<Embodiment>
Hereinafter, a connector 1 according to an embodiment of the present invention will be described with reference to the drawings. Hereinafter, for convenience of explanation, in the axial direction (fitting direction) of the connector 1, the side (left side in FIG. 1) to which the mating terminal (not shown) is fitted is the front side, and the opposite side (right side in FIG. 1). Is called the rear side. Further, in FIG. 1, the upper side and the lower side are called the upper side and the lower side, respectively.

As shown in FIG. 2, the connector 1 includes a terminal 10, a housing 20, and a cover 30. Hereinafter, each component that constitutes the connector 1 will be described in order.

First, the terminal 10 will be described with reference to FIGS. In this example, as the terminal 10, the terminal 10A shown in FIG. 3 and the terminal 10B shown in FIG. 4 are used. Both terminals 10A and 10B are female terminals formed by subjecting a plate-shaped metal member to press work, bending work, and the like, and are connected to a connecting portion 11 into which a mating terminal (male terminal, not shown) is fitted. A conductor fixing portion 12 that is continuous to the rear side of the portion 11 and fixes the conductor core of the electric wire W, and a coating fixing portion 13 that is continuous to the rear side of the conductor fixing portion 12 and fixes the coating of the electric wire.

The connecting portion 11 of the terminals 10A and 10B has a rectangular tubular shape, and a pair of projecting portions 14 projecting upward are formed at both ends in the front-rear direction on one side in the width direction of the upper surface. .. Of the pair of protrusions 14, the protrusion 14 on the front side in particular engages with the lance 26 (see FIG. 8) of the housing 20 to fulfill the function of preventing the terminals 10A and 10B from coming off, as will be described later.

As shown in FIG. 3, a pair of press contact blades 15 are formed on the conductor fixing portion 12 of the terminal 10A. By pressing the conductor core wire of the electric wire W against these pressure contact blades 15, the conductor core wire is fixed to the conductor fixing portion 12 and is electrically connected. On the other hand, as shown in FIG. 4, a pair of caulking pieces 15 are formed on the conductor fixing portion 12 of the terminal 10B. By crimping the conductor core wire of the electric wire with these caulking pieces 15, the conductor core wire is fixed to the conductor fixing portion 12 and electrically connected. A pair of caulking pieces 16 is formed on the covering and fixing portion 13 of the terminals 10A and 10B. The electric wire is fixed to the covering fixing portion 13 by crimping the covering of the electric wire with these crimping pieces 16.

The terminal 10B is formed by subjecting the plate-shaped metal member shown in FIG. 5 to press work, bending work, and the like. In FIG. 5, the connecting portion 11 is schematically shown (broken line portion). As can be understood from FIG. 5, a plurality of through holes 17 penetrating in the plate thickness direction are formed in the conductor fixing portion 12 of the terminal 10B. By providing the through holes 17 in this manner, when the conductor core wire is crimped to the conductor fixing portion 12, the conductor core wire enters each of the through holes 17 and adheres closely to the inner wall surface of the through hole 17 when the conductor core wire is crimped. obtain. As a result, the conductor core wire can be firmly fixed to the conductor fixing portion 12. Furthermore, since the contact area between the conductor core wire and the conductor fixing portion 12 increases, the contact resistance between them becomes small.

Next, the housing 20 will be described with reference to FIGS. 6 to 12. In particular, as shown in FIGS. 6 and 9, the housing 20 includes a rectangular flat housing body 21. A plurality of terminal accommodating portions for accommodating the plurality of terminals 10 are formed on the upper and lower surfaces of the housing body 21, respectively. The configurations of the upper surface side and the lower surface side of the housing main body 21 are generally the same, although there are some differences, so only the configuration on the upper surface side of the housing main body 21 will be described below.

On the upper surface of the housing body 21, a plurality of standing walls 22 that extend in the front-rear direction at intervals in the width direction are integrally formed. Each standing wall 22 has a function of partitioning two terminal accommodating portions adjacent to each other in the width direction. That is, on the upper surface of the housing body 21, a plurality of terminal accommodating portions partitioned by the plurality of standing walls 22 are formed so as to be aligned in the width direction.

A top wall portion 23 is integrally formed on the front side portion of the housing body 21 so as to close the upper portion of the terminal accommodating portion. That is, the front side portion of the terminal accommodating portion has a cylindrical shape whose upper portion is closed by the top wall portion 23, and the rear side portion of the terminal accommodating portion is open at the upper portion. An opening 24 is formed at the front end of each terminal accommodating portion (see FIGS. 6 to 8). Through the opening 24, the mating terminal (male terminal) is inserted into the terminal accommodating portion of the housing body 21.

