Description

Technical Field

[0001] The utility model relates to an N-type elbow connector. Background Art

[0002] The N-type elbow connector is a specific type of elbow connector, which is usually used in microwave and radio frequency (RF) applications. "N-type" refers to the type of connector, which was jointly invented by Paul Neill of Amphenol and Walter C. Houser of AT&T in the 1940s. The N-type connector is a threaded connector and is widely used in high-power and medium-frequency applications. The design of the N-type elbow connector allows signals to be transmitted at a specific angle (usually 90 degrees) in a microwave or RF system, which is very useful for the layout and space optimization of equipment. This type of connector is usually used in antenna systems, test equipment, communication equipment, and other applications that require RF connections.

[0003] Currently, for the conventionally produced elbow connectors, the split press-fitting method or the method of cutting slots in the insulator is usually adopted, and the assembly is complicated. When making the component finished product, the performance will be affected due to improper press-fitting or too large cutting slots in the insulator, and there is a hidden danger of unstable performance. At the same time, the labor cost of this production method is relatively high, and the square shell is prone to scratches during use, resulting in product loss. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an N-type elbow connector that adopts the method of expanding the blind cover hole in the reverse direction from the port, which is integrally formed, saving material loss and reducing labor cost.

[0005] Based on the technical problems existing in the background art, the utility model proposes an N-type elbow connector, including a housing, a bent adapter sleeve is connected to the rear end of the housing. The overall vertical cross-section of the bent adapter sleeve is circular, a tail press is installed below it. The other end of the bent adapter sleeve is provided with a blind cover hole, and a blind cover is correspondingly installed in the blind cover hole. An insulator is installed inside the housing, and a inner conductor is inserted through the middle of the insulator.

[0006] Preferably, a groove is provided on the inner wall of the housing, and the groove is located outside the insulator and is V-shaped.

[0007] Preferably, the insulator is inserted into the housing from the blind cover hole, and the inner conductor is installed in the middle of the insulator and extends out of one end of the housing.

[0008] Preferably, the cross-sectional dimension of the bent adapter sleeve is larger than the cross-sectional dimension of the housing, and the tail press is vertically installed at the bottom of the bent adapter sleeve.

[0009] Preferably, the outer shell and the elbow adapter sleeve are of an integral structure, and a tightening thread is provided on the inner wall of the blanking cover hole opened at the tail of the elbow adapter sleeve.

[0010] Preferably, a docking thread is provided on the blanking cover installed inside the blanking cover hole, and the docking thread cooperates with the tightening thread.

[0011] Compared with the prior art, the N-type elbow connector proposed by the present utility model adopts the above technical solutions and achieves the following technical effects:

[0012] 1. By the way of expanding the blanking cover hole reversely from the port, the present utility model abandons the structures of insulator slitting and port pressure contact heads, and is integrally formed, saving material loss and reducing labor costs.

[0018] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection or communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0019] In the present utility model, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature has a lower horizontal height than the second feature.

[0020] Referring to Figures 1-3 , the present utility model provides an N-type elbow connector, which includes a housing 1. A bend adapter sleeve 2 is connected to the rear end of the housing 1. The overall vertical cross-section of the bend adapter sleeve 2 is circular. A tail press 3 is installed below it. The other end of the bend adapter sleeve 2 is provided with a blanking plug hole 4, and a blanking plug 5 is correspondingly installed in the blanking plug hole 4. An insulator 6 is installed inside the housing 1, and an inner conductor 7 is inserted through the middle of the insulator 6.

[0021] In this embodiment, based on the usual square bend adapter sleeve 2, it is designed as a circular bend adapter sleeve 2. When the original square is numerically controlled for production, it is time-consuming and material-consuming. Sometimes, a single chuck needs to be opened, or the insulator is slit or the contact head is riveted. The assembly process is complicated, and the end face is sunken, posing a hidden danger of unstable installation performance. In this embodiment, a structure of expanding the blanking plug hole 4 in the reverse direction from the port is adopted. With a circular shape replacing the square appearance, while maintaining the strength, reasonable structure and stable performance, the labor cost is reduced and unnecessary material loss is reduced.

[0022] Specifically, a groove 8 is provided on the inner wall of the housing 1. The groove 8 is located outside the insulator 6 and is V-shaped.

[0023] In this embodiment, at the corresponding position inside the housing 1, a groove 8 is formed to make it "V"-shaped, reducing the performance difference caused by reverse assembly and making the product performance more stable.

[0024] Specifically, the insulator 6 is inserted into the inside of the housing 1 from the blanking plug hole 4. The inner conductor 7 is installed in the middle of the insulator 6 and extends out of one end of the housing 1.

[0025] Specifically, the cross-sectional dimension of the bend adapter sleeve 2 is larger than the cross-sectional dimension of the housing 1. The tail press 3 is vertically installed at the bottom of the bend adapter sleeve 2.

[0026] Referring to Figure 2 , the housing 1 and the bend adapter sleeve 2 are of an integral structure. A tightening thread 41 is provided on the inner wall of the blanking plug hole 4 opened at the tail of the bend adapter sleeve 2.

[0027] Specifically, a butt thread 51 is provided on the blanking plug 5 installed inside the blanking plug hole 4. The butt thread 51 cooperates with the tightening thread 41.

[0028] In this embodiment, the overall N-type elbow connector adopts the method of expanding the blanking hole 4 in the reverse direction from the port, abandoning the structure of the insulator 6 slitting and the port pressure contact head, so that the outer shell 1 and the elbow adapter sleeve 2 are integrally formed, saving material loss and reducing labor costs during the production process. Moreover, in this embodiment, the elbow adapter sleeve 2 is generally circular, which is consistent with the overall shapes of the outer shell 1 and the tail pressing 3, greatly saving material costs and eliminating product losses caused by scratches on the appearance of the square outer shell.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
