Detailed Description

To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 14, the present invention discloses a fixing device and an electronic apparatus, the fixing device includes a receiving portion 100, a first limiting member 200 and a second limiting member 300. The electronic equipment comprises an equipment body 400, a connecting wire 500 and the fixing device, wherein the socket 410 is arranged on the equipment body 400, the connecting wire 500 comprises a plug 510 and a cable 520, the plug 510 and the socket 410 are in plug fit along a first direction, and the fixing device can fix the plug 510 and the socket 410 in plug fit so as to prevent the plug 510 and the socket 410 from being separated from each other under the action of a certain external force. In addition, for convenience of description hereinafter, a direction in which the header 510 and the receptacle 410 are inserted into each other is taken as a first direction, a direction around the insertion direction of the header 510 and the receptacle 410 is taken as a second direction, and a direction perpendicular to the insertion direction of the header 510 and the receptacle 410 is taken as a third direction; here, the first direction and the third direction may be a direction a and a direction B in fig. 14, respectively, and the second direction may be a direction R in fig. 11.

As shown in fig. 1 to 9, the receiving portion 100 has a receiving cavity 110, a first opening 120 and a second opening 130, and both the first opening 120 and the second opening 130 communicate with the receiving cavity 110. During the use of the fixing device, the plug 510 may be received in the receiving cavity 110, the cable 520 connected to the plug 510 may pass through and extend out from the second opening 130, so as to ensure that the other end of the cable 520 can be connected to other components, the first opening 120 may allow the plug 510 and/or the socket 410 to pass through, so that during the process of inserting and matching the plug 510 and the socket 410 into each other, the plug 510 may extend out from the first opening 120 in the receiving cavity 110 and be inserted into the socket 410, and/or the socket 410 may extend into the receiving cavity 110 from the first opening 120 and be inserted into the plug 510, so as to ensure that the socket 410 and the cable 520 can still perform the inserting and matching work with the socket 410 under the condition that the receiving portion 100 is installed on the socket 410 and the cable 520.

The receiving portion 100 is engaged with the plug 510 such that the position of the plug 510 is restricted by the receiving portion 100 and the plug 510 is prevented from moving away from the socket 510 and being separated from the socket 510. For example, the size of only the first opening 120 of the receptacle 100 may be larger than the minimum size of the plug 510, which ensures that the plug 510 has no other capability of moving relative to the receptacle 100 except that it extends out of the receptacle 110 from the first opening 120. One of the first limiting member 200 and the second limiting member 300 is mounted on the socket 410, and the other is connected to the accommodating portion 100, so that after the first limiting member 200 and the second limiting member 300 are completely clamped and matched, the plug 510 and the socket 410 which are fixedly inserted and matched in the first direction are achieved. Meanwhile, a detachable fit relationship is formed between the first limiting member 200 and the second limiting member 300, so that when the plug 510 and the socket 410 need to be separated, a worker can firstly disassemble the first limiting member 200 and the second limiting member 300, and then apply a certain pulling force, so that the plug 510 can be pulled out from the socket 410, and the separation work of the plug 510 and the socket 410 is completed.

Specifically, the receiving portion 100 may be made of metal or plastic, and preferably, the receiving portion 100 may be made of plastic, which has relatively low cost, and is generally non-conductive, so that the plug 510 and the socket 410 can be protected to some extent, and the plastic is hard, so that the plug 510 can be protected by the receiving portion 100. Of course, the accommodating portion 100 may also be made of other hard materials, so that when the plug 510 is inserted into the socket 410 and the first limiting member 200 is engaged with the second limiting member 300, the accommodating portion 100 can provide a limiting effect for the plug 510 in the first direction, and the accommodating portion 100 made of hard materials can further ensure that the plug 510 and the socket 410 form a more reliable limiting engagement relationship in the first direction.

The size and shape of the receiving cavity 110, the first opening 120, and the second opening 130 in the receiving portion 100 may be selected according to the size and shape of the plug 510 and the cable 520 to be mated. For example, the receiving cavity 110 may have a cylindrical structure, and each of the first opening 120 and the second opening 130 may have a circular hole structure; in the third direction, i.e. the direction perpendicular to the plugging direction of the plug 510 and the socket 410, the minimum dimension of each of the receiving cavity 110 and the first opening 120 may be slightly larger than the maximum dimension of the plug 510, and the dimension of the second opening 130 may be larger than the dimension of the cable 520, so as to ensure that the plug 510 and the cable 520 can rotate in the receiving cavity 110 and the second opening 130, respectively, to adapt to the orientation of the socket 410.

