Abstract
The utility model discloses a clamp for facilitating testing the electrical performance of a constant-temperature crystal oscillator. The clamp comprises a PCB (Printed Circuit Board); and the PCB is provided with a socket, an SMA (Shape Memory Alloy) terminal and a binding post, wherein the SMA terminal and the binding post are connected with the socket through leads. The clamp can be used for effectively increasing the testing efficiency and reducing short circuits and is simple in manufacture and convenient to use.
Description
Technical field
The utility model relates to a kind of anchor clamps, is specifically related to a kind of anchor clamps that make things convenient for the constant-temperature crystal oscillator electric performance test.
Background technology
In the production test procedure of constant-temperature crystal oscillator, often use crocodile clip and lead to couple together as p-wire, each functional pin that connects constant-temperature crystal oscillator is respectively tested.Inconvenient operation like this, inefficiency, and short circuit between going between sometimes.Therefore, the needs searching is a kind of can improve the various shortcomings in the above-mentioned test, the simple and practical tool of production.
The utility model content
The purpose of the utility model provides a kind of anchor clamps that make things convenient for the constant-temperature crystal oscillator electric performance test, can testing efficiency be provided effectively and reduce short circuit, makes simple, easy to use.
To achieve these goals, the utility model adopts following technical scheme:
A kind of anchor clamps that make things convenient for the constant-temperature crystal oscillator electric performance test wherein, comprise pcb board, and said pcb board is provided with socket, SMA terminal and binding post, and the SMA terminal is connected with socket through lead with binding post.
Further, said binding post is three.
A kind of anchor clamps that make things convenient for the constant-temperature crystal oscillator electric performance test wherein, comprise the testing cassete box body, and said box body is provided with the pcb board that has socket, and said box body both sides also are provided with SMA terminal and binding post; Said socket is welded in the corresponding hole of pcb board, and the SMA terminal is connected with socket through lead with binding post.
Further, said binding post is three.
The beneficial effect of the utility model is:
The utility model can effectively improve the efficient of constant-temperature crystal oscillator electric performance test, reduces human cost, reduces maloperation, and line is simple and convenient, and constant-temperature crystal oscillator that can compatible 3 kinds of dimensions.
Other advantages, target and the characteristic of the utility model will be set forth in instructions subsequently to a certain extent; And to a certain extent; Based on being conspicuous to those skilled in the art, perhaps can from the practice of the utility model, be enlightened to investigating of hereinafter.The target of the utility model can realize through the structure that is particularly pointed out in following instructions or the accompanying drawing and obtain with other advantages.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below through specific embodiment and combine accompanying drawing that the utility model is done further detailed description:
As shown in Figure 1; The utility model comprises testing cassete box body 1; On testing cassete box body 1, be provided with the pcb board 2, binding post 3 and the SMA terminal 4 that have socket; Socket on the pcb board is welded in the corresponding hole of pcb board, and SMA terminal 4 and binding post 3 are fixed on the side of testing cassete box body 1, and SMA terminal 4 is connected with socket through lead with binding post 3.Three binding posts 3 connect power lead, ground wire and output line respectively.
The utility model main structure body is a pcb board, and cabling is distributed in the top layer and the bottom of pcb board respectively, can pcb board be installed in other local uses, and pcb board as shown in Figure 1 is installed on the testing cassete box body 1; Also can be directly can do test and use to burn-on socket, SMA terminal and binding post of pcb board.Three binding posts connect power lead, ground wire and output line respectively.
In actual production, the utility model can increase the constant-temperature crystal oscillator of other dimensions again according to concrete needs, to increase compatible kind.
When the utility model uses in making, the first step: give the socket of burn-oning on the pcb board of the utility model; Second step: to the utility model connection lead of burn-oning; The 3rd step: pcb board is fixed; The 4th step: constant-temperature crystal oscillator is inserted corresponding position, can test.The utility model can use repeatedly.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Other modifications that those of ordinary skills make the technical scheme of the utility model perhaps are equal to replacement; Only otherwise break away from the spirit and the scope of the utility model technical scheme, all should be encompassed in the middle of the claim scope of the utility model.
