Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The drawings are only schematic and may not be realistic. The following embodiments are intended to exemplify apparatuses and methods for embodying the technical ideas of the present invention, and the configurations are not intended to be specific to the following. That is, the technical idea of the present invention can be variously modified within the technical scope described in the scope of the present invention.
(Structure)
An embodiment is a connection terminal board capable of holding a ferrule terminal with a collar portion inserted into a housing, wherein the housing includes: a first surface orthogonal to an insertion direction of the ferrule terminal; a second surface orthogonal to the insertion direction, having a step with the first surface, and disposed on the insertion direction depth side of the first surface; an insertion hole through which the ferrule terminal can be inserted, the insertion hole penetrating from the second surface to the inside of the housing along the insertion direction; and an abutting portion formed on an inner peripheral surface of the insertion hole, the ferrule terminal being prevented from being further inserted by abutting against a front end of the collar portion when the ferrule terminal is inserted, the step being set such that a root end of the collar portion is disposed within a range between the first surface and the second surface when the front end of the collar portion abuts against the abutting portion.
Fig. 1 is a perspective view of the connection terminal plate.
In the following description, for convenience of description, three directions orthogonal to each other in space are referred to as a width direction, a longitudinal direction, and a depth direction.
The connection terminal board 11 is a terminal receptacle for connecting the relay with an external circuit. A primary-side terminal portion 12 for a coil terminal to which a primary-side lead wire can be connected is formed on one end side in the longitudinal direction. At the center in the vertical direction, for example, a relay terminal portion 13 to which a relay having 4-pole contacts can be connected is formed. On the other end side in the longitudinal direction, a secondary-side terminal portions 14 for common terminals, a contact terminals, and b contact terminals are formed to be connectable to secondary-side leads. The primary terminal portion 12, the relay terminal portion 13, and the secondary terminal portion 14 are integrally formed by a housing 15.
In the housing 15, the relay terminal portion 13 is disposed on the upper surface on the near side in the depth direction at a position further to the depth direction than the primary terminal portion 12 and the secondary terminal portion 14.
The primary terminal portion 12 has a spring-type terminal structure, and a plurality of wire insertion holes 21 into which lead wires can be inserted in the depth direction are formed in the upper surface of the housing 15. Two wire insertion holes 21c and 21d are formed as one polarity on one end side in the width direction, and two wire insertion holes 21a and 21b are formed as the other polarity on the other end side in the width direction. Therefore, the primary-side terminal portion 12 has a total of 4 wire insertion holes 21. Two wire insertion holes 21 having the same polarity are arranged in a staggered manner in both the width direction and the longitudinal direction. A plurality of tool insertion holes 22 into which a tool can be inserted in the depth direction are formed in the upper surface of the housing 15. The tool insertion holes 22 are provided one for each of the wire insertion holes 21a to 21d, and are disposed on the other end side in the longitudinal direction than the wire insertion holes 21a to 21 d. Therefore, the primary-side terminal portion 12 has a total of 4 tool insertion holes 22.
The relay terminal portion 13 has a plug-in type terminal structure, and a plurality of plug insertion ports 23 into which a plug can be inserted in the depth direction are formed in the upper surface of the housing 15. Two plug insertion openings 23 are formed as coil terminals on one end side in the longitudinal direction. On the other end side in the longitudinal direction, three plug insertion ports 23 are formed in the longitudinal direction for the common terminal, the a-contact terminal, and the b-contact terminal, and four sets of three plug insertion ports are arranged in the width direction as one set. Therefore, the relay terminal portion 13 has 14 plug insertion ports 23 in total.