The first limiting member 200 and the second limiting member 300 are combined structures capable of forming a detachable clamping relationship, and both can be made of hard materials such as plastics or metals. For example, in the first limiting member 200 and the second limiting member 300, the first limiting member 200 may be made of a material having an elastic ability, the first limiting member 200 is engaged with the second limiting member 300, and during the detachment and separation process, the first limiting member 200 is elastically deformed to a certain extent by pressing or pulling, so as to be separated from the second limiting member 300. Or, an elastic member such as a spring may be directly disposed inside the first limiting member 200, and by virtue of the expansion capability of the elastic member, the first limiting member 200 and the second limiting member 300 can form a reliable clamping fit relationship; in the separating process, the elastic member may be pressed to disable the locking relationship between the first limiting member 200 and the second limiting member 300, thereby completing the separation of the first limiting member 200 and the second limiting member 300. Of course, there are various clamping combination structures with detachable capability, and the specific structures of the first limiting member 200 and the second limiting member 300 will not be described herein too much.

In addition, the entire fixing device is used in cooperation with the device body 400 of the electronic device. The first limiting member 200 may be connected to the accommodating portion 100, and the second limiting member 300 may be mounted on the device body 400 and cooperate with the socket 410. In the case that the first limiting member 200 and the second limiting member 300 are snap-fitted, the positional relationship between the plug 510 and the socket 410 which are snap-fitted in the first direction can be fixed, thereby preventing the plug 510 and the socket 410 from being separated from each other by an external force. Alternatively, the second limiting member 300 is connected to the accommodating portion 100, and the first limiting member 200 is mounted on the device body 400 and is matched with the socket 410, which is not limited herein. It should be noted that, one of the first limiting member 200 and the second limiting member 300 connected to the accommodating portion 100 may be formed integrally with the accommodating portion 100, which may ensure that the connection reliability between the two is relatively high, thereby further improving the reliability of the fixing relationship between the plug 510 and the socket 410.

Further, as shown in fig. 8, 10, 11 and 12, the first limiting member 200 may include a sidewall 210 and a buckle 220, the sidewall 210 is an annular structure, the buckle 220 is connected to an inner side of the sidewall 210, the buckle 220 is detachably connected to the second limiting member 300, and when the first limiting member 200 and the second limiting member 300 are engaged with each other, the second limiting member 300 is located in the sidewall 210.

When the above structure is adopted, the sidewall 210 of the first limiting member 200 can provide a certain protection effect for the second limiting member 300; moreover, the buckle 220 is arranged in the side wall 210, so that even if the electronic device collides or interferes with other components, the buckle 220 is not damaged basically under the protection action of the side wall 210; moreover, the clamping fit relationship between the buckle 220 and the second limiting member 300 is not damaged, so that the fixed relationship between the plug 510 and the socket 410 is stable.

Specifically, the latch 220 and the sidewall 210 can be formed by an integral molding method, which can ensure that the entire first limiting member 200 has high overall structural stability. The number of the snap 220 may be one, two or more, and is not limited herein. The specific shape of the clip 220 can be determined according to actual conditions, and the clip 220 can be a triangular prism or a quadrangular prism, so that the clip 220 and the second limiting member 300 with such a structure form a reliable snap fit relationship. The sidewall 210 may have a circular ring structure, or the sidewall 210 may have a square ring structure, but the sidewall 210 may have other ring structures, which is not limited herein.

Further, as shown in fig. 7, the sidewall 210 may be connected to the accommodating portion 100, that is, the first limiting member 200 is connected to the accommodating portion 100, and correspondingly, the second limiting member 300 is connected to the apparatus body 400. Compared with the case that the first limiting member 200 is connected with the device body 400, in the above scheme, the first limiting member 200 connected with the accommodating portion 100 can be directly sleeved on the outer side of the second limiting member 300, the operation process is relatively simple and convenient, and the first limiting member 200 can provide a protection effect for the second limiting member 300; meanwhile, since the first limiting member 200 is connected to the accommodating portion 100, only the device body 400 is exposed to the outside of the whole electronic device, and the accommodating portion 100 is connected to the first limiting member 200, which reduces the gap between the whole electronic device and the outside, thereby reducing the probability of external dust or foreign matters entering the accommodating portion 100, and ensuring that the electrical connection relationship between the plug 510 and the socket 410 is not easily affected by foreign matters such as dust, and is stable.

