Description

TECHNICAL FIELD The present disclosure relates to an inspection connector that may be used in an end of line (EOL) process in the production of various connectors, and more particularly, to a pin push inspection connector that may be used in a function test for finally checking whether there is product abnormality after the assembly of various connector products is completed and checking whether pins of an assembled connector are pushed backward from correct positions and assembled (defective state). The present application claims priority to Korean Patent Application No. 10-2021-0061289 filed on May 12, 2021 in the Republic of Korea, the disclosures of which are incorporated herein by reference. BACKGROUND ART In general, a number of components are installed in a vehicle, an air conditioner, a refrigerator, a washing machine, a battery pack, or the like, and a complex wiring circuit is used to connect components to other components or supply power. Because the wiring circuit is quite complicated, it is effective to install the plurality of components and then form the wiring circuit. To this end, a cable connector implemented by connecting a plurality of cables is frequently used. A cable connector includes electrical cables, terminal pins connected to ends of the electrical cables, and a connector housing into which the terminal pins are inserted and fixed. The number of terminal pins or the size of the connector housing may vary according to a product to be applied. In the case of a connector, a plurality of terminal pins and a plurality of cables should be correctly connected, and the terminal pins connected to the cables should be correctly inserted into a connector housing. However, in a manufacturing process, for some reasons, the terminal pins may not be inserted into the connector housing to correct positions. In this case, because signal transmission or power supply through the connector is not performed, a product using the cable connector may not operate normally. Accordingly, in the case of cable connectors, only normal products are shipped through a final test process of checking there is malfunction after assembly and checking an assembled state of a plurality of terminal pins and a connector housing. Currently, X-ray imaging, Dino inspection (digital microscope inspection), etc. are performed to determine whether a connector has a poor pin assembled state, and because an inspection time and a tact time increase due to the process and productivity is deteriorated, improvement is required. DISCLOSURE Technical Problem The present disclosure is designed to solve the problems of the related art, and therefore the present disclosure is directed to providing a means for easily determining whether a pin of a connector under test is pushed, thereby omitting X-ray imaging and Dino inspection. These and other objects and advantages of the present disclosure may be understood from the following detailed description and will become more fully apparent from the exemplary embodiments of the present disclosure. Also, it will be easily understood that the objects and advantages of the present disclosure may be realized by the means shown in the appended claims and combinations thereof. Technical Solution In an aspect of the present disclosure, there is provided a pin push inspection connector including a first connector assembly having a front portion adapted to connect to a connector under test in a first direction and to be fixedly coupled to the connector under test, and a second connector assembly having a front portion connected to a rear portion of the first connector assembly in the first direction and provided so that a connection interval with respect to the first connector assembly is variably adjusted in the first direction or a second direction that is opposite to the first direction, wherein the second connector assembly includes at least one inspection pin provided therein to be connected to at least one terminal pin provided in the connector under test. The first connector assembly may include a first fastening hole extending in the first direction from a rear end portion of the first connector assembly, and the second connector assembly may include a length adjusting bolt passing through a body of the second connector assembly and screwed into the first fastening hole to a certain depth. The second connector assembly may further include a second fastening hole extending in the first direction and having a thread formed on an inner circumferential surface thereof, and a length fixing bolt screwed into the second fastening hole and provided to support the rear end portion of the first connector assembly. The length adjusting bolt may be provided in a pair, and the pair of length adjusting bolts may be respectively provided on a left edge and a right edge of the second connector assembly. The length fixing bolt may be provided in a pair, and the pair of length fixing bolts may be provided betwe