As shown in FIG. 8, a taper surface 25 is formed on the rear edge of the top wall portion 23 so as to be inclined rearward and downward. The tapered surface 25 will be used when the upper cover 30A is assembled to the housing 20 as described later (see FIG. 21). A lance 26 is integrally formed on the lower surface of the central portion of the top wall portion 23 in the front-rear direction so as to project downward into each terminal accommodating portion.

As described above, in the housing body 21, the upper side of the rear side portion of each terminal accommodating portion is open. Therefore, while gripping the terminal 10, as shown in FIGS. 9 and 10, the terminal 10 is placed on the rear side portion of the terminal accommodating portion and pushed forward, so that the terminal 10 is moved forward of the terminal accommodating portion. The side portion (cylindrical portion) can be easily inserted up to the primary locking position (halfway insertion position) in the vicinity of the regular insertion position (see FIGS. 11 and 12).

In the process in which the terminal 10 is inserted to the primary locking position shown in FIGS. 11 and 12, the lance 26 comes into contact with the protrusion 14 on the front side of the terminal 10 so that the protrusion 14 is elastically deformed. After that, the projecting portion 14 passes by and then elastically returns to the initial position. As a result, as shown in FIG. 12, the protrusion 14 engages with the lance 26, so that the function of preventing the terminal 10 from coming off the housing 20 is exerted.

Next, the cover 30 will be described with reference to FIGS. 13 to 22. In this example, as the cover 30, an upper cover 30A and a lower cover 30B are used (see FIG. 2). The upper cover 30A is attached to the upper surface side of the housing main body 21 and has a function of closing the upper portion of the rear side portion of the terminal accommodating portion on the upper surface side, and the lower cover 30B is attached to the lower surface side of the housing main body 21. , And has a function of closing the lower part of the rear side portion of the terminal accommodating portion on the lower surface side.

First, the upper cover 30A will be described with reference to FIGS. FIG. 13 shows the upper cover 30A facing the housing main body 21, and FIG. 14 shows the upper cover 30A turned upside down.

The upper cover 30A includes a flat plate-shaped cover body 31. Corresponding to the standing walls 22 of the housing body 21, a plurality of standing walls 32 that extend in the front-rear direction at intervals in the width direction are integrally formed on the lower surface of the front side portion of the cover body 31. As a result, when the upper cover 30A is assembled to the housing 20, the upper side of the rear side portion of the terminal accommodating portion of the housing main body 21 is closed by the upper cover 30A, and the front side portion and the rear side portion of the terminal accommodating portion are closed. , A terminal accommodating portion having a cylindrical shape continuous in the front-rear direction is configured.

A taper surface 33 is formed on the front end edge of the cover body 31 of the upper cover 30A so as to be inclined forward and upward. The taper surface 33 will be used when the upper cover 30A is assembled to the housing 20 as described later (see FIG. 21).

On the lower surface of the front end portion of the cover body 31 of the upper cover 30A, as shown in FIG. 15, a plurality of protrusions 34 projecting downward are provided at positions of the plurality of terminal accommodating portions in the width direction (between adjacent standing walls 32). Position) is integrally formed. As will be described later, the protrusion 34 has a function of pushing the terminal 10 at the primary locking position forward to move the terminal 10 to the regular insertion position when the upper cover 30A is assembled to the housing 20.

The rear side portion of the cover body 31 of the upper cover 30A projects rearward from the rear end surface of the housing 20 when the upper cover 30A is assembled to the housing 20. The rear side portion 37 of the cover body 31 cooperates with the rear side portion 37 (see FIGS. 16 and 17) of the cover body 31 of the lower cover 30B so that the plurality of terminals 10 accommodated in the plurality of terminal accommodating portions are separated from each other. It functions as a so-called connector cover that houses and protects the plurality of electric wires W extending to the rear side.

Engaging portions 36 of the lower cover 30B (see FIGS. 16 and 17) at a plurality of locations (four locations in this example) on both ends in the width direction of the cover body 31 of the upper cover 30A when assembled to the housing 20. Engagement portions 35 that respectively engage with are integrally formed (see FIG. 20).

Next, the lower cover 30B will be described with reference to FIGS. FIG. 16 shows the lower cover 30B facing the housing body 21, and FIG. 17 shows the inverted lower cover 30B. The configurations of the upper cover 30A and the lower cover 30B are generally the same, although there are some differences except that they are symmetrical in the vertical direction. Therefore, regarding the lower cover 30B, the same reference numerals as those of the upper cover 30A are given to the configurations corresponding to the respective configurations of the upper cover 30A, and the description thereof is replaced.

