Disclosure of Invention
Problems to be solved by the invention
Since the elastic contact portion must be surely in elastic contact with the circuit board, the elastic contact portion enters the board housing space in a state where the circuit board is not inserted into the board housing space. On the other hand, at the front end portion of the terminal accommodating chamber, a gap is secured between the inner wall surface of the terminal accommodating chamber and the outer surface of the terminal fitting as a means for smoothly inserting the terminal fitting into the terminal accommodating chamber.
Therefore, when the terminal component is disposed above the board housing space, the terminal component is displaced downward within the range of the gap by its own weight, and as a result, the amount of entry of the elastic contact portion into the board housing space becomes large. If the amount of insertion of the elastic contact portion is increased, the insertion end portion of the circuit board may be caught by the elastic contact portion that has entered largely when the circuit board is inserted into the board housing space, thereby causing an obstacle to the insertion operation.
The present invention has been made in view of the above circumstances, and an object thereof is to smoothly insert a circuit board into a housing.

Detailed Description
< example 1>
Hereinafter, embodiment 1 embodying the present invention will be described with reference to fig. 1 to 4. In the following description, the right direction in fig. 1 to 3 is defined as the front direction with respect to the front-rear direction. The directions shown in fig. 1 to 4 are defined as up and down as they are with respect to the up-down direction.
The connector a of the present embodiment includes a housing 10 made of synthetic resin and a plurality of terminal fittings 30, and the plurality of terminal fittings 30 are housed in the housing 10. The housing 10 is configured by assembling a housing main body 11 and a front holder 12. A terminal housing chamber 13 is formed in the housing body 11, and the terminal housing chamber 13 is formed to penetrate the housing body 11 in the front-rear direction. The terminal accommodating chambers 13 are formed such that the vertically arranged terminal accommodating chambers 13 are opposed to each other and a plurality of pairs of the terminal accommodating chambers 13 are arranged in parallel at a predetermined pitch in the left-right direction.
A lance 14 is formed in the terminal accommodating chamber 13 on the upper stage side, and the lance 14 extends forward in a cantilever manner along the upper wall surface of the terminal accommodating chamber 13. The lance 14 is formed with a retaining projection 15. The lance 14 prevents the terminal fitting 30 from coming off by locking the coming-off preventing projection 15 to the terminal fitting 30 inserted into the terminal accommodating chamber 13. In the process of inserting the terminal fitting 30 into the terminal accommodating chamber 13, the lance 14 interferes with the terminal fitting 30 and is elastically deformed upward. The lower side terminal housing chamber 13 is also formed with a lance 14 vertically symmetrical to the lance 14 on the upper side.
Further, a slit-shaped substrate housing space 16 is formed between the upper stage side terminal housing chamber 13 and the lower stage side terminal housing chamber 13, and the substrate housing space 16 extends in a horizontally elongated manner. The substrate storage space 16 is open to the front end surface of the housing 10, and communicates with the front end portions of the upper and lower terminal storage chambers 13. The connection edge portion 40E of the circuit board 40 is inserted into the board housing space 16 from the front of the housing 10. The circuit board 40 is mounted on the substrate holder 41. A plurality of contact portions (not shown) are arranged in the left-right direction in the connection edge portion 40E.
The front holder 12 is assembled to the front end portion of the housing main body 11. The front holder 12 has a pair of front wall portions 17 that are vertically symmetrical, and the front wall portions 17 close the openings at the front ends of the upper and lower terminal receiving chambers 13, respectively. A substrate insertion opening 18 is opened between the upper front wall 17 and the lower front wall 17, and the substrate insertion opening 18 is in the form of a horizontally long slit that communicates with the front end of the substrate accommodating space 16. The connection edge 40E of the circuit board 40 penetrates the board insertion port 18. The front holder 12 has a peripheral wall portion 19 that surrounds the outer periphery of the housing main body 11. The front end of the peripheral wall 19 continues from the front wall 17. The peripheral wall portion 19 is formed with a deflection space 20, and the deflection space 20 is for allowing the lance 14 to be elastically deformed by interference with the terminal fitting 30.
The front wall 17 is formed with a plurality of receiving portions 21. The receiving portion 21 penetrates the front wall portion 17 in the front-rear direction (direction substantially parallel to the direction in which the terminal fitting 30 is inserted into the terminal accommodating chamber 13). The front end of the receiving portion 21 opens to the front end surface of the housing 10 (front holder 12). The opening shape of the receiving portion 21 at the rear surface (the surface opposite to the terminal accommodating chamber 13) of the front wall portion 17 is circular.
The terminal fitting 30 is formed in a shape elongated in the front-rear direction as a whole. An electric wire 35 is connected to a rear end of the terminal fitting 30. A waterproof rubber plug 36 is provided between the inner periphery of the rear end portion of the terminal accommodating chamber 13 and the outer periphery of the electric wire 35. A terminal body 31 having a substantially square tubular shape is formed at the distal end of the terminal fitting 30. A stepped locking portion 32 is formed in a region of the outer peripheral surface of the terminal body 31 on the opposite side of the region facing the board housing space 16.
During the insertion of the terminal fitting 30 into the terminal accommodating chamber 13, the outer surface of the terminal main body portion 31 interferes with the retaining projection 15, so that the lance 14 is elastically displaced in such a manner as to retreat from the terminal accommodating chamber 13. When the terminal fitting 30 reaches the normal insertion position, the distal end of the terminal body 31 abuts against the front wall 17, and the terminal fitting 30 is restricted from further movement. When the terminal fitting 30 is restricted from further movement, the retaining portion 32 passes through the retaining projection 15 at substantially the same time, and therefore the lance 14 is elastically restored, so that the retaining projection 15 can be retained to the retaining portion 32. The terminal fitting 30 is prevented from falling off by this locking action.
