Description

Connector device with terminal pressing structure

Technical Field

The present invention relates to a connector device having a terminal pressing structure, and more particularly, to a connector device having a structure in which a terminal of one connector is pressed against a predetermined portion of the other connector by a protrusion provided in a housing constituting the connectors when the connectors included in the connector device are connected to each other.

Background

An example of a connector device including the above-described configuration is disclosed in japanese patent laid-open publication No. 2015-185257. The connector device is provided with: a first connector such as a cable connector and a second connector such as a board connector which can be connected to each other. When the first connector is connected to the second connector, the first terminal of the first connector is pressed downward by being in contact with the second terminal of the second connector, particularly the elastic contact portion thereof. In order to maintain the connection state of the first terminal and the second terminal, the second housing of the second connector is provided with the following projections: the projecting portion projects in a direction opposite to the pressing direction of the elastic contact portion of the second terminal, that is, upwardly, in other words, from one side of the reference surface to one side of the elastic contact portion, and correspondingly, the following projecting portions are provided in the first housing of the first connector: the protruding portion protrudes downward, in other words, from one side of the elastic contact portion to one side of the reference surface. When the first connector and the second connector are connected, the protrusion provided on the first housing passes over the protrusion provided on the second housing, and as a result, the first connector and the second connector can be locked to each other.

The projecting portion of patent document 1 is provided mainly for locking the first connector and the second connector with each other, and when the first connector and the second connector are actually connected, the relative position of the first terminal and the second terminal is moved by the contact between the projecting portion of the first housing and the projecting portion of the second housing. More specifically, the first terminal is pressed upward by the contact of the protruding portion, that is, from the side of the reference surface to the side of the elastic contact portion. Therefore, patent document 1 discloses an example of a connector device including the above-described structure.

Patent document 1: japanese patent laid-open publication No. 2015-185257

However, since the direction in which the first terminal is pressed by the contact with the elastic contact portion of the second terminal is opposite to the direction in which the first terminal is received by the contact with the protruding portion, in this case, a force is applied to the elastic contact portion of the second terminal in the direction opposite to the direction in which the first terminal is pressed, that is, in a direction not originally intended to be unnecessary, and as a result, there is a risk that the second terminal is damaged or deteriorated. For example, in the connector device disclosed in patent document 1, it is assumed that the second terminals having a small thickness of 0.2mm or less and a small height of 2.0mm or less are used, and therefore, even a small load may cause a large damage to the second terminals or may deteriorate the spring property, and therefore, it is desirable to reduce the load applied to the second terminals and to prevent the damage or deterioration of the second terminals as much as possible.

According to the electrical connector device of this embodiment, since the direction in which the first terminal is pressed by contact with the elastic contact portion is the same as the direction in which the first housing supporting the first terminal is pressed by contact with the second housing, the force applied to the second terminal when the first terminal is in contact with the elastic contact portion of the second terminal can be reduced, and damage or deterioration of the second terminal caused by insertion and removal of the first connector and the second connector can be prevented.

In the connector device according to the above-described embodiment, the first housing may have a first protruding portion protruding in the orthogonal direction on a side opposite to a side close to the reference surface, and the first protruding portion may be in contact with the second protruding portion.

In the connector device according to the above-described embodiment, the reference surface may be formed by the second housing and/or the second terminal.

In the connector device according to the above-described embodiment, it is preferable that the elastic contact portion is formed of a metal plate, and a contact surface of the elastic contact portion with the first terminal is a surface having a plate thickness of the metal plate.

By providing the plate surface as the contact surface, strength can be easily secured even when the second terminal is small.

In the electrical connector device according to the above-described embodiment, each of the plurality of second terminals may be formed of a metal plate, and the second terminals may be arranged adjacent to each other in a state where plate surfaces of the metal plates face each other at least in the elastic contact portion.

In the connector device according to the above-described embodiment, it is preferable that a recess recessed toward a side close to the reference surface in the orthogonal direction is provided in a portion of the first terminal which comes into contact with the elastic contact portion.

With this configuration, the load applied to the second terminal can be reduced.

In the connector device according to the above-described embodiment, the second terminal may include: a movable piece on which the elastic contact portion is formed; and a fixed piece connected with the movable piece.