Regarding the lower cover 30B, as shown in FIGS. 16 and 17, a wire holding portion 38 is integrally formed on the rear side (rear side end portion) of the rear side portion 37 functioning as a connector cover. .. The electric wire holding portion 38 is a portion used for bundling and holding a plurality of electric wires W extending rearward from the housing 20. The plurality of electric wires W extending from the housing 20 to the rear side are held by the electric wire holding portion 38 in a bundled state using a tie band or the like. The wire holding portion 38 will be described in detail later.

As shown in FIGS. 19 to 22, when the upper cover 30A and the lower cover 30B are assembled to the housing 20, the taper surface 33 of the front end edge of the upper cover 30A is located behind the top wall portion 23 on the upper surface side of the housing 20. The front end edge of the upper cover 30A and the rear end edge of the top wall portion 23 on the upper surface side of the housing 20 are engaged with each other in a state where the taper surface 25 of the end edge is inserted (see FIG. 21). With the tapered surface 33 of the front edge of the lower cover 30B entering the upper side of the tapered surface 25 of the rear edge of the top wall portion 23 on the lower surface side of the housing 20, the front edge of the lower cover 30B and the lower surface side of the housing 20 are provided. The rear edge of the top wall portion 23 is locked (see FIG. 22). Further, the plurality of engaging portions 35 of the upper cover 30A and the plurality of engaging portions 36 of the lower cover 30B are locked to each other (see FIG. 20). By these cooperations, the upper cover 30A and the lower cover 30B are respectively immovably assembled to the housing 20, and the upper cover 30A and the lower cover 30B are also immovably assembled to each other.

Next, the procedure for assembling the connector 1 will be described with reference to FIGS. First, as shown in FIG. 23, a predetermined device is used in a rear side portion of the predetermined upper surface (the lower surface in the normal orientation) of the housing 20 which is turned upside down and the upper side of which is open. The terminals 10A are respectively arranged, and a predetermined portion of the terminal 10A (typically, the rear end surface of the rectangular tube-shaped connecting portion 11) is moved forward to the primary locking position shown in FIGS. 11 and 12 described above. Push in. As a result, the protrusion 14 of the terminal 10A is engaged with the lance 26 of the housing 20, so that the terminal 10A inserted into the terminal accommodating portion is prevented from coming off the housing 20.

Next, as shown in FIG. 24, the electric wire W is connected to each terminal 10A inserted into the terminal accommodating portion by using a predetermined device. Specifically, the conductor core wire of the electric wire W is pressed against the pair of press contact blades 15 of the terminal 10A, and the covering of the electric wire W is crimped by the pair of caulking pieces 16 of the terminal 10A.

Next, as shown in FIG. 25, the housing 20 is turned upside down. As a result, the orientation of the housing 20 becomes the regular orientation. In this state, similarly to the procedure shown in FIGS. 23 and 24, as shown in FIGS. 26 and 27, the terminal 10A is placed in the predetermined terminal accommodating portion on the upper surface side of the housing 20 up to the primary locking position. Each is inserted, and the electric wire W is connected to each inserted terminal 10A.

Next, as shown in FIG. 28, the terminal 10B in a state in which the electric wire W is preliminarily connected to the predetermined terminal accommodating portion on the upper surface side or the lower surface side of the housing 20 in which the terminal 10A is not yet inserted is predetermined. Using the device, insert each to the primary locking position. Note that this work may be performed manually by the worker.

Next, as shown in FIG. 29, the lower cover 30B is assembled to the housing 20, and then the upper cover 30A is assembled to the housing 20 as shown in FIG. The procedure for assembling the upper cover 30A and the lower cover 30B to the housing 20 is generally the same except that they are vertically symmetrical. Therefore, hereinafter, only the procedure for assembling the upper cover 30A to the housing 20 will be described with reference to FIGS. 31 to 35.

As shown in FIGS. 31 and 32, with the terminal 10 inserted in the terminal accommodating portion in the primary locking position, first, as shown in FIG. 33, the rear side of the upper cover 30A is higher than the front side. While maintaining the inclined state, the front end edge of the upper cover 30A (cover body 31) is brought closer to the rear end edge of the top wall portion 23 of the housing 20, and as shown in FIG. The portion 34 is brought into contact with the rear end of the connecting portion 11 of the terminal 10.

