Conventionally, this type of connection between electric wires has been performed by making a terminal connection such as a clasp connection or a grip connection, and then completing the connection with tape. However, when connecting in this way, there has been a problem that work efficiency is poor. Therefore, a connector was developed that allows connections by simply inserting the wire. This connector has a cylindrical terminal frame fitted inside a cylindrical casing with a bottom, a plurality of locking springs are arranged inside the terminal frame, and the opening of the casing is closed with a cover. It is configured with a wire insertion hole. However, since the terminal frame used in this connector is made of copper or brass and is expensive, it has been desired to make the terminal frame thinner.

In these figures, reference numeral 1 denotes a casing in the shape of a rectangular cylinder with a bottom, and a wire insertion hole 2 is formed in the bottom of the rectangular cylinder with a bottom. Reference numeral 3 denotes a rectangular cylindrical terminal frame made of copper or brass. Reinforcing ribs 4 are provided on the upper and lower surfaces of the terminal frame along the opening edges, and reinforcing ribs 4 are provided on the inner surfaces of the upper and lower surfaces in the axial direction of the terminal frame 3. A plurality of positioning ribs 5 are provided along the line. This positioning rib 5 functions to position an electric wire (not shown) inserted through the electric wire insertion hole 2 of the casing 1. 6 is a plurality of locking springs, each of which has one end and the other bent;
One end is formed as a locking piece 7, and the other end is formed as a pressing piece 8. These locking springs 6 are sequentially inserted into the terminal frame 3 at predetermined intervals and fixed, with their locking pieces 7 corresponding to the wire insertion holes 2 of the casing 1, as shown in the figure. Reference numeral 9 denotes a cover that closes the opening of the casing 1, and has a wire end receiving recess 1 on its inner surface.

れる。 This connector is constructed by fitting a terminal frame 3 into a casing 1 as shown by the arrow, then inserting locking springs 6 vertically into the terminal frame 3 alternately, and then closing the opening of the casing 1 with a cover 9. Can be assembled.
Connection between electric wires using the thus assembled connector is performed as follows. That is, this is carried out by peeling off the coating on the end of the electric wire to expose the core wire, and inserting the exposed core wire into the wire insertion hole 2 of the casing 1 as shown in FIG. 3. In this case, the locking piece 7 is bent by inserting the core wire 11, and when the core wire 11 is further inserted from this state, the pressing piece 8 is also bent and the core wire 11 is pressed against the terminal frame 3. In this way, each electric wire 1 is inserted into the electric wire insertion hole 2 provided in the casing 1.
Two core wires 11 are inserted and connected via the terminal frame 3.

一部防止される。 In this case, since a positioning rib 5 is provided inside the terminal frame 3, when inserting the core wire 11, the rib 5 allows the core wire 11 to be inserted in the proper position as shown in FIG. Become. Since a reinforcing rib 4 is provided on the outer circumferential portion of the terminal frame 3 along a direction perpendicular to the axial direction, the core wire 11 is inserted through the reinforcing rib 4 and the locking piece 7 and the pressing piece 8 Even when pressed against the terminal frame 3, the upper and lower parts of the terminal frame 3 are prevented from bulging. That is, in the absence of such reinforcing ribs 4, the insertion of the core wire 11 causes the upper and lower surfaces of the terminal frame 3 to swell as shown by chain lines as shown in FIG. However, since the terminal frame 3 of the connector of this invention is provided with reinforcing ribs 4,
This action prevents the upper and lower surfaces of the terminal frame 3 from bulging. That is, by providing the reinforcing ribs 4 in this manner, the terminal frame 3 can be made thinner. Incidentally, bulging of the upper and lower surfaces of the terminal frame 3 is also partially prevented by the positioning ribs 5.

ことにより上記のような効果を得るようにするた
め、芯線挿入が円滑に行われる。 Note that the wire insertion hole 2 provided at the bottom of the casing 1 may be configured as shown in FIGS. 6 and 7. That is, the peripheral edge of the hole wall of the wire insertion hole 2 of the casing 1 is formed into a tapered surface 13 as shown in the figure, and a small protrusion 14 is formed on the hole wall portion of the wire insertion hole 2 near the center of the casing 1. It may also be formed. By doing so, it becomes easy to insert the core wire 11 of the electric wire 12 into the electric wire insertion hole 2 as shown by the chain line in FIGS. Due to the small protrusions 14, the contact of the core wire 11 with the terminal frame 3 is not impaired even if a downward force is applied to the electric wire 12. That is, if this small protrusion 14 is not present, as shown in FIG. 10, when an external force is applied to the electric wire 12 as shown by the arrow, the electric wire 12 will change its position as shown by the chain line with point C as a fulcrum, so the core wire 11 separates from the terminal frame 3 as shown by the chain line. However, as shown in FIGS. 6 and 7, a small protrusion 14 is formed on the wall of the wire insertion hole 2.
When formed, the core wire 11 is held down by the small projections 14, so that the core wire 11 remains in contact with the terminal frame 3 even if an external force is applied. In this case, instead of making the entire wire insertion hole 2 smaller, small protrusions 14 are provided on the hole wall to obtain the above effect, so that the core wire can be inserted smoothly.

need to be formed.
この考案の接続器は、以上のように構成されて

つてコストを著しく引き下げうるようになる。
Since the connector of this invention is constructed as described above, the terminal frame can be made thinner, thereby significantly reducing costs.

ても抜けたり緩んだりすることがないのである。 In particular, since reinforcing ribs are provided along the direction perpendicular to the axial direction of the terminal frame, even if a core wire is inserted into the wire insertion hole and is strongly pressed against the terminal frame by a locking piece or a pressing piece, the terminal frame will not hold. The top and bottom surfaces will not bulge and deform. In other words, flat objects such as conventional terminal frames are easily deformed, so
There were problems in which the pressing force against the core wire decreased, resulting in poor electrical connection performance and the core wire easily coming off during use, but with this invention, the reinforcing ribs prevent deformation of the terminal frame. Therefore, the core wire can be strongly pressed against the terminal frame to ensure electrical connection, and even if external force is applied to the core wire, it will not come off or come loose.
補強リブの強度が充分にあれば、その他の部分
はそれほど強度を必要としないので薄肉であつて

子枠全体としての薄肉化を図れ、その結果、接続
器の小型化およびコスト低減も可能になる。 As long as the reinforcing ribs have sufficient strength, other parts do not require much strength, so there is no problem with thin walls.Compared to conventional terminal frames, the terminal frame as a whole can be made thinner, and as a result, It also becomes possible to reduce the size and cost of the connector.
なお、上記補強リブとは別に、端子枠の内部に
位置決め用のリブを設けておくと、鎖錠ばねの配
挿入時の位置決め効果や電線挿入時の位置決め効
果も得られるようになる。 In addition to the reinforcing ribs, if a positioning rib is provided inside the terminal frame, a positioning effect when inserting and inserting a locking spring and a positioning effect when inserting an electric wire can also be obtained.