Further, the movable piece may include a substantially L-shaped portion, the fixed piece may include a substantially linear portion formed along the insertion direction, and the movable piece and the fixed piece may have a substantially U-shaped portion as a whole in a side view.

Detailed Description

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. For convenience of explanation, preferred embodiments are shown, but the present invention is not limited thereto.

The connector device 1 of the present invention is constituted by a set of a cable connector as a first connector and a substrate connector as a second connector which can be fitted to each other. Fig. 1 is a perspective view showing a state before the cable connector 20 and the board connector 50 are fitted to each other, and fig. 2 is a plan view showing the state after the fitting. The cable connector 20 is used in a state of being fixed to one end of the cable 11, while the board connector 50 is used in a state of being fixed to the board 13. The cable connector 20 and the board connector 50 have left-right symmetrical shapes, respectively.

The cable connector 20 mainly includes: a cable housing 21 extending in a terminal arrangement direction (long side direction) "γ"; and a plurality of cable terminals 40 of the same shape supported by the cable housing 21 and arranged along the terminal arrangement direction "γ". The term "terminal arrangement direction" in the present specification includes not only a case where the cable terminals 40 are arranged in a straight line but also a case where the cable terminals are arranged in a zigzag shape, for example.

The cable housing 21 is mainly composed of: a body portion 29 extending in the terminal arrangement direction "γ"; and a fitting projection 22 provided on the front side of the body portion 29, in other words, on the fitting side in the fitting direction "α" of the cable connector 20 and the board connector 50. A plurality of cable terminals 40 are arranged substantially in a row at a predetermined pitch along the terminal arrangement direction "γ" in the fitting projection 22.

The main body portion 29 is formed into, for example, a substantially box-shaped body, and the fitting projection 22 is formed into a plate-shaped body which is thinner in the vertical direction "β" than the main body portion 29, in other words, in the direction orthogonal to both the fitting direction "α" and the terminal arrangement direction "γ", and which is narrower in the terminal arrangement direction "γ". The cable housing 21 is formed in a substantially convex shape in side view as a whole by the main body portion 29 and the fitting convex portion 22. The fitting convex portion 22 is provided with substantially semicircular protruding portions 25 on the outer left and right surfaces in the terminal arrangement direction "γ". The projecting portion 25 projects upward.

The fitting projection 22 is inserted into an insertion space 52 provided in a board housing 51 of the board connector 50 along a fitting direction (insertion direction) "α" when the cable connector 20 is fitted to the board connector 50. As a result, a part of the cable terminal 40 is also inserted into the insertion space 52. The upper surface of the fitting projection 22 inserted into the insertion space 52 is formed in a comb shape by removing a part along the fitting direction "α" at the arrangement position of each cable terminal 40, and a part of the upper surface of each cable terminal 40 is exposed to the outside of the cable housing 21 from the gap 28 of the comb. Each cable terminal 40 is in contact with a terminal on the substrate connector 50 side through the exposed portion and the like.

A plurality of terminal insertion holes 24 are provided on the rear side of the body portion 29. The cable terminal 40 and a part of the cable 11 swaged to one end of the cable terminal 40 are inserted into the cable housing 21 through the terminal insertion holes 24 along the fitting direction "α".

Fig. 3 (a) and (b) show perspective views of the cable terminal 40. The cable terminals 40 are each formed into a substantially cylindrical shape by punching and bending a single metal plate. An opening 45 for receiving and providing one end of the cable 11 is provided on the rear side of the fitting direction "α" of the cable terminal 40. The cable 11 is fixed thereto by caulking the opening 45 in a state where one end of the cable 11 is accommodated.

On the other hand, an upper contact surface 47 and a bottom contact surface 46 are formed on the front side of the cable terminal 40 in the fitting direction "α" and are separated from each other in the vertical direction "β". The cable terminal 40 is contactable with the board terminal 60 of the board connector 50 on the upper contact surface 47 and the bottom contact surface 46.

The upper contact surface 47 of the cable terminal 40 is provided with a recess 41 into which a part of the board terminal 60 is fitted so as to be reliably brought into contact with the board terminal 60 of the board connector 50. In order to alleviate the contact with the board terminal 60, the tapered portion 42 is preferably provided at the tip of the upper contact surface 47.

