Detailed Description

The features and capabilities of the present invention are described in further detail below in connection with the examples.

The scheme principle of the connector plug in the invention is as follows:

A connector plug as shown in fig. 1-4 comprises a plug housing 1 and an outer conductor assembly 2. The plug housing 1 may in particular, as shown in fig. 5, comprise a plurality of insertion chambers 3 for inserting the outer conductor assemblies 2. The outer conductor assembly 2 is inserted into the insertion cavity 3 from the tail end of the plug housing 1 and is fixedly connected with the plug housing 1 into a whole through a fastening structure 9 arranged on the plug housing 1. After the plug-in mounting is completed, a wire sealing body 4 is additionally arranged at the tail end of the plug housing 1. The wire sealing body 4 is pressed and held in the plug housing 1 through a tail cover 5 which is buckled at the tail end of the plug housing 1. The outside of the plug housing 1 is also provided with CPA locking tabs 6 for use of the connector plug. The above arrangement is of prior art and is therefore not described in detail.

The outer conductor assembly 2 is shown in fig. 6-8 and includes a fixedly attached crimped outer conductor 7 and a contact outer conductor 8. An insulator 20 is inserted inside the crimp outer conductor 7 and the contact outer conductor 8. The crimp outer conductor 7 and the contact outer conductor 8 are looped one over the other, crimped together, and then the fixed connection between the two is further fixed by laser welding. When the crimp outer conductor 7 is located outside and the contact outer conductor 8 is located inside, a clamping space into which the fastening structure 9 of the plug housing 1 is fastened may be provided on the crimp outer conductor 7, and a reinforcing fastening structure corresponding to the clamping space may be provided on the contact outer conductor 8. When the crimp outer conductor 7 is located inside and the contact outer conductor 8 is located outside, a clamping space into which the fastening structure 9 of the plug housing 1 is fastened may be provided on the contact outer conductor 8, and a reinforcing clamping structure corresponding to the clamping space may be provided on the crimp outer conductor 7. The fastening structure 9 on the plug housing 1 is simultaneously fastened into the fastening space and the reinforcing fastening structure. Through the means, the contact area between the buckling structure 9 and the contact outer conductor 8 can be increased, the pulling force required by pulling the outer conductor assembly 2 out of the plug housing 1 is effectively improved, and the outer conductor assembly 2 is not easy to pull out of the plug housing 1 during plug insertion and extraction. Simultaneously, the structure also enables the pulling-out force during plug insertion to act on the crimping outer conductor 7 and the contact outer conductor 8 at the same time, and the stress effect is better. Compared with the technical scheme that only a single component acts on the tension releasing force in the prior art, the technical scheme can avoid the situation that the connection relation between the component and other components is damaged due to the fact that the single component is stressed too much on the outer conductor assembly 2. Therefore, with the structure, the outer conductor assembly 2 can be prevented from being pulled out from the plug housing 1 during plug insertion and removal due to the pulling force of the outer conductor assembly 2, and the operation during plug insertion is greatly facilitated.

Based on the above scheme principle, embodiment 1 of the connector plug of the present invention is:

A connector plug, the structure of which can be referred to the connector plug shown in fig. 1-4, comprises a plug housing 1 and an outer conductor assembly 2. The structure of the plug housing 1 can be seen with reference to fig. 5. The outer conductor assembly 2 is inserted into the plug housing 1 and is fixedly connected with the plug housing 1 into a whole by a fastening structure 9 on the plug housing 1. The structure of the outer conductor assembly 2 may be as shown with reference to fig. 6-8, including fixedly connecting the crimped outer conductor 7 with the contact outer conductor 8. The crimp outer conductor 7 and the contact outer conductor 8 are looped one over the other, crimped together, and then the fixed connection between the two is further fixed by laser welding. One of the two is provided with a clamping space for clamping the clamping structure 9 of the plug housing 1, and the other is provided with a reinforcing clamping structure corresponding to the clamping space. By the means, the contact area between the buckling structure 9 and the contact outer conductor 8 is increased, and the pulling-out force required by pulling out the outer conductor assembly 2 from the plug housing 1 is further effectively improved.

