Detailed Description

As shown in fig. 1, a connection terminal of a lamp comprises a housing 10, a spring plate 20, a pressing block 30 and a pressing piece 40, wherein the spring plate is positioned in the housing, the head end of the spring plate is provided with a strip-shaped groove 21, the spring plate is bent, the tail end of the spring plate is matched in the strip-shaped groove, and the tail end of the spring plate is connected with the inner side wall of the housing; the shell is provided with a first jack 11 and a second jack 12, the first jack and the second jack are staggered and arranged oppositely, and the first jack and the second jack point to the strip-shaped groove; the shell is provided with a guide hole, the pressing block is matched in the guide hole, the pressing piece is arranged outside the shell and has elasticity, one end of the pressing block is abutted or close to the elastic sheet, and the other end of the pressing block is abutted or close to the pressing piece.

In practice, referring to fig. 2 and 3, the lead 51 of the lamp ballast and the lead 52 of the lamp holder may be connected through the connection terminal. The operator presses the casting die 40, and drive briquetting 30 is down, and the bottom of briquetting acts on shell fragment 20, and the shell fragment is further crooked, and the head end of shell fragment is down, and bar groove 21 is down promptly. The operator inserts the lead wire of the ballast into the first insertion hole 11 and the lead wire of the lamp holder into the second insertion hole 12, both of which pass through the bar-shaped groove 21. Then, the operator releases the pressing piece 40, the pressing block rises to reset, the elastic piece also resets under the elastic potential energy, the head end of the elastic piece goes upward, the strip-shaped groove is matched with the tail end of the elastic piece, two leads in the strip-shaped groove are pressed in the strip-shaped groove, and the connection of the leads of the ballast and the leads of the lamp holder is realized.

As shown in fig. 1, the length of the pressing piece 30 is greater than the distance between the pressing piece 40 and the surface of the housing 10, so that the pressing piece is normally restricted in the guide hole by the pressing piece and does not come off the connection terminal. The bottom of briquetting can offset with the shell fragment, also can be close with the shell fragment, and the top of briquetting can offset with the casting die, also can be close with the casting die, promptly, the briquetting as long as keep in the guiding hole can. When the pressing member 40 is pressed down, the pressing member acts on the top end of the pressing block, and the pressing block acts on the elastic piece through the bottom end.

The pressing member 40 is warped, and one end of the pressing member is mounted on the housing 10 by a screw 41. During installation, the pressing block 30 is firstly matched in the guide hole, then the pressing piece is installed by using the screw, and the pressing piece limits the pressing block in the guide hole. The pressing member may be a metal sheet or a plastic sheet, but the pressing member is certainly an insulating member.

The transition position of the middle section and the head end of the elastic sheet 20 is a first bending position 22, and the bottom end of the pressing block 30 is abutted against or close to the elastic sheet, specifically, the bottom end of the pressing block 30 is abutted against or close to the first bending position. Under the action of the pressing piece 40, the bottom end of the pressing piece 30 acts on the first bending part 22, so that the elastic piece 20 is further bent, and the head end of the elastic piece descends. The briquetting contacts with first bend, makes the shell fragment warp more easily, makes the head end of shell fragment down more easily.

A positioning column 13 is arranged in the shell 10, a transition part between the tail end of the elastic sheet and the middle section is a second bending part 23, and the second bending part is pressed against the positioning column; the middle section is provided with a convex part 24 which is positioned at the right side of the positioning column, and the first bending part 22 is positioned at the left side of the positioning column; the convex portion is located above the first insertion hole 11. The pressing block 30 moves downwards to press the first bending part 22, and the first bending part and the convex part 24 are respectively positioned at two sides of the positioning column 13, so that the first bending part is pressed downwards, and the convex part 24 is warped upwards. After the wire is inserted into the first jack 11, the pressing block resets, the first bending part resets upwards, the convex part resets downwards, and the wire is pressed on the wire, so that the wire can be prevented from being separated from the first jack 11.

As shown in fig. 1, the tail end 25 of the spring plate is Z-shaped, and is clamped in the clamping groove 14 of the housing 10, and the clamping groove is arranged on the inner side wall of the housing; the tail end of the elastic sheet is positioned above the first jack 11. The tail end of the Z-shaped elastic sheet enables the first jack to be in a closed-up shape, and the lead is favorably and tightly inserted into the first jack.

Casing 10 form by two sub-casing amalgamations around, install shell fragment 20 in a sub-casing after, another sub-casing closes on the sub-casing that is equipped with the shell fragment through the screw lid.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