The locking piece 43 is provided on the rear side of the bottom contact surface 46 of the cable terminal 40 in a downwardly protruding state. The cable terminal 40 is locked to the cable housing 21 by the locking piece 43. A recess 44 is provided on the rear side of the locking piece 43. In order to dispose cable terminal 40 at a predetermined position inside cable jacket 21, locking lever 23 provided in cable jacket 21 can be hooked to concave portion 44.

Fig. 4 is a partially enlarged perspective view of cable jacket 21 as viewed from the bottom surface side. The lock lever 23 is provided along the fitting direction "α" in a state of being supported by the body portion 29 in a cantilever shape, and a tip end thereof is positioned in the vicinity of a middle of the fitting direction "α" of the fitting convex portion 22. When the cable terminal 40 is inserted into the cable housing 21 through the terminal insertion opening 24, the locking lever 23 is fitted into the concave portion 44 of the cable terminal 40 by its elastic action (see fig. 3). As a result, the cable terminal 40 is positioned at a predetermined position of the cable housing 21. The bottom surface 23a of the lock lever 23 is a flat surface corresponding to at least a part of a surface 56 (see fig. 1) of the insertion space 52 of the board connector 50 into which the fitting projection 22 is inserted. Similarly, the bottom surface 27 of at least a part of the front side in the fitting direction "α" of the fitting projection 22 is also a flat surface corresponding to a surface (reference surface) 54 (see fig. 1) of at least a part of the insertion space 52 of the board connector 50 into which the fitting projection 22 is inserted.

Fig. 5 shows a sectional perspective view of the board connector 50. The position of the cross-section in this figure can also be considered to correspond to the line I-I in fig. 2. The board connector 50 mainly includes: a substrate housing 51 extending in the terminal arrangement direction "γ"; a plurality of substrate terminals 60 of the same shape supported by the substrate case 51; and reinforcing metal fittings 12 provided on the left and right outer surfaces of the substrate case 51 in the terminal arrangement direction "γ". The board housing 51 is fixed to the board 13 by the board terminals 60 and the reinforcing metal fittings 12 (see fig. 1).

In order to dispose the board terminal 60 in the board housing 51, a plurality of terminal insertion holes 66 are provided on the rear side of the board housing 51. The board terminals 60 are inserted into the board housing 51 through the terminal insertion holes 66 along the fitting direction "α", and are arranged in the insertion space 52 into which the fitting convex portion 22 of the cable connector 20 is inserted, substantially in a row at a predetermined pitch along the terminal arrangement direction "γ" corresponding to each of the cable terminals 40 of the cable connector 20.

The board terminals 60 are formed in a plate shape by punching a single metal plate, and are arranged adjacent to each other in the board housing 51 in a state where plate surfaces of the respective metal plates face each other in the terminal arrangement direction "γ". Each board terminal 60 includes a support portion 61, an elastic arm portion 62 connected to the support portion 61, and a mounting portion 63.

The mounting portion 63 is a portion provided in the vicinity of the connection portion between the support portion 61 and the elastic arm portion 62, and is used to solder the board terminal 60 to a board. The substrate terminal 60 can be fixed to the substrate and can be electrically connected to a predetermined portion of the substrate by soldering the mounting portion 63 to the predetermined portion of the substrate.

The support portion 61 is a portion used as a fixing piece, includes a substantially linear portion formed along the fitting direction "α", and has a locking protrusion 61a that is locked to the substrate case 51 in the vicinity of a connection portion between the support portion 61 and the elastic arm portion 62, as in the attachment portion 63. The substrate terminal 60 is fixed to the substrate case 51 by press-fitting the locking protrusion 61a into the terminal insertion hole 66 of the substrate case 51.