The key point of this embodiment is that the clamping space is specifically the clamping through hole 10. The clamping through hole 10 and the reinforcing clamping structure are arranged on the part which is overlapped with the contact outer conductor 8 and the crimp outer conductor 7 in a ring mode, so that the clamping structure 9 is clamped into the clamping through hole 10 and the reinforcing clamping structure at the same time. This increases the pulling-out force required for pulling out the outer conductor assembly 2 from the plug housing 1. Meanwhile, when the outer conductor assembly 2 is acted by a pulling-out force, the pulling-out force can act on the contact outer conductor 8 and the compression joint outer conductor 7 at the same time, so that the failure of the fixed connection relation between the contact outer conductor 8 and the compression joint outer conductor 7 is avoided.

On the basis of the above structure, the reinforcing clamping structure may be specifically a clamping sink 11. The clamping sinking groove 11 has a simple structure and is convenient to process and assemble. Meanwhile, the sinking groove structure does not occupy extra space, and is more suitable for a plug structure with compact space. It is of course conceivable that the reinforcement clip-on structure here can also be embodied as a through-hole structure. This further increases the contact area of the snap-on structure 9 with the contact outer conductor 8, but affects the structural strength of the piece in which the reinforcement snap-on structure is located.

It should be noted here that the fitting space may be a space at an end edge position of one of the contact outer conductor 8 and the crimp outer conductor 7 located on the outer side, in addition to the structure employing the fitting through hole 10. Correspondingly, the reinforcing clamping structure is a step surface which is arranged on the other one and corresponds to the edge position of the end part. The snap-on structure 9 of the plug housing 1 is simultaneously in a stop-fit with the aforementioned edge and step surface. When the contact outer conductor 8 is located outside the crimp outer conductor 7, a space after the edge of the contact outer conductor 8 facing away from the insertion direction of the outer conductor assembly 2 is used as a fitting space. The crimp connection outer conductor 7 comprises a large-diameter section and a small-diameter section, and a parting step surface and a step surface of the large-diameter section and the small-diameter section are used as reinforcing clamping structures. The large-diameter section is inserted into the contact outer conductor 8 along the insertion direction of the outer conductor component 2, and the parting step surfaces of the large-diameter section and the small-diameter section are coplanar with the edge of the contact outer conductor 8, which is opposite to the insertion direction of the outer conductor component 2, so that the clamping structure 9 is in stop fit with the parting step surfaces. After the outer conductor assembly 2 is inserted into the corresponding position of the plug housing 1, a certain stop surface on the outer conductor assembly 2 is in stop fit with another stop surface on the plug housing 1 so as to prevent the outer conductor assembly 2 from moving along the insertion direction; the fastening structure 9 is simultaneously in blocking fit with the edge of the outer conductor facing away from the insertion direction of the outer conductor assembly 2 and the parting step surface of the large-diameter section and the small-diameter section of the crimping outer conductor 7, so as to prevent the outer conductor assembly 2 from moving in a direction away from the insertion direction. The structure does not need to open holes or slots on the contact outer conductor 8 and the press-connection outer conductor 7, so that the structural strength of the contact outer conductor 8 and the press-connection outer conductor 7 can be effectively ensured.

The groove shape of the clamping sinking groove 11 is preferably a sinking groove with the same shape as the clamping through hole 10. The groove shape of the clamping sinking groove 11 is identical to the clamping through hole 10, so that the clamping sinking groove 11 can be aligned with the clamping through hole 10 conveniently. Meanwhile, during design and processing, the groove shape of the clamping sinking groove 11 and the clamping through hole 10 are in the same shape, so that calculation and positioning are convenient. Of course, this does not mean that the groove shape of the snap-in countersink 11 must be congruent with the snap-in through hole 10. In some cases, if the assembly accuracy of the contact outer conductor 8 and the crimp outer conductor 7 is not high, the groove shape of the snap-fit countersink 11 may be specifically set to be a long-shaped groove, and the snap-fit through hole 10 may be specifically set to be a circular through hole. This facilitates the fitting of the snap-in countersink 11 with the snap-in through hole 10 against assembly errors when aligned. Of course, the groove type of the snap-in sinking groove 11 may be a circular groove, and the snap-in through hole 10 may be a long-strip through hole.

