[0029] Reference Figure 1 to Figure 6 A “connector” according to a first embodiment of the present invention will be described.

[0030] Figure 1 to Figure 3 The connector 1 shown in the figure comprises: a connector body 2 which houses a terminal connected to the end of an electric wire; a first cover 3 which is assembled to the rear end side of the connector body 2; and a second cover 4 which positions the electric wire led out from the rear end of the connector body 2 between the second cover 4 and the first cover 3. Figure 1 to Figure 3 In the figure, the electric wires and the terminals are not shown. The connector 1 is mated with a counterpart connector (not shown).

[0031] In this specification, for connector 1, the other connector side in the mating direction with the other connector is defined as "front", and the side away from the other connector in the mating direction is defined as "rear". In addition, the up-down and left-right directions of connector 1 mentioned in this specification are based on the paper direction of the drawings, which are expressed for the convenience of explanation and may not be consistent with the actual direction of connector 1 in the use state.

[0032] The connector body 2 is made of insulating synthetic resin and includes a housing body 20 that accommodates the plurality of terminals, a hood 21 that surrounds the housing body 20 , and a lock arm 22 .

[0033] When the connector 1 is mated with the mating connector, the housing of the mating connector is inserted between the housing body 20 and the cover 21 , and the terminals of the mating connector are inserted into the housing body 20 , so that the terminals of the connector 1 are electrically connected to the terminals of the mating connector.

[0034] The lock arm 22 is disposed above the housing body 20. The lock arm 22 is locked with the mating connector to maintain the mating state of the connector 1 and the mating connector.

[0035] A pair of ribs 23 extending in the up-down direction are formed at the rear end and the left and right side surfaces of the cover portion 21. The pair of ribs 23 are portions for assembling the first cover 3.

[0036] The first cover 3 and the second cover 4 are made of insulating synthetic resin. The first cover 3 and the second cover 4 are assembled to form a wire wiring path 5, which is a wiring path for a plurality of wires led out from the rear end of the connector body 2. The wire wiring path 5 is formed in an L-shape extending backward from the rear end of the connector body 2 and bending upward in the middle.

[0037] like Figure 3 As shown, the first cover 3 is slid from the upper direction of the connector body 2 in the direction of the arrow D1 and assembled to the connector body 2. After the first cover 3 is assembled to the connector body 2, as shown in FIG. Figure 3 As shown, the second cover 4 is slid from the rear of the first cover 3 in the direction of arrow D2 and assembled to the first cover 3 .

[0038] like Figure 1 , Figure 5 As shown, the first cover 3 includes: a pair of side plates 31 for positioning the rear half of the cover 21 between each other; a wiring path forming portion 32 for connecting the rear ends of the pair of side plates 31 to each other; a pair of locking arms 34; and a pair of protective side walls 35.

[0039] A groove 33 is formed on the inner surface of the pair of side plates 31 to engage with the ribs 23. Figure 3 As shown, when the first cover 3 slides from above the connector body 2 in the direction of arrow D1 , the grooves 33 of the pair of side plates 31 engage with the pair of ribs 23 of the connector body 2 , whereby the first cover 3 is assembled to the connector body 2 .

[0040] The wiring path forming portion 32 has a concave portion with a semicircular cross section extending in the up-down direction. The wiring path forming portion 32 is combined with the wiring path forming portions 41 and 42 of the second cover 4 to form the above-mentioned L-shaped wire wiring path 5.

[0041] The pair of locking arms 34 are portions that are locked to the pair of locking portions 44 of the second cover 4. The pair of locking arms 34 respectively include arm portions 34a extending in parallel to each other from the rear ends of the pair of side plate portions 31 toward the rear (i.e., from the connector body 2 side toward the second cover 4 side) and protrusions 34b protruding toward directions approaching each other from the ends of the arm portions 34a.

[0042] A pair of protective side walls 35 extend rearward from the rear ends of the pair of side plate portions 31 and are disposed outside the pair of arm portions 34a. A gap is provided between each protective side wall 35 and each arm portion 34a. The gap is a gap (space) for allowing the arm portion 34a to bend outward when the locking arm 34 is locked with the locking portion 44.