In addition, at the front end portion of the terminal accommodating chamber 13, since the terminal body portion 31 can be inserted without being caught by the terminal accommodating chamber 13, a gap in the vertical direction is secured between the inner surface of the terminal accommodating chamber 13 and the outer surface of the terminal body portion 31. The terminal body 31 is displaced in the vertical direction relative to the housing 10 (the terminal accommodating chamber 13) by the gap, although only a little. The direction of the relative displacement is a direction in which the terminal body 31 approaches or separates from the board housing space 16.
An elastic contact portion 33 is formed in a region of the outer peripheral surface of the terminal body portion 31 facing the substrate accommodating space 16, and the elastic contact portion 33 protrudes toward the substrate accommodating space 16. The elastic contact portion 33 elastically contacts the contact portion of the circuit board 40 inserted into the board housing space 16. In a state where the circuit board 40 is not inserted into the substrate accommodating space 16, a part of the elastic contact portion 33 enters into the substrate accommodating space 16. With the gap between the terminal accommodating chamber 13 and the terminal fitting 30 as described above, the amount of entry of the elastic contact portion 33 into the substrate accommodating space 16 increases or decreases when the terminal body portion 31 is relatively displaced toward the substrate accommodating space 16 side with respect to the terminal accommodating chamber 13.
When the amount of insertion of the elastic contact portion 33 into the board housing space 16 increases, the connection end edge portion 40E of the board 40 may contact the elastic contact portion 33 during the insertion of the board 40 into the board housing space 16, thereby hindering the insertion operation. In this embodiment, the receiving portion 21 and the fitting portion 34 described later are provided as measures against this.
The fitting portion 34 is disposed on the distal end surface of the terminal body 31. That is, in a state where the terminal fitting 30 is normally inserted into the terminal accommodating chamber 13, the fitting portion 34 is disposed at a position close to and opposed to the receiving portion 21 of the front wall portion 17. The fitting portion 34 is formed in a shape in which a part of a wall portion constituting the terminal body portion 31 is struck forward (in a direction approaching the front wall portion 17) to protrude. The fitting portion 34 has a substantially spherical shape, and the maximum outer diameter of the fitting portion 34 is set to be slightly larger than the inner diameter of the receiving portion 21.
Next, the operation of the present embodiment will be described. In a state where the terminal component 30 is normally inserted into the terminal accommodating chamber 13, the terminal body 31 of the terminal component 30 inserted into the terminal accommodating chamber 13 on the upper stage side is displaced toward the board accommodating space 16 side by its own weight. However, at the front end of the terminal body 31, the fitting portion 34 is fitted into the receiving portion 21, and the fitting portion 34 is locked from above to the opening edge of the receiving portion 21 on the rear surface (the surface facing the terminal accommodating chamber 13) of the front wall 17, so that the downward displacement of the terminal body 31 is restricted. Thereby, the amount of entry of the elastic contact portion 33 into the substrate accommodating space 16 is kept within the appropriate size range.
After the terminal component 30 is inserted into the terminal accommodating chamber 13, the connecting end portion 40E of the circuit board 40 is inserted into the board insertion port 18 opened in the front end surface of the housing 10 and accommodated in the board accommodating space 16. At this time, since the amount of the elastic contact portion 33 entering the board housing space 16 is maintained within the appropriate size range, the connection end edge portion 40E does not contact the elastic contact portion 33 or get caught by the elastic contact portion 33. When the circuit board 40 is smoothly inserted into the board housing space 16, the connection end edge portion 40E is inserted between the upper stage side elastic contact portion 33 and the lower stage side elastic contact portion 33, and the upper and lower elastic contact portions 33 are elastically deformed. By the elastic restoring force of the two elastic contact portions 33, the elastic contact portions 33 and the contact portions of the circuit board 40 are connected with an appropriate contact pressure.
The connector a of the present embodiment includes a housing 10 and a terminal fitting 30, a terminal housing chamber 13 is formed in the housing 10, and the terminal fitting 30 is inserted into the terminal housing chamber 13 from the rear of the housing 10. A board housing space 16 is formed in the housing 10, the board housing space 16 is opened in a slit shape through a board insertion port 18 in the front surface of the housing 10, an elastic contact portion 33 is formed in the terminal component 30, and the elastic contact portion 33 elastically contacts a connection end edge portion 40E of the circuit board 40 inserted into the board housing space 16. Further, a front wall portion 17 is formed at a front end portion of the terminal accommodating chamber 13, and the front wall portion 17 abuts against the terminal fitting 30 inserted into the terminal accommodating chamber 13 to restrict further movement of the terminal fitting 30.
The front wall 17 is formed with a receiving portion 21. A fitting portion 34 is formed on the distal end surface of the terminal component 30, and the fitting portion 34 is fitted to the receiving portion 21 in a state where relative displacement toward the substrate accommodating space 16 side is restricted. According to this structure, since the receiving portion 21 is fitted with the fitting portion 34 so as to restrict the elastic contact portion 33 from largely entering the substrate accommodating space 16, the circuit board 40 does not touch the elastic contact portion 33 in the process of its insertion into the substrate accommodating space 16. This allows the circuit board 40 to be smoothly inserted into the housing 10.
The receiving portion 21 penetrates the front wall portion 17 and opens to the front end surface of the housing 10. The fitting portion 34 is fitted into the receiving portion 21 in a protruding manner. According to this configuration, the probe P is inserted from the front of the housing 10 and brought into contact with the fitting portion 34, so that conduction inspection can be performed.