As mentioned above, in the using process of the fixing device, the first limiting member 200 is sleeved on the outer side of the second limiting member 300. In order to reduce the difficulty in the sleeving process between the first limiting member 200 and the second limiting member 300, as shown in fig. 4, preferably, an end of the second limiting member 300 facing the first limiting member 200 may be an inclined guiding end 310. Under the guiding and avoiding action of the inclined guiding end 310, the first limiting member 200 is more easily sleeved on the second limiting member 300, thereby further reducing the workload of fixing the plug 510 and the socket 410 by a fixing device.

Specifically, the side surface of the inclined guiding end 310 may be an arc-shaped structure or a planar structure, the inclined guiding end 310 may be integrally formed with the forming process of the second limiting member 300, and the specific size, inclination and other parameters of the inclined guiding end 310 may be determined according to actual conditions. In the above embodiment, the gap between the inner wall of the first limiting member 200 and the outer wall of the second limiting member 300 can be made as small as possible, so as to further improve the protection effect of the first limiting member 200 on the second limiting member 300, the plug 510 and the socket 410, and since the relative movement range of the first limiting member 200 and the second limiting member 300 in the third direction is smaller, the matching relationship between the first limiting member 200 and the second limiting member 300 is more stable.

As described above, the first limiting member 200 and the second limiting member 300 can be connected by other methods besides the elastic clamping method, so as to form a detachable clamping fit relationship. As shown in fig. 3-6 and 10-12, the second limiting member 300 may be provided with a retaining notch 320 and a fitting notch 330, and in a first direction, the first limiting member 200 may extend into the fitting notch 330 to form a movable connection relationship with the second limiting member 300, so that the first limiting member 200 and the second limiting member 300 may move relatively in the first direction. Meanwhile, the clamping gap 320 is communicated with the matching gap 330, when the first limiting member 200 extends into the matching gap 330 along the first direction, since the clamping gap 320 and the matching gap 330 are arranged along the second direction, the first limiting member 200 can continue to rotate relative to the second limiting member 300 along the second direction, and along with the rotation process of the first limiting member 200, the first limiting member 200 can extend into the clamping gap 320 and form a reliable limiting matching relationship with the second limiting member 300 along the first direction, that is, the first limiting member 200 and the second limiting member 300 are clamped and matched in the first direction.

Conversely, in the process of splitting the first limiting member 200 and the second limiting member 300, the first limiting member 200 can be disengaged from the retaining notch 320 by rotating the first limiting member 200 in the second direction in the opposite direction, and move to the matching notch 330; then, the first limiting member 200 is moved in the first direction in a reverse direction, so that the first limiting member 200 moves along the matching notch 330, and the first limiting member 200 can be separated from the second limiting member 300, thereby completing the separation of the first limiting member 200 and the second limiting member 300.

Specifically, when the first limiting member 200 and the second limiting member 300 are rotatably engaged along the second direction to form a detachable clamping relationship, both the first limiting member 200 and the second limiting member 300 can be circular structures, and the two are sleeved together, so that the first limiting member 200 and the second limiting member 300 can form a rotatably engaged relationship. The size of the matching gap 330 can be slightly larger than the size of the matching portion of the first limiting member 200 with the matching gap 330, so as to ensure that the first limiting member 200 can freely move in the matching gap 330; accordingly, the size of the holding gap 320 engaged with the first limiting member 200 can be slightly larger than the size of the first limiting member 200.

More specifically, by designing the span of the retaining notch 320 in the second direction, the first limiting element 200 can be switched cyclically between the retaining notch 320 and the matching notch 330 along the second direction, that is, during the rotation of the first limiting element 200 along the second direction, the state of matching with the retaining notch 320 is switched to the state of matching with the matching notch 330, and then the state of matching with the retaining notch 320 is switched, and the cycle is repeated.

