Japanese Patent No. 4883215

  In the connection terminal 30 of Patent Document 1, since the extending portion 34 is composed of a plurality of first, second, and third extending portions 34a, 34b, and 34c, stress concentration hardly occurs. However, when the movable contact portion 36 is pushed in, the movable contact portion 36 moves toward the position restricting receiving portion 17 as shown in FIGS. 24 (a) and 24 (b). Such movement is called so-called wiping. In general, wiping is used for the purpose of scraping off an oxide film generated on the surfaces of the connection terminal 30 and the counterpart substrate to improve contact reliability. However, when the amount of wiping increases, the amount of contact displacement increases when the connection terminal 30 and the counterpart substrate are coupled, and contact failure is likely to occur unless the area of the contact surface of the counterpart substrate is increased.

  Then, an object of this invention is to provide the connector which can control the amount of wiping in order to suppress a contact failure.

  The connector which concerns on 1 aspect of this invention is provided with a housing and a connection terminal. The housing has a contact hole and a latch receiving portion adjacent to the contact hole. The connection terminal is accommodated in the housing. Here, the connection terminal includes a fixed portion, an extending portion, a movable contact portion, a locking portion, and a connecting rigid body portion. The fixed part is fixed to the housing. One end of the extended portion is curved from the fixed portion and has elasticity. The movable contact portion protrudes from the outside of the contact hole of the housing so as to be pressed. Further, the movable contact portion has a guide portion extending along the pressing direction, and the end surface of the latch receiving portion facing the contact hole and the guide portion are pressed from the outside of the contact hole with the maximum displacement amount. Touch before touching. The locking portion is connected to the other end of the extending portion, and is locked to the locking receiving portion of the housing in a state where the movable contact portion is not pressed. The connecting rigid body portion connects the locking portion and the movable contact portion.

  According to the above configuration, the guide portion of the movable contact portion comes into contact with the end surface of the latch receiving portion facing the contact hole of the housing before the movable contact portion is pressed into the housing with the maximum amount of displacement.

  For example, the guide portion may be formed with a predetermined slope on the side away from the latch receiving portion from the base portion toward the tip, not parallel to the end face of the latch receiving portion. In this case, there may be a predetermined gap between the guide portion and the end surface of the latch receiving portion of the housing in a state where the movable contact portion is not pressed. When the movable contact portion is pushed into the housing by a predetermined distance, the guide portion can come into contact with the end surface of the latch receiving portion of the housing due to the force of pressing from the extending portion toward the latch receiving portion. Thereafter, the movable contact portion is pushed into the housing in a state where the inclined guide portion and the end face of the latch receiving portion are in contact with each other. Therefore, it is possible to control the amount of movement of the movable contact portion, that is, the amount of wiping, in accordance with the inclination angle of the guide portion and the maximum displacement amount. Therefore, contact failure between the movable contact portion and the counterpart substrate due to wiping of the movable contact portion can be suppressed. For example, to reduce the wiping amount of the movable contact portion, the inclination angle of the guide portion is reduced. Conversely, to increase the wiping amount of the movable contact portion, the inclination angle of the guide portion is increased.

  Further, the end surface of the guide portion on the side of the latch receiving portion may extend along the vertical direction in parallel to the end surface of the latch receiving portion. In this case, the guide portion and the end face of the latch receiving portion of the housing are in contact with each other when the movable contact portion is not pressed. Even when the movable contact portion is pushed into the housing, the contact state is maintained. Therefore, it is possible to control so as to suppress the wiping amount as described above.

  Further, in a state where the movable contact portion protrudes from the housing at the maximum, the extending portion is elastically deformed and stored in the housing. Therefore, the movable contact portion receives a force of pushing from the extending portion in a direction protruding from the contact hole of the housing. And when a movable contact part is pushed in by the other party board | substrate, a movable contact part receives the force further pushed out from an extension part. Therefore, the contact force between the movable contact portion and the counterpart substrate can be increased.

  Moreover, the stroke amount of the movable contact portion in the pushing direction can be adjusted by adjusting the length of the movable contact portion protruding from the housing and the elastic force of the extending portion.

  Preferably, after the guide portion and the end surface of the latch receiving portion are in contact, the movable contact portion is pushed in while the guide portion is in contact with the end surface of the latch receiving portion.

  The movable contact portion is pushed into the housing in a state where the inclined guide portion and the end surface of the latch receiving portion are in contact with each other. Therefore, it is possible to control the amount of movement of the movable contact portion, that is, the amount of wiping, in accordance with the inclination angle of the guide portion and the maximum displacement amount.

  Preferably, the contact area between the guide portion and the end face of the latch receiving portion is linear. Therefore, the end surface of the guide portion on the side of the latch receiving portion and the end surface of the latch receiving portion are in close contact with each other. Since the movable contact portion is pushed into the housing in such a close contact state, the wiping amount can be controlled as described above.

  Preferably, the end face of the latch receiving portion of the housing and the guide portion of the movable contact portion contact each other until the displacement of the movable contact portion in the pushing direction reaches 1/5 of the maximum displacement amount.

  When the movable contact portion is pushed into the housing, the end surface of the latch receiving portion of the housing and the guide portion of the movable contact portion contact each other until reaching 1/5 of the maximum displacement. In this case, the inclination angle of the guide portion with respect to the end surface of the latch receiving portion is set to be small, and immediately after the movable contact portion is pushed into the housing, the guide of the end surface of the latch receiving portion of the housing and the guide of the movable contact portion is obtained. The part comes into contact. Thereby, the amount of wiping of a movable contact part can be suppressed.

  Preferably, the end surface of the latch receiving portion of the housing and the guide portion of the movable contact portion contact each other until the displacement of the movable contact portion in the pushing direction reaches 1/10 of the maximum displacement amount.