The secondary terminal portion 14 has a spring-type terminal structure, and a plurality of wire insertion holes 24 corresponding to 4 poles into which wires can be inserted in the depth direction are formed in the upper surface of the housing 15. The secondary terminal portion 14 has three stages in which the height in the depth direction decreases in order from one end side to the other end side in the longitudinal direction. In the upper stage, for example, two wire insertion holes 24a to 24h are formed for each 1 pole for a b-contact terminal, in the middle stage, for example, two wire insertion holes 24i to 24p are formed for each 1 pole for an a-contact terminal, and in the lower stage, for example, two wire insertion holes 24q to 24x are formed for each 1 pole for a common terminal. At each stage, two wire insertion holes 24 (e.g., 24a and 24b) of 1 electrode are arranged to be staggered in both the width direction and the longitudinal direction. The six wire insertion holes 24 (e.g., 24a, 24b, 24i, 24j, 24q, and 24r) are arranged in the width direction by 4 poles as a group. Therefore, the secondary-side terminal portion 14 has 24 wiring holes 24 in total. A plurality of tool insertion holes 25 into which a tool can be inserted in the depth direction are formed in the upper surface of the housing 15. In each stage, the tool insertion holes 25 are provided in one-to-one correspondence with the wire insertion holes 24a to 24x, and are disposed at positions on one end side in the longitudinal direction of the wire insertion holes 24. Thus, the secondary-side terminal portion 14 has 24 tool insertion holes 25 in total.
Fig. 2 is a perspective view partially showing the internal connection terminal plate.
Since the primary-side terminal portions 12 and the secondary-side terminal portions 14 have substantially the same configuration, the secondary-side terminal portions 14 will be described as an example.
A blade spring 31 is provided inside the housing 15 on the back side in the depth direction of each plug insertion opening 23. The blade spring 31 includes a pair of spring pieces that are biased toward each other, and holds the plug inserted between the pair of spring pieces. Spring holders 32 (conductive terminal members) are provided on the back side in the depth direction of the wire insertion holes 24a to 24x, and the spring holders 32 are attached to an intermediate base 46 serving as a base member. The spring holder 32 includes a pressing surface 33 substantially parallel to the depth direction and the width direction, and a plate spring 34 (elastic member) for urging the pressing surface 33, and holds the lead wire inserted between the pressing surface 33 and the plate spring 34. At a position located further to the depth than the blade spring 31 and the spring holder 32, a relay conductive plate 35 for electrically connecting these members is provided. The relay conductive plate 35 has two sets for coil terminals, four sets for a common terminal, a contact terminal, and a contact terminal.
A ferrule terminal 18 having a ferrule portion 17 is crimped to the lead 16 inserted into the wire insertion hole 24. The ferrule terminal 18 is a rod-shaped crimp terminal for preventing the stranded wire from loosening and stabilizing the quality of electrical connection. The collar portion 17 has a tapered surface 19 formed on the tip end side thereof so as to have a smaller diameter toward the tip end 17a, and the diameter of the base end 17b is larger than the terminal portion 18a of the ferrule terminal 18.
Next, the structure of the wire insertion hole 24 will be described.
The same structure is applied to all the wire holes 24 formed in the secondary terminal portion 14, but here, the wire holes 24 formed in the lower stage are described as an example.
Fig. 3 is a cross-sectional view of a wire insertion hole (before insertion).
The housing 15 includes a first surface 41 orthogonal to the depth direction and a second surface 42 orthogonal to the depth direction, having a step d between the first surface 41 and the second surface, and disposed on the back side in the depth direction of the first surface 41.
Fig. 4 is a perspective view (before insertion) showing a step between the first surface and the second surface.
The first surface 41 is in contact with the side surface 26 on the other end side in the longitudinal direction in the housing 15. Therefore, the first surface 41 is not surrounded by the step d over the entire circumference, but is in a state where the other end side in the longitudinal direction is opened.
