Description

Technical Field [0001] The present invention relates to a shield connector for a board connector,

The present invention relates to a shield connector for protecting a connector for electrically connecting two substrates to each other from an external electromagnetic wave. More particularly, the present invention relates to a shield connector comprising a pair of sockets and a plug, The boards can be easily connected to each other to absorb the coupling shocks of the socket and the plug connected thereto and the coupling errors of the socket and the plugs of the two boards provided in the two boards, And more particularly to a shield connector for connecting a board to a socket housing of a connector so that the shield plate can be easily and stably coupled to shield a connector from external electromagnetic waves or the like .

In general, a product in which a circuit board is used constitutes a main board and an auxiliary board can be connected to the main board so as to add various functions. In order to extend the function of the main board, When connecting auxiliary substrates, a method using a connector or a method using a flexible wire is used.

In the above method, a main board and an auxiliary board are fixed to a frame of the product, and the main board and the auxiliary board are connected by coupling the fixed main board and the auxiliary board with the flexible wire having the connector, In this method, there is a problem in that a space for fixing the main substrate and the auxiliary substrates respectively is secured, resulting in an unnecessarily large size of the product.

Therefore, in recent years, a configuration in which a circuit is connected using a flexible wire as described above is limited to a method that is used only when it is necessary to connect a circuit to a component that performs a rotating operation or a sliding operation in the main body of the product.

Meanwhile, a method of connecting the main board and the auxiliary board to the connector has been applied to various fields for a long time, and an easy example is a configuration in which a memory card, a graphic card, and a sound card are mounted on a motherboard of a computer main body Recently, it is widely used to electrically and circuitly connect the auxiliary substrate of the auxiliary component to the main substrate of the main component by only inserting a product such as car audio used in the automobile into a predetermined position.

That is, in the method of connecting the main board and the auxiliary board to the connector, the main board and the auxiliary board each include a female socket connector and a plug as a male connector, so that the main board and the auxiliary board are connected by the connection of the socket and the plug.

However, as shown in FIG. 1, the main board and the auxiliary board are connected to each other through the connector as described above. When the plug 1 is soldered to another board and the fixed plug 4 is coupled to the socket 1, The terminals 2 and 3 of the socket 1 and the terminals 5 of the plug 4 are inserted into the socket 1 while the terminals 5 and 6 of the plug 4 are inserted outside the terminals 2 and 3 of the socket 1. [ ) 6 are electrically connected to each other.

And a plurality of clips 340 formed at a lower end of the shield plate 300 are inserted into the insertion grooves 112 between the horizontal blockers 125 And is coupled to the upper end of the elastic portion 230 of the terminal 200 connecting the upper housing 110 and the lower housing 140. [

In the present invention constructed as described above, when the socket 100 and the plugs 400 and 500 are soldered to the respective substrates 600, 700 and 700 ', the substrates 600, 700 and 700' The socket 100 and the plugs 400 and 500 can be connected to each other in a state where the socket 100 and the plugs 400 and 500 are connected to each other, The connection failure can be prevented by absorbing shock and vibration transmitted from one side to the upper housing 110 and the lower housing 140, respectively.

That is, the socket 100 of the connector for connecting a board according to the present invention is configured such that the housing is divided into an upper housing 110 and a lower housing 140. In the separated upper housing 110, The connecting portion 210 of the terminal 200 and the lead portion 220 are integrally connected to each other by press-fitting the lead portion 220 of the terminal 200 into the lower housing 140, 230 to maintain the upper housing 110 and the lower housing 140 connected to each other.

The socket 100 and the plug 100 are formed between the upper housing 110 and the lower housing 140 of the socket 100 so that shock and vibration are absorbed by the elastic portion 230 of the terminal 200. Therefore, 400 and 500 are coupled with each other, even if shock or vibration is transmitted from either the upper housing 110 or the lower housing 140 during use, the elastic portion 230 of the terminal 200, So that the socket 100 and the plugs 400 and 500 can securely contact the terminals 200, 420 and 520, Defects and the like can be prevented in advance.

Particularly, the socket 100 of the present invention is provided with a shield plate 300 on the front and rear surfaces of the upper housing 110. The shield plate 300 has both ends 320 on both sides of the upper housing 110, The fixed joint part 120 and the elastic coupling part 330 are inserted into the guide groove 111 formed on both sides and the lower end part 321 of the shield plate 300 is inserted into the seating part 126 of the combined horizontal blocker 125. [ So that the upper housing 110 and the shield plate 300 can be stably engaged.

That is, when both side ends 320 of the shield plate 300 are guided and inserted into the guide groove 111 of the upper housing 110, the elastic hook 331 of the elastic coupling part 330 is inserted into the guide groove 111 of the upper housing 110, The elastic hooks 331 are separated from the elastic hooks 331 while the elastic hooks 331 are in contact with each other while passing through the fixed hooks 121, The upper housing 110 and the shield plate 300 are maintained in a stable state of engagement.

