The internal space 12 corresponding to the back side of the housing 10 is provided with a structure for temporarily supporting the terminal 26 to be described below. That is, the inner space 12 is formed with a support partition 16. The support partition wall 16 is formed so as to cross the rear end center of the inner space 12 vertically. A middle portion of the support partition 16 is opened. A plurality of terminal channels 18 are formed in the upper and lower support partition walls 16 corresponding to the open portion. A terminal (26) is installed so as to pass through the terminal channel (18) and its installation position is guided.

A guide rib 20 protrudes from an inner surface of one side of the inner space 12 corresponding to the upper end of the support partition wall 16. The guide ribs 20 serve to guide the installation position of the molding cover 30 to be described below.

Mounting pieces 22 are formed on both sides of the outer surface of the housing 10 so as to protrude in opposite directions. A mounting hole (24) through which a screw is passed is formed in the mounting piece (22). The mounting pieces 22 are formed on both sides of the housing 10 so as to be symmetrical to each other. The mounting pieces 22 are formed symmetrically with respect to each other and are mounted in the product, thereby preventing the connector from being displaced when the plug of the earphone is inserted through the inlet 14. Therefore, it is possible to prevent leakage of water through the portion where the connector is installed.

A packing 26 is provided on the front end side of the housing 10 so as to surround the outer surface thereof. When the connector of the present invention is installed in a product such as a portable terminal or the like, the packing 26 is closely attached to components constituting the external appearance of the portable terminal and plays a waterproof function.

A plurality of terminals 28 are installed in the housing 10. The terminals 28 have various functions such as contact with an earphone plug, grounding, and the like. The ends of the terminals 28 are located in the inner space 12 of the housing 10 and the rear ends thereof protrude out of the housing 10. The terminal 28 thus exposed is mounted on a printed circuit board and electrically connected to the outside. In the present embodiment, there are a plurality of terminals 28, which are not the subject of the present invention, and thus the functions of the terminals 28 are not described.

And a molding cover 30 is provided facing the support partition wall 16 of the inner space 12. [ The molding cover 30 prevents the resin from flowing into the inner space 12 through the rear of the housing 10 during injection molding. Of course, the molding cover 30 also serves to support the terminals 28.

The molding cover 30 is formed in a shape corresponding to the cross section of the internal space 12, and in this embodiment, it is a rectangular plate. A guide groove 32 is formed at one side edge of the molding cover 30. The guide rib (20) is seated in the guide groove (32). The molding cover 30 is not in close contact with the support partition wall 16 but is opposed to each other with a part of the terminal being interposed therebetween.

A plurality of assembly ribs 34 protrude from one side surface of the molding cover 30. The terminals 28 pass between the assembly ribs 34 and between the assembly ribs 34 and the inner surface of the housing 10.

The first terminal penetration portions 38 are formed in portions corresponding to the spaces between the assembly ribs 34 so as to penetrate the molding cover 30. Some of the terminals 28 pass through the first terminal penetrations 38. This is well illustrated in FIG.

An end column 36 is formed at both ends of the opposite edge of the molding cover 30 where the guide groove 32 is formed. The end column (36) is elongated in the molding cover (30), and its tip end is seated on the inner surface of the inner space (12). A spacer rib (40) protrudes from an intermediate portion of the opposite edge of the edge where the guide groove (32) is formed. The tip end of the spacer rib 40 protrudes to the same extent as the end of the end column 36. The spacer ribs 40 serve to form a predetermined gap between the inner surface of the inner space 12 and one side edge of the molding cover 30. Of course, the end column 36 also plays the same role. A second terminal penetration portion 42 is formed between the space between the spacer ribs 40 and the end column 36, that is, between the molding cover 30 and the inner surface of the inner space 12. [ The terminals 28 pass through the second terminal penetration portion 42 as well. This is well illustrated in FIG.

On the other hand, when the waterproof connector is finally made, the rear of the housing 10 is closed as shown in Fig. The rear of the housing 10 is closed by the housing back plate 44 as shown in Fig. The housing back plate (44) is integrally formed with the housing (10). Of course, when the housing 10 is initially formed, the housing back plate 44 is not present. After the terminal 28 and the molding cover 30 are installed, (44) are integrally formed on the housing (10). Therefore, the structure of the housing back plate 44 shown in FIG. 2 is made separate from the housing 10 for convenience, and is not actually separate from the housing 10.

Hereinafter, manufacturing and use of a waterproof connector for an earphone according to the present invention having the above-described configuration will be described.

First, the manufacture of a waterproof connector for an earphone of the present invention will be described. In the present invention, the housing 10 as shown in FIG. 2 is first manufactured by injection molding, and the terminals 28 are installed in the housing 10. When the installation of the terminal 28 is completed, the molding cover 30 is inserted into the inner space 12 through the rear of the housing 10 to face the support partition wall 16. Such a state is shown in Fig.

5 is installed in a mold for insert molding, and a portion corresponding to the housing back plate 44 is integrally formed on the rear side of the housing 10. That is, resin is injected into the rear of the housing 10 of the assembly shown in FIG. 5 so that the housing back plate 44 is formed integrally with the housing 10. A waterproof connector thus formed is shown in Fig.

When the packing 26 surrounding the tip of the waterproof connector thus formed is provided, the waterproof connector as shown in Fig. 1 is completed. The finished waterproof connector is mounted on the printed circuit board used in the portable terminal to electrically connect the rear end of the terminal 28

When the printed circuit board on which the waterproof connector is mounted is installed inside the portable terminal and the components constituting the external appearance of the portable terminal are assembled, the inlet 14 of the waterproof connector is exposed to the outside of the portable terminal. At this time, the waterproof connector is firmly fixed to the portable terminal by fixing the mounting piece 22 protruding from both sides of the housing 10 to a part forming the outer appearance or skeleton of the portable terminal. In other words, the mounting piece 22 is provided symmetrically with the outer surface of the housing 10, so that when the mounting pieces 22 on both sides are fixed, the housing 10 can be more firmly fixed to the portable terminal .

The plug of the earphone is inserted into the waterproof connector of the portable terminal through the inlet 14 and the plug of the earphone is electrically contacted with the terminal 28 to transmit a voice signal to the earphone so that the earphone can be heard by the user. do.

In this state, even if the plug of the earphone is inserted into the housing 10 through the inlet 14, the housing 10 is prevented from being tripped. This is because the packing 26 provided around the outer surface of the front end of the housing 10 can be reliably maintained in close contact with the component of the portable terminal, thereby ensuring the waterproof function.

Since the housing back plate 44 is integrally formed on the back surface of the housing 10 by insert injection, the terminals 28 are integrated with the housing back plate 44 and there is no gap therebetween The water does not enter the inside of the waterproof connector through the portion where the terminal 28 is installed, so that the waterproof can be surely achieved.

It is to be understood that the scope of the present invention is not limited to the above-described embodiments but is defined by the scope of the claims, and those skilled in the art can make various modifications and alterations within the scope of the claims It is self-evident.

For example, although the molding cover 30 is used in the illustrated embodiment, it is possible to fix the terminal 28 to the housing 10, and the resin for forming the housing back plate 44 is made of the above- It is not necessary to use the molding cover 30 as long as it can be prevented by the partition wall 16 or the like from entering the inner space 12.