As shown in fig. 3, the wire insertion hole 24 includes a large diameter portion 43, an abutting portion 44, and a small diameter portion 45 in this order from the second surface 42 toward the inside of the housing 15. The diameter of the large-diameter portion 43 is slightly larger than the collar portion 17. The inner peripheral surface of the large diameter portion 43 is inclined by an angle θ in a direction opposite to the pressing direction toward the pressing surface 33, that is, in a direction opposite to the pressing direction toward the second surface 42. The contact portion 44 is a tapered surface having a diameter that decreases toward the depth side. The contact portion 44 has a taper angle in the depth direction of the housing 15 larger than an angle of the tapered surface 19 in the depth direction of the collar portion 17. The small diameter portion 45 of the housing 15 has a diameter smaller than the diameter of the tip 17a of the collar 17 and larger than the diameter of the terminal portion 18a of the ferrule terminal 18.
Fig. 5 is a cross-sectional view of a wire insertion hole (after insertion).
When the ferrule terminal 18 is inserted into the wire insertion hole 24, the plate spring 34 is pressed by the terminal portion 18a of the ferrule terminal 18 and elastically deformed. When the terminal portion 18a of the ferrule terminal 18 is inserted between the tip of the plate spring 34 and the pressing surface 33, the terminal portion 18a of the ferrule terminal 18 is pressed toward the pressing surface 33 by the elastic force of the plate spring 34, and displacement in the pull-out direction is suppressed. Here, for convenience of drawing, a state in which the ferrule terminal 18 with the collar portion 17 is not inclined is shown, and actually, since the terminal portion 18a of the ferrule terminal 18 is pressed toward the pressing surface 33 by the leaf spring 34, the ferrule terminal 18 with the collar portion 17 is inclined toward one end side in the longitudinal direction with respect to the depth direction and is in contact with the pressing surface 33. Therefore, the diameter of the large diameter portion 43, the angle θ, the taper angle of the contact portion 44, the diameter of the small diameter portion 45, and the like are set so as to positively allow a slight inclination of the ferrule terminal 18 with the collar portion 17 when the ferrule terminal 18 is inserted.
The abutting portion 44 abuts against the tip 17a of the collar portion 17 when inserted into the ferrule terminal 18, thereby preventing further insertion. Further, the abutting portion 44 is set so as to leave a gap between the front end of the terminal portion 18a of the ferrule terminal 18 and the intermediate base 46, as shown in fig. 5, so that the front end of the terminal portion 18a does not collide with the intermediate base 46 when the ferrule terminal 18 is inserted. The step d is set so that the base end 17b of the collar portion 17 is disposed between the first surface 41 and the second surface 42 when the tapered surface 19 of the collar portion 17 abuts against the abutment portion 44. It is assumed that the length of the collar portion 17 is 6.0mm, the length of the ferrule terminal 18 is 8.0mm, and the total length is 14.0mm, and the step d is set in the range of 1.5 to 2.0 mm.
When a tool such as a driver is inserted into the tool insertion hole 25, the plate spring 34 is pressed by the tip of the tool and elastically deformed, and the ferrule terminal 18 can be pulled out when the spring force of the plate spring 34 is released.
Action
Next, the main operation of the embodiment will be described.
When inserting the ferrule terminal 18 into the wire insertion hole 24 of the housing 15, the operator may erroneously believe that the insertion is completed due to the tactile sensation when the ferrule terminal 18 engages with the plate spring 34 inside the housing 15, and the insertion amount may be insufficient. Even if the amount of insertion is insufficient, it is difficult to recognize the insertion at a glance.
Therefore, the first surface 41 and the second surface 42 having the step d are formed on the housing 15. The abutting portion 44 of the wire insertion hole 24 abuts against the tapered surface 19 of the collar portion 17 when the ferrule terminal 18 is inserted, and prevents further insertion. The height of the step d is set so that the root end 17b of the collar 17 is disposed between the first surface 41 and the second surface 42 in this state.
Fig. 6 is a perspective view (after insertion) showing a step between the first surface and the second surface.
