The second connecting portion 240 may be recessed from the second body portion 230 in the insertion direction of the first connecting portion 150 to accommodate the first connecting portion 150.

[0086] 2nd connection part 240 may include a second high-voltage connector 241 and a second low-voltage connector 242. The second high-voltage connector 241 and the second low-voltage connector 242 may have a recessed shape from the second body part 230 in a shape corresponding to the first high-voltage connector 151 and the first low-voltage connector 152, respectively.

[0087] The second connecting part 240 may have an inclined part 250 formed at an edge thereof, on which the first connecting part 150 is inclined so as to be slidable. The inclined portion 250 is inclined relative to the insertion direction (or the coupling axis Z-Z') in a direction away from the coupling axis Z-Z' in the insertion direction. 240 The edge of the

[0088] The second high-voltage connector 241 and the second low-voltage connector 242 may be provided inside the inclined portion 250 when viewed along the insertion direction (or the coupling axis ZZ').

[0089] 22 is a conceptual diagram showing the sliding of the first connector and the second connector according to one embodiment of the present invention. The explanations regarding the above-mentioned embodiment can be applied in the same or similar manner to this embodiment.

[0090] When the second connector 20 is attached to the first connector 10, it can be attached by the weight of the battery module assembly 3 described above. When the second connector 20 is attached to the first connector 10 due to the weight of the battery module assembly 3 in a temporary mounting state, the first connecting portion 150 of the first connector 10 can be accurately inserted into the second connecting portion 240 of the second connector 20 without colliding with or coming into contact with it.

[0091] When the second connector 20 is attached to the first connector 10 due to the weight of the battery module assembly 3 in a temporary attachment state, the first connecting portion 150 of the first connector 10 may collide with or come into contact with the second connecting portion 240 of the second connector 20. In this case, the first connecting portion 150 may collide with or come into contact with the inclined portion 250.

[0092] The inclination of the inclined portion 250 of the first connecting part 150 can guide the insertion into the inside of the second connector 20. For example, when viewed from above along the coupling axis Z-Z', the first connecting part 150 can contact the left upper end LH, the right upper end RH, the left lower end LL, and the right lower end RL. Since the left upper end LH, the right upper end RH, the left lower end LL, and the right lower end RL are formed with inclined surfaces, No. 1 The connecting portion 150 can be guided inside the second connector 20 .

[0093] In the above description, the left upper end LH, the right upper end RH, the left lower end LL, and the right lower end RL are used as examples, but the present invention can be applied to any point on the inclined portion 250 in the same manner.

[0094] The first connecting part 150 has rounded parts 151-1 and 152-1, which are more effective than the inclined part 250 and can guide the insertion while minimizing damage and wear.

[0095] Fig. 23 is a perspective view showing a state in which a holding member is attached to a first connector housing according to an embodiment of the present invention, Fig. 24 is a conceptual diagram showing a state in which a holding member is attached to a first connector housing according to an embodiment of the present invention, and Fig. 25 is a partially enlarged view showing a state in which a holding member is attached to a first connector housing according to an embodiment of the present invention. The explanations regarding the above-mentioned embodiments can be applied equally or similarly to this embodiment.

[0096] The first connector 10 may include a retaining member 170 . The retaining member 170 can be attached to the first body portion 130 so that the first connector 10 can move within a predetermined range. For example, the retaining member 170 can be attached to the first body portion 130 so that the first connector 10 can move within a predetermined range when the second connector 20 is attached to the first connector 10. Specifically, the retaining member 170 can be attached to the retaining member attachment portion of the first body portion 130. 131 can be attached to.

[0097] The holding member 170 can movably couple the first body portion 130 to the battery module assembly 3 (or the first connector mounting portion 3-1) to which the first body portion 130 is attached.

[0098] The first body portion 130 may be provided with a holding member mounting portion 131 having a through hole formed therein so that the holding member 170 can be mounted thereto. The through hole formed in the holding member mounting portion 131 may have a shape including a hemispherical shape. The hemispherical shape allows the distance between the first portion 172 of the holding member 170 and the holding member mounting portion 131 to be a constant distance.

[0099] A portion of the holding member 170 is in contact with the holding member attachment portion 131 , and another portion is spaced apart from the holding member attachment portion 131 . The holding member 170 may include a head portion 171. For example, the head portion 171 may be a portion that has a diameter larger than the through-hole and is placed on the holding member attachment portion 131.

[0100] The holding member 170 may include a first portion 172. For example, the first portion 172 may be connected to the head portion 171 and spaced a predetermined distance L5 from the holding member mounting portion 131. The first portion 172 may have a length corresponding to the thickness of the first body portion 130.

[0101] The holding member 170 may include a second portion 173. For example, the second portion 173 may be connected to the first portion 172 and have a smaller outer diameter than the first portion 172. However, the second portion 173 does not necessarily have to have a smaller outer diameter than the first portion 172, and is not particularly limited. The second portion 173 can be coupled to the battery module assembly 3 (or the first connector mounting portion 3-1).

[0102] When the second connector 20 is attached to the first connector 10, if the first connector 10 is able to move within a predetermined range, damage and wear can be minimized and the attachment of the second connector 20 can be guided onto the first connector 10. In other words, since the first connector 10 is free to move by a certain distance L5, No. 1 The connecting portion 150 can be effectively guided inside the second connector 20 .

[0105] The first high-voltage terminal block 111 may include a second block 320. For example, the second block 320 may be provided to be coupled to the first block 310 and may surround the other side of the first high-voltage terminal block 110. The first high-voltage terminal block 111 may also enclose a portion of the electric wire line connected to the first high-voltage terminal 110 .

[0106] The first high-voltage terminal 110 may include a groove 110-2. For example, the groove 110-2 may be formed by recessing a portion of the first high-voltage terminal 110.

[0107] The first high voltage terminal block 111 may include a locking portion 312. The locking portion 312 may be provided so that an end of the first high voltage terminal 110 side of the first high voltage terminal block 111 is locked into the groove portion 110-2.

[0108] The first block 310 may include a first coupling portion 311 for an interference fit. The second block 320 may include a second coupling portion 321 for an interference fit.

[0109] The first coupling portion 311 and the second coupling portion 321 are tightly fitted together, and the first high-voltage terminal block 111 can be attached to the first high-voltage terminal 110 .

[0110] The first high-voltage terminal 110 may include a protrusion 110-1. The protrusion 110-1 may protrude so as to limit movement of the first high-voltage terminal 110 of the first high-voltage terminal block 111 in the longitudinal direction.

[0111] The first high-voltage terminal block 111 is a terminal block that projects toward the first connector housing 100. block Since the protrusion 111-1 is included, movement relative to the first connector housing 100 can be limited.

[0112] When a force acts on the first high-voltage terminal block 111 in the direction opposite to the insertion direction, the first connector housing 100 block The protrusion 111-1 can be supported and the movement of the first high-voltage terminal block 111 can be restricted.
