Detailed Description
The invention will be further described with reference to the accompanying drawings.
The retaining frame of the electrical connector shown in fig. 1 comprises two mutually hinged half-frames, namely a first half-frame 1 and a second half-frame 2, which can be switched between a relatively closed state and a relatively open state, in which the relative angles of the first half-frame 1 and the second half-frame 2 are different. The main parts of the first half frame 1 and the second half frame 2 are U-shaped, the main parts of the two are provided with three side walls, under the relative closed state, as shown in figure 1, the end faces of the first half frame 1 and the end faces of the second half frame 2 are mutually parallel, namely, the relative angles of the two are 180 degrees, a closed rectangular frame body is formed by the two, the middle of the rectangular frame body is a through hole which penetrates up and down, the extending direction of the two relative rotating shafts is perpendicular to the penetrating direction of the through hole, and under the relative open state, as shown in figure 2, the included angle between the first half frame 1 and the second half frame 2 is an obtuse angle when seen in the axial direction of the two relative rotating shafts.
A plurality of first fixing holes 16 and a plurality of second fixing holes 27 are respectively formed on the first half frame 1 and the second half frame 2, and the number of the first fixing holes 16 on the first half frame 1 is consistent with the number of the second fixing holes 27 on the second half frame 2, and the first fixing holes and the second fixing holes are arranged in a one-to-one correspondence mode.
In actual use, a plurality of electrical connectors can be mounted between the first half frame 1 and the second half frame 2, two sides of the electrical connectors are respectively provided with raised fixing portions, and in a relatively closed state, the fixing portions on two sides of the electrical connectors are respectively embedded into a first fixing hole 16 and a second fixing hole 27, and the electrical connectors cannot be separated from the two half frames. In the relatively open state, the electrical connector is detachable with respect to the two half frames. The fixing portions on two sides of the electrical connector on the market have a size of one large and one small, so that in order to prevent the electrical connector from being reversely assembled when a user installs the electrical connector between the two half frames, the first fixing hole 16 and the second fixing hole 27 have a size of one large and one small, and thus, a foolproof effect can be achieved, so that the user can install the electrical connector in place at one time.
In order to relatively fix the two half frames in the relatively closed state, so that the two half frames cannot relatively rotate even if a certain external force is applied, 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, which does not always disengage from the first half-frame 1, so that there is no risk of dropping or even losing.
Specifically, as shown in fig. 3, the locking element 3 is in an i-shape and is composed of a middle sliding part 33 and a first part 34 and a second part 35 at two sides of the sliding part 33, two sides of the first half frame 1 are provided with flanging parts 17 extending from the side wall of the main body part and perpendicular to the side wall of the main body part, the flanging parts 17 are provided with sliding grooves 14, the sliding part 33 is in sliding fit with the sliding grooves 14, so that the locking element 3 can translate back and forth between a retracted 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 element 3 is provided with a jogging part 31, when the locking element 3 is in the locking position, the jogging part 31 and the second half frame 2 are jogged relatively, and the jogging relation refers to that the jogging part 31 and the local parts on the second half frame 2 can be mutually close to each other so that the jogging relation is formed between the jogging part and the two. In fact, a number of structures are possible which are to be considered as falling within the scope of the present invention, the first portion 34 and the second portion 35 being longer than the sliding portion 33, so that they have portions extending beyond the sliding portion 33, the engaging portion 31 being a clamping groove formed between the first portion 34 and the second portion 35, the second half-frame 2 having a main flange 25 thereon, the clamping groove clamping an edge of the main flange 25 to achieve the engagement of the two when the locking element 3 is pushed to the locking position, as shown in fig. 4.
In addition, 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 chute 14 inside.
Preferably, in order to prevent the locking element 3 from sliding by mistake with respect to the first half-frame 1, the locking element 3 is provided with a stop structure which allows the locking element 3 to remain in the current position when the locking element 3 is in both the retracted position and the locking position. Specifically, the stop structure is a protrusion 32 on the sliding portion 33, and the sidewall of the chute 14 includes a stop groove 15 that is matched with the protrusion 32. In this embodiment, only one set of stop grooves 15 is provided on the side wall of the chute 14, and when the locking element 3 is in the retracted position, the protrusions are embedded in the stop grooves 15 (as shown in fig. 5), and when the locking element 3 is in the locked position, the protrusions are located at the ends of the chute 14 (as shown in fig. 4). In this way, it is achieved that the locking element 3 remains stable in both positions, the steady state in which the locking element 3 is located being released and slid only when the locking element 3 is subjected to a large pushing force. The locking element 3 is preferably made of plastic material.
In order to realize the relative rotation of the first half frame 1 and the second half frame 2, the first half frame 1 is provided with an extension arm 11, the end part of the extension arm 11 is a rotating 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 relatively, the first half frame 1 and the second half frame 2 are free to rotate relatively without other structural restrictions, which causes trouble to the assembly and disassembly operations of the electrical connector with respect to the holding frame, and the user needs to manually maintain the two half frames in a relatively closed state or a relatively open state, therefore, it is necessary to provide an additional structure to enable the two half frames to be kept stable in the two states respectively.
In this embodiment, the first half frame 1 is further formed with a stop catch 13 disposed outside the extension arm 11, the second half frame 2 is provided with an inflection point portion 23, the stop catch 13 can respectively maintain the two half frames in a relatively closed state and a relatively open state when the two half frames are located at both sides of the inflection point portion 23, as shown in fig. 6 and 7, the inflection point portion 23 is located at an outlet edge of the movable slot 22, i.e., a surface extending from a surface of the inflection point portion 23, extends toward an inside of the movable slot 22 and extends toward an outside of the movable slot 22. Therefore, the stop clamping point 13 is positioned on any side of the inflection point part 23, the inflection point part 23 can limit the stop clamping point 13 to enable the stop clamping point 13 not to naturally rotate, and only if the two half frames receive large torsion force, the stop clamping point 13 can rub the inflection point part 23 to the other side of the stop clamping point to enable the stop clamping point 13 to be kept stable in the other state. When the locking element 3 is kept in the retracted position, the stop structure can prevent the locking element 3 from falling off the first half frame 1 and even losing when the two half frames are in the opposite open state, thus avoiding unnecessary trouble, and when the locking element 3 is kept in the locking position, the stop structure can prevent the locking element 3 from sliding out of the current position by mistake and can not maintain the two half frames. The scheme has simple structure and is effective and reliable.
Preferably, a groove portion 24 for receiving the stopper stuck point 13 is formed at one side of the inflection point portion 23, and the groove portion 24 is formed outside the movable groove 22. The groove portion 24 plays a role of giving way, so that the stop clip 13 moves to one side where the stop clip is located and has a space for accommodating.
In addition, in the embodiment, the two half frames are all stamping formed sheet metal parts, and the sheet metal parts are preferably stamped and formed by stainless steel, so that compared with the traditional zinc alloy die casting forming and zinc plating rust prevention process, the stamping formed sheet metal part is less in form process and lower in cost.
In practical use, it is necessary to ground the two half frames to ground all the electrical connectors in the holding frame, preventing static electricity from damaging the electrical connectors or electrical connector leakage from jeopardizing the safety of people and equipment. For this purpose, a grounding pin needs to be provided on the holding frame.

As shown in fig. 8, each of the two sides of the second half frame 2 is provided with a main flange 25 and a limit flange 26, wherein the main flange 25 on one side is provided with a grounding pin male head 4 and a first fixing sleeve 7, the grounding pin male head 4 is provided with a bolt end and a mounting end, the first fixing sleeve 7 is arranged between the main flange 25 and the limit flange 26 on the side where the grounding pin male head is arranged, the first fixing sleeve 7 is arranged around the mounting end of the grounding pin male head 4, the mounting end of the grounding pin male head 4 is screwed with a first screw 8, the inward side (the side close to the main flange 25) of the limit flange 26 on the side is abutted against the first screw 8 (as shown in fig. 10), by the structure, the first fixing sleeve 7 plays a role of stopping rotation and keeping the stability of the grounding pin male head 4, and the first screw 8 can be used for fixing a wire to the mounting end of the grounding pin male head 4 due to the effect of the limit flange 26, and also plays a role of keeping the fixing the grounding pin male head 4 fixed, and indirectly fixing the first fixing sleeve 7. During installation, the first fixing sleeve 7 is plugged between the main flange 25 and the limit flange 26, the grounding pin male head 4 is inserted into a hole position on the main flange 25, the installation end of the grounding pin male head 4 is embedded into the first fixing sleeve 7, and finally the first screw 8 is screwed into the installation end of the grounding pin male head 4.
The grounding pin female head 5, the grounding pin protective sleeve 6 and the second fixing sleeve 9 are arranged on the main flange 25 on the other side of the second half frame 2, the grounding pin protective sleeve 6 plays a guiding role in the process that the grounding pin male head 4 on the other retaining frame is inserted into the grounding pin female head 5 on the retaining frame, the grounding pin female head 5 is provided with an inserting hole end and a fixed end, the grounding pin protective sleeve 6 is provided with an arc buckle 61 inserted into the reserved inserting hole on the main flange 25, the inserting end of the grounding pin female head 5 is wrapped by the grounding pin protective sleeve 6, the second fixing sleeve 9 is arranged between the main flange 25 and the limiting flange 26 on the side where the second fixing sleeve 9 is arranged around the fixed end of the grounding pin male head 4, the fixed end of the grounding pin female head 5 is connected with the second screw 10 in a screwed mode, and the inward side (the side close to the main flange 25) of the side abuts against the second screw 10. The function of the second screw 10 and the second fixing sleeve 9 corresponds to the function of the first screw 8 and the first fixing sleeve 7. The above-mentioned components are assembled in the following sequence, firstly, the arc-shaped buckle 61 of the grounding pin protecting sleeve 6 is inserted into the reserved inserting hole on the main flange 25, the arc-shaped buckle 61 can generate elastic deformation in the process of being inserted into the inserting hole, then, the second fixing sleeve 9 is arranged between the main flange 25 and the limit flange 26 on the side where the second fixing sleeve is located, then, the grounding pin female head 5 is assembled, the inserting hole end of the grounding pin female head is inserted into the grounding pin protecting sleeve 6, the fixed end of the grounding pin female head is embedded into the second fixing sleeve 9, the arc-shaped buckle 61 cannot generate elastic deformation, and therefore, the arc-shaped buckle 61 cannot be separated from the inserting hole under the action of external force, and therefore, the grounding pin female head 5 plays a fixing role on the grounding pin protecting sleeve 6, and finally, the second screw 10 is screwed into the fixed end of the grounding pin female head 5.
Preferably, the first fixing sleeve 7 and the second fixing sleeve 9 constrain the two half frames from two sides so that the two half frames are aligned upwards on the relative rotation axes of the two half frames.
