Description

[Technical Field]

[0001] The present invention relates to a connector structure having a configuration in which terminals are fitted into a connector housing. [Background technology]

[0002] In automobiles and other applications, when a large number of wirings (cables) are connected to a large number of electrical components, a large number of connectors are used to connect and secure the terminals of the wirings together. Such connectors are required to securely secure each terminal, and to be able to securely connect the wirings by connecting the connector with the secured terminals to another connector.

[0003] Such connectors include male and female connectors, which are mated and coupled to connect the wiring on the male connector side and the wiring on the female connector side. Both connectors are constructed with metal terminal fittings, to which the wiring is connected (or which become part of the wiring), fixed in a connector housing made of a resin material. The terminal fittings are fixed by being inserted into the connector housing, and are locked in lances formed on the connector housing to prevent them from falling out after being fixed.

[0004] In this case, when the connector (male or female connector) is later connected, it is required that the terminal fittings are securely fixed to the connector housing. To achieve this, the aforementioned lance alone is not sufficient to prevent them from coming loose; the terminal fittings must be fixed in the correct position relative to the connector housing and then locked by the lance. For this reason, a structure is adopted that prevents the terminal fittings from being in an insufficiently fixed state (semi-fixed state), or that makes it easy to recognize this state.

[0005] Patent Document 1 describes a structure in which a retainer manufactured separately from a connector housing is used, and the terminal fittings are attached as described above when the connector housing and the retainer are combined. With this structure, when the terminal fittings are in a semi-fixed state, the retainer is not fixed to the connector housing, so the worker can easily recognize that the terminal fittings are in a semi-fixed state. This prevents the terminal fittings from becoming semi-fixed. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-252875 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0007] In the technology described in Patent Document 1, whether or not the semi-fixed state can be properly recognized depends on the state of engagement between the retainer, which is a new component, and the connector housing. Therefore, if there is backlash between the retainer and the connector housing, for example, it may not be possible to properly recognize this. For this reason, a structure that more reliably fixes the terminal fittings to the connector housing is desired.

[0008] The present invention has been made in view of the above circumstances, and has as its object to solve the above problems. [Means for solving the problem]

[0009] The present invention provides a connector having a configuration in which terminal fittings made of a metal material are mounted in a connector housing made of a resin material, wherein the terminal fittings are configured to be mounted in terminal fitting accommodating sections provided in the connector housing from one side to the other in a first direction, and a fixing spring section, which is a leaf spring, is provided on one side of the terminal fittings in a second direction intersecting with the first direction and protruding toward the one side from a lower surface of the terminal fitting, which is a surface intersecting with the second direction on the one side, and On the one side in the first direction, there is provided a terminal fitting fixing surface that intersects with the second direction and is arranged to abut against the lower surface of the terminal fitting when the terminal fitting is attached, and a step portion that is arranged along the second direction on the one side of the terminal fitting fixing surface in the first direction and toward the one side in the second direction, and when the terminal fitting is moved from the one side to the other side in the first direction within the terminal fitting accommodating portion, the step portion engages with the fixing spring portion to bend the fixing spring portion toward the other side in the second direction. The fixing spring portion may be configured by cutting the lower surface of the terminal fitting on the one side in the first direction and bending the lower surface with the other side in the first direction as a fulcrum. The fixing spring portion may have a shape that is bent from the other side in the first direction toward the one side in the second direction, and from the one side in the first direction toward the other side in the second direction. The terminal fitting may be provided with a connecting spring portion which is a leaf spring protruding from the upper surface of the terminal fitting, which is a surface which intersects with the second direction on the other side in the second direction, to one side in the second direction, and when another connector is connected from the other side toward the one side in the first direction, the terminal of the other connector may be clamped between the connecting spring portion and the fixing spring portion. A lance may be provided within the terminal fitting accommodating portion in the connector housing, which engages with the terminal fitting to limit movement of the terminal fitting toward the one side in the first direction when the fixing spring portion is bent toward the other side in the second direction by moving the terminal fitting from the one side to the other side in the first direction within the terminal fitting accommodating portion, causing the fixing spring portion to abut against the terminal fitting fixing surface. A wiring fixing portion for fixing a wiring connected to the terminal fitting is provided on one side of the terminal fitting in the first direction, and when the terminal fitting is moved from the one side to the other side in the first direction within the terminal fitting accommodating portion, the wiring fixing portion is located outside the terminal fitting accommodating portion when viewed from the second direction before the lance is engaged with the terminal fitting, and the wiring fixing portion is located inside the terminal fitting accommodating portion when the lance is engaged with the terminal fitting. [Effects of the Invention]

