Electrically connected. That is, in conjunction with the insertion operation of the male terminal, an operation of twisting the cylindrical spring member occurs, and the contact pressure between the male terminal and the female terminal can be obtained. Therefore, the contact pressure between the male terminal and the female terminal can be reduced to zero or small until the male terminal insertion operation starts and immediately before the completion, and the contact pressure can be increased when the insertion operation is completed. Thereby, while making a male terminal and a female terminal contact with a high contact pressure, the insertion resistance at the time of inserting a male terminal in a female terminal can be reduced, and the connector which can improve the working efficiency of insertion is obtained.

The slot formed in the housing extends in the length direction of the female terminal,
As the male terminal is inserted into the female terminal, the projecting portion slides along each slot and the spring member is twisted.

  According to the third aspect, the protrusion engages with the groove formed in the spring member and the groove formed in the housing. The slot formed in the spring member has an inclined portion extending in a direction inclined with respect to the length direction of the female terminal, and the slot formed in the housing extends in the length direction of the female terminal. . For this reason, as the male terminal is inserted into the female terminal, the protrusion slides along each slot and the spring member is twisted. By making the slot formed in the housing and the slot formed in the spring member cooperate, the spring member can be easily and reliably twisted.

According to a fourth invention, in the first invention,

  The male terminal 2 is held in a female housing (not shown), and the female terminal 3 is held in a male housing (not shown). The male terminal 2 is inserted into the female terminal 3 by inserting the male housing into the female housing. The male housing and the female housing are provided with a lock mechanism (not shown) for locking the male housing and the female housing in the inserted state.

  In the following description, in the female terminal 3, the side on which the male terminal 2 is inserted is referred to as the “front side” of the female terminal 3, and the side opposite to the side on which the male terminal 2 is inserted is referred to as the “rear side” of the female terminal 3. . In the male terminal 2, the side inserted into the female terminal 3 is referred to as the “front side” of the male terminal 2, and the side opposite to the side inserted into the female terminal 3 is referred to as the “rear side” of the male terminal 2.

  The male terminal 2 is a conductive member having a columnar inserted portion 21 to be inserted into the female terminal 3. A pair of protrusions 22 are formed near the rear end of the male terminal 2 of the inserted portion 21. The protrusion 22 corresponds to the first guide portion in the claims. One protrusion 22 is formed at each of both ends of the diameter of the section to be inserted 21 in the direction perpendicular to the axis. The protrusion 22 is formed in a cylindrical shape. The length of the diameter of the protrusion 22 is set to be smaller than the width of a slot 311 of the spring member 31 described later. Although the material of the male terminal 2 is not specifically limited, For example, it can be set as a copper alloy.

  The male terminal 2 has a pair of conductor barrels 23 behind the inserted portion 21. That is, the conductor barrel 23 is connected to the rear end portion of the inserted portion 21. The conductor barrel 23 is crimped by crimping to a conductor (not shown) exposed at the end of the covered electric wire, and is electrically connected to the conductor.

  The spring member 31 is a cylindrical elastic member and has a twisted portion 313 that can be twisted in the circumferential direction. By twisting the twisted portion 313, the central portion of the spring member 31 is bundled. The spring member 31 elastically presses the peripheral surface of the inserted portion 21 of the male terminal 2 at the constricted central portion. In the illustrated example, the twisted portion 313 has a plurality of slits 312 extending in the axial direction in the circumferential direction. By forming the plurality of slits 312, the twisted portion 313 can be twisted in the circumferential direction. The material of the spring member 31 is not particularly limited, but may be a copper alloy, for example.

  The spring member 31 has a cylindrical body 314 behind the twisted portion 313. That is, the cylindrical body 314 is connected to the rear end portion of the twisted portion 313. The cylindrical body 314 has a slot 311.

  The slot 311 will be described more specifically. The slot 311 is a slot that engages with the protrusion 22. The slot 311 has an inclined portion 316 extending in a direction inclined with respect to the length direction of the female terminal 2 (see FIG. 4). FIG. 4 is a diagram showing a state in which the protrusion 22 of the male terminal 2 engages with the slot 311 and the slot 321 of the female terminal 3, and (a) is before the insertion of the male terminal 2 into the female terminal 3 is completed. FIG. 6B is a diagram showing a state after the insertion of the male terminal 2 into the female terminal 3 is completed. As the male terminal 2 is inserted into the female terminal 3, the protrusion 22 slides along the inclined portion 316 as shown in FIG. Further, the groove 311 further has a protrusion holding part 317 for holding the protrusion part 22. The protrusion holding portion 317 extends from the end position of the inclined portion 316 in the insertion direction. When the protrusion 22 reaches the protrusion holding portion 317, the position of the protrusion 22 is held by the protrusion holding portion 317.