Since the fixed hook 120 is integrally formed between the upper housing 110 and the vertical blocker 124, the resilient hook 331 coupled to the fixed hook 120 is engaged with the coupling between the steps 123 and 333, And the elastic hooks 331 are coupled to each other in a state in which two of the fixed hooks 120 and the elastic hooks 331 are opposed to each other so that the elastic hooks 331 are prevented from being separated in the opposite direction of coupling, The upper housing 110 and the shield plate 300 can be maintained in a more stable state because the vertical blocker 124 prevents the upper housing 110 and the shield plate 300 from being separated.

The upper housing 110 and the shield plate 300 may be coupled by the guide groove 111 as in the first embodiment, The guide groove 111 of the first embodiment and the fixed engaging portion 120 and the elastic engaging portion 330 of the second embodiment as in the third embodiment, The upper housing 110 and the shield plate 300 may be coupled to each other to maintain a more stable coupled state.

The plurality of clips 340 formed at the lower end of the shield plate 300 are inserted into the elastic portion 230 of the terminal 200 when the upper housing 110 and the shield plate 300 are coupled as described above, Since the clip 340 can be grounded through the terminal 200, the socket 100 of the present invention can be easily connected to the front surface and the rear surface of the terminal 200, Shielding effect can be obtained by the shield plate 300. [

That is, since the clip 340 according to the present invention is configured such that the lower side of the clip 340 is elastically opened at the lower end of the shield plate 300, the shield plate 300 is inserted along the guide groove 111 into the seating groove 126 of the horizontal blocker 125, The clip 340 is naturally coupled to the terminal 200 when it is inserted into the upper housing 110.

The clip 340 can stabilize the coupling state between the clip 340 and the terminal 200 by the elastic force of the clip 340. When the lead portion 220 of the terminal 200 is soldered to the board 600, Since the socket 300 is naturally grounded, it is possible to shield the socket 100 from the interference of the electromagnetic wave even without forming a separate grounding terminal, The shield plate 300 is provided with the terminals 200 to be coupled to the clip 340 at regular intervals in the middle of the terminals 200 according to the number of the terminals 200 provided therein, Of course, the terminal 200 coupled to the clip 340 serves as a shield, so that the terminals 200 used for the electrical connection can be shielded from the interference of the electromagnetic wave at the closest position.

Particularly, even when the clip 340 of the shield plate 300 and the elastic portion 230 of the terminal 200 are engaged by the present invention, the elastic portion 230 of the terminal 200 can be moved in the X- The buffering action of the vibration and the buffering action of the front and rear side vibrations in the Y axis direction can be performed perfectly.

That is, the buffering action of the upper and lower vibration in the Z axis direction is performed between the terminal 200 of the socket 100 and the terminals 420 and 520 of the plugs 400 and 500. However, The movement of the upper housing 110 is directly transmitted to the shield plate 300 fixed to the front and back surfaces of the upper housing 110. The movement of the clip 340 of the shield plate 300, And is transferred to the terminal 200 coupled to the clip 340 as it is and moves in the vibration direction.

The terminals 200 that are not coupled to the clip 340 and used for electrical connection are inserted into the gap holding portion 130 formed at the upper housing 110 of the elastic portion 230, The elastic portions 230 of the terminals 200 move together with the upper housing 110 to absorb shocks and vibrations in the left and right directions.

That is, the interval maintaining part 130 repeatedly forms the segment 131 and the cutout recess 133 by the number of the terminals 200, and the upper end of the elastic part 230 of the terminal 200 is formed as a slope The left and right movements of the upper housing 110 lead to an operation of pushing the upper ends of the elastic portions 230 through the ribs 131 integrated with the upper housing 110 The terminals 200 coupled to the clip 340 as well as the terminals 200 used for the electrical connection can be operated together to perform the buffering action in the left and right directions.

Meanwhile, the shock transmitted to the front and rear sides of the upper housing 110 allows the clip 340 to slip and move at the upper end of the elastic portion 340, thereby restricting the movement of the elastic portion 230, It is.

That is, when the upper housing 110 moves forward and backward due to the impact transmitted in the front and rear directions, the shield plate 300 and the clip 340 fixed to the upper housing 110 move together with the upper housing 110 .

Since the lid part 220 of the terminal 200 connecting the upper housing 110 and the lower housing 140 is coupled to the lower housing 140 fixed to the board 600, Since the elastic part 230 as well as the elastic part 230 are fixed in position, the elastic part 230 is elastically compressed while being folded like a winding, and the clip 340 coupled to the elastic part 230 is elastic So that the shock can be absorbed.

In this case, when the clip 340 is not separated from the elastic part 230 of the terminal 200 within a limit distance range in which the movement of the upper housing 110 can be buffered, a stable buffering effect in the front and rear direction can be obtained When the combined shock in the front and rear left and right directions is transmitted, the buffering operation in the left and right direction and the buffering operation in the forward and backward directions are performed at the same time, so that efficient shock absorption can be achieved.

In particular, the buffering action of the left and right motions in the X-axis direction and the buffering action of the front and rear motions in the Y-axis direction can efficiently absorb the coupling shock between the socket 100 and the plugs 400 and 500, The operation of absorbing the coupling errors in the different directions of the socket 100 and the plugs 400 and 500 fixed within the tolerances of the substrates 600, 700 and 700 ' .