[0010] Since the present invention is configured as described above, it is possible to obtain a connector in which the terminal fittings are more reliably fixed to the connector housing. [Brief explanation of the drawings]

[0012] A connector according to an embodiment of the present invention will be described. This connector is a female connector, in which female terminal fittings are attached to and fixed in a connector housing made of a resin material. At this time, the terminal fittings are securely fixed to the connector housing, and no new component (retainer) is used, as in the technology described in Patent Document 1.

[0013] FIG. 1 is a perspective view of the connector 1, seen from the rear side (a) and front side (b). Here, the extension direction (front-to-back direction) of the terminal fittings 10 or the wiring 40 fixed thereto is defined as the x-direction (first direction), with the negative side (one side) of the x-direction defined as the rear side and the positive side (the other side) defined as the front side. The terminal fittings 10 are fixed to a connector housing (hereinafter referred to as housing) 20. The connector 1 is a two-terminal type, and two terminal fittings 10 are actually fixed to the housing 20 at two locations along the y-direction in FIG. 1, but only one of the terminal fittings 10, located on the positive side of the y-direction, is shown here as being fixed. In FIG. 1, the up-down direction is defined as the z-direction (second direction).

[0014] 1, terminal fitting 10 is inserted and fixed in terminal fitting accommodating portion 20A, which is formed to penetrate housing 20 in the x direction, from the negative side (rear side) in the x direction to the positive side (front side). Meanwhile, a connector (male connector: not shown) to be connected to this connector 1 is connected from the positive side in the x direction. At this time, a terminal provided on this male connector is fitted into the portion of terminal fitting 10 on the positive side in the x direction, and is electrically connected.

[0015] FIG. 2 is a perspective view of the terminal fitting 10 with the wiring 40 fixed thereto, viewed from three different directions. The terminal fitting 10 is formed by machining a metal plate (e.g., a copper alloy plate). As shown in FIGS. 2(a) and 2(b), the terminal fitting 10 has wiring fixing portions 11A and 11B on the negative side in the x direction for fixing the wiring 40. The wiring 40 is configured by a core wire (conductor) 41 covered with an insulating coating layer 42 along its extension direction. The coating layer 42 near the end of the wiring 40 on the positive side in the x direction is removed to expose the core wire 41. The portion of the wiring 40 where the coating layer 42 is not removed at the wiring fixing portion 11A on the most negative side in the x direction of the terminal fitting 10, and the portion of the core wire 41 where the coating layer 42 is removed at the wiring fixing portion 11B on the positive side of the wiring fixing portion 11A in the x direction are fixed by crimping. This allows the wiring 40 to be firmly fixed to the terminal fitting 10.

[0016] Meanwhile, a structure for connecting the terminal fitting 10 to a metal terminal (male terminal) of a male connector is formed on the positive side in the x direction of the terminal fitting 10. In FIG. 1, this structure is located inside the terminal fitting accommodating portion 20A. As shown in FIG. 2(c), this structure forms a first spring (connecting spring portion) 13. The first spring 13 is formed by bending a portion of the upper surface 12 of the terminal fitting, with the negative side in the x direction as a fulcrum, at an angle of 90° or more toward the negative side in the z direction. Therefore, the first spring 13 functions as a leaf spring that is closed on the positive side in the x direction and open on the negative side in the x direction.

[0017] Meanwhile, on the lower surface (negative side in the z direction: one side in the third direction) of the terminal fitting 10, male terminal locking portions 14 are formed at two locations along the y direction, protruding to the positive side in the z direction (the other side in the third direction) so as to face the first spring 13. With this structure, the elastic force of the first spring 13 allows a plate-shaped male terminal that has entered from the positive side in the x direction to be clamped and fixed between the first spring 13 and the male terminal locking portions 14. The actual configuration of this will be described later.