The elastic arm portion 62 is a portion used as a movable piece, and includes a substantially L-shaped portion extending in a cantilever manner from the support portion 61, and a substantially U-shaped portion when viewed from the side is formed by the support portion 61 and the elastic arm portion 62. The inside of the approximate U-shape forms an insertion space 65 into which a predetermined portion of the cable terminal 40 of the cable connector 50, particularly the upper contact surface 47 and the bottom contact surface 46 thereof, is inserted. The cable terminal 40 is inserted into the insertion space 65 to thereby contact the substrate terminal 60. In order to reliably achieve electrical contact with the cable terminal 40, an elastic contact portion 62a is provided at the leading end of the elastic arm portion 62. A surface having a plate thickness of a metal plate, i.e., a fracture surface, is used as a contact surface 62b of the elastic contact portion 62a, which is in contact with the cable terminal 40. By setting the contact surface to a fracture surface, strength can be ensured even when the board terminal 60 is small. When the contact is made with the cable terminal 40, the elastic contact portion 62a is temporarily lifted upward by the elastic action of the elastic arm portion 62 by the contact with the cable terminal 40, for example, the tapered portion 42 at the tip end thereof, and then fitted into the recess 41 provided in the upper contact surface 47 of the cable terminal 40. By fitting the elastic contact portion 62a into the recess 41, the contact between the board terminal 60 and the cable terminal 40 can be stabilized. In the insertion space 52, a relief space 57 for preventing contact is provided in consideration of the lifting of the elastic contact portion 62 a.

A flat reference surface (sliding contact surface) 54 defined by two directions, i.e., a fitting direction "α" and a terminal arrangement direction "γ", is provided in the insertion space 52. When the fitting projection 22 is inserted into the insertion space 52, the bottom surface 27 (see fig. 4) on the front side of the fitting projection 22 slides on the reference surface 54 along the fitting direction "α" and is finally placed thereon. In order to guide the bottom surface 27 of the fitting convex portion 22, a tapered portion 54a is preferably provided on the front side of the reference surface 54. The reference surface 54 is positioned below the vertical direction "β" in a state of being separated from the elastic contact portion 62a in the vertical direction "β". Since the reference surface 54 and the bottom surface 27 of the fitting projection 22 are both formed as flat surfaces, the fitting projection 22 is held by the insertion space 52 in a state of being finally placed on the reference surface 54 by bringing the flat surfaces into sliding contact with each other.

Further, a flat surface 56 is provided in the insertion space 52 along the fitting direction "α", and when the fitting convex portion 22 is inserted into the insertion space 52, the flat surface 56 is finally placed on the bottom surface 23a (see fig. 4) of the lock lever 23 provided in the vicinity of the middle of the fitting convex portion 22 in sliding contact therewith. In order to guide the bottom surface 23a of the lock lever 23, a tapered portion 56a is preferably provided on the front side of the surface 56. Since the surface 56 and the bottom surface 23a of the lock lever 23 are formed as flat surfaces, the lock lever 23 is held by the insertion space 52 in a state of being finally placed on the surface 56 by bringing the flat surfaces into sliding contact with each other. Further, the reference surface 54 is positioned slightly higher than the surface 56 in the vertical direction "β" due to the step between the bottom surface 27 of the fitting convex portion 22 and the bottom surface 23a of the lock lever 23.

On the left and right inner surfaces in the terminal arrangement direction "γ" of the insertion space 52, substantially semicircular protruding portions 55 are provided corresponding to the protruding portions 25 of the fitting convex portion 22, respectively. The projecting portion 55 projects to the side opposite to the projecting portion 25, in other words, to the side opposite to the side close to the upper reference surface 54 in the vertical direction "β".

The functions of the

projections

25 and 55 will be described with reference to fig. 6 to 9. Fig. 6 and 7 are a sectional view taken along line I-I and a sectional view taken along line II-II of fig. 2, respectively, and show a state after the cable connector 20 is fitted to the board connector 50, in other words, after the cable terminal 40 is inserted into the insertion space 65 of the board terminal 60. On the other hand, fig. 8 and 9 are a view corresponding to a cross-sectional view taken along line I-I of fig. 2 and a view corresponding to a cross-sectional view taken along line II-II, respectively, and show a state before the cable connector 20 is completely fitted to the board connector 50, and more specifically, a state after the fitting projection 22 of the cable housing 21 is inserted into the insertion space 52 of the board housing 51 and the cable terminal 40, particularly the tapered portion 42 provided at the distal end thereof, is brought into contact with the elastic contact portion 62a of the board terminal 60, unlike fig. 6 and 7.