Alternatively, the first limiting element 200 can enter the holding gap 320 from the matching gap 330 in a rotation direction opposite to the rotation direction entering the matching gap 330 from the matching gap 320 by designing the span of the holding gap 320 in the second direction. In this case, of the opposite sides of the fitting notch 330 in the second direction, only one side may be provided with the holding notch 320, or both sides may be provided with the holding notches 320 at the same time; in other words, in the second direction, the holding indentation 320 has a bottom structure, so that the first limiting element 200 cannot move continuously after moving a distance in the holding indentation 320.

As mentioned above, the dimension spanned by the holding gap 320 in the second direction can be designed, so that the first limiting member 200 cannot rotate inwards after entering the holding gap 320 for a certain distance. When the structure is adopted, since the first limiting member 200 can not move continuously after moving a distance from the matching notch 330 to the retaining notch 320, the situation that the first limiting member 200 is directly screwed out from the other end of the matching notch 330 after being screwed into the retaining notch 320 from one end of the matching notch 330 under the action of the rotating force can be prevented, and the first limiting member 200 and the second limiting member 300 can form a reliable limiting matching relationship in the first direction after moving a certain distance from the matching notch 330 to the retaining notch 320 is ensured.

Further, the first limiting element 200 and the second limiting element 300 are limited and matched in the direction that the retaining notch 320 points to the matching notch 330. Specifically, as shown in fig. 11, only one of two opposite sides of the matching notch 330 along the second direction is provided with the retaining notch 320, so that when the first limiting member 200 reversely moves from the retaining notch 320 to the matching notch 330, due to the blocking effect of the second limiting member 300, a user can directly obtain the information that the first limiting member 200 has moved to the matching notch 330, and then only the first limiting member 200 needs to move along the first direction, so as to complete the separation work of the first limiting member 200 and the second limiting member 300. Compare in the scheme that the relative both sides of cooperation breach 330 all were provided with the card and hold breach 320, above-mentioned embodiment can avoid first locating part 200 to hold the back of deviating from in breach 320 from a card, directly stretches into to another card and hold breach 320 in, reduces the utility model discloses a fixing device's convenience of use.

Further, as shown in fig. 11, in the third direction, the holding notch 320 and the matching notch 330 can be located outside the second limiting member 300. The first position-limiting member 200 may include a buckle 220 and a rib 230, and the buckle 220 may extend into the retaining notch 320 to be position-limited and matched with the second position-limiting member 300 in the first direction; the convex rib 230 is connected with the buckle 220, the convex rib 230 is located on one side of the buckle 220 facing the second limiting member 300, and the convex rib 230 is in press fit with the second limiting member 300, so that the stability of the limiting fit relation between the first limiting member 200 and the second limiting member 300 can be further improved, and the buckle 220 is prevented from being separated from the clamping notch 320 under the condition that a fixing device or an electronic device is collided or swayed, so that the clamping relation between the first limiting member 200 and the second limiting member 300 is disabled.

Specifically, the buckle 220 and the rib 230 may be formed by an integral injection molding, and the rib 230 may be a columnar structure protruding toward the second position-limiting member 300, so as to ensure that the rib 230 and the second position-limiting member 300 can be pressed against each other.

Preferably, as shown in fig. 11, a portion of the second limiting member 300 facing the retaining notch 320 may be provided with an in-place notch 340, and when the buckle 220 extends into the retaining notch 320, the rib 230 also extends into the in-place notch 340 and forms a limiting fit relationship with the second limiting member 300 in the second direction. In addition, in the process that the buckle 220 moves from the engaging notch 330 to the retaining notch 320, the protruding rib 230 is switched from the state of being press-fitted with the second limiting member 300 to the state of being fitted with the in-place notch 340, and at the time when the protruding rib 230 and the in-place notch 340 form a fitting relationship, because the pressed amplitude of the protruding rib 230 decreases, an obvious pause feeling can be generated, so that the user can know that the buckle 220 has reached the preset position of the retaining notch 320 by obtaining the pause feeling, and obviously, when the buckle 220 reaches the preset position, the first limiting member 200 and the second limiting member 300 can form a reliable limiting fitting relationship in the first direction.

Specifically, the overall structure of the in-place gap 340 may be designed according to the overall structure of the rib 230, so as to ensure that the rib 230 and the in-place gap 340 can form a stable fit relationship. In addition, in order to ensure that the difficulty in matching and detaching the rib 230 and the in-place notch 340 is relatively low, the edges of the rib 230 and the in-place notch 340 which are matched with each other can be set into structures with a certain guiding function, such as arcs. In addition, the number of the rib 230 and the in-place gap 340 can be one or more, and in order to reduce the convenience of the fixing device, it is preferable that the number of the rib 230 and the in-place gap 340 is one, and the positions of the rib 230 and the in-place gap 340 correspond to each other.