When the ferrule terminal 18 is inserted into the wire insertion hole 24 and the tip 17a of the collar portion 17 abuts against the abutting portion 44, the root end 17b of the collar portion 17 is disposed between the first surface 41 and the second surface 42. Thus, whether the insertion operation is completed correctly can be visually recognized. That is, when the base end 17b of the retainer 17 is located between the first surface 41 and the second surface 42, the completion of the insertion is indicated, and when the base end 17b of the retainer 17 is located outside the first surface 41, the insufficient insertion amount is indicated. Thus, it is possible to easily recognize whether or not the insertion operation is correctly completed with a simple configuration without newly adding a component.
When the ferrule terminal 18 is inserted into the wire insertion hole 24, the plate spring 34 is pressed by the ferrule terminal 18 and elastically deformed. When the ferrule terminal 18 is inserted between the tip end of the plate spring 34 and the pressing surface 33, the ferrule terminal 18 is pressed against the pressing surface 33 by the elastic force of the plate spring 34, and displacement in the withdrawal direction is suppressed. Thus, looseness and falling off of the ferrule terminal 18 can be suppressed.
On the other hand, when a tool is inserted into the tool insertion hole 25, the plate spring 34 is pressed by the tool and elastically deformed, and the ferrule terminal 18 is released from the elastic force of the plate spring 34. Thus, the ferrule terminal 18 can be easily extracted by using a tool.
In the wire insertion hole 24, the large diameter portion 43 is larger than the collar portion 17, and the side of the inner peripheral surface in the direction opposite to the pressing direction toward the pressing surface 33 is inclined by an angle θ in the direction opposite to the pressing direction toward the second surface 42. Further, the taper angle of the abutment portion 44 is made different from the angle of the tapered surface 19 so that the abutment portion 44 does not come into surface contact with the tapered surface 19 of the collar portion 17. Further, the small diameter portion 45 is larger than the ferrule terminal 18. Thus, the ferrule terminal 18 with the ferrule portion 17 is fitted into the wire insertion hole 24 with a certain margin. Therefore, when the ferrule terminal 18 is inserted, a slight inclination of the ferrule terminal 18 with the collar portion 17 is allowed, and the ferrule terminal 18 can be reliably brought into contact with the pressing surface 33, so that the quality of electrical connection is stabilized.
Modifications of the examples
In the above embodiment, the structure in which the abutting portion 44 is a tapered surface has been described, but the present invention is not limited to this. Since the ferrule terminal 18 is brought into contact with the tip of the collar 17 at the time of insertion to prevent further insertion, a simple step may be used.
In the above embodiment, the structure in which the taper angle of the abutting portion 44 with respect to the depth direction is larger than the angle of the tapered surface 19 with respect to the depth direction has been described, but the present invention is not limited to this. The contact portion 44 may have a taper angle smaller than the angle of the tapered surface 19 with respect to the depth direction. This is to easily allow inclination of the ferrule terminal 18 with the ferrule portion 17. However, if the inclination of the ferrule terminal 18 with the ferrule portion 17 can be allowed by the margin of the ferrule portion 17 with respect to the large diameter portion 43 and/or the margin of the ferrule terminal 18 with respect to the small diameter portion 45, the taper angle of the contact portion 44 with respect to the depth direction may be matched with the angle of the tapered surface 19.
In the above embodiment, the c-contact relay in which the a-contact terminal and the b-contact terminal are combined has been described, but the present invention is not limited thereto, and can be applied to a relay of the a-contact and a relay of the b-contact. Further, although the description has been given of the relay having the 4-pole contact, the present invention is not limited thereto, and can be applied to a 1-pole, 2-pole, or 3-pole relay. Further, the present invention is not limited to the relay, and can be applied to a timer.
In the above-described embodiment, the terminal socket for connecting the relay, the timer, and the like to the external circuit has been described, but the present invention is not limited thereto. The present invention can be applied to any other electronic device and accessory device as long as the terminal structure is a spring-type terminal structure capable of holding the ferrule terminal 18 with the ferrule portion 17 inserted into the housing 15.
While the above description has been made with reference to a limited number of embodiments, it will be apparent to those skilled in the art that modifications to the above described embodiments will be apparent that the invention is not limited to such embodiments.
