Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, and more specifically to an SMP plug-in and pull-out separation tooling. Background Art

[0002] SMP is a new type of ultra-small blind-mate RF connector with the characteristics of high frequency of use, fast connection, and strong shock resistance. It is especially suitable for high-density blind plug-in between printed circuit boards, chassis, and cabinets. In recent years, it has been increasingly widely used in phased array radar, aviation, aerospace, and civil communications. The SMP series of ultra-small push-in connectors provides a good solution for modular dense installation applications and plays an extremely important role in the industry.

[0003] When the SMP connector is used, it can only be separated manually after being plugged in. Due to the limitations of its own structure and small size, and the fact that most of the connectors are used in narrow spaces, plugging and unplugging the SMP connector is time-consuming, labor-intensive, and difficult to operate. In view of this, we propose an SMP plug-in and unplugging tooling. Utility Model Content

[0004] The purpose of the utility model is to provide an SMP plug-in and separation tool to solve the problems raised in the above-mentioned background technology: the full-escapement or semi-escapement SMP connector can only be separated manually, and the pulling force is too large or is restricted by the small size of the connector itself or the narrow use space, resulting in the problem of time-consuming and labor-intensive separation of the SMP connector.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An SMP plug-in and pull-out separation tool comprises a contact head and a handle housing, wherein the contact head is provided with a groove along its axial position and the contact head extends into the handle housing;

[0007] A handle is provided through the handle shell, one end of the handle located in the handle shell is connected to the contact head, and the handle shell is in a slender tubular structure at one side close to the contact head.

[0009] Preferably, the outer wall of the contact head is provided with a plurality of convex rings with different diameters, an inclined surface is provided between two adjacent convex rings, and the diameters of the plurality of convex rings gradually decrease in a direction close to one side of the housing of the handle.

[0010] Preferably, the handle is a sliding fit with the handle housing.

[0011] Preferably, an elastic structure is provided inside the outer shell of the hand-held handle, one end of the elastic structure is connected to the inner wall of the outer shell of the hand-held handle, and the other end of the elastic structure is connected to the outer wall of the handle.

[0012] Preferably, the elastic structure is a spring.

[0013] Preferably, the contact head is connected to the handle via a guide pin.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model clamps the SMP connector through the cooperation of the contact head, the hand-held handle shell and the handle, and uses the handle to retract the contact head into the hand-held handle shell so that the contact head can clamp the SMP connector. Finally, the tooling is pulled outward as a whole to achieve the purpose of separating the SMP connector. The structure of the application is small in size and is suitable for use in narrow spaces. The SMP connector can be quickly plugged and unplugged to separate, saving time and effort, and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Example:

[0021] See also Figure 1-2 A SMP plug-in and separation tool comprises a contact head 1 and a handle housing 2. The contact head 1 is provided with a groove 103 along its axial position, and the contact head 1 extends into the handle housing 2. The contact head 1 plays the role of wrapping and fixing the SMP connector 4.

[0022] A handle 3 is provided in the handle housing 2, and one end of the handle 3 located in the handle housing 2 is connected to the contact head 1. Figure 1 As shown, the end of the handle housing 2 close to the contact head 1 is a slender tubular structure, which is convenient for use in a narrow space.

[0023] In the present application, the handle 3 is slidably matched with the handle housing 2 , and the handle 3 can slide along the handle housing 2 to achieve reciprocating extension and retraction of the handle 3 and the handle housing 2 , so that the contact head 1 can be extended or retracted into the handle housing 2 .

[0024] The handle 3 is composed of a connecting portion and a holding portion. The holding portion is located outside the handle housing 2 , and the connecting portion extends into the handle housing 2 to be connected with the contact head 1 .

[0025] In the present application, the groove 103 separates one end of the contact head 1 into two oppositely disposed semi-arc structures, so as to facilitate the insertion of the SMP connector 4 between the two oppositely disposed semi-arc structures. When the contact head 1 extends out of the handle housing 2, the two semi-arc structures will be slightly opened from each other, and a groove is provided on the inner wall of the contact head 1, which can clamp the end of the SMP connector 4.

[0026] In a possible embodiment, the contact head 1 is made of elastic material to facilitate the insertion of the SMP connector.

[0027] In the present application, the outer wall of the contact head 1 is provided with a plurality of convex rings 101 of different diameters, and a slope 102 is provided between two adjacent convex rings 101. The diameters of the plurality of convex rings 101 gradually decrease in the direction close to the side of the handle shell 2. When the contact head 1 moves into the handle shell 2, the handle shell 2 applies a certain force to the two semi-circular arc structures on the contact head 1, so that the two semi-circular arc structures approach each other and clamp the SMP connector 4.

[0028] By setting the convex rings 101 of different diameters, when the sizes of the SMP connector 4 are different, the convex rings 101 of different diameters will contact the inner wall of one end of the handle shell 2, and the inner wall of one end of the handle shell 2 will apply an extrusion force to the convex ring 101, so that the two semicircular arc structures of the contact head 1 clamp the SMP connector 4, and the inclined surface 102 is set to facilitate the retraction of the contact head 1 into the handle shell 2.

[0029] In the present application, an elastic structure is provided inside the handle housing 2, one end of the elastic structure is connected to the inner wall of the handle housing 2, and the other end of the elastic structure is connected to the outer wall of the handle 3. After the handle 3 is pushed out of the handle housing 2 by the elastic structure, the handle 3 only needs to be released, and the handle 3 will automatically return to its original position under the thrust of the elastic structure, so that the contact head 1 is retracted into the handle housing 2.

[0030] The elastic structure may be a spring, one end of which is connected to the inner wall of the handle housing 2, and the other end of which is connected to the outer wall of the handle 3. When the handle 3 and the handle housing 2 are relatively contracted, the spring will be compressed.

[0031] In the present application, the contact head 1 and the handle 3 are connected via a guide pin for easy disassembly.

[0032] Working principle: first hold the hand-held handle shell 2, and then press down the handle 3 with the palm of your hand. The inside of the handle 3 is connected to the contact head 1 through a guide pin and is designed with a spring structure. After pressing down, the contact head 1 can extend out of the hand-held handle shell 2. When the contact head 1 extends out of the hand-held handle shell 2, the end part of the contact head 1 will naturally open slightly. At this time, the contact head 1 can be inserted and slightly clamped into the SMP connector 4, and then the handle 3 is slowly released and pressed down. Under the action of the spring, the handle 3 will automatically return to its original position, so that the contact head 1 shrinks back into the hand-held handle shell 2. When the contact head 1 shrinks into the hand-held handle shell 2, the inner wall of the hand-held handle shell 2 applies a certain extrusion force to the two semi-circular arc structures on the contact head 1, so that the two semi-circular arc structures are close to each other, which can completely fix the SMP connector 4. Finally, the tooling is pulled outward as a whole to achieve the purpose of separating the SMP connector 4.

[0033] The full-escapement or semi-escapement SMP connector can only be separated manually, and the pulling force is large, while the connector itself has a small size and most of the usage scenarios are also relatively small. All of the above results in time-consuming, labor-intensive and difficult operation when separating the SMP connector. This tooling can quickly plug and unplug the SMP connector, which solves the above problems well.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
