Description

[Detailed description of the invention] This invention relates to the structure of the contact part of the grounding wire terminal applied to the socket holder of a vehicle lamp, especially the back cover of a lamp in which a plurality of holders are arranged. The purpose of this is to prevent damage to the tip of the grounding wire, as well as the resulting disconnection and poor light distribution.

Conventionally, a simple method for fitting a socket into a socket holder and connecting a grounding wire to it involves peeling off the insulation coating from the tip of the grounding wire and applying a core wire made of stranded wire to the top surface of the socket fitting hole of the holder. Electrical connection is made by press-fitting the socket so that it is sandwiched between the inner periphery of the fitting hole and the outer periphery of the socket.

However, although this method is simple, there is a risk that the core wire may become fatigued and cut due to friction during clamping, and the fitted socket will be tilted by the thickness of the core wire, causing the central axis of the bulb to be tilted by that amount. However, there are disadvantages such as a tendency to cause uneven light distribution.

The present invention is intended to solve the above-mentioned drawbacks, and the specific structure of one embodiment thereof will be described in detail below with reference to the drawings.

FIG. 1A is an enlarged perspective view of the connecting terminal T according to the present invention, showing an embodiment of the present invention. A locking portion t consisting of, for example, a triangular pyramid-shaped protrusion that bites into the circumferential side of the hole is formed.

Fig. 2 is a perspective view showing a state in which a socket (S) is fitted into a socket holder H made of resin.The upper surface of the fitting hole of the holder H has a notch K into which the connection part a of the connection terminal T is inserted, and a socket ' are respectively formed in the notches for taking out the conductive wire l' from S to the other electrode, and inside the notch K, as shown in FIG. 3 as an enlarged sectional view of the fitted state, In addition, the groove W, which is approximately smaller than the thickness of the contact portion, is an important feature.

Since this project has the above-mentioned configuration, we will next discuss the assembly procedure and the effect. In this state, the socket S to which the conducting wire l' is connected is fitted into the fitting hole and press-fitted as it is. This state is shown in FIG. 3 above.

However, since the connecting terminal T is pressed against the outer periphery of the socket S by press-fitting, its locking portion t bites into the groove W formed on the inner periphery of the fitting hole of the resin holder H and is firmly held. It is fixed and maintains a reliable electrical contact with the outer periphery of the socket S. In this way, good conduction with the socket S is obtained, and the tip of the grounding wire L is not damaged or disconnected.
Since the contact part has a flat plate shape made of a thin plate,
Not only can a good light distribution characteristic be obtained without tilting the socket S, but also the notch K allows proper positioning of the connecting terminal T, and the groove W allows the contact part of the connecting terminal to be easily positioned when the socket S is press-fitted. It is easy to work with because it does not wear, and since the locking part t is hammered out in the shape of a triangular pyramid, it is mechanically stronger than simply hammering out a plate-shaped tongue piece, and it firmly bites into the inner periphery of the holder H. It produces various effects that are distantly related to the intended purpose stated at the beginning of the item, such as blocking the movement of the air into the ground and upward.

In addition, FIG. 1 is an actual perspective view showing the connection terminal T' of the modified embodiment, with both sides of the contact portion slightly bent (although the drawing is exaggerated), and the downward slope d and forming an edge e,
The lower part is bent to form a locking part t' with sawtooth-like unevenness formed at the tip.By forming it in this way, the inclination d of the edge e makes the press-fitting operation of the socket)-8 smooth. The edge e opens outward on both sides when pressed to maintain elastic contact with the socket S, and the locking portion t' acts to maintain the locking state similar to that of the first embodiment. do.

Note that even if the locking portion t' is omitted and a raised locking portion t is formed as in the first embodiment, the locking effect remains the same, and the depth of the groove W is It may be set appropriately depending on the wall thickness required for the edge e of the part.
