The present invention relates to a female connector coupled to the board to have a multi-pole power connection function, and is particularly useful for instrument panel power connection of a vehicle, which is accompanied with severe vibration at all times by exerting excellent board binding force and contact reliability. The present invention relates to a female connector for connecting a vehicle dashboard power supply.

In the past, various types of connectors suitable for the function, use, and coupling structure of an applied object, such as for connecting power supplies of various electronic devices or acoustic devices, have been developed and used selectively. The specific structure of the connector that can be used properly has not been made, and the existing connector developed for other purposes is applied to the vehicle dashboard. Due to the inability to expect a suitable board binding force, a malfunction occurred due to contact failure of the terminal connected to the board within a short period of time, and in severe cases, even when the connector itself detached from the board. There was this.

In order to alleviate this closed end somewhat, a type of connector has been developed in which a plurality of terminal pins are penetrated in a predetermined arrangement from the inside of the substrate, and a female connector formed to be coupled to the terminal pins from the outside is installed. In addition, the board bond strength was not higher than expected, so the contact reliability of the terminal pin was extremely low, and the detachment of the connector could not be completely excluded.

The present invention has been devised to effectively solve this problem in view of the above-mentioned conventional problems, and install a diaphragm at an appropriate interval in the housing so that a plurality of terminal coupling holes in mutually isolated state are provided, and fastening fixing parts are extended on both sides of the housing. It is formed to be firmly fixed to the board by screwing, while the housing bottom has a number of grooves to be addressed to obtain the gas and heat release improvement effect when soldering welding between the terminal hole of the board and the terminal inserted into the terminal hole. Therefore, the welding is made in a very good state, and the bonding force between the terminal and the substrate is relatively increased, thereby exerting a high contact reliability without unintentionally flowing or deviating from any vibration applied in the installation state. Providing a female connector that always performs its unique functions accurately When in on the basis of the configuration and the installation status and operational effects thereof according to the appended drawings described in detail that for this purpose as follows.

As shown in FIG. 1 and FIG. 2, a plurality of terminal coupling holes 3 are provided in mutually isolated state by installing diaphragms 2 at predetermined intervals inside the housing 1 of a rectangular shape. On both sides of (1), a fastening fixing part (4) through which threaded holes (4a) are formed is extended, and a plurality of positioning grooves (6) are provided in the central part of the inner wall of the housing (1) which forms the terminal coupling hole (3). At the same time, the guide protrusion 7 and the lock piece 8 protrude from the outside thereof, and the reverse insertion prevention end 9 of the male connector 10 is provided at the rear corner of the coupling hole 3 located at both ends. In the formed female connector (A), the front and rear portions of each coupling hole (3) inside the bottom of the housing (1) in the state exposed to the outside while the terminal 5 is arranged in a vertical arrangement, respectively At the same time, to the bottom surface of the housing 1, the groove portion 15 located on the same line as the respective terminals 5 is spoken. It is composed.

As shown in FIG. 4, the female connector A of the present invention having such a configuration has a terminal 5 formed through the terminal hole 12 in the substrate 11 to be installed, and is exposed below the housing 1. ) Is firmly fixed to the substrate 11 by fastening the screws 14 to the screw holes 4a of both fastening fixing parts 4 while the housing 1 is seated and installed on the upper surface of the substrate 11 while being inserted. After the soldering is welded between each terminal 5 exposed to the bottom of the substrate 11 and the terminal hole 12, the present design is connected to the substrate.

In the installation process of the present invention, the housing 1 is firmly installed on the substrate 11 by screwing to the fastening fixing part 4, while solder welding is performed from the bottom of the substrate 11 At the time of welding, the gas or heat inevitably generated during the welding is smoothly discharged through the recessed part 15 positioned on the same line as the terminal 5, and thus the soldering state is made very good. The binding force of (5) is to be relatively increased. After the female connector A of the present invention is attached to the substrate 11 in this state, as shown in FIG. 3, the respective engaging holes 3, the lock pieces 8, and the positioning grooves ( 6) and the male connector 10 of the predetermined type corresponding to the reverse insertion prevention end 9 is to be connected to the power supply bar, in which case the male connector 10 has a predetermined type of connection terminal 16 By connecting to the terminal 5 in the coupling hole 3, respectively, the power supply state is made.

The female connector (A) of the present invention as described above to be firmly fixed on the substrate through the fastening fixing part of the both sides of the housing, while forming a groove portion located on the same line as the terminal on the housing bottom when welding work By allowing the gas or heat to be discharged very smoothly, the soldering is in very good condition to increase the binding force with the substrate, so that high contact can be made without moving or escaping by the vibration inevitably generated during the operation of the vehicle. It always works correctly while maintaining reliability, which is an advantageous design that can be very usefully applied for power connection of vehicle dashboards that require accurate measurement.