  When the movable contact portion is pushed into the housing, the end surface of the latch receiving portion of the housing and the guide portion of the movable contact portion contact each other until reaching 1/10 of the maximum displacement. The inclination angle of the guide portion with respect to the end surface of the lock receiving portion is set to be smaller than that in the case where the end surface of the lock receiving portion and the guide portion contact each other until reaching 1/5 of the maximum displacement. Therefore, the amount of wiping of the movable contact portion can be further suppressed.

  Preferably, the end surface of the latch receiving portion of the housing and the guide portion of the movable contact portion are arranged in contact with each other in a state where the movable contact portion is not pressed. Note that “arranged so as to be in contact” does not necessarily mean that they are in contact, and a gap corresponding to a dimensional tolerance between components is allowed. Specifically, the gap corresponding to the dimensional tolerance is 0.1 mm or less, and when the movable contact portion is further pushed into the dimensional tolerance, the end face of the latch receiving portion and the guide portion are in contact with each other. Means that it is configured.

  Since the end surface of the latch receiving portion and the guide portion are in contact with each other and the movable contact portion is pushed into the housing in this state, the amount of wiping can be suppressed.

  Preferably, the locking portion extends to the opposite side of the fixed portion with respect to the connecting rigid body portion provided on the free end side of the extending portion, and the movable contact portion is not pressed in the housing. Locked to the lock receiving portion.

  Since the locking part extends along the extending direction of the extending part, the elasticity of the extending part can be used efficiently. Moreover, since the latching | locking part is located in the front-end | tip of an extending part, it can latch the latching | locking part to a latching receiving part stably by receiving the elastic force from an extending part.

  Preferably, the strength of the connecting rigid body portion is stronger than the strength of the extending portion.

  Since the strength of the connecting rigid body portion is stronger than the strength of the extending portion, conversely, the elasticity of the connecting rigid body portion is smaller than the elasticity of the extending portion. Although the movable contact portion is connected to the connecting rigid body portion, the movable contact portion is stably fixed to the connecting rigid body portion because the elasticity of the connecting rigid body portion is small. Therefore, wiping of the movable contact portion due to the elasticity of the connecting rigid body portion can be suppressed.

  Preferably, the width of the connecting rigid body portion is wider than the width of the extending portion.

  Since the width of the connecting rigid body portion is wider than the width of the extending portion, the strength of the connecting rigid body portion can be made stronger than the strength of the extending portion. Therefore, wiping of the movable contact portion due to the elasticity of the connecting rigid body portion can be suppressed. However, since the elasticity of the extension portion is lost if the width of the connection rigid body portion is too large, the width of the connection rigid body portion is adjusted to such an extent that the elasticity of the extension portion is not lost.

  Preferably, the movable contact portion further includes a contact portion provided at a tip end of the guide portion in a direction protruding outward from the contact hole of the housing.

  The contact portion is formed to be small in the movable contact portion, and the contact portion and the counterpart substrate come into contact with each other, so that the contact area between the counterpart substrate and the contact portion is small. Here, misalignment and mounting misalignment may occur between the connection terminal and the housing, between the connector and the counterpart substrate, and the like. However, since the contact area between the mating substrate and the contact portion is small and the displacement of the contact portion within the mating substrate is small, contact between the contact portion and the mating substrate is possible even when there is a displacement in the XY direction. Is maintained. Therefore, the influence of the contact failure by the shift | offset | difference in the fitting process of a connector etc. and a mounting process can be suppressed.

  Preferably, the movable contact portion further includes a facing side portion that is opposed to the guide portion and whose distance from the guide portion decreases toward the tip.

  The movable contact part has a guide part and an opposing side part, and has a shape in which the distance between the guide part and the opposing side part becomes narrower toward the tip. Therefore, it is easy to insert the movable contact portion from the contact hole of the housing.

  Preferably, the opposing side portion has a curved shape.

  Since the opposing side portion has a curved shape, the stress in the cross section in the direction intersecting the pushing direction of the movable contact portion can be made substantially uniform in any cross section. Therefore, the strength of the movable contact portion can be increased.

  Preferably, the extending part is composed of a plurality of extending parts that are curved to be spaced apart from each other.

  Since the extension part consists of a plurality of extension parts, the elastic force of the extension part can be increased. Therefore, the locking portion can be stably locked to the locking receiving portion of the housing, and the contact force between the movable contact portion and the counterpart substrate can be ensured.

  Preferably, the extending portion includes a first bending portion and a second bending portion in directions in which opening directions are different. Between the first bending portion and the second bending portion, a plurality of extending portions are connected by a restricting connecting portion.

  The restriction connecting portion connects a plurality of extending portions between the first bending portion and the second bending portion. Therefore, a plurality of extending portions can be moved in conjunction with each other. Therefore, it becomes easy to control the movement of the plurality of extending portions. When the regulation connecting portion is not provided, for example, it may be difficult to control the movement by moving a plurality of extending portions separately and overlapping each other. In addition, the portion between the first bending portion and the second bending portion is a portion where stress is difficult to be applied. By providing the restriction connecting portion in this portion, stress on the restriction connecting portion can be avoided, and a plurality of portions are provided. It becomes easy to control the movement of the extending portion.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments are specific examples of the present invention and do not limit the technical scope of the present invention.

(1) Configuration of Connector 300 (1-1) Overall Configuration of Connector 300 FIG. 1 is a perspective view of a connector 300 according to an embodiment of the present invention. FIG. 2 is a top view of the connector 300 of FIG. 1 viewed from the protruding direction of the movable contact portion 210. FIG. 3 is a side view of the connector 300, and FIG. 4 is a bottom view of the connector 300 as viewed from the back side opposite to the protruding direction of the movable contact portion 210.

