Disclosure of Invention

However, as shown in fig. 1 (a) and (B), although the conventional USB male connector 10 'has become miniaturized, after the electronic product 20' such as a computer is inserted, a housing portion (i.e., a housing portion for holding and inserting the USB male connector) still protrudes beyond the electronic product 20', and excessive miniaturization also makes it inconvenient to insert and remove the USB male connector 10'. In particular, since the housing protrudes outside the electronic product, inconvenience and risk are brought about in use. For example, the protruding housing may be scratched or damaged by impact, resulting in poor communication connection, or shifting the position of electronic products such as computers, even falling from a high place, and in addition, when the USB male connector 10' is taken out, it is inconvenient to grasp and it is necessary to apply an external force of a certain or more to pull out the connector. Further, the USB male connector 10 'protrudes beyond the surface of the electronic product 20', and is also aesthetically unattractive. Therefore, it is desirable that the housing does not protrude excessively beyond the electronic product 20 'such as a computer when the USB male connector 10' is used.

The present utility model has been made in view of the above problems of the prior art, and an object of the present utility model is to provide a USB male connector in which a housing does not protrude excessively from an electronic product such as a computer when in use.

The present inventors have made intensive studies to achieve the above object, and as a result, have conceived that by providing a compression and ejection mechanism capable of making a housing slide telescopically with respect to a USB metal plug in a USB male connector, the housing can be contracted into an electronic product by contraction or compression of the compression and ejection mechanism when the USB male connector is used, and the housing is prevented from protruding excessively outside the electronic product, thereby completing the present utility model.

In addition, in view of the above improvement, according to the shape and structure of the USB male connector of the present utility model, the USB female socket in the USB structure or the USB port structure of the electronic product to be inserted may be appropriately adjusted accordingly, so that the USB male connector may be smoothly inserted into the electronic product body as much as possible, and the end face of the contracted housing may be substantially aligned with the outer surface of the electronic product body. For example, the USB port of the electronic product needs to extend a certain distance into the body based on the current structure, and a certain mating space is designed to enable the housing of the USB male connector to be accommodated in the electronic product. Furthermore, the whole side surface of the USB male connector can also keep a certain fit clearance with the internal space for accommodating the USB male connector in the electronic product body. However, in the present utility model, the description is mainly directed to improvement of the USB male connector. The USB structure includes a USB male connector and a USB female socket, but for convenience of explanation, the explanation and illustration of the USB female socket will be omitted in the following description and drawings.

(embodiment)

The USB male connector according to one embodiment of the present utility model includes: the USB metal plug is used for being inserted into the electronic product body; a housing for holding and inserting the USB male connector, which is located at a side opposite to the insertion side of the USB metal plug; and a compression and ejection mechanism which is arranged in the USB metal plug, one side of which is connected with the shell and can enable the shell to stretch and slide relative to the USB metal plug.

Fig. 2 (a) and (a') are a side sectional view and a top sectional view, respectively, of the compression and ejection mechanism of the USB male connector of the present utility model before being compressed. Fig. 2 (B) and (B') are a side sectional view and a top sectional view, respectively, of the compressed and ejection mechanism of the USB male connector of the present utility model. As shown in fig. 2 (a), (a '), (B) and (B'), the USB male connector 10 of the present utility model includes: a USB metal plug 11 for inserting into the electronic product body 20; a housing 12 for holding and inserting the USB male connector 10, which is located on a side opposite to the insertion side of the USB metal plug 11; and a compression and ejection mechanism 13 which is built in the USB metal plug 11, one side of which is connected to the housing 12, and which enables the housing 12 to slide telescopically with respect to the USB metal plug 11.

Here, as shown in fig. 2 (B) and (B'), after the USB male connector 10 is inserted into the electronic product body 20, the USB male connector 10 is in the following state: the compressing and ejecting mechanism 13 is compressed or pressed, a part of the USB metal plug 11 is retracted into the housing 12, and an end surface of the housing 12 opposite to the USB metal plug 11 is aligned with an outer surface of the electronic product body 20.

The term "the end face of the case 12 facing the USB metal plug 11 is aligned with the outer surface of the electronic product body 20" means that the end face of the case 12 facing the USB metal plug 11 (hereinafter, may be simply referred to as "the end face of the case 12") is substantially flush with the end face near the USB insertion port of the electronic product body 20.

The electronic product body 20 is not particularly limited as long as it is an electronic product that can be used by being plugged into a USB male connector. For example, there may be mentioned: computers, notebook computers, mice, various transmitters, receivers using USB male connectors, and the like. Examples of the USB male connector 10 include a USB disk, a USB male connector for a wireless mouse, and the like. The housing 12 may be made of plastic, or may be made of other materials such as wood and metal.

