TECHNICAL FIELD
[0001] The present disclosure relates to a terminal cover. BACKGROUND
[0002] The terminal cover of the present disclosure is used for the purpose of protecting a terminal connection portion of a machine such as a battery, an alternator, a starter, and the like, which is mainly mounted on a vehicle. Generally, such a terminal cover is not installed after the terminal bolt is tightened to the vehicle-mounted machine in the assembly process of the vehicle, but is manufactured at the manufacturer of the wire harness in a state in which the terminal cover is inserted through the terminal-attached electric wire, and is incorporated into the assembly line of the vehicle. Also, in the connection process in which the terminal is connected to the vehicle-mounted machine, a portion of the terminal cover is opened to expose the connection portion of the terminal, and after the terminal bolt and the nut are tightened, the terminal cover is closed to protect the terminal. In order to further smoothly perform the above-described connection process, it is desirable that the terminal-attached electric wire with the terminal cover installed thereon is temporarily stopped in a state in which the terminal cover exposes the connection portion of the terminal, and is transported to the assembly line of the vehicle.
[0003] In the past, as an example of such a terminal cover, a terminal cover described in Japanese Patent Application Publication No. 8-96863 (Patent Literature 1) is known. The terminal cover has a cover portion composed of a cover main body that houses an electric wire and is installed on a terminal post side, and a protection opening and closing body that is coupled to the cover portion via a hinge. A temporary stopping protrusion is provided on the cover portion, and a stopping hole that engages with the temporary stopping protrusion is provided on the protection opening and closing body. The protection opening and closing body is temporarily stopped on the cover portion in an open state.

Therefore, for example, when the terminal-attached electric wire with the terminal cover installed thereon is transported, it is possible that the temporary stopping is released by an external force, and thus the open state is released.
[0009] The present disclosure is completed based on the above-described situation, with the aim of providing a terminal cover in which the open state is difficult to release by an external force.
[0010] SOLUTION TO THE PROBLEM
[0011] The terminal cover disclosed herein comprises: a terminal protection body having an opening at the top; a wire protection portion disposed continuously rearward from the terminal protection body; and a cover body that is hinged to the front end of the wire protection portion and is capable of opening and closing the opening from the top. A locking wall is provided extending upward from the upper surface of the wire protection portion, the locking wall having a locking protrusion. The cover body has a protrusion and a surrounding portion. In a closed state where the opening is closed, the protrusion protrudes upward from the upper surface of the wire protection portion, the surrounding portion is disposed continuously downward from the protrusion and expands outward from the protrusion, a locking portion is provided on the protrusion, the locking wall abuts against the protrusion, and the locking protrusion and the locking portion lock together, thereby keeping the cover body in an open state where the opening is open. In the open state, the locking wall covers the opening so that the locking portion is not exposed to the outside, and the surrounding portion covers the opening so that the locking protrusion is not exposed to the outside.

[0035] [Details of Embodiments of the Present Disclosure]
[0036] Embodiments of the present disclosure are described below. The present disclosure is not limited to these examples, but is shown by the claims, and it is intended to include all modifications within the meaning and range equivalent to the claims.
[0037] [Embodiments]
[0038] While referring to Figures 1 to 9 Embodiments of the present disclosure are described.
[0039] [Terminal Cover]
[0040] The terminal cover 1 of the present embodiment is composed of an insulating synthetic resin. As shown in Figure 2 , the terminal cover 1 is used as a protection member that fastens the terminal 2 to the fastening portion of the terminal post 3 using a fastening member 4 such as a nut. As shown in Figure 1 and Figure 2 , the terminal cover 1 has a terminal protection body 10 having an opening portion 11, a wire protection portion 20 provided continuously with the terminal protection body 10, and a cover 30 that can open and close the opening portion 11. In the following description, the length direction of the terminal cover 1 is taken as the front-rear direction, the wire protection portion 20 is disposed behind the terminal protection body 10, and the opening portion 11 of the terminal protection body 10 is open upward.
[0041] [Terminal Protection Body, Opening Portion]
[0042] As shown in Figure 2As shown, the terminal protection body 10 has a cylindrical peripheral wall 12 that opens vertically. The upper opening of the peripheral wall 12 of the terminal protection body 10 is formed by an opening portion 11. Figure 1 As shown, the opening 11 is closed by a dome-shaped cover 30. Thus, the opening 11 is closed when it is sealed by the cover 30. In the closed state, as... Figure 3 As shown, a pair of locking tabs 13 disposed on the peripheral wall 12 of the terminal protection body 10 and a pair of locking protrusions 31 disposed on the cover 30 are engaged. The lower opening of the peripheral wall 12 of the terminal protection body 10 can receive the terminal post 3.