[0018] Furthermore, a structure for properly fixing the terminal fitting 10 to the terminal fitting accommodating portion 20A is provided at a portion of the terminal fitting 10 located inside the terminal fitting accommodating portion 20A. This structure includes a second spring (fixing spring portion) 15, as shown in FIG. 2(b). The second spring 15 is located between the two male terminal locking portions 14 in the y direction and, opposite to the first spring 13, is a leaf spring formed by bending the terminal fitting lower surface 16, which is the lower surface (the surface on the negative side in the z direction) of the terminal fitting 10. The bending direction is opposite to that of the first spring 13, and a portion of the terminal fitting lower surface 16 is bent with the positive side of the x direction as a fulcrum so that the portion on the negative side in the x direction protrudes toward the negative side in the z direction, and then this portion on the negative side in the x direction is further bent toward the positive side in the z direction at an angle of 90° or more. This structure will be described in detail later.

[0019] 3 is a perspective view of the terminal fitting accommodating portion 20A of the housing 20 as seen from the rear (negative side in the x-direction). The surfaces that come into contact with the terminal fitting 10 from below (negative side in the z-direction) are a first accommodating portion lower surface (terminal fitting fixing surface) 24, which is the surface on the far side (positive side in the x-direction), and a second accommodating portion lower surface 25, which is the surface on the near side (negative side in the x-direction) set lower than the first accommodating portion lower surface 24, and these are connected by a step portion 21. In addition, to prevent the terminal fitting 10 from falling out of the terminal fitting accommodating portion 20A to the rear side (negative side in the x-direction) once it has been installed, a lance 22 is formed in the terminal fitting accommodating portion 20A so as to protrude from the upper surface (positive side in the z-direction) to the lower surface (negative side in the z-direction). As will be described later, when the terminal fitting 10 is at a predetermined position in the x-direction inside the terminal fitting accommodating portion 20A, the lance 22 is locked by a lance locking portion 17, which is a part of the terminal fitting upper surface 12 that is partially open on the negative x-direction side of the first spring 13 in Figures 2(a) and 2(c). This prevents the terminal fitting 10 from slipping out to the negative x-direction side (rearward).

[0020] The manner in which the terminal fitting 10 is mounted in the terminal fitting accommodating portion 20A will be described below. Figures 4(a) and 4(b) are cross-sectional views, taken along the x and z directions, of the terminal fitting 10 at the location where the second spring 15 is formed and the terminal fitting accommodating portion 20A (housing 20) at the portion where the terminal fitting 10 is mounted. As will be described later, the first spring 13, the second spring 15, and the housing 20 of the terminal fitting 10 are elastically deformed, but the state shown in Figure 4 shows a state in which no force is applied to them.

[0021] In the terminal fitting 10 (FIG. 4(a)), each part is shown separated, but in reality, these parts are connected and integrated outside the range of the illustration. As described above, a part of the terminal fitting upper surface 12 is bent downward (negative side in the z direction) with the negative side in the x direction as a fulcrum, thereby forming the first spring 13 that protrudes downward from the terminal fitting upper surface 12. On the left side (rear side, negative side in the z direction) of the first spring 13 in the drawing, a lance locking part 17 is formed, which is an opening on the terminal fitting upper surface 12.

[0022] As described above, the second spring 15 is formed by first bending a part of the lower surface 16 of the terminal metal downward (toward the negative z-direction) with the positive x-direction side as a fulcrum, and then bending it upward (toward the positive z-direction). Therefore, as shown in Fig. 4(a), the second spring 15 is formed to protrude downward from the lower surface 16 of the terminal metal.

[0023] An upper surface 23 of the housing 20 (terminal fitting accommodating portion 20A) is formed on the upper side (FIG. 4(b)) of the housing 20, which abuts against the upper surface 12 of the terminal fitting when the terminal fitting 10 is attached. The lance 22 is formed on the positive side of the accommodating portion upper surface 23 in the x direction (the rear side when the terminal fitting 10 is attached) so as to protrude downward from the accommodating portion upper surface 23 when no force is applied. Note that the portion of the housing 20 where the lance 22 is formed is thin-walled above the lance 22 to facilitate elastic deformation of the lance 22.