Therefore, the housing 12 of the USB male connector 10 of the present utility model does not protrude from the electronic product 20 such as a computer when the USB male connector is in use. Further, since the compression and ejection mechanism 13 can slide the USB metal plug 11 in a telescopic manner with respect to the housing 12, the housing 12 can be slid (or ejected) outward of the electronic product 20, particularly when the USB male connector 10 is taken out. Thus, not only is the appearance attractive when the USB male connector 10 is used, but also the inconvenience and risk of use due to the protruding housing 12 can be suppressed, and the USB male connector 10 can be stably used for a long period of time.

In addition, the compression and ejection mechanism 13 and the USB male connector 10 may be integrated from the viewpoint of reducing the number of components, and may be designed as a separate structure, but the present utility model focuses on providing the compression and ejection mechanism 13. The compression and ejection mechanism 13 is repeatedly compressed and reset (i.e., the housing 12 is repeatedly slid and retracted with respect to the USB metal plug 11), thereby realizing the retractility of the USB male connector 10 itself, and achieving the object of the present utility model.

In addition, from the viewpoints of not affecting the actual use of the USB male connector 10 and considering the influence on the internal space and structure of the electronic product, the case 12 may be recessed into the outer surface of the electronic product body 20 as needed, or the case 12 may be slightly protruded beyond the outer surface of the electronic product body 20 for easy removal. That is, the shortest distance between the end surface of the housing 12 facing the USB metal plug 11 and the outer surface of the electronic product body 20 may be within ±1.00mm, preferably within ±0.50mm, and most preferably within 0.00mm (i.e., the planes of both are perfectly aligned). Here, the "shortest distance between the end surface of the case 12 facing the USB metal plug 11 and the outer surface of the electronic product body 20" refers to the shortest distance between: a plane perpendicular to the longitudinal direction of the USB male connector 10 and tangential to the end surface of the housing 12 (a plane on the housing 12 side); a plane perpendicular to the insertion direction of the USB male connector 10 and tangential to the end face near the USB insertion port in the electronic product body 20 (a plane on the electronic product body 20 side). In the case where the end face of the case 12 or the end face of the electronic product body 20 is irregularly shaped, each of the end faces refers to the most protruding portion among the end faces. In the case of the above-mentioned value "+", it means that the housing 12 of the USB male connector 10 slightly protrudes out of the electronic product. In contrast, in the case where the above-mentioned value is "-", it means that the housing 12 of the USB male connector 10 is slightly retracted into the electronic product. From the viewpoint of operations such as insertion and removal of the USB male connector 10, the above-mentioned value is preferably "+" or 0.00mm. The above-mentioned numerical value is preferably "-" or 0.00mm from the viewpoints of reducing the risk of use of the apparatus, improving the stability of use, and the like.

In the case where other components such as a receiving antenna and a lead wire are further provided in the housing 12 of the USB male connector 10, the inter-surface distance may be further adjusted according to circumstances in combination with practicality, aesthetic properties, and the like, and the inter-surface distance is not limited to the above numerical range, and may be set to be wider.

The compression and ejection mechanism 13 of the present utility model may be configured as follows, for example. Fig. 3 is a diagram showing an example of the compression and ejection mechanism 13 of the present utility model. As shown in fig. 3, the compression and ejection mechanism 13 includes the following constitution: a compression return spring 131, one side of which is fixed in the USB metal plug 11 and the other side of which is connected to the housing 12 and can be compressed and reset in the telescopic sliding direction of the compression and ejection mechanism 13; a positioning slider 132 provided in the USB metal plug 11, having one end fixed to the housing 12, and slidable in a direction of compression and return of the compression return spring 131; and a positioning swing link 133 having a fixed side 133 (a) and a swing side 133 (b), the fixed side 133 (a) being fixed on a width center line in the USB metal plug 11, the swing side 133 (b) being swingable with respect to the fixed side 133 (a) on a plane parallel to a plane of the positioning slider 132, wherein the positioning slider 132 has a slide groove 132 (a), the fixed side 133 (a) being distant from the positioning slider 132 with respect to the swing side 133 (b), the swing side 133 (b) being provided in the slide groove 132 (a), and the swing side 133 (b) being moved along the slide groove 132 (a) to be positioned when the positioning slider 132 slides.

The width center line refers to the center line in the width direction of the USB metal plug 11, that is, the broken line in fig. 3.

In addition, although 2 compression return springs 131 are shown in fig. 3, the number thereof is not particularly limited, and may be 1 or more than 2. However, from the viewpoint of stability and practicality of operation, it is preferable to use 2 compression return springs 131 as shown in fig. 3, which are disposed on both sides of the positioning slider 132. In addition, elastic means such as a spring plate may be used instead of the spring.

In addition, the positioning slider 132 may be formed integrally with the housing 12 or may be formed separately. The materials may be the same or different.