Optionally, in order to improve the convenience of the whole fixing device, preferably, the number of the matching notches 330 may be multiple, the multiple matching notches 330 are arranged at intervals along the second direction, and the clamping notch 320 is connected between at least two adjacent matching notches 330. Specifically, the plurality of mating notches 330 may be identical or different in structure and size. In the second direction, the angle spanned between any two adjacent matching notches 330 can be determined according to practical situations, and is not limited herein.

In the case that the second limiting member 300 adopts the above structure, the number of the parts of the first limiting member 200, such as the buckle 220, which can form a limiting fit relationship with the second limiting member 300, may be one or more. When the number of the fasteners 220 is one, when the first limiting member 200 and the second limiting member 300 need to be assembled, the fasteners 220 can be engaged with any one of the engaging notches 330 and then move relative to the second limiting member 300 along the first direction, and then the fasteners 220 can move along the second direction and then engage with the retaining notches 320, thereby achieving the purpose of limiting and connecting the first limiting member 200 and the second limiting member 300 in the first direction. Correspondingly, in the process of splitting the first limiting member 200 and the second limiting member 300, the buckle 220 only needs to move to the position of any matching notch 330 along the second direction, and then moves along the first direction, so as to complete the work of separating the first limiting member 200 and the second limiting member 300, and thus, the process of dismounting and mounting the first limiting member 200 and the second limiting member 300 is relatively simple, and the difficulty is low.

Under the condition that the number of the fasteners 220 of the first limiting member 200 is multiple, the number of the matching notches 330 is also multiple, and the matching notches 330 are matched with the fasteners 220 in a one-to-one correspondence manner, so that the first limiting members 200 can be matched with the matching notches 330 along the first direction to move relative to the second limiting member 300. Accordingly, in order to ensure that the plurality of buckles 220 and the second limiting member 300 can form a limiting matching relationship in the first direction, any matching notch 330 can be provided with a clamping notch 320, so that each buckle 220 can rotate from a different matching notch 330 to match with a different clamping notch 320, and the stability of the limiting matching relationship between the first limiting member 200 and the second limiting member 300 in the first direction is improved.

Specifically, in the plurality of buckles 220 of the first limiting member 200, the angles between any two adjacent buckles 220 along the second direction may be the same or different. Under the condition that the angles of any two adjacent buckles 220 at intervals along the second direction are different, the relative position relationship between the plurality of matching notches 330 needs to be determined according to the position distribution relationship between the plurality of buckles 220, so that the first limiting member 200 of the setting structure can be matched with the plurality of matching notches 330, and the purpose of moving relative to the second limiting member 300 along the first direction is achieved.

Preferably, the angle of the interval between any two adjacent latches 220 is the same, and correspondingly, the angle of the interval between any two adjacent matching notches 330 is also the same and equal to the angle of the interval between two latches 220. Under the circumstances, when the first limiting member 200 and the second limiting member 300 are mutually matched, the first limiting member 200 does not need to be rotated to a specific angle, and only one buckle 220 needs to be rotated to the position of one matching notch 330, so that the remaining buckles 220 can be ensured to form a matching relationship with the remaining matching notches 330, and then the whole first limiting member 200 is directly pulled out from the second limiting member 300 along the first direction, so that the operation process is relatively simple, and the operation complexity is relatively low.

It is considered that the corresponding operation actions, such as rotation and insertion and extraction, are required to be performed on the components connected to the receiving part 100 during the use of the fixing device. Preferably, a non-slip part (not shown) may be disposed on an outer surface of the accommodating part 100, so that a friction force between the user and the accommodating part 100 is increased by the non-slip part, thereby facilitating the operation and preventing the occurrence of a slip phenomenon. Specifically, the anti-slip portion may be an anti-slip sleeve made of a flexible material such as rubber, which can be sleeved on the accommodating portion 100 to provide an anti-slip function. Or the anti-skid part can also be an anti-skid pattern, and the structure is relatively simple and convenient in forming process and relatively low in cost.