[0043] [Electrical cable protection section, locking wall, locking protrusion, third cone surface]
[0044] The wire protection section 20 is cylindrical and open in the front-to-back direction. The wire protection section 20 is connected via... Figure 4 The hinge 20H shown serves as a pivot, allowing the upper wire protection part 20U to rotate relative to the lower wire protection part 20L, and causing... Figure 1 and Figure 4 The locking protrusion 20A and locking arm 20B shown are engaged to form a locking mechanism. Figure 4 As shown, the wire protection section 20 has a pair of left and right side walls 28 and a top wall 29 connecting the upper ends of the side walls 28 to each other. Figure 1 As shown, a pair of locking walls 22 are provided extending upwards on the front half of the upper surface 21 of the wire protection section 20. The pair of locking walls 22 are located at the left and right ends of the top wall 29 of the wire protection section 20. Figure 4 As shown, each locking wall 22 is arranged opposite and parallel to each other by having a pair of side walls 28 protrude above the upper surface 21 of the top wall 29. Figure 1 and Figure 4 As shown, a pair of locking protrusions 23 are provided on the inner surfaces of a pair of locking walls 22. The locking protrusions 23 are formed protruding in a left-right direction (the direction in which the pair of locking walls 22 are opposite to each other). Figure 6 As shown, a third conical surface 24 is provided at the rear end of the locking protrusion 23. The third conical surface 24 is inclined in such a way that it gets closer to the locking wall 22 as it moves towards the rear.
[0045] [Hinge, First Conical Surface]
[0046] like Figure 9 As shown, a release auxiliary wall 25 is provided protruding upward from the front end of the top wall 29 of the wire protection section 20. The release auxiliary wall 25 is connected to the cover 30 by a flexible hinge 26. A first conical surface 27 is provided on the upper side of the release auxiliary wall 25. The first conical surface 27 is inclined in a manner that the higher it is, the more it is inclined forward.
[0047] [Cover, protrusion, surrounding part, second conical surface]
[0048] like Figure 1 As shown, the cover 30 can rotate about the hinge 26 and remain in a closed state. Figure 1 ) and the open state of the opening 11 ( Figure 2 The cover 30 has a protrusion 32 and a surrounding portion 33. In the closed state, the protrusion 32 protrudes upward above the upper surface 21 of the wire protection portion 20, and the surrounding portion 33 is continuously provided downward below the protrusion 32. The protrusion 32 forms the upper part of the cover 30 and has a peripheral wall 32A. Figure 3 As shown, the surrounding portion 33 is formed to expand outward from the peripheral wall 32A. (As indicated...) Figure 9 As shown, in the open state, a second conical surface 36 is provided at the front end of the protrusion 32. The second conical surface 36 is inclined in a manner that the higher it is, the more it is inclined forward.
[0049] [Locking part, fourth cone surface]
[0050] like Figure 7 As shown, a thin-walled portion 34, a portion of the peripheral wall 32A, is formed in the protrusion 32. (As shown...) Figure 4 As shown, in the open state, a pair of thin-walled portions 34 are arranged opposite to a pair of locking walls 22. Figure 8 As shown, in the open state, a locking portion 35 is provided in the front half of the thin-walled portion 34. Figure 5 As shown, in the open state, the protrusion 32 is embedded between a pair of retaining walls 22, and the peripheral wall 32A and the pair of retaining walls 22 abut against each other in the left-right direction. Additionally, as... Figure 4 and Figure 8 As shown, the locking part 35 locks into the locking protrusion 23 from below. Figure 8 As shown, in the open state, a fourth conical surface 37 is provided on the rear half of the thin-walled portion 34. The fourth conical surface 37 is recessed from the locking portion 35. The fourth conical surface 37 is inclined such that the peripheral wall 32A of the protrusion 32 becomes thicker towards the lower surface. The upper edge of the fourth conical surface 37 is connected to the thin-walled portion 34 at the same height as the locking portion 35.
[0051] In the above structure, in the open state, such as Figure 4 As shown, the locking wall 22 covers the locking portion 35 so that it is not exposed to the outside. Additionally, the surrounding portion 33 covers the locking protrusion 23 so that it is not exposed to the outside. That is, in the open state, neither the locking portion 35 nor the locking protrusion 23 is exposed to the outside. Therefore, external forces are difficult to directly apply to the locking portion 35 and the locking protrusion 23. Thus, for example, during transport, it is difficult to disengage the locking portion 35 and the locking protrusion 23 by external force, and the open state can be stably maintained.
[0052] Further, in the above-described structure, by sliding the lid 30 in the open state to the front, the manual release of the open state becomes easy as described below. Further, the length of the hinge 26 in the front-rear direction in the closed state is set to a degree that allows the lid 30 to slide to the front with a margin.
[0053] When the lid 30 in the open state is moved to the front, the lid 30 is pressed to the front and also moved upward by the engagement of the first taper 27 and the second taper 36, and thus the open state is easily released. Figure 6 In this case, the lid 30 is pressed to the front and also moved upward by the engagement of the first taper 27 and the second taper 36, and thus the open state is easily released.
[0054] Further, when the lid 30 in the open state is slid to the front, the lid 30 is pressed to the front and also moved upward by the engagement of the first taper 27 and the second taper 36, and thus the open state is easily released. Figure 9 In this case, the lid 30 is pressed to the front and also moved upward by the engagement of the first taper 27 and the second taper 36, and thus the open state is easily released.
[0055] Further, when the lid 30 in the open state is moved to the front and upward, the locking protrusion 23 engages with the fourth taper 37, and easily crosses the upper wall 32A. Thus, the open state is also easily released. Figure 8 In this case, the lid 30 is pressed to the front and also moved upward by the engagement of the first taper 27 and the second taper 36, and thus the open state is easily released.
