap 300 is fitted), and is disposed in the middle of the engaging portion 421.

The key groove 321 is formed in the vertical direction at the middle portion of the engaging hook 322.

When the vacuum cap 300 is fitted into the socket 400, the key 422 is inserted into the key groove 321. Therefore, the socket 400 does not flow in the lateral direction with respect to the vacuum cap 300.

On the lower surface of the cap top surface 310, a lower groove 312 is formed along the left and right direction. The lower groove 312 is formed so that the lower portion thereof is opened. The lower grooves 312 are formed on the front side and the rear side, respectively. The lower grooves 312 are disposed between the cut holes 311.

During the SMT operation, the vacuum cap 300 is inserted into the socket 400 as described above. After the SMT operation, the vacuum cap 300 is removed and the subsequent process is performed.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims .
