Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The holding frame of the electrical connector shown in fig. 1 comprises two half frames hinged to each other, namely a first half frame 1 and a second half frame 2; the two half frames can be switched between a relatively closed state and a relatively open state, and the relative angles of the first half frame 1 and the second half frame 2 are different in the two states. The main body parts of the first half frame 1 and the second half frame 2 are both U-shaped, the main body parts of the first half frame 1 and the second half frame 2 are provided with three side walls, in a relatively closed state, as shown in figure 1, the end surface of the first half frame 1 and the end surface of the second half frame 2 are parallel to each other, namely the relative angle of the two is 180 degrees, the two form a closed rectangular frame body, the middle of the rectangular frame body is provided with a through hole which is vertically communicated, and the extending direction of the relative rotating shafts of the two is vertical to the communicating direction of the through hole; in the relatively open state, as shown in fig. 2, an included angle between the first half frame 1 and the second half frame 2 is an obtuse angle when viewed in the axial direction of the first half frame and the second half frame relative to the rotation axis.

A plurality of first fixing holes 16 and a plurality of second fixing holes 27 are formed on the first half frame 1 and the second half frame 2, respectively, and the number of the first fixing holes 16 on the first half frame 1 is consistent with that of the second fixing holes 27 on the second half frame 2, and the first half frame 1 and the second half frame 2 are arranged in a one-to-one correspondence manner.

In practical use, a plurality of electrical connectors can be installed between the first half frame 1 and the second half frame 2, both sides of the electrical connectors are respectively provided with a convex fixing part, in a relatively closed state, the fixing parts at both sides of the electrical connectors are respectively embedded into one first fixing hole 16 and one second fixing hole 27, and the electrical connectors cannot be separated from the two half frames. In the relatively open state, the electrical connector can be disassembled and assembled relative to the two half frames. The sizes of the fixing portions on both sides of the electrical connector on the market are one large and one small, and in order to prevent the user from inverting the electrical connector when the electrical connector is installed between the two half frames, the sizes of the first fixing hole 16 and the second fixing hole 27 are one large and one small, so that the fool-proofing effect can be realized, and the user can install the electrical connector in place at one time.

In order to fix the two half frames relatively in the relatively closed state, so that the two half frames cannot rotate relatively even if a certain external force is applied to the two half frames, the locking elements 3 are arranged on two sides of the first half frame 1, and the locking elements 3 can establish a connection relationship with the second half frame 2 so that the two half frames can be kept relatively fixed in the relatively closed state. The locking element 3 is mounted on the first half-frame 1, it never disengages from the first half-frame 1, and therefore there is no risk of falling or even being lost.

Specifically, as shown in fig. 3, the locking element 3 is generally i-shaped and is formed by a central sliding portion 33 and first and

second portions

34 and 35 on either side of the sliding portion 33; both sides of the first half frame 1 are provided with flanging parts 17 which extend out from the side walls of the main body part of the first half frame and are vertical to the side walls of the main body part, the flanging parts 17 are provided with sliding grooves 14, and the sliding parts 33 are in sliding fit with the sliding grooves 14, so that the locking element 3 can be translated back and forth between a retracting position and a locking position relative to the first half frame 1; when the locking element 3 is in the retracted position, as shown in fig. 2, the first half frame 1 and the second half frame 2 can rotate relatively; the locking component 3 is provided with an embedding part 31, when the locking component 3 is at the locking position, the embedding part 31 is embedded with the second half frame 2, and the embedding relation refers to that: the fitting portion 31 and a partial portion of the second half frame 2 can be brought close to each other so that they have a cross-fitting relationship. In fact, there are many structures that conform to the above-mentioned embedding relationship, and these structures should be regarded as falling into the protection scope of the present invention, and the structures adopted in this embodiment are as follows: the first portion 34 and the second portion 35 are each longer than the length of the sliding portion 33 so that both have a portion extending beyond the sliding portion 33, the fitting portion 31 being a clip groove formed between the first portion 34 and the second portion 35; the second half-frame 2 has a main flange 25, and when the locking element 3 is pushed to the locking position, the clamping grooves clamp the edges of the main flange 25 to achieve engagement therebetween, as shown in fig. 4.