In addition, in fig. 3, the sliding groove 132 (a) is a closed polygon or ring shape, and has a V-shaped path on a side away from the fixed side 133 (a) of the positioning link 133. Here, the slide groove 132 (a) functions as a guide rail and a positioning for the swing side 133 (b). Thereby, when the compression return spring 131 is compressed, the swing side 133 (b) of the positioning swing link 133 moves to the V-shaped path along one side path (the upper half path of the arrow shown in fig. 3) of the slide groove 132 (a) and is caught (positioned), thereby contracting a part of the USB metal plug 11 into the housing 12 (see the compressed state shown in the lower half of fig. 4). Thus, when the USB male connector 10 is used, the housing 12 does not protrude excessively from the electronic product such as a computer. Then, the housing 12 is further pressed in this state, so that the swing side 133 (b) of the positioning swing link 133 is released from the V-shaped path and moves to the initial position (see the pre-compression state shown in the upper half of fig. 4) along the other side path (the lower half path of the arrow shown in fig. 3) of the slide groove 132 (a), whereby the USB male connector 10 returns to the original initial state. As can be seen from fig. 4, the compression and ejection mechanism 13 causes the USB male connector 10 to generate a compression amount W before and after compression. By using the USB male connector 10 in this way, the inconvenience and risk of use due to the protruding housing 12 can be greatly reduced, the USB male connector 10 can be stably used for a long period of time, and the appearance is also attractive.

In addition, the sliding groove 132 (a) shown in fig. 3 and 4 is a closed polygon, but may be a ring shape. Furthermore, the sliding groove 132 (a) may also be of a non-closed shape, i.e. the sliding groove 132 (a) may also have only the path of the upper or lower half of the groove shown in fig. 3 and 4. As long as the swing side 133 (b) of the positioning swing link 133 can be moved, positioned and reset by the sliding groove 132 (a). In addition, the sliding grooves 132 (a) shown in fig. 3 and 4 are axisymmetric, but may not be axisymmetric as required.

Fig. 5 (a) is a top cross-sectional view of an example of a detent lever in the compression and ejection mechanism of the present utility model. Fig. 5 (B) is A-A cross-sectional view of fig. 5 (a). As shown in fig. 5 (B), the positioning link 133 may also be a substantially U-shaped link. In fig. 5 (B), the fixing side 133 (a) of the positioning swing link 133 is detachably fixed to the USB metal plug 11, and the swing side 133 (B) at the other section of the positioning swing link 133 is inserted into the sliding groove 132 (a). In order to facilitate the swinging and resetting of the swinging side 133 (b), a swinging guide mechanism may be attached to the fixed side 133 (a) as needed.

In addition, the positioning slider 132 may further have an auxiliary positioning slot for assisting the movement of the positioning slider 132 in the telescopic sliding direction of the compression and ejection mechanism 13, so that the movement of the positioning slider 132 is smoother.

As an example of the auxiliary positioning groove, as shown in fig. 6 (a) and (B), the auxiliary positioning groove 134 includes the following constitution: a positioning groove 134 (a) provided on the positioning slider 132 and extending in a direction parallel to the telescopic sliding direction of the compression and ejection mechanism 13; and a positioning rod 134 (b) fixed to the USB metal plug 11 and inserted into the positioning groove 134 (a).

The auxiliary positioning groove 134 shown in fig. 6 (a) and (B) is arranged on one side of the positioning slider 132, but may be arranged at other positions, for example, at substantially the center of the positioning slider 132, or the like.

An example of the compression and ejection mechanism of the present utility model is described above. The compressing and ejecting mechanism is repeatedly pressed in and ejected out, so that the retractility of the USB male connector is realized, and the purpose of the utility model is achieved.

The compression and ejection mechanism of the present utility model is not limited to the above configuration, and the USB metal plug 11 may be repeatedly slid and locked in a telescopic manner with respect to the housing 12.

The compression and ejection mechanism of the present utility model is not limited to be mounted in the USB male connector, and may be used as long as two or more members need to repeatedly slide and lock in a telescopic manner with respect to each other.

As described above, the USB male connector of the present utility model is described. Further, as described above, according to the external shape and structure of the USB male connector of the present utility model, the USB female socket in the USB structure or the USB port structure of the electronic product to be inserted can be adjusted accordingly, so that the USB male connector can be inserted into the electronic product body as smoothly as possible, and the end face of the housing after shrinkage is aligned with the external surface of the electronic product body. For example, the USB port of the electronic product needs to properly extend a certain distance into the body based on the current structure, and a certain mating space is designed to enable the housing of the USB male connector to be accommodated in the electronic product. Furthermore, the whole side surface of the USB male connector also maintains a certain fit clearance with the internal space for accommodating the USB male connector in the electronic product body.

In addition, the USB male connector of the present utility model may be used on an existing electronic product, and in this case, the USB male connector still protrudes out of the electronic product.

In addition, a USB structure according to another embodiment of the present utility model includes the above-described USB male connector and USB female socket.

In addition, an electronic product according to another embodiment of the present utility model includes the above-described USB male connector.

The present utility model has been described above in terms of presently preferred embodiments, but such disclosure should not be construed as limiting. Various modifications and alterations will become apparent to those skilled in the art in light of the foregoing disclosure. It is therefore intended that the appended claims be interpreted as including all such alterations and modifications as fall within the true spirit and scope of the utility model.