Further, the groove-like shape of the snap-fit countersink 11 can be aligned with the snap-fit through hole 10 in a uniform size. Therefore, after the clamping sinking groove 11 is assembled with the clamping through hole 10, the hole and the space in the groove are integrally communicated, and no additional structure is arranged in the space to prevent the clamping of the clamping structure 9 on the adaptive plug shell 1, so that the clamping through hole 10, the clamping sinking groove 11 and the clamping structure 9 are assembled in place, and the pulling-out force of the outer conductor assembly 2 is ensured to be in an expected range. Of course, the slot size of the clamping countersink 11 can be larger or smaller than that of the clamping through hole 10, so that the clamping countersink 11 and the clamping through hole 10 can overcome assembly errors in alignment. In some special cases, the groove shape of the clamping sinking groove 11 and the clamping through hole 10 can be arranged in a non-aligned mode. If the clamping sinking groove 11 is a rectangular groove, the clamping through hole 10 is a rectangular hole, the length direction of the rectangular groove is perpendicular to the length direction of the rectangular hole, and the length direction of one of the rectangular groove and the rectangular hole is consistent with the axial direction of the outer conductor assembly 2. With this structure, it is ensured that the one of the crimp outer conductor 7 and the contact outer conductor 8 located on the outer side can be fine-tuned in the circumferential direction or the axial direction with respect to the one located on the inner side, and that the fine-tuning does not affect the size of the space into which the snap structure 9 can be snapped. Of course, the length direction of the rectangular groove and the rectangular hole may be identical to the axial direction of the outer conductor assembly 2, and the rectangular groove and the rectangular hole may be partially overlapped in the length direction. This allows the outer one of the crimp outer conductor 7 and the contact outer conductor 8 to be trimmed axially relative to the inner one, so that the space into which the snap-in structure 9 can be snapped in can be enlarged or reduced in the axial direction of the outer conductor assembly 2 in order to better adapt the snap-in structure 9.

Based on the above scheme principle and embodiment 1, embodiment 2 of the connector plug of the present invention is:

This example was further optimized on the basis of example 1. The key to this embodiment is that the connector insert also includes a locking end cap 12 as shown in fig. 9. In this embodiment, the snap structure 9 comprises a spring arm. The spring arm is suspended along the insertion direction of the outer conductor assembly 2, so that a floating gap 13 is formed between the side of the spring arm facing away from the outer conductor assembly 2 and the body of the plug housing 1, wherein the opening faces the insertion direction of the outer conductor assembly 2, and the spring arm is elastically floated. The locking end cap 12 is provided with a backstop structure. The retaining structure is used for being clamped into the floating pendulum gap 13 from the opening after the spring arm is clamped into the clamping space and the reinforcing clamping structure, so as to prevent the spring arm from falling out of the clamping space and the reinforcing clamping structure. Such a double locking action ensures the reliability of the fixed assembly relationship of the outer conductor assembly 2 with the plug housing 1. Under the action of the locking end cap 12, the pulling-out force which can pull the outer conductor assembly 2 out of the plug housing 1 is necessarily the same as the deformation force which can cause the spring arm to deform seriously. Therefore, the above-described structure also effectively increases the pulling-out force requirement for pulling out the outer conductor assembly 2 from the plug housing 1. Of course, in some situations where it is desirable to reduce tooling costs, the locking end cap 12 may be replaced with a locking tab. The locking piece is directly plugged into the floating pendulum gap 13 corresponding to the spring arm, so as to achieve the double locking effect.

In this embodiment, the outer conductor assembly 2 is further provided with a stop boss 14; the plug housing 1 is provided with a corresponding boss stop surface 15. After the outer conductor assembly 2 is inserted into the corresponding position of the plug housing 1, the stop boss 14 on the outer conductor assembly 2 is in stop engagement with the boss stop surface 15 on the plug housing 1 to prevent the outer conductor assembly 2 from moving in the insertion direction. Meanwhile, the spring arm is clamped into the clamping space and the reinforcing clamping structure so as to prevent the outer conductor assembly 2 from moving along a direction deviating from the insertion direction. The above structure is convenient for molding and also for assembling the outer conductor assembly 2 with the plug housing 1.

In addition to the foregoing, the stop structure may be a retaining wall 16. Specifically, the locking end cover 12 is an annular blocking cover, the cross-section of the ring body of the annular blocking cover is in a U shape to form an insertion groove 21, the locking end cover 12 is inserted on the plug housing 1 through the insertion groove 21, and a groove wall on one side of the insertion groove 21 forms a limiting wall 16 serving as a retreating structure. The plug housing 1 is provided with a plug-in end 22 corresponding to the plug-in groove 21, and the plug-in end 22 is clamped into the plug-in groove 21. By adopting the annular blocking cover, the inserting groove 21 can be formed through the ring body with the U-shaped section, and the inserting groove 21 is inserted with the inserting end 22 of the plug housing 1, so that a better sealing effect in the plug housing 1 is realized. The limiting wall 16, which is a retaining structure, is formed by the groove wall on one side of the insertion groove 21, so that the retaining structure can be simplified and the processing and the assembly can be facilitated. Meanwhile, the wall surface of the limiting wall 16 can provide a larger stopping surface for preventing the spring arm from retreating, and can completely block the retreating path of the spring arm. The retraction path of the spring arm is always blocked by the limiting arm no matter how the spring arm deforms under the action of pulling-off force. Therefore, by adopting the structure, the stopping effect of the stopping structure on the spring arm can be ensured to be always reliable. The limiting wall 16 in this embodiment may also be replaced by a limiting pawl. The limiting elastic claw stretches into the floating swing gap 13 of the elastic arm so as to block the retraction of the elastic arm through the elasticity of the limiting elastic claw. Thus the difficulty of the retraction of the spring arm can be further increased.

An anti-drop mechanism is also arranged between the locking end cover 12 and the plug housing 1. The anti-disengaging mechanism comprises an anti-disengaging groove 17 arranged on the groove wall of the inserting groove 21 and a clamping hook 18 which is arranged on the position of the plug housing 1 corresponding to the anti-disengaging groove 17 and is matched with the anti-disengaging groove 17, so that the locking end cover 12 is prevented from disengaging from the plug housing 1 along the inserting direction of the outer conductor assembly 2, and the locking end cover 12 can be reliably kept on the plug housing 1. The double locking action achieved on the basis of the locking end cap 12 can thus always be reliably present on the connector plug, so that an increase in the pull-out force of the locking end cap 12 and an increase in the reliability of the fixed assembly relationship between the outer conductor assembly 2 and the plug housing 1 are ensured to be stable. On this basis, the anti-disengaging mechanism specifically comprises an anti-disengaging groove 17 arranged on the limiting wall 16 and a clamping hook 18 which is arranged on the position of the plug housing 1 corresponding to the anti-disengaging groove 17 and is matched with the anti-disengaging groove 17, so that the structure of the anti-disengaging mechanism can be effectively simplified, and the anti-disengaging mechanism is easy to form and assemble. Of course, the locking end cap 12 may also be directly connected to the plug housing 1 by gluing. This makes the holding effect more stable.

In addition, the connector plug comprises a sealing rubber ring 19, wherein the sealing rubber ring 19 is pressed and held between the locking end cover 12 and the plug housing 1 by a groove wall opposite to the limiting wall 16 on the insertion groove 21. The arrangement of the sealing rubber ring 19 can prevent dust, water and other impurities from entering the connector plug, and influences the structure in the connector. Meanwhile, the sealing rubber ring 19 is pressed and kept between the locking end cover 12 and the plug housing 1 through the locking end cover 12, so that the sealing effect is more reliable. Of course, the sealing of the plug can also be realized by coating waterproof sealant on each part.

The portions not emphasized in this example correspond to example 1.
