connector structure

technical field

The utility model relates to a connector structure, in particular to a connector structure in which a terminal has a snap ring that can buckle a snap post of a cover plate.

Background technique

Please refer to FIG. 1A and FIG. 1B . FIG. 1A and FIG. 1B are conventional connectors. As shown in FIG. 1A , there are a plurality of through slots (not shown) on the back of the buckle body 10 in the conventional connector, and locking slots (not shown) are provided on both sides. Therefore, when the cover plate 12 with the fixing column that can be inserted into the card engine slot is provided on both sides, after the fixing column is inserted into the card engine slot, the cover plate 12 can be opened as shown in FIG. 1B but will not be engaged with the buckle The body 10 is separated. A plurality of locking teeth 12 a are disposed on the bottom edge of the cover plate 12 .

The cable space formed between the plurality of inserting slots of the fastening body 10 and the locking slot is mainly for inserting a cable (not shown). After the cable is inserted, the cover plate 12 is covered behind the space for placing the cable, so that the cable contact portion of the cable is in contact with the terminal contact portion.

Please refer to FIG. 2 . FIG. 2 is a three-dimensional cross-sectional view of the connector in FIG. 1 . Since, as shown in FIG. 2 , there is a fastening column 12b between the locking teeth 12a, so when the terminal 30 is inserted along the through slot of the fastening body 10, the second part extended from the base portion 30a of the terminal 30 A snap arm 30c snaps onto the snap post 12b of the cover 12 .

Please refer to FIG. 3A , FIG. 3B , FIG. 3C and FIG. 3D , which are cross-sectional views of the connector in FIG. 1 . As shown in FIG. 3A , the terminal 30 has been inserted into the buckle body 10 . Next, as shown in FIG. 3B , after the cover plate 12 is opened, it is easy to cause the cover plate 12 to be slightly detached because the first locking arm 30 c of the terminal 30 cannot tightly fasten the locking post 12 b. Then, the cable 40 is inserted into the above-mentioned space for placing the cable, and then the cover plate 12 is pressed down as shown in FIG. 3C . Finally, since the cover 12 has been slightly detached as shown in FIG. 3B , it is easy to cause the cover 12 to be completely detached when the cover 12 is pressed down after the cable 40 is inserted. In this way, the cable contact portion of the cable 40 is not in good contact with the contact portion of the contact arm 30b, resulting in poor contact.

The above problem of loosening of the cover plate 12 and the resulting poor contact will be more serious if the cable 40 has a large number of corners, because the cover plate 12 is easily deformed due to heat.

Contents of the invention

The main purpose of the present invention is to provide a connector structure, through which the terminals can form a snap ring, so that the terminals can be tightly engaged with the cover to prevent the cover from loosening.

Based on the above purpose, the connector structure of the present invention includes a fastening body, a cover plate and a terminal. The fastening system has a plurality of through slots on its back, and there are locking slots on both sides. The cover plate is provided with fixing columns on both sides thereof which can be inserted into the locking groove, and a plurality of locking teeth are arranged on the bottom edge of the cover plate, and fastening columns are arranged between the locking teeth. The terminal system has a base, and a first snap arm, a second snap arm and a contact arm extend from the base. A terminal contact portion protrudes from the front end of the contact arm. Engagement grooves are respectively recessed at the front ends adjacent to the first engaging arm and the second engaging arms and at opposite inner sides. The engaging grooves constitute an engaging ring with an opening and capable of fastening the fastening post.

The advantages and spirit of the present invention can be further understood through the following specific embodiments and accompanying drawings.

Detailed ways

Please refer to FIG. 4 , which is a schematic diagram of the terminal of the present invention. As shown in FIG. 4 , the terminal 50 is an integrally formed metal sheet. Like the conventional terminal 30 , the terminal 50 of the present invention extends from the base 50 a with a first engaging arm 50 c , a second engaging arm 50 d and a contact arm 50 b.

The biggest difference between the terminal 50 of the present invention and the conventional terminal 30 is that engaging grooves 50e and 50f are recessed on the inner sides adjacent to the front ends of the first engaging arm 50c and the second engaging arm 50d. The engaging grooves 50e and 50f are formed with openings and can fasten the engaging post 12b as shown in FIG. 2 .

Fig. 5A, Fig. 5B and Fig. 5C are combined schematic diagrams of the connector of the present invention. As shown in FIG. 5A , the terminal 50 of the present invention is inserted into the slot 10 a on the back of the fastening body 10 to form a combination as shown in FIG. 5B . Next, as shown in FIG. 5C , the cover plate 12 with the fastening post 12 b is combined with the fastening body 10 so that the first fastening arm 50 c and the second fastening arm 50 d fasten the fastening post 12 b. However, it is also possible to combine the cover plate 12 with the fastening body 10 first, and then insert the terminals 50 into the fastening body 10 .

Since the terminal 50 is made of metal, the first locking arm 50c and the second locking arm 50d of the terminal 50 are elastic to expand outward. Therefore, as shown in FIG. 5C, when the front ends of the first snap arm 50c and the second snap arm 50d contact the snap post 12b, they will be slightly spread out, and when the first snap arm 50c and the second snap arm The engagement grooves 50e and 50f formed between the arms 50d will recover when they substantially enclose the engagement post 12b. That is to say, when the fastening post 12b is surrounded by the fastening ring formed by the fastening grooves 50e and 50f, the first fastening arm 50c and the second fastening arm 50d will no longer have the fastening post 12b. When it is stretched out, it returns to its original shape due to its metal elasticity.

Fig. 6A, Fig. 6B and Fig. 6C are combined schematic diagrams of connecting cables of the connector of the present invention. After completing the connector as shown in FIG. 5C , insert the cable 40 into the connector as shown in FIG. 6A . After the cable 40 is completely inserted into the cable space of the fastening body 10 , the cover 12 needs to be pressed down as shown in FIG. 6B . Finally, when the cover plate 12 is completely pressed down, the terminals 50 are still tightly clamped to the fastening column 12b of the cover plate 12 during the process of opening or closing the cover plate 12, so that the wiring of the cable 40 The contact portion can have good contact with the contact portion of the contact arm 50b.

Through the above detailed description of the preferred embodiments, it is hoped that the features and spirit of the present utility model can be described more clearly, and the scope of the present utility model is not limited by the preferred embodiments disclosed above. On the contrary, the purpose is to cover various changes and arrangements with equivalents within the scope of the patent scope of the utility model.
