The present invention relates to a terminal block including a holding spring piece for fixing the above-mentioned attachment part on a base.

[Background Art] In order to fix the retaining spring piece to the base in a conventional terminal block of this type, as shown in FIG. The retaining spring piece 3 is fixed to the base 2 by forming a pair of locking claw pieces 21 spaced apart from each other and inserting these into a mounting hole 22 formed in the base 2. Therefore, once the retaining spring piece 3 is inserted into the base 2, it cannot be removed from the base 2, and the length of the retaining spring piece 3 cannot be changed. It could not be used for the attachment part 1 of Furthermore, when used for a mounting part 1 that is attached without using the retaining spring piece 3, the retaining spring piece 1 gets in the way, which is inconvenient.

[Purpose of the invention] The present invention was made in view of the above points, and its main purpose is to construct a retaining spring piece by detachably connecting a plurality of spring pieces. Accordingly, the length of the holding spring piece can be made variable, and the holding spring piece can be removed when it is not needed.

[Disclosure of the invention] Hereinafter, embodiments of the invention will be described based on the drawings. The terminal block with the retaining spring piece according to the present invention is basically a mounting part 1 such as a relay or a time-limited relay.
The terminal block is equipped with a base 2 on which is disposed on the surface thereof, and a retaining spring piece 3 for fixing the mounting part 1 on the base 2 to the base 2. It is constructed by connecting a plurality of spring pieces 4, 5 along the longitudinal direction, and has a first engaging part 6 provided on one of the pair of adjacent spring pieces 4, 5 and a first engaging part 6 provided on the other. The second engaging portion 7 is detachably engaged with the second engaging portion 7.

As shown in FIG. 2, the terminal block is constructed by attaching a pair of holding spring pieces 3 to a base 2, and a terminal portion 15 is provided at the end of the base 2.
As shown in FIG. 10, a socket part 17 is formed on the upper surface of the base 2, and a mounting part 1 accommodated in a box-shaped hanging such as a relay or a time-limited relay disposed on the base 2. A terminal 16 protruding from the socket is inserted into this socket portion 17. The socket portion 17 is electrically connected to the terminal portion 15. As shown in FIG. 3, the holding spring piece 3 is constituted by upper and lower spring elements 4 and 5, and the lower spring element 4 and the upper spring element 5 are telescopically connected. The lower spring element piece 4 is formed with a slide hole 9 running in the vertical direction as a first engagement part 6, and the upper spring element 5 is formed with an engagement projection piece as a second engagement part 7 that engages with the slide hole 9. 11 is formed. An engaging protrusion 11 is formed at the tip of the engaging protrusion 11 and has a locking flange 10 that is wider in left and right width than the slide hole 9. When the piece 11 is inserted, the opening periphery of the slide hole 9 is held between the locking collar 10 and the upper spring element 5, so that the lower spring element 4 and the upper spring element 5 are connected. Ru. Therefore, the upper spring piece 5 can freely slide up and down with respect to the lower spring piece 4. The locking collar 10 is formed so that the length in the longitudinal direction of the holding spring piece 3 is smaller than the length in the width direction of the holding spring piece 3, and the slide hole 9 has a wide width in the left and right at the center in the longitudinal direction. A loose attachment/detachment portion 12 is formed. The width of the detachable part 12 is formed to be approximately equal to the length of the locking collar 10 in the longitudinal direction of the holding spring piece 3, and the length of the detachable part 12 is the length of the locking collar 10 in the width direction of the holding spring piece 3. is formed approximately equal to . As shown in FIGS. 4 to 6, the upper spring piece 5 is disposed approximately perpendicular to the lower spring piece 4, and the locking collar 10 is inserted into the detachable part 12. By rotating approximately 90 degrees, the lower spring element 4 and the upper spring element 5 are combined, and the lower spring element 4 and the upper spring element 5 are separated by the reverse operation. It is also possible. The lower end portion of the lower spring piece 4 is bent in the thickness direction of the lower spring piece 4 and faces diagonally downward to form a locking piece 21 . Furthermore, a claw piece 19 extends obliquely upward from the lower edge of the opening of the slide hole 9 in substantially a straight line with the locking piece 21 . A holding piece 20 is formed at the upper end of the upper spring piece 5, and a mounting part 1 such as a relay is placed on the base 2, and this holding piece 20 is attached as shown in FIG. The mounting component 1 can be fixed onto the base 2 by fitting into a recess 22 formed on the top surface of the component 1. As shown in FIG. 10, a storage hole 8 is opened in the upper surface of the base 2, and the lower end portion of the holding spring piece 3 is stored in the storage hole 8 so as to be able to move forward and backward. The distance between the tip of the locking piece 21 formed at the lower end of the lower spring element piece 4 and the tip of the claw piece 19 is formed to be slightly larger than the width of the storage hole 8. 21 and the claw piece 19 are adapted to come into pressure contact with the inner circumferential surface of the storage hole 8. Thereby, the holding spring piece 3 can be held at an arbitrary height position, and the upper end portion of the holding spring piece 3 is inclined in a direction gradually moving away from the attachment part 1. That is, when the holding piece 12 is not engaged with the recess 17 formed on the top surface of the mounting part 1, the holding piece 12 is separated to the outside of the mounting part 1, and the mounting part 1 cannot be attached to or removed from the base 2. This prevents the holding spring piece 3 from getting in the way. Furthermore, as shown in FIGS. 2 and 10, the left and right retaining spring pieces 3 are disposed at shifted positions in the front and back of the base 2, so that when a plurality of bases 2 are arranged in the width direction, The holding spring pieces 3 provided on a pair of adjacent bases 2 are prevented from colliding with each other. The retaining spring piece 3 is not engaged with the mounting part 1, and its tip end is attached to the base 2 adjacent to the base 2.
Be careful not to touch the mounting parts 1 placed above.
Its inclination angle is set.