[0043] like Figure 2 , Figure 4 , Figure 5 As shown, the second cover 4 has wiring path forming parts 41 and 42. The wiring path forming part 41 extends rearward from the vicinity of the rear end of the connector body 2 and is arranged below the above-mentioned wiring path forming part 32. The wiring path forming part 41 is arranged with a gap between it and the wiring path forming part 32 for allowing the wires to pass through. The wiring path forming part 42 is connected to the rear end of the wiring path forming part 41 and extends upward. The wiring path forming part 42 has a recessed portion with a semicircular cross-section. The wiring path forming part 42 is arranged opposite to the above-mentioned wiring path forming part 32, and the recessed portion of the wiring path forming part 42 and the recessed portion of the wiring path forming part 32 constitute a wire wiring path with a circular cross-section. In this way, the wiring path forming part 32, the wiring path forming part 41, and the wiring path forming part 42 are combined to form the above-mentioned L-shaped wire wiring path 5.

[0044] The second cover 4 also has a pair of protective inner walls 43, a pair of stopper parts 44, a pair of protective side walls 45, a pair of protective upper walls 46, a pair of protective lower walls 47 and a pair of protective rear walls 48. The pair of protective inner walls 43 are arranged on the left and right sides of the wiring path forming part 42. As described above, the pair of stopper parts 44 are the parts where the pair of stopper arms 34 are stopped. The pair of stopper parts 44 are respectively connected to the pair of protective inner walls 43 and protrude in the direction of separation from each other. The pair of protective side walls 45 are arranged on the outer side of the pair of stopper arms 34 and on the opposite side of the protrusion 34b. Each protective side wall 45 is adjacent to each protective side wall 35 of the first cover 3. The pair of protective upper walls 46 are arranged above the pair of stopper arms 34. The pair of protective lower walls 47 are arranged below the pair of stopper arms 34. The pair of protective rear walls 48 are arranged behind the pair of stopper arms 34.

[0045] like Figure 3As shown, when the second cover 4 slides in the direction of arrow D2 from the rear of the first cover 3, the pair of locking arms 34 and the pair of locking portions 44 are respectively locked, thereby being assembled to the first cover 3. In addition, when the locking arms 34 are locked with the locking portions 44, the protrusions 34b go over the locking portions 44, so that the arm portions 34a are bent outward, and the protrusions 34b go over the locking portions 44, so that the bent arm portions 34a are restored to form Figure 5 The locked state is shown.

[0046] like Figure 5 As shown, the side plate portion 31 is arranged in front of the locking arm 34 in the locked state with the locking portion 44. A protective rear wall 48 is arranged behind the locking arm 34. A protective upper wall 46 is arranged above the locking arm 34. A protective lower wall 47 is arranged below the locking arm 34. Protective side walls 35 and 45 are arranged outside the locking arm 34. A protective inner wall 43 is arranged inside the locking arm 34.

[0047] In this way, the first cover 3 and the second cover 4 cover all directions around the locking arm 34 in the locked state with the locking portion 44 by the side plate portion 31, the protective rear wall 48, the protective upper wall 46, the protective lower wall 47, the protective side walls 35, 45, and the protective inner wall 43. These side plate portion 31, the protective rear wall 48, the protective upper wall 46, the protective lower wall 47, the protective side wall 35, the protective side wall 45, and the protective inner wall 43 are equivalent to the "protection portion" in the claims.

[0048] like Figure 1 , Figure 2 , Figure 6 As shown in FIG. 1 , a jig insertion opening 40 is formed in the pair of protective side walls 45 to expose a portion of the locking arm 34. In this example, only the tip of the arm portion 34a is exposed through the jig insertion opening 40. The jig insertion opening 40 is a small opening for inserting a rod-shaped jig 9. When the first cover 3 and the second cover 4 assembled together are to be disassembled, the jig 9 is inserted into the jig insertion opening 40 and then removed. Figure 6 By operating in the direction of arrow D3 in FIG. 3 , the arm portion 34 a can be bent outward, and the first cover 3 and the second cover 4 can be separated.

