Description
본 고안은 표면실장형 암커넥터의 보강핀 체결구조에 관한 것으로, 더욱 상세하게는 인쇄회로기판에 직접실장되는 표면실장형 암커넥터의 리드핀이 휘는 것을 방지하기 위해 구비하는 보강핀의 체결구조에 관한 것이다.The present invention relates to a reinforcing pin fastening structure of a surface mount female connector, and more particularly, to a reinforcing pin fastening structure provided to prevent bending of a lead pin of a surface mount female connector directly mounted on a printed circuit board. It is about.
일반적으로 인쇄회로기판의 표면에 실장되는 암커넥터는 그 크기가 매우 작고 낮은 높이를 갖도록 만들어져 있기 때문에 이 암커넥터로부터 인출된 리드핀의 크기를 작게 만들 수 밖에 없으므로, 리드핀의 강도가 취약하여 보강수단을 마련하지 않은 상태에서 수커넥터를 삽입하게 되면, 암커넥터가 인쇄회로기판으로부터 들뜨는 현상이 발생되면서 리드핀이 휘게 된다.In general, since the female connector mounted on the surface of the printed circuit board has a very small size and a low height, the size of the lead pin drawn out from the female connector is inevitably reduced. When the male connector is inserted without a means, the lead pin is bent while the female connector is lifted from the printed circuit board.
따라서 인쇄회로기판의 표면에 실장되는 암커넥터에는 리드핀과 별도로 인쇄회로기판에 솔더링되는 보강핀을 두도록 되어 있는데, 이러한 보강핀을 갖는 종래의 암커넥터의 예를 첨부도면 도1 내지 도4에 도시하고 있다.Therefore, the female connector mounted on the surface of the printed circuit board is to have a reinforcement pin soldered to the printed circuit board separately from the lead pin, an example of a conventional female connector having such a reinforcement pin is shown in the accompanying drawings. Doing.
먼저, 첫 번째 예는 첨부도면 도1 및 도2에 도시된 바와 같이 암커넥터(10)의 후부로부터는 인쇄회로기판(11)에 솔더링되는 리드핀(12)이 인출되어 있으며, 이 암커넥터(10)의 좌우양측에는 상하방향으로 연장된 도브테일홈(13a)(14a)을 갖는 리브(13)(14)가 형성되어 있고, 이에 "L"자 모양으로 굽은 보강핀(15)(16)이 아래쪽으로부터 위쪽을 향하여 삽입되도록 구성되어 있었다.First, in the first example, as shown in FIGS. 1 and 2, a lead pin 12 soldered to the printed circuit board 11 is drawn from the rear of the female connector 10, and the female connector ( 10 and 14, ribs 13 and 14 having dovetail grooves 13a and 14a extending in the vertical direction are formed, and reinforcing pins 15 and 16 which are bent in an “L” shape are formed. It was configured to be inserted from the bottom upwards.
그러나, 이와 같은 종래의 보강핀(15)(16)을 체결하기 위한 리브(13)(14)에 형성된 도브테일홈(13a)(14a)이 암커넥터(10)를 성형하기 위한 금형의 빼기방향에 대해 직각인 상하방향으로 형성되어 있으므로, 2분할이 아닌 그 이상의 분할수를 갖는 금형을 필요로하게 되어 금형제작비용이 보다 많이 들게 된다는 문제점을 가지고 있었으며, 수커넥터(17)를 삽입할 때 상기 암커넥터(10)에 작용되는 들뜨는 방향과 거의 동일한 방향인 상하방향으로 보강핀(15)(16)이 삽입되도록 구성되어 있기 때문에 암커넥터(10)에 과도한 힘을 가하게 되면, 암커넥터(10)가 보강핀(15)(16)으로부터 빠져나오게 되는 문제점을 가지고 있었다.However, the dovetail grooves 13a and 14a formed in the ribs 13 and 14 for fastening the conventional reinforcement pins 15 and 16 are in the withdrawal direction of the mold for forming the female connector 10. Since it is formed in the vertical direction perpendicular to the, it has a problem that a mold having a divided number of more than two divisions is required, so that a mold manufacturing cost is higher, and when the male connector 17 is inserted, the female When the reinforcing pins 15 and 16 are inserted in the up and down direction, which is almost the same as the lifting direction acting on the connector 10, when the female connector 10 is subjected to excessive force, the female connector 10 It had a problem to come out of the reinforcement pins (15) and (16).