  A connector 300 according to an exemplary embodiment of the present invention includes a housing 100 and a connection terminal 200. As shown in FIG. 1, the housing 100 has, for example, a box shape having a hollow inside and an opening at the bottom so that the connection terminal 200 can be accommodated. The connection terminal 200 is housed in the housing 100 and has a movable contact portion 210 that protrudes from the contact hole 107 of the housing 100 so as to be pressed.

In the connector 300 according to the present embodiment, as an example, the two contact terminals 200a and 200b are used as one set, and the movable contact portion 210 protrudes from four regions. Since the two connection terminals 200 come in contact with the mating substrate 400 (FIG. 13) as a set, contact failure can be suppressed as compared with the case where the one connection terminal 200 contacts the mating substrate 400.

  The connection terminal 200 has a shape along the plate-like surface. Hereinafter, the direction along the plate-like surface is referred to as an X direction, and a direction intersecting with the X direction at approximately 90 ° is referred to as a Y direction. That is, as shown in FIGS. 1 to 4, the connection terminal 200 has a shape along the X direction, with the thickness in the Y direction being sufficiently smaller than the width in the X direction. Further, a direction in which the movable contact portion 210 of the connection terminal 200 protrudes from the housing 100 is defined as a top surface direction or a top surface, and a direction opposite to the top surface is defined as a bottom surface direction or a bottom surface.

(1-2) Housing 100
Next, the structure of the housing 100 will be described below. 5 is a cross-sectional view taken along line AA in FIG. In the cross-sectional view taken along the line A-A in FIG. 5, the two connection terminals 200 are adjacent to each other symmetrically about the second wall 103. Since the configuration is the same, only the left connection terminal 200 and the housing 100 in which the connection terminal 200 is accommodated in FIG. 5 will be described.

  The housing 100 includes a first wall 101 and a second wall 103 having a predetermined thickness as shown in FIG. The first wall 101 is a part of the outer wall of the housing 100. The second wall 103 partitions a space in which each connection terminal 200 adjacent in the X direction is accommodated.

  In the vicinity of the upper surface of the housing 100, an insertion wall 109 and a lock receiving portion 105 are provided. The insertion wall 109 is provided adjacent to the first wall 101. A fixed insertion hole 111 is formed by an opening between the insertion wall 109 and the first wall 101. A distal end of a second fixing portion 201 b of a connection terminal 200 described later is inserted into the fixed insertion hole 111.

  The latch receiving portion 105 has a substantially constant thickness, and extends from the second wall 103 at an angle substantially perpendicular to the second wall 103. A contact hole 107 is formed between the latch receiving portion 105 and the insertion wall 109. From this contact hole 107, the movable contact portion 210 of the connection terminal 200 protrudes so as to be pressed. The upper surface of the insertion wall 109 and the upper surface of the latch receiving portion 105 are flush with each other and constitute a part of the upper surface of the housing 100.

  As shown in FIGS. 1 and 5, a locking hole 112 into which the first fixing portion 201 a of the connection terminal 200 is inserted is provided near the bottom surface of the housing 100.

(1-3) Connection terminal 200
Next, the configuration of the connection terminal 200 will be described below with reference to FIGS. FIG. 6 is a perspective view of the connection terminal 200. 7A is a front view of the connection terminal 200, FIG. 7B is a right side view thereof, FIG. 7C is a left side view thereof, and FIG. 7D is a connection terminal viewed from the movable contact portion 210 side. 2 is a top view of the connection terminal 200 as viewed from the first fixed portion 201a side. FIG. 8A is a front view showing a state in which the extension portion 203 is not pressed, and FIG. 8B is a front view showing a state in which the extension portion 203 is accommodated in the housing 100.

  The connection terminal 200 includes a fixed portion 201, a branch portion 202, an extending portion 203, a locking portion 207, a restricting connecting portion 209, a movable contact portion 210, and a connecting rigid body portion 220. As shown in FIG. 6, the fixed portion 201, the branch portion 202, the extending portion 203, the locking portion 207, the restricting connecting portion 209, the movable contact portion 210, and the connecting rigid body portion 220 are along the plate-like surface in the X direction. It is connected to. That is, the thickness in the Y direction of the connection terminal 200 is sufficiently smaller than the thickness in the X direction.

(A) Fixing part 201
The fixing part 201 includes a first fixing part 201a and a second fixing part 201b. The first fixing portion 201 a is inserted into the locking hole 112 on the bottom surface of the housing 100. Further, as shown in FIG. 5, the bottom portion of the first fixed portion 201a protrudes from the bottom surface of the housing 100 by a predetermined distance so as to be in contact with another substrate. The second fixing portion 201b protrudes upward at a substantially right angle from a predetermined portion of the first fixing portion 201a. The second fixing portion 201 b is inserted along the first wall 101 of the housing 100, and the tip thereof is inserted into the fixed insertion hole 111. As described above, the fixing portion 201 includes the first fixing portion 201 a inserted into the locking hole 112 of the housing 100 and the second fixing portion 201 b inserted into the fixing insertion hole 111 along the first wall 101. 100 is fixed. Thereby, the connection terminal 200 is fixed to the housing 100.

(B) Branching portion 202, extending portion 203
A branching portion 202 projects from the vicinity of the first fixing portion 201a in the second fixing portion 201b to the side opposite to the first wall 101. From the branch part 202, two extending parts 203 having elasticity extend while being branched and curved. The extension part 203 includes a first extension part 203a and a second extension part 203b. The first extending portion 203a and the second extending portion 203b extend in a generally parallel manner with a slit 205 therebetween. The width of the slit 205 is such that the first extending portion 203a and the second extending portion 203b do not contact each other.