  The housing 32 accommodates the spring member 31 and fixes only the rear end 315 of the spring member 31 inside. The inner diameter of the housing 32 is slightly larger than the outer diameter of the spring member 31 so that the spring member 31 can be twisted inside the housing 32. The method for fixing the rear end of the spring member 31 in the housing 32 is not particularly limited, and can be fixed by, for example, an adhesive. Although the material of the housing | casing 32 is not specifically limited, For example, it can be set as a copper alloy.

  The housing 32 has a slot 321 on the front side. The slot 321 is a slot formed linearly along the length direction of the housing 32. The width of the slot 321 and the width of the slot 311 of the spring member 31 are set to be substantially the same. That is, as shown in FIG. 4, the widths of the slot 321 and the slot 311 are set to be larger than the length of the diameter of the protrusion 22. As shown in FIG. 4A, the positions of the opening of the slot 321 and the opening of the slot 311 are substantially the same before the male terminal 2 is inserted into the female terminal 3. Yes. As shown in FIG. 4A, the protrusion 22 is aligned with the slot 321 of the housing 32 and the slot 311 of the spring member 31, and the male terminal 2 is inserted into the female terminal 3, so that FIG. As shown, the spring member 31 is twisted, and the central portion of the spring member 31 is bundled. The spring member 31 presses the male terminal 2 at the central portion to be bundled. Thereby, the male terminal 2 and the female terminal 3 are electrically connected.

Next, a procedure for connecting the male terminal 2 to the female terminal 3 will be described.
First, as shown in FIG. 1C, the user inserts the front end of the male terminal 2 into the female terminal 3. At this time, as shown in FIG. 4A, the protrusion 22 of the male terminal 2 is aligned with the opening of the slot 321 and the opening of the slot 311.

  Next, the male terminal 2 is inserted deeply into the female terminal 3 while pushing the protrusion 22 of the male terminal 2 into the groove hole 321 and the groove hole 311. As the male terminal 2 is inserted into the female terminal 3, the protrusion 22 slides along the inclined portion 316 and the groove 321 of the slot 311, and the central portion of the spring member 31 gradually increases. The inner diameter of the constricted portion is larger than the outer diameter of the inserted portion 21 of the male terminal 2 until just before the protruding portion 22 reaches the protruding holding portion 317. Therefore, the male terminal 2 can be easily inserted into the female terminal 3.

  When the protrusion 22 reaches the deepest part of the protrusion holding part 317, the insertion operation is finished (see FIG. 4B). When the protruding portion 22 reaches the protruding holding portion 317, the inner diameter of the constricted portion of the spring member 31 becomes equal to or smaller than the outer diameter of the inserted portion 21 of the male terminal 2. Therefore, the peripheral surface of the male terminal 2 is elastically pressed by the constricted portion of the spring member 31, the male terminal 2 is firmly fixed to the female terminal 3, and the male terminal 2 and the female terminal 3 are electrically connected. Is done.

When the protrusion 22 reaches the protrusion holding part 317, the position of the protrusion 22 is held by the protrusion holding part 317. The spring member 31 attempts to restore torsion to its original state due to its elasticity, but a force for restoring torsion (torsion restoring force) is generated in the circumferential direction of the spring member 31. Since the protrusion holding portion 317 and the groove hole 321 extend in the length direction of the spring member 31, the torsional restoring force acts on the side wall surface of the protrusion holding portion 317 and the side wall surface of the groove hole 321 at right angles. Therefore, the twist of the spring member 31 is not restored, and the position of the protrusion 22 is held by the protrusion holding part 317.
The above is the procedure for connecting the male terminal 2 to the female terminal 3.

  As described above, the male terminal 2 is held in the female housing (not shown), and the female terminal 3 is held in the male housing (not shown). The male housing and the female housing are provided with a locking mechanism for locking the male housing and the female housing in the inserted state. Therefore, restoring the twist of the spring member 31 is also prevented by setting the lock mechanism to the locked state.

  As shown in FIG. 5, a notch 318 may be formed on the side wall surface of the protrusion holding part 317, and the protrusion 22 may be fitted into the notch 318. FIG. 5 is a view showing a modified example of the protrusion holding portion 317. With this configuration, the protrusion 22 can be more reliably held by the notch 318. In addition, illustration of the slot 321 is abbreviate | omitted in FIG.

  As described above, according to the first embodiment, the spring member 31 is twisted and bundled by inserting the male terminal 2 into the female terminal 3 by aligning the protrusion 22 with the slot 311 and the slot 321. The male terminal 2 and the female terminal 3 are electrically connected at the center. That is, in conjunction with the insertion operation of the male terminal 2, an operation of twisting the spring member 31 occurs, and the contact pressure between the male terminal 2 and the female terminal 3 can be obtained. Therefore, the contact pressure between the male terminal 2 and the female terminal 3 can be made zero or small until the male terminal 2 is inserted and immediately completed, and the contact pressure can be increased when the insertion operation is completed. Thereby, while the male terminal 2 and the female terminal 3 are made to contact with a high contact pressure, the insertion resistance at the time of inserting the male terminal 2 in the female terminal 3 can be reduced, and the connector 1 which can improve the work efficiency of insertion. can get.