[0049] As described above, in the connector 1, the side plate portion 31, the protective rear wall 48, the protective upper wall 46, the protective lower wall 47, the protective side walls 35, 45, and the protective inner wall 43 cover all directions around the locking arm 34 in the locked state with the locking portion 44. Thus, no matter from which direction an undesirable load is applied, the first cover 3 and the second cover 4 can be prevented from being separated. In addition, when the first cover 3 and the second cover 4 are to be disassembled, the first cover 3 and the second cover 4 can be separated by inserting the jig 9 into the jig insertion opening 40. In addition, the jig insertion opening 40 is a small opening that exposes only a part of the locking arm 34, so even if the peripheral parts of the connector 1 hit the jig insertion opening 40, the peripheral parts will not directly contact the locking arm 34, and the locked state of the locking arm 34 can be maintained.

[0050] Reference Figure 7 to Figure 10 A “connector” according to a second embodiment of the present invention will be described. Figure 7 to Figure 10 In the present invention, the same components as those in the first embodiment are denoted by the same reference numerals and their description is omitted.

[0051] Figure 7 , Figure 8 , Fig.10 The connector 101 shown in the figure comprises: a connector body 2 which houses a terminal connected to the end of an electric wire; a first cover 3 which is assembled to the rear end side of the connector body 2; and a second cover 104 which positions the electric wire led out from the rear end of the connector body 2 between the second cover 104 and the first cover 3. Figure 7 , 8 In the embodiment 10 and 10, the electric wires and the terminals are not shown. That is, the connector 101 has the same structure as the connector 1 of the first embodiment except for the second cover 104.

[0052] The second cover 4 of the first embodiment has a jig insertion opening 40 formed in a pair of protective side walls 45, but the second cover 104 of this example is Figure 7 to Figure 9 As shown, a pair of protective upper walls 46 disposed above a pair of locking arms 34 are formed with jig insertion openings 140. In addition, the pair of jig insertion openings 140 are disposed on both sides of the wire lead-out port in the wire wiring path 5. In this example, only the distal end of the locking arm 34 is exposed through the jig insertion openings 140. The jig insertion openings 140 are small openings for inserting a rod-shaped jig 9.

[0053] When the first cover 3 and the second cover 104 assembled to each other are to be disassembled, Figure 7 As shown, by inserting the jig 9 into the jig insertion opening 140 and operating it, the arm portion 34 a can be bent outward, and the first cover 3 and the second cover 104 can be separated.

[0054] The connector 101 of this example is similar to the connector 1 of the first embodiment, and all directions around the locking arm 34 in the locked state with the locking portion 44 are covered by the side plate portion 31, the protective rear wall 48, the protective upper wall 46, the protective lower wall 47, the protective side walls 35 and 45, and the protective inner wall 43. Therefore, no matter from which direction an undesirable load is applied, the first cover 3 and the second cover 104 can be prevented from being separated. In addition, when the first cover 3 and the second cover 104 are to be disassembled, the first cover 3 and the second cover 104 can be separated by inserting the jig 9 into the jig insertion opening 140. In addition, the jig insertion opening 140 is a small opening that only exposes a part of the locking arm 34. Therefore, even if the peripheral parts of the connector 101 contact the jig insertion opening 140, the peripheral parts will not directly contact the locking arm 34, and the locked state of the locking arm 34 can be maintained.

[0055] In the above embodiment, the first cover 3 has the locking arm 34 and the second cover 4, 104 has the locking portion 44, but in the present invention, the second cover may have the locking arm and the first cover may have the locking portion.

[0056] In the above-described embodiment, the jig insertion openings 40 and 140 are formed in the protection portion on the second cover 4 and 104 side. However, in the present invention, the jig insertion openings may be formed in the protection portion on the first cover side.

[0057] In addition, the above-mentioned embodiment is only a representative mode of the present invention, and the present invention is not limited to the embodiment. That is, various deformations can be carried out within the scope of the gist of the present invention. Even if such deformation is carried out, as long as the structure of the present invention is provided, it is certainly also included in the scope of the present invention.