  The first extending portion 203a and the second extending portion 203b have a curved portion 208. Specifically, as shown in FIGS. 5 and 6, the first extending portion 203a and the second extending portion 203b have a first bending portion 208a and a second bending portion 208b. The first bending portion 208a and the second bending portion 208b are curved portions of the extending portion 203 excluding a substantially linear portion. The second bending portion 208b is a portion where the extending portion 203 is first bent from the branching portion 202, has an opening on the second fixing portion 201b side, and is bent in a substantially U shape. The first bending portion 208a is a portion where the extending portion 203 is bent next to the second bending portion 208b, and has an opening on the opposite side to the opening direction of the second bending portion 208b. That is, the first bending portion 208a has an opening on the second wall 103 side facing the second fixing portion 201b and is bent in a substantially U shape. By having these two first curved portions 208a and second curved portions 208b, the extending portion 203 has a meandering shape in two places. By having such a curved portion 208, the extension portion 203 has a supple elasticity when pressed from the upper surface direction. And when the movable contact part 210 is pressed, the extension part 203 is compressed by the elasticity. Conversely, when the pressing of the movable contact portion 210 is released, the extending portion 203 pushes the movable contact portion 210 upward due to its elasticity.

  The first bending portion 208a and the second bending portion 208b have the same degree of bending and a width in the X direction. However, the degree of bending and the width in the X direction of the first bending portion 208a and the second bending portion 208b may be different from each other.

  Further, as described above, the extending portion 203 includes a plurality of first extending portions 203a and second extending portions 203b that are spaced apart from each other. Therefore, the elastic force of the extension part 203 can be made stronger than the case of the one extension part 203. Therefore, the locking portion 207 can be stably locked to the locking receiving portion 105 of the housing 100, and the contact force between the movable contact portion 210 and the counterpart substrate 400 can be ensured.

(C) Regulatory connecting portion 209
The regulation connecting portion 209 is a member that connects the first extending portion 203a and the second extending portion 203b. The regulation connecting portion 209 is provided between the first bending portion 208a and the second bending portion 208b. That is, the regulation connecting portion 209 is provided at a substantially linear portion between the first bending portion 208a and the second bending portion 208b. By providing the regulation connecting portion 209, the first extending portion 203a and the second extending portion 203b can be moved in conjunction with each other. Therefore, it becomes easy to control the movement of the first extension portion 203a and the second extension portion 203b. In the case where the restriction connecting portion 209 is not provided, for example, the first extending portion 203a and the second extending portion 203b may move separately and overlap each other, making it difficult to control the movement.

  Further, when the movable contact portion 210 is pushed into the housing 100 from above, stress is applied to the first bending portion 208a and the second bending portion 208b having a large elastic force in the extending portion 203. In other words, the portion between the first bending portion 208a and the second bending portion 208b is a portion where stress is not easily applied. By providing the restricting connecting portion 209 at this portion, stress on the restricting connecting portion 209 can be avoided and the movement of the first extending portion 203a and the second extending portion 203b can be easily controlled.

(D) Locking portion 207
The locking portion 207 is provided at a free end that is the other end of the extending portion 203 that extends from the branch portion 202. As shown in FIG. 5, the locking portion 207 is locked to the locking receiving portion 105 of the housing 100 when the movable contact portion 210 of the connection terminal 200 is not pressed. Specifically, the upper surface of the locking portion 207 is locked to the lower surface of the locking receiving portion 105. The locking portion 207 is disposed on the opposite side of the first bending portion 208 a with respect to the connecting rigid body portion 220 provided on the free end side of the extending portion 203. That is, the extending portion 203 extends from the first curved portion 208a toward the locking receiving portion 105, but the locking portion 207 has a shape extending toward the terminal end direction of the extending portion 203. Yes. Thus, since the latching | locking part 207 extends toward the terminal direction of the extension part 203, the elasticity of the extension part 203 can be utilized efficiently. Moreover, since the latching | locking part 207 is provided in the terminal end of the extension part 203, it receives the elastic force from the extension part 203, and latches the latching part 207 to the latching receiving part 105 stably. Can do. In other words, the locking portion 207 has a shape and arrangement that efficiently uses the elasticity of the extending portion 203.

  Here, FIG. 8A shows a state where the extending portion 203 is not pressed, and FIG. 8B shows a state where the extending portion 203 is accommodated in the housing 100. As shown in FIGS. 8A and 8B, when the extended portion 203 is accommodated in the housing 100 (see FIG. 8B), the extended portion 203 is not pressed and has a free length. The extension part 203 is pushed and shrunk by the pushing length Ld as compared with the case (see FIG. 8A). Therefore, when the connection terminal 200 is accommodated in the housing 100 as shown in FIG. 5, the locking portion 207 presses the locking receiving portion 105 by an elastic force corresponding to the pressed length Ld. Thereby, as described above, the locking portion 207 receives the elastic force from the extending portion 203 and is stably locked to the locking receiving portion 105.

(E) Connection rigid body part 220
The connecting rigid body part 220 continuously connects the locking part 207 and the movable contact part 210. Specifically, the connecting rigid body portion 220 is a portion located near the base 214 of the movable contact portion 210 and on the locking portion 207 side. In other words, the bent portion 221 is provided between the movable contact portion 210 and the second extending portion 203b, and the connecting rigid body portion 220 is provided near the bottom of the opening of the bent portion 221.

  The strength of the connecting rigid body portion 220 is stronger than the strength of the extending portion 203. In other words, the elasticity of the connecting rigid body portion 220 is smaller than the elasticity of the extending portion 203. Although the movable contact portion 210 is connected to the connection rigid body portion 220, the movable contact portion 210 is stably fixed to the connection rigid body portion 220 because the elasticity of the connection rigid body portion 220 is small. In other words, the elastic force of the bent portion 221 is smaller than the elastic force of the first bending portion 208a and the second bending portion 208b of the extending portion 203. Therefore, wiping of the movable contact portion 210 due to the elasticity of the connecting rigid body portion 220 and / or the elasticity of the bent portion 221 can be suppressed.