With the above configuration, the holding spring piece 3 is constructed in a form in which the upper and lower spring pieces 4 and 5 are telescopically connected.
In addition, the upper and lower spring pieces 4 and 5 are detachably connected. Therefore, the length of the holding spring piece 3 can be adjusted according to the height of the attachment part 1 on the base 2, and one terminal block can be used for various attachment parts 1. Furthermore, if the retaining spring pieces 3 are not needed, either remove the upper and lower spring pieces 4 and 5, or
Alternatively, it is possible to install the mounting part 1 which can be stored in the storage hole 8 and does not require holding by the holding spring piece 3. In addition, the holding spring piece 3
Since the holding piece 20 protrudes outside the holding hole 8 when it is retracted and stored in the holding hole 8, the holding piece 20 can be used as a knob when pulling out the holding spring piece 3. When the retaining spring piece 3 is pulled out to the maximum extent, the claw piece 19 formed at the lower end of the lower spring piece 4 is engaged with a locking protrusion 18 formed on the opening edge of the storage hole 8 to prevent it from coming off. It is something that

In the above example, the slide holes 9 were formed in a series, but as shown in FIG. The portion 12 may also be formed. In this case, the upper spring piece 5 can be held in either the upper or lower position, and which of the two slide holes 9 should be engaged with the engagement protrusion 11 of the upper spring piece 5. By selecting whether or not to hold the holding spring piece 3, the entire length of the holding spring piece 3 can be made variable. In this example, the two side edges of the slide hole 9 are completely connected at the part that divides the two slide holes 9, but as shown in FIG. It can produce similar effects.

[Effects of the invention] As described above, in the present invention, the holding spring piece is constructed by connecting a plurality of spring pieces along its longitudinal direction, and is provided on one of the pair of adjacent spring pieces. Since the first engaging part and the second engaging part provided on the other side are removably engaged, the length of the holding spring piece can be made variable, and the holding spring piece is not required. Sometimes this can be removed, so that the length of the retaining spring piece can be adjusted for fittings of different heights, allowing one terminal block to be used for various fittings. It is something. Furthermore, if the spring pieces are uncoupled, the holding spring pieces do not get in the way even when using a mounting component that can be attached without using the holding spring pieces.