[0024] On the other hand, on the lower side ( FIG. 4( b) ) of the housing 20 (terminal fitting accommodating portion 20A), a first accommodating portion lower surface (terminal fitting fixing surface) 24 is formed, which abuts against the terminal fitting lower surface 16 when the terminal fitting 10 is attached. A second accommodating portion lower surface 25, which is lower than the first accommodating portion lower surface 24 (located on the negative side of the z direction) is formed on the negative side of the first accommodating portion lower surface 24 in the x direction (the side closer to the user when attaching the terminal fitting 10). This forms a step 21 at the boundary between the first accommodating portion lower surface 24 and the second accommodating portion lower surface 25. As described above, the second spring 15 protrudes below the terminal fitting lower surface 16, but when the terminal fitting 10 is attached to the terminal fitting accommodating portion 20A, the terminal fitting lower surface 16 on the positive side of the x direction slides on the first accommodating portion lower surface 24, and the second spring 15 moves on the second accommodating portion lower surface 25. As will be described later, the step portion 21 functions to bend the second spring 15 upward (toward the positive z-direction) when the terminal fitting 10 is attached.

[0025] The manner in which the terminal fitting 10 is mounted in the terminal fitting accommodating portion 20A (housing 20) will be described based on the structure shown in Fig. 4. Fig. 5 is a cross-sectional view showing the process of this transformation.

[0026] First, as shown in Fig. 5(a), the terminal fitting 10 is inserted into the terminal fitting accommodation portion 20A from the negative side to the positive side in the x direction. In this state, the accommodation portion upper surface 23 contacts and guides the terminal fitting upper surface 12 on the upper side. Meanwhile, the accommodation portion second lower surface 25 guides the second spring 15 on the lower side.

[0027] 5(b), when the terminal fitting 10 is further pushed in, the upper surface 12 of the terminal fitting comes into contact with the lance 22 protruding downward, but as described above, the portion of the housing 20 where the lance 22 is formed is easily elastically deformed, so the lance 22 is pushed up by the upper surface 12 of the terminal fitting and deforms so as to move upward, and the lower end of the lance 22 (lower lance end 22A) moves above the upper surface 12 of the terminal fitting. Therefore, the terminal fitting 10 can be pushed in further from this state.

[0028] If the terminal 10 is further pushed in from this state, the second spring 15 abuts against the stepped portion 21, and a force indicated by arrow F1 acts, tilting the rear end of the second spring 15 upward, as shown in FIG. 5(c). Therefore, when pushing the terminal 10 from the negative x-axis, the operator experiences a reaction force indicated by arrow F2. In the case of FIG. 5(b), the operator also experiences a reaction force due to the deformation of the lance 22. However, since the lance 22 is made of resin and the second spring 15 is made of metal and has a large elastic force, the reaction force experienced by the operator in the case of FIG. 5(c) is greater than that experienced in the case of FIG. 5(b). Therefore, the operator experiences greater resistance when pushing the terminal 10, and the operator can recognize that the terminal 10 is currently in the state of FIG. 5(c) by the resistance felt when pushing the terminal 10. To facilitate this operation, the angle of the step portion 21 relative to the x direction (or the first lower surface 24 of the accommodation portion) is set appropriately.

[0029] If the terminal 10 is further pushed in from this state, the rear end of the second spring 15 deforms and moves further upward, and as shown in FIG. 5(d), there is no longer any portion of the second spring 15 that abuts against the stepped portion 21. Therefore, in this state, the terminal lower surface 16 can be moved on the first lower surface 24 of the receiving section. In this state, the terminal 10 is no longer subjected to the elastic force of the second spring 15 in the x direction, and therefore there is no reaction force indicated by arrow F2 in FIG. 5(c). Therefore, the resistance when the operator pushes in the terminal 10 is smaller than in the state of FIG. 5(c). Therefore, the operator can recognize the change from the state of FIG. 5(c) to the state of FIG. 5(d) by the feel of the resistance.

[0030] If the terminal fitting 10 is further pushed in from this state, the state of the lower side remains unchanged and the lance lower end 22A reaches the lance locking portion 17 (the opening in the terminal fitting upper surface 12) as shown in Figure 5(e). As a result, the elastic force of the lance 22 restores it to the state shown in Figure 5(a), and the lance lower end 22A moves to a position lower than the terminal fitting upper surface 12. As a result, the movement of the terminal fitting 10 to the negative side in the x direction is restricted by the lance 22.