  Further, as shown in FIG. 10 described later, the width Wc of the narrowest portion of the connecting rigid body portion 220 is wider than the width Wa of the first extending portion 203a and the width Wb of the second extending portion 203b. Therefore, the strength of the connecting rigid body portion 220 is stronger than the strength of the first extending portion 203a and the second extending portion 203b. Therefore, wiping of the movable contact portion 210 due to the elasticity of the connecting rigid body portion 220 can be suppressed.

  However, if the width Wc of the connecting rigid body portion 220 is excessively increased, the elasticity of the extending portion 203 is lost. Therefore, the width Wc of the connecting rigid body portion 220 is adjusted to the extent that the elasticity of the extending portion 203 is not lost.

(F) Movable contact portion 210
The movable contact portion 210 is provided on the free end side of the extending portion 203 that extends from the fixed portion 201. More specifically, the movable contact portion 210 is connected to a locking portion 207 provided at the free end of the extending portion 203 via a connecting rigid body portion 220.

  The movable contact portion 210 is a member that protrudes from the outside of the contact hole 107 of the housing 100 so as to be pressed. The pressing direction of the movable contact portion 210 is generally the vertical direction of the first wall 101 of the housing 100, that is, the direction along the extending direction of the second fixed portion 201b.

  The movable contact portion 210 is provided between the second fixed portion 201 b and the locking portion 207 provided at the end of the free end of the extending portion 203. More specifically, the movable contact portion 210 has an end surface 105 a (see FIG. 5) where the guide portion 211 of the movable contact portion 210 faces the contact hole 107 of the latch receiving portion 105 when the connection terminal 200 is accommodated in the housing 100. 10)). Further, when the movable contact portion 210 is pressed into the housing 100, the movable contact portion 210 receives a force pressed from the extending portion 203 to the locking portion 207 side, that is, the locking receiving portion 105 side. Therefore, as described later, the guide portion 211 of the movable contact portion 210 and the end surface 105a of the latch receiving portion 105 come into contact (see FIG. 11).

  The movable contact part 210 includes a guide part 211, an opposing side part 213, a base part 214, and a contact part 215. The movable contact portion 210 has a plate shape along the X direction. Further, the plate-like surface of the movable contact portion 210 has a generally trapezoidal shape in which the distance between the guide portion 211 and the opposing side portion 213 is narrower toward the distal end side away from the locking portion 207. The guide part 211 faces the latch receiving part 105 side, and extends linearly along the pressing direction. The guide portion 211 is slightly inclined toward the side away from the latch receiving portion 105 from the base portion 214 toward the contact portion 215. When the guide portion 211 has a predetermined inclination, the resistance when the movable contact portion 210 is inserted into the contact hole 107 of the housing 100 is small and easy to insert. The inclination of the guide part 211 will be described later.

  The facing side portion 213 faces the guide portion 211 and faces the fixed insertion hole 111 side opposite to the locking receiving portion 105 and extends linearly. The opposite side portion 213 is inclined from the base portion 214 toward the contact portion 215 toward the locking receiving portion 105. For example, the inclination angle of the opposing side portion 213 with respect to the vertical direction is larger than the inclination angle of the guide portion 211. Due to the inclination of the guide part 211 and the inclination of the opposing side part 213, the distance between the guide part 211 and the opposing side part 213 is narrowed toward the tip of the movable contact part 210. Therefore, the resistance at the time of inserting the movable contact portion 210 into the contact hole 107 is small and easy to insert.

  The base 214 is positioned in the bottom direction of the movable contact portion 210 and serves as the bottom of the movable contact portion 210. A bent portion 221 is formed between the base portion 214 and the vicinity of the terminal end of the second extending portion 203b on the locking portion 207 side.

  The contact portion 215 is narrower in the X direction than the base portion 214, and is provided at the tip of the guide portion 211 in a direction protruding outward from the contact hole 107 of the housing 100. The contact portion 215 is formed to be small in the movable contact portion 210, and the contact portion 215 and the counterpart substrate 400 are in contact with each other, so that the contact area between the counterpart substrate 400 and the contact portion 215 is small. Here, misalignment and mounting misalignment may occur between the connection terminal 200 and the housing 100, between the connector 300 and the mating substrate 400, and the like. However, even if the contact portion 215 moves while the movable contact portion 210 is pushed in, the contact area between the counterpart substrate 400 and the contact portion 215 is small, and the contact portion 215 fits in the counterpart substrate 400. Therefore, the contact between the contact portion 215 and the counterpart substrate 400 is maintained even when there is a deviation in the XY directions. Therefore, the influence of the contact failure by the shift | offset | difference in the fitting process of the connector 300 and a mounting process can be suppressed. Although the contact portion 215 is provided at the tip of the guide portion 211 in the above, it may be provided at another position as long as it is the tip of the movable contact portion 210 in the protruding direction. However, it is preferable to be provided so as to be continuous with the guide portion 211 because the strength of the contact portion 215 can be increased.

  Further, as shown in FIG. 5, in a state where the movable contact portion 210 protrudes from the housing 100 at the maximum, the extending portion 203 is elastically deformed by the pushing length Ld and is accommodated in the housing 100 (see FIG. 5). 8). At this time, the movable contact portion 210 receives a force pushing out from the extending portion 203 through the locking portion 207 and the connecting rigid body portion 220 in a direction protruding from the contact hole 107 of the housing 100. In the case where the movable contact portion 210 is further pushed by the mating substrate 400 from the state of FIG. 5, the movable contact portion 210 receives a larger pushing force from the extending portion 203. Therefore, the contact force between the movable contact portion 210 and the counterpart substrate 400 can be increased.

  Further, by adjusting the length of the movable contact portion 210 protruding from the housing 100 and the elastic force of the extending portion 203, the stroke amount in the pushing direction of the movable contact portion 210 can be adjusted.