As shown in fig. 8, when the tapered portion 42 of the cable terminal 40 comes into contact with the elastic contact portion 62a of the board terminal 60, the cable terminal 40 is pressed toward the reference surface 54 in the vertical direction "β" by the contact with the elastic contact portion 62 a. Further, when the cable terminal 40 is pressed in the vertical direction "β" toward the side close to the reference surface 54 by contact with the elastic contact portion 62a, as shown in fig. 9, the protruding portion 25 of the cable housing 21 comes into contact with the protruding portion 55 of the substrate housing 51, and by this contact, the cable housing 21, specifically, the cable terminal 40 supported by the cable housing 21 is also pressed in the vertical direction "β" toward the side close to the reference surface 54. As described above, according to the present configuration, since the direction in which the cable terminal 40 is pressed by contact with the elastic contact portion 62a is the same as the direction in which the cable terminal 40 supported by the cable housing 21, specifically, the cable housing 21 is pressed by contact between the protruding portion 25 and the protruding portion 55, the force applied to the board terminal 60 when the cable terminal 40 is in contact with the elastic contact portion 62a can be reduced, and damage or deterioration of the board terminal 60 caused by insertion and removal of the cable connector and the board connector can be reduced.

In particular, in the present embodiment, the moment when the cable terminal 40 contacts the elastic contact portion 62a and the moment when the protruding portion 25 of the cable housing 21 contacts the protruding portion 55 of the board housing 51 are substantially the same, and thus the load applied to the board terminal 60 can be more effectively reduced. However, the above timings are not necessarily the same.

When the cable connector 20 is fitted to the board connector 50, as shown in fig. 6, the cable terminal 40 is inserted into the insertion space 65 of the board terminal 60, and as a result, the elastic contact portion 62a of the board terminal 60 is exposed from the cable housing 21 and fitted into the recess 41 of the upper contact surface 47 of the cable terminal 40. As a result, the board terminal 60 and the cable terminal 40 are more reliably connected. The concave portion 41 provided in the cable terminal 40 is provided in a state of being recessed toward the side close to the reference surface 54 in the vertical direction "β" at a portion where the elastic contact portion 62a comes into contact, and therefore, also has a function of reducing a load applied to the board terminal 60. Since the concave portion 41 is not provided on the lower contact surface 46 of the cable terminal 40 but on the upper contact surface 47, the contact between the cable terminal 40 and the board terminal 60, specifically, the contact between the lower contact surface 46 of the cable terminal 40 and the surface 61b of the support portion 61 of the board terminal 60 is not hindered, and therefore, even when the concave portion is provided, the cable terminal 40 is smoothly inserted into the insertion space 65 of the board terminal 60. When the cable connector 20 is fitted to the board connector 50, the fitting state of the cable connector 20 to the board connector 50, specifically, the connection state of the board terminal 60 to the cable terminal 40 is locked by the

projections

25 and 55 as shown in fig. 7, and therefore, when the fitting state of the cable connector 20 to the board connector 50 is released, the projection 25 needs to interfere with the projection 55 and the projection 25 needs to pass over the projection 55. In this way, the

projections

25 and 55 not only have a function of reducing a load applied to the board terminal 60, but also function as a lock mechanism.

The present invention is not limited to the above embodiment, and various other modifications can be made.

For example, in the above-described embodiment, the protruding portion 55 of the board housing 51 is provided on the left and right inner side surfaces in the terminal arrangement direction "γ" of the insertion space 52, in other words, on the outer side of the arrangement of the board terminals 60 in the direction along the terminal arrangement direction "γ", but these may be disposed in the middle of the arrangement of the board terminals 60, or may be disposed in the middle in addition to the left and right inner side surfaces, or may be disposed only in the middle without being provided on the left and right inner side surfaces.

The projecting portion 25 of the cable cover 21 is not essential, and it suffices that the cable terminal 40 is pressed toward the reference surface 54 by the contact between the cable cover 21 and the projecting portion 55 of the board cover 51 even if the projecting portion is not provided. Therefore, it suffices that the cable cover 21 has a portion abutting against the protruding portion 55 of the substrate cover 51.

In the above-described embodiment, the reference surface 54 is provided on the board housing 51, but the reference surface 54 may be formed by the board terminal 60, specifically, the flat surface 61b (see fig. 5) of the support portion 61 provided on the board terminal 60, or the reference surface 54 may be formed by the flat surface 61b and the reference surface 54.