또한, 두 번째 예는 첨부도면 도3 및 도4에 도시된 바와 같이 암커넥터(20)의 후부로부터는 인쇄회로기판(21)에 솔더링되는 리드핀(22)이 인출되어 있으며, 이 암커넥터(20)의 좌우양측에는 후방측에서 전방측을 향해 삽입하는 "L"자 모양의 단면형태를 갖는 걸림홈(23a)(24a)이 형성된 리브(23)(24)가 각각 좌우양측으로부터 돌출형성되어 있었고, 이 양측의 걸림홈(23a)(24a)에 삽입되어 걸리는 옆으로 눕힌 "U"자 모양의 단면모양을 갖는 보강편(25)(26)이 후방측으로부터 전방측을 향해 삽입되도록 구성되어 있었다.In the second example, as shown in FIGS. 3 and 4, a lead pin 22 soldered to the printed circuit board 21 is drawn from the rear of the female connector 20, and the female connector ( On the left and right sides of the rib 20, ribs 23 and 24 having locking grooves 23a and 24a having an L-shaped cross section inserted from the rear side to the front side are protruded from the left and right sides, respectively. The reinforcing pieces 25 and 26 having a side-by-side " U " -shaped cross section inserted into the engaging grooves 23a and 24a on both sides thereof are configured to be inserted from the rear side to the front side. there was.
그러나, 이와 같은 것은 매우 작은 폭을 갖는 걸림홈(23a)(24a)을 성형하기 위한 금형에 이와 같은 걸림홈(23a)(24a)의 폭과 같은 얇은 부분을 만들어야 하나 강도가 취약하여 금형의 수명이 단축된다는 문제점을 가지고 있었으며, 우선 보강편(25)(26)을 옆으로 눕힌 형태의 "U"자 모양으로 굽힌 다음 삽입하여야 하기 때문에 삽입과 동시에 굽힘가공을 하는 한번의 공정으로 여러공정을 동시에 마치는 복합조립공정에 부적합하게 되어 생산성을 저하시킨다는 문제점을 가지고 있었다.However, such a thing should be made in the mold for forming the locking grooves 23a and 24a having a very small width, such as the width of the locking grooves 23a and 24a, but the strength is weak so that the life of the mold is weak. The shortening of the reinforcing pieces (25) and (26) in the form of a "U" in the form of the side laid down and then inserted into the bending process at the same time inserting and bending at the same time several processes at the same time Machi has a problem in that it is unsuitable for the composite assembly process to reduce the productivity.
본 고안은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 금형의 분할수를 증대시키지 않는 구조를 갖으며, 과도한 힘이 가하여 지더라도 암커넥터가 보강핀으로부터 분리되지 않고, 복합조립공정에 적용할 수 있는 암커넥터를 제공함에 있다.The present invention is made to solve the above problems, the purpose is to have a structure that does not increase the number of division of the mold, even if excessive force is applied to the female connector is not separated from the reinforcing pin, composite assembly process It is to provide a female connector applicable.
이러한 본 고안의 목적을 달성하기 위하여 인쇄회로기판의 표면에 솔더링되는 리드핀이 후방측에 형성되어 있고, 보강핀을 갖는 표면실장형 커넥터의 보강핀 체결구조에 있어서, 암커넥터의 앞면 좌우양측에 핀삽입구멍을 형성하고, 이 핀삽입구멍과 연이어지는 홈이 상측으로부터 저면까지 연장되어 형성되어 있는 걸림돌기를 형성하는 한편, 상기 핀삽입구멍에 삽입되도록 전방측에서 후방측을 향해 절곡되는 상단절곡부와, 상기 암커넥터의 저면에 형성되어 있는 홈으로 삽입되도록 절곡되는 하단절곡부를 상기 보강핀에 형성하여 구성된 특징을 갖는다.In order to achieve the object of the present invention, a lead pin soldered to the surface of the printed circuit board is formed on the rear side, and in the reinforcement pin fastening structure of the surface mount connector having reinforcement pins, the front and rear sides of the female connector An upper bent portion which forms a pin insertion hole, a groove formed in which a groove connected to the pin insertion hole extends from an upper side to a bottom surface, and which is bent from the front side to the rear side to be inserted into the pin insertion hole; And a lower bent portion bent to be inserted into a groove formed in the bottom surface of the female connector on the reinforcement pin.