(G) Example of Manufacturing Method The connection terminal 200 as described above can be manufactured by various methods such as an electroforming method, etching, and cutting. In particular, the electroforming method is suitable for manufacturing the connection terminal 200 that is fine and has high processing accuracy.

(2) Pushing Operation of Connection Terminal 200 into Housing 100 Next, how the connection terminal 200 accommodated in the housing 100 is further pushed into the housing 100 will be described. FIG. 9A is a cross-sectional view showing a state in which the connection terminal 200 is accommodated in the housing 100 without being pressed, and FIG. 9B is a view in which the movable contact portion 210 is pushed into the housing 100 to the maximum. It is sectional drawing which shows a mode that it is. FIG. 10 is an enlarged view showing the relationship between the movable contact portion 210 and the latch receiving portion 105 of the connection terminal 200 in FIG. FIG. 11 is an enlarged view showing the relationship between the movable contact portion 210 and the latch receiving portion 105 when the displacement of the movable contact portion 210 in the pushing direction is 1/5 of the maximum displacement amount. FIG. 12 is an enlarged view showing the relationship between the movable contact portion 210 and the latch receiving portion 105 when the displacement of the movable contact portion 210 in the pushing direction is 1/10 of the maximum displacement amount.

(2-1) Before Pushing of the Movable Contact Part 210 Before the movable contact part 210 is pushed into the housing 100 as shown in FIG. 9A, the connection terminal 200 is pressed by the movable contact part 210. It is accommodated in the housing 100 without. At this time, the first fixing portion 201 a is inserted into the locking hole 112 on the bottom surface of the housing 100, and the second fixing portion 201 b is inserted into the fixed insertion hole 111 along the first wall 101. Further, as shown in FIG. 8, the locking portion 207 of the connection terminal 200 is locked to the locking receiving portion 105 of the housing 100 by the elastic force of the extending portion 203 corresponding to the pushing length Ld.

  At this time, as shown in FIG. 10, the upper surface of the locking portion 207 is in contact with the lower surface of the locking receiving portion 105. In a state where the movable contact portion 210 is not pressed, the end surface 105a of the latch receiving portion 105 of the housing 100 and the guide portion 211 of the movable contact portion 210 are arranged so as to be in general contact with each other. Here, “arranged so as to be in contact” does not necessarily mean that they are in contact, and a gap corresponding to a dimensional tolerance between components is allowed. Specifically, the gap corresponding to the dimensional tolerance is 0.1 mm or less. Further, the gap corresponding to the dimensional tolerance means that the end surface 105a of the latch receiving portion 105 and the guide portion 211 are in contact with each other when the movable contact portion 210 is pushed into the dimensional tolerance. To do. Due to the gap corresponding to this dimensional tolerance, as shown in FIG. 10, the guide portion 211 of the movable contact portion 210 is directed from the base portion 214 toward the contact portion 215 and away from the latch receiving portion 105. It is inclined by an inclination angle θ. Here, the end surface 105a of the latch receiving portion 105 is a wall surface facing the contact hole 107 and extending in the vertical direction. Therefore, the guide portion 211 is inclined by the inclination angle θ with respect to the end surface 105 a of the latch receiving portion 105. Therefore, before the movable contact portion 210 is pushed into the housing 100, the guide portion 211 and the end surface 105a of the latch receiving portion 105 have a predetermined gap having an inclination angle θ corresponding to a dimensional tolerance. .

(2-2) Maximum displacement Dmax of movable contact portion 210
In FIG. 9B, the movable contact portion 210 is pushed most deeply into the housing 100. Compared with the state of FIG. 9A before the movable contact portion 210 is pushed into the housing 100, the movable contact portion 210 is pushed into the housing 100 by the maximum displacement amount Dmax. At this time, in the connection terminal 200, the first fixing portion 201a is inserted into the locking hole 112, and the second fixing portion 201b is inserted into the fixed insertion hole 111 and fixed. Further, the locking portion 207 of the connection terminal 200 is separated from the locking receiving portion 105 by the maximum displacement amount Dmax. The first extending portion 203a and the second extending portion 203b are also curved and compressed along the pushing direction by an amount corresponding to the maximum displacement amount Dmax. Therefore, the movable contact portion 210 receives a force that pushes upward from the first extending portion 203a and the second extending portion 203b. This pushing-up force corresponds to the elastic force of the extending portion 203 due to the pushing amount of the maximum displacement amount Dmax.

(2-3) Contact between the guide portion 211 and the end face 105a of the latch receiving portion 105 (a) Contact until reaching the maximum displacement Dmax In FIG. 11, the dashed line indicates that the movable contact portion 210 is pushed into the housing 100. Indicates a state that is not. On the other hand, a two-dot chain line indicates a state in which the movable contact portion 210 is pushed into the housing 100 by the maximum displacement amount Dmax. When the movable contact portion 210 is not pushed into the housing 100, the angle between the guide portion 211 and the end face 105a of the latch receiving portion 105 is equivalent to an inclination angle θ, as shown by a one-dot chain line in FIG. There is a gap. The inclination angle θ is a gap corresponding to the dimensional tolerance. When the dimensional tolerance is not considered in the design, the guide portion 211 and the end surface 105a of the latch receiving portion 105 are in contact with each other even when the movable contact portion 210 is not pushed into the housing 100.

  Further, when the movable contact portion 210 is pushed in with the maximum displacement amount Dmax, the guide portion 211 comes into contact with the end surface 105a of the latch receiving portion 105 as shown by a two-dot chain line in FIG. That is, when the movable contact portion 210 is pushed in with the maximum displacement amount Dmax, there is no gap between the guide portion 211 and the end surface 105a of the latch receiving portion 105.

  Eventually, the guide portion 211 of the movable contact portion 210 and the end face 105a of the latch receiving portion 105 come into contact with each other until the movable contact portion 210 is pushed into the housing 100 by the maximum displacement amount Dmax.