[0031] In the above process, the worker can easily recognize the changes in state, particularly those shown in Figures 5(b) to 5(d), and the state in which the lance 22 is then engaged with the terminal fitting 10 indicates that the terminal fitting 10 is properly attached to the housing 20.

[0032] 5(e), the second spring 15 of the terminal fitting 10 abuts against the first lower surface 24 of the accommodating portion. In this case, the downward elastic force of the second spring 15 prevents rattle from occurring between the terminal fitting 10 and the first lower surface 24 of the accommodating portion. In other words, rattle of the terminal fitting 10 is reduced after the terminal fitting 10 is attached to the housing 20. This makes it possible to prevent, for example, abnormal noise (resonance) from occurring when the connector 1 is used.

[0033] As described above, the terminal fitting 10 has wire fixing portions 11A and 11B on the negative side in the x-direction for fixing the wire 40. Figures 6(a) and 6(b) show the entire connector 1 including the wire fixing portions 11A and 11B, enlarged from the structure shown in Figures 5(b) and 5(e). In the case shown in Figure 6(b) where the terminal fitting 10 has reached the appropriate position, the wire fixing portion 11A is located inside the terminal fitting accommodating portion 20A. In contrast, in the case shown in Figure 6(a) where the terminal fitting 10 has not yet reached the appropriate position, the wire fixing portion 11A is located outside the terminal fitting accommodating portion 20A. In other words, by setting the position of the wire fixing portion 11A in this way, the situation shown in Figure 5(e) can be more reliably recognized.

[0034] The above has shown the state when the terminal fitting 10 is attached to the housing 20. Next, the state when this connector 1 is coupled to another connector (male connector) will be described. FIG. 7 is a diagram showing the state when another connector is coupled to the structure of FIG. 6(b) in this manner. Here, the connector housing 90 of the connector 9 is coupled to the connector 1 from the positive side in the x direction. The terminal on the connector 90 side is a terminal tab (terminal) 91, which is a plate-shaped male terminal extending in the x and y directions. In FIG. 7, a cross section of the terminal tab 91 in the thickness direction is shown, and other structures on the connector 9 side are not shown.

[0035] As described above, at this time, the terminal tab 91 is sandwiched and fixed between the first spring 13 and the male terminal locking portion 14. As shown in FIG. 2(c), the male terminal locking portion 14 and the second spring 15 are not provided on the same plane in the x and z directions, and therefore the male terminal locking portion 14 is indicated by a dotted line in FIG. 7. In the structure of FIG. 7, in addition to the male terminal locking portion 14, the second spring 15 bent toward the positive z direction also abuts against the terminal tab 91. That is, in the above structure, the second spring 15 is used not only to fix the terminal fitting 10 but also to particularly stably fix the terminal tab 91 to the terminal fitting 10 to ensure electrical continuity. This also reduces play between the terminal tab 91 (connector 1) and the terminal tab 91 (connector 9).

[0036] The above configuration is realized by manufacturing terminal fittings 10 having the structure shown in Fig. 2 and the corresponding housing 20. In this case, terminal fittings 10 can be easily manufactured by processing metal plates or the like. Meanwhile, housing 20 can be realized by only a minor modification to the conventional structure, namely, by forming step portions 21 (receiving portion first lower surface 24, receiving portion second lower surface 25), and can be manufactured as easily as conventional housings. Therefore, the above connector 1 can be manufactured at low cost.

[0037] In the above example, the connector 1 (terminal fittings 10) is female, but a similar structure for fixing the terminal fittings to the connector housing can also be used for male types, and similar effects can be obtained in the relationship between the terminal fittings and the connector housing.

[0038] Furthermore, although the above example was for a two-terminal connector as shown in Figure 1, the same applies to connectors with more terminals. In this case, if there are a large number of terminals, it is required that all terminal fittings be securely fixed to the connector housing, so it is particularly effective to use the above configuration for each terminal fitting.

[0039] The present invention has been described above based on an embodiment. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications are possible in the combination of the respective components, and that such modifications are also within the scope of the present invention.