Furthermore, the first portion 34 and the second portion 35 are also wider than the width of the sliding portion 33, so that the locking element 3 has notches on both sides, and thus both sides of the first portion 34 and the second portion 35 wrap the sides of both sides of the sliding groove 14.

Preferably, in order to prevent the locking member 3 from sliding mistakenly relative to the first half frame 1, the locking member 3 is provided with a stop structure, and the stop structure can keep the locking member 3 at the current position when the locking member 3 is at the retracting position and the locking position. Specifically, the stop structure is a protrusion 32 on the sliding portion 33, and the side wall of the chute 14 has a stop groove 15 used in cooperation with the protrusion 32. In this embodiment, only one set of stop grooves 15 is disposed on the side wall of the sliding slot 14; when the locking element 3 is in the retracted position, the projection is embedded in the stop recess 15 (as shown in fig. 5); when the locking element 3 is in the locking position, the projection is located at the end of the slide groove 14 (as shown in fig. 4). In this way, it is achieved that the locking element 3 is kept in a stable state in both positions, and only when the locking element 3 is subjected to a large pushing force, the stable state in which the locking element 3 is placed is released and slides. The locking element 3 is preferably made of a plastic material.

In order to realize the relative rotation of the first half frame 1 and the second half frame 2, an extension arm 11 is formed on the first half frame 1, and the end part of the extension arm 11 is a rotation end 12; the second half frame 2 is provided with a hinge groove 21 matched with the rotating end 12 and a movable groove 22 for the extension arm 11 to move in; the extension arm 11 can move in the movable groove 22, and the two side edges of the movable groove 22 can limit the movable angle of the extension arm 11, so that the first half frame 1 and the second half frame 2 can only rotate within a limited angle range.

When the locking element 3 does not fix the first half frame 1 and the second half frame 2 relative to each other, if there is no other structural restriction, the relative rotation between the first half frame 1 and the second half frame 2 is relatively free, which may cause trouble in the operation of attaching and detaching the electrical connector to and from the holding frame, and the user needs to manually maintain the two half frames in the relatively closed state or the relatively open state.

In this embodiment, the first half frame 1 is further formed with a stop point 13 disposed outside the extension arm 11; the second half frame 2 is provided with an inflection point part 23, and the stop clamping points 13 on two sides of the inflection point part 23 can respectively enable the two half frames to maintain a stable state in a relatively closed state and a relatively opened state, as shown in fig. 6 and 7; the inflection portion 23 is located at an exit edge of the movable groove 22, i.e., in a plane extending from a surface of the inflection portion 23, extends toward an inside of the movable groove 22 extending toward one side of the inflection portion 23, and extends toward an outside of the movable groove 22 extending toward the other side of the inflection portion 23. Thus, the stopping stuck point 13 is located at any side of the inflection point part 23, the inflection point part 23 limits the stopping stuck point 13 to make it unable to rotate naturally, only if the two half frames receive a large twisting force, the stopping stuck point 13 will rub the inflection point part 23 to move to the other side to make the two keep stable state under the other state. When the locking element 3 is kept at the retracted position, the stop structure can prevent the locking element 3 from falling off or even losing from the first half frame 1 when the two half frames are in the relative opening state, thereby avoiding unnecessary troubles; when the locking element 3 is kept at the locking position, the stop structure can prevent the locking element 3 from mistakenly sliding out of the current position and being incapable of maintaining the two half frames. The scheme has simple structure, and is effective and reliable.

Preferably, a groove portion 24 for receiving the stopper click 13 is formed at one side of the inflection portion 23, and the groove portion 24 is formed outside the movable groove 22. The groove portion 24 has a yielding function, so that the stop clamping point 13 is accommodated in a space when moving to one side where the stop clamping point is located.

In addition, in this embodiment, two half frames are stamping formed sheet metal component, and it is preferred to be formed by stainless steel stamping, compares with the rust-resistant technology of zinc alloy die-casting shaping zinc-plating again that adopts stamping forming's sheet metal component form technology still less, and the cost is lower.