  More specifically, as described above, when the connection terminal 200 and the housing 100 are designed in consideration of dimensional tolerances, the guide portion 211 is inclined with respect to the end surface 105a of the latch receiving portion 105. It has an inclination of angle θ. Therefore, in a state where the movable contact portion 210 is not pressed, there is a gap having an inclination angle θ corresponding to a dimensional tolerance between the guide portion 211 and the end surface 105a of the latch receiving portion 105 of the housing 100. And before the movable contact part 210 is pushed in with the maximum displacement amount Dmax, the guide part 211 contacts the end surface 105a of the latch receiving part 105 by the force pressed against the latch receiving part 105 side from the extending part 203. At this time, when viewed from the Y direction side intersecting with the X direction in which the latch receiving portion 105 extends, the guide portion 211 and the end face 105a of the latch receiving portion 105 are in linear contact as shown in FIG. doing. More specifically, the end surface of the guide portion 211 on the locking receiving portion 105 side and the end surface 105a of the locking receiving portion 105 are in close contact with each other. Thereafter, the movable contact portion 210 is pushed into the housing 100 in a state where the guide portion 211 and the end surface 105 a of the latch receiving portion 105 are in contact with each other. That is, after the guide portion 211 and the end face 105a of the latch receiving portion 105 contact each other, the movable contact portion 210 is pushed down along the vertical direction. Therefore, the movement of the movable contact portion 210 in the X direction, that is, wiping is prevented. Thereby, it is possible to control the amount of movement of the movable contact portion 210, that is, the amount of wiping, in accordance with the inclination angle θ of the guide portion 211 and the maximum displacement amount Dmax. Therefore, contact failure between the movable contact portion 210 and the counterpart substrate 400 due to the wiping of the movable contact portion 210 can be suppressed. For example, in order to reduce the wiping amount of the movable contact portion 210, the inclination angle θ of the guide portion 211 is reduced. Conversely, to increase the wiping amount of the movable contact portion 210, the inclination angle θ of the guide portion 211 is increased.

  Furthermore, the relationship between the amount of pushing of the movable contact portion 210 into the housing 100 and the relationship between the guide portion 211 and the end face 105a of the latch receiving portion 105 will be described as follows.

(B) Contact up to 1/5 of the maximum displacement Dmax As shown by the solid line in FIG. 11, the end surface 105a of the latch receiving portion 105 and the guide portion 211 are displaced in the pushing direction of the movable contact portion 210. Contact until reaching 1/5 of the maximum displacement Dmax.

  In this case, the inclination angle θ of the guide portion 211 with respect to the end surface 105a of the lock receiving portion 105 is set to be small, and the end surface 105a of the lock receiving portion 105 immediately after the movable contact portion 210 is pushed into the housing 100. And the guide 211 come into contact with each other. Thereby, the amount of wiping of the movable contact part 210 can be suppressed.

  In FIG. 11, the alternate long and short dash line indicates a state where the movable contact portion 210 is not pushed into the housing 100. On the other hand, a two-dot chain line indicates a state in which the movable contact portion 210 is pushed into the housing 100 by the maximum displacement amount Dmax.

(C) Contact up to 1/10 of the maximum displacement Dmax As shown by the solid line in FIG. 12, the end surface 105a of the latch receiving portion 105 and the guide portion 211 are displaced in the pushing direction of the movable contact portion 210. Contact until reaching 1/10 of the maximum displacement Dmax.

  In this case, the inclination angle θ of the guide portion 211 with respect to the end surface 105a of the lock receiving portion 105 is larger than that in the case where the end surface 105a of the lock receiving portion 105 and the guide portion 211 contact each other until reaching 1/5 of the maximum displacement. Is set even smaller. Therefore, the wiping amount of the movable contact portion 210 can be further suppressed.

  In FIG. 12, the alternate long and short dash line indicates a state where the movable contact portion 210 is not pushed into the housing 100. On the other hand, a two-dot chain line indicates a state in which the movable contact portion 210 is pushed into the housing 100 by the maximum displacement amount Dmax.

(3) Assembly 500
Next, the assembly 500 in which the connector 300 and the mating substrate 400 are combined will be described. First, the counterpart substrate 400 will be described.

(3-1) Counterpart substrate 400
FIG. 13 is a perspective view of the counterpart substrate 400. 14A is a front view of the counterpart substrate 400, FIG. 14B is a rear view, FIG. 14C is a right side view, FIG. 14D is a left side view, FIG. 14E is a top view, and FIG. Is a bottom view.

  An insulating part 403 made of a resin material and a contact surface 401 partitioned by the insulating part 403 are provided on the front side of the counterpart substrate 400. The insulating portion 403 is a portion that surrounds the contact surface 401 and is electrically insulated. The insulating part 403 is made of an insulating material such as resin. The contact surface 401 is surrounded by the insulating portion 403 and is formed of a substantially rectangular recess. The insulating material is removed from the contact surface 401, and the metal material is exposed so that it can be electrically connected. In the counterpart substrate 400 of FIG. 13, four contact surfaces 401 are provided. Each of the four contact surfaces 401 in FIG. 13 corresponds to the movable contact portion 210 protruding from the four regions in FIG. Note that the shape of the contact surface 401 is not limited to a quadrangular shape as long as it can be contacted with the movable contact portion 210. For example, it may be circular.

  A substantially circular land 405 surrounded by an insulating portion 403 is provided on the bottom surface side of the counterpart substrate 400. In the land 405, the insulating material is removed, and the metal material is exposed so as to be electrically connected. The land 405 is, for example, a region that becomes a connection portion between the counterpart substrate 400 and another electronic member. Each land 405 is electrically connected to each contact surface 401 provided on the front side of the counterpart substrate 400. Note that the shape of the contact surface 401 is not limited to a circular shape as long as it can be connected to other electronic members.