One example is shown.
이하 본 고안에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.
먼저, 첨부도면 도5 및 도6에 도시된 바와 같이 보강핀(70)(72)에 형성되어 있는 상단절곡부(70a)(72a)를 선두로하여 암커넥터(60)의 앞면 좌우양측에 형성되어 있는 핀삽입구멍(62a)(64a)으로 삽입하게 되면, 보강핀(70)(72)이 홈(66)(68)에 삽입됨과 동시에 걸림돌기(62)(64)에 걸리는 꼴이 된다.First, as shown in FIGS. 5 and 6, the upper bent portions 70a and 72a formed on the reinforcement pins 70 and 72 are formed on the front left and right sides of the female connector 60 as a head. When inserted into the pin insertion holes 62a and 64a, the reinforcing pins 70 and 72 are inserted into the grooves 66 and 68, and at the same time, they are caught by the locking projections 62 and 64.
위와 같은 상태에서 암커넥터(60)로부터 인출되어 있는 리드핀(50)(52)과 보강핀(70)(72)을 인쇄회로기판(40)의 패턴에 솔더링한 다음 수커넥터(도시 않됨)를 삽입하게 되면, 암커넥터(60)가 리드핀(50)(52)을 기점으로 인쇄회로기판(40)에서 회전하려는 휨모멘트가 작용되는데, 이때 암커넥터(60)의 앞쪽에 위치되어 있는 보강핀(70)(72)이 인쇄회로기판(40)에 솔더링되어 있으므로, 들뜨는 것이 방지된다.In the above state, the lead pins 50, 52 and reinforcement pins 70, 72 drawn out from the female connector 60 are soldered to the pattern of the printed circuit board 40, and then a male connector (not shown) is connected. When inserted, the bending moment to which the female connector 60 is to rotate on the printed circuit board 40 is applied to the lead pins 50 and 52, wherein the reinforcement pins are located in front of the female connector 60. Since 70 and 72 are soldered to the printed circuit board 40, lifting is prevented.
더욱이 보강핀(70)(72)이 걸림돌기(62)(64)에 걸린 상태로 있으므로, 보강핀(70)(72)과 암커넥터(60)가 서로 분리되는 것이 방지된다.Furthermore, since the reinforcing pins 70 and 72 are caught in the locking projections 62 and 64, the reinforcement pins 70 and 72 and the female connector 60 are prevented from being separated from each other.
이상에서 설명한 바와 같은 본 고안은 보강핀을 고정하기 위해 암커넥터에 형성되어 있는 핀삽입구멍과 걸림돌기, 홈 등이 몸체를 성형하기 위한 금형의 빼기방향에 대해 모두 평행하게 되어 있으므로, 금형의 분할수를 증대시킬 필요가 없게 되어 금형비를 절감할 수 있게 되는 효과가 있으며, 암커넥터에 작용되는 휨모멘트에 대항하는 걸림돌기가 구비되어 있으므로, 보강핀에 과도한 힘이 가해지더라도 아커넥터로부터 이탈되는 것을 방지할 수 있는 효과가 있고, 보강핀을 암커넥터에 삽입하면서 굽힘가공도 할 수 있으므로, 한번의 공정으로 여러공정을 마칠 수 있는 복합조립공정에 적용할 수 있으므로, 생산성을 보다 향상시킬 수 있는 효과가 있다.In the present invention as described above, since the pin insertion hole, the locking projection, and the groove formed in the female connector are parallel to the ejection direction of the mold for forming the body, the mold is divided in order to fix the reinforcement pin. There is no need to increase the number, which reduces the mold cost, and is provided with a locking projection against the bending moment acting on the female connector, thereby preventing the connector from being separated from the connector even if excessive force is applied. It can be used and can be bent while inserting the reinforcing pin into the female connector. Therefore, it can be applied to a complex assembly process that can be completed in one step. Therefore, the productivity can be further improved. have.
