Description

[Detailed Description of the Invention] The present invention relates to a connector for connection with a headlamp of an automobile.

Conventionally, there are two types of car headlamps: two-lamp type and four-lamp type.
The light type has a headlamp for both high and low use and a headlamp for high only, and the headlamp for both high and low use has an electric connector for high, an electric connector for low, and a common electric connector for high and low. Three connectors are provided, and the high-only headlamp is provided with two high-use electrical connectors.

Therefore, the connector connected to such a headlamp has been formed as a multi-pole connector that accommodates three or two electrical connectors for connection with the above-mentioned electrical connector.
Since the mechanical connection with the headlamp relied solely on the mutual fitting of the electrical connectors without using any locking means, the connection could be inadvertently broken due to vibrations of the automobile.

In view of the above-mentioned drawbacks, the present application provides means for locking the electrical connector to at least one of the electrical connectors in the multi-pole connector for connection with the electrical connector attached to the headlamp. The present invention attempts to solve the above-mentioned drawbacks by fixing the multi-pole connector to the headlamp.

An example of the implementation of the present invention will be described below using a connector for connection with a headlamp for both high and low use.

FIG. 1 is a perspective view showing a state before the connector and headlamp are connected according to the present invention, and in the figure, 1 is the headlamp main body, and 2 is the connector main body.

The headlamp body 1 has a low electrical connector 3, a high electrical connector 4, and a high/low electrical connector 5 protruding from the back, and each electrical connector 3.4.5 has a tab-shaped electrical contact. A perforation lower is provided in the center of the portion 6.

The connector body 2 includes electrical connectors 〇, 9.10 for connection with the electrical connectors 3, 4.5, and the electrical connectors 8, 9.
．． At least one of the electrical connectors 8, 9, and 10, for example, the electrical connector 8, is formed with step portions 13° and 13' on both inner sides of the receptacle-like electrical contact portion 12. Then, the step portions 13, 13'
The tongue piece 16 is folded back from the front end of the bottom wall 14 located below the gap into the electrical contact part 12 via the curved part 15, and a protrusion 17 is formed on the tongue piece 16. Step portion 13 and upper wall 18, 18' of receptacle-like electrical contact portion 12
It is designed to fit into the perforated lower part of the tab-shaped electrical contact part 6 of the mating electrical connector 3 which is held between the two, and to release it by pushing down the tongue piece 16.

The bottom wall 14 has a connector housing 11, which will be described later, in the center.
An engagement hole 22 is formed to engage with a lance 21 projecting into the cavity 20 with some flexibility, and side walls 23, 23' are raised on both sides.

The side wall 23.23' rises to a suitable height and is bent outward to form the above-mentioned step 13.13' in this part.

The earth wall 18, 18' mentioned above rises from the side end of the part extending outward through the bent part of the side walls 23, 23', curves inward, and has a tongue piece 16 interposed in the middle of the tip. The stepped portions 13, 13' are opposed to the bottom wall 14 in the
The relative opposing interval in the vertical direction is made slightly narrower than the plate thickness at the electrical contact portion 6 of the mating electrical connector 3.

From the side walls 23, 23' of the receptacle-shaped electrical contact portion 12 to the earth wall 18, 18', there is a window 25, 25' for protruding outwardly the ears 24, 24' of the tongue piece 16, which will be described later.
is required to be drilled.

The tongue piece 16 has ear pieces 24, 24' protruding outwardly from both sides of the central part through the windows 25, 25'.
The proximal end side of the tongue piece 16 of the ear piece 24, 24' is curved downward.

A bottom wall 1 is provided at the rear of the electrical contact portion 12 which is omitted from the above-mentioned configuration.
An electric wire connecting portion 27 is formed through a pair of leg pieces 26 and 26' extending rearward from the electric wire connecting portion 27, which is perpendicular to the direction in which the electric contact portion 12 is fitted with the electric contact portion 6 of the mating electric connector 3.

The cavity 20 of the connector main body 2 that accommodates the electrical connector 8 having the above-described structure has the above-mentioned wire connection portion 27 at the rear.
A wire guide portion 29 for guiding and accommodating the wire 28 connected thereto is formed perpendicular to the axial direction of the connector body 2, and a front portion is provided for receiving the electric connector 6 of the mating electric connector 3. A socket portion 30 is formed.

On the other hand, a guide groove 31 is formed on each inner side surface of the circle to push down the ear pieces 24, 24 by the relative movement of the connector housing 11 and the electrical connector 8, and a free end is formed in the front part of the bottom wall 14 by a notch. A flexible lance 21 is formed.

The bottom surface of the guide groove 31 is formed to be flush with the top surface of the bottom wall 14, and the top surface is parallel to the bottom surface from the rear part to the center part and gradually slopes toward the bottom surface in the front part, and the slope surface 33 is formed in this part.
is formed.

A protrusion 34 extending in the axial direction is formed at the center of the front portion of the earthen wall of the cavity 20 .

The opening width of the socket part 30 differs through the upper and lower steps, and the upper part has a width corresponding to the width of the tab-shaped electrical contact part 6 into which the socket is inserted, and the lower part has a width corresponding to the width of the tab-shaped electrical contact part 6 into which the socket is inserted. 16
The spacing width corresponds to the width of the spacer.

To accommodate the electrical connector 8 in the connector housing 11 described above, the tabs 24, 24' are guided into the guide grooves 31, as shown in FIG.
4 is interposed therebetween, and the engagement hole 22 is flexibly engaged with the lance 21.

With respect to the electrical connector 8 accommodated in the connector housing 11 in such a state, the tab-shaped electrical contact portion 6 of the mating electrical connector 3 is connected to the protrusion 17 of the tongue piece 16 by the piercing lower. It is locked and can be unlocked by moving the connector housing 11 in the direction of separating it from the mating electrical connector 3.

That is, the inclined surface formed on the upper wall of the guide groove 31 by moving the connector housing 11 in the direction of separating it from the electrical connector 3 within the flexibility of the engagement hole 22 and the lance 21 that are in an engagement relationship. 33 moves while contacting the curved portions of the ear pieces 24, 24', pushes down the ear pieces 24, 24', detaches the protrusion 17 from the piercing lower, and removes the electrical connector 3.
and 8 to unlock each other.

Accordingly, in the present invention, at least one electrical connector having a receptacle-like electrical contact portion having the above-described configuration and operation is provided in a multi-pole connector connected to a headlamp.
The design allows for more than one connector to be accommodated and used for connection with the electrical connector provided on the headlamp, so that the electrical and mechanical connection between the headlamp and the multi-pole connector can be reliably established. It will become.

In addition, the multi-pole connector, which is mechanically connected and locked to the headlamp, can be easily unlocked by simply pulling the connector housing away from the headlamp, making wiring work easier. Moreover, it also has the advantage that maintenance management such as inspection in the event of a failure can be easily handled.