(3-2) Connection of Connector 300 and Counterpart Board 400 Next, an assembly 500 in which the connector 300 and the counterpart board 400 are combined will be described. FIG. 15 is a perspective view of the assembly 500 as viewed from the bottom side of the connector 300. FIG. 16 is a perspective view of the assembly 500 as viewed from the upper surface side of the connector 300. FIG. 17 is a side view of assembly 500.

  The side where the movable contact portion 210 of the connector 300 protrudes is opposed to the front side where the contact surface 401 of the counterpart substrate 400 is provided. At this time, each of the four contact surfaces 401 of the counterpart substrate 400 is opposed to each of the four regions from which the movable contact portion 210 of the connector 300 protrudes. Since the connector 300 according to this embodiment includes two connection terminals 200 as one set, two movable contact portions 210 correspond to one contact surface 401.

Next, the connector 300 and the counterpart substrate 400 are brought close to a predetermined distance so that the contact portion 215 of the movable contact portion 210 of the connector 300 is pressed by the contact surface 401. At this time, the movable contact portion 210 is pushed into the housing 100. Therefore, the movable contact portion 210 receives a force in the direction of pushing out from the housing 100 by the extending portion 203. Thereby, the contact force between the movable contact portion 210 of the connector 300 and the contact surface 401 of the counterpart substrate 400 is improved, and conduction between the movable contact portion 210 and the contact surface 401 is ensured.

  Further, as described above, since the movement of the movable contact portion 210 in the X direction is suppressed, the position where the movable contact portion 210 and the counterpart substrate 400 come into contact can be determined precisely. As a result, when the connector 300 and the mating substrate are mounted, the allowable range of the positional accuracy in the X direction can be widened.

(4) Modification (4-1)
FIG. 18 is an enlarged view showing another example of the opposite side portion 213 of the movable contact portion 210. In the said embodiment, the opposing side part 213 is extended linearly. However, the opposing side portion 213 may be curved as shown in FIG. Since the opposing side portion 213 has a curved shape, the stress in the cross section in the direction intersecting the pushing direction of the movable contact portion 210 can be made substantially uniform in any cross section. Therefore, the strength of the movable contact portion 210 can be increased.

(4-2)
FIG. 19 is an enlarged view showing another example of the guide portion 211 of the movable contact portion 210. In the above embodiment, the guide portion 211 is slightly inclined with respect to the vertical direction. However, when dimensional tolerance or the like is not considered, the guide portion 211 may extend along the vertical direction as shown in FIG. 19, for example. That is, the guide part 211 may be formed in parallel to the end face 105 a of the latch receiving part 105.

  At this time, the movable contact portion 210 is arranged so that the guide portion 211 is positioned in the vicinity of the end surface 105 a of the latch receiving portion 105 when the connection terminal 200 is accommodated in the housing 100. The movable contact portion 210 receives a force such that the upper surface of the locking portion 207 is locked to the lower surface of the locking receiving portion 105 from the extending portion 203. Therefore, in a state where the movable contact portion 210 is not pressed, the guide portion 211 contacts the end surface 105a of the latch receiving portion 105 as shown in FIG. Then, the movable contact portion 210 is pushed into the housing 100 in parallel with the end surface 105a of the latch receiving portion 105 in a state where the guide portion 211 is in contact with the end surface 105a of the latch receiving portion 105. Therefore, similarly to the above embodiment, the movement in the direction intersecting the pushing direction of the movable contact portion 210, that is, so-called wiping can be suppressed.

  However, when the guide portion 211 has a predetermined inclination angle θ with respect to the vertical direction as in the above-described embodiment, there is less resistance when the movable contact portion 210 is inserted into the contact hole 107 of the housing 100. Easy to do.

<Other embodiment examples>
(1)
The shape of the connection terminal 200 is not limited to the connection terminal 200 shown in the above embodiment. An example of a modified example of the connection terminal 200 will be described below.

(1-1) Connection terminal 200 having one curved portion 208
FIG. 20 is a perspective view of a connection terminal 200 according to another modification. 21A is a front view of the connection terminal 200 of FIG. 20, FIG. 21B is a right side view, FIG. 21C is a left side view, and FIG. 21D is a view from the movable contact portion 210 side. FIG. 6E is a top view of the connection terminal 200, and FIG. 5E is a bottom view of the connection terminal 200 viewed from the first fixing portion 201 a side.

  The connection terminal 200 includes a fixed portion 201, a branch portion 202, an extending portion 203, a locking portion 207, a movable contact portion 210, and a connecting rigid body portion 220. The description of the same configuration as the above embodiment is omitted or simplified. In the present modification, unlike the above embodiment, the regulation connecting portion 209 is not provided.

  The fixing part 201 includes a first fixing part 201 a inserted into the locking hole 112 of the housing 100 and a second fixing part 201 b inserted into the fixed insertion hole 111.

  A branch portion 202 extends from the second fixed portion 201b. A first extending portion 203a and a second extending portion 203b extend from one end of the branching portion 202. The first extending portion 203a and the second extending portion 203b extend in a generally parallel manner with a slit 205 therebetween. The first extending portion 203a and the second extending portion 203b have one curved portion 208. The curved portion 208 is curved so as to have an opening on the second fixed portion 201b side. By having such a curved portion 208, the extending portion 203 has supple elasticity.

  The locking portion 207 is provided at a free end that is the other end of the extending portion 203 that extends from the branch portion 202. The connecting rigid body part 220 continuously connects the locking part 207 and the movable contact part 210.

  The movable contact part 210 includes a guide part 211, an opposing side part 213, a base part 214, and a contact part 215. The movable contact portion 210 is provided on the free end side of the extending portion 203 that extends from the fixed portion 201.