Next, while maintaining this state (that is, the state in which the upper cover 30A is inclined and the protruding portion 34 is in contact with the connecting portion 11 of the terminal 10), the taper surface 33 of the front end edge of the upper cover 30A is raised. The upper cover 30A is attached to the housing 20 until it enters below the tapered surface 25 of the rear end edge of the wall portion 23 (until the front end edge of the upper cover 30A and the rear end edge of the top wall portion 23 engage). At this time, the terminal 10 moves from the primary locking position to the regular insertion position as the upper cover 30A moves to the front side by pressing the protrusion 34.

Next, while maintaining the state in which the front edge of the upper cover 30A and the rear edge of the top wall portion 23 are engaged, the inclined upper cover 30A is set with the tip side of the upper cover 30A as a fulcrum, As shown in FIG. 35, the rear side of the upper cover 30A is rotated so as to approach the housing 20. As a result, the plurality of engaging portions 35 of the upper cover 30A and the plurality of engaging portions 36 of the lower cover 30B are locked to each other, so that as shown in FIG. A state in which 30A and the lower cover 30B are assembled is obtained. Then, finally, the plurality of electric wires W extending rearward from the housing 20 are held in the electric wire holding portion 38 in a state of being bundled by using a tie band or the like. This completes the assembly of the connector 1.

As shown in FIG. 35, when the upper cover 30A is assembled to the housing 20, the protrusion 34 of the upper cover 30A is in face-to-face contact with or close to the rear end surface of the connecting portion 11 of the terminal 10. Therefore, the function of preventing the terminal 10 from coming off the housing 20 is exerted. That is, in addition to the engagement of the protrusion 14 and the lance 26 of the terminal 10, the so-called double-locked state is obtained by the engagement of the connecting portion 11 and the protrusion 34 of the terminal 10.

As described above, the upper cover 30A is attached to the housing 20 in a normal state only by rotating the inclined upper cover 30A with the tip end side of the upper cover 30A as a fulcrum. Is designed. Even if an attempt is made to move the upper cover 30A in parallel with the housing 20 from the upper side to the lower side while assembling the upper cover 30A to the housing 20, the front end edge of the upper cover 30A and the rear of the top wall portion 23 may be removed. It cannot be assembled due to interference with the edge.

Hereinafter, with reference to FIGS. 36 to 39, the wire holding portion 38 integrally provided on the lower cover 30B will be described. As shown in FIG. 39, the electric wire W includes a conductor core wire W1 and a coating W2 that covers the conductor core wire W1.

As shown in FIGS. 36 to 38, the electric wire holding portion 38 of the present example has a rectangular flat plate-like electric wire binding portion 38a that integrally extends rearward from the rear side end portion of the rear side portion 37 of the lower cover 30B. . The electric wire binding portion 38a is used to bundle a plurality of electric wires W using a tie band. That is, the plurality of electric wires W extending rearward from the housing 20 are arranged along the upper and lower surfaces of the electric wire binding portion 38a, and the tie band is wound around the electric wire binding portion 38a and the plurality of electric wires W. As a result, the plurality of electric wires W extending rearward are held in the electric wire binding portion 38a in a bundled state.

On each of the upper and lower surfaces of the electric wire binding portion 38a (that is, the contact surface with which the coating W2 of the electric wire W comes into contact), a plurality of protrusions 39 are provided along the width direction (that is, the direction intersecting with the extending direction of the electric wire W). Is formed (see FIG. 38). Further, on the upper and lower surfaces (contact surfaces) of the portions 38b and 38c located on the rear side and the front side of the electric wire binding portion 38a, which come into contact with the electric wire W while holding the plurality of electric wires W in the electric wire binding portion 38a. Also, a plurality of ridges 39 are formed along the width direction (see FIG. 38).

Therefore, when a plurality of electric wires W are bundled and held in the electric wire binding portion 38a by using a tie band, the coating W2 of the electric wire W contacting the contact surface of the electric wire binding portion 38a bites into the plurality of protrusions 39. (See FIG. 39). Further, the coating W2 of the electric wire W, which is in contact with the contact surfaces of the portions 38b and 38c, bites into the plurality of ridges 39. Thereby, even if the diameter of the electric wires W is reduced and the number of the electric wires W is increased, the electric wire holding force of the electric wire holding portion 38 can be improved.

Furthermore, since the plurality of ridges 39 are provided along the width direction (that is, the direction intersecting the extending direction of the electric wire W), when the electric wire W is pulled in the extending direction (rearward) by an external force or the like, Also, the relative movement of the electric wire W with respect to the electric wire holding portion 38 can be suppressed as much as possible.
